SEER Ratings“SEER” should not mystify you, but could save you lots of $$!


If you need to purchase a new A/C system, you have no doubt been presented various SEER-rating options. These determine the efficiency and initial cost of your unit. A higher SEER rating will cost you more initially, but you will save money in the long run. The question often becomes, yes, but how much?

The Details: Numbers

Basically, the higher the seer rating, the more money you save on your air conditioning bills. SEER stands for “Seasonal Energy Efficiency Rating”–aka how much electricity is this thing gonna eat up this summer?!

Marathon Air can guide you through the options and help you decide which SEER is right for you. Just a few short years ago, the feds created a new regulation that require all newly manufactured air conditioning units to have at least a 13 SEER rating. However, the choices range from 13 all the way to 21.

How much can you save on higher SEER?

Well, for every $100 you spend running an 8 SEER air conditioning unit, you would save:

  • $12 on a 9 SEER AC unit (spending only $88).
  • $19 on a 10 SEER system (spending only $81).
  • $27 on an 11 SEER air conditioner (spending only $73).
  • $33 on a 12 SEER HVAC unit (spending only $67).
  • $38 on a 13 SEER Commercial Air Conditioners (spending only $62).
  • $42 on a 14 SEER A/C (spending only $58).
  • $46 on a 15 SEER AC unit (spending only $54).
  • $49 on a 16 SEER HVAC unit (spending only $51).
  • $52 on a 17 SEER air conditioners (spending only $48).
  • $55 on an 18 SEER A/C system (spending only $45).

AC programmable thermostatA recent survey showed that interest among realtors and their clients for home technology is high.

In the past couple of years, 9/10 of realtors have been involved in buying, selling, or showing a home with technology ranging from more established systems such as monitored security to newer technologies like energy management systems. This would include programmable A/C thermostats, which add an elegant look combined with energy savings to any home.

Over half of the realtors report they are excited by these homes and believe their clients’ enthusiasm for technology is identical to their own, with almost two-thirds of realtors stating their clients like seeing newer technology when they view new homes for potential purchase.

The survey of almost 2000 realtors who were members of the NAR (National Association of Realtors), clarified realtors’ experiences with homes which have installed technologies and how they view the technology in relation to the home sale.

“There is a strong relationship between home technologies and the real estate market,” stated Rhonda Daniel, manager of market research, “the industry can help prepare realtors to be comfortable in discussing these types of systems with their clients.”

Most surveyed realtors wanted to learn more about installed home technologies and the surveyors noted that efforts should begin to teach them about these technologies now so that they would be ready for the eventual positive movement in the real estate market.

The take home message? Installing a programmable thermostat could be a smart move if you are trying to sell your home. And if you already have one, you should instruct your realtor to emphasize the energy saving features to potential buyers.

Ice Machine Refrigeration RepairCommercial HVAC and Refrigeration Technicians Are Not the Same–And How this Could Save You Lots of Money

Many Orlando restaurants, convenience stores, schools, churches, clubs, bakeries, delis, and bars have all sorts of refrigeration equipment.  These Orlando businesses rely on those pieces of commercial air conditioning and refrigeration equipment always working properly.  But the primary job of business management is not to maintain commercial equipment like ice machines or coolers. Their job is to serve their customers, often by providing food, liquor, or entertainment.  So when their refrigeration equipment stops working what do they do?  Well, these days, very often they go to their computer, phone or tablet, and shop Google for a reliable HVAC or refrigeration service technician.  Bing is another great place the look.  But, unless Marathon Air somehow magically reached the top of those searches, and you called us, you most likely will be shocked when the tech hands you the bill for your commercial air conditioning or refrigeration repair job.

ice machine repair storyA Faulty Ice Machine Repair Troubleshooting Story

I like to give examples of what I find on my daily run of repairing commercial air conditioning, refrigeration equipment and ice machines in the Orlando area.  One day I went to one of my long-time customers.  He always calls Marathon Air for his commercial air conditioning, ice machine and refrigeration repairs.  This particular customer, like many of my customers, owns several gas/convenience stores. He had recently opened a new location, where he still had the old manager carried over from the old owner.   They had inherited two large ice makers, both of which were not producing ice.

What The Other Ice Machine Service Tech Told Them

I asked the manager what the previous ice machine service tech told him was wrong with these ice machines.  He said the previous guy said both ice machines needed to be replaced because their evaporator plates were bad.  The old service tech said he was barely able to keep them working and they would not last much longer.  Well, I worked on the first machine and discovered the evaporator plates to be in nearly perfect condition.  Upon closer inspection, I realized the problem was a faulty harvest assist regulator valve.  I changed the valve, which is a fairly cheap repair when compared to buying a new ice machine, and the ice came off the evaporator plate like a new machine.

Ice Machine Service, Used Machines with Warranties, and the Dilemmaone thousand dollar repair bill

I have no doubt that the old owner called that tech on a regular basis, which allowed the former refrigeration service company to charge the old owner money to reset the machine and probably add extra freon to increase the coil temperature (which, by the way, damages the compressor) to help with the harvest of ice.  The old tech also gave him the option of buying a used ice machine for $1000.00  with a one year warranty.  Well, there is a very good chance that the used machine would not have been as good as the ice machine they already had.  And I bet the “warranty” from this guy was as worthless as his ability to repair these ice makers (and that assumes that company stays in business long enough and has enough ethics to service the warranty–not always a guarantee in this business).  And he easily could have taken the old ice machine and sold that unit to another unsuspecting soul, maybe for another $100o with another year warranty.  Sounds great, huh?

Was that Ice Machine Repair Tech Lying or Simply Unskilled?dishonest ice machine repair tech

I have no idea whether the old repairman was incompetent or if he was actually lying to make more money, or both.  Either way, the customer had no way of knowing, so continued paying for bad ice machine, refrigeration and commercial air conditioning service.  In sharp contrast, at Marathon Air, we are honest, fair, and highly skilled.  We know how to repair refrigeration and commercial air conditioning equipment the right way.  I encounter far too many customers trying to find and hire the absolute “cheapest” repair people.  In the end, what they thought would be cheaper costs them huge amounts in the long run.  This type of scenario is also common with big “professional” commercial air conditioning and refrigeration companies all over the Orlando area.

honest ice machine and refrigeration technicianThe Solution to Your Ice Machine Repair Problem?  Really.

Really the only way to trust that your refrigeration and commercial air conditioning equipment is in good hands is to call Marathon Air.  Having the job done correctly and honestly, for a fair price, will save you money on repairing all of your equipment.  I do not know what else to say, except that not believing this post would be a mistake.

Frustrated Refrigeration Repair CustomerWell I have another story where the customer was told they needed a new unit when what they really needed was a new refrigeration repair technician.  Actually this establishment was told to get two new units.

The story begins where the bar had two beer coolers.  The first cooler stopped working so they called in a big name refrigeration service company to fix it.

First Refrigeration Repair Tech Expensive Advice: Buy New Beer Cooler

The refrigeration repair technician diagnosed the problem correctly, which was the unit was out of refrigerant.  Afterwards, he added a valve to the unit and charged it up.  The valve he installed was a temporary type that should not have been left on because they eventually leak.  He could not pull the condenser out from the unit to work on it because he did not know that a hidden screw held the condenser in the cooler.  He used a leak detector to find the leak but could not locate the leak.  His final analysis was unit is bad due to undetectable leak, so he told the customer that the unit needed to be replaced.

After the technician left, the cooler worked for one day and then stopped cooling.  In addition, a second beer cooler stopped working.  The customer was going into the weekend with both coolers out.  Somehow they got Marathon Air’s phone number and I stopped in to take a look.  What I found was the second cooler had a bad compressor and needed a new compressor.  They agreed to repair it but this was Friday afternoon and I could not fix it until Monday morning, so I focused my attention on the unit the previous technician said was garbage.

Reality: Leak Repairable

This was the beer cooler with a refrigerant leak.  I went about pressure testing unit with high pressure nitrogen. After thirty minutes of searching, I found the leak in a capillary tube.  The leak was in a hard to reach location, but after much work I was able to repair the leak.  Unit was leak tested and leak free.  I charged the unit with refrigerant and the unit began working  like new.

It was now after six p.m. on a Friday and I at least got one of the two beer units running for their weekend.  As I was leaving, the customer showed me a two door freezer in the kitchen that was at 50 degrees.  They said another refrigeration repair guy told them this needed to be replaced too.  I told them I would be back Monday to fix the other beer cooler and at that time would look at the freezer. On Monday I replaced the compressor on the second beer cooler.  Now both beer coolers were running like new.

The two door True reach-in freezer was next up.  I found its  evaporator coil iced up.  I defrosted the evaporator coil.  Then I checked the thermostat which was good.  Next I checked the compressor, condenser fans, evaporator fans, defrost heaters, refrigerant levels, door gaskets, door heaters,  and drain line heater.  All these systems were operating perfectly.  So the only thing left, which I suspected all along, was the defrost timer.  I tested the timer and it was bad.  Without a  defrost cycle, the freezer evaporator coil will ice up and the  freezer will not get cold.

Get Best Refrigeration Repair Advice From Marathon Air

The director of operations was with one of the owners and happened to walk by just as I was finishing up my diagnosis of the freezer.  He was telling the owner that business was good and they were making money except for the fact that they were facing the purchase of a three thousand dollar freezer and about thousand five hundred  dollars for each beer cooler. The director of operations was ecstatic that I fixed the two beer coolers and could not believe it when I told him he needed a defrost timer that would cost 275.00 dollars.

Save Real Money

Save Money On Refrigeration RepairsAll told the repairs came to one thousand dollars.  They saved five  thousand dollars.  In addition, one of the beer coolers is like new, since a compressor is the most expensive part of the cooler.

I cannot believe how inept some repair service people are.  In this case the service person that told them to get a new beer cooler charged them 375.00.  For what?  He charged up the cooler with a refrigerant that leaked out in one day and left the customer with the prospect of buying a new cooler for fifteen-hundred dollars.  A different repair guy told them to get a new freezer. Lucky for the owner when after the third unit failed they called Marathon Air.


Where Does the Time Go?

We recently finished installing a commercial air conditioning system for Everest Concepts in Orlando.  They are an awesome catering company with a very stylish designed facility, great for parties and weddings.  We installed one system in their warehouse a few weeks ago and they are ready to schedule system number two.  We also installed a sixteen SEER residential unit for a Delta employee this week.  We are also cleaning and repairing a multi-unit compressor system for Heller Brothers, a citrus packer located in Winter Garden. They are getting ready to close for the summer, but we look forward to seeing and helping them again when the open for business in the fall.  We’ve also been driving to Tampa several times lately for numerous a/c and refrigeration repairs for several Long John Silvers locations.  And, of course, we’ve been doing about a thousand other things.  Summer isn’t here yet, but it feels like it has arrived to us.  There simply is not enough time in the day.

Cleaning Condenser Coils after A/C preventative maintenanceClean Your Air Conditioning Condenser Coils During Bi-Annual A/C Preventive Maintenance

Summer is upon us.  It is May first and, in Florida, that signals the beginning of 6 months of hot, hot, hot.  The ground hog and his shadow means something to people up north, as far as how much winter is left. But in Florida, when the Gator comes out of his hole, it means May, June, July, August, September and October will be hot and humid.  Your air conditioner will be worked like a monkey on a hot tin roof (don’t ask me what that means).  But let me just say that you should have your air conditioner maintained or given an a/c preventive maintenance checkup or annual tune-up or whatever else you want to call the process of checking and cleaning your expensive equipment, some of which sits outdoors in the elements day after day, month after month, and year after year.

Condenser Coil Cleaning Not Part of Most Standard Preventative Maintenance Agreements or Tune-Ups

One critical aspect of maintenance that helps a lot with extending the useful life of your air conditioner, as part of a comprehensive preventative maintenance plan, is cleaning the condenser coil.  This is above and beyond your typical a/c preventative maintenance “14 point” or even “24″ point check ups, or whatever numbers other air conditioning companies might dream up in their marketing efforts.  Basically this isn’t usually included in standard (that is, the cheapest) preventative maintenance agreements you might find from most air conditioning service companies.  But cleaning your air conditioning coils is important and should be done regularly.

Where You Can Find the Condenser Coil, Which Most Likely Is Dirty

The condenser coil is located inside the condensing unit.  If you have a spit system, the condensing unit is the outdoor part of your system.  If you have a package or rooftop system, then the condensing unit is only part of the outdoor unit.  All right now, be honest, have I put you to sleep yet?  My guess is that no one in the whole wide web or world is going to read this anyway.  Seriously, this is an a/c website.  But let’s just say you are still here reading.  And lets also say that the thing outside with the fan is the condenser coil (the thing with the accordian looking metal fins).  Well that piece of metal needs to stay clean, which means that you must sometimes clean it.  Dust and dirt will accumulate on the coils and between the fins over time.  The coil may even look clean but, unless you had it cleaned in the last few months, there is a high probability that it is not clean.

You Can Clean The Condenser Coil Yourself, If You Really Want to Get Dirty

If you want to clean it yourself, you can (warning: it’s a dirty, messy, not fun job).  Just take the fan motor and fan blade off the unit.  Make sure the power is off.  Disclaimer: if you did not know that you should turn the power off, do not do this job.  In that case, you should call a professional company that provides air conditioning preventative maintenance services.  So, anyway, remove the fan and get a garden hose.  Spray water from the inside of the shell to the outside of the unit.  You will see a lot of dirt running out with the water.  They make professional cleaning solutions that help get the dirt off.  Personally, I prefer just using water.  I am usually concerned that all the chemicals will not come completely off and possibly eat at the fins later. And I can get coils really clean using only water.  If you do this yourself, make sure you spray the water straight at the coil, rather than from the side, or you will damage the fins.  Damaging the fins is easy to do because they get bent with the slightest amount of improper pressure.

Cleaning Your A/C Condenser Coils is Important and Will Save You $$ in the Long Run

Cleaning the coils will save you money by making the air conditioner, whether it is commercial or residential, more efficient because a clean coil will eject heat (which is ultimately the job of any air conditioner) much better than a dirty coil.  A clean condenser coil will also help your fan motor work in a cooler environment, and lower your head pressure, thereby allowing your compressor to run cooler.  A cooler running compressor lasts longer.

Our Prices for Cleaning Air Conditioner Condenser Coils on Outdoor Units

Cleaning the condenser coils, as part of bi-annual preventative maintenance, is something everyone should do for their air conditioning unit at least twice per year.  If you want Marathon Air to clean your coils, carefully and professionally, just give us a call.  Our prices for cleaning outdoor air conditioning condenser coils range from $150 to $240 dollars per unit, which includes the cleaning only (preventative maintenance and inspection involves additional work and therefore charges).


Ice Machine Repair 101:

How Your Ice Machine Makes Ice

Ice machine repair can be tricky, but we will start with an obvious proposition.  You need ice to make water. Now that we’ve cleared the simple concept, let’s dig deeper. There is a a mechanical device within all ice makers that automatically fills the water reservoir.  There are two devices, most commonly, for water inlet control.  Those are a float switch and a electromagnetic solenoid.  The float switch is inside the water reservoir.  If you look, you can see a round or square plastic float inside the water reservoir, which is connected to an arm.  When the water level drops, the float in the water reservoir drops, which opens a valve that allows water into the pan/reservoir.  On the other hand, the water inlet solenoid is usually located in the ice machine near where the water line enters the unit.  The solenoid receives electrical voltage from a control panel, which controls the opening of the valve, and allows a certain amount of water to fill the pan.

How Your Ice Machine “Knows” That There is Enough Water to Make Ice

Different ice machine manufacturers use varying methods for the ice machine to detect when enough water has entered the water pan.  If using a float switch, the water pan remains full of water.  Water  enters the pan whenever the water level drops.  The use of a water inlet solenoid requires a second sensing device, which tells the solenoid when to turn off the flow of water coming into the water pan.  Some ice machines use a water float that switches off the water inlet solenoid when the water raises to a certain level.  Other machines use water sensors for the same detection.  The water sensor is usually part of a DC voltage control board.  The sensor is simply a metal probe that completes a ground when the water touches the metal probe.  When the ground for the DC circuit is complete, the computer board inside the ice maker closes the AC current to the solenoid.

In summary, if your ice machine does not get enough water in the water reservoir at the beginning of the ice making freeze stage, you need to check the water inlet valve.  You can find the water inlet valve by following the water line that goes into the ice maker.  This will lead you to this valve.

Lime Scale Problems

Lime scale is usually what causes a float valve to stop working.  This scale builds up in all ice machine when the water freezes, turns into ice minerals, which will not freeze but stay behind in the water pan to make the dreaded lime scale. Over time, this build up clings to the inside parts that come into contact with water.  Eventually, the lime scale will damage the inlet valve or prevent it from allowing water to flow through the valve.  This build up will also damage any inlet valve controlled by a solenoid.  In those cases, the valve can be taken apart and cleaned.  You can find a screen on the inlet side of the valve, which collects this lime scale.  You may attempt to clean this screen if you are able.  Also, you should clean the diaphragm of the valve.  However, very often when the inlet valve becomes unworkable, a replacement is in order. Usually by the time an inlet valve becomes fouled, it needs to be replaced with a new one.

Bad Leads to Worse: Failure to Properly Clean Small Parts May Lead to Overall Equipment Failure

You can control scale building up in the water inlet value by using a good ice machine water filter.  We will save the water filter discussion for another blog entry.  But another way to control the destructive scale buildup is by cleaning your ice maker.  When I suggest that you clean an ice machine, I do not mean taking stainless steel cleaner to the outside of the cabinet.  The only way to properly clean an ice machine is to use a professional cleaning solution, specifically approved for ice machines,and follow the manufactures recommended procedures.  We will save a detailed cleaning discussion for another day, but you should know that if you clean with the wrong chemical, you can destroy your evaporator plate.

In A Nutshell

So we’ve come full circle to get back to the idea that your ice machine needs water to make ice.  So simple.  The key to repairing ice machines is to make sure this water is flowing.  This means first checking the water line going into the machine.  If that is working, the next step involve in repairing an ice machine is making sure your water inlet valve is working.  We’ll save filters and cleaning for another day.

But the take home message should be that preventive maintenance to reduce scale buildup with a water filter and remove scale with regular cleaning is the best defense against water inlet valve failure.

The Ever Burning Question: Should You Repair or Replace Your Air Conditioner?

Should you repair, replace or replace even if not in need of repair?  I would like to give you some ideas on whether to replace or repair an air conditioner.  The following is not meant to be a comprehensive discussion of air conditioner replacement.  From my years of experience as an air conditioning contractor in Orlando, Florida, I will try to touch what I think are important considerations regarding air conditioner replacement.

First, if you are contemplating air conditioner replacement, you should call us at Marathon Air.  We will carefully evaluate what is wrong and give you an estimate regarding what the repair will cost you.  We help our customers evaluate the air conditioner replacement question many times every day.

Less Than Five Years Old: Repair Your A/C

Now if your air conditioner is less than five years old it is probably still covered by a warranty on the compressor.  This is the most expensive part of a system.  So, if your system is less than 5 years old, the answer to the air conditioner replacement question is always to repair any problem.

More Than Five Years Old: Possibly Replace Your A/C, Or Maybe Not, Depending

However if your air conditioner is over five years old it may not have warranty coverage.  This means a compressor or evaporator repair (which is major) will cost more money.  And air conditioners older than this will most likely be less efficient than newer models.  The reality is that air conditioners are machines, which means that they can be repaired indefinitely.  However, an air conditioner built 25 years ago may be running just fine, technically “needing” no repair, yet be using much more electricity than a new efficient air conditioner, which may make it more economical to replace it.  Thus, any unit say over 15 years is not worth any major repair.  For example, a compressor repair might cost 1800.00, while a new system may cost 4500 dollars, which is a difference of  2700 dollars.  You can easily save  700 dollars a year on electric cost, so in just over 3 years the extra electric cost would have paid for your new system.  The electric savings varies and needs to be evaluated on a case by case basis.  Government and utility rebates can also make the payback of air conditioner replacement even more advantageous.

No One Wants to Be Hot

Another reason to replace a system is to gain reliability.  A business open to the public is not inviting if the air conditioning is not working and the temperature spikes to ninety degrees.  Constant AC outages make both the employees and customers equally unhappy.  A new system is less likely to fail, which keeps everyone content.

Do You Plan On Sticking Around For A While?

If you are leasing your business location, with plans to move your business soon, then obviously you should not replace the old HVAC unit.  On the other hand, if you are planning to stay at your current location for a long time, you may reap the energy efficiency savings by an air conditioner replacement with a new energy efficient unit that is more reliable than the old one.

We Work All Over Central Florida

Marathon Air provides primary commercial air conditioning (although we welcome and perform some residential), refrigeration and ice machine repair to cities all over Central Florida, including: Winter Garden, Ocoee, Clermont, Apopka, Altamonte Springs, Windermere, Dr. Phillips, Kissimmee, Orlando, Winter Park, Maitland, Casselberry, Oviedo, Deltona, Deland, Longwood, Lakeland, Mount Dora, Longwod, Sanford, Heathrow, Eustis, Tavares, Leesburg and all points in between.

antibacterial UV lights for commercial air conditioning systemsAnti-Bacterial Lights: Protect the Air You Breathe

Anti-bacterial UV lights are becoming more popular with some of our customers. These are ultra-violet lights, which we can install inside your supply air ducts. These are typically overhead, in your ceiling. So before any air is released into your room, for you to breathe, the air passes over these UV lights. In a nutshell, these lights kill mold and bacteria.

The U.S. Government Requires Them!

Ultraviolet light has been used and trusted for many years as an effective tool in processing food, purifying water, and sterilizing medical equipment. For that reason, more and more people are starting to utilize this same technology, i.e., antimicrobial UV lights, to purify the air that they breathe inside their HVAC systems. As a matter of fact, the federal government requires that UV lights be installed in all government buildings–above cooling coils–to avoid the spread of dangerous microorganisms in ventilation systems.

Improve Your Indoor Air Quality (“IAQ”) With UV Lights

A leading U.S. testing agency, Microbe Management, Inc, has performed three separate tests to determine the effect of UV lights on indoor air quality. They concluded through testing that UV light is an important part of a complete home or business approach to improving the quality of the air you breathe.

HVAC Removes Water From The Air, Which Leads To Mold In Your Ductwork

Experts evaluating the study by Microbe Management could not agree about the primary cause of poor indoor air quality. But, they agreed that the prevention of the growth and spread of microorganisms, like fungi and mold, is the solution to improving indoor air quality over time. Therefore, you should eliminate unwanted sources of moisture in your home or business. You should also consider trying to control mold growth, which can grow rapidly in the moist conditions inside your air conditioning coils and air ducts. Since HVAC systems partly remove water from the air, they are very moist. This water leads to mold growth, particularly in Florida, with our high humidity. Mold and other dangerous microorganisms start with this water and then keep growing on your air conditioning coils. The bad news is that when the blower turns on, mold spores travel throughout your ductwork and, eventually, your entire home or business.

Antibacterial UV Light for Commercial Air ConditionersThe Solution: Antimicrobial/Antibacterial Lights

Installation of antimicrobial UV lights in your air conditioning system may help control the spread of these microorganisms throughout your HVAC system. Special ultraviolet lights can destroy up to 99% of air contaminants including:

  • Mold
  • Mildew
  • Bacteria
  • Fungi
  • Dust mites and their feces
  • . . . and much more

Your Air Ducts: Prevent The Spread of Mold By Starting At The Source

Microbe Management conducted one test to measure the effectiveness of installing a UV light aimed directly at the air conditioning coil surfaces. The test results seemed clear. The side of the air conditioning coil that had been exposed to UV light was completely clean and had no mold growth. But mold continued to grow on the side that did not have UV light exposure. This test confirmed that an antimicrobial UV light aimed at the coils properly would prevent mold growth in HVAC systems.

Where We Put This Light For Maximum Clean Air Effectiveness

Importantly, the antimicrobial UV light must be installed in the proper position. Ideally, the light should be installed directly over the air conditioning coils to prevent the growth of any dangerous allergens, such as mold and mildew. The light will prevent the mold from being distributed throughout your air duct system and, eventually, your entire home or business. If installation in that location is impossible, then you should install the UV light on the supply or return side of your ventilation system.

Marathon Air Installs Antimicrobial Lights

Marathon Air installs antimicrobial UV lights to help control the growth and spread of mold in your home or business air duct system. By using energy from high-intensity UV-Clamps, these lights reduce offending organisms, which otherwise cycle through your HVAC system. We know how to properly mount the ultraviolet light in the air conditioning system of your home or business. The ultraviolet antimicrobial/antibaterial light then sterilizes dangerous air contaminates as they pass over the UV light. This can help keep you and your family or employees healthier. The other good thing is that antimicrobial lamps do not need much maintenance and are not expensive to operate. So give us a call today–and take one important step in breathing cleaner air!
