Air Conditioning Guide: Refrigerant Leaks

Monday, June 25th, 2012

Your St Petersburg air conditioner is filled with a chemical compound called refrigerant. This substance is what allows your air conditioner to remove heat from and dehumidify your home. It is a necessity, but it is also a dangerous chemical that, if released, can cause damage to the environment.

Why Refrigerant Is Dangerous

There are many types of refrigerant but most air conditioners use either R-22 or Freon coolant – depending on their age. Newer air conditioners may use R410-A refrigerant, an environmentally safer alternative.

All of these refrigerant types are chlorofluorocarbons or CFCs. These chemicals are controlled substances by the Environmental Protection Agency, meaning they must be properly removed and disposed of. Because your air conditioner does not consume any of coolant in operation, it should never need to be refilled unless there is a leak. Such a leak should be stopped immediately due to the immense damage CFCs can do to the environment. If you suspect a leak, you should call a St Petersburg air conditioning professional to inspect your air conditioner.

Damage to Your Air Conditioner

Beyond the environmental issues posed by a refrigerant leak, the biggest problem you will face is damage such leaks can cause to your air conditioner. Low refrigerant levels put undue stress on your compressor and can lead to damage in almost every part of the device.

Not only that but the air conditioner won’t work as efficiently. A 10% loss in refrigerant volume can result in up to a 20% increase in electricity cost to run your air conditioner.

What to Do in the Event of a Refrigerant Leak

If you suspect a refrigerant leak in your air conditioner, take action immediately. Call a certified St Petersburg air conditioning technician who can seal the leak fast. For any air conditioning repair you need, give Ierna’s Heating & Cooling a call!

Customer Service | Tampa | Ierna's Heating and Cooling

I have managed home installations (flooring and cabinets etc.) for over 15 years.  I would kill to have technicians and sales people as great as yours.

Tod in sales is outstanding. He kept his cool professionalism throughout the beating I attempted to give him over price. Even though you were not the lowest quote, Tod created added value by explaining the quality of work that you do as well as the professionalism he demonstrated.

 Your installers were great. Forgive me I don’t remember all of their names. Each one of them was polite, professional, and obviously very competent.

 Ron, you and your wife should be proud of the very solid business that you have built.  I wish you great success and will enthusiastically recommend you to others.

Air Conditioning Question: Does Humid Air Affect How AC Runs?

Monday, June 18th, 2012

You’ve probably heard a dozen times that humidity is removed by your Tampa air conditioning system. Unfortunately, the common assumption is that there is no inherent cost in allowing humidity to persist in their home. But, did you know it costs significantly more to remove humidity from the air with air conditioning than with a dehumidifier? Here’s why.

Water Vapor in Your Air Conditioner

Consider the amount of energy it takes to raise the temperature of water by one degree – one BTU. However, to change water from liquid to steam, another 10 BTUs are required. So, imagine how much energy it takes to condense water vapor from the air (in the form of humidity) into a liquid. This is what your air conditioner does whenever it processes humid air. It takes about 1,050 BTUs to condense one pound of moisture in the air into liquid.

The cost of running your air conditioner strictly for dehumidification can be huge, especially considering the fact that humidity is heaviest in the morning and evening when you probably don’t need your air conditioner every day (at least not early and late in the summer). Imagine, the cost difference if you used a dehumidifier to remove 150 or more pounds of moisture per week and an air conditioner when needed just to remove 15-20.

Negative Impact on How it Runs

Another thing to consider is that humidity can actually put an extra burden on your Tampa air conditioner. While the system is designed to remove that liquid from the air and get rid of it through the cooling coil and condensate drain, every extra minute the system is running is a bigger burden on it. Of course it will do its job for a few years, but the extra running time will add up, not only on your electricity bill but eventually on the machine itself.

The added pressure will result in eventual breakdown of the system and a need for early replacement. The easiest solution is to purchase a dehumidifier. These run at a fraction of the energy level of a full AC system and work extremely well to remove humidity from your home. In fact, most air conditioners will only remove humidity after 20-30 minutes of continuous operation. For short cooling cycles, you may not even dehumidify the house. So a dehumidifier ensures higher levels of comfort all at a lower cost.

Air Conditioning Tip: Why Replace Your Indoor and Outdoor AC Components

Monday, June 11th, 2012

Do you need to replace one of the main components of your split AC system in Tampa? If so, you are probably tempted to just replace whichever unit is failing in order to fix the problem quickly and cheaply. This is not always the best way to go, however. Here are six reasons why you should replace both the indoor and outdoor units at the same time.

  • Cost

Although replacing just the failing component – whether indoor or outdoor – will be less expensive up front, that choice often proves more costly overall. You will see just what that means in the rest of these reasons.

  • Advances in design

Heating and cooling technology is always advancing, so since you purchased your AC system, the products on the market have gotten quieter, more efficient and better overall. By replacing just the failing indoor component, you won’t reap all the benefits of this new technology, as the older outdoor component will still lag behind the times.

  • Higher efficiency

When both units are replaced at the same time, and with models that have the same technology, they work together more efficiently. That means more savings on your bills and a more comfortable home.

  • Matched system

Split AC systems are designed such that the indoor units are engineered to work best with a matching outdoor unit. When the system is matched, you get optimum performance and efficiency. By replacing just one component, you lose the benefits of that matching, meaning degraded efficiency and performance.

  • Warranty considerations

A new system means new warranty coverage. Replacing both units at once means a whole new warranty that covers your whole cooling system, so you won’t have to worry about paying for any more replacements jobs for a long time.

  • Wear and tear

Finally, think about the wear and tear your Tampa air conditioning system has undergone since it was installed. Maybe only your outdoor unit needs to be replaced now, but since your indoor unit has tolerated the same number of hours of use, it may be on its way out sooner than later. It’s like when you buy new tires for your car– you don’t buy one or two, you buy a whole set of four so that the whole system starts fresh. That way you only do it once, and not again in six months or a year.

For all these reasons, replacing both components of a split system is often the best and least expensive route to choose when facing a replacement. For more information about air conditioning system installation in Tampa, give Ierna’s Heating & Cooling a call today!

A Rave Review from San Antonio, FL

Friday, June 8th, 2012

Emergency Service | San Antonio | Ierna's Heating and Cooling“I started out on Memorial Day Holiday with my A/C down and Out . I called and Ierna’s was open for emergency calls . I couldn’t believe it because I tried 3 other companies and none answered . Long story short A tech came after a short wait . His name was Louis and he was clean .professional courteous and solved my emergency fast . His great service persuaded me to go ahead and purchase and schedule a New A/C system to be installed after the Holiday weekend . WAIT IT GETS BETTER . The installation crew were just as good and professional as Louis . I got a new Bryant system and I am very happy with its performance . John and Matt ( the installers ) were knowledgeable and extremely courteous. They were finished installing the system in 4 hours . To me this tells me how Ierna’s is managed from the top down. I will gladly recommend this company to all who asks.”

Air Conditioning Repair Tip: Causes of My AC Freezing Up

Monday, June 4th, 2012

If you have ever experienced a frozen air conditioning system in Tampa, you know the symptoms. The house is too warm. Water may be dripping from the ceiling. Sometimes you can hear the system running, but there is no cool air coming out of the vents. Ice and frost have built up in your air conditioning system, rendering it all but useless.

Yes, you may know what the problem looks like, but how about what causes it? Or better yet, how to fix it?


The most common cause of a frozen air conditioning system is a dirty air filter. Clean or replace the filter according to the manufacturer’s instructions. Turn the air conditioning system off, and just run the fan. This will help thaw the ice and get things running again.

It could also be that the cooling coil or evaporator coil is dirty. In this case, air flow will gradually decrease over time, but you may not notice until the system freezes up. If the coil is dirty, or if the system freezes again after replacing the filter, call a Tampa AC professional.

Low Refrigerant

Your air conditioning system is a closed loop, so refrigerant is meant to stay within the system without needing to be replaced or replenished. Over time, though, the AC system can develop leaks, which can cause freezing problems. Common culprits that can lead to a refrigerant leak include:

  • Friction against the piping
  • Open valves
  • Weak solder joints, or
  • Loose fittings

The only way to correctly diagnose and repair a refrigerant leak is to have a certified AC technician inspect it for himself.

 Needs Repair

Finally, the problem could be that some part of the AC system is defective, faulty or otherwise in need of repair. The blower motor or the attached relay may not be working properly, which can cause freezing. When this happens, professional repair is the only recourse.

Now that you are able to figure what is causing your AC system to freeze up, call Ierna’s Heating & Cooling today get it fixed, so you can stop dealing with the dripping ceiling and start enjoying the nice, cool air.
