One AC Myth You Should Never Believe

Monday, July 13th, 2020

woman-looking-surprisedYou may hear a lot of advice over the years on how to boost efficiency and performance for your air conditioner. Some of this advice is worth listening to—investing in professional maintenance for your cooling system, changing your air filter every 1-3 months, clearing out the space surrounding your outdoor unit—and some is, well, not.

For instance, have you ever heard from an HVAC “professional” that your air conditioner’s refrigerant is something that needs to be refilled on a routine basis? Unfortunately, they may be telling you this because either they actually believe this is the case—meaning they aren’t actually a trained and experienced professional—or they’re trying to get more money from you.

The one AC myth you should never believe is that your refrigerant needs to be refilled, what we call recharged, every maintenance session. Read on to learn what’s wrong with this concept!

Pittsburgh, PA Air Conditioning Repair Tip: Spotting a Refrigerant Leak

Monday, July 15th, 2013

The level of refrigerant that circulates through your compressor, coils, and expansion valve is vital to the effectiveness and energy efficiency of your air conditioning system, no matter what type it is. You simply cannot expect your home to stay cooling during the summer months without the correct refrigerant charge. In today’s post, we’d like to examine this issue a bit more closely.

Because your system does not expend refrigerant during the cooling cycle, there are really only two reasons why it is low. Either it was not installed with the correct amount of refrigerant to begin with, or it has developed a leak, due to either a puncture or corrosion. Let’s take a look at a few signs indicating you may have a refrigerant leak:

  • Inadequate cooling: One of the most common indications that you have a refrigerant leak, and thus low levels of refrigerant, is inadequate cooling. If you recognize a drop-off in your system’s ability to keep your home cool, then it may not have enough refrigerant to complete the cycle effectively. .
  • Warm air: If you feel warm air coming through the ductwork and you’re calling for cooling, then you know something is not right. One of the causes behind that warm air could be low levels of refrigerant. Your condenser coils simply cannot be effective if there is not enough refrigerant. Likewise for your indoor evaporator coils, which are responsible for cooling your air.
  • Hissing sound: Do you hear a hissing sound at or near your AC components? If so, the sound you might be hearing is not air but gaseous refrigerant. Not only is this harmful to the environment, but it can be devastating to your cooling performance and energy efficiency.
