Maintaining your HVAC during the dog days of summer!

Let’s talk about the effects of not maintaining your unit and how our AC maintenance could have prevented a hot office on a hot NYC summer day!

First, we need to understand the basic idea of how an air conditioner works. Don’t worry we’re not getting too technical! Air conditioners are nothing but a heat exchanger. It removes the heat from your home and moves it outside via the freon. In order for your AC unit to do this it MUST breathe the air, and lots of it! That means the filters must be clean and kept clean all year long. The cold air that your air conditioner is blowing out of those vents comes from the air that it sucks in though the filters. In other words, if the filters are clogged, your AC unit cannot breathe well and is certainly not performing efficiently. So change those filters every thirty to forty five days.

That part of AC maintenance is your responsibility. It is very important those filters are clean so your air conditioning unit can cool you off on those 90 degree days! Now let’s go out to the other side of this breathing behemoth, the outside condenser unit. This part of your air conditioner has just as big a set a lungs as your inside unit! It needs to breathe lots of fresh clean air to cool off that hot freon coming from inside your office. The only way it does this is by pulling air through those fins or grill.

When your AC unit was engineered it was designed so that it would work properly only if EVERY square inch of the coil is clean and available to remove the heat from the freon.Throughout the year, pollen season, mowing the yard, and dry dusty days produce tons and tons of dirt particles clog up that outside coil. Folks, you have no idea how dirty that thing is! Unless you have cleaned that coil with a high pressure washer and the specialized soap, that coil is so dirty it would probably make you sick to see it washed out. A dirty coil can not efficiently remove the heat from your home but the problem gets much, much worse on these super hot days in NYC.

Coils
Here’s where I’m going to get slightly more technical but it’s not hard, so follow along;
As we all know heat is the destroyer of all, it breaks down matter. The compressor in your air conditioning unit could be considered the heart of your HVAC because the compressor pumps the freon through the system. Your compressor is a large pump made of mechanical parts and electrical windings, something heat loves to destroy. Inside your compressor there is a heat limit switch that will shut you compressor off if it gets too hot. Following me so far? Told you this was easy!

So, on these super hot days, if every square inch of that outside coil is not available to remove heat from the freon, the freon will not be as cool as it needs to be as it passes through your air conditioning system. The freon will get warmer and warmer until, not only does it become ineffective but it can not cool down the compressor and the compressor will shut off because it is too hot. The air conditioning compressor will cool down after about an hour or so and turn back on till it gets hot again, then shut down again. It will continue that cycle until……. #Guardian24 /7 #HeatWave   #GuardianHVACSpecalist services your HVAC!
