Know Your AC Unit: Air Conditioning Facts

by | May 8, 2017 | Air Conditioning, HVAC Maintenance

HVAC systems are much like cars – the more you know, the better you can take care of them. AC units and furnaces often get overlooked in general home maintenance since they are mostly out of sight and run behind the scenes.

Let’s look at a few things about your AC unit that you may not know:

An Air Conditioner Doesn’t Create Cool Air

What happens in the process is actually the removal of heat from the air. Your AC uses a chemical called refrigerant to remove heat and transfer it outside. The warm air runs through the lines and coils in your unit, and goes form liquid to gas and back again. In this process, the refrigerant removes the heat and transfers it elsewhere so that when the air comes out the other side, it is cool.

Your AC Will Remove Humidity

Lower humidity helps the overall comfort level by making you feel cooler, even if the temperature is the same.

Your air filter needs to be checked and replaced every 3-6 months (depending on manufacturer’s recommendations.) A dirty air filter restricts your air flow, which reduces efficiency, costing you money. Over time this can put stress on your unit and could lead to a costly repair.

Maintenance, Maintenance, Maintenance

Just like a car, your HVAC system needs regular check ups to keep it running in tip-top shape. Having regular annual preventative maintenance will bring your system longer life and fewer breakdowns over time.
