As a homeowner in Bensalem, Pennsylvania, the best way to make sure the HVAC system in your home remain in good working condition is by understanding how it operates. Even if you can’t maintain or fix the HVAC system on your own, you will be able to recognize when it needs maintenance or repair. If you’re willing to learn how your HVAC system works, this brief guide goes over the major parts of your air conditioner.

The Compressor

The compressor, which is typically a part of the air conditioner’s outside unit, is responsible for changing the pressure of the working gas. While working fluid will enter the compressor in the form of low-pressure gas, the working fluid leaves the compressor in the form of hot, high-pressure gas. The compressor does this by forcing the working fluid’s molecules to become closer together. The compressor then transfers the high-pressure working fluid to the condenser. Routine checks for the compressor should establish that there are no broken capacitors or broken valves.

The Condenser

The working fluid enters the condenser as a warm, high-pressure gas. All air conditioners feature metal fins, which work to remove heat quickly from the high-pressure gas. Therefore, once the gas leaves the air conditioner’s condenser, it will be much cooler in temperature. The biggest change that occurs to the working fluid in the condenser is that it converts from gas to liquid. The working fluid is funneled into the evaporator through a small hole. During routine inspection, check for leakage and damage to the metal fins.

The Evaporator

In the evaporator, the pressure of the working liquid starts to drop. This causes the working liquid to evaporate back into a gas. To become a gas once more, the working liquid needs to use the heat from the air around it. As you check around the evaporator, ensure the cleanliness of the evaporator unit and the fan.
