Parts of HVAC System Part 2

In the previous post, we wrote about the main parts of your HVAC unit. In the text below, you can read about the rest of them.


The compressor is the part of the air conditioner or heat pump that cools your home by releasing heat into the outdoor air, and it is usually installed outside. It cools your home by letting out heat into the outdoor air. To save energy and prevent problems with your HVAC system, you should keep fallen leaves, grass clippings, dirt, and other debris away from your condenser.

Evaporator Coil

The evaporator coil is part of the air conditioner or heat pump. It helps to absorb heat and lower temperatures in your home. The heat pumps work like air conditioners and have the same parts. Condensation on the evaporator and dirt and dust on dump coils can make some problems with the heat transfer process less efficient.


A thermostat has temperature sensors that decide when your heater and air conditioner will turn on and off. It is connected directly to your system through special wires. Some heating and air conditioning systems have more than one thermostat, and each thermostat controls a different zone. By this, you can save some energy by only heating and cooling specific areas in the house and choosing the most comfortable temperature. The best place for a thermostat in your home is away from stuffy zone or drafts, which can cause some problems.

We hope that now you understand the parts of your HVAC unit better. For more information, you can always ask our technician during his regular cleaning appointment.
