5 Main Air Conditioning Terms

When the weather gets warm we turn on our air conditioners, and once in a while, we have to face the reality that our cooling system is in need of a replacement or a repair. Repairing your HVAC system can be expensive and confusing, but Denver’s Best Heating and AC Repair wants to make this experience as comfortable as possible. We believe one of the ways we can remove the stress of HVAC repairs is by educating our customers. Consequently, this blog will share five main air conditioning terms you can expect to hear during a routine AC service call. Here are the 5 Main Air Conditioning Terms.

Air Conditioning

The first term you should understand is air conditioning. Most of us know our air conditioners to be the helpful cooling system that allows us to control the temperature and humidity of our home. This simple definition is easy, but important to grasp when working with an HVAC repair company.


It is easy enough to comprehend the purpose of an air conditioner. In fact, you probably do not need a working definition of the word, but when it comes to the mechanics and individuals parts of our air conditioners, definitions can become more useful. Take for example the word compressor.

Your air conditioner’s compressor is the component used to change low pressure refrigerant to high pressure refrigerant. It is common for your AC’s compressor to need repairs over time, especially if you do not regularly change your refrigerant.


Your air conditioner’s condenser also works with refrigerant, but its purpose is to change refrigerant from a gas to a liquid. It is imperative that your condenser is functioning properly or your air conditioner will quickly break-down, and fail to work efficiently. An annual maintenance check is a great preventive measure to take, to ensure your condenser is functioning well. Schedule your annual maintenance check with Denver’s Best Heating and AC Repair.


Contrary to your air conditioner’s condenser, your evaporator is designed to change liquid refrigerant to gas as it absorbs heat from inside air. This is an important part of your cooling system that should be maintained for your cooling system to function its best.


Most homeowners are likely familiar with their air conditioner’s filter, or at least you should be. Your filter collects debris and air pollutants keeping our air clean and healthy. A quick way to wear-out your air conditioner is by failing to regularly replace your filter. Change your filter regularly, following your AC manual, for a cooling system that functions its best.
