The compressor is one of the four basic parts of an air conditioner. The system works by replacing warm indoor air with outdoor air that has been cooled by a refrigerant. When air coming from the vents does not feel cool, it could indicate a problem with the compressor.

AC COMPRESSOR
How Does a Compressor Work?
Air conditioner compressors must maintain a consistent pressure level, use the correct amount of refrigerant, and release pressure safely if necessary. Refrigerant is a liquid or gas that cools system air before it is released into your home. The compressor starts the cooling cycle of an AC unit by drawing the refrigerant from inside the home and pressurizing it so it heats up.
The compressor pushes the resulting substance to the condenser coil. This apparatus pushes the gas out of the unit, where fans cool it. This extracts the heat and transfers it out of the home. After the heat has been extracted, the refrigerant is pressurized into a warm liquid that passes through a special valve that removes pressure and heat. This liquid enters the evaporator coil and becomes a gas that enters the home to cool its ambient air.
What Are the Different Compressors?
A home AC unit will likely have one of these four compressor types:
- Rotary compressors: Inexpensive and long-lasting, these are less efficient than other options and are most commonly used in window units and some central air systems.
- Reciprocating compressors: An affordable model found in split-air systems, but may not last as long as durable compressor models.
- Scroll compressors: A more efficient model found in high-end AC systems that has a long lifespan but is on the expensive side.
- Variable speed compressors: The most expensive system, but also the most efficient and durable.
Is My Air Compressor Broken?
When an air compressor needs to be repaired, the homeowner may notice strange sounds coming from the HVAC unit. Rattling, clicking, or rumbling sounds are causes for concern that should be serviced. Other signs of a compressor issue include leaking refrigerant fluid from the unit, blown fuses when the AC is running, limited airflow, and air that feels warm rather than cool.

Carter from American Energy exceeded my expectations for a standard inspection. He left our HVAC system looking bright and shiny! He called before and was able to come by early. Really appreciated that!
Greg Rangel was on time, gave me a courtesy call before he arrived, and once he arrived, he called to find out the issues with the AC and got to work. Greg provided me with information about the AC unit after he found out what was happening, and he walked me through the process and the cost! He also changed the filter! I am now a member due to his outstanding customer service. Thank you, Greg, for your professionalism.
This company responded immediately to address an air conditioning problem for my elderly Mother during 100 degree heat. They responded in just a couple of hours. Greg Rangel was the technician and fixed the problem. He did explain the unit was older and would soon need replacement. He thoroughly explained this to me and offered a senior discount for my Mother and a lower priced unit. Job well done and thank you.
Technician conducted a thorough inspection of the HVAC system while maintaining a friendly and positive demeanor.
I recently had an air duct cleaning and I am very happy with the results. The team was so knowledgeable and personable. I would use them again for this or other HVAC needs.
Quick scheduling and professional service. I will use them again and again. Thank you!!
Great A/C service by Garrett. He was very thorough and knowledgeable on his service. Would highly recommend.
Truly professionals. Garrett showed up at scheduled time, answered all my questions and did a thorough inspection of my unit. Never felt pressured or like I was trying to be sold on anything. He explained everything along the way. An issue was found on some wiring outside, I was shown the issue and given the option to have it fixed. He showed me the completed work and the material used. I would highly recommend this locally owned and operated company.
Greg arrived late Saturday evening and worked out the problem. He explained the problem and eventually determined it began with the original set up of the thermostat, which was wrong for a heat pump. The problem was fixed, and great credit to Greg for being enthusiastic, professional and staying until it was done.
We have had a great experience with everyone from American Energy. Today we had David, and he is a very nice young man, respectful, knowledgeable and very professional. I would recommend this company to all my friends and family.
