"My a/c hadn't worked for two days, it was 90 degrees in the house. our go to hvac company is comfort heating and air, we called them, and a gentlemen named Taylor Burton showed up and promptly got to work. He was able to fix the issue within 10 minutes. He told us what was wrong, and even changed the filter to the unit. I highly recommend this company. I've used them before for my hvac needs, and both times they were able to fix whatever problem I had. 5/5 stars."

"Extremely professional and thorough. I was delighted with the service. Two other HVAC companies had tried and failed to fix the problem I was having. Lucas quickly identified the problem and solved it with minimal cost. I would very highly recommend this company. NOTE -- cost of service represents only my out of pocket cost through my home warranty service.

"We had recently purchased a home and had reason to be believe it had been some time since the HVAC was serviced.  Aire Serv came out and performed a cleaning and inspection of the system.  The technician was punctual and polite.  He did a good job and fixed a minor leak we had in the condensation line. 



They offered some recommendations for improvements, but did not try to upsell us on anything.



We will be using Aire Serv again.

"This is a great company and I am glad they are around. Extremely professional, detail oriented, hard working and honest. I needed to replace my ancient HVAC system and I was fortunate to have had this company help me with that. I ended up with a couple of bids for the same brand and model and Comfort Zone gave me an honest price which was thousands less than a competitor (Again, same brand and model number). Equally important is that they know what they are doing and they do the job right unlike many of the less knowledgeable competitors. Honest, knowledgable, hard working, great to deal with! They have earned my business for sure."

"The office people were nice very and responsive. I needed installation in a hurry and they scheduled me promptly. The technician wasn't too friendly but he did the job. I had to ask alot of questions because he wasn't forthcoming with any information. Other than that I would definitely use them again. Since I am a member of The REMC, I didn't have to pay Greenwell anything, It was all done through my electric company.

Heating and Air Conditioning FAQs, answered by experts

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance
