"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

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.
