I had visitors coming from abroad so I needed my HVAC to work as soon as possible. AES (confusing…read morebecause I believe it's Antey in Google maps) offered me a free diagnosis and they told me that I needed to replace the HVAC machines. So I had given a thought and decided to replace it. I called them on Friday afternoon to make an appointment to install a new HVAC. They came the next day, Saturday, and finished all in one day! It's some kind of next level service that we don't usually expect in the States. My only complaint is that they installed a new system so that I cannot run the AC unit while my louvered door is closed -- I will need to somehow change the door later after my guests leave. Recommended! Otherwise, friendly company, fast service as promised, paid by credit card.

Comfort Zone Heating & Air (Kevin, owner) came to provide a solution. I saw his mind was occupied with nothing but solutions. Service, solutions, and more is what they delivered. We communicated via group text including with the office. I probably only called the office once, but got the hang of their system rather quickly. If we had immediate concern, Kevin would be on the phone call. We passed the city inspection in flying colors. HERS testing also. Josue and another guy came to replace all the old ductwork. Cleaned everything out. Very courteous. Very respectful with your things. Great value. Highly recommended. Include this company when you are looking for a quote. Thank you Comfort Zone Heating & Air. See you in the future for our maintenance.

And this was in August so I know all the companies were slammed!! Some companies wanted to charge me $100+ to come out for an estimate which would be credited towards the repair bill. Comfort Zone didn't. The repairman gave me a quote & went right to work. My A/C was fixed fairly quickly & the bill was less than what I was expecting - I hadn't gotten it fixed or tuned up for 10 years so I had no clue how much it would be & was expecting it to be high! The work was done well, repairs were explained to me & I hadn't had any problems. I would definitely recommend Comfort Zone Heating & Air! Trustworthy & real pros!

Found Emin on Yelp March 2026 when the upstairs AC suddenly stopped working, and Emin was there right away and was able to diagnose the problem, replaced a capacitor and got the unit working again. Then the downstairs AC wasn't cooling last weekend. Emin wasn't available so I called another contractor who took one look at the video of the furnace making weird noises and concluded the motor needed replacing, but that he couldn't find the motor anywhere, etc etc and it was such a hard push for me to replace the whole HVAC. After 24 hours of this hard sell on what was going to be the hottest day of the week, I took a chance and called Emin for a 2nd opinion. And miracle of miracles he looked at the video, found the part, and was at the property in 30 minutes. My final bill was a 10th of what the other contractor was selling me! Thanks so much Emin for being so honest and straightforward in a business that can be so full of scammers. You are a cut above!
