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.

Not because they told us about it or pushed it on us, only because I read about it on their website and thought, yep this is who I want keeping an eye on things. Honestly I can not say enough good things them. From what I can tell they are true and honest professionals.

We received quotes from 5-6 different HVAC companies, but Comfort Zone Heating and Air--and Kevin in particular--really stood out. Instead of just replacing what we had (which is what everyone else suggested), Kevin took the time to explain a newer system using a heat pump that he believed would be a better option. My husband did his own research and agreed--it was clear Kevin was looking out for our long-term needs, not just making a quick sale. Kevin and his team, including his son, were incredibly professional, friendly, and great to work with. They were the only company that included replacing all of our ductwork--and even redesigned it so our attic is now much easier to access instead of having to crawl awkwardly underneath it. They also worked around a lot of accumulated items in the attic and somehow left the space cleaner than when they started. While it wasn't the deciding factor, their quote was also very reasonable. We're so glad we found a company we trust not only for this installation but for future servicing as well. My daughter has also used them for a furnace repair and had a great experience. I highly and wholeheartedly recommend Comfort Zone Heating and Air!

I am so happy we found Robert Hall and Sons!…read more We had a very old, but still working, HVAC system. This summer, after going through our warranty company for a check-up, the technician ended up blowing our compressor. We then spent four visits trying to get the AC working again. It never did. Unfortunately, we realized too late that we had been completely scammed. While trying to get it fixed in August, we were also ghosted by another company right in the middle of a heatwave. Needless to say, I was stressed and overwhelmed. At that point, we decided to replace the entire system because we no longer trusted putting more money into repairs. That is when we called Robert Hall and Sons. Mike came out for an estimate, and right away, we felt like we were in good hands. He patiently answered all of our questions and, true to his word, we had a written estimate a few hours later. The estimate we received was beyond reasonable. After we submitted the signed contract, we were scheduled for installation about a week out. A few days later, I saw that another extended heatwave was in the forecast. After everything we had just gone through, I was not prepared to go through it again without working AC. I explained the situation to Mike, along with our HOA requirements, and he worked with us to make sure everything could be done as quickly, quietly, and efficiently as possible. His crew was amazing. They worked quickly, but thoroughly, and had the entire system installed in under three hours. I honestly could not believe how smoothly everything went. I cannot stress enough how professional Mike has been throughout this entire process. After the nightmare we had just experienced with other companies, it was such a relief to finally deal with someone who was honest, responsive, and did exactly what he said he would do. We now have a new HVAC system, a cool house, and peace of mind. Most importantly, we trust that if anything does go wrong, Robert Hall and Sons will be there and make it right. I would absolutely recommend Robert Hall and Sons. After everything we went through this summer, finding a company we can actually trust means everything.

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!
