We have been with another "local company" for years for installations and service. On a semiannual…read moreinspection on 6/17/26 we were told that our 9 year old split units both had coil problems and repairs would exceed $13,000. Upon checking we discovered that this long time, local company had been sold to a national company/fund which acquires and then operates smaller local companies. We decided to obtain a second quote and Daniel from Hamstra spent 3 hours checking the systems and concluded it was in good working condition. We just signed up for a service plan with Hamstra and will be using them in the future. In our opinion the consumer needs to beware of upselling and if you question a quote obtain a second opinion.

Three AC companies rose to the top after a deep dive into online reviews - prioritizing quality equipment, excellent service, and fair pricing. Furthermore, my wife consulted online AI (ChatGPT) to see if there was something my manual searching might have missed. Sure enough, AI highly recommended a company I'd not even noticed - ComfortX HVAC. We contacted all four companies for quotes. Here are our best experiences among these companies (wherein 3 of the 4 were actually pretty good!): Initial contact & response - #1 = ComfortX On site jobwalk and Q&A - #1 = ComfortX Most appropriate system proposed - #1 = ComfortX Best overall price quoted - #1 = ComfortX Most expedient preparation & scheduling - #1 = ComfortX I know this sounds incredible, but it's all true. We were blown away that these guys could be THAT MUCH above and beyond their competitors, but this is supported by the fact that they boast nothing but solid 5-star Yelp & Google reviews. My point of contact was Matt, who happens to be one of the owners. Matt and his associate, Elias, were back out quickly to efficiently perform an outstanding installation in just one day. We could not have been more satisfied with the entire experience!

He used them for my sister-in-laws AC issues and they did a great job. Recently, our AC unit of 20 years plus started to die. We decided to reach out and book a service through them, and we were really pleased by their fantastic communication. Additionally, they were super professional, thorough, and provided all the information, steps of installation, and worked within our budget. I was especially impressed by the fact they used shoe covers when coming into our house. Installation day we left the house and entrusted them to install everything. It was a three person team and they managed to complete the job in four hours! They even cleaned up after themselves. We will for sure continue to go with this company for twice a year maintenance and repair! Highly recommend!

They found a slot in the schedule that they could guarantee a few days later, but also spoke with us letting us know they would try to get us in early depending on how other calls progressed, because we had no air at all. They were able to squeeze us in the next day! They were very friendly and responsive, called when they said they would, and addressed the problem very quickly. Most importantly, the service was amazing. They very very thorough making sure they looked at everything even once they found what seemed to be the problem. They fixed it wicket, gave some advice if it happens again and how to prevent it. They are very affordable and offer maintenance, which is helpful if you are trying to get a manufacturer repair by showing the system was maintained professionally. We have happily added them to our contacts for any future heating and cooling needs!

All communications are immediately followed up with an email, including receipts and quotes. They gave me a very readable and clear quote. Chris knows his stuff when it comes to construction in general which helps in building that quote accurately and correctly. Correctly? You might ask, well, he is the one and only contractor that wanted to extend the pad the HVAC was resting on and it was short by 3-4 feet. There were other telling comments that made me feel at ease immediately. They gave me a great discount for purchasing two units. (Yes, it is such a blessing most of the time to have two units, until you must purchase them.) Chris and his crew came out on the day scheduled. Note: do not set your clock by these guys. AM is AMish. Once they arrived, they were all business. They had both units installed with corresponding Google nests set up as well. At the end, they had everything cleaned up, nice and tidy. All done with friendly professionalism. Just a note, there are two ladies that live here. At no time did either of us feel uneasy. The crew are also animal people and work great around cats and dogs. Although, I did keep mine away, while they were working. I could not ask to work with a better company and people. Thank you so much!!!
