Having your system regularly maintained by a professional will benefit you and your system in a number of ways. It will improve efficiency and performance, as well as substantially reducing the need for repairs.


Commercial systems are usually much more complicated than residential systems. Our comfort specialists have a thorough understanding of light commercial systems and how to care for them. If you’re in need of a new system, we can help with that as well.

When my furnace did I went looking for a dealer to purchase a new one. After a long search I found my self at George M Hills & sons. I did a quick request for a price quote. I was very quickly partnered with Tom who asked me what I needed and what I wanted. He then provided me with multiple quotes for compatible units that would do what I asked for. After careful consideration I decided to go with George M Hill and sons. Three days later I was having thg he unit installed by John and crew, they did a great job, the unit was professionally installed and looked and runs great. I highly recommend this professional organization.

My a/c unit outside fan stopped working yesterday (8-26-19) . The vents inside were blowing our warm air. I called GMH late afternoon. He called within 15 minutes. He was at my house within 30 minutes. He was courteous. professional and knowledgeable. He checked inside and then outside. The capacitor part was bad. He told/show me total cost which was a decent price. He had the part replaced and air running in my home. This was done within an hour. I am very pleased with their work and would highly recommend them.

Sold me my HVAC system originally. On two occasions, I have called for service and they have responded quickly and efficiently. Very pleased to date. Would give a 4.5 stats but the rating system doesn't allow it.

The company responded quickly to my call. I was able to get a service call when I needed it. They let me know when the man was on his way. The service man was prompt, thorough, friendly, and the price fair. I’ve had them out one additional time and had a very positive experience again. I feel like I have found an honest company to do business with. Couldn’t be happier.

Highly recommended. I got a same day appointment as a new customer. Very good communications about arrival time, and even a text with the technician's photo for my safety. The repair service provided was excellent as well.

Fast service response. The person taking the call was very nice and recorded the problem accurately. The repair technician, was very polite, knowledgeable, and professional, arrived at the scheduled time, and called well in advance to let me know he was coming. The repair was completed in the same visit. The price was very reasonable.

Great customer service. David explained what needed to be done and did a great job of taking care of us. Called when he was one the way. I would highly recommend there services.

GMH has provided my home with responsive services when needed for our two heating and AC systems. We have been overall pleased with the service, and the technician has been friendly and considerate. We had a little problem with replacing a thermostat without authorization (I already has the identical thermostat in my garage), and management said they would work to improve pre-authorization. This spring the annual inspection contract had a big increase in cost while at the same time ceasing to providing filters as a part of the contract. If a similarly large cost increase comes around next year, that would cause me to question continuing.

I HIGHLY recommend George M. Hill and Sons. We have used them for a number of years and could not be more satisfied with their customer support, service and quality of work.

I was very pleased with GMH Services. They showed up on time and did a great job servicing my unit. Everyone was very nice and seemed truly genuine. I was referred this company by someone 4 counties away so word of mouth has really spread the good name of this company. I will definately be using them for any future A/C needs or repairs.

We called George M Hill & Sons HVAC repair this morning after our HVAC unit woke us in the middle of the night dripping water through our ceiling! They responded right away! They sent a tech to our home within hours to help us. The gentleman which came to our home was courteous, kind, and was able to fix the problem. We are so extremely pleased with the service and competency of the entire company. We are going to have them service our HVAC units twice a year now and I would highly recommend them to anyone looking for fast, reliable, and courteous service! Thank you George M. Hill and Sons!

I am very satisfied with the service and professional service I received from this company. Highly reccomend them for any of your hearing and a/c needs. We just had a new trane unit installed with the new smsrt thermostat. Loving it. Also my 2 pound poodle loved the technician's. Love a company that is family oriented.

We felt extremely comfortable working with the George M Hill team. They listened to our concerns and did a complete survey of our existing system before presenting a proposal. I always received a text message prior to anyone arriving to work along with a photo. Todd contacted us after our job was complete to make sure we were completely satisfied. High recommendation.

As always George M. Hill & Sons is always professional and take the time to explain the problem with me prior to fixing anything. They make sure to speak in terms that I understand so that I know what needs to be done to fix the issues. We enjoy working with GMS.

I was very pleased with my service call. Setting up the appointment was easy and they kept me updated on when the technician should arrive. Danny was very professional and friendly and took extra time to explain to me the issue and gave me some options. He did not try to over sell me, but wanted me to be informed. Very pleasant experience and would highly recommend.
