I had been using another HVAC contractor for years, but when he retired/relocated I began using Comfort One -- first, just for annual servicing. When my heating system broke down in the middle of winter, I called Comfort One, and they were here so quickly, and resolved what turned out to be a minor problem. Someone else could have taken advantage of the situation, since I sure didn't know what the problem was. Some time later, I eventually decided to replace my HVAC system, and got several quotes. Comfort One gave me several alternative systems to choose from (with varying prices and features) and didn't apply any pressure to go with the more expensive system. Their pricing was the best -- and my actual cost ended up being less than their estimate. They've also replaced my hot water tank. Competitive pricing, quick and reliable service, honest and thorough, and friendly. What else can one ask for? I really encourage you to give them a try. I am absolutely certain that you won't be disappointed. Steve T. read more

I have used this company to replaced my furnace and ac unit. If you are looking for professionals, honesty, customer service beyond excellence and a great price you can stop your search. This is a family owned company and they are amazing! Our hot water heater needed to be replaced and so phoned Rachell and she was able to fit us in and this is what they do. First Rachel is the best customer service person who will listen to your issue and never make you feel rushed. Josh and Mr Hamby are the other professional installers. They are kind, friendly and when they leave the area is spotless. Let's talk price. I phoned a well known company and they wanted over $6,000 and Comfort One gave me the same service for less than half and they will walk you through everything that they see you will need. Comfort is a family business and you will be part of their family as well. Give them a call you will not be disappointed and will feel COMFORT knowing that Comfort One Heating and Cooling will take care of you. read more

Our bedroom sits above the garage and the airflow was poor to the bedroom leaving the room hot in the summer and cold in the winter. Comfort One (Joel) came out on 3 separate visits. I thought I had to have an entire unit installed for 2nd floor. He determined that we had enough airflow for upstairs. When he looked at the builder grade duct work he spotted the problem. He moved the master bedrooms duct lead from the trunk to the top. That worked! Worked so well now my daughter's complaint has now changed. Well now her room (closest) to the trunk is not cool enough. Guess we'll call you guys back out. Thankfully, Joel installed a damper. Now with a twist of the damper, we can redirect some of the additional airflow. Very happy guys. You saved me thousands of potential dollars spent. read more

Comfort One has been the best experience for their knowledge, professionalism, and efficiency that I have encountered from almost any service that I've used. They came to the house multiple times after normal work hours (staying until 10 pm on one occasion) simply because it was, "on the way." They are great on the pocket book and they have phenomenal customer service. They will be my go to company for any air conditioning and heating, electrical, plumbing, or any other service they will be willing to do on my home and all future homes. Thank you, Comfort One for turning the A/C on for my family and me! read more

My AC stopped blowing cool during this wicked heat wave. I emailed Rachel Hamby to see if my unit was still under warranty and about my issue on Thursday night. She called me first thing Friday morning to see if Gary Hamby owner/operator/technician could come out between 10am and 11am to see what it could be. We had been experiencing many electrical heat storms, which blew the capacitor in the unit. Gary even topped off my Freon while there. I love this company as they are very professional and make you feel comfortable like part of their family. Annette Shipp @ LOW read more

This company has maintained and from time to time replaced the various HVAC systems, both at my old house and new. I rarely provide feed-back such as this, considering that good quality work merits good payment and that is that. However, time and again Comfort One has responded to maintenance and repair needs at my house, during the past 22 years, always graciously, by highly courteous technicians and with pricing specified in advance, so one has no shell-shock. I highly recommend this company for all HVAC work. G.D. - 2021-05-27 read more

We are so delighted that we have found Comfort One to do all the maintenance of our HVAC system and replace a water heater for us. We have lived in the Fredericksburg area for 2 years , and we have complete confidence in their expertise, and their prices are more than fair. We are just about to a remodel of lower level, which will involve redesigning some of our air ducts. Josh was so tolerant of all our questions, and made sure we understood the plan before he left. How refreshing to have found a company you can trust! read more

If you're in need call them, you won't be disappointed. read more

We have worked with Comfort One Hamby Services for nearly 10 years now and always found them to be friendly and easy to deal with, extremely competent, honest and forthright. Josh recently installed a new water heater and changed some things up for more effective operation and to make better use of the limited space we have for our mechanical equipment, taking time to carefully explain everything he was doing along the way. We trust all of our hvac and related needs to Josh and the rest of the staff. read more

They have been servicing our HVAC system for 5 years and I couldn't be happier. They are always quick to respond to any calls which really saved us when our old system went down in the midst of a very cold snow storm. They were able to install a new system in few days despite supply chain issues. I would highly recommend them. They are honest, quick responding and provide great service at a good price as well. read more

Comfort One provided quick, efficient, quality work in a professional manner. My installation took one day, taking out my old system to installing a brand new unit, inside and out. New wiring and conduit copper piping was run as well. My house is toasty warm this cold winter. I would highly recommend Comfort One to do your complete install from start to finish. read more

Fantastic to work with! When you call, you get someone on the phone quickly. They were able to come check out my AC the following day though my schedule couldn't accommodate, but we were able to do the next day. Gary came and was able to diagnose and fix the problem promptly and my AC is working well. Hands down, will call them again in the future. read more

ComfortOne installed a great new AC unit in our current home after we finished our basement, and installed central AC/heating and a new water heater in our previous home that only had window units and radiators. Both experiences were fantastic and I would definitely use them again in the future. Highly recommended!! read more
