When you properly maintain your home comfort system it will heat and cool better, last longer, save money in operational costs and need fewer repairs. It just makes good (cents) to maintain your equipment. The current investment for a heating or cooling inspection is $119. We generally have a Spring & Fall preseason special at a promotional rate of $109.
Determining the proper size heating and cooling equipment for your home is of the utmost importance and should be done only by a qualified heating and cooling contractor. Properly sized equipment will operate more efficiently, dehumidify better in the summer, humidify better in the winter, last longer and provide you with a more comfortable indoor environment to live in. To determine what size furnace and air-conditioner you need for your house we must first determine the heating and cooling loads on the house.

We have been customers for 19 years, since the installation of a new HVAC system. We appreciate the preventative maintenance plan (spring air conditioner & fall furnace checks) to keep the system running well. Mark, Jonathan, and Mitch provide expertise and care for the equipment and are a pleasure to have in our home. (They even wear shoe covers inside the house!)

They took out the existing 140,000 BTU furnace and 2 1/2 air conditioner which kept the house remarkably comfortable and replaced it with a 80,000 BTU furnace and a 3 ton air conditioner. In the winter time we have to run space heaters to keep the back bedrooms warm. In the summer time the air would run only a few minutes and the house would be humid and uncomfortable, they came out several times and shut off a vent in the living room, slowed down the blower motor and set the thermostat to wait an extra degree before running; all in an effort to compensate for the 3 ton air conditioner which is too big for the house.

They refuse to stand behind their guarantee that their product will heat and cool the house to the customer satisfaction or be replaced at no charge. OH, HOW I WISH ID OF GONE TO ANOTHER COMPANY!

This company goes above and beyond with service. We have utilized their services for over 20 years. They always wear covers on their shoes when entering the home, wear masks during this pandemic, and leave home clean after servicing furnace. We just bought a new furnace and air conditioning system. We love the quiet furnace and it's nice a cozy in our home.

Comfort Specialist installed my new AirConditioner unit. I was surprised at how quickly they responded and completed the work. They did everything they said they would do; when they said they would do it. They were always professional and very easy to work with! Mark and his team took this daunting task for me and turned it into an "easy button" moment! The work was completed very fast and professionally. Thank you Mark and Comfort Specialist!

Mark & John did a great job. I used Comfort Specialist because they were able to keep my 32 year old HVAC Trane system running in the past. They always worked quickly & got the job done in a timely manner & it wasn't too costly. Which is why I chose Comfort Specialist. Putting in a new HVAC SYSTEM IS NEVER CHEAP, but there pricing was competitive with the competition. I am very happy with the results.

Comfort Specialists has repaired our system for several years and our experience has always been positive. When it came time to replace our HVAC, they were the first company that we called. Mark met with us to review our options and develop a quote. He didn't try to "upsell" us on anything, but let us know our options - including how much of our current system we could reuse.

We selected Comfort Specialists to install our new system and we couldn't be happier! They completed the entire installation in one day. They were extremely professional and took the care to protect our house as they brought in and installed our new system. Mark took the time to thoroughly review the operation of the thermostat, tell us how to get it hooked up online, and walked me thru the installed system, including how to find error codes should something go wrong. So far, we have been extremely happy with our system. The temperature in our house is much more even that it was with our old system.

Ridiculous price on parts for service. Replaced a blower motor on my hvac system and charged over $950. First quoted $690 but then tore it apart and realized it was a 1 hp motor instead of 3/4 hp. First quote of 690 had a price of $540 for the motor only. Looked up the price of the motor on grainger and it was a Chinese motor for $134. In other words the price of parts are 4 times what they pay for it.

Absolutely ridiculous! I voiced my concern about the price but the system was already torn Apart and its the middle of winter. I would look elsewhere if you have hvac problems in this area. I don't mind paying more for service but this is absurd.
