“I have been dealing with this company for about 35 years with never a downside.”
“Keith and his team are amazing! I called in my issue at 6:30 AM and they arrived and fixed my system before most other businesses are even open.”
“We chose Clark Heating & Cooling because of their ability to meet our needs. Some of the bigger companies treat you like a "project number" Clark offers a personalized experience and treated us as a valued customer!”
“Everyone we worked with was great! Andy was able to come out next day to recommend the best solution for our 100-year-old house which had some challenging design constraints. Communication by email and phone was spot on. Installation happened just days later.”
“Clark Heating and Cooling originally installed our Furnace and AC in 2003. They have always provided us with excellent service. I always feel comfortable knowing that they are selling us exactly what we need, and not something that we don't.”
“Keith and the team were amazing. They fixed a nonfunctioning boiler system that was poorly installed, were clear and transparent about their pricing, and exceeded our expectations by a mile. Thank you guys!”
“Could not have been a better experience. Installed a replacement air conditioner and furnace on the hottest September day since 1904. Topped out at over 90. My hat is off to Jake, Doug and Nathan. Very efficient, helpful and pleasant. Did a couple of things not on the order, just because they needed to be done. Really nice.”
“I can't say enough good things about my experience with the whole team at Clark Heating and Cooling! From my very first call with Joleen, the communication was prompt, professional, and incredibly clear in explaining everything I needed to know…”
“Our furnace went out on us and we needed a new unit quickly. Keith came out to our house the day he got back from his vacation. He did a wonderful job giving us our options… After they were done, Jason stuck around and gave us an in-depth walk through of our new thermostat.”
“Keith was very informative and took the time to explain everything to me. It was obvious he was not there to up-sell me on things I did not need, and carefully assessed what would work best for my house and family.”
“My AC went out last Friday. during this first heat wave of the summer, I called Monday morning for service and they sent someone out by 11.30 a.m. My system was shot. By today, Tuesday, they have installed a new one and I have AC. Best customer service I have had in a long time.”
“I called Clark Heating and Cooling on 11/12/2017 as our furnace was not working. A service guy came out and said we needed a new furnace. My husband talked to the sales person Keith Comstock and the next day Tyler and Doug were at our house to install our new furnace. I highly recommend Clark Heating and Cooling.”
“They did an awesome job. Very responsive. Every employee we interacted with whether in person or on the phone was very professional, personable and wonderful to interact with. Our family will most definitely be using this company again when needed.”
“Great to work with. They were efficient and knowledgeable.”
“Excellent service.”
