This company is amazing! They are very prompt, professional, knowledgeable and efficient. Unlike other companies, they are in business to serve their community and not to pad their pocketbooks. I have used them twice and both experiences put my mind at ease and fixed my problem quickly. I highly recommend Comfort First!

I can't say enough about how amazing this company is! Not only were they incredibly responsive in the brutal heat, they worked with our schedule and were sensitive to some personal challenges we were dealing with at the time. We replaced our furnace and got our a/c going all for a very affordable price. The guys were very friendly and professional and I was totally comfortable with them in my home.

We have three pitbulls and they took time to play with the dogs so everyone was comfortable and at ease! We didn't have to crate them or keep them outside. That means a lot to us! Definitely give these guys a call first!

Called them about 1 1/2 weeks ago regarding a quote for anew furnace/ air conditioner. The owner come to house and gave a written quote. The quote was accepted. Set an installation date for today(6-18-2018). Today is the hottest day of the year. Two workers came, immediately got to work, explained everything to me, I also asked a lot of questions and they answered them. The job took about 4 hours. Owner showed up at the end of job. Very, very professional company and workers. Sorry, forgot workers name, they did introduce themselves. Highly recommend this local business!
