Get matched with top heating and air conditioning pros in Columbia, IL

"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"Very pleasant experience. I needed a new company and I was so pleased. They did an excellent job. Stains that would always come back after time have disappeared. So fast; so helpful!"

"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"My furnace was not working & the repairman came out on a Sunday morning & made repairs to keep my home warm until he could get necessary parts on Monday."

"I received 5star treatment from Ray Hiller, he identified the problem and solved it, I was up and running in no time.."

"They did a fabulous job in cleaning all the vents in the house. The entire crew was very professional and treated our home with care. Even our dog loved them! We highly recommend using them!"

"Furance was not working, call House Doctor. They were out the next day and got it back up and running. Professional and efficient. Plus, very affordable."

"Vinc and his crew were exceptional in the work performed and their interaction with us. There were at least seven guys here and they were all friendly and polite. The site manager Kane is exceptional. The best that I can say about this company is I plan for them to do other work for me on near future."

"Prompt and professional service. I was impressed."
