-Monty V.

"If anyone is needing a great air conditioning and heating company that is reliable, honest, and responsive, this is the company for you!! They have been taking care of my equipment for 30 years, I know the family and you can't find any better in town. Do give them a try!"

"First experience with King air, very professional techs, not trying to up sell you on product. Prices are reasonable and they have the experience you are looking for. Geothermal experts!!!"

"Your technician could not have been more polite and respectful!!! He wasted no time in getting down to business checking my equipment. An issue was found and he explained it well enough for me to make a quick decision to do the fix before the motor failed. Your cost is reasonable too. You definitely are my HVAC company of choice!!!"

"Jonathan was on time and very friendly. He explained the condition of our equipment and the service work he did to insure proper operation of our AC system. He tested the AC to make sure it was working properly before leaving and told us to call if we had any questions or problems later. Excellent service overall."
-Gary & Janice A.

"My technician was very polite and professional. He took his time and explained everything that he was doing. We would welcome him back."
-Vince & Cynthia I.

"Excellent, professional, and courteous service. My AC went out on moving day and King responded promptly, working me in on a Thurs/Fri before the holiday weekend. I have been using King for years and have always received outstanding service from the office staff and the technicians. Thank you."
-Mary Ann T.

"King installed our furnace nearly 10 years ago and has been routinely servicing the unit with no problems at all. They are very good at what they do and are very professional."

"Quick to give estimate, then quick to schedule to do the job. Hard workers that were respectful and informative. And the price was lower than expected. Great honest company. Would recommend to anyone."
-Bill T.

"The service team Austin and Will have both helped me before. I hold them in the highest regards. They both are like good neighbors. Treats me like family! I mean they will go that extra measure. That means a lot to an old lady. I trust them to be the experts. I thought there was a serious problem with my furnace and was prepared for the worst. They went threw everything. Even removed the flue, got on the roof and was able to assure me nothing was broken. Something had caused an over heating condition and tripped the sensors to shut down. Could have been dust matter falling down the flue. So they cleaned it out real good. I'm just relieved they went to that extra measure. No one had ever taken the flue apart and cleaned it that way before. Will said that was probably going to take care of it and no need to change parts that were ok. See what I mean! These guys are good people, they just want me safe. Thanks King Air and Heating for hiring the BEST."
-Pam B.

"We appreciated the quick response time and the fair evaluation of our problem. Your office assistances are always courteous and polite. Your repairman was also very courteous and considerate, even driving back to the office to get a heater for us to use. I am sorry that I did not note their names, but please extend our thanks to them. We have been with King for a long time and plan to continue to do so in the future. Mike, appreciate your prompt and informative visit." 
-John & Elizabeth K.

"I had to call King early in the morning on New Year's day because my elderly Mom's furnace was totally out. It was one of the coldest days of the year, I was afraid that I would have problems getting somebody out there that day. King was awesome. They arrived very quickly, fixed the problem and had full heat blasting in no time. They kept my Mom from having to leave her house. The service guy called me with a complete description of the problem and fix and then emailed me the invoice, which also contained a detailed description. I was able to pay them over the phone so that my Mom would not have to worry about what to do. Thanks to a wonderful company that we have used at multiple properties over many years!"
