"The technicians are so nice and helpful, professional, and punctual. They've maintained my hvac for the three years I've lived in this house and all runs smoothly."

"They are always up front about my HVAC needs and explain things in detail before we agree for them to continue their work/recommendations."

"The gentleman that came out was professional. He gave me an estimate for the gas line and adjusted the water heater."

"A-ok! Dunn OneHour HVAC is always top notch!"

"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."

"Mr Mckenny was very professional. He brought everything he needed to repair the furnace in w/him, so he did not need to keep going to his vehicle for tools. I would certainly recommend him to my family, friends, neighbors."

"We chose Total Comfort Heating & Air Conditioning, LLC to replace our 40+ yr old HVAC system. The salesman (*Ken Ross) was knowledgeable and friendly. No hype, no sales pitches and no up selling. The Installers were punctual, pleasant, fast, and left the work area spotless. I would highly recommend this company to anyone in need of quality HVAC Services."

"Our house is 60 years old. We have lived her 42 years, this the first time we have had the ducts cleaned. The air in the house just seems lighter, the biggest thing is we have a black glass top entertainment center in the den. U could clean and 2 days later it was dirty again. We had this done2 weeks ago, it just now needs cleaning. We are very happy with the results. Would highly recomd it. Also vent centers is a filter company with wonderful filters for your air ducts. Ventcenters.com we put them in all our registers"

"Frankly, I rarely give reviews but this encounter warranted it. Here we go: On a 100 degree, sweltering Saint Louis afternoon, my 23 year old HVAC system finally called it quits. I knew I was looking at a full replacement and a repair would simply cost more money in the long run as the replacement was imminent. I did my due diligence and got multiple bids. I contacted John Hively and he said he could make it out that night (it was already 6:00 when I contacted him!) He showed up just 30 minutes later and did HIS due diligence checking all the components of the HVAC system before offering his diagnosis, verdict, and the cost of parts and labor. He was incredibly knowledgeable and his proposal was very reasonable considering the extent of the project and he was very competitive against the several other bids I had received - not to mention his warranties were unrivaled. Now, this is where the story gets really good... Because of the heat and my staying at a hotel because my house was 86 degrees, he rushed the appointment... While everyone else was giving a 7-14 day approximation, he was back the next day to drop of equipment and then the following day for the install. From 72 hours of making the call I had cool air again. He estimated a 4-6 hour completion time and his *extremely professional* crew was done in 5. They gave me a run-down on maintenance procedures, double checked everything to make sure the system was functioning as it should be, and were on their way. I can confidently state that John Hively provided the best residential service of ANY kind I've received since being a homeowner. I won't even waste time with bids on any HVAC needs again because Hively Heating and Cooling is my new go-to HVAC service provider. Do yourself a favor and call John. - A very happy homeowner"

"Local Air Duct Pros did an outstanding job! The team was professional, punctual, and very thorough. I noticed a huge difference in air quality right away. Highly recommended!"
