"Marcus is great. He's serviced my house several times for both AC and furnace maintenance. He's very knowledgeable and thorough. Takes time to explain things and answer questions. Also offers suggestions, but doesn't pressure you. He's very efficient. Appears to be an honest HVAC tech and good guy."

"I always recommend Anton's to family and friends who need HVAC services. Their prices are reasonable, and their service is top notch! All of their technicians are very professional and considerate and they don't try to sell you things you don't need. Ronan just came out this morning to do our annual A/C inspection. The service was excellent as always. He took the time to explain everything and made recommendations. I never felt pressured, and I trust this company to take care of my HVAC needs. They've got a customer for life!"

"They were professional from the phone call to the installation. He had everything he needed to replace the hot water heater and proceeded. I would definitely recommend Hosack Plumbing."

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

"I had them do a full HVAC replacement and it was done in about 6 hours. Great work and professional, always answers calls for any questions. I would definitely recommend."

"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."

"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"
