Get matched with top heating and air conditioning pros in Frontenac, MO

"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."

"The person who handled my call was friendly and professional. She told me a technician would be at my house in 4 hours and called me when he was on his way. The technician was outstanding, on time, professional, friendly, and quickly diagnosed and fixed the problem...best of all, he didn't try to sell parts/service that I didn't need! Best experience with an HVAC company I've ever had."

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

"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!"

"Extremely fast replacement heating and cooling installation. Exceptionally nice people. Zero problems after the installation of 2 Furnaces and 2 Air Conditioners in our zoned HVAC home."

"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."

"Seems I was spending a ridiculous amount of money on electricity because my central unit was not operating correctly. I now have flowing cold air."

"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."

"They had very good communication, and the worker was courteous and pleasant. He checked out my fridge and said I had to get a new fan. I called them back to let them know the ice-maker was still not working and they came back out. At that point, I was told the compressor was shot and I needed a new refrigerator. Ultimately, the took back the fan and only charged me only $56 for the diagnostic, and left me with a messy floor. I give everything an A rating except for the mess he left, which was slightly inconvenient in my condition."
