"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!"

"Great. Brandon knew his stuff. He conducted and airflow test to show us where our leaks were. He provided suggestions on where we could best reduce leaks. He also looked over our structure (joists) and HVAC system, again, suggesting improvements. Well worth the investment!"

"MCS techs were very courteous. New HVAC system install went well. They explained all their work professionally. Also found a crack in the flue and replaced which was overlooked by a previous contractor. They are very thorough and reasonable. I highly recommend MCS."

"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."

"Liberty did a fantastic job identifying and rectifying airflow problems with our existing Hvac system that was installed less than two years ago by another company. They were punctual, responsive and incredibly knowledgeable. I highly recommend them."

"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."

"Bernie went above and beyond to help us get our HVAC back up and running after a lightning strike damaged it. He saved us a ton of money and provided excellent service. He is also a excellent communicator and educator on all things heating and cooling."

"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."
