Get matched with top air conditioning pros in Plymouth, MI

"I contacted Greg after I turned on the heater for the first time and noticed a burning smell coming from the ducts. While they were booked out three days in the future, Greg found a way to work us into the schedule the same day. Within hours, they had the problem diagnosed and had located the parts needed to fix it--all at a fair and reasonable cost. Additionally, they offered advice on how best to maintain our air conditioning unit. I would highly recommend them and will be calling them again with future work."

"Very responsive to critical need to fix air conditioning during the heat wave. Courteous, friendly and professional. I highly recommend Harriman."

"This company went above and beyond. From the estimate to the install of both a new furnace and air conditioning unit quickly after the estimate. We had been without heat for 4 days in December in Michigan. Glad to sleep in a home with heat again."

"Work was professional and well done.  I did find one error on the humidifier installation and they came back the next day and fixed the problem.  The price was slightly higher than other quotes but these guys are great and a local company.  They offered 10 years on parts AND labor.  Will re-hire them again without questions.

"Excellent customer service from the first time Joe contacted me to the time Mike and his crew came to install new furnace and a/c units. One Hour Heating and Cooling was very affordable and was the only company I had to come out to give an estimate to identify an hazard with a pipe leading to the drain and the resolved it. Thanks to Joe and Mike educating me on the furnace and a/c units, they answered every question or concerns I had. I had 3 other companies to come out and was trying to replace items that didn't even need to be replaced. They were trying to justify their enormous prices and because of One Hour Heating and Cooling I didn't fall for it. I would truly recommend this company to anyone who is in the market for heating and cooling services. One Hour Heating and Cooling is truly about their customer's need and provide the best value."
