“We have 3 heating/cooling zones in our 2300 sf home. We were having some temperature discrepancies and frankly, we weren't sure what areas were covered by each thermostat. We called One Hour Heating and cooling. Jordan came out and evaluated our AC unit and our furnace. He found a couple of issues and explained each zone covered by each thermostat. He was fantastic. Jordan educated us on how our system works. I use the word educated because he explained everything very well was not pushy and was very polite, personable and professional. We had him do the work he recommended at a very reasonable cost. We will definitely be using one hour heating and cooling for our future needs.”

“Very Happy with the service we received. My moms airconditioner died in the middle of the night Tuesday morning, they were there around noon the same day and a brand new air conditioner was installed by 11 am Wednesday! They understood my mothers medical needs and how important getting her air was. They clearly gave us multiple options and made the whole process easy. Thank you so much! Highly recommended!”
