“David (if I remember correctly) was very helpful and provided a quote for repairs that was very affordable. I also appreciate the way he explained things that felt like a person to person conversation rather than a conversation with a salesman”

“We needed some ventilation ducting replace due to animals who got into house and chewed up old ducting. Our Project Manager did a great job of coordinating repairs and the installation team did the work quickly and well.”

“Calvin from Duggan One Hour heating and Air-conditioning came to do a diagnostics on my HVAC. I will say he did a very thorough job and found the leak in my evaporator coil. Very impressed with the service that I received. Highly recommend.”

“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.”

“Once again, One Hour is excellent in executing their service contact. Josh did a great job of cleaning and servicing all three of my units. He further addressed any issues he found, and offered possible solutions to them. I really enjoy how thorough they are each time they come out.”

“Jacob did an excellent, thorough job. He didn't have the correct pump but went out of his way to get one today instead of coming back tomorrow. So now we can sleep in cool”

“Unfortunately, my technician wasn’t listed on the site. So I can’t mention him by name and I don’t believe he gave me his name. Can’t be too sure. Great service as always second time I’ve used this company hands-down the best. Technician was informative gave me every step that he was doing asked if everything was OK and to my liking. Worked with me around my animal and very clean will definitely be a repeat customer for the third time.”
