“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.”

“Very professional and courteous person. Very experienced in his job. Years ago we had to replace our furnace due to burst pipes in the winter time. During the furnace he noticed two out of the way locations (before the repair plumber arrived) where a water line had broke—he just did the repair and continued with the furnace installation. A definite factor in purchasing the new furnace from the same company.”

“Today, Jose came out because we had a river flowing from our furnace. Turned out to be a clogged drain pipe for the humidifier. He cleared everything out, dried everything, cleaned up everything and got everything working excellently again at a great price for an emergency service call! Been a customer for 20+ years and plan to continue to be for the next 20 years! Thanks so much One Hour Heating & Air Conditioning!”
