One Hour Heating & Air Conditioning® of Wilmington De

Mike was extremely friendly and professional. Appreciated that he explained everything in details and provided options. He had lots of patience with all my questions. Thank you Mike for your service today and will definitely call One Hour for all my future needs!

Checked my aging heat pump system and confirmed that everything was working as it should. There was no high pressure sales implemented by Mike my technician. He was just very through and honest about the state of my system, which was much appreciated. My experience with this company was very positive.

CJ exemplified the highest level of technical skill/expertise and customer service while addressing our HVAC needs. He was prompt, courteous and able to readily diagnose and address the issues with our system. We will call One Hour again when the need arises and highly recommend its service to our friends and colleagues.

Great experience.The team was excellent. The old boiler was replaced very professionally. Now we can enjoy our holiday weekend without any worries. We signed up for the maintenance plan too trusting we will be taking care of. B/R

The system was just inspected in Nov but was making bad noises in Jan. I called for service and got an appointment in 2 days. While it was more than I wanted to pay( is any amount good?) I feel sure the problem was fixed and suggested improvements will only enhance my quality of living and hopefully be more financially beneficial against ridiculous power bills. Thank you to Arjay for being thorough, friendly, and a very good salesman.
