“until after midnight before any real cooling took place. The humidity levels seemed too high. Jose immediately identified the issue and got to work rectifying the situation. He also showed us how to do some preventative maintenance that would ease the burden on our system. From the office scheduling through Jose’s visit we were thrilled with the fast, reliable service delivered by kind employees. We highly recommend One Hour Heating.”

“American Comfort and Ulises came to the rescue. Despite a favorable preventive maintenance call earlier in the month the unexpected failure of an electrical component created a loss of air conditioned air for our tenant. Ulises traced the problem to serial failure of a number of elements in the control and starting circuits of our HVAC system. He patiently inspected and replaced all elements of the system to isolate the problem which led to a complete revamping of the control system. He stayed well beyond the normal work day to make sure all would be working well before our medical office tenant opened the following morning. “Hats off” to Ulises and American Comfort. Other people and companies wouldn’t have been so dedicated to staying late and solving the problem.”

“Martin was thorough, patient and kind. He told me what needed to get done and took time to explain things in a way that was clear and understandable. He took extra time to speak to my husband on the phone to explain about a gas leak he found, which was not part of the maintenance plan we have, but still very important to address. Thank you Martin!”
