"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"The technician Adam couldn't have been more professional and helpful. He arrived on time and was very courteous. He quickly was able to assess the problem and repair it. I'd recommend One Hour Heating and Air Conditioning to anyone looking to install or repair their HVAC system."

"On the price, I don't, but it was also reasonable. They had also installed a water heater like a year before, reasonable. For sure they're a good service provider, any issues I have with the HVAC or my water system, I'll go to them. They clean up behind themselves; I don't have to do much."

"APT Heating & Cooling (Greg) was extremely prompt in answering our request and scheduled us for a few short hours later. He was very thorough in reviewing our problem, was clear in explaining the problem, and offered recommendations without pressure. He was very personable and seemed very knowledgable. We would recommend this service to others and would use APT Heating & Cooling again in the future."

"We had a central air conditioning installed in our 55 year old home (replaced 3 Sanyo zone cooling units.) It was installed in our attic with ducts in the closets to the first floor. From the first phone call, to the salesman coming to our home, installation, inspection, and a service call, everything was wonderful! Very professional, knowledgeable and courtesy. So grateful to Home Advisor for matching us with All Seasons. Keep up the great work!"

"Bryan serviced our heater, he also told me about the condition of our heater. What it would take to repair it & that the age of the unit would make it too costly to repair. We appreciate your quality work & your advise, thank you."
