    • I had the pleasure of having both Mat. M. And Hate D. Install a new HVAC system today. The did a great job. I work from home so while they were here I was working. They were both courteous and efficient and caused me very minimum interruption on my job. They also left the work area clean. Thanks guys!

    • In my 55yrs of experience with many properties and service persons,I have not encountered any persons more dedicated to excellent service. They performed additional work required to render the installation precisely up to current codes & provided additional accommodations for my health and safety.

    • Tom was here this morning for my yearly HVAC checkup. He arrived promptly, was extremely courteous, informed me of what he was going to do, explained the work he had completed, offered suggestions about filtration and duct cleaning, and set up an appointment. I highly recommend Tom as an A+ serviceman for One Hour.

    • Being a Comfort club member it was time for our fall service check-up and cleaning. We asked for Matt G Because he is our favorite technician. He is very professional and super nice. Does a great job and never acts like he is in a hurry. I really like dealing with Extreme One Hour heating because they are very honest and reasonable.

    • Alex was here today to service our air conditioning unit, and he did a great job. He was professional and friendly and explained what he was doing. We have been One Hour customers for about 27 years. We appreciate their professionalism and we can’t say enough about the service technicians and office staff. We highly recommend One Hour!!!

    • I have been using One Hour for about a decade. I have been very satisfied with their service. The technicians always wear their booties when walking on my floors and I appreciate that! They are very friendly and helpful.
    • We purchased heating and air conditioning units, which were promptly installed. The entire team from repairman to salesman to installation were extremely good. Everyone was very competent and professional, they knew their jobs and did them well. It was a pleasure to do business with them, highly recommend them.
    • called for service call on Friday morning; came at 1 pm. Decided to replace furnace unit; sales rep her at 3 pm.. Monday at 2:30, new furnace installation completed in less than 7 hours. Working great! service personnel, Fred and Jason, were prompt, extremely friendly and polite, and area was completely cleaned up. Best big install experience EVER.

    • Keith, Nathan, and Brandon did an excellent job installing our a/c and furnance. Didn't leave a mess and informed us on what we needed to know.. An asset to your company.
    • Nice work by Kenny. Arrived on time, took care to cover his boots when entering our home, got right to it, and finished in a very timely manner. This guy is a pro.
    • Terry came out and serviced our humidifier because it was leaking and causing the furnace to switch off. We have a yearly maintenance contract with them and he came out within a few hours and was professional, knowledgable, and fixed it quickly. We've had a wonderful experience with them. They're the Best!!

    • Andrew just completed our fall service. Everything is in order. Based on his report, he was very thorough. Andrew was very polite and considerate. Weather was terrible outside, and he made sure shoes were clean before putting on the shoe booties. See you in the spring.
