    • We've used One Hour Air Conditioning & Heating for a number of years now and have always been satisfied with the work performed by their service personnel. This is the first time that Larson has performed the maintenance service on our system; he is very good. He's thorough, careful, clearly answers questions you may have, and he provides descriptions of probable future maintenance tasks. In addition, he's courteous and takes related COVID-19 issues seriously.

    • I am very happy with this company, I look forward to doing many years of business with them. So far each employee has treated my home as if it was their own. In this day and age that kind of pride in workmanship Is extremely rare. I am so glad I found this company.

    • Air conditioning was out. Called and they came out a few hours later. Quick diagnosis and solution.

    • Jonatan and Osman were an excellent team to install the steam humidifier on a recently installed HVAC system. The two are friendly, professional, and thorough. They respected the home environment. Their work, clean up and final product are a work of art.. Couldn't ask for a better team. They understood the complexity of the installation. They went thru it without any issues/problems. Was even able to test the humidifier is in working condition. Both are thorough professionals.

    • Larsen Kimble called in advance of arrival. He was on-time. He was friendly and personable. Also very informative and explained everything he did. He wore shoe covers in the house and a mask at all times. I have been doing business with One Hour for more than a decade.

    • We are in the process of having a new Air conditioning and heating system put in so far the process has been very professional and quick. Our new system will not be put in until next week however they brought over portable units to make sure we are comfortable until they get the work done. In this day and age that is unheard of I would recommend this company highly

    • I appreciated the care Brian took to diagnose problems with two different systems - we found multiple issues and he objectively gave me options without trying to sell me anything. I had a lot of confidence in his assessments and would be happy to work with him again

    • Austin provided expert, professional service and explained the work performed. I am extremely satisfied with One Hour Heating and Air Conditioning.
    • This furnace is a God send. Last year I had to keep it at 74 just to keep reasonably warm. My bills ranged from $15 - $160 each month. This new furnace I keep it at 70 and it's warm. And my bill this month was $27. WOW, what savings. I will recommend your services and equipment for everyone.

    • I thought that it was going to be a mess (getting ducts cleaned) but they were very neat and professional and they had taken their time to do it right. Well done and I only wish I did it sooner.

    • I had them come to fix a leak from the PVC pipe that goes from my furnace to the laundry tub to drain the water from running the AC. They gave me an appointment the day I called and were on time. The repairman wore booties over his shoes to not get my rugs dirty. He was very polite and knowledgable and did a great job fixing the drain pipe. He also changed my furnace filter while here. I would use this company again! The price was reasonable.

    • The two companies have always provided outstanding service and the technicians are professional. The service contracts are great and I have recommended One Hour and Benjamin Franklin to my neighbors.

    • I have been working with One Hour Air and Heat & Benjamin Franklin Plumbing for years now. Most recently they changed a filter at my home. I will stick with them and would recommend them to others because they are very good at keeping to their schedule and being responsive. Their workers are professional, clean, and, they respect your house and you. Their pricing is fair and I think this company really has quality people.

    • It was our first time using One Hour Air and Heat and Benjamin Franklin Plumbing and we are very satisfied with the quality of work they provided. Most recently we had a motor replaced on our heat pump because we were having some issues with it ever since we bought it. Everything works great now and the process was very smooth. The employees were very respectful and they cleaned up after themselves. They also did a bit of preventative maintenance before they left so that we could avoid future problems easier. All the work they did was under warranty so all I really had to pay for was the labor hours which wasn't bad at all. I would definitely recommend their services to anyone, and will be using them in the future if anything comes up.
