  • I would recommend this business

Well, I search yelp and you all came through! Anthony arrive this evening, we were told it would be tomorrow due to the workload they were managing. It has been very hot the last week and I am sure we are not the only ones with a crippled A/C.

Anthony's arrival was a God send! He was professional, friendly, informative, and very helpful! He found the issue quickly and had us going in no time! He was also informative about how to balance the air flow in the House!!

Customer Testimonials

A/C was out on Memorial Day weekend (93 and humid). Extreme's came out very quickly, and got my house cooling again. It was recommend (not at all forced) that I change my system soon being builder grade at 16+ years old. After getting another quote, One Hour provided a better price for better equipment than the other guys. They provide payment options as well for any need. I have used them multiple times, and every time I call another HVAC company I wonder why I ever strayed from One Hour. Awesome group of guys (and ladies).


If you are looking for an honest company, Extreme One Hour Heating & Air Conditioning is the one! After having my yearly service on my furnace, by another company, I was told that I needed a very expensive repair so they gave me an estimate for a new one. Being a widow that has had bad experiences in the past, I decided to get a couple of estimates so I called Extreme One Hour Heating & Air. They sent John Seiber the Lead Service Technician out to give me my estimate.

After explaining my options he asked if he could take a looked at my furnace. To my surprise he told me that I didn't need a new furnace as there was nothing wrong with mine. Now I know why they have such great ratings for customer satisfaction! It's really amazing in this day and age to find a company that is this honest! Extreme One Heating & Air will be the only one that gets my business from now on!
Thank you John.


Have used Extreme twice in the last three months for different services ( A/C and Furnace )Great service. Was at my house in less than 4 hours !!! both times and charge was very reasonable. Definitely use these company if you what fast and reliable service.


I recently moved into a house that has dog hair in every possible nook & cranny and seemingly never had the furnace filters changed. I called Extreme about duct cleaning and it's the best thing I could have done for a fresh clean start! The guys were so courteous and efficient and really took their time to remove a mountain of the dust, dog hair, dirt, and even a few dead mice (eek!). They also did a sanitizing spray into each vent and my allergies say thanks!! I highly recommend Extreme and their air duct cleaning service if you haven't had your ducts cleaned in a while! It makes a difference in the air flow and quality of air!


I would HIGHLY recommend this company. The same day I called the company came out. Melanie and Diane (receptionist) were very nice and provided great customer service. Mike and Caleb came to my home to clean my dry vent and they did a WONDERFUL job. In doing the job, they were very professional and explained everything to me so that I understood what they were about to do. Please use them and refer them, you will not be disappointed.


I highly recommend this company they did an amazing job installing my new furnace . There customer service was absolutely incredible and very helpful with the questions I had . They also were very affordable.


Everyone at Extreme One Hour was very courteous and professional, and the tech was on site within about 1 hour of calling them early on a Sunday morning. Prices seemed in line with other HVAC contractors. He did replace my run capacitor, which was blown, only to reveal that the compressor was shot too, and I would likely need a new unit. Unfortunately, he couldn't uninstall and take back the $160 capacitor at that point, since now it was "used," albeit only once.

I understand he can't put a "used" part back on his truck, and it's not the tech's fault, but still, it stung. He offered to take it off the bill if I bought a new AC unit from him (which I didn't). I have a $160 paper weight now (that sells for only $10 on eBay or Amazon). I think the damage was the result of lightning, but the tech couldn't definitively confirm this so he didn't state it on the work order (which would have helped me with a homeowner insurance claim). But, I respected his honesty to not claim something he wasn't 100% positive about. I would recommend this company.


This company is top notch. We were quoted a very good price and they did exactly what they said they would do. We couldn't be happier with the service we received from their crew.


Quick turnaround, very professional. Great job on the ac and heat pump installation. Thanks again! We would definitely recommend.


This is the best company! I've always had great service and the system I purchased about 4 years ago has been very reliable. Today I had an annual PM on the system and I just have to say that Ben was absolutely the best! He was instrumental in troubleshooting a problem and went above and beyond. This is why I will always be a loyal customer because of your people like Ben. He deserves a big shout out and kudos!! Thank you so much!!


Excellent company. My tech Howie was extremely friendly and explained in detail the problem with our AC. We were charged a reasonable rate and we're very satisfied with our service. We definitely recommend this company to others. Thanks Howie for a job well done
