"2 techs came out a week ago, serviced the A/C, but there was a leak in the line so by the weekend no cooling. Owner came out Saturday morning w/o charge. Monday morning 4 techs showed up, resolved the leak issue and now it's working better than before."

"We highly recommend Cummins Heating & Air. PROMPT phone response & in-person arrivals. All of their team members are PROFESSIONAL, FRIENDLY & KNOWLEDGEABLE. Their use of phone, text & email provided us with CONVENIENT ways to stay informed. Finally, the results they delivered were of the highest QUALITY. When a different company we had used in the past was too busy to take on our project, we searched Google ratings & then reached-out to Cummins. They have definitely earned each & every one of their 5-star reviews. We had them install 2 mini splits at our commercial facility. In these 100+ degree temps, we could not be more thankful for the smooth transaction, from beginning to end. Cummins is a business we are pleased to associate our reputation with. Contact them for your heating & air conditioning needs… We believe you will be glad you did!"

"I’ve used several different heating and air companies in the past. Cummins Heating and Air is by far the best I’ve ever used! These guys are prompt and professional! They are very easy to work with and always willing to help! The craftsmanship and quality of work is top-notch. They were highly recommended by some of my friends, and they did not disappoint when I chose to have them redo my entire heating and air system! They stand behind their work, which is hard to find these days. There’s nobody else I would rather use than Cummins Heating and Air!"

"My husband had contacted Cummins Heat and Air about a condensation issue we were having in the attic. He is a person that can pretty much fix anything himself. They told him what he would need to fix it. He got the parts but passed away suddenly before he could fix it. They came and took care of it for me at no charge. It is not often you find a business that will tell you what you need to fix the problem but then fix it for you when you couldn’t after all. Good, caring people. Thank you 🤗"

"The gentleman who came on 12/21 around noon figured out what was wrong and ordered the control board. We didn't own the house when the original unit was installed in 2015. They honored the 10-year warranty for the part! Saved us $520!! He came back out the next day and installed it before noon when it was 0° and -21° windchill! Did cost us two service trips, but they earned it in those low temperatures and quick service."

"The owner, Jason, has been a pleasure to work with. He and his staff are friendly, work efficiently, and are doing a great installation at my home. Jason identified potential shortcomings of a previous installer, and corrected those issues. Now I have three functional HVAC units installed that will fit my needs. I look forward to a long lasting relationship with this company to serve my HVAC needs in the future. Still very pleased with Cummins Heat and Air. Great people to work on your HVAC systems."

"I am building my own house and got three bids for a new HVAC install. Cummins was right in line with one of the others, and a lot less than one of the big Trane dealers in Bartlesville. So far Cummins heat and air has been my best and and most reliable contractor!! They are very responsive to request and do great work! I couldn’t be happier with there end result!!"

"If you are having to call an HVAC company, odds are your day has been pretty sour. Phil was beyond exceptional. He was quick, he was courteous and when the part we needed wouldn't be available for a few days, he got us set up with a couple portable units to hold us over and make sure our 4 month old was comfortable. Can't thank him enough for his hard work."
