Mike Shuper
Michael was awesome and very prompt
Michael the tech for Ray O. Cook Heating & Air was awesome. Not only was he prompt to attend to my heating emergency situation, Michael was very polite and respectful not only to myself & my wife, but to my home. Michael was very professional and educated us on what was causing our problem—on why our heating unit was not functioning. Michael replaced the part that was not functioning. Before you know it, we were back in comfort of a warm home.
We would definitely recommend Ray O. Cook Heating & Air for all of our heating & AC needs.
Dana Wolfe
Very Good Response!
Sales and installation were great and professional, but damaged the bottom of the door frame of the furnace cupboard. We noticed after they left and notified them. They then very promptly responded and sent out a service tech to address the issue. He replaced and painted the damaged frame. Very good response!
Gil Medel
I appreciate his professionalism and follow through.
Paul came to my house to do an estimate for a new HVAC system. Paul is very knowledgeable and explained the varying systems that qualify for the Tech Rebate. He clarified misinformation that other companies shared during their estimate visits. I appreciate his professionalism and follow through. Thank you, Paul.

John was professional and efficient!
My heater was not working, and they had someone out that day to fix it. John was professional and efficient!
Gina Leveroni
That is excellent service, and I appreciate it.
This technician was completely professional and efficient. He paid close attention to all details. When he noted a slight discrepancy in propane flow/rate, he contacted supervisors, and subsequently re-evaluated flow/rate to his satisfaction. Overall, he was able to find the equipment still in good shape, and they will observe it carefully at the next visit to ensure it continues in proper operation in the one area he had questioned. That is excellent service, and I appreciate it. Thanks!

Brandon was right on time and very professional.
Brandon was right on time and very professional. He released a great report for the furnace and replaced the filter, as usual. Did a great job.
Michelle Finton
11/10 stars to both of them.
I had two heaters go out within a couple weeks of each other and had Ray O Cook come out for both. They had good availability and even with needing to order a part they had the first one fixed up within days. It ended up costing about $1400 for the diagnostic and new control board. I wasn't thrilled with such an expensive repair, but it did seem about the going rate for that sort of thing and they seemed legit. I was happy with the level of service. And then our other heater went out. They were able to come out first thing in the morning (on a Saturday, which was great because I can't just take time off work for every little thing) and fix it immediately. Just needed a new fuse which came out to less than $250. Which, I guess might seem a lot for a simple fuse if you know how to fix it, but seemed reasonable considering that included the service call fee. Both techs they sent out (Timothy and Kenny) were knowledgeable, professional, punctual and quick. 11/10 stars to both of them. I really hope I don't need to call another HVAC tech out any time soon, but when I do I will absolutely be calling these guys again.

Today (Jan. 21, 2022), Mike B. performed maintenance inspection on our HVAC system. He performed careful inspection in detail of everything. We are so happy to have Mike here today and happy with Ray O. Cook Heating & Air.
(Feb. 17, 2022) Mike B. came out to install a new thermostat to replace our Nest unit. In our opinion, Ray Cook’s techs are the best in terms of knowledge, professionalism, and friendliness. Before Mike left, he made sure my husband knew how to operate the new unit. We trust Ray Cook’s reputation and each technician that has come to our home.

Today, Mike B. performed the regular inspection of our HVAC system. Mike’s knowledge of the system is exceptional as well as his professionalism and courteous manner. Customers value good service and without a doubt, Mike and Ray O. Cook have provided that fine service.

J Nuno
Very professional and thorough

John Willi
Technician was friendly and thorough.
Technician was friendly and thorough. I did find one of my heater filters in the trash can in the laundry room rather than in the garbage can, but the job was cleaned up nicely except for that. I bought the yearly package so they will call me and I don't have to think about when service is due. All messages and emails were polite and right on time.
Nancie Wiseman
I give them my highest recommendation!
Theron was prompt, professional, and courteous! It was at my mom’s house, and she received an outrageous estimate from another firm and was a bit skittish on getting a “second opinion.” I assured her this was a wise thing to do, and I made sure to be there during Theron’s inspection. He gave his professional assessment in easy-to-understand layman’s terms, simplifying the technical jargon. Most importantly, Theron gave us OPTIONS that are reasonable and appropriate in our circumstances. We have decided to cancel the maintenance contract with the other firm and move over to Ray O. Cook. I give them my highest recommendation!
Pete Bohnhof
