"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

"Contacted us right away. Arrived on time, very professional and improved our attic with new fan and rewired the lighting. Considering hiring them for our air conditioner installation."

"I called Kyle to help with some smart thermostats. He got back to me fast and setup an appointment for the same day. In the middle of that install, the pumps in my basement failed and it was filling with water. A quick trip to get supplies and he had me fixed up in no time. He was able to get the basement pumped out and new pumps installed, too. All in all, a fast, smart, courteous, and super knowledgeable guy that just became my "go to" for all thing HVAC... and beyond"

"I hired Desmond for an AC and heating install. Desmond spent time explaining the different options and was really diligent about selecting the right option for us. Never pushy. He stayed late to ensure the system was working and called to check a few days later. Very professional and good value for money. I ll definitely use him again."

"It was fine. It took while to get it scheduled because I wasn't ready to have it done. It involved taking my back door off and I didn't want to do that in January and February. The stuff that I needed to have done didn't take 4 hours. What I was having done wasn't difficult. He showed up on time and he seemed to know what he was doing so I can't ask for more than that. There was no worst part. The best part was he was a nice guy. We had something in common to talk about so we were able to chitchat while he was working. I think it was worth a hundred bucks. It took a while to get it scheduled. I would possibly use them in the future if I needed more the same type of stuff done."

"I can't say enough great things about J & M Cooling and Heating! The installation of my new central air system was an outstanding experience. A special thank-you to Dan, the supervisor, who made sure everything went smoothly from start to finish. He was professional, knowledgeable, patient, and took the time to answer all of my questions. It was clear that he genuinely cared about making sure the installation was done right and that I was completely satisfied. I also want to recognize the incredible installation team. They spent days working in an extremely hot attic installing my new system, and despite the challenging conditions, they never once complained. They worked tirelessly, stayed professional, and remained courteous and respectful the entire time. Their work ethic, positive attitude, and attention to detail were truly impressive. They treated my home with great care and left everything clean when the job was finished. My new central air system is running perfectly, and I"
