“Simply put, they are experts. The tech that came to my home was friendly, thorough, and very professional. He took ten minutes to explain the exact problem that my unit was experiencing in terms I could easily understand.”
“Jim and his team were awesome from the start of the project, to laying out the best paths for the ducts, to providing efficient heating and cooling, and ending with the final installs and cleanup. I cannot be happier with our new system for our 60-year-old home.”
“Select initially came out in response to a broken system. We got a new, efficient system, and it has worked very well ever since. It came with a ten-year transferable warranty from Select, and we have had them out twice a year ever since. Things have been good. Select has been dependable.”
“Select did an excellent job. Jim Workman and the staff are outstanding. On-time, professional, and very clean.”
“Select, especially the owner, Jim Workman, has always given me excellent service in the past.”
“Select did a great job with my system. We had a PM done and our tech was fantastic.”
“Did a good job.”
“The technician arrived as scheduled; he was extremely knowledgeable and efficient. This was one of my best experiences with any sort of home services company.”
“My renter said the tech was very professional, nice, and got the job done.”
“I had my gas heating and A/C system replaced. The new equipment recommendation was appropriate. The system has been installed for two years and performed very flawlessly. All problems encountered during installation were resolved quickly resulting in a high quality installation.”
“Good service, knowledgeable, and polite workers.”
“Select Heating and Cooling did an excellent job of installing two zone heating and cooling in our home. We also subscribe to their twice-a-year checkup and they are very prompt and thorough when we schedule that work to be done. We have been completely satisfied with their work.”
“ Good service, knowledgeable, and polite workers.”
“The service representative arrived on time. He was courteous and professional. As soon as he heard the noise my dryer was making, he had a pretty good idea that he knew what the problem was. He quoted a price for the repair and presented me with options had the problem turned out to be more than what he suspected. He took the time to listen to and answer all of my questions. I could tell he was very knowledgeable and experienced. The problem, as he suspected, was worn/damaged drum wheels. The repair took about 30mins. In all, I was pleased with service. I would definitely do business with this company again.”
“Select Heating & Cooling came to my rental house, and they were able to address and fix the issue. The coolant in the air conditioning unit needed to be refilled. I'd give them an A.”
“I thought they were pretty good. They did a really nice job when they came in and did the work, and they've been very good as far as keeping checkups going and all of that. They installed a new furnace and a new air conditioning system. I chose Select Heating & Cooling over another company because I went out and got three bids, and I just liked what they were offering. The owner came out and walked me through everything. It was a good experience. I would give them an A rating.”
“They serviced our furnace and air conditioning units. The technician was thorough, he showed up on time, and they called ahead to say he was on his way so that we had a heads-up that he was indeed going to show up. We chose them because we had to have the furnace serviced, and the local person was unable to come out. They referred us to Select Heating & Cooling, and they came out and serviced it. They ultimately replaced the unit and have been servicing it ever since. I would give them an A rating.”
“We're very happy right now—no problems. We'll be calling them for help if we do have problems. We're satisfied.”
“I have an annual membership with them. They're quick, efficient, and timely. They just moved my air conditioning unit. I would give them an A.”
“Select Heating & Cooling was fantastic—we loved them. The owner was incredibly knowledgeable and sincere. I asked him some hard questions, and I thought he was very thoughtful in his responses. I felt like he was really trying to get me the best. They replaced two of our heating and cooling systems. They're an A.”
“They were responsive and honest. Another company told me I had to replace my heating and air conditioning. My friends had used Select, so I decided to call them for a second opinion. They told me that I needed a couple repairs, and then I would be good to go. I'd give them an A rating. They did an amazing job.”
“Working with Select Heating & Cooling was a good experience. I liked that they were responsive, and they did the job correctly.”

“I'd used the company before. They've done more heating and cooling work, but also several plumbing jobs. They're high quality. They just seemed to be professional about the job, and they got the job done. The technicians were knowledgeable and professional. I heard of them through neighbors, and I would recommend them. All around, I'd rate them as an A-.”
“We had a leak in the air conditioning line, and they came right away and were able to fix it. They handled it very well. The response to the call and their quality of work made our experience with them a positive one. I felt like they were very respectful of their surroundings, and they were able to do the job in a timely manner. I would definitely consider using them again. I found out about their services through a friend, and I think they're an A+ company.”
“Select Heating & Cooling replaced my HVAC unit. The customer service and the quality of work were good—my tenant hasn't complained yet. I would use them again, and I'd recommend them. They get an A+ from me.”
“Select Heating & Cooling put a new air conditioning unit in, and I thought the technicians did a great, nice job. So far, so good—they deserve an A+ grade, and I would recommend them.”
“They did a tune-up on the furnace, and he did a good inspection. The guy was on time and very efficient. I would give them an A+. They did a good job.”
“They put in a humidifier and a dehumidifier. We had a new product that they hadn't seen before, but they took their time and figured it out. The quality of the work was great. We were happy, and we've had no problems. They were on time, and they were really respectful of our stuff and our house. I'd give their service an A, and I would recommend them.”
“They put in a new HVAC system, or at least replaced the air conditioning compressor and coil, and it's worked pretty well. There are actually two systems, one on each floor. We've had a lot of hot days, so we've definitely had a chance to test them. I thought the technicians did a very good job. They started at 7:30 in the morning and were there until 6:30 at night. At one point, he had two or three guys helping him because one guy had to bring another unit, and they had to physically move it. The cleanup was very good, and he called me a day later to follow up and make sure everything was OK. A friend of mine used them last summer to put an air conditioning system in her home, and she recommended them. I would use them again, and I'd definitely give them an A.”
“Select Heating & Cooling installed this small unit of tubing. I went with them because they responded right away, and the workers did a good job. They came on time and did it correctly. It's held up fine, so I'm very happy. I would use them again. They did A-level work.”
“It was freezing because I was having trouble with the outdoor heat. I told them I really needed them to come, and they came. They had to come out a few times because the thing kept screwing up, but they decided to put a new coil in. Overall, I'm happy. I have no complaints; everything was good, and I'd use them again. The technicians were good, the customer service was good, and it was finished within the time frame they'd told me. I'd rate the company as an A.”
“They did an emergency air conditioning repair. They were able to get there when nobody else was able to, and they fixed it quickly the first time and did not leave a mess. They were on time and proficient. I was happy. They're a very good company, and they did a very good job. They went with me to the customer's house, and we got positive feedback from the customer. We were referred to them, and we've used them for the past two years. I would give them an A.”
“Select Heating & Cooling replaced an A/C unit. I heard of them through word of mouth. I was fine with the work; it was good. I'd rate their customer service as fine. All around, they're an A.”
“Select did cooling, and everything was fine. I had a good experience with the company; they were on time and on budget.”
“They just came to do a checkup on the heating and cooling system—it's in the contract. Everything was good; I don't have any complaints. Select Heating & Cooling gets an A.”
“I'd just moved into my house, and my A/C wasn't blowing cold air. They just needed to add more Freon, so it wasn't a big deal. Overall, the tech seemed really professional. He was clean and well spoken, and he seemed like he knew what he was doing. They deserve an A grade.”
“I'd say the experience with Select Heating & Cooling Corporation was good. I would give them an A rating.”
“He checked all the components of the HVAC system so it would be good for the winter, and he gave me a report. The guy was fairly clear in his explanations, and I liked the thorough job he did. He was pretty efficient and got it done quickly, which was all I was looking for. We had just moved into the house, and the previous owners had apparently used them. It was fairly easy to schedule an appointment, and they showed up on time. They let me know when the driver was going to be in the area so that I could come home from work to meet them. It was a fairly painless process. I'd rate them as an A company, and I'd recommend them.”
“Select Heating & Cooling was on time and within price, and it all seemed to work OK. They were on schedule. The quality was fine, and there wasn't any problem with customer service. There was one issue, but they fixed it. I would recommend them. They get an A grade from me.”
“We had an old house, and Select Heating & Cooling did some work on getting the system up to par. They cleaned, they upgraded, and they replaced old pipes. The quality of work was very high—it has held up very well. The technicians did excellent work and were very responsive and courteous. It was very good; we didn't have any problems. I would use them again—A+.”
“The gentleman from Select Heating & Cooling was amazing. He was just very sincere. He genuinely took his time and answered my questions. The guy was there to do a good job, and he wanted to make sure we were happy. They definitely are an A+.”
“Select replaced an entire air conditioning system for me. It was an indoor and outdoor unit. I've had service contracts with them for two homes for almost a year, and everything's been great. I always recommend them—they do A+ work.”
“They did a wonderful job. They removed the old unit and put in a new one, so they replaced the whole A/C system. It was excellent. They're quick. As soon as I called them, I set up the appointment with them, and they were on time. The tenants in the house are very happy with the system and the way it's working—it's cool and nice, so no complaints. I would give them an A+.”
“Select Heating & Cooling did a great job. They repaired a water heater and a main line. They worked hard to identify the problem and stayed after to fix it until it was done. The workers were great, and the cleanup was perfect. They would definitely be an A+.”
“Select Heating & Cooling is a very awesome contractor. They were very good. I liked everything that they did, their management, and that they were knowledgeable technically. I had an outside sensor pressure unit put in, and a condenser coil replaced in the attic for the air conditioning. Everything was good—A+.”
“The very last thing Select did was supply and install a new kitchen sink and faucet, and then transfer the disposal to it. I felt like their level of service and follow-up was really top-notch and professional. They responded in a timely fashion and cleaned up well after their service, too. They definitely seemed to be tuned into that level of service. I would give them an A+.”
“Select replaced the coils and the outside units for the A/C, and I was very happy with their service. It was excellent. I would rate them as A+.”
