A selection of 417 homeowner reviews:
“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.”
“Select was very fast and quick; they fixed the heating problem right away. I would definitely grade them as an A.”
“The air conditioning was not working, and Select Heating & Cooling Corporation came and fixed it. I would give them an excellent grade.”
“It was all right. The quality of their work was OK. Everything has held up well. I would recommend the company. They're good, and they did excellent work.”
“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+.”
“I thought the work that Select did for me was great. They came in, and I think they replaced a coil and some other electronics in our air conditioner. They got it up and running again, and they also serviced our heat. The quality of the work was tremendous—it was great. I think they'd be an A.”
“Select Heating & Cooling did my winter checkup. They came to look at my machine because it was making a lot of noise. They serviced it, and it was fine. The quality of the work is good. I started a contract with them. They're an A—excellent.”
“Select Heating & Cooling did some heating and air services for me over the last year. We had a problem last year, and Jim came out and solved it. This past August, I made a decision to put in the new heating and air conditioning. They came out, and it went in. Everything's fine. I'd recommend them, and I would give them an excellent grade.”
“Select fixed our air conditioning, and they did a great job. We were having some temperature problems in our upper level, and it's held up great. They mostly put in Freon and worked on our thermostat, but we would definitely use them again. They were awesome. They didn't have a part one day, and they sent someone out first thing the next morning. It was even a Saturday or something, so they were really good. I would give them an A rating. They were great.”
“Select was fast. They responded well in setting up the appointment, and they cleaned up well after their services. They're the type of company I would use in the future. They came and did a checkup of the unit, and put in a new vent. They did general maintenance for me, and I didn't have any issues with them. I'd give them an A.”
“They replaced an entire heat pump system for a client of mine in a condo. They finished in a timely fashion, and they didn't leave anything substantial behind. The quality has been good—no problems. The installation had a lot of challenges, but it wasn't their fault, and they handled it well. I would use them again. I would give them an A.”
“Select Heating & Cooling solved a last-minute problem with our air conditioning going out, and they bent over backwards to get it done in a very quick manner. They deserve an A+.”
“Select Heating & Cooling did some heating and air services for me over the last year. It was a great experience. They came out on a Friday, diagnosed my air conditioner, and got it back up and running. They thought it would last two weeks, but by Saturday it had died again. Then, they came on Saturday afternoon in the August heat and replaced it. I would say they were an A+.”
“I'm in the middle of a remodel project, so the work is not quite done yet—not for any reason of theirs. It just takes time with a big project. The quality of Select's work is great. Their technician is very knowledgeable, and I would use them again. They finished the job in a timely manner—A+.”
“The technician from Select was very personable and didn't try to talk over my head—I really appreciated that. He was thorough and quick. In our condo association, you have to have a furnace inspection every other year, so I like to go back to Select. They're good guys. I like them—A+.”
“They installed the air conditioning and heating. They gave me an estimate, and they stuck to the estimate. They were very responsive—everything was on time, and when we had a question, they corresponded great. It was a very good experience. They're definitely an A+.”
“Select Heating & Cooling fixed our A/C. The technician was timely. The owner himself came out, and he did a great job. It was A+ work.”
“The work Select Heating & Cooling did for me was very good. They serviced and did everything for our air conditioner, and then they have a contract to do work for the heating and the air conditioner. I think they've done it for both, so they're very good. They're thorough, and they don't try to upsell you. They came and looked at everything, and they explained their contract to us. In fact, I have to send it back for next year. They were very, very good. I'd say they were A+.”
“Select replaced my air conditioning unit, and they were very professional and very quick. The only problem I had was that the unit they had to order was something that was on back order from the vendor that they're buying from, but other than that, everything was great. They were very professional. I left them alone in my house to do the job, and everything was fine. I would give them an A+.”
“I'm a contractor, and I actually use them often for HVAC services for my clients. They were on time and on schedule. They're an A+.”
“Select Heating & Cooling replaced our HVAC system, and I was very happy with their service. The technician was very helpful. They ran into a sea of problems with installation because we have an older house, and he provided a workaround for his charge because it was something that he couldn't have anticipated when he first gave us the estimate. So, in my mind, they went well above and beyond what they were hired to do. We did have them out for a follow-up because something went out on the A/C. There was a defective part that they replaced very quickly, and they came to see it on a weekend. So, I would say they were prompt and went above and beyond, and in an unanticipated circumstance, they were professional and courteous. I would give them an A+.”
“Select put a new air conditioning unit in. They stayed on budget, and the work was on time. The installation and the cleanup were both done without any issues, and the time frame and the cleanup were good. I would give them an A+.”
“I had a kitchen renovation, so they worked on the ductwork. I liked the friendliness of the workers and the quality of the work. They respected my property, and they didn't take advantage of my time. Overall, it was a good experience. The time frame the work was finished in was fine—no complaints. Everything was fine. I'd say they're an A+.”
“Select came out a couple of times. First of all, they changed my thermostat, and then one time, they did some stuff in the unit. I don't honestly know what it was, but there was something in there that needed to be refilled or something like that. After that, it was really good. One time, it made noise, and they changed another part, so they did a great job. I actually recommended them to my brother and my family because they did a great job. They've been on time, and they did a good service for me. I was happy with them. I would give them an A+.”
“They worked on my air conditioner, and they were very, very nice. They were very polite and very thorough—a very nice company. I'd give them an A+.”
“Select Heating & Cooling installed a new air conditioning unit for me. They were timely, comprehensive, and friendly. I'd give them an A+.”
“Select Heating & Cooling came out twice because I had two issues. I think it was a flame igniter first, and they fixed that. Then, the A/C unit wasn't turning on, but it was a stupid thing we did that caused that to happen. They came recommended by a lady in my neighborhood who, I believe, knows the owner of the company. I feel like I received good quality work. I was briefly on the phone with them, and I thought the customer service was sufficient. I would like to give them an A+.”
“They came in and did an inspection. This was an annual inspection for the A/C, and it was my first time using them. I was satisfied with their work to the degree that I would most definitely call them again if the need arose. The technicians arrived on time and cleaned up as I desired. Everything was explained as I would hope. I would give them an A+. I was very, very satisfied and have already recommended them to another couple.”
“Select Heating & Cooling did a heat pump and furnace for me. They were courteous to me, and everything worked out OK. I'll absolutely give them an A+.”
“Select Heating & Cooling had to replace the A/C and air handler for me. The quality of work is good so far. They were very efficient—they came out and did what they were supposed to do in a timely manner, and they were very knowledgeable and very professional. I would give them an A+.”
“Select Heating & Cooling put in a heat pump for me. This was the first time I used Select, and I actually chose them because I heard about them through a friend who'd used them and had a good experience. I would give them an A+.”
“I need a kick-start on my A/C at the beginning of the year, so Select does it every year. I would give them an A+.”
“Select Heating & Cooling installed a new heat pump, and the quality of the work was good. The worker was really nice and very clean, and he was responsible and helpful. I liked that he worked hard and was efficient—it was great. They were eager to make an appointment convenient to me, and they showed up on time, did their work quickly, and cleaned up afterward. I would use the company again, and I'd give them an A+.”
“I just signed up with Select's annual contract. The last time they were out was a few months ago, just to check the A/C. I'll give them an A+—no complaints.”
“They fixed our thermostat. They have a quick response time, and they're excellent. I'd give them an A+.”
“Select has done work for me a number of times. They've done plumbing and gas installation in the renovated kitchen for me—it was gas and a new drain line. They've also taken care of problems in the bathroom for me and handled issues with venting. They're prompt, and they do the work that they stated that they were going to do in the time that they said they were going to do it. They're definitely A+.”
“Working with Select was a very positive experience. The technician knew what he was doing. He came for the yearly check-up service to the furnace, and he did testing with some type of meter and recognized that some parts needed to be replaced, so we did that. He had to order one part, and it came in about two days later. He came back and installed it, and checked everything out. He cleaned out a pipe that had never been cleaned out, and he showed me how it was so gummed up. It was a pipe that discharged water from the humidifier. I didn't know the thing had to be cleaned out. He had to cut the pipe and then cement it back together, but he had a machine that blew it out. It was all news to me. The response time was OK. I feel this company could be recommended to others. I'll say they're A+ for sure.”
“We were pleased with the work Select Heating & Cooling did for us. They cleaned the furnace for us, and the quality of the work was fine—we didn't have any problems at all. The technician was very nice—didn't have any problems. He did what he needed to do, and he was finished. I would give them an A.”
“Select Heating & Cooling replaced something on the furnace. The timing of the job and the cleanup were good. I would say they're an A.”
“Select showed up pretty much on time. They were installing a new air conditioning unit, and they were very good. I normally work nights, but they didn't make much noise—they were really quiet and got done fast. I'd give them an A.”
“I thought Select Heating & Cooling was reliable and quick. We had a big storm here three or four months ago, and we lost power. We had a problem with the A/C compressor—some device in the compressor had blown out because of the coming and going of electricity. I have maintenance with them, and they came the next day to repair it. I would give them an A.”
“We manage a house, so we were the ones that made the arrangements for Select Heating & Cooling to do the work at that house. I know the tenant over there was happy with the work, and everything went as planned. It worked—A.”
“If I remember correctly, I think that they were the ones that came in and were doing some work on making sure that we had some kind of check on our system. Maybe a light was going on that wasn't supposed to or whatever, so we called them to come and check it out. Maybe it was the beginning of a season, and we wanted to make sure that everything was working properly, and they were really great. I believe this was the company where the folks that were on the phone were really nice. The folks that came out were great, too, and the people that were scheduling and that kind of thing were very accommodating. I thought they were professional. They were on time, and I thought they did exactly what they said they were going to do. They were clean too—everything that you would want in a vendor. They were a pleasure to do business with. I would grade them an A.”
“They did some repairs on a compressor. It wasn't working, so the belt was replaced and there was a wire loose. It's fine now. They were very good—A.”
“Select installed a system for us. It was really good—they were really informative. They were prompt with their services, and they finished their job in a timely manner. We just had a heating check from them the other night. I liked that they took the time to answer our questions and were knowledgeable and very helpful. We didn't feel as if we were pressured into anything. They were really good. They were nice and presentable, and I would give them an A.”

I was very pleased with absolutely every aspect. They replaced my entire system and were able to do something that other companies couldn't, which was to provide a quality product. The new system is more efficient, and the house is definitely more comfortable—it's just a win all the way around. They're A++.

Select Heating & Cooling was excellent. I wouldn't hesitate to call them if needed. The problem with the HVAC system was complicated, but their head person was extremely knowledgeable. He was terrific—perfect. Their customer service was excellent.

We were really happy with Select Heating & Cooling. A few years ago, they replaced our original air conditioner, and recently, we put an addition on the house, so they installed a whole second-floor system. They were perfectly willing to do anything we needed, and I could really trust them. I'd give them an A+.

I had a very positive experience with Select Heating & Cooling. We had a difficult place to do the installation, but they had a very creative solution to the problem. I thought they were excellent. They’ve been right there for us any time we’ve had any problems at all. I’d give them an A+.

Select Heating & Cooling did a great job. They’ve done several things for me. They’ve replaced water heaters, they’ve worked on my air conditioning unit, and they’ve worked on my duct system. The quality of their work has been great, perfect. It was all A-grade work.

The owner of Select Heating & Cooling, Jim Workman, has been maintaining our heating and air conditioning for years. When I hire them, they finish the work in a reasonable amount of time, they clean up after themselves, and everything goes as planned. They’re A+.

Select Heating & Cooling did the air conditioning, the furnace, everything. The person was fantastic. Actually, there were two of them that came out and installed everything; they were great. I'd give them an A.

We were satisfied. They fixed a fan in the outdoor unit. It was quick and thorough, and I liked it. They finished the job in a timely manner. They were prompt with their services. I liked the fact that they showed up on time, they did what they did in an efficient manner, and they left. I'd give them an A.

Select Heating & Cooling put in a gas fireplace. The quality of work was excellent. They were prompt with their services. What stood out about the company to me was customer service. The technicians that came out were awesome—A.

They worked not only for me but for two of my clients as well. For me, they installed a new furnace, a new A/C unit, and they maintained it. For my clients, they come out and do their twice-a-year service and do any repairs that are needed. It would be A's across the board.
