Glenn's HVAC & Electric is unbelievably responsive! They do what they say they will do & give free estimates! They replaced out thermostat last week! That's how we found them.

If you need HVAC or electric work done, don't even bother to call anyone else! Glenn's got you!

Shout out to SARAH for her reassuring words and expediting the service call. WHAT A DIFFERENCE! I cant recommend this company high enough!

I was able to do school work and not even be distracted. These two that came out were very professional. Even told me when they were leaving for their lunch break. They informed me that they had to wait for an additional part, and made sure that I was happy with the installation. ComfortMaster has always given me great service and I will always call on them for future work. I recommend them to everyone that I hear needs AC work. Everyone within the company is friendly and professional. From the administrative staff to the on site work staff. If you are in the Greenville area, call on them.

A Harsh Lesson in Trust: Thousands Paid, Zero Relief from Delcor's Broken Promises. As someone who…read moreco-financed the HVAC installation with Delcor, I felt compelled to share my own perspective, because this ordeal hasn't just cost us money; it's cost us trust, time, and peace of mind. From the outset, we were sold a vision of reliability. A reputable company, a full-service experience, and the comfort of knowing our tenant would be taken care of. What we received instead was a dysfunctional unit from day one. Two weeks later, it's still not working--and not a single person at Delcor is stepping up to resolve the issue in any meaningful way. I'm not just speaking as a frustrated customer--I'm speaking as someone who tried to do everything right. We didn't go with a cut-rate contractor. We chose a well-known company and paid upfront for a full system. That trust was met with radio silence, departmental runarounds, and a shocking lack of urgency. Let me be clear: the unit had defects from the moment it was declared "installed." It leaked. It was missing critical components. And instead of taking accountability, Delcor has chosen delay over resolution. They continue to request final payment for a job that isn't done. Not working. Not livable. In the meantime, we had no choice but to spend more out of pocket for a temporary cooling solution--just so a human being wouldn't have to suffer in an unconditioned space during a heatwave. If you're thinking of hiring Delcor, ask yourself this: What happens if the install goes wrong? Who will pick up the phone? Who will stand by their work? Based on our experience, the answer is no one. This review isn't about venting--it's about warning. If you're looking for true end-to-end service, or a company that takes responsibility when things go south, I urge you to look elsewhere. The cost of choosing wrong goes far beyond dollars.

My issue with this company has been the severe need for more communication between the front office…read moreand the technicians. Their workers showed up unannounced to begin the installation of a new HVAC unit in the property next door to me a day and a half later than I was told, without notice of when they would arrive. When they did arrive at the property, they just walked in and began working without notifying anyone that they were over there. After they had finished, they up and left without saying a word. I received a phone call the next morning asking if they were finished, and after paying I was told that an inspector would come to the property to ensure everything was installed correctly. They never showed. To be fair, I called the inspection company directly and ran into the same issue and eventually gave up trying to get them to come out, so I won't put this entirely on the fault of Service Plus. Lastly, after all of the work had been completed, I had to make several phone calls to the office to correct basic information on my final invoice. This company seems to do quality work, as I haven't had any issues with my new unit. However, they need to do a better job of communicating with their customers and handling things a bit more professionally.

Unfortunately we had a problem with a toilet during Memorial Day weekend. We called the company on…read moreMemorial Day and were told that he had two service calls to go on and then he would be by to give an estimate on the work. (We also needed two faucets to be replaced and figured it would be easier to get it done at the same time as the toilet.) Well, he did not show up at all that night. We didn't receive a courtesy call either. It only takes a moment to call someone back and apologize that you won't be able to make it that night after all. Hopefully they pick up on this practice in the future. The next morning, the guy called us back and said he would be at the house around 9 or 9:30 and apologized that he got an emergency call the night before. (Again, it only takes a moment for a courtesy call once you've told someone you're going to be there for an estimate.) He did arrive around 9:45. He did a quick look at the work and quoted at half what another company quoted over the phone (without seeing any of the work.) He stayed and did the work. It took him a total of six hours to complete the valve replacement on the toilet and installing the two faucets. He had two cell phones with him that rang constantly. And every time one rang, he took the time to answer it. I thought this was quite a bit unprofessional, especially since some of the calls sounded like personal calls. The calls greatly slowed down the work. Unfortunately, one of the replacement faucets we purchased was faulty and we had to get it replaced before he could finish the work. During the twenty minutes it took to go down to Lowe's and replace the part, he left to go do another call. Luckily it didn't take him long to come back after we called him and told him we replaced the part. So after this six hour ordeal, he finally finished the work and stuck to his quoted price. (Lucky us!) I can't really say I recommend or don't recommend this company. If you have all day for your plumbing problem to get fixed, then go for it. The guy is very nice. (This was just a little pet peeve, but he talks extremely loudly and I had a sleeping 4 mo old in the house.) He also kept asking us to clean up after him and tighten things here and there. Some things I feel he should have been doing himself. I probably won't use this company again.

I do not recommend Mr. Thomas due to he OVERCHARGES. I had him do some work for me at a couple of…read moreother locations and he was very fair and helpful. However today I had him install a water heater that took him 45 mins. The only thing he had to do was take it out of the box and connect it. All the wires and fittings were already there so literally hook it up was all he had to do and he charged me 250.00. Told me this is what they been charging for 20 years. Could have been that way but I am sure there was a lot more to that price than connecting a couple of hoses and wires. On the high side I did not expect to pay no more that $100-$150.00 for this job. Reading the other review it appears to me he makes it up as he goes. The invoice he just jots down something to make it appear that he did something of value for the price.
