Well, let's see. Weird things happening with my A/C, moisture detector seems to be shutting it down. They couldn't figure out the issue, so I said I was fine just replacing the moisture detector (which was part of GEM's installation of the whole A/C just three years ago). First quote: $1,000. I said no thanks. After going around in circles, the quote was down to $550. "Significant discount. Best we can do, it's an expensive part. It's like a little computer." I declined again (numerous times actually). So out of curiosity I searched online for that "expensive part." I found the Diversitech flood detector model WS-1 (which is what I currently have) for $65 on Amazon. They wanted to charge me $1,000 for putting that in. Paid $149.00 for that system check. If it turns out that sensor does need to be replaced, I can tell you who I WON'T be calling. GEM. read more

We recently had a whole house AC replacement completed by GEM. This involved two separate systems, as well as the outdoor units. The technicians were well trained and explained all of their procedures. The project took two days and required both electricians and plumbers. All materials were cleaned up before they left the property. Kudos to GEM and specifically to Edgar and Josh. read more

Outrageous cost. Changed close to $400 for half an hours work. Will NEVER use them again and recommend others do same

I use GEM for all my HVAC needs. Today I had another great experience with the pros at GEM. Perfect execution. They came for a yearly free check up call on a Friday. They pointed out a few issues with valves and expansion tank. Came back on Monday, did exactly what they explained they would do. On time, on the mark. The cost was exactly what was quoted. Perfect execution again. Thanks GEM!! The service guys were great. Highly recommend this company. Ken M. & Roe O. read more

We asked for a quote to put in a gas line. They came right away to scope the project but never returned the quote. I reached out but never heard back. It was a huge waste of time for my husband and I. read more

Really disappointed with this company. I had GEM come in for a pretty simple repair and replacement and it went spectacularly bad. In short, what was initially asked for was never actually completed and what was done actually left me with leaking pipes. I called for a replacement of two valves that provide water to my washer machine. In my unfinished basement, the pipes and valves had also become loose from the wall (the foundation), so I asked that they be secured to prevent bending or breaking. I also asked that they take a look at the shut off valve to my water heater, because it had leaked in the past, but had not leaked recently, so it was more of a piece of mind thing. The technician arrived on time and proceeded to look at the valves and piping. After taking some measurements he went to the store to pick up two new valves (this was expected, you cannot have everything on the plumbing truck). The technician replaced the two valves for the washer and replaced the shut off valve for the hot water heater for free, even though he said it wasn't leaking and likely wouldn't be a problem (which I appreciated - seemed like a really nice thing to do). Now for the bad: He never secured the piping to the wall, but instead tried to secure one pipe to a board that held the outlet for the dryer and an outlet for a light. The technician told me that the board fell off the wall, and it wasn't his fault. I accepted this at the time and he told me that he didn't have any masonry screws to connect anything to the foundation (this is interesting, because he just ran to the store to pick up valves). Since he didn't have the proper material, I accepted his side of the story, paid him and thanked him for his work, even though he never completed the whole job (I couldn't just make him stay at my house, if he doesn't have the materials, he can't do the work). I went down to look again at his work and noticed that 1) he didn't clean up anything. Basically, left the basement wet and dirty even though I went down with a towel and said that he could use it to clean up instead of wasting paper towels, which he said he would do. 2) The reason the board "fell off" the wall was because he used a wood screw that was too long, and popped the board off of the foundation (so it was his fault) and 3) the pipe leading to the water heater was now leaking. I ended up having to spend my Saturday purchasing the materials and doing the work correctly. I called to let them know about my disappointment and was told by Angela that the technician disagreed with my story, but when I gave more details she said she would speak with him again and call back by the end of the week. I ended up having to call GEM again, because I never heard back. I finally received a call back from someone who asked if they should send someone out to fix the leak (this was two weeks after the work was originally supposed to be done), I politely declined, since I really wouldn't let a pipe keep leaking for two weeks. They never once offered to correct the situation, offer a refund or anything until my final call when she gave me the empty offer of sending someone out. I would never use GEM again for anything. read more

I had scheduled appointment with this company to replace main water valve/faucet to the house, and was assured the plumber will come during the window when the town shut my water supply. I called again when the time near and got assured about plumber calling before coming over. No one ever called and the town already turned the water back on. I would not recommend this company to anyone since it's so unreliable and not trust worthy. read more
