I was charged over $600 for the tech to simply replace a kitchen faucet, which I had already bought and had all the parts for, so that price was just for labor. The tech was here for less than an hour and it was a simple installation, so $600 seems very high to me. The invoice had no details of what went into that charge, it just says "install customer provided faucet and remove existing faucet."To add insult to injury, the tech also said I had a leak under my sink and that me garbage disposal needed to be replaced- which wo... read more

The **************** and ******************** are horrible. The one person i did talk with was great, but everyone else was horrible and the business practices are questionable. I called to have a gas leak investigated and had a tech come out. They told me they did find a leak and would need to replace a gas valve. I then spoke with dispatch and said seems like both the part and labor would be covered, however the tech would need to verify before doing work. No discussion with the tech or anyone in the company provided a quo... read more

Needed a new kitchen faucet because the old one was poorly designed and constantly leaked/ dropped. Had to tighten the cold handle constantly. Broke down and paid $1300 for a new kitchen faucet. I picked a different designed faucet this time, the price of the part was $800, much more than the old faucet, but so far well worth the price. Bought a single handle faucet instead of the old fashioned 2 hot and cold handles. Works wonderfully, and has a lifetime warranty for it. Company will send a new part in the mail for free if ... read more

The three year old furnace they recommended and installed had a circuit board that fried over Thanksgiving break while I was away. It took until Monday to get a service technician there and he ordered the wrong part! They came to install it and said they would reschedule on Saturday. I called on Saturday and found out they were closed until Monday. Two cold weeks and my furnace still isn’t repaired! Plus I paid in advance! UPDATE: They replaced the control board three times and it continued to fail. I also have had 1/4" of w... read more

I have used them before and it took 2 techs to fix AC problem. The young guy didn't know anything so the older fixed the problem. Problem now is I called about cleaning the furnace not a through clean but dust and cobwebs out. They had a promotion for season clean and tune up a cost of $129. The guy came asked me what I wanted told him his comment was that would be between $800 and $1200. Told him what the office said and he said they do not know the pricing. So I said want the $129 service I was quoted. He began to badger m... read more

I feel that I was taken advantage of by having GAC come out to try and solve a noise problem with one of my AC units! I was told that I'd have to replace over $2000 worth of equipment. Got 2nd opinion and realized that NOTHING needed to be replaced! What a bunch of THIEVES!

Our experience with GAC Services has been a complete nightmare. We signed a contract for them to replace our air conditioning system, and after nearly two weeks, they have not been able to successfully complete the installation. Their field engineers are unknowledgeable in the key areas needed to complete the effort - particularly on the wiring side. They have sent numerous technicians over, and the end result is that the thermostat will not turn the system off, and so the A/C system is operating around the clock running the... read more
