I called the famed T&G and they tried to rob me blind after they came out with some outrageous pricing for refrigerant.

I message prime time here on yelp and the pricing was up front and reasonable. Tech arrived within the arrival time frame was knowledgeable and completed the task within 20 minutes. I call them first the next time i need service.

The GM said they had to pay for their 85,000 trucks. I spoke with him today and told him that he did say that and on another review, he lied, and did say exactly what i quoted. I do not make things up. He said they spent 15 hours on my job, another lie. (suggesting they were looking for materials which somehow took an additional 10 hours) They spent 4 to 5 and did not even work the entire time. They are THIEVES. STAY AWAY FROM THIS BUSINESS

Jerry is very honest and explained every question I asked employees also very honest and effective. Went above and beyond what I expected and exceeded my expectations! Had the old one out and the new one in in less than a half hour. Very responsible. I would recommend them to friends and family. A furnace is a huge investment. So you need to make sure you go with a company who is not out for commission selling you stuff you don't need. They will be straight up and honest and tell you what you need what you don't and what you might need in the near future. A+ in my book. Thanks Jerry!

I Googled what is generally performed for standard a/c tune up. Here is what I did not see the Tech doing. Did not check refrigerant level. Did not open up furnace to inspect or clean evaporator coils. Did not test refrigerant levels. Did not lubricate moving parts. Did not test capacitors or amp draws. Asked for hot water tank flush. Mine had a weird ball drain valve. The last hot water tank installer put in to let out more sediment out from tank. It was not standard. Power Tech had to procure a fitting in order to allow garden hose type thread to be installed. It did not help that my floor drain was clogged in the basement. Another drain was located and the Tech's self coiling hose had to be stretched out to extreme extent. It put pressure on the fitting. And that made it so the water was squirting out of the fitting and getting all over the basement floor. The Tech only drained the tank once. No flushing/purging/refilling to get all the sediment out. No safety and components check. Tech should have stated a proper flushing could not be perform. Tech was on the phone much of the time. I ultimately left the room so tech could take his calls. 6/24/26 I wanted to update my review after owner commented. When I hired you, your demeanor should have been professional from the start. No customer should have to call you back a second time to ask you do to a proper job. You initially earned my trust when I hired your company. You have lost my trust by performing a really subpar job, but still collected top tier pay for the services. You have cost me to spend double and hire another company who will do the proper job. The job you performed was something I could, and have, done in the past MYSELF. I would not recommend your company.

Edit: We just had them back out to install a new ductless mini-split system to cool our home and their work was, yet again, top notch! They were prompt in coming in and providing an estimate, helped match us with an electrician to get power to the unit, provided us consultation to help ensure we got a unit that would suit our needs today and tomorrow without overpaying, and then did another beautiful install. For both heating and cooling they are prompt, courteous, and I've never seen cleaner work. They are neither the cheapest nor the most expensive estimates we received, but they are the absolute best value for the money you're going to spend.
