"They found that what appeared to be a leaking water heater was actually a clogged drain line from an adjacent HVAC AprilAire humidifier. He also determined the pressure control valve had failed and the reading was 130 psi. He had the valve on his truck so I had it replaced even though the price was several hundred dollars above two other quotes."

"I sent an inquiry through their website and they responded within minutes to setup the appointment. So far so good. Their website indicated that they serviced Magic Chef appliances and I put in the comments that I needed a Magic Chef wine fridge repaired.
The tech (Ivan) was due to arrive between 2pm-4pm on 8/12. He actually called before 2pm and said he was outside - again, so far so good.
He came in and looked at the wine fridge and determined that the fans needed to be replaced. After calling his office, unfortunately they don't carry parts for a Magic Chef wine fridge. This didn't make sense to me, since I had specified what I needed repaired when I made my appointment.
It gets better.
While he had the fridge pulled out from under the counter, he pointed out to me that the electrical outlet was loose and recommended that I have an electrician come and have a look at it. He also advised me that I could probably call another company to repair the fridge, but by the time I paid for parts and labor it would probably make more sense just to buy a new wine fridge since they're not that expensive.
This is the best part - he then presents me with a bill for $8, which is what they charge for a service call. Great, I thought. That's really reasonable. I pulled out my Visa since their website said they accept all major credit cards. He asked me if I could write a check instead. Weird, but no big deal. Then, he says to me that if I appreciated the fact that he pointed out the electrical issue, I could GIVE HIM A FEW EXTRA DOLLARS. He had a heavy accent, so I wasn't even sure I heard him correctly. He repeated himself and again ASKED ME FOR EXTRA MONEY for the advice he gave.
So not only did he NOT fix the fridge, he refused my credit card, and then had the balls to ask me for an extra tip!?!?!
I wrote him a check for $20 and resolved then and there to write this review. I would absolutely not use this company again - they are obviously completely sketchy.

"Called several places for quotes and decided on G Force plumbing. Rob J came by on Jan 4th 2016 to initially install a 50 gallon electric water heater. I then decided during the install that I should go ahead and replace the gas water heater located in the basement as well since both were the same age. Rob made a call to have a gas water heater delivered to my home and installed two water heaters the same day. Rob was great and very professional. Fast forward to December 12th when I had my furnace tuneup performed by a Heat/Air company. The guy noticed that an expansion tank was installed in the upstairs water heater but not the downstairs. He suggested I contact the company that installed the water heater. I contacted G Force to ask if that was normal. Jamie had indicated that Rob may have thought that the one expansion tank was all that was needed due to how he thought the water lines were configured. Jamie did say that an expansion tank should be installed in by the basement water heater after describing to him the number of bathrooms we had at the house and where each water heater was located. Two nice guys from G Force came by five days later to install the expansion tank and finished the job within 20 min. Installed two water heaters and pressure reducing valve. Everyone I dealt with at G Force have been nice and professional. I will definitely use them for my rental properties."
