"I thought it went well but took longer than I expected. Mechanic Leo bought the new tank and pipes in when he arrived. I believed Leo arrived around 7:30 pm. He completed the installation around 11:30.pm Leo went out to his truck, stayed outside for a long time, in fact, my son Vann went out to ask him what was taking so long. When he came back in, Leo told me there would be an extra $100.00 We explained that we had been quoted a price of $1,300.00.. so he said to call the i office and they would straighten everything out, That’s why I called the next day. Everything seemed okay. When I notice the water was much slower, I called to let J&S know. The person asked me a few questions and advised me to check the faucets. Well, that didn’t work and the water was not as hot as before the installation. I called again to explain to J & S what was happening. The person there told me that they didn’t have to come out, and I still owed them $100.. so that's why I called Angi So I decided to check all of the faucets and I realized that the water flow was not coming out properly from any of the faucets So this is what happened. I am just appalled that they haven’t come out or called as of this date. I need them to come out and check this out, something went wrong. We could do a FaceTime inspection that would show the flow of the water."

"Four Seasons arrived earlier than window time and came out to perform the yearly maintenance on my furnace. He said Four Seasons was offering a discount for cleaning the water heater. Since I've only lived here five years and had no idea when it was last cleaned, I also had him clean out water heater. He did an excellent job on both, replaced my furnace filter, and left the area cleaned. He explained everything he did, answered all my questions and said my water heater was very dirty and should now run more efficient."

"Gary fixed a water heater for me in a prompt and efficient manner. He offered me a number of repair options, which I appreciate. He had the parts needed on the truck, which made the job much smoother. I am always shocked at the cost of repairs, and I suppose Gary's price was right in line with others."

"I would highly recommend TDH mechanical to anybody. Their price was exceptional and their work was spectacular. I got bids from almost 10 contractors for a new boiler and hot water heater system for my house. TDH was the cheapest in the lot but that was not necessarily a good thing in my mind. The last boiler had been in place for a decade longer than I have been alive and I wanted to do the right thing with a trustworthy company with a system that would last. TDH discussed different options with me for weeks as I was indecisive and was extremely helpful at evaluating different systems. I finally chose a system and went for it. At this point I was pretty terrified. I had talked to references that he had given me and researched the company but I was about to spend well almost 15 grand and they were the cheapest of 10 companies by far and well... I was scared. The guys arrived exactly as scheduled and completed the work with a level of detail that exceeded my wildest imagination. In just a few days they removed 100 years of dysfunction from my house and did an absolutely spectacular job. There were a few minor issues as you would expect with a project like this and they returned promptly to take care of them. The sub contractors that they used for electrical and plumbing were top quality and every part of their service exceeded my expectations. The village inspectors were even more impressed with the installation than I was which is an excellent sign. Neither the plumbing nor HVAC inspector had a single negative comment about the installation. I highly recommend TDH and will definitely use them again for my future HVAC needs."

"We actually had called Emanuel Brothers first since their name was on the water heater. But, after the amount of time and money they quoted us I decided to check Angie's. We had John come out and take a look and he told us he could do the same work for almost $800.00 less! I can't say I didn't have some trepidation. First, just how is it possible to do so much less work than we were told would be necessary (we had 2 water heaters. Neither of which worked after nearly 20 years, that had to be removed first to make room). And, for so much less. Emanuel Brothers were so perplexed by our situation that they had to call the boss to come out and explain everything to us. But, John had this "no problem" kinda attitude. Both refreshing and disconcerting. But, in just a couple of hours he had not only delivered a new water heater, he had the other 2 removed and the new one installed. And its been working flawlessly.
