⭐⭐⭐⭐⭐ I can't recommend Harold enough! From the first phone call to the moment they left my house, everything was professional, fast, and fairly priced. Explained everything clearly as well. Top notch all the way.

Beware!!! Harold and Joe are deceitful and negligent! I am currently having a horrible experience. 9 Months ago Harold sold me a "whole new system"(2.5 ton) for $6500 complete. He did not tell me it would not include parts as directed by Carrier for a proper installation. In the winter, the heater did not work and he made excuses to charge me $1,100 (originally billed $1,800, yet quoted by Harold $700 prior to work) for putting another air return hole in my office wall because there was a air restriction and when complete it still did not work. Turns out he installed too small an air opening in the unit and had to permanently remove my UV germ killing light to expand it. He did not connect the condensation line so the unit leaked until I noticed it buckled my 3/4" scraped hard wood floors

They converted our oil boiler to gas and gave a good price. They were professional and kept to the schedule. Over the last couple of years we have had issues with the boiler we chose. Harold has personally dealt with the company, making sure the warranty was adhered to and eventually pushed for a brand new boiler, which we received. They then offered to fit the new boiler for free, even though the fault was with the boiler itself, which they did. They stood by their work, were always out immediately when needed and have given a great service over the last couple of years.

We called T & H this past summer, when our A/C stopped working. The owner, Harold, showed up to check things out; he was personable and articulate. He assessed the options promptly and explained everything to us in detail. His bid was similar to the other bid we had received but the fact that his was a family business and that he clearly takes pride in his work...we decided to give him the job. Turned out to be a good decision. He and his crew showed up on time, in good moods, and installed a brand new condensing unit and furnace (on it's last legs) in about a day and a half. Harold answers emails and phone calls promptly and I just learned he checks his non-emergency messages over the weekends. We put a call into him late on a Saturday, when the shop was closed...with a small problem and

★★★★★ 5.0 James Casey · Jan 2018

This was my best experience with a contractor in our new home. Harold the owner was very good at walking the system explaining to me what he was looking at so I learned the system as a new owner. He found the issue, not only fixed that, he fixed a couple other small items. The entire time explaining to me what he was doing so I could look after the system unless there was a major issue. I was not clear how much I would be charged above and beyond the fee to come out. He charged me for the one hour with no add on charges or fees. We plan on living here for a long time and T & H Mechanical have earned our business for certain. Highly recommend!
