I have a ten year warranty when my central air unit was put in back in September of 2015. It is August 18th of 2025 as of now. My compressor, capacitor, and an electric box went bad on my unit. We called, and a tech was out the next day, replaced all bad parts, with no charge. I will use this company for any HVAC work I need done in the future. Thank you guys. Mike.
Highly recommend Wally at TDH Mechanical. He installed a new AC and furnace after ours died and it was more reasonably priced than the other quote we received (by a lot). Wally took the time to explain the equipment and maintenance to me and was communicative throughout the process. Highly recommend.
I’ve been using TDH for 8 years for multiple units- new system installs and repairs and maintenance. Their technicians are polite, professional, and thorough. Installs are clean and complete. Steps are taken and advice is provided to prevent other issues before they occur. On this particular job, Mark provided quick analysis on a 22 year old furnace. The repair would’ve been minimum 1/4 the cost of a new furnace. A 22 year old furnace is definitely aged out. After receiving a replacement quote, we scheduled a new install two days out. Alfredo and Vidal arrived at 7:30 am right on time on a Saturday morning, worked steadily for four hours removing the old, installing a new drain pan with water sensor and platform with a new furnace on that. I mention the drain pan because this is a good practice/ should have been done last install due to it being on the second floor. I can’t tell you how many friends have come home to overflows from their evaporator coil drain because the line gets clogged. That water leaking down with flow to the floor below, wrecking hardwood and drywall along the way. Anyway, that attention to detail is a clue that quality is job one at TDH. Warranty issues have been handled on two previous installs with no questions asked. While their pricing isn’t the lowest in the business, the value is there- price is what you pay but value is what you get. I know that many aren’t but I am personally more interested in value over time than pricing. I appreciate it very much!
TDH installed a Trane/Mitsubishi mini split system in our home in November 2022. I received multiple quotes for the project, and TDH was the most competitive. I appreciated that Bernie provided us with a quote the same day - other contractors took weeks, or never responded at all. After working with a third party to provide a load calculation to determine exact system sizing (pretty close to what TDH initially proposed), we specified a 5 ton system with 2 outdoor condensers and 6 indoor heads. Installing this type of system in a vintage brick structure is very labor intensive. Thankfully, George and the other installers were exceptional; they were very detail-oriented throughout the process. His experience and expertise with the system and various components was apparent. He took the time to discuss all of the equipment and line set locations with me as the project progressed, and he was very polite and considerate of keeping our interior spaces minimally disturbed. Post-installation, TDH quickly addressed the few questions I had. Overall, a great experience, and I would recommend TDH for anyone's HVAC needs, especially mini split systems.
Communication- the company is very responsive in all inquiries and came the next day after we call for a free estimate. Bernie came, he is nice enough so we got convince on how he explains the pros and cons of the producr and services offered by their company. Good Value/Budget-they can work on to your budget and offer 18mos. 0% interest, Jackie helps us to work with the bank for financing. Professional/On-time - Jose and Andres came on time on the day of installation, they uninstall the old unit and put up the new unit,,,,,they even clean up and make sure leave everything si in place before they leave. Lastly Thanks to their boss Tim, he communicates well to his team, and answers all our question in real time...Our transaction went smooth and everything goes well. I highly recommend this company.
