All 3: Professional, Courteous, On-time
We already knew the system was leaking, it was very old and needed replacement. Wally went through options and picked a system based on our feedback and home measurements. Quote was timely, apt was set up (non-emergency) within 5 days, even tho there were Tstorms and a heatwave. It was a tight fit, in an old house. All was done professionally. Price was better than most. Quality was also better than most. Very Happy with Wally and TDH

Excellent service and price
This is my second installation by Wally. Everything once again was top notch and good pricing. I have now have had two high efficiency Trane furnaces and an A/C installed by Wally. I came back due the excellent work and pricing. Strongly recommend them. Furnaces are produced in USA (no other brand is 100% American made).

We've been using TDH for years and have been very pleased with the quality of service. We have them service our two furnaces as well as two tankless water heaters. It is easy to schedule an appointment with TDH, and it's nice to have the same technician every time. Kris understands our system and is always here within our appointment window.

I completed a project involving the installation of a new Trane two-stage variable speed furnace, paired with two-stage Honeywell thermostat. The Trane furnace was chosen for its energy efficiency and quiet operation, ensuring optimal performance and comfort. The Honeywell thermostat was selected for its advanced features, including precise temperature control and user-friendly interface. The installation process began with a thorough assessment of the existing system to ensure compatibility and optimal placement of the new equipment. The furnace was carefully installed, with attention to detail in connecting the necessary ducts and ensuring proper ventilation. The Honeywell thermostat was then installed and programmed to work seamlessly with the new furnace, providing the client with enhanced control over their heating system. The final step involved rigorous testing to confirm that both the furnace and thermostat were functioning correctly and efficiently. This project resulted in a
