A new furnace and AC unit, installed with emails and calls answered along the way: a 2025 Google customer said this team completed that work in a timely manner. Theide Plumbing Heating HVAC LLC holds Massachusetts plumber license 4746-PL-C, active on the state registry. A 2024 customer said Theide installed a mini split heat pump at a fair price. A 2023 customer said Theide installed a new mini split in their apartment that worked through the winter and summer, and named the owner, Dave, and the technicians, Luis and Will. A 2023 customer in Worcester said Theide came out within a few days and replaced their garbage disposal in about 45 minutes. A 2023 customer said their technicians arrived on time and finished warranty-coverage replacement work on a leaking water heater in under 2 hours. A 2024 customer said they use Theide for their investment properties and their own home, and that during an emergency the owner called back within 5 minutes. A 2025 customer said Theide fixed a pinhole leak in a 2-foot pipe above their water heater by replacing only a 6-inch section. That 2025 customer said the remaining old pipe later sprang its own leak, and Theide again replaced only a 6-inch piece. A 2024 customer called the work pricey, saying a toilet install, a gasket replacement and some advice came to $845. A 2023 customer said they found no heat in the fall after Theide replaced their HVAC system, and were billed $703 when Theide came back and installed an electrical box. That 2023 customer also said later maintenance was billed at $380, including a travel surcharge. A 2022 customer who used Theide through a home warranty company said a central AC install left a leaking tray that damaged their ceiling, and that calls about fixing the heating went unreturned. A 2022 customer said that four months after paying a deposit for central AC, the company said it was too busy with big jobs and stopped returning calls. On Google it holds 3.8 stars from 33 ratings, and its Better Business Bureau grade is A+.
I had a great experience working with this team. They installed both a new furnace and AC unit for me and did an outstanding job. They were responsive to emails and phone calls, very transparent throughout the entire process, and took the time to answer all of my questions. The work was completed in a timely manner, and everyone I interacted with was exceptionally nice and professional. Everything is working perfectly—I couldn't be happier with the service!
Back in Jan 2023, Theide Plumbing fixed a pin hole leak in a 2 foot piece of pipe above my water heater. Instead of replacing the entire 2 foot section of defective pipe at that time, they only replaced a 6 inch section where the leak was (assuming to save the minimal cost of 1.5 foot of pipe). The remaining section of the old pipe that was not replaced sprang a pin hole leak last week. I called Theide to fix it and again they did not replace the entire 2 foot section, only a 6 inch piece where the leak was. Now I have a 1 foot section of old pipe I'm waiting to start leaking. And when it does I won't be calling Theide to fix it, I already paid them twice in a year to do the same job, which is still not done correctly. I spoke with the owner Dave, and he defended the workmanship as expected, however I believe the result of cutting corners speaks for itself. Avoid Theide.
Theide did a great job installing my mini split heat pump. They have friendly competent workers that do high quality work at a fair price.
These guys are old-school professionals. It's refreshing to get a job done right by competent individuals who take pride in their work.
I use Theide for all of my investment properties, as well as my own home. They are always professional, and respond right away when I call. I had an emergency this past weekend, and the owner called me back within 5 minutes. I highly recommend them!
