"I called to get a third estimate on replacing my residential boiler. I was looking at replacing it because other contractors had advised that the cost of repairs was too high; repairing a 20 ye old boiler didn’t make economic sense. Gilles sent Justin over the next day, so very quick service. Justin gave me a ballpark price to replace it, which was more in line with what I thought was fair. He also gave me a very fair price to repair it — about a third of what the other contractors quoted. A good chunk money, but a much better option right now. Comparing what the three contractors told me, I’m confident that Justin had it all coveted. He then allowed me to video him, explaining what he did and what I should expect and look out for. He also sold me on their annual maintenance plan, which is a bargain because it includes evaporative cooler startup and shut down."

"Kieth came out multiple times to address the issues I had. Eventually I had him replace my old Furnace, water heater and AC, in addition he cleaned several drains as well. He explained in detail how the project would be competed as well as a time line. He not only finished sooner than expected but did a phenomenal job, he left the work area cleaner than what I had it. I would highly recommend Plumbing Tree for any home services, Even with current circumstances of money being tight I did get multiple other bids and Plumbing Tree was more than fair!"

"The work done by this company, especially Roman & Josh, was professional, and nothing short of amazing. Overcoming a few obstacles, they went above and beyond to make sure the project was done the "right way". Their workmanship, cleanliness, and overall positivity says a great deal about their training. Management and ownership should be commended because everyone's efforts are noticed. Thank you so very much for a job well done."

FAQs for boiler or radiator heating system service projects in Denver, CO

Radiator heat can be more expensive to install than forced-air systems due to the materials and technology involved. However, radiators often provide superior warmth and can improve indoor air quality by not circulating allergens. While the upfront costs may be higher, the enhanced energy efficiency and lasting performance can make radiators a worthwhile investment for a comfortable home.

If one radiator in your home isn't heating up, it might be due to trapped air or a blockage from debris or sludge. Your pro can bleed the radiator to release any air pockets. If that doesn't work, it might need a thorough cleaning or professional inspection. Regular maintenance helps prevent these issues and keeps your heating system running smoothly.

If your radiator is making banging, clanging, or hissing noises, it might have trapped air or loose parts. Your pro will likely start by bleeding the radiator to release any air pockets. Next, they’ll check that all valves, brackets, and pipes are securely tightened. Adding insulation can also help reduce noise. If the sounds persist and your pro recommends it, a replacement may be necessary.
