"Had some annoying issues with our thermostat that’s been on and off for the past month. At last, something just seemed broken and the thermostat didn’t turn on. I called Behold, and within an hour, they had one of their guys out to our place to fix everything. Kendrick was amazing (and super kind) and got everything squared away within an hour. Super grateful. Will definitely use them anytime I have HVAC issues."

"Initially I requested an estimate for a plumbing project already in progress with some challenges. Keith responded immediately to get details and schedule to come out to look at what was needed. He proposed a solution that eliminated any impact to walls or tile to replace old valves and faucets. He and his team completed the work on time and were neat and professional and results were better than I expected. There was no damage at all to what was old tile. I subsequently had him assess an old water heater and decided to replace it. It had to go into a very small areas and be upgraded to code and he was able to solution the replacement to fit perfectly in the limited space. Previously on the project we had noticed a periodic odor of gas but no one had verified a source. Keith identified a leak in the area of the furnace right next to the water heater. We had decided to upgrade the furnace and AC and again Keith and his team were able to get an order in quickly, get the install done exactly as committed and fixed the gas leak in the process. Based on the quality of work performed in each case and the expertise of the team I hired Plumbing Tree again to assess an old furnace and AC at my primary residence. The furnace had been failing at the end of the winter but I waited for summer to replace and it had deteriorated and was not safe. Keith evaluated and gave me two options and was able to get the order in immediately after I decided to go ahead. He scheduled the install within a few days. His crew was on time and completed the install of furnace and AC in one day. Again they were neat, efficient, described all the changes from the old furnace and thermostat to the new and answered all my questions. Everything has been functioning just as I expected for both heat and AC. I recommend Plumbing Tree for these services based on quality and reliability - also cost was competitive and the team they used had the expertise required. Additionally they were easy to work with and I plan to use them again on another project. Thanks Keith and team- I appreciate the quality work!"

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

"Did not end up using them to fix the overall issue, as their quote was higher then all others we received. That being said, technician was polite and provided an informative second opinion."

"I signed up 3 years ago to the Swan Club, which includes yearly inspections of our furnace, ac, and plumbing. Mark recently inspected our air conditioning system. After purchasing an HVAC system from Swan, we joined the Swan Club, which includes yearly inspections. Yesterday our service technician was Mark. He was extremely thorough and professional, and and walked us through the whole system with pictures and comments. He could not have been more helpful. Thanks Mark"

Boiler Repair FAQs, answered by experts

Yes, it is generally safe and effective to turn off radiators in unused rooms to save money on heating costs. This practice is especially beneficial with older heating systems. However, you should avoid cranking up the thermostats on the remaining radiators to compensate, as this can lead to higher heating bills and increased wear and tear on your system. While some HVAC specialists argue that modern, efficient boilers are designed to heat the entire home and work best when all radiators are on, turning off radiators in unused spaces still reduces the total amount of hot water your system needs to produce.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
