"Lenny and his crew installed a new Lennox furnace for us. The team is courteous and professional. Lenny found that our old humidifier was installed at the wrong place because of the difficult duct work. He went above and beyond his responsibility and installed the new humidifier at the correct position. I greatly appreciate his honesty and utmost professionalism. It is no wonder that his company gets consistently high reviews."

"Excellent. on time arrival, neat work and cleanup. Right price for well-known brand system and installation. Ken is a very good communicator by phone or email. Brother Joe is very experienced and did the job - really focused on the work - doesn't spend time chatting on the phone while trying to work. Answered all my questions. Had my new system up and running by afternoon. We are contracting with Ken for a new furnace - the present one has a rusted heat exchanger, revealed when old system removed. He proposed the right price for equipment to serve our needs."

"I had the best experience with H2Bros Plumbing and Heating. I hired them to install Navien combi unit to replace my old boiler and water heater. Genaro and Javin were very knowledgeable, professional, and polite from the start. They did an awesome job by installing all the needed parts by the code and very neat. Even though I know some plumbing companies cut corners and not install all additional components that recommended by Navien. Very reasonably priced for the job they did. I would definitely recommend them for similar jobs or any plumbing and heating projects. Please see the photo of the finished job for yourself."

"We called because we had no heat or hot water. Steve came within a few hours, assessed the situation and replaced a clogged valve. The cost was very reasonable and he made sure to clean up after himself. He took a great deal of time to answer my questions and explained to me the costs and advantages of updating our furnace as well as alternatives to oil heat, We have used this company many times (as we have a very old home) and Steve is always very professional and friendly."

Install Boiler questions, answered by experts

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

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.
