"This company was excellent all the way around. The staff member who contacted me was very nice and helpful. They were able to come out the same day (I did not have heat). They sent me a text message with a picture of the technician which I thought was an excellent feature. The technician, Jeff, was very nice and extremely knowledgeable. I would definitely hire them again because the work was top quality and the cost was fair and reasonable."

"David at Arrow Mechanical responded to my call on a Sunday morning. The Blower was blowing but no cooling. House was getting quite warm. He responded on a Sunday at regular pricing and completely restored the A/C within an hour, replacing a compactor on the outside unit. he found the problem quickly after thoroughly reviewing the furnace; then checking the outside unit. He is a very knowledgeable HAVC guy; also very courteous and polite...he definitely is a 5-star technician...if he keeps going, he'll be one of the best !"

"Steve arrived on time, quickly diagnosed the problem with the water heater, gave me options to fix/replace without trying to steer me to one option or the other, and answered my questions. I opted for replacement and he got the appointment set up for the next day so we wouldn't be without hot water any longer than necessary."

"I would recommend this company to everyone. Loved they are a small local, family owned business. Our furnace-boiler went out on a Saturday, Monday morning they were out and a quote in the afternoon. They made sure we had heat before Thanksgiving day. Very professional, knowledgeable, great craftsmanship. Best price on comparable equipment out of 3 quotes. Thank you!!"

Boiler Repair FAQs, answered by experts

If you don't clean a boiler, you may have higher energy bills or no heat. A dirty boiler is inefficient and can't properly maintain a heating system. It may break down more often due to corrosion or clogs from soot and oil buildup. Cleaning a boiler improves its performance. The cost to replace a boiler can be expensive, so keeping it clean is a cost-effective practice.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.

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.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.
