Boiler Repair questions, answered by experts

Generally speaking, yes, turning one radiator off does save some money, especially if the system is a little older—so long as you’re not cranking up the dial on the ones you leave on. But some HVAC specialists argue that keeping your entire system on ensures that your boiler stays efficient. After all, it’s rated to fit your home and heats the amount of water your heating system needs. This could be the case if you have a new system. However, turning radiators off in unused rooms lowers the amount of hot water you need.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

If you’re unsure who to call to fix your boiler, you have a few options. One is to call a dedicated boiler service. However, you can also call a plumber or HVAC technician for boiler repair services. These pros will have the tools, knowledge, and experience to fix common boiler problems.

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.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
