Boiler Repair questions, answered by experts

A home radiator lasts anywhere from 15 to 20 years with proper maintenance. If your unit is approaching the 15-year mark, it’s a good idea to inspect your system and consider upgrading the radiator to a new one. Older models are less efficient over time compared to newer, energy-efficient radiators.

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.

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.

To bleed a radiator, first turn off the heat to the system. Then, lay a towel under the valve, open the bleed valve, wait 20 to 30 seconds for air to escape, and gently close the valve. You should repeat this process for every radiator you have in your home. Once your radiator valves have all been closed carefully, you can turn them back on.

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.
