Boiler Repair FAQs, answered by experts

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

In many cases, yes, you can fix a radiator without replacing it, and it’s usually more affordable to do so. Radiators are relatively simple fixtures that shouldn’t run into many issues, but when you do have a radiator problem, the solutions typically require minimal materials and just an hour or so of labor. The only issue that demands a full radiator replacement is if the unit itself is cracked. This typically occurs only with aging systems.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

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.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
