Boiler Repair questions, answered by experts

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

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.

Regular inspections, filter replacements, and professional tune-ups keep the system running efficiently.

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.
