Frequently Asked Questions

Just like furnace maintenance, your boiler should be maintained yearly. Annual maintenance from one of our expert technicians keeps your boiler running right. It’s a chance for a qualified boiler technician to make any minor adjustments necessary and an opportunity to catch any small repairs before they become bigger issues.

The main difference between boilers and furnaces is how they heat your home. Boilers use water, whereas furnaces use air. With a boiler system, the boiler heats your home by sending hot water to your radiators, keeping your home warm through radiant heating. Furnaces, on the other hand, heat your home using forced air which is distributed through a vent system.

How often your boiler should be replaced depends on a variety of factors, but you can expect to replace your boiler about as often as a furnace or every 8 to 15 years. The model of boiler you have, the type (electric or gas), and maintenance can all influence the life of your boiler. If you think it might be time to replace your boiler, contact us for a free in-home assessment.
