Frequently Asked Questions About Boiler Repair

Why is my boiler losing pressure?

Pressure loss is usually caused by a water leak somewhere in the system, a faulty pressure relief valve, or bleeding radiators. Our technicians can find and fix the source of the pressure drop.

What does it mean if my boiler is kettling?

Kettling — a rumbling or banging sound like a kettle — is usually caused by limescale buildup on the heat exchanger. It reduces efficiency and can cause damage if not addressed.

How long do boilers last?

A well-maintained boiler can last 15-25 years. If your boiler is over 15 years old and experiencing frequent issues, we can help you evaluate whether repair or replacement is the better investment.

Do you repair combi boilers?

Yes. We service and repair combination (combi) boilers from all major manufacturers. Combi boilers provide both heating and hot water, so a prompt repair is especially important.

“Lloyd HVAC met and exceeded my high expectations. From the office staff and owner, to the technician everybody was pleasant and helpful. My AC unit did not turn on in the spring. They were able to help provide me with the information I needed and send out a technician quickly. While the technician was here, the owner was even willing to run to the store to pick up a part for us. I highly recommend using this company.”
