Hydronic (water-based) heating systems are common in many Toronto homes — especially older properties in East York, Danforth, Beaches, and North York. These systems use hot water circulated through baseboard heaters, radiators, or radiant floor piping to provide comfortable, even heat. When they develop problems, you need a technician who understands hydronic systems inside and out. Lloyd HVAC Services provides expert hydronic heating repair across Toronto and the GTA.

Frequently Asked Questions About Hydronic Heating Repair

Why is one radiator cold while others are hot?

This is usually caused by an air lock in the radiator, a stuck zone valve, a failed circulator pump for that zone, or a closed balancing valve. Bleeding the radiator often resolves air locks; other issues require professional repair.

Why is my hydronic system losing pressure?

Pressure loss indicates a water leak somewhere — in the piping, at a fitting, in the boiler, or through a faulty pressure relief valve. We use systematic testing to locate the leak.

How long do hydronic heating systems last?

Boilers typically last 15-25 years. Baseboard heaters and radiators can last 30+ years. Circulator pumps and zone valves usually last 10-20 years. Radiant floor piping (PEX) can last 50+ years.

Can you convert my hydronic system to forced air?

Yes, but it’s a major renovation. Many homeowners prefer to keep their hydronic system and add a ductless mini-split for cooling. We can advise on the best approach for your home.

“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.”
