Learn more about our Services

LB Heating & Air Conditioning Co. has now been proudly servicing Metro Toronto for over 50 years! There isn’t a corner of the 416 that LB Heating & Air Conditioning Co has not installed, serviced or maintained a HVAC appliance. We’ve been to Hogs Hollow, Regent Park, High Park, Mimico, the Beach, Leaside, Rexdale, Rosedale, Swansea, Thistletown, Cabbagetown, Parkdale, Liberty Village and Forest Hill. You name it and we’ve been there. Heck, we’ve even done work in Port Credit. That is why we specialize in old homes (older the better!).

Indeed, our office and warehouse are located in the Junction in a historic 100+ year old building. The result is we have comprehensive experience and extensive knowledge servicing all kinds of HVAC equipment regardless of the age and type. It doesn’t matter if its hot water or hot air, we do it. We know old Toronto homes as if we’ve lived in them. That has given us the edge over our competition when it comes to understanding and anticipating our clients’ HVAC needs. There is no doubt that old homes have their charms but their challenges too.

That is why we say: You’ll be Comfortable with Us!

Furnaces Service and Repair Toronto

LB Heating & Air Conditioning Co. started in 1972 by Bob Lausic. He came from a Sheet Metal background as a Union Forman at a Sheet Metal Shop in the late 60s. Gas as a Home Fuel was starting to gain prominence in the early 70s as more homeowners were inquiring about the use of gas in their homes. With his dedication to hard work and thirst for knowledge, Bob applied his new Gas License to help with the conversion of many Toronto homes from oil to gas heating.

With his Sheet Metal experience, he was able to convert many old Toronto homes with poor ductwork into updated and properly fitted duct. With his innate desire to help people and passion for satisfying his clients, he built this company to where it stands today. These virtues have now been passed on to the second generation at LB Heating & Air Conditioning Co. where we apply the same virtues and high standards that were set by our founder 50 years ago.

We are proud to be an independently owned and family operated business.
