HVAC Contractor | Toronto

Welcome to the L.B. HEATING & AIR CONDITIONING Web Site.

Established in 1972, our company is pleased to sell, install, maintain, repair and service heating ventilation and air conditioning (HVAC) systems across the City of Toronto.  We specialize in Older Toronto homes especially in the Junction, High Park, Bloor West Village, and Parkdale area.  If your home is over 75+ years old then we are your best source for all your HVAC needs. Get in touch with us and we'll be happy to help you with great advice and experience to make you feel more comfortable in your home.

Attention all valued customers:

We’ve been closely monitoring the widespread effects of COVID-19 and it has become obvious the situation is untenable for us to continue providing non-essential HVAC services until further notice. In the meantime, we will be available for any no heat or emergency services. We will not be providing maintenances, gas line work, barbecue connections, fresh air intakes, et cetera.

We are fully connected to our systems and expect to maintain an emergency line during this period as best as possible. The best way to communicate is by phoning our main office line 416-762-1291 answerable by office staff and an answering service.

Temporary Suspension of Rebate Program

Effective immediately, Enbridge and Union Gas have suspended the rebate program until April 6, 2020.

The rapid evolution of COVID-19 has prompted Enbridge to re-evaluate the work performed by our employees and service providers. We need to ensure that we limit human contact as much as possible for our team and our customers, while also maintaining safe and reliable operations. As a result, all in-home energy audits for HER program are suspended until at least April 6th to ensure that the health and safety of our employees, customers and business partners continue to be our number one priority.  

  • For customers interested in participating in the HER program:
    • Inspectors will schedule their initial energy audit to a date/time after the suspension has been lifted.

Please note that the HER program requirement to complete your audits and submissions within 120 days will be waived until June 30th, 2020 
Please note that for NO Heat customers, If the D audit falls within the time program is suspended, Enbridge will allow an extension beyond 30 days to perform an initial energy audit. 

Rest assured...once this COVID-19 is under control, the program will be back up and running. 

Dear Customers,

As a friendly reminder, any customer who has previous maintenance done to their appliance by us is immediately registered in our Labour Insurance Program. This program entitles you to a 20% labour deduction on any service work done in the calendar year
