About Us

On May 1, 2009, LDR was founded by Ljubo Jankovic and his sons, Darren and Robert. After 20+ years with a large national firm, Ljubo set out on his own. He left with a vision for LDR: to provide the highest quality customer service with the best HVAC products on the market. With more than 50 years of experience in the HVAC industry, we set out to offer you a simple, straightforward option for your needs—highly technical HVAC solutions guaranteed to work for you.


We have fully qualified and certified technicians. We are certified by the Technical Standards and Safety Authority and have been since we first opened our doors for business. The TSSA is Ontario’s public safety regulator mandated by the Government of Ontario to enforce provincial safety regulations and enhance public safety. We have a G1 (Gas Technician 1), the highest level attainable through TSSA. We have a Red Seal Journeyperson Sheet Metal Worker (308A) certified through the Ontario College of Trades.
