Real Customer Story: The Moore Family in Newmarket
In September 2025, a Newmarket resident, J. Moore, noticed loud noises coming from his old furnace. After a temporary repair didn’t solve the issue, he contacted Constant Home Comfort, a trusted HVAC company serving the GTA and surrounding regions for over 20 years.
Our technician inspected the system and recommended replacing it with a 70,000 BTU Lennox furnace — offering better efficiency, quieter operation, and long-term reliability.
The Moores qualified for the Enbridge Home Efficiency Rebate Plus (HER+), receiving $3,500 back after installation — covering almost half of their investment. Now, their home stays warm and quiet all winter long, with lower utility bills.
