Should You Repair or Replace Your System?
Here are the most common signs it is time to invest in a modern high-efficiency HVAC replacement rather than sinking money into endless repairs.
System Over 12–15 Years Old
Major components like compressors and heat exchangers are reaching end-of-life and losing efficiency rapidly.
Repair Cost Exceeds 50% of Value
When a repair estimate (such as a blower motor or compressor) costs nearly half the price of a brand new unit with warranty.
System Uses Outlawed R-22 Freon
R-22 refrigerant is phased out and extremely expensive to recharge if your old cooling system develops a leak.
Cracked Heat Exchanger Warning
Cracked furnace heat exchangers allow carbon monoxide to leak into your living areas—a direct health emergency.
Maximizing Available Rebate Grants
Ontario energy efficiency rebates offer up to $6,500 for qualifying heat pump and hybrid furnace retrofits.
Loud Rattles & Continuous Run Cycles
Old single-stage units blasting at 100% capacity loudly and failing to maintain stable temperature.

What Our Customers Say
See how ON TIME HVAC made the installation process smooth, stress-free, and cost-effective.
"We got quotes from 4 different HVAC companies in Kitchener. ON TIME HVAC had the best price, explained the heat pump grant clearly, and finished the install in one day. We received a $5,000 rebate check!"
"The installers were so respectful of our home. They laid drop runners everywhere, cleaned up every piece of scrap wire, and took the time to show us how to use the smart thermostat. Outstanding team!"
"We bought out our old rental water heater and had ON TIME install a Navien tankless system. Endless hot water and no more paying $48 every month to a rental company. Best decision ever."
