FAQs

General & Maintenance

  • How often should I change my furnace filters?
    • For standard 1-inch filters, every 30 to 90 days. If you have pets or allergies, aim for the 30-day mark. High-efficiency media filters (4-5 inches) can last 6 to 12 months.
  • Why is my AC running but the house isn’t getting cooler?
    • This is often due to a dirty air filter, blocked outdoor condenser coils, or a refrigerant leak. Check your filter first—if it’s clean, it’s time for a professional inspection.
  • Is it necessary to have annual HVAC maintenance?
    • Yes. Much like your car, an HVAC system needs a “tune-up.” Annual service prevents 80% of breakdowns, maintains your manufacturer’s warranty, and keeps your energy bills lower by ensuring the system runs at peak efficiency.

Upgrades & Efficiency

  • What is the difference between a Heat Pump and a traditional AC?
    • A standard AC only cools your home. A heat pump is a 2-in-1 system: it cools in the summer and reverses the process to heat your home in the winter—all without burning fossil fuels.
  • Will a heat pump work in Hamilton’s cold winters?
    • Absolutely. Modern Cold Climate Air Source Heat Pumps (ccASHPs) are designed to provide efficient heat even when temperatures drop to -25°C. We often install them as “hybrid systems” alongside your furnace for the ultimate backup on the coldest nights.
  • What is a SEER2 rating, and why should I care?
    • SEER2 measures how much energy your AC uses to cool your home. The higher the number, the lower your electricity bill. As of 2026, high-efficiency units typically start at 16 SEER2.

Cost & Rebates

  • How much does a new AC or Furnace cost in Ontario?
    • A new central AC typically ranges from $3,500 to $7,500 installed. A furnace is similar, usually $4,000 to $8,000. Prices vary based on your home’s size and the system’s efficiency rating.
  • Are there still rebates available for HVAC upgrades?
    • Yes! While the old Greener Homes Grant is closed, the Home Renovation Savings (HRS) program and municipal loans like Better Homes Hamilton offer up to $7,500 in rebates or 0% interest financing for qualified heat pump installations.

Troubleshooting (The “Check Before You Call” list)

Check the Filter: A clogged filter can cause the system to overheat and shut down for safety.

My furnace isn’t turning on. What should I check?

Check the Thermostat: Is it set to “Heat” and is the temperature higher than the room?

Check the Batteries: Does your thermostat need new ones?

Check the Switch: Is the furnace power switch (usually looks like a light switch near the unit) turned ON?
