Frequently Asked Questions

When should I service my furnace?

Most manufacturers recommend an annual tune-up before the heating season — late summer or early fall in most of Canada. A licensed technician will inspect the heat exchanger, clean the burners, check gas pressure, and replace the filter.

How much does HVAC installation cost in California?

Costs vary widely by system, home size, and province. A new central AC typically runs from a few thousand dollars; a high-efficiency furnace or cold-climate heat pump is more. Ask a licensed technician for a written quote that includes equipment, labour, permits, and any rebate processing.

Should I repair or replace my old air conditioner?

If your AC is 12+ years old, uses R-22 refrigerant, or the repair quote is more than half the cost of replacement, replacement is usually the better long-term value. A licensed technician can run a load calculation and quote both options.

What's the difference between SEER and AFUE ratings?

SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency for AC and heat pumps — higher is better. AFUE (Annual Fuel Utilization Efficiency) measures heating efficiency for gas, oil, and propane furnaces, expressed as a percentage. Higher AFUE means more of your fuel becomes heat.

Do HVAC technicians need to be licensed in my province?

Yes — gas work in particular is regulated everywhere in Canada. Always ask for a gas-fitter ticket (G2 or G1 in Ontario, equivalent elsewhere), refrigerant handling certification (ODP card), and proof of insurance before any work begins.

How often should I change my furnace filter?

Standard 1-inch filters: every 1–3 months during heating and cooling season. Thicker 4-inch or 5-inch media filters: every 6–12 months. If you have pets or allergies, change more often. A clogged filter wastes energy and stresses the blower motor.

What is a heat pump and is it right for my climate?

A heat pump is an electric system that moves heat instead of generating it — providing both heating and cooling. Modern cold-climate heat pumps work efficiently down to -25°C, making them viable across most of Canada. Many provinces and the federal Greener Homes program offer rebates.

How long does an HVAC system typically last?

Furnaces: 15–20 years. Central AC: 12–15 years. Heat pumps: 12–15 years. Ductwork: 30+ years if properly sealed. Annual maintenance extends life on every component. Replace before failure to avoid emergency-rate pricing.
