Replacement Decision Guide

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.

Age 12-15+ Years

System Over 12–15 Years Old

Major components like compressors and heat exchangers are reaching end-of-life and losing efficiency rapidly.

Recommendation: Replace with an Energy Star certified unit to cut bills by 30%.
50% Rule

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.

Recommendation: Put the repair cost toward a new system with a 10-year warranty.
Phase-Out

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.

Recommendation: Upgrade to a modern R-410A / R-32 eco-friendly system.
Safety Risk

Cracked Heat Exchanger Warning

Cracked furnace heat exchangers allow carbon monoxide to leak into your living areas—a direct health emergency.

Recommendation: Immediate replacement required by TSSA gas codes.
Rebate Opportunity

Maximizing Available Rebate Grants

Ontario energy efficiency rebates offer up to $6,500 for qualifying heat pump and hybrid furnace retrofits.

Recommendation: Upgrade while government program funds are actively available.
Constant Noise

Loud Rattles & Continuous Run Cycles

Old single-stage units blasting at 100% capacity loudly and failing to maintain stable temperature.

Recommendation: Modulating variable-capacity unit for quiet comfort.

HVAC Installation FAQs

Clear answers to help you choose the best heating, cooling, and water heating systems for your home.

How long does an HVAC replacement take?
A standard furnace or air conditioner replacement is typically completed within 4 to 7 hours in a single day. Complete combo replacements (furnace + AC + duct modification) take between 6 to 9 hours. Our technicians work efficiently to ensure your home is never left without heating or cooling overnight.
How do heat pump rebates work in Ontario?
Eligible homeowners who install qualified cold-climate air-source heat pumps can receive substantial grants from provincial and federal energy efficiency programs. We guide you through the required pre-audit, supply AHRI-certified equipment, and help complete the post-installation grant submission.
Do you offer monthly financing or rent-to-own options?
Yes! We provide flexible low-interest financing plans with zero money down and open loan terms (pay off anytime with no penalty), making top-tier high-efficiency systems affordable starting from just $49/month.
What brands of equipment do you install?
We install industry-leading brands known for reliability, including Carrier, Goodman, Rheem, York, Amana, Bryant, Mitsubishi, and Navien. We match the brand and model best suited for your home's architecture and budget.
Will you remove and recycle my old furnace and AC?
Yes, 100%. We disconnect, safely recover all refrigerant in accordance with ODP/Ozone environmental regulations, remove the heavy metal units from your basement, and dispose of everything responsibly.
