Furnace Installation & Repair
High-efficiency furnace installation, replacement, and same-day repair across the Greater Toronto Area. TSSA-licensed technicians you can trust.
Furnace Installation & Repair in the GTA
When your furnace stops working on a cold Ontario night, you need a team that answers the phone and shows up fast. Complete Air Solutions has been installing, repairing, and maintaining residential and commercial furnaces across the GTA for over 25 years.
Every furnace project starts with a proper load calculation so your new unit is sized correctly. An oversized furnace short-cycles and wastes energy. An undersized one struggles on the coldest days. We take the time to get it right.
Our licensed technicians work with all major brands and service every furnace make and model. From emergency ignition failures to full high-efficiency replacements, we handle the job start to finish.

Furnaces FAQs
Answers to the most common questions.
How long does a furnace last?
Most furnaces last 15 to 20 years with regular maintenance. If yours is over 15 years old, making frequent repairs, or your energy bills are climbing, it is time to consider replacement.
What size furnace do I need?
Furnace size depends on your home's square footage, insulation, windows, and climate. We perform a detailed load calculation to recommend the right size. Oversized furnaces waste energy and short-cycle. Undersized ones cannot keep up on the coldest days.
How much does a new furnace cost in the GTA?
A standard high-efficiency furnace installation typically ranges from $3,500 to $7,500 in the GTA, depending on the brand, size, and complexity of installation. We provide free, no-obligation quotes.
