Furnace Repair & Installation in Whitby & Durham Region

Durham Furnace Installation & Repair

Whitby & Durham Region furnaces are working hard for at least half the year, and when one fails, homeowners need a technician who shows up fast and diagnoses the problem honestly. Walchuk Heating & Cooling has served Whitby, Oshawa, Ajax, Courtice, Bowmanville, Port Perry, and Port Hope for close to 15 years, with two locations in Whitby and a 24/7 emergency line for the calls that can't wait until morning.

Furnace Repair

The problem: no heat or weak airflow, short cycling (turning on and off repeatedly), strange noises like banging or squealing, a pilot light or ignition system that won't stay lit, rising energy bills with no change in usage, and air blowing cold instead of warm are the most common reasons homeowners call us about a furnace. It rarely fails without warning.

The fix: our technicians walk through the most common versions of these problems, and what they usually mean in our furnace repair questions and answers, then diagnose your specific system before recommending anything.

Repair or Replace?

Not every furnace problem means you need a new system, and not every quote for a new system is the right call. We diagnose before we recommend, which is exactly what turned a $6,000 replacement quote into an $89 fix for one Oshawa homeowner. For a fuller breakdown of when repair makes sense versus when replacement actually saves you money long-term, see our guide on deciding to repair or replace.

Furnace Installation

The problem: a furnace that needs frequent repairs, is nearing the end of its expected lifespan, or simply can't keep up with your home anymore are the usual reasons homeowners start looking at replacement instead of another repair call.

The fix: when replacement is the right call, we install furnaces from major residential brands and size the system properly for your home rather than your old ductwork. Every installation is backed by our one-year workmanship guarantee and our 100% satisfaction guarantee, on top of the manufacturer's own equipment warranty. Our technicians are licensed (TSSA #000229172, HRAI #114449) and fully insured (WSIB #5318422), and we're BBB accredited. Not sure what type of furnace fits your home? Our guide to choosing the right furnace walks through the options.

Furnace Maintenance

Annual maintenance is the cheapest way to avoid an emergency repair call in January. Our preventative maintenance visits cover the checks that catch small problems before they become no-heat calls, and one of the simplest things you can do between visits is stay on top of your filter. See our guide to furnace filters and MERV ratings if you're not sure what to buy, or read more on what a proper maintenance plan should include.

Financing

Furnace replacement is a real expense, and we offer lease-to-own financing so a failed furnace doesn't have to mean an impossible bill all at once. See our breakdown of how lease-to-own financing works before you decide.

Frequently Asked Questions

How do I know if I should repair or replace my furnace? It usually comes down to the age of the unit, the cost of the repair versus the cost of a new system, and how often you've had to call for service recently. We diagnose the actual problem first and give you a straight answer, not an automatic upsell, that's the approach that turned a $6,000 replacement quote into an $89 fix for one Oshawa homeowner. See our full guide on repair vs. replace for more.

What are the most common signs a furnace needs repair?
