What should I check first when a Duncan heater stops working?

Start with the thermostat and breaker panel before assuming the heat pump or furnace itself has failed. A tripped breaker, an incorrect thermostat setting, or a dead backup battery causes more no-heat calls in Duncan than an actual mechanical failure. If the outdoor unit is coated in ice, shut the system off and let it thaw rather than running it continuously, since that risks burning out the compressor. When the basics check out, and the system still won't run, one of our service professionals will walk through refrigerant levels, electrical connections, and defrost cycles.

How do I know if my heater needs repair or a full replacement?

Age and repair cost relative to replacement cost usually settle the question. A heat pump under ten years old with a failed capacitor or contactor is almost always worth repairing. Once a compressor fails on a unit past its expected service life, or a furnace heat exchanger develops a crack, replacement becomes the safer long-term choice, since a cracked heat exchanger risks carbon monoxide leaking into the home. We'll walk you through the diagnostic findings during your Duncan heater repair call, and you'll decide whether a repair or a full heater replacement fits your budget.

What other services does Aire Serv offer in Duncan, BC?

Heater repair and replacement is one piece of a wider lineup for Duncan homes and businesses. We also handle AC repair and AC replacement for the warmer months, plus heat pump installation for homeowners switching a furnace-only system over to combined heating and cooling. Indoor air quality work and dryer vent cleaning round out our regular Duncan calls. Every service runs on the same flat-rate pricing model, so you'll know the cost before any work begins.

What areas near Duncan does Aire Serv serve?

Our Duncan calls typically come from North Cowichan and the Mill Bay area, and our Greater Victoria team runs the same route down to Saanich , Langford , and Esquimalt on any given day. Dispatch schedules by route density rather than treating outlying towns as an afterthought, so response times stay consistent no matter which stop the call comes from. If your address falls outside our regular Cowichan Valley run, ask when you call, and we'll confirm coverage before booking a visit.

How quickly does Aire Serv respond to a heater emergency in Duncan?

Emergency heater service in Duncan runs 24 hours a day, including holidays, and a live dispatcher answers instead of routing you to voicemail. Winter no-heat calls take priority over routine maintenance visits, since a failed heat pump in freezing rain differs from a scheduled tune-up. Most Duncan emergency calls receive an on-site service professional the same day, though arrival windows depend on how many other emergency calls are already in the queue. There's no overtime surcharge for after-hours or weekend heater repair.

How do I schedule heater repair or replacement service in Duncan, BC?

Reach out through our online request form or by phone, and mention that you're located in Duncan so that dispatch can route you to the right service window. We'll ask what system you have — a heat pump, ductless split, or gas furnace — and whether you're dealing with no heat at all or reduced performance, so the service professional arrives with the right parts on the truck. Heater repair and replacement bookings in Duncan typically get same-week availability outside of emergencies. Contact us today to get a visit on the schedule.

The Aire Serv Advantage

More About Our Heater Repair in Duncan, BC

Aire Serv of Greater Victoria is the same Victoria HVAC contractor that services heat pumps, ductless splits, and gas appliances throughout the Cowichan Valley, and Duncan calls get the identical diagnostic process every other stop on the route receives. A service professional checks refrigerant pressures, defrost board function, and electrical connections on heat pump systems, since most homes in this region run on heat pumps rather than gas furnaces. Compressor short cycling, iced-over outdoor coils, and a reversing valve stuck in cooling mode are the most common heater failures we find in Duncan's damp winters. For the rarer gas furnace calls, we test the igniter, flame sensor, and gas valve against the manufacturer's specs before replacing anything.

Replacement becomes the better option when a heat pump's compressor fails out of warranty or a furnace heat exchanger cracks, since patched repairs on either component rarely hold up through a full Vancouver Island winter. We size replacement heat pumps to your home's square footage and duct layout, rather than swapping in a like-for-like unit. Duncan's older housing stock, especially homes built before the 1990s with original ductwork, often needs duct sealing or a modified refrigerant line set to run a new heat pump efficiently. We handle that assessment during the same visit, so you're not scheduling a second appointment to find out your ducts need attention, too.

Why Call Aire Serv of Greater Victoria for Heater Repair in Duncan, BC?

Every Aire Serv service professional working in Duncan carries EPA refrigerant certification and follows the same diagnostic checklist on every call, whether it's a mid-morning tune-up or a 2 a.m. no-heat emergency. We back every repair and installation with the Neighbourly Done Right Promise®, so you're covered if something isn't right after we leave. Emergency service runs 24/7 across the Cowichan Valley, and a dispatcher, not a voicemail, answers when your heat goes out on a Saturday night.

Beyond heater repair and replacement, our Duncan HVAC pros also handle heat pump installation, ductless split systems, and indoor air quality upgrades built for wildfire smoke season. We price every heater job upfront before work starts, so there are no surprise labor charges once the panel is off the unit. If your Duncan home needs its heat restored or a full system evaluation, schedule a heater repair appointment today, and we'll get a professional on the way.
