Furnace Service in Vancouver
A furnace service is a safety inspection that happens to also improve efficiency. The efficiency is the part that gets advertised; the combustion and heat exchanger checks are the part that matters, and they are why this is annual rather than occasional.
Pre-season inspection checklist
A proper service covers the burner and flame characteristics, the heat exchanger, venting and its terminations, the blower and motor, safety controls and limits, thermostat calibration, and the condensate drain on a high-efficiency unit. That work is done by a ticketed gas fitter or licensed HVAC technician.
Book it in late summer or early autumn. The first cold snap of November is when every furnace in the region is asked to work hard for the first time in six months, which is both when faults appear and when nobody is available. A service in September is a calm appointment; the same call in November is an emergency rate.
Filter types and change intervals
This is the maintenance you do yourself, and it is the single most valuable one. A clogged filter starves the blower, which reduces airflow across the heat exchanger, which makes the system run hotter and work harder — and in the worst case trips high-limit safeties.
Basic one-inch fibreglass filters want changing roughly every one to three months. Thicker pleated media filters in a proper cabinet last considerably longer, often six months to a year. Households with pets, allergies or ongoing renovation dust need them more often than the packet suggests. Write the date on the edge of the filter in marker when you fit it.
Carbon monoxide testing
Carbon monoxide is colourless and odourless, and the symptoms — headache, nausea, dizziness, fatigue — are easy to attribute to something else. The signature that should make you suspicious is symptoms that improve when you leave the house and return when you come back.
Have working CO alarms on every level, particularly near sleeping areas, and test them rather than assuming. If an alarm sounds, get everyone outside first and call the gas utility or emergency services from outside — do not spend time investigating. A technician testing during a service is checking the appliance; the alarm is what protects you the rest of the year.
Repair vs. replace by age
Gas furnaces commonly run fifteen to twenty years and often longer with maintenance. Past roughly fifteen, weigh a significant repair against replacement, factoring in that efficiency has improved substantially — an older mid-efficiency unit costs meaningfully more to run than a modern one.
One diagnosis should generally end the discussion rather than start it: a cracked heat exchanger. That is a combustion-gases-into-your-air fault, the part is expensive, and on an older furnace the sensible answer is almost always replacement. If you are told you have one, it is entirely reasonable to seek a second opinion — it is also the diagnosis least worth ignoring.
What this costs
$420–$780 service · heat pump installs $11,000–$24,000
Annual service and diagnostics are a fixed visit. Installs are quoted after a heat-loss assessment — an undersized system is a more expensive mistake than the price difference between quotes.
Materials are always separate from labour and passed on at cost. Quotes are free and written, and the full rate card is published rather than given out on request.
Common questions
When should I book a furnace service?
Late summer or early autumn, before the first cold week of November when every furnace in the region gets asked to work hard at once. That week is when faults surface and when availability disappears. A September appointment is unhurried and cheaper than the same call as an emergency in November.
How often do filters need changing?
Basic one-inch fibreglass roughly every one to three months; thicker pleated media in a proper cabinet often six months to a year. More often with pets, allergies or renovation dust. Write the date on the filter edge when you fit it — a clogged filter starves airflow and makes the whole system run hot.
What are the signs of a cracked heat exchanger?
Possible indicators include soot marks, a yellow or flickering flame where it should be blue, and people in the house getting headaches or nausea that ease when they leave. None of these are self-diagnosable — a cracked exchanger needs a licensed technician to confirm. If a CO alarm sounds, get everyone outside and call the gas utility from outside first.
