When your furnace stops heating, short-cycles or starts making a new noise, we find the fault and tell you what the repair costs before we start. We work on gas, electric and oil furnaces, plus boilers.
If your furnace is old and the repairs keep adding up, we'll lay out the numbers for a replacement next to the numbers for a repair, so you can decide with both in front of you. For a new system, see our gas furnace installation page, or read furnace repair for the faults we fix most.
Comox winters are mild and wet, with few days that drop far below freezing. A heat pump does its best work in that range, so it can heat your home through most of the season and cool it in July and August.
We install three setups:
Every install starts with a room-by-room CSA F280 heat loss and heat gain calculation, so the heat pump keeps up in January and doesn't run oversized in spring. See heat pump installation and mini split installation for system details. If your current heat pump isn't keeping up, go to heat pump repair.
If you live near the water in Kye Bay, Point Holmes or along Lazo Road, salt air reaches your outdoor unit. Rinse the outdoor coil with a garden hose a few times a year and keep shrubs and fencing a couple of feet back so the unit can breathe.
A heat pump or mini split gives you heating and AC from one system, and we also install and repair central air conditioners. Read more on AC installation, AC repair and AC replacement.
A yearly tune-up before the heating season catches worn parts, dirty burners and airflow problems while they are still cheap to fix. On a heat pump, we measure system performance, clean the coils and test the defrost cycle, which matters in a damp climate like ours. Book your tune-up on our heating maintenance page.
If your heat goes out, call us at 778-909-9393. See emergency HVAC repair for what to check while you wait.
Homestar is listed on the CleanBC Better Homes contractor directory. Two provincial programs can lower the cost of a heat pump: the CleanBC Better Homes and Home Renovation Rebate Program, and the Energy Savings Program for income-qualified homeowners. Amounts and eligibility change through the year, so check the current offers at betterhomesbc.ca before you book. Ask us about them when we quote your system.
Every Homestar install in Comox starts with a room-by-room CSA F280 heat loss and heat gain calculation. It tells us how much heat each room loses in winter and gains in summer, so the system fits your house.
Once the system is in, we commission it and measure the results before we call the job done:
We treat your house as one system, with the equipment, ductwork and building working together, and we measure how the whole home performs.

Heat pumps work well in Comox winters. Temperatures stay mild and rarely drop far below freezing, which keeps a heat pump in its efficient range for most of the season. For the colder snaps, a cold-climate model or a hybrid system with a gas furnace backup keeps your home warm. A room-by-room CSA F280 heat loss calculation shows which setup fits your house before you buy.
Switching from oil to a heat pump starts with a room-by-room CSA F280 heat loss calculation and a look at the ductwork you have and how you heat your home now. From there we quote the full switch, including what happens to the old furnace. CleanBC Better Homes has offered rebates for oil-to-heat-pump switches, so check betterhomesbc.ca for the current amounts.
Once a year is the right schedule for most Comox homes, ideally in early fall before the heating season. Heat pumps run for both heating and cooling here, so they work more hours than a furnace and benefit from the yearly check. Book it on our maintenance page.
A furnace that won't start often comes down to the thermostat, a tripped breaker or a clogged filter, so check those first. If the furnace still won't run, call us at 778-909-9393. If you smell gas, leave the house and call FortisBC from outside.
Our service area runs from Comox across the valley to Courtenay, Cumberland, Royston, Union Bay, Merville and Black Creek, and north to Campbell River. See every town on our areas we serve page.
Call 778-909-9393 (Monday to Friday, 8 am to 4 pm, Saturday by appointment only) or book online. A Red Seal technician will come to your home in Comox and give you a quote before any work starts.
