Furnace repair, installation, and replacement in Tillsonburg.
Furnace work is our most-called service in Tillsonburg. We handle furnace repair when a system has stopped heating or is misbehaving, furnace replacement when the repair-vs-replace math tips toward new, and furnace installation in new builds or major retrofits. Every quote starts with diagnosis — we don't write estimates before we've seen the unit.
Tillsonburg's housing stock drives the kind of furnace work we see most often. Older homes often need full replacements as 25-30 year old units reach end of life. Newer subdivisions usually call for repair work on systems hitting mid-life issues like flame sensors, igniters, and condensate drains. Rural acreage tends to mix gas and propane setups that need careful sizing per home.
For Tillsonburg homeowners weighing repair vs replace, the $5,000 rule is the simplest starting math. For current Oxford County pricing on new furnaces, see our furnace cost guide. For furnaces misbehaving right now, work through the no-heat checklist first.

Air conditioning, ductless mini-split, and heat pump work in Tillsonburg.
Cooling work in Tillsonburg runs across three buckets: AC repair when a system fails in summer, AC replacement when the unit hits end of life or runs R-22 refrigerant, and new installations of central AC, ductless mini-splits, or cold-climate heat pumps. We size every install with Manual J — not square-footage shortcuts — so the system actually fits the home.
Most pre-2010 ACs in Tillsonburg run R-22 refrigerant, which is phased out and now expensive to service. When an R-22 system leaks, replacement is usually the better economic call. For homes due for AC replacement anyway, current Ontario rebates make the cold-climate heat pump conversion math compelling — typically $5,000-$10,000 off a heat pump install when programs stack.
If your AC isn't cooling right now, work through our AC troubleshooting checklist first. For the broader repair-vs-replace conversation, see our AC repair-or-replace guide. For heat pump pricing and rebate math specific to Oxford County, see our heat pump cost guide and the Ontario rebate stacking guide.

HRV, ERV, humidifier, and indoor air quality in Tillsonburg.
Modern Tillsonburg homes — anything built post-2000 with tight air sealing — often need mechanical ventilation to breathe properly. We install HRVs (heat recovery ventilators), the right choice for Oxford County's cold dry winters; ERVs in the rare case humidity control demands them; whole-home humidifiers to address dry winter indoor air; and indoor air quality equipment (filtration, UV) when symptoms call for it.
Not sure whether your home needs an HRV or an ERV? Our HRV vs ERV comparison walks through the decision for Oxford County climate.

We run Manual J heat-load calculations on every install (not square-footage rules of thumb), so the new furnace is sized to your home, not oversized for safety margin.

Yes — central AC repair, replacement, and installation, plus ductless mini-splits and cold-climate heat pumps.
