What Oakville houses tend to need
Smithville Heating Cooling works from Smithville and books visits to Oakville for furnace repair and replacement, air conditioning, heat pumps and seasonal tune-ups. Because it is a longer drive than our usual rounds, visits are planned with you ahead of time. Tell us what your system is doing, and you will see a written price before any part goes in.
Oakville is a longer drive from our home base in Smithville, so visits there are planned with you rather than fitted in between local calls. That suits much of the work Oakville households ask about: tune-ups booked before the season turns, replacements that need a proper look at the house first, and heat pump quotes that take some measuring.
What we do for Oakville homes
- Furnace repair when the heat stops, the furnace keeps shutting itself off or the blower runs with nothing warm coming out
- Furnace installation and replacement, sized to the house rather than to the label on the old unit
- Furnace and AC maintenance, ideally booked before the first cold weeks or the first hot ones
- Heat pumps, including hybrid set-ups that share the work with an existing gas furnace
- Air conditioner repair and air conditioning installation, central or ductless
Who does the work
Work is performed by TSSA-certified gas technicians. Work is performed by 313A refrigeration and air conditioning mechanics. Whatever the job, the price is written down and you approve it before anything is fitted.
Booking a visit
Use the contact page or ask for a quote and describe what the system is doing. A few details help us arrive with the right parts: roughly how old the furnace or air conditioner is, whether it vents through plastic pipes in the side wall or into a chimney, and any error light or code you can see. If you are weighing a replacement, have a look at our guide to rebates and tax credits first, since programs change and are worth checking before you decide.

Can I book a furnace or air conditioning tune-up in Oakville, or do you only come for repairs?
Tune-ups are a good fit for Oakville, because they can be planned around your schedule and ours. We look over the furnace or air conditioner, check the venting and condensate drain on high-efficiency units, and tell you plainly about anything that is wearing out. Book through the contact page, or read more on furnace and AC maintenance. If we find a repair is needed, you see a written price first.
The upstairs of our older house never cools down in summer. Is central air the only answer?
Not necessarily. Many older homes have ductwork that was sized for heat, or for a furnace that's long gone. Push cold air through those ducts and it often won't reach the top floor. A ductless system mounts heads in the rooms that need them and runs a small refrigerant line to an outdoor unit, so it doesn't depend on the old ducts. Work is performed by 313A refrigeration and air conditioning mechanics. See air conditioning installation.
Is there a tax credit or government rebate for a new furnace?
Programs come and go, and the rules change often. Federal and provincial support has tended to favour heat pumps and higher-efficiency equipment over a straight furnace swap. Some programs require an energy assessment before the work starts, so the order you do things in matters. We check which programs are open at the time we quote, so you know before you commit. Keep your invoices and equipment model numbers, since applications usually ask for them. Our guide on rebates and tax credits explains what to check.
