Alliston and Angus homes, at a glance

New Tecumseth is a mix of growing subdivisions, older village homes and farms. Here's what that means for your heating and cooling.

  • HomesSubdivisions, village homes and farms

    Newer builds in Alliston and Angus, older houses in Beeton and Tottenham, and farm properties out on the concessions.

  • Builder equipmentReaching replacement age

    Many subdivision homes still run the furnace and AC the builder put in. Those basic single-stage units tend to wear out around the same time across a street.

  • UtilitiesAlectra Utilities plus Enbridge

    Alectra Utilities supplies hydro, and Enbridge Gas serves the towns. Farm properties off the gas line often heat with propane or oil.

  • WeatherWind across open farmland

    Nothing slows the wind between Alliston and Angus. Exposed homes lose heat faster, so we size with that in mind.

Who calls our HVAC company in Alliston

Different households, same goal: a system that works and a price that makes sense.

Families in newer subdivisions

The builder-grade furnace is getting noisy and the AC struggles in July. We replace both with quieter, more efficient equipment and give you one price for the pair.

Budget-conscious first-time owners

You need heat now, not a lecture. We show the repair cost next to the replacement cost and let you pick, with financing if it helps.

Shift-work households

Book a visit any day of the week, from 8 in the morning to 8 at night Monday to Saturday, or 10 to 5 on Sunday.

Farms and rural homes on propane

Out on the concessions, a heat pump can cut propane use sharply, and propane homes can claim up to $7,500 in rebates.

Furnace installation in Alliston: signs it's time

Not every old furnace needs replacing. These are the signs that usually mean it does, and the ones a repair can fix.

  • The builder furnace is at the 15-year mark and getting loud

    Builder furnaces are usually single-stage, so every start is a full-power roar. A newer two-stage model spends most of its time on its low setting, which means fewer noisy starts, more even rooms and a smaller gas bill.

  • The furnace and air conditioner were installed together years ago

    Replacing both at once usually costs less than two separate visits and gets you a matched system. If the AC is near the end too, a heat pump can take its place and help with heating as well.

  • Every repair quote seems to come with a surprise

    Our quotes list the parts and labour for the agreed scope, and that number holds. If we find something new, we explain it and price it before touching it.

  • Upstairs is warm in summer and the basement is cold in winter

    That's usually airflow, not the equipment. We check the duct sizes, returns and dampers and balance the system before recommending anything bigger.

  • The farmhouse burns through propane every winter

    Pair a cold-climate heat pump with the propane furnace you already have. You'll call the propane truck far less often, and the furnace only wakes up when it's truly cold.

  • The furnace dies in January and the budget isn't ready

    Our emergency line runs evenings, weekends and holidays. If it has to be replaced, interest-free terms or an open loan from 2.99% OAC keep the new furnace from wrecking the month's budget.

  • Snow drifts bury the outdoor unit on the windward side of the house every winter

    Open farm country between Alliston and Angus piles snow against whatever faces the wind. A heat pump that sits in a drift can't breathe, and it burns time and power in defrost. We mount the new unit on a raised stand on the sheltered side of the house, clear of the roof edge and the snowblower's path, and leave room for defrost water to drain away before it freezes.

  • Sound familiar?

    Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.

How the monthly payment works on an Alliston furnace replacement

A new furnace rarely arrives at a convenient time, so here's how the payment side works before you need it.

  • The quote shows the full installed price for the agreed scope. That number is guaranteed.
  • If a heat pump is part of the job and your home qualifies, the rebate estimate is shown as its own line, with pre-approval filed before the install.
  • You choose between 0% interest over 3, 6 or 9 months and an open loan from 2.99%, both on approved credit. The open loan suits a bigger job that you'd rather spread over a longer term, and it can be paid off early.
  • The lender approval usually happens before install day, so the work isn't held up by paperwork.

Rates are subject to lender approval, and we'll show you the monthly figure for each option on the same page as the cash price, so a household in Angus or Tottenham can compare them at the kitchen table without a calculator.

Frequently asked questions

How much is a new furnace in Alliston?

A high-efficiency gas furnace in Alliston starts from $3,300 installed. The final price depends on the size of the home and the installation requirements, and we lock it in with a guaranteed quote.

Is it smarter to swap the furnace and AC together?

If both are about the same age, usually yes. One install visit costs less than two, and the equipment is matched to work together.

Do you offer financing for HVAC in Alliston?

Yes. Alliston homeowners can pick an interest-free plan over 3, 6 or 9 months or an open loan starting at 2.99%, subject to credit approval.

Can you do AC repair in Alliston, or only replacements?

We do both. If a capacitor or a refrigerant leak is the problem, our licensed refrigeration techs fix it, and we only suggest a new unit when the repair doesn't add up.

My Angus home's AC is dying. Should I get a heat pump instead?

Often, yes, especially when the AC needs replacing anyway. A heat pump cools like an AC and also heats through much of the winter, with your gas furnace as backup.

Will you come out to Beeton or Tottenham?

Yes. All of New Tecumseth is in our area, Beeton, Tottenham, Everett and Loretto included, and you choose the visit date.
