Heating and Cooling in Cornwall, Priced Plainly and Explained Clearly

Lower winter bills without the sales pitch

If your Cornwall HVAC question is really a money question, you're in the right place.

We explain the rebate in plain terms, give you a guaranteed price, and keep gas furnaces running safely for homes that aren't ready to switch.

  • Baseboard to heat pump conversions, sized room by room
  • Rebate rules explained in plain language before you sign
  • Furnace repairs by TSSA-certified gas technicians
  • Pay it off at 0% over 3, 6 or 9 months, on approved credit

Four things we weigh on every Cornwall quote

Cornwall homes have their own mix of heat sources and costs. These shape every plan we put on paper.

  • Local hydroCornwall Electric

    Electric-heated homes feel every rate change. We use your actual bills to estimate what a heat pump would save, not a national average.

  • Natural gasEnbridge Gas

    Gas-heated homes can still add a heat pump for cooling and mild-weather heat, with the furnace kept as backup.

  • ClimateCold winters, humid summers

    St. Lawrence summers are sticky and Eastern Ontario winters bite. A heat pump covers both seasons with one outdoor unit.

  • Plain-language quotesEvery line item spelled out

    Cornwall is a bilingual city, and the paperwork should be easy for everyone at the kitchen table. Bring a family member to the visit, or have them read the quote with you.

Cornwall heating bills and breakdowns we help with

Most calls here come down to cost or reliability. Here's what we see and what we do about it.

  • Baseboard heat makes January the priciest month of the year

    Every kilowatt a baseboard draws comes out as one kilowatt of heat, never more. A cold-climate heat pump moves heat in from outdoors instead, so it uses much less power for the same warmth through most of the winter. Electric-heated homes also sit in the higher rebate tier, up to $7,500.

  • You don't trust the rebate math someone showed you

    We walk through it line by line: the heat pump size, the amount that size can qualify for, and the pre-approval that has to happen before installation. If a number depends on program terms, we tell you, because those terms can change.

  • Some rooms stay cold even with the baseboards turned all the way up

    Old baseboards in drafty rooms fight a losing battle. A multi-zone ductless system puts a head in each main area, and we look for big air leaks before sizing so you don't pay for capacity you won't use.

  • The gas furnace keeps locking itself out

    Dirty flame sensors, failing pressure switches and blocked vents are the usual suspects. Our TSSA-certified gas technicians find the real fault, quote the repair before starting and tell you honestly if the furnace is near the end.

  • Window air conditioners rattle all summer and barely cool the bedrooms

    A ductless heat pump cools quietly in summer and heats in winter. In a baseboard home, that one install retires the window units and takes over most of the baseboard load.

  • You'd like to switch, but the upfront cost is the sticking point

    Between the rebate for eligible homes, 0% financing for 3, 6 or 9 months and open loans from 2.99% OAC, many households can spread the cost. We lay out each option side by side so you can compare.

  • The house has an electric furnace and ducts, so baseboards aren't the issue

    An electric furnace is a bank of heating strips in a cabinet, and it costs about the same to run as baseboards. The good news is the ducts are already there. A cold-climate heat pump with a Midea electric air handler drops onto the same ductwork, the strips become backup for the coldest nights, and the home still qualifies for the electric-heat rebate tier.

  • 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 rebate changes the real price of a Cornwall heat pump

The rebate isn't a discount at the till. It's a payment that comes to you after the install, and the amount depends on the size of the heat pump and how the home was heated before. Here's how we show it so there are no surprises.

  • Line one: the installed price for the agreed scope, which is guaranteed
  • Line two: the rebate amount your heat pump size and heating fuel may qualify for, marked as an estimate until pre-approval comes back
  • Line three: the net cost after the rebate, and what that looks like at 0% over 3, 6 or 9 months on approved credit

Electric-heated homes in the East End, Riverdale and Le Village sit in the higher tier, up to $7,500. Enbridge gas homes commonly see up to $2,000. Pre-approval has to be in place before the install, program terms can change, and we say so on the quote in plain words.

Frequently asked questions

How much can a Cornwall home with electric baseboards save with a heat pump?

Savings depend on your house, your hydro rates and how the heat pump is sized, so we estimate them from your own bills. In mild and moderate weather a cold-climate heat pump gives far more heat per kilowatt than baseboards, and that's where most of the savings come from.

Do electric-heated homes in Cornwall get the bigger heat pump rebate?

Yes. Homes heated by electricity can qualify for up to $7,500 toward a cold-climate heat pump through the Home Renovation Savings Program, based on the heat pump's size. The pre-approval needs to come through before any equipment goes in.

Can I keep my baseboards after the heat pump goes in?

Yes, and many people do. The baseboards stay as backup for the coldest nights or for rooms without a head, and they simply run much less often.

Do you still repair gas furnaces in Cornwall?

Yes. Our TSSA-certified gas technicians repair and maintain gas furnaces in Cornwall, and we'll tell you plainly whether a repair or a replacement is the better spend.

Can someone in my family go over the quote with me?

Of course. Our quotes are written in plain language with every item listed, and you're welcome to have anyone you like join the visit or read it over before you decide.

Is there an HVAC company in Cornwall that serves Long Sault and Ingleside?

Our crews serve Cornwall, Long Sault, Ingleside, St. Andrews West and nearby communities, working from our office in Stouffville. We set visit dates with you directly.

What does it cost to replace baseboards with a heat pump in Cornwall?

A ducted cold-climate heat pump in Cornwall starts from $5,500 installed, before a rebate of up to $7,500 for electric-heated homes. A multi-zone ductless system for a baseboard home without ducts is priced by written quote, since the number of heads sets the figure. Installed pricing depends on size and installation requirements.
