Town, country and century homes in Stouffville

Whitchurch-Stouffville covers a lot of ground. In town, newer subdivisions have modern high-efficiency equipment that is starting to reach replacement age. Near Main Street, older and heritage homes may have tight basements and older chimneys. Out in Ballantrae, Musselman's Lake and the rural areas, many homes rely on private wells.

For well-water homes, protecting both your family and your new water heater starts with a water test. UV sterilization treats bacteria, and hard well water may also need a softener designed for well water. For every home, we check venting and gas supply before we quote.

  • UV water sterilizers for private wells
  • Furnace and water heater replacements in newer subdivisions
  • Careful installs in older homes near Main Street

Great experience with Mr. Heating and Home. Clear and helpful communication throughout, talked me through options, cost/benefit and answered every question. Installation was on-time, clean and with licensed professionals. And the best part, beat Costco pricing and let me pay by Amex!

We had pleasant experience with Mr. Heating and Home. They installed a heat pump, electrical furnace, thermostat and a new electrical panel. Everything went smooth. No complaints. They laid down a red carpet and were respectful, professional.

I had an old air system taken out and a new heat pump put in. These guys did a great job and were quick installing the new heat pump. When they left everything was clean and tidy. I would recommend Mr.Heating and Home team to anyone looking to upgrade! Great team!

Installed a water heater and water softener. There was issue during installation with a blocked pipe from my old water heater. I initially was upset but they resolved everything and made sure I was happy in the end.

Stouffville Furnace & Water Heater FAQs

Do you install in Ballantrae and Musselman's Lake?
Yes. We serve all of Whitchurch-Stouffville, including rural areas. Call 905-418-2629 to confirm timing for your address.
I'm on a private well. What should I install?
Start with a water test. A UV sterilizer is the usual choice for bacteria. If your water is hard, you may also need a softener designed for well water, so call us and we'll recommend the right combination.
Can you replace a water heater in an older home?
Yes. In older homes we check the chimney and venting carefully. If the chimney is no longer suitable, a power-vent or tankless heater is often the best solution.
What is included in your installed price?
The equipment, standard installation by licensed, insured technicians, removal of the old unit and a 10-day money-back guarantee. Any extra work is quoted before we start.
