Local know-how

Heritage downtown homes to new Brooklin builds

Downtown Whitby and Port Whitby have many older homes, where we often find chimney-vented water heaters and older mid-efficiency furnaces. Upgrading these usually means planning new venting, and we check that the chimney is still suitable for any appliance left in it.

North in Brooklin, newer homes are tightly built and often have high-efficiency equipment already. There, owners usually call us to replace a failed water heater, add an HRV or improve filtration. Rural properties around Ashburn may be on wells, where UV water treatment is worth considering.

  • Venting upgrades for older downtown homes
  • HRVs and air filtration for newer Brooklin homes
  • UV treatment for rural well-water properties

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.

Whitby Furnace & Water Heater FAQs

Do you serve Brooklin?
Yes. We install across Whitby, including Brooklin and the rural north. Call 905-418-2629 to check same-day availability.
My older Whitby home has a chimney. Can I still get a high-efficiency furnace?
Yes. High-efficiency furnaces vent through the wall with plastic pipe, so the chimney isn't needed for the furnace. We'll also make sure your water heater still has a safe way to vent.
How much does a tank water heater cost installed?
Our gas tank water heaters are installed from $2,195, including standard installation and removal of your old tank.
Do you offer a guarantee?
Yes. Every installation includes our 10-day money-back guarantee, plus the full manufacturer's warranty, which we register for you.
