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!

Water Heater Installation in Mississauga
Hot water out in Mississauga, or tired of paying rental fees? We install gas tank water heaters from $2,195 that you own outright, and haul the old one away, often the same day you call.

Fresh, filtered air all year. Lifebreath HRVs, Lennox HEPA filtration and UV lights connect to your furnace ductwork and quietly clean the air in every room.
Serving every corner of Mississauga
Mississauga has a wide range of homes, from older bungalows and backsplits in Port Credit, Clarkson and Cooksville to the large subdivisions of Erin Mills, Meadowvale and Churchill Meadows built in the 1980s, 90s and 2000s. Many of those newer homes still have their original furnace or a rented water heater, and both are now reaching replacement age.
Thinking about getting out of a water heater rental? Buying your own tank or tankless heater usually pays for itself within a few years compared with monthly rental fees, and you own it from day one. We handle the swap and haul the old unit back for you.
- Furnace and water heater replacements across Mississauga
- Rental water heater swaps to equipment you own
- Tankless upgrades for larger family homes
10-Day Money-Back Guarantee
Not happy with your new equipment within 10 days of installation? Tell us and we'll make it right.
