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!

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 Peterborough and the surrounding county
Peterborough has everything from century homes in the Avenues and East City to newer builds in the west end and around Trent University. Many older homes still have chimney-vented water heaters and original furnaces, so we check venting and sizing before we quote.
Outside the city, in Lakefield, Bridgenorth and much of Selwyn and Otonabee–South Monaghan, many properties are on private wells. If that's you, start with a water test. A UV sterilizer is the usual choice for bacteria, and hard water may also call for a softener.
