Does this site provide repair instructions?
No. It provides owner-safe observations and questions. Fuel, high-voltage, refrigerant, venting and internal appliance work belongs with qualified trades.
Is every page specific to Ontario?
No. The audience is Canada-wide. Ontario-specific rules are not presented as national rules, and local requirements must be confirmed.
Can the tools save my information?
No. Tool entries run in the current browser page and are not transmitted or backed up by this site.
Does a higher-efficiency model always lower bills?
Not necessarily. Climate, energy rates, load, sizing, installation, ductwork and behaviour all affect actual use.
How often should a furnace filter be changed?
There is no universal calendar interval. Inspect it, follow equipment and filter instructions, and consider household dust, pets, smoke and fan runtime.
Does the site sell leads or contractor referrals?
No. It does not operate a contractor marketplace or dispatch service.
