    I've come to significantly value the feedback provided in these forums for learning and better understanding how my HVAC system works and issues that can be encountered with it. In the time I've...

    It is definitely an "older" furnace with a direct drive blower (the blower was changed probably 10 yrs ago or so). The blower was originally belt-driven, but I suspect that it was changed with the...

    Will a new thermostat be more efficient?

    I've got a Dual Energy HVAC system (oil furnace & Carrier heat pump) with a dual electric rate from the power company. This means that when the temp is warmer than -12C my rate goes down 25%, but...

    Fair enough. But right now, the temp is hovering around the freezing point, and the house is sitting at about 27% RH. I turned on the blower activation, and the fan has been running for the last...

  8. How to match a Contractor on the map to a user on this site?

  22. Is the cost of running a Geothermal heat pump less than an air-based heat pump?

    I live in Montreal, Canada and have an oil furnace and standard heat pump. My heat pump runs until -12C at which point the oil furnace takes over full-time. I have a dual-energy electric...
