Double air filter

Double air filter

A question asked quite often by my customers is, “How often should I change my furnace filter?” Another popular question is, “Why do you carry so many Band-Aids?” but that’s another story (sheet metal joke).

Can I have cavity wall insulation?

About a third of all the heat lost in an uninsulated home escapes through the walls. Heat will always flow from a warm area to a cold one.

In general, houses built from the 1990s onwards have wall insulation to keep the heat in, but if your house is older than that it may not…

Rheem condenser fan motor

Rheem condenser fan motor

I think you re out of luck on OEM parts for that unit. I ve tried to look at this question as to how it would be applicable to anyone s unit. On the nameplate, you re given the horsepower and you know it s 220v; the only question is what RPM it needs to be. I think it s reasonable to assume that if it s a 1/6hp motor, it s not any faster than 1, 200 RPM. It is possible that it s…
