the heat exchanger went out on our furnace at our summer home. can we still run the central air, or do we have to wait till our new furnace is instlled this fall?
Yes you can still use the central air as there will be no negative effects because of the cracked heat exchanger...the only concern I would have is if it has a standing pilot(pilot burns all the time) I would turn off gas so there woud be no possibility of any carbon monoxide being pulled into the home by the air traveling past the heat exchanger...
There is no reason that you cannot use your a/c. The furnace not working won't be a factor until this winter.
Run the central air, but replace the heater when the time comes. Cracked heat exchanger can cause carbon monoxide gases, but not on cooling.
