I live in an older house that features central heat and air: a natural gas furnace from 1984 that the A/C contractor deemed had a leaking exchanger last winter and shut the valve to it. The A/C is from 1994 and starting to have problems cooling.
I am wondering if it would make more financial sense to replace the whole system with a heat pump?
The alternative is to replace the furnace and A/C all at once, but I would be interested in hearing people's opinions about this - especially considering where I live, south of Houston near Galveston.
It gets cold here, but rarely below freezing and if so, not for long. We use some oil filled electric radiators when it gets that cold, but not so often.
I am not trying to be cheap, just wanting to spend my money wisely since a replacement is long overdue and I want to make sure I do this correctly.
