It's looking like I might have to replace a very expensive and very old HVAC system in my house (it's a double AC/heater unit that does central heat and air for the whole house). They seem to run about $8000. Ideally I'd switch to separate units, one for AC and one for heat.
Does anyone have some experience getting grants or rebates from the state of California or PG&E or somewhere similar for energy efficient upgrades? I think this would qualify since the unit is so old.
I'm mainly wondering about the process and what it takes to get approved to do this.
