All right, 10 burning questions. I'm going to answer them right now. Go ahead.
Heat pump or gas furnace?
I would say heat pump. If you have natural gas though, it may be more efficient to go gas.
Repair an older system or replace it?
If it's over 12 years old, you probably need to look at replacing.
High efficiency system or standard efficiency?
I'm gonna go high efficiency. Energy bills are not getting cheaper.
Smart thermostat or basic thermostat?
Smart thermostat. Not, not because it's like a gadget, but because you have more control.
Change filters monthly or when I remember?
I'm going to modify a little bit. Check your filters monthly. You probably don't need to change them monthly, but check them monthly.
One big return or multiple Returns?
Definitely multiple returns.
Zone system or one temperature for the whole house?
The zone system is the best when it's done right, and that's the best way to go.
Duct cleaning or better filtration?
Better filtration. Ducts aren't going to clean themselves.
Annual maintenance or run it until it breaks?
Annual maintenance.
Cheapest upfront option or lowest long-term cost?
I say lowest cost because again, energy bills are not going down.
