Our central A/C and gas heating systems are the original for our home;now 19 years old. I know they have lasted beyond their life expectancy so I am obtaining quotes from different contractors.My question is what are the better brands and what are the ones to avoid?
The first contractor came by yesterday and they install Carrier. When I asked why his answers made sense but I don't really know.
Next week I'll have another contractor come by that installs for the Costco program and they install Lennox and I don't know much about it.
Any opinions are appreciated.
