How do you compete with the likes of Mr Cool? Me and my father replaced his 15yr old heat pump/air handler in his house a few months ago. Took us a weekend and about $4500. That was a 3 ton unit. Similarly we installed a 1.8 ton split unit in a new house. About $2500 for that one. Both were complete kits including thermostat and required no refrigerant install as everything was pre charged. The 3 ton was even 21 seer if I remember correctly. These Mr Cool units sell locally at Home Depot and other places.
