Time To Replace Some Heat Pumps-Or At Least One

Rental home of 4000 square feet (two story) in climate zone 3 in California has the original heating/cooling system installed when new in 1979. Tenants are paying $1,000.00 in electric bill monthly, so time to upgrade the system is long overdue. Summer days often hit 100 degrees and it can get chilly during the winter.

There must be 50 brands/sub-brands of heat pumps/air handlers out there, pretty overwhelming trying to decide what to do. The home has nothing going for it structure-wise: vaulted ceilings in three upstairs bedrooms, huge glass sliding doors all over the house, and a lot of windows. Fireplaces upstairs and downstairs.

One 3.5 ton unit serves one floor and a 4.0 ton unit serves the other floor. Units have to run constantly for the retired tenants to keep comfortable, either warm/cool. Spring and fall not so bad.
