I have a York H4DH060S06A 5-Ton unit installed in 2000
that is 12 SEER and I'm starting to wonder if it is worth upgrading to
a more efficient 18-21 SEER model out there.
I just bought this home in Brea, CA in Sept 2011, and the temps will get up in the 100's in the summer. I'm just trying to pre think my plan if this unit croaks or try to save on power if upgrading to a 21 SEER unit is worth it.
The house is a 2,900 Sqft multi-level home.
If you had this unit would you consider upgrading, or just repair it if/when it
I installed a NEST thermostat so I can track how much time my A/C is running, and I will soon have a TED 5000-C energy detective installed
so I can see my power usage.
