Hello,

Brand new to this forum and I'm hoping for some help.
We our A/C and heating is about 40 years old.
I'm looking to replace my equipment with something more efficient.

Here is my info:
Two stories (1750 sq. ft) - All electric home

My preference is to have something efficient but not top of the line. I'm looking for a good value and something reliable.
Something from brands like bryant, carrier, trane, york.

Thanks for your help!

Send me your address via e-mail ...

I can provide Heat Gains/Losses and
estimate the operating cost for 14, 16 and 18 SEER/ 9.5 HSPF.

Between 46'F to 81'F for 8,550 hours per year

I cannot imagine any significant heat load
and minimal cooling also.

Recent year Heating and Cooling Degree Days may lead me believe that energy costs are
higher than a review of the Design Temperatures might indicate.

I'll have to investigate further for more recent weather

In my opinion, CA has a very significant amount of " micro-climates" given proximity to ocean, mountains and further inland.

$ 0._ _ /Kw-Hr ?

................... Your utility

Your heating requirements seem to be MINIMAL. (< $200 annual [ given modern equipment ] )
Therefore, a heat pump would be appropriate based on Comfort.
Plus, a heat pump in S. CAL. would have a Very High average COP. [ > 4 Coefficient of Performance ]
I suspect the operating cost difference would be < $30 a year in the current rate $tructure.

The operating cost of a heat pump might be same (Or slightly less than) as a Natural Gas furnace
based on review of existing Average CA utility rate$ provided in www.eia.gov

PAST ELECTRIC RATES MAY not have a good correlation in the Future
given changes by the California P.U.C. in July 2015.

Apparently, LESS THAN 500 KW-HRS / month had better be a PRIORITY.

Something tied to the HVAC system.

I would select a Heat Pump dedicated to the Hot Water Tank.
____ I believe that keeps the Domestic Hot Water in the realm of _ KEEP IT SIMPLE _.
