Help TigerDunes! Heat-Pump Replacement Needed?
I have taken on the task of researching new systems for my grandmotherÃ¯Â¿Â½s home. Her home was built about 35 years ago. Because the home is located in a rural area we do not have gas, so the systems upstairs & downstairs are heat-pumps which are pretty foreign to me. They are the original systems from when the home was built, Rheem heat-pumps. The systems have worked well all these years however they are extremely inefficient at this point. My grandma is 85 & has some pretty severe health problems so she runs the heat non-stop once it starts to get cold here in Northern California. The electricity bill in January last year was over 2K for the month. We have some other electrical consumers on the property (Well system, Pool, Electric water Heaters) but I have singled out the heat-pump with the help of a Kilowatt meter as the BIG culprit. ItÃ¯Â¿Â½s now time to do a complete replacement on the system downstairs, (She only lives downstairs now). I believe the investment will pay for itself over time perhaps in a season so IÃ¯Â¿Â½m looking for the most efficient heat pump system that money can buy (especially in heat mode). Maximum HSPF needed. I love the American Standard Hvac line, just did a complete new system (Gas) at my motherÃ¯Â¿Â½s home last month that you helped me with & we couldnÃ¯Â¿Â½t be happier with it. Thank you so much for all your help (TigerDunes)! I have located a very good contractor to sell us the equipment & perform the install but I want to insure that I am getting a fair deal as well as getting the right system for our a application. I would really appreciate your opinions/expertise, Thank you in advance, this site is really great!
Ã¯Â¿Â½2 Story Home in Northern California (Pretty mild Climate that we have)
Ã¯Â¿Â½2,200 Square Feet of living space downstairs with a crawlspace (Downflow System, not sure yet if the duct work needs some attention)
Ã¯Â¿Â½Ceilings are pretty low 9Ã¯Â¿Â½ at the highest.
Ã¯Â¿Â½The home gets sun in the summer months most of the day.
Ã¯Â¿Â½Insulation in the home is decent, Doors are air-tight.
Ã¯Â¿Â½Windows have all been replaced 5 years ago with more efficient ones.
HereÃ¯Â¿Â½s what I put together so far from the AHRI site:
3933754 Active Systems HERITAGE 16 AMERICAN STANDARD 4A6H6060E1 4TEE3C10A1 55000 12.00 16.00 51000 9.00 34200
ItÃ¯Â¿Â½s a 5-ton system; I think we need the additional BTUÃ¯Â¿Â½s for heat to quickly & efficiently warm-up the house for her? Also, does this system need a heat-strip? If so what size they make several variations for these air handlers (I donÃ¯Â¿Â½t understand the heat-strip thing)? What do you think?
God Bless America!
