| I need to replace my 20 year-old, 4-ton heat pump. My local utility did a heat loss calculation for my home and says that I need a 3.5 ton heat pump with 12.5 kw heat strips.
This is the system suggested by a contractor. Is this setup good, or should I ask for something else? 18 SEER

| Location? What size heat strip do you have now? 13 KW is a little light for a 4 ton especially during a defrost cycle to temper the air. Looks like AHRI matching number #3540158. Has demand defrost which is great! IMO |

| Pacific coast. Fairly mild climate, temps running averaging between 37-76 through the year. Some years it does snow (occasionally over a foot). Temps have gotten to 0, but actually rarely get as low 10, and at the other end not very often are they over 90. I wondered the same thing on the heat strips. I believe that I was told the power available for old strips was 20kw. Is the thermostat one you are familiar with? Thanks! |

| I would want a 15 KW at the minimum staged in 5 KW increments or perhaps 2 7.5 KW strips. Discuss with dealer. Thermostat mdl number looks like a HW VP IAQ model which is one of the best. Verify with dealer. IMO |
