I'm trying to decide between a standard A/C unit or a heat pump when I replace my home furnace & A/C unit this Spring. An HVAC contractor mentioned that the electric rates for heat pumps were lower than for an A/C unit. I got the HP rate schedule from my utility co. which states that the HP has to have it's own meter installed. The rate schedule states that "The duration and frequency of interruptions will be determined by the company. The direct load control device will be cycled on a schedule of 15 minutes on and 15 minutes off normally for six hours with a maximum of eight hours per day. Interruptions will normally occur on high demand weekdays during summer months."
Wouldn't this damage the heat pump or shorten its life span if the power is cycled off & on like this while it's trying to run? There's no mention of whether the furnace is also wired to the HP meter so it cycles off & on, too. In either case, am I looking at possible damage to it also? Sounds pretty flakey to me.
BTW, the HP "reduced rate" is a joke - $6/month lower customer charge, but only $0.001 lower charge per KWH used, so it appears that an HP running off the existing meter would be the way to go.
House is approx 2400 s.f. in South Dakota, built in 1994, tight & good insulation.
Comments & advice would be appreciated. Thank you.
