Eager to find a solution to high energy bills, the Kimballs switched from fossil fuels to heat pumps and also made energy efficiency upgrades. The system has already paid for itself and the household saves $1,500-$2,000 per year. “The systems have exceeded our expectations in all regards," the Kimballs state. Their motivation for installing heat pump technology was fueled by a dying oil fired furnace and a desire for air conditioning. They installed an air source hot water heat pump, a four ton geothermal system with a horizontal loop field, and a ductless air source heat pump to heat and cool the office above the garage.
Mr. Kimball did all the installation himself, drawing on many years of experience as a HVAC contractor. In spite of this success, Mr. Kimball recommends having installation done by a professional company, noting it is a challenging process and important to install correctly. Although the excavation process tore up the lawn, all damage was remedied within two years. They intend to install solar photovoltaic (PV) panels as well as an Energy Recovery Ventilator (ERV) in the near future.
