A geothermal heat pump provides exceptionally energy-efficient heating and cooling, long life and low maintenance (Alan Watts Services and Water Furnace).
The heat pump and ducts are installed in a conditioned, unvented attic to eliminate energy losses and provide convenient access for maintenance and attic space.
A dual-fuel air source heat pump (American Standard) provides efficient cooling and heating. The high-SEER cooling has spine fin coils that retain efficiency over time. The high-HSPF heating captures heat from outside air.
Water circulates through a verticle loop of piping in the earth or a horizontal loop and grid in a pond to exchange heat where temperatures are more stable.
Geothermal heat pumps have no outside compressor unit – only piping underground -- so there's no need to hide or protect equipment from flooding, wind or impact damage.
In the dual-fuel heat pump system, a 90% AFUE direct vent furnace is installed instead of an inefficient electric strip heating element for efficient backup heating in cold weather (cost-effective in north La.).
LaHouse includes 3 heating, ventilation and air conditioning (HVAC) systems.
