Closing Off Part of the House To Save Energy on HVAC – I have a Heil gas/electric package unit in my home. I, particularly, want to know, if I can close off a section to save on heating. Heating dealers have not been helpful as they hedge on whether and how this can be done with the system still running at it’s most efficient. I have closed doors to seal off area. Then closed floor registers. Should I also close air return in that area? I just read this should not be done at all as it decreases units efficiency? Will you please advise. I am thinking of closing off part of the house to save energy on HVAC. Thank you. (more…)

Air Source Versus Geothermal Heat Pump Heating Systems . A heat pump is an electric cooling and heating system. It is used to compress and decompress gas to heat or cool a house. This mechanical device pumps heat from a cooler to a warmer location. It can extract heat from air, water or the earth. Heat pumps function like an air conditioner in the summer and an electric furnace in the winter. Therefore, encompassing both a heating and a cooling unit in one device. The COP, or coefficient of performance, calculates the ratio of heat output to electric power consumption. Therefore, COP& measures the performance of a heat pump. (more…)
Dual Two-Stage Split System with a Dual Slab Coil. Huh?
Richard - Very nice site!- Dual Two-Stage Split System with a Dual Slab Coil - I have a question; my home was fitted out by the previous owner with a twinned system, and a thermostat (Totaline P374-1900) which was not designed to control discreet, paired units. I confirmed this with Totaline. The result is only one unit runs, and the second unit is never activated. It functions, but not automatically.
