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 its most efficiency.
I have closed doors to seal off the 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 unit 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 Pumps - 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 the 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.
HVAC Tip - According to studies done by the Department of Energy, 50 percent of the heat loss experienced in the average home occurs through the ceiling. That makes a lot of sense since heat rises. You can reduce that heat loss (heat gain in the summer months) by adding another layer of insulation in the attic. That will hold more heat in our homes for a longer period of time which means the furnace will cycle less. That means you are going to save money. A lot more money than another layer of insulation costs. Additionally, having an attic fan controlled by a thermostat installed in your attic will remove a lot of heat in the summer. This will help you, in addition to having more insulation, reduce heat gain from the attic in the summer.
