Fortunately, the letter that you received indicated that the initial test for HIV antibodies was a false positive. This means that the test wrongly showed that your blood was infected with HIV, when in fact, it was not.
A heat pump will replace both the furnace and air conditioner/central air unit. It may be costly to install, with the national average falling between $3,956 and $6,702, but it will save you considerable money in energy costs.Consider the following factors before installing a heat pump:The biggest single factor is determining the price of your heat pump is the size of your house.he cost of installing a heat pump will be more expensive for the geothermal type than air-source as it needs to be installed underground. The difficultly associated with the excavation of the ground will affect the installation costs.
Using these prices, a heat pump with a COP of 3.5 in moderate climate would cost $0.97 to provide one therm of heat, while a high efficiency gas furnace with 95% efficiency would cost $1.22 to provide one therm of heat. With these average prices, the heat pump costs 20% less to provide the same amount of heat.igher COPs equate to lower operating costs. The COP may exceed 1, because, instead of just converting electricity to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to where the heat is required.
