Choosing the Right Heat Pump
There are several factors to consider before buying a heat pump. Here are some things to take into account.
Initial Costs Versus Operating Costs
The biggest expense over the life of a heat pump (or any heating and cooling system) is not the cost of buying and installing it. It's the accumulated monthly cost of running it year after year. Usually, as the efficiency rating of a unit goes up, so does the initial cost. However, as the efficiency rating goes up, the monthly cost to operate the unit goes down. You'll want to consider the importance of a high-efficiency system and the trade-off between your initial cost and the monthly operating costs. If you’re planning on living in the same house five years or more, consider installing a more efficient system.
Size
To work most efficiently, a heat pump's heating and cooling capacity has to match your home's heating and cooling demands. An undersized system won't adequately cool your home, while an oversized one won't dehumidify properly and can make the house feel drafty in the winter. A member of the Quality Contractor Network (QCN) can best tell you what you'll need. These heat pump contractors have all met the high standards set by your local power company and TVA for participating in their heat pump program.
Duct System
This is very important because the heat pump will pump air all through your house using this system. The ductwork must be insulated and sealed properly so the air gets where it's going at the right temperature. Proper construction of the ductwork is essential to ensure efficient operation of the heat pump over the life of the system. Care taken in the initial construction and sealing of the ductwork will yield maximum efficiency from the heat pump for years to come. Again, a member of the QCN can best tell you whether you'll be able to use your existing ductwork or will need new ducts.
