How the Size of your Heat Pump Affects Home Comfort and Energy Efficiency Long-Term

A heat pump is an excellent comfort-system investment for the northern Virginia homeowner who wants to capitalize on the system’s cooling and dehumidification efficiency during hot and humid summer days, while gaining energy-efficient heating during the winter. If you’re getting a new heat pump, keep in mind that the size of your system will greatly affect home comfort and long-term energy efficiency. Size it correctly, and it will deliver.

How a heat pump cools and dehumidifies

A heat pump doesn’t make cold air. Instead, it makes the air colder. The system does this by using the natural properties of refrigerant to extract heat from the warm air inside your home. As warm air is pulled over the cooling coil (evaporator), heat from the warm air is absorbed by the refrigerant, the same way ice absorbs heat and makes the surrounding air cooler.

The size of your heat pump

Although a heat pump is a highly efficient cooling and heating system, it is only as good as its installation. And a quality installation begins with an accurate load calculation that can determine the size that’s appropriate for your home. Your expert HVAC-system professional will use Manual J, the gold standard, to assess various factors in your home, such as square footage, insulation levels, the number of people in your home and the number of windows. Then he’ll use Manual D to determine the duct layout. Finally, he’ll use Manual S to ensure that the size of your new system is correct.

These calculations will yield a system that is neither too big nor too small.

You can help to reduce your initial outlay by increasing your home’s energy efficiency before you have that new system installed. Air sealing and boosting your insulation are too key ways you can make your home tighter before that new heat pump goes in.

You’re putting out good money for that new heat pump. Make sure it’s sized correctly and installed by experts who are skilled and experienced. Contact the professionals at HVAC & Plumbing Unlimited. We serve Lorton-area homeowners.
