Our Licensed Technicians & Local Plumbers in Wayne, PA Will Help You Find a New Heat Pump Why It’s Important to Choose a Proper Heat Pump Size However, energy-star rated systems can save you money on your utility bill in the long run. With higher SEER ratings comes a higher system cost. HSPF measures the efficiency of air-source heat pumps. On the other hand, energy-star rated heat pumps feature SEER ratings that vary from 18 to 27.5.įor warmer climates, we recommend getting a device with a higher SEER for colder climates, look for a higher HSPF rating. For heat pumps, you should consider a model with a 15 SEER rating or higher. The higher the SEER rating, the more efficiently your heat pump system can produce warm and cold air. For the remainder of the country, the minimum standard is 14. This then is divided by the energy it uses into Watt-Hours.įor Northeast, Midwest, and Pacific Northwest, 13 SEER is the federal minimum standard for new units. A SEER rating is a ratio that measures the cooling efficiency for air-source and ductless-split systems. The acronym SEER stands for Seasonal Energy Efficiency Ratio. When you are sizing a heat pump system for your household, make sure to invest in a device with a good SEER rating. Because of this, electric resistance heating is less efficient than your heat pump and should only be used when needed. If you live in an extremely cold climate, typically below 10 degrees fahrenheit to 25 degrees fahrenheit, you may need to get an auxiliary heating system.Īuxiliary heat utilizes electric resistance heating to convert nearly 100% of energy in the electricity to heat. That’s why you must do your research to ensure you get the right heat pump or heating system for your home.

Once an HVAC professional has completed a Manual J Inspection, you are then ready to choose the heat pump size that’s right for your home. Variables such as insulation levels, the size of your home, and air duct tightness are evaluated to determine how much heating and cooling you need. Manual J is a protocol, devised by the ACCA (Air Conditioning Contractors of America Association), that acquires instructions for assessing your home’s structural and thermal characteristics. Prior to determining what size heat pump you need, you must first hire an HVAC technician to perform a Manual J inspection. Need Help?

However, any changes to the home may require a different size heat pump. If your old heat pump system was sized correctly, an HVAC professional can easily replace your heat pump with a similar model. To properly evaluate the number of BTUs needed, we recommend speaking with an HVAC professional. Based on space, size, insulation, and many other variables of the home, you can determine the number of BTUs you’ll need. You do this by calculating in cubic meters the total volume of spaces being heated. The first step to sizing a heat pump is to conduct a load calculation.
