Beyond the type of heat pump and its size, here are other factors that influence the price of heat pump installation.
Like other home appliances, heat pumps vary in price depending on their brand. Recognizable brands such as Trane and American Standard are typically more expensive, but their products are often higher in quality and perform better in large spaces. High-efficiency models are also more costly than standard ones. We recommend discussing which brand you should purchase with an HVAC professional, as you may need a specific brand to match your other HVAC system components.
An HVAC technician may have to install extra ductwork or repair your existing ducts depending on your new heat pump. Duct replacement costs an extra $500 to $2,000. However, if you only need a small section of ductwork repaired or replaced, you may only pay $10–$20 per linear foot plus labor costs.
Each HVAC manufacturer discloses efficiency ratings to help homeowners choose the most efficient and sustainable HVAC solution for their home. Heat pumps have two efficiency ratings. One is its Seasonal Energy Efficiency Ratio (SEER), which denotes how efficiently a heat pump cools a home. Typical SEER ratings fall between 14 and 24, with the higher number being the most efficient.
The heat pump’s Heating Seasonal Performance Ratio (HSPF) is the other energy efficiency rating. This rating is similar to SEER, but it measures the heat pump’s efficiency for heating instead of cooling. HSPF ratings range between 8.2 and 13, with the higher number being the most efficient.
Labor costs vary depending on the heat pump type. For example, geothermal units take more work to install because they require more expertise and must be buried at least 4 feet into the ground. Ductless mini-split heat pumps can cost as little as $500 to install, as the process is simple and quick.
Most heat pump installations require a permit. You may even need multiple permits, depending on if you need to dig on your property or live near other city amenities. Most cities and counties require a mechanical or building permit to install, alter, replace, or repair any heating pump, air conditioner, or duct system. Check with your local government to determine which permits or fees are required. Permit costs depend on your location and other local ordinances, but you can anticipate spending between $50 and $300.
