Replacing a heat pump in 2026: cost and how to skip it

If your current heat pump has started making strange noises, is drawing more electricity than usual, or has simply reached the end of its life (often after 10–15 years), you're not alone. But in a time of economic uncertainty, an investment of SEK 100,000–200,000 isn't always appealing.

Most homeowners start reviewing their heating when they notice the electricity bill rising even though their usage pattern is the same. An old heat pump loses efficiency, which means it has to use more electricity to produce the same amount of heat.

There are a few clear signs that it's time for a replacement. The pump is older than ten years. The compressor is unusually loud or stutters. You've had a technician out more than once in the past two years. And modern pumps are considerably more efficient than the ones sold ten years ago, and they run more quietly too.

The cost of a traditional heat pump replacement varies depending on which technology you choose. Here are the estimated market prices for a turnkey job (hardware plus installation), after the ROT deduction: an air-to-air heat pump costs roughly SEK 20,000 to 35,000, an air-to-water heat pump SEK 130,000 to 190,000, and a ground-source replacement SEK 110,000 to 150,000. The prices include installation but assume that existing boreholes or pipe systems can be reused.

The most common reason homeowners hold off on replacing their heat pump isn't a lack of will. It's the invoice. An investment of SEK 100,000 to 200,000 is hard to justify, and a new loan feels risky when interest rates are what they are.

The problem is that waiting costs money. An old, inefficient pump keeps drawing more electricity than it needs, every day, every winter. The difference can easily add up to thousands of kronor a year.
