Heat pumps cause noise, and in urban areas this can lead to complaints from the neighbors. Disturbing noise can affect human health adversely by causing sleep disturbances and difficulties to concentrate. Miljöbalken states that the one who installs a heat pump on his or her land is responsible for the noise that it generates. Naturvårdsverket has issued benchmarks that will serve as guidelines for noise measurements, when a suspicion of risks for human health is. Municipalities may also adopt limits in local regulations. Noise measurements are often done on the property line but a judgment of a precedent case from 2012 concludes that the measurements should be done at the facade and patio.  A survey was mailed to 221 companies that installed heat pumps. The responses showed a divided opinion on the question of how frequently the companies felt that the problems of noise complaints occurred. Most companies often discussed noise reduction measures with their customers in connection to the installation of the heat pump. However, it was far from all, though many, who used the existing regulations and guidelines in their counseling with the customers. Few companies used the benchmarks from Naturvårdsverket. The indistinct way to apply Naturvårdsverkets benchmarks that is shown in the summed cases in this report can make it difficult for the companies to use these in consultation with their customers.
