The savings from an AC tune-up can be quite significant. By ensuring that all components are functioning correctly, the system uses less energy to produce the same cooling effect. For instance, a clogged air filter can strain the air conditioner, leading to higher energy use. Regularly replacing or cleaning the air filters can lower your air conditioner’s energy consumption by 5% to 15%. Additionally, ensuring that the evaporator and condenser coils are clean and that the refrigerant level is optimal can improve efficiency and further reduce energy costs. On average, homeowners might see a reduction of up to 20% in their cooling costs with regular AC maintenance.
