Your home air conditioning system’s evaporator coils should be cleaned at least once a year. If your air conditioner’s evaporator coils are dirty, it can cause your air conditioning system to run less efficiently and can cost you 30 percent more on energy. Fortunately, if your air conditioner is on a maintenance plan, your HVAC technician will typically clean your evaporator coils as part of your air conditioner’s regular maintenance.
