Are you concerned that your central air conditioning system isn’t working as well as it could be? If your utility bills are high or if you need to run your AC for long hours to keep your Seattle home at a comfortable temperature, there are some steps you can take to make your system more efficient. You might begin by buying a programmable thermostat, which keeps your bills lower by ensuring that you aren’t cooling your home when you’re asleep or when nobody is home. You should also change out your air filters regularly—at least once a month during periods of heavy AC use. Don’t forget to have your system serviced from time to time by an HVAC professional.
