Change the filter
A clean filter protects the equipment and keeps air fresher. Check it monthly and replace it as often as the label suggests.
Use the thermostat well
A programmable or smart thermostat saves energy by matching temperature to your day. Small changes held steady work better than big swings.
Listen and look
Strange noises, ice on the outdoor unit, uneven rooms and musty smells all say the system wants attention.
Service and replacement
Annual tune-ups catch small problems early. When a system is old and repairs add up, a pro can compare repair and replacement and explain sizing and efficiency.
