Full System AC Maintenance: During a thorough AC maintenance service, I inspected and cleaned the coils, replaced the air filter, tightened electrical connections, cleaned the blower fan, and assessed refrigerant levels. I also calibrated the thermostat, cleared the condensate drain, and performed system tests to ensure the AC system was working efficiently and reliably. This service maintains the equipment's lifespan, boosts energy efficiency, and keeps the indoor environment comfortable.
