The old adage is true: an ounce of prevention is worth a pound of cure. That’s why we encourage all AIR CONDITIONER owners to perform preventative maintenance. Below you’ll find our Preventative Maintenance Checklist, which is our proven method to keep your system in the pink and your home in constant comfort.

When to schedule maintenance:  If your system heats and cools your home:     Perform maintenance in the spring and fall  Cooling-only:     Perform maintenance at least once a year, before the cooling season.  Heating-only:     Perform maintenance at least once a year, before the heating season.  Outdoor Units You should expect your service technician to:   Inspect unit for proper refrigerant level and adjust if necessary   Clean dirt, leaves and debris from inside cabinet  Inspect base pan for restricted drain openings—remove obstructions as necessary  Inspect coil and cabinet—clean as needed  Inspect fan motor and fan blades for wear and damage—on older models lubricate as needed  Inspect control box, associated controls/accessories, wiring and connections. Controls may include contactors, relays, circuit boards, capacitors, sump heat and other accessories. All control box and electrical parts should be checked for wear or damage   Inspect compressor and associated tubing for damage  Indoor  Units   Inspect and clean blower assembly (includes blower housing, blower wheel and motor)   On older models, lubricate motor and inspect and replace fan belt if needed  Check combustion blower housing for lint and debris and clean as necessary  Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed  Inspect for gas leaks in gas furnaces  Inspect burner assembly—clean and adjust as needed   Inspect ignition system and safety controls—clean and adjust as needed   Inspect heat exchanger or heating elements   Inspect flue system - check for proper attachment to the furnace, any dislocated sections, and for signs of corrosion. Replace if necessary   Inspect control box, associated controls, wiring and connections   Clean or replace air filters   Inspect conditioned airflow system (ductwork)—check for leaks   While your system is operating   Monitor system starting characteristics and capabilities   Listen for abnormal noise  Search for source of unusual odors  Monitor air conditioning and heat pump systems for correct refrigerant charge  Measure outdoor dry bulb temperature  Measure indoor dry and wet bulb temperature   Measure high and low side system pressures   Monitor gas furnace for correct line and manifold gas pressure - make adjustments as needed   Measure temperature rise and adjust airflow as needed   Check vent system for proper operation   Monitor system for correct line and load volts/amps   Monitor system operation per manufacturer's specifications   Provide system operation report and recommend repairs or replacement as necessary NOTE: We recommend all maintenance and service work be performed by a professional air conditioning and heating dealer that holds the appropriate credentials to install and service air conditioning and heating equipment.
