Annual maintenance for your air conditioner is recommended. However, there are also DIY AC maintenance tasks that can increase system performance, efficiency, and longevity. We’ll look at simple things you can do between cooling services to prevent damage to your air conditioner and save money.
- Change or Clean the Filter
- Check the Thermostat
- Inspect Your AC System’s Wiring
- Inspect the Condenser
- Check for Air Leakage Around Your Home
- Clean the Vents and Registers
- Look for Leaks
- Clean the Evaporator Coil and Drain
- Shade the Outdoor Compressor in Summer
1. Change or Clean the Filter
Air conditioner filters should be checked once a month and changed every 1 to 3 months. Don’t wait for AC maintenance by your HVAC contractor. The filter is easy to replace; this avoids airflow restrictions that can overwork the system. Some filters are reusable. If you have a reusable AC filter, clean and reinstall it periodically so the system works efficiently.
2. Check the Thermostat
Checking the thermostat settings helps ensure your AC is prompted to run when it’s needed. If your home is warmer than it should be, see if the thermostat is set to “Cool” mode. Also, note your comfort level. If possible, turn the thermostat up a few degrees and adjust it higher when you’re away to reduce energy consumption. You can also run a ceiling fan to increase the cooling effect.
3. Inspect Your AC System’s Wiring
Air conditioning systems have many wiring connections. While you shouldn’t attempt to remove or repair any electrical wires yourself, it’s a good idea to check them. Check the power and cutoff switches for any signs of damage. If any accessible electrical components or the unit exterior are dirty, brush or hose off any debris (after turning the power off).
*Don’t open the system to clean the interior or adjust any wires or electrical components yourself. Your AC contractor will do this during an annual AC tune-up.
4. Inspect the Condenser
Being exposed to the elements, the outdoor condenser unit is susceptible to wear and tear. Check it regularly for damaged fan blades, burnt wires, or signs of overheating. An older model may require oiling the fan periodically. It’s also a good idea to trim shrubbery away from the unit. Leave at least two feet of clearance on all sides.
5. Check for Air Leakage Around Your Home
Issues with air leakage can cause conditioned air to escape your home or warm air to enter. Your AC system will work harder to keep things cool, strain itself, and use more energy. To address and prevent such issues, check for proper sealing around windows and doors. Install caulk or weatherstripping if necessary. Also, inspect your ductwork where possible for signs of holes or loose connections that can allow air to leak. You may need a professional for duct sealing or repair.
6. Clean the Vents and Registers
If vents and registers are covered in dust, dirt, and debris, the system will run less efficiently and struggle to cool your home. To clean them, brush from top to bottom and left to right. If any debris is left over, remove it with a vacuum cleaner. Look for signs of a deeper problem in your ducts, such as a blockage or mold, and call a professional for a more thorough duct cleaning if necessary.
7. Look for Leaks
Signs of leaks include musty smells, visible mold, or reduced indoor air quality. Whether you suspect a problem or haven’t checked the system recently, inspect the condenser unit, fan, air vents, air handler, and evaporator coil for signs of leakage. A leak can quickly lead to costly water damage. If the temperature is fluctuating or the system is noisy, there may be a refrigerant leak, which can harm your HVAC system and health. Call a professional to address any type of leak.
8. Clean the Evaporator Coil and Drain
Even when not using your air conditioner, check and clean the evaporator coil and drain regularly. If the coil becomes coated in dust, dirt, or mineral deposits, your AC won’t work as efficiently. Fortunately, you can clean the coil and drain with a vacuum cleaner and the appropriate attachments (a wand or hose attachment is best).
9. Shade the Outdoor Compressor in Summer
Shading the compressor shields it from hot temperatures that can cause damage. Direct sunlight can otherwise cause it to overheat; it can also cause the refrigerant to evaporate too soon. Therefore, adding some shade can prevent the compressor from breaking down.
