Keeping your home air conditioning (AC) system in tip-top shape doesn’t have to be a chore. Here’s a straightforward, step-by-step guide to performing a DIY AC maintenance tune-up.
1. Safety first! Start by turning off the power to your AC unit at both the outside compressor and the breaker box to avoid any electric shock risks.
2. Locate the fan cage on the outdoor compressor and remove it. Clear away any visible debris by hand or with a vacuum cleaner.
3. Using a vacuum with a brush attachment, give the fins a good cleaning. Rinse off any stubborn dirt with a gentle spray from a garden hose. Avoid using a pressure washer, as it can cause damage.
4. If any fins are bent, they can restrict air flow and lessen your AC’s efficiency. Carefully straighten them using a butter knife or a fin-straightening tool, taking care not to damage the internal tubing.
5. Once the cleaning is done, replace the fan cage and ensure that the area around the unit is clear of debris and vegetation for at least two feet.
6. Over time, the condenser’s pad can become unbalanced, which may lead to premature breakdowns. Check and adjust your condenser’s level as needed.
7. Inside your home, locate the evaporator coil door on your furnace unit. Open it, clean the coil with a soft brush, then spray on a no-rinse coil cleaner. Finish up by cleaning the drain pan with soap, hot water, and a bit of bleach.
8. Clear the evaporator drain thoroughly to prevent mold and algae accumulation, which can lead to severe water damage.
9. For optimal performance, replace your blower filter at least twice a year.
10. Once all tasks are complete, it’s safe to turn the power back on.
Remember, while these steps are helpful for maintaining your AC, hiring a professional HVAC technician for a comprehensive maintenance check is sometimes the best option.
