Benefits of Cleaning Your Air Conditioner
Learning how to clean an outside air conditioner as well as your indoor system comes with a number of important benefits.
Better Air Quality
Get rid of the dust, dirt, and other debris clogging your HVAC system and you’ll prevent all that buildup from coming out of your vents. That means better air quality and fewer irritants to annoy your lungs or cause colds and asthma to flare up.
Improved Performance
Clean systems simply work better. Paying special attention to cleaning and realigning every component can reduce friction and allow your AC to cool easily, without working against dirt or other issues.
Reduced Energy Costs
When your AC works more efficiently, it cools faster. Using less energy to achieve the same result is less taxing on the environment, and it can lower your energy bills, too.
Extended AC Lifespan
As regular cleanings reduce the workload for your AC unit, they also help extend your system’s lifespan. Air conditioners that work smarter, not harder, typically last longer and need repairs less frequently.
Gather the Necessary Tools and Materials
Before you tackle a DIY air-conditioner cleaning, you need to gather all the necessary supplies. This will help you complete the task sooner and avoid getting caught without an essential tool.
You may need:
- A vacuum
- Gloves
- New filters
- A screwdriver
- A soft-bristled brush
- A water hose with a sprayer attachment
- Eye protection
- Cleaning solutions (only use products recommended and/or approved by the AC manufacturer)
How to Clean a Lennox Air Conditioner
Here’s how you can clean your Lennox AC and other similar units.
Step 1: Unplug Unit or Turn Off Breaker
Start by cutting off the power to your unit. This ensures you can work safely.
Step 2: Clean or Replace Filter
Dirty filters can reduce your AC unit’s efficiency. Gently scrub permanent filters with a soft-bristled brush and approved cleaner, spray to rinse, and allow them to dry. Indoor filters should be replaced about once a month.
Step 3: Clean Fins and Coils
Next, clean the dirt off your evaporator and condenser coils. Follow the same procedure as the filters above, but realize you may need to let the cleaner sit in order to remove buildup.
Step 4: Clean Condensation Drain and Pan
Consult your user manual to find the drain pain. Empty the pan using a wet/dry vac, then flush vinegar into the drain line to finish the cleanout.
Step 5: Reassemble Unit
Finally, reassemble your unit, turn the power back on, and test the system to ensure everything is running smoothly.
