The Ultimate DIY Tips for Air Conditioning Maintenance

Keeping our homes at comfortable temperatures is vital, especially in intense weather conditions. With years of experience, R.H. Witt provides full services of Air Conditioning Installation and Repair. However, did you know that you can handle some basic maintenance for your air conditioning system yourself? Here are the indispensable tips for DIY air conditioning maintenance.

Regular Filter Checks

The easiest and most essential step in air conditioning maintenance is to regularly inspect and replace the filter. A blocked filter can obstruct airflow, causing your system to lose efficiency and might even impair the evaporator coil’s capacity to absorb heat. A quick filter change can lower your AC’s energy investments by 5% to 15%.

Coil Cleaning

Your air conditioner’s evaporator and condenser coils collect dirt over time, and this accumulation can reduce airflow. It’s a good idea to check your coils every year and clean them. Remember to trim foliage back at least 2 feet around your outdoor units to promote adequate airflow around the condenser.

Unclog The Drain

The drain channel should be clear of potential clogs which could obstruct the pathway, leading to high humidity levels in your home. You can use a stiff wire to pass through the drain channels and clear any potential clogs. This is a small act that can significantly reduce the chances of costly future repairs.

Inspect Sealants & Window Seals

If you own a room air conditioner, inspect the seal between the air conditioner and the window frame. Make sure it makes contact with the unit’s metal case. Over time, moisture can damage these seals, letting in cool air and impairing your unit’s efficiency.

Professional Inspection

While DIY checks and procedures prove extremely beneficial, a professional inspection at least once a year ensures your system is running optimally. The experts can fix any more severe issues before they get a chance to worsen. This is where R.H. Witt can help.

Although there are simple steps homeowners can take to maintain their AC units, ensuring optimal functionality often requires professional assistance. There’s no better time than now to invest in a regular maintenance plan with a reputable company like R.H. Witt.


Performing your own air conditioning maintenance not only keeps your unit running efficiently and extends its lifespan, but also saves you money in the long run. However, always consult a professional when needed. R.H. Witt is equipped to offer professional help, including air conditioning installation and repair, ensuring a comfortable climate in your home all year round.
