Caring for your window AC unit is essential for ensuring it operates efficiently and extends its lifespan. Without regular attention, your air conditioner may struggle to cool your space, consume more energy, and potentially lead to costly repairs. Proper upkeep helps you avoid these issues while keeping your home comfortable during the warmer months.
In this guide, we’ll discuss the best ways to maintain your window AC unit, including simple tasks you can do yourself and when it’s time to call an HVAC contractor for professional assistance.
1. Clean or Replace the Air Filter Regularly
One of the most important maintenance tasks for a window AC unit is cleaning or replacing the air filter. A clogged or dirty filter restricts airflow, reducing the unit’s cooling efficiency and forcing it to work harder. This not only increases your energy bills but can also lead to more significant issues down the line.
- How often to clean/replace: During peak usage in the summer, clean or replace the filter every 30 days. Some filters are reusable and can be washed with water, while others need to be replaced. Check your unit’s manual to see which type of filter your air conditioner uses.
- Signs of a dirty filter: Reduced airflow, longer cooling times, and visible dust buildup are signs that it’s time to check your filter.
2. Inspect and Clean the Coils
Your window AC unit’s evaporator and condenser coils play a critical role in the cooling process. Over time, these coils can accumulate dirt and dust, reducing their ability to absorb heat and decreasing the unit’s overall efficiency.
- How to clean the coils: First, turn off the unit and remove the front panel. Use a soft brush or vacuum cleaner to gently clean the coils. Be careful not to bend or damage the fins. For heavy buildup, a coil cleaner spray designed for air conditioners may be helpful.
- When to clean: Aim to clean the coils at least once a year, preferably before the summer season begins.
3. Ensure Proper Sealing Around the Window AC Unit
A common issue with window AC units is poor sealing around the unit. Gaps between the window frame and the AC can allow warm air to leak in, forcing your air conditioner to work harder to cool the space.
- Check for leaks: Regularly inspect the area around your window AC unit for any gaps or drafts. You can use weatherstripping or caulk to seal these openings and improve the unit’s efficiency.
- Why it matters: Proper sealing helps maintain a consistent indoor temperature and reduces energy waste, ensuring your unit runs as efficiently as possible.
4. Clean the Unit’s Exterior and Interior
Dirt, dust, and debris can accumulate on both the inside and outside of your window AC unit. Keeping both areas clean ensures optimal performance and longevity.
- Exterior cleaning: Use a damp cloth to wipe down the exterior of the unit. Make sure there’s no dirt, leaves, or debris blocking the vents.
- Interior cleaning: If you’re comfortable doing so, you can remove the unit from the window and give it a more thorough cleaning. Be sure to turn off the power and take precautions to avoid damaging any internal components.
5. Straighten Bent Fins
The fins on your window AC unit’s evaporator and condenser coils help move air through the system efficiently. Over time, these fins can become bent, reducing airflow and making the unit less efficient.
- How to fix bent fins: You can use a fin comb, a small tool designed to straighten AC fins. Carefully run the comb over the fins to straighten them out.
- When to do this: Inspect the fins when cleaning the coils or if you notice reduced airflow from the unit.
6. Check the Thermostat and Control Settings
Your window AC unit’s thermostat ensures the room reaches your desired temperature. If the thermostat is faulty or miscalibrated, your air conditioner may run longer than necessary or fail to cool the room effectively.
- Test the thermostat: Set your thermostat to a specific temperature and observe whether the unit shuts off once that temperature is reached. If the unit keeps running or doesn’t reach the desired temperature, it may be time to call an HVAC contractor to inspect the thermostat.
- Control settings: Ensure that your unit’s settings (such as fan speed and cooling mode) are appropriate for the current weather conditions. This can help optimize energy use and comfort.
7. Store Your Window AC Unit Properly During Off-Seasons
If you live in an area with cold winters, it’s a good idea to remove and store your window AC unit during the colder months. Leaving it in place can expose it to harsh weather conditions that may damage the unit over time.
- How to store it: Remove the unit carefully from the window, clean it thoroughly, and store it in a dry, cool place. Cover it with a protective sheet or use the original packaging to keep it safe from dust and debris.
- Why it’s important: Proper storage helps prolong the life of your window AC unit and ensures it’s ready to go when summer rolls around.
8. Schedule Professional Maintenance
While regular DIY maintenance can go a long way in keeping your window AC unit in top shape, there are times when professional help is necessary. A licensed HVAC contractor can perform a more thorough inspection, check for refrigerant leaks, and ensure all components are functioning properly.
- When to call a professional: If your air conditioner isn’t cooling efficiently, makes unusual noises, or you notice any leaks, it’s best to schedule a professional maintenance check.
- Benefits of professional maintenance: An HVAC contractor can catch issues early before they become major problems, saving you money on repairs and extending the life of your unit.
