Philadelphia weather can get hot and humid, so having an air conditioner that runs efficiently and effectively is key to staying comfortable through the summer. While most well-maintained AC units need very little work to get ready for the summer, it’s still a good idea to check these five components and make sure your AC is running at its best.


The first step for AC maintenance is to go outdoors and take a look at your compressor. A lot of debris can accumulate here during the fall, winter, and early spring. This can be anything from fallen leaves shrouding the vents to tall weeds or shrubs growing along the sides. It’s important to remove all of this buildup; otherwise, your air conditioning system may not be able to expel hot air through the vents.

You may also want to rinse the entire unit with a garden hose and plain water to remove dirt and dust.


It’s also a good idea to check for any signs of low refrigerant levels, worn parts, or other issues. If you spot something suspicious, contact a professional technician for an inspection or repair service.

While you’re at it, use a diluted bleach system to clean the condensate drain line and drain pan, which can develop mold and mildew and lead to a clogged drain. Take a look at your air filter as well to make sure it’s clear and clean. Remember to replace the filter every month to maintain your cooling system’s performance and improve your indoor air quality.


The inside of your home may also need some attention. Check all of your vents to make sure they’re not closed or blocked by carpets and furniture. It’s also a good idea to perform an annual inspection of your ducts to check for mold growth, blockages, or leaks. Alternatively, you can opt for a professional service, where an experienced technician will utilize state-of-the-art AC air duct cleaning machines for fast, efficient, and thorough cleaning.


If you want to make sure your air conditioner is ready for Philadelphia’s summer weather, consider having a professional inspection and tune-up. AC technicians have the experience and training to recognize potential problems before they occur, which can help ensure your air conditioner keeps humming along even on the hottest days. They can handle everything from filter replacements to new system installations.
