As the warm Philadelphia summer approaches, ensuring your HVAC system is in top shape is crucial for maintaining comfort and efficiency. Here's your comprehensive guide to preparing your HVAC system for the upcoming heat, keeping your home cool and your energy bills low.

1. Change Your Air Filters

One of the simplest yet most effective steps you can take is to replace your HVAC air filters. This not only improves air quality by removing dust, pollen, and other allergens but also enhances your system's efficiency. In Philadelphia's urban environment, where air quality can be a concern, regular filter changes are essential. Aim to replace your filters every 90 days, or more frequently if you have pets or allergies.

2. Clear Around Outdoor Units

Ensure your outdoor HVAC units have clear space around them. Remove any debris, leaves, or branches that could obstruct airflow. A good rule of thumb is to maintain at least a 2-foot clearance around the unit. This simple maintenance task can significantly impact the system's efficiency and prevent overheating during the hottest days.

3. Schedule a Professional Inspection

Before the peak of summer hits, it's wise to have a professional HVAC technician inspect your system. A thorough inspection can identify any potential issues that could lead to breakdowns during summer when you need your system the most.

4. Check Your Thermostat Settings

Optimizing your thermostat settings can lead to substantial energy savings. Consider setting your thermostat to a comfortable yet energy-efficient temperature. When you're away, adjusting the temperature by 7-10 degrees can save you up to 10% a year on cooling costs. Also, consider upgrading to a smart thermostat for even greater control and savings.


Preparing your HVAC system for summer in Philadelphia not only ensures comfort but also contributes to energy savings. By following these simple steps—changing air filters, clearing outdoor units, scheduling a professional inspection, and optimizing thermostat settings—you can enjoy a cool, comfortable home all summer long.
