After upgrading your HVAC system, taking proactive steps to maintain it can significantly extend its lifespan, ensuring it runs efficiently and effectively for years to come. Here are some essential maintenance tips for Philadelphia homeowners to maximize the longevity of their HVAC systems.

Regular Filter Changes

  • Frequency: Change your air filters every 30 to 90 days, depending on usage and the type of filter. Homes with pets or high dust levels may require more frequent changes.
  • Benefits: Regular filter changes ensure better air flow and efficiency, reducing strain on the system and preventing dust and allergens from circulating through your home.

Annual Professional Servicing

  • Importance: Have a professional HVAC technician service your system at least once a year. This should ideally happen in the spring for air conditioning systems and in the fall for heating systems.
  • Services Included: This typically includes checking and cleaning the condenser and evaporator coils, checking the refrigerant levels, and ensuring all electrical components are functioning properly.

Clearing the Area Around Outdoor Units

  • Space Requirements: Keep at least 2 feet of clearance around your outdoor HVAC units. Remove any debris, leaves, or overgrowth that could obstruct airflow.
  • Benefits: This prevents overheating and helps maintain optimal performance.

Checking and Sealing Ductwork

  • Inspection: Inspect your ductwork annually for leaks or damage, especially if you notice an unexpected increase in your utility bills or areas of your home that seem harder to heat or cool.
  • Action: Use duct sealant or metal-backed tape to seal any leaks. Consider hiring a professional if extensive repairs are needed.

Monitoring Thermostat Settings

  • Optimal Settings: Keep your thermostat at a consistent temperature as much as possible. Constant adjustments can cause unnecessary strain on your HVAC system.
  • Energy Savings: Consider installing a programmable thermostat that adjusts the temperature based on your daily schedule, enhancing comfort and reducing wear and tear.

Upgrading Insulation

  • Home Efficiency: Check and upgrade insulation in your attic and walls to improve your home’s overall energy efficiency. Good insulation reduces the workload on your HVAC system by maintaining a more stable indoor temperature.


Maintaining your HVAC system doesn’t just prolong its life; it also enhances its efficiency and effectiveness, saving you money on energy bills and costly repairs. For Philadelphia homeowners, where weather can fluctuate widely, regular maintenance is especially crucial. Whether you handle some tasks yourself or rely on professionals like McCorry Comfort for more technical maintenance, the goal is to keep your system running smoothly for as long as possible. By following these tips, you can enjoy a comfortable home environment throughout all seasons.
