A Seasonal Guide to HVAC Maintenance: What to Do and When

Proper HVAC maintenance is crucial for ensuring your heating and cooling systems run efficiently and reliably year-round. Neglecting maintenance can lead to reduced performance, higher energy bills, and costly repairs. At ASM HVAC NYC, we understand the importance of regular maintenance and are here to help you keep your system in top shape. This seasonal guide will provide detailed HVAC maintenance tips for homeowners and businesses, helping you prepare your system for different times of the year.

Spring: Prepare for the Cooling Season

Spring is the ideal time to prepare your HVAC system for the upcoming cooling season. As temperatures start to rise, ensuring your air conditioning unit is ready to handle the heat is essential.

1. Schedule a Professional Inspection:
   • Before the hot weather hits, schedule a professional HVAC inspection. A technician will check for any issues and perform necessary maintenance to ensure your system is ready for summer.
2. Replace Air Filters:
   • Clean or replace air filters to ensure proper airflow and improve indoor air quality. Dirty filters can restrict airflow, making your system work harder and less efficiently.
3. Clean the Outdoor Unit:
   • Clear any debris, such as leaves and dirt, from around the outdoor unit. Ensure at least two feet of clearance around the unit for optimal performance.
4. Check Thermostat Settings:
   • Adjust your thermostat settings for the cooling season. Consider upgrading to a programmable thermostat to save energy and improve comfort.
5. Inspect Ductwork:
   • Check for any visible leaks or damage in your ductwork. Sealing leaks can improve efficiency and reduce energy bills.
6. Clean Coils:
   • Clean the evaporator and condenser coils to remove dirt and debris. Clean coils can improve efficiency and extend the life of your system.

Summer: Maximize Cooling Efficiency

During the summer, your HVAC system works hardest to keep your home or business cool. Regular maintenance during this season is essential to maintain efficiency and prevent breakdowns.

1. Monitor the Thermostat:
   • Keep an eye on your thermostat settings and make adjustments as needed. Use ceiling fans to help circulate cool air and reduce the load on your HVAC system.
2. Check Refrigerant Levels:
   • Low refrigerant levels can affect your system’s cooling efficiency. If you notice your system isn’t cooling as well as it should, contact a professional to check and recharge the refrigerant if necessary.
3. Inspect and Clean Drain Lines:
   • Clogged drain lines can cause water damage and reduce efficiency. Check and clean the condensate drain lines to ensure proper drainage.
4. Keep the Outdoor Unit Clear:
   • Ensure the area around the outdoor unit remains clear of debris. Trim back any plants or bushes that may obstruct airflow.
5. Listen for Unusual Noises:
   • Pay attention to any unusual noises coming from your HVAC system. Strange sounds can indicate potential issues that need to be addressed by a professional.
6. Perform Regular Filter Changes:
   • Continue to change air filters regularly, ideally every 1-2 months, to maintain optimal airflow and indoor air quality.

Fall: Prepare for the Heating Season

As temperatures start to drop, it’s time to prepare your HVAC system for the heating season. Proper maintenance can ensure your system runs efficiently and reliably during the colder months.

1. Schedule a Professional Heating Inspection:
   • Before the cold weather sets in, schedule a professional heating system inspection. A technician will check for any issues and perform necessary maintenance to ensure your system is ready for winter.
2. Replace Air Filters:
   • Just like in the spring, replace air filters to ensure proper airflow and improve indoor air quality. Clean filters can help your system run more efficiently.
3. Inspect the Heat Exchanger:
   • Have a professional inspect the heat exchanger for any cracks or damage. A damaged heat exchanger can lead to dangerous carbon monoxide leaks.
4. Check Thermostat Settings:
   • Adjust your thermostat settings for the heating season. Consider upgrading to a programmable thermostat to save energy and improve comfort.
5. Inspect and Clean Vents:
   • Check and clean all vents and registers to ensure proper airflow. Make sure they are not blocked by furniture or other obstructions.
6. Test the Carbon Monoxide Detector:
   • Ensure your carbon monoxide detector is working correctly. Replace batteries if necessary and test the device to ensure it’s functioning properly.

Winter: Maintain Heating Efficiency

During the winter, your HVAC system works hard to keep your home or business warm. Regular maintenance during this season is crucial to ensure efficiency and prevent breakdowns.

1. Monitor the Thermostat:
   • Keep an eye on your thermostat settings and make adjustments as needed. Set the thermostat to a comfortable temperature and avoid drastic changes to save energy.
2. Inspect and Clean the Outdoor Unit:
   • If you have a heat pump, ensure the outdoor unit is free of snow and ice. Clear any debris and ensure proper airflow around the unit.
3. Check and Seal Ductwork:
   • Inspect your ductwork for any leaks or damage. Sealing leaks can improve efficiency and reduce energy bills.
4. Keep the Area Around the Furnace Clear:
   • Ensure the area around your furnace is clear of any flammable materials. This can help prevent potential safety hazards and improve efficiency.
5. Perform Regular Filter Changes:
   • Continue to change air filters regularly, ideally every 1-2 months, to maintain optimal airflow and indoor air quality.
6. Listen for Unusual Noises:
   • Pay attention to any unusual noises coming from your heating system. Strange sounds can indicate potential issues that need to be addressed by a professional.

Year-Round Maintenance Tips

In addition to seasonal maintenance, there are a few year-round tips to keep your HVAC system running smoothly:

1. Regular Professional Inspections:
   • Schedule regular professional inspections at least twice a year, preferably in the spring and fall. This can help identify and address potential issues before they become major problems.
2. Maintain a Clean System:
   • Keep your HVAC system clean by regularly dusting vents, registers, and the outdoor unit. A clean system runs more efficiently and lasts longer.
3. Ensure Proper Insulation:
   • Proper insulation can help maintain a consistent temperature and reduce the load on your HVAC system. Check and improve insulation in your home or business as needed.
4. Monitor Energy Bills:
   • Keep an eye on your energy bills. A sudden increase in energy costs can indicate an issue with your HVAC system that needs to be addressed.
5. Stay Informed:
   • Stay informed about the latest HVAC technologies and maintenance practices. This can help you make informed decisions about your system and ensure it runs efficiently.
