According to the U.S. Department of Energy, an improperly installed HVAC system can reduce its efficiency by as much as 30%. Yikes. As spring arrives, now is the ideal time to make sure your HVAC system is running properly and ready for the demands of warmer weather. Appropriate maintenance can extend the life of your equipment and reduce energy consumption.
1. Replace or Clean Air Filters
We emphasize this on our blog because replacing or cleaning air filters is one of the simplest yet most effective maintenance tasks you can do. Dirty filters restrict airflow, forcing your system to work harder and consume more energy. For optimal performance, check filters monthly and replace them every 1-3 months depending on usage and filter type.
2. Clear Debris Around Outdoor Units
Winter often leaves outdoor condensing units surrounded by debris. Remove leaves, twigs, and other buildup from around the unit. Make sure there is at least two feet of clear space on all sides. Trim back any encroaching vegetation to maintain proper airflow.
3. Check and Clean Evaporator Coils
Indoor evaporator coils also require attention. While these accumulate less debris than outdoor coils, they can still collect dust and affect system performance. Have a professional clean these during your annual maintenance visit.
4. Inspect and Clean Condensate Drain Line
A clogged condensate drain can cause water damage and humidity problems. Flush the drain with a vinegar solution to prevent algae growth and ensure proper drainage.
5. Test Thermostat Functionality
Verify that your thermostat accurately reads temperature and properly communicates with your HVAC system. Consider upgrading to a programmable or smart thermostat if you haven’t already to improve comfort and efficiency.
6. Examine Ductwork
Inspect visible ductwork for signs of leaks, separations, or damage. Leaky ducts can significantly reduce system efficiency and indoor comfort. Seal any detected leaks or have a professional address more significant issues.
7. Check Refrigerant Levels
Low refrigerant levels indicate a leak that requires professional attention. A properly trained technician can check levels and repair any leaks found in the system.
8. Lubricate Moving Parts
Motors and bearings in your HVAC system need lubrication to reduce friction and prevent overheating. A professional can identify which components need lubrication and apply the appropriate amount.
9. Schedule Professional Maintenance
While many maintenance tasks can be performed by homeowners, an annual professional inspection is invaluable. HVAC technicians can identify potential problems before they become costly repairs and perform specialized maintenance that requires technical expertise.
10. Test System Operation
Finally, run your system through a complete cooling cycle to make sure everything functions properly. Listen for unusual noises, monitor the airflow from vents, and check that the system maintains the set temperature.
By following this checklist, you can make sure that your HVAC system operates efficiently during the warmer months ahead. This will help you save some money on energy costs and also extend the life of your equipment. If you have any questions about your air conditioning system, please get in touch with us today.
