HVAC General Maintenance Tips

Here’s a handy list of HVAC general maintenance tips to keep your system running smoothly and efficiently all year long:

1. Replace or Clean Air Filters Regularly

• Frequency: Every 1-3 months, depending on usage and filter type.

  
  

• Why: Dirty filters restrict airflow, making your system work harder — leading to higher energy bills and potential damage.

  
  

2. Keep Vents and Registers Clean

• Check: Ensure vents are open and unblocked by furniture or curtains.

  
  

• Clean: Use a vacuum to remove dust and debris from registers for better airflow.

  
  

3. Check Your Thermostat

• Upgrade: Consider a programmable or smart thermostat for better control and energy savings.

  
  

• Test: Make sure the thermostat is reading the temperature accurately.

  
  

4. Clear the Condensate Drain Line

• Why: Clogs can cause water leaks and humidity issues.

  
  

• How: Flush the line with a mixture of vinegar and water every few months.

  
  

5. Inspect and Clean the Outdoor Unit (Condenser)

• Remove Debris: Keep leaves, dirt, and branches away from the unit.

  
  

• Clean Coils: Gently hose down the coils to improve heat exchange efficiency.

  
  

6. Inspect Ductwork for Leaks

• Signs: Higher energy bills, uneven temperatures, or visible dust buildup.

  
  

• Solution: Seal small leaks with duct tape or mastic sealant. For larger issues, call a professional.

  
  

7. Check Refrigerant Levels (For AC Units)

• Why: Low refrigerant can reduce cooling efficiency and damage the compressor.

  
  

• Pro Tip: Only a licensed HVAC technician should handle refrigerant checks and recharges.

  
  

8. Lubricate Moving Parts

• Components: Motors, fans, and bearings may need periodic lubrication to reduce friction and wear.

  
  

• Check: Your owner’s manual for guidance on lubrication points.

  
  

9. Test Your System Seasonally

• Spring: Test cooling mode before summer hits.

  
  

• Fall: Test heating mode before winter.

  
  

• Listen: Unusual noises like banging, hissing, or grinding may signal a problem.

  
  

10. Schedule Professional Maintenance

• Frequency: Ideally twice a year — once for cooling (spring) and once for heating (fall).

  
  

• Why: A pro can inspect electrical connections, test system performance, and spot early signs of trouble.
