How Often Should I Service My HVAC System?

Keeping your HVAC system in peak condition means fewer repairs, improved air quality, and lower energy bills.
At Ethridge HVAC in Birmingham, AL, we design service schedules around our local climate and your home’s needs.
Read on to discover how often Ethridge HVAC recommends tune-ups and inspections to protect your comfort year-round.

1. Biannual Ethridge HVAC Inspections

   Schedule two full-system check-ups each year. Spring for your air conditioner and fall for your furnace. This will help catch wear and tear early.
   Our Birmingham-based technicians test refrigerant levels, clean burners, inspect safety controls, and verify thermostat accuracy.
   

   • Spring AC tune-up: condenser coil cleaning, refrigerant top-off, airflow test.
     
   • Fall furnace inspection: heat exchanger check, burner cleaning, vent safety review.
     

2. Quarterly Filter Replacements

   Every three months, replace or clean your air filters to maintain airflow and capture dust, pollen, and pet dander.
   Clean filters reduce strain on your system and improve indoor air quality.
   

   • Check monthly and replace when ¾ full of debris.
     
   • Upgrade to higher-MERV filters for pets or allergy sufferers.
     

3. Annual Safety & Electrical Checks

   Once a year, Ethridge HVAC will inspect electrical components, tightens connections, and tests safety switches to prevent hazards.
   Homeowners need to verify breaker operation and calibrate thermostats for reliable performance.
   

   • Inspect wiring, fuses, and circuit breakers.
     
   • Test limit switches and emergency shut-offs.
     

4. Seasonal Coil & Drain Maintenance

   In spring, we clean outdoor condenser coils; in fall, we clear indoor drain lines to prevent efficiency loss and water damage.
   Debris removal and line flushing keep your Birmingham system running smoothly.
   

   • Clear leaves and dirt from condenser coils.
     
   • Flush condensate lines on our Preventative HVAC Maintenance plan.
     

5. Monthly DIY Visual Checks

   Between Ethridge HVAC visits, perform quick inspections: look for blocked vents, listen for odd noises, and ensure outdoor units are clear.
   A simple visual check can reveal airflow restrictions and signal when to call Birmingham’s trusted experts.
   

   • Clean accessible coils with a soft brush.
     
   • Keep return vents unobstructed by furniture.
     

6. Smart Thermostat Calibration

   Have a Wi-Fi or programmable thermostat? Regularly ensure your setpoints match actual temperatures.
   Proper calibration maximizes efficiency and comfort control in your Birmingham home.
   

   • Sync with your Indoor Air Quality settings.
     
   • Watch for unusual temperature swings.
     

7. Biannual Ductwork Inspection

   With our preventative maintenance plans, Ethridge HVAC inspects your ductwork for leaks or blockages and seals gaps to improve airflow and efficiency.
   Well-sealed ducts prevent conditioned air loss and lower your Birmingham energy costs.
   

   • Seal joints with mastic or UL-rated tape.
     
   • Clean vent grilles to reduce indoor pollutants.
     

8. Annual Indoor Air Quality Assessment

   Each year, we review filters, inspect UV lamps, and test humidity to keep your Birmingham home healthy.
   Address allergens and moisture before they impact comfort and health.
   

   • Install UV lights on your IAQ system.
     
   • Add dehumidifiers if needed.
