Detailed Breakdown

1. Thermostat Calibration and Communication Check

The thermostat is the command center of your HVAC system. During an evaluation, technicians check for calibration accuracy, make sure it’s communicating with the HVAC unit, and verify the programmed settings.

• A faulty thermostat can cause your system to short cycle or run constantly.
  
• Smart thermostats are also tested for connectivity and sensor accuracy.
  
• Proper calibration ensures you’re not wasting energy or sacrificing comfort.
  

Homeowners upgrading to smart thermostats can explore  additional HVAC services that integrate modern controls with older systems.

2. Airflow and Ductwork Assessment

Poor airflow leads to uneven temperatures, high energy bills, and excessive strain on the HVAC system. Evaluations include checking ductwork for leaks, blockages, and pressure imbalances.

• Leaky ducts can waste up to 30% of heated or cooled air.
  
• Technicians use tools like manometers and smoke pencils to assess airflow.
  
• This helps ensure rooms are heated and cooled evenly—a must for Yucaipa’s larger family homes.
  

If problems are found, your HVAC contractor can recommend repairs, sealing, or upgrades to your duct system.

3. Filter and Coil Condition

Clogged filters or dirty coils are the usual suspects behind sudden system inefficiency. During a full-system check, your HVAC pro inspects and, if needed, replaces filters and cleans both evaporator and condenser coils.

• Dirty coils reduce heat exchange efficiency and can cause the system to overheat or freeze.
  
• Filters are evaluated based on usage, pet presence, and air quality concerns.
  
• Clean filters and coils are especially important during wildfire season or heavy pollen months in the Inland Empire.
  

Regular HVAC maintenance from  Aloha Plumbing, Heating & Air includes filter checks as part of the service, not an add-on.

4. Refrigerant Levels and Pressure Testing

Refrigerant is essential for cooling your home, and incorrect levels can indicate a leak or overcharge—both of which can cause compressor damage.

• HVAC contractors measure refrigerant pressure and check for proper charge.
  
• If low, the system is checked for leaks using electronic detectors or dye tests.
  
• Proper refrigerant balance protects the compressor and ensures efficient, cold airflow on hot Yucaipa days.
  

Technicians also make sure the system is compliant with EPA refrigerant standards, especially for older units.

5. Electrical Connections, Safety Switches, and Moving Parts

Lastly, the evaluation wraps up with a thorough inspection of wiring, capacitors, motors, fans, belts, and safeties. These parts are the heartbeat of your HVAC system.

• Loose wires can be a fire hazard or lead to blown components.
  
• Capacitors and motors are tested for startup strength and efficiency.
  
• Blower motors and fans are lubricated and tested for balanced performance.
  

This full checklist ensures your system isn’t just running—it’s running safely and efficiently, which is crucial in peak summer or winter use.
