Our HVAC INSPECTION and Indoor air quality report

  1. Thermostat – test for proper operation
  2. Check condition of existing air filter 
  3. Inspect indoor coil if accessible
  4. Confirm proper return air and size
  5. Inspect Condenser Coil
  6. Refrigerate levels – monitor operating pressures
  7. Safety Devices – inspect for proper operation
  8. Test/inspect contactors for burned, pitted contacts
  9. Inspect electrical for exposed wiring
  10. Inspect capacitors
  11. Inspect fan blade
  12. Measure Supply/Return temperature differential
  13. Compressor – monitor, measure amperage and volt draw and wiring connections
  14. Inspect all fittings for signs of oil leakage
  15. Check the integrity of the ductwork 

 

 After the 15 point check up we will check refrigerant charge which includes: Measure the temperature drop across indoor coil, superheat value and sub-cooling value as recommended by manufacturer.

Why is the Superheat and Subcooling and Delta T is so important?

They help us evaluate the health of an air conditioning system. 

 Generally speaking, when superheat, subcooling, SST, and delta T are within normal ranges, we can be fairly sure that airflow is correct and the system charge volume is correct. When one or more of the measurables are out of line, we can use those observations to begin drawing conclusions about what our diagnosis might be.  

What Gauges do we use for the HVAC inspection?

 The SMAN460 wireless four-port digital manifold is the top-of-the-line Fieldpiece manifold.  It has more features and benefits than any other manifold on the market.  With target superheat automatically calculated, simultaneous superheat and subcooling, all 9 measurements displayed on the large, easy-to-read screen, extra large 3/8' full bore and 4th VAC port, and wireless measurements for real-time system diagnosis and charging, the SMAN460 is the manifold HVACR pros trust to do more. 


Some of the SMAN 460 Features are:

  • Measures:
    - 2 Pressures
    - 2 Temperatures
  • Calculates:
    - Superheat
    - Subcooling
    - Target Superheat
    - Vapor Saturation
    - Liquid Saturation
