The Tune-Up

Benefits to You

1.

Check refrigerant temperatures and pressures for proper level

Makes sure your system is operating at peak efficiency

2.

Measure compressor amp draws

Ensures that your system is using the right amount of electricity

3.

Test high voltage at outdoor disconnect box

Makes sure the input voltage is adequate

4.

Inspect and tighten high-voltage connections

Helps prevent failure of circuit protectors

5.

Level and calibrate thermostat

Ensures accurate and optimal performance

6.

Inspect refrigerant fittings for leaks

Ensures that you are not leaking expensive refrigerant

7-8.

Lubricate indoor and outdoor motors

Motor runs cooler and smoother, and lasts longer

9-12.

Check wiring at furnace for loose connections

Protects electronic components from excess heat

13.

Tighten blower bolts and inspect fan

Makes sure your system is blowing as much cold air as possible

14.

Inspect and clean or replace air filters

Improves performance and keeps the air you breathe clean

15.

Inspect and adjust blower belt if applicable (can fail or wear faster)

Helps the belt last longer and perform more efficiently

16.

Inspect condensate drain to ensure the drain is clear

Prevent leaks and overflows that can cause water damage

17.

Test temperature split between supplies and return ducts

Ensures that everything is operating efficiently

18.

Check clearances around condenser to protect it from plants and shrubs

Enhances air flow around outdoor unit for peak efficiency

19.

Clean condenser coil

Keeps the coil cooler for better performance and a longer life

20.

Scrub condenser surfaces

Prevents corrosion that can shorten condenser life

21.

Tighten screws on condenser and check balance

Eliminates vibrations and lowers noise level

22.

Check compressor noise level

Helps identify and correct problems

23.

Inspect breaker for condensing unit

Bad breakers cause excessive heat and early system failure

24.

Tighten refrigerant access fittings

Ensures that expensive refrigerant is not leaking

25.

Visually inspect inside ducting for dirt and mold

Helps you keep it out of your air supply

26.

Inspect ducting and connections for air loss

This is a common cause of inefficient systems
