Stampa la pagina4 - Inspect the indoor coil drain pans and condensate
drains for rust, debris, obstructions, leaks or cracks.
Pour water in pans to confirm proper drainage from
the pan through to the outlet of the pipe. Clean or
replace as necessary.
5 - Inspect and clean indoor coil, if necessary.
6 - Inspect the condition of the refrigerant lines and
confirm that pipes are not rubbing copper-to-
copper. Also, ensure that refrigerant pipes are not
being affected by indoor air contamination. Check
condition of insulation on the refrigerant lines.
Repair, correct, or replace as necessary.
7 - Inspect the duct system for leaks or other problems.
Repair or replace as necessary.
8 - Check for bearing/bushing wear on indoor blower
motor. Replace as necessary.

9 - If your heat pump is matched with a gas- or oil-fired
furnace for auxiliary heating, indoor unit service
will also include inspection and cleaning of the
burners, and a full inspection of the gas valve, heat
exchanger and flue (exhaust) system.
General System Test with System Operating
1 - Your technician should perform a general system
test. He will turn on the air conditioner to check
operating functions such as the startup and shutoff
operation. He will also check for unusual noises or
odors, and measure indoor/outdoor temperatures
and system pressures as needed. He will check
the refrigerant charge per the charging sticker
information on the outdoor unit.
2 - Verify that system total static pressure and airflow
settings are within specific operating parameters.
3 - Verify correct temperature drop across indoor coil.
