Air Conditioning & Conditioner Troubleshooting

AC Troubleshooter Guide

-by Michael, Austin Air Conditioning company, Autumn Heating & Cooling, President.

No Power to System: Possible Causes

• Fuse blown, either at main home service panel, or on AC system
• Wiring to system is faulty
• Main system has gone into safety interrupt due to blocked air blower

No Cooling Power – But System Blows Hard

-This indicates a proper functioning filter and blower system, but a failure in the refrigeration system.

-Refrigerant needs to be recharged

-Refrigerant tubing/piping has sprung a leak

-Outside condenser motor or pump have blown–check if outdoor motor is running

No Cooling Power – System Blows Weak

-Most likely: Filters need service and repair (Call Us!)

-Air handler/blower motor is burnt out

-Air handler/blower is clogged

-Air ducts need to be cleaned

-Indoor coil is clogged or has iced up

System Noises

-Grating, grinding noises are nearly always the failure of a blower motor.

-Excessive air noise can be caused by dirty ducts or blocked ducts (construction debris or loose parts)

Maintenance & Performance Tips:

-Keep those filters clean (with regular AC service from Autumn Heating & Cooling)

-Keep vegetation away from outdoor condensers–condensers need to “breathe” to expel heat efficiently

-If possible, outdoor condensers should be in a shaded area (don’t cut back a tree that shades a condenser)

-Observe regular maintenance (you can contact us for maintenance quotes)

-Indoor air vents, if too many are shut, reduce overall system performance and efficiency
