How to diagnose common Goodman heating and cooling combined unit problems

Here are some heating and cooling combined unit problems you might run into, and what to do about them.

• Won’t turn on. Check the house circuit breaker for the heating and cooling combined unit to make sure it’s turned on. Reset the circuit breaker if it’s tripped. Low air flow can also prevent the heating and cooling combined unit from working, so check the air filter and replace the filter if It’s clogged with lint. Check for a clogged evaporator condensate drain pipe because a drain clog can cause the heating and cooling combined unit to shut off.
• Lack of air flow through the vents. A clogged air filter can prevent air from flowing through the vents, so replace the air filter if it’s clogged. If the filter isn’t clogged, a problem with the blower fan may be causing low air flow through the vents.
• Makes lots of noise. Bearings in the blower fan can make loud squealing or screeching noise when the heating and cooling combined unit runs. Replace the blower fan if its bearings make noise while the fan runs.
