Official Goettl heating & cooling combined unit parts

What to do when your Goetti heating and cooling combined unit isn't cooling

• Check the thermostat settings. Make sure the thermostat is set to the Cool setting. Check the temperature setting and adjust it if necessary. If the thermostat isn't working, shut off the house circuit breakers for the heating and cooling combined unit and check the thermostat wiring connections. Replace the thermostat if wiring connections are okay but the thermostat won't power up.
• Check the house circuit breakers for the outside unit. Reset the house circuit breakers for the outside unit. Check the breaker on the side of the house near the outside unit and reset that breaker if it's tripped.
• Change the air filter. A clogged air filter can cause the evaporator to freeze up. Replace the air filter if it's dirty.
• Check the condensate drain line. A clogged condensate drain line will cause water to back up in the condensate drain system and trip the drain overflow float switch. The air conditioner won't cool when that drain float switch trips. Clear the clogged condensate drain line to reset the float switch.
• Clear debris from around the outside unit. Leaves and grass around the outside condenser unit can prevent the air conditioner from cooling properly. Clear any grass, leaves or other debris from the outside of the condenser unit.

Maintenance tips for your Goetti furnace

• Replace the air filter regularly. You'll typically need to replace the air filter monthly to prevent air flow restriction in your heating and cooling combined unit. Follow the instructions in your owner's manual for replacing the air filter.
• Pour 1 cup of liquid bleach through the condensate drain line to keep the line clear of clogs and algae build-up.
• Keep the outside unit clear of shrubs and grass. Trim shrubs around the outside unit regularly. Keep grass trimmed around the outside unit to prevent air flow restrictions.
• Perform annual maintenance. Have a service technician perform an annual check-up and yearly maintenance on the heating and cooling combined unit to keep it running efficiently.
