How to Troubleshoot a Bryant HVAC

Heating and cooling systems can develop problems.

HVAC is a term used to describe home heating and cooling systems. The acronym stands for "heating, ventilation and air conditioning." As with any complex system, things can go wrong with a Bryant HVAC system. The company can provide a service engineer, but problems often have a simple solution, so you may want to troubleshoot the system yourself.

Things You'll Need

• New furnace filter

Instructions

Air Conditioning Problems

1. Check to ensure that the thermostat is set in the "cool" position.

2. Check the circuit breakers in the circuit breaker box to see if they're in the "on" position.

3. Check the outdoor air conditioning unit disconnect switch, which should be set to "on." The disconnect switch will be near the unit. It's usually an 8-inch-wide gray box mounted to the wall.

4. Ensure that the blower motor in the furnace is switched to "on."

5. Check the furnace filter. If it is blocked, replace it with a new one.

6. Ensure that none of the return air grilles are blocked by furniture or other items.

Gas Furnace Problems

1. Check that the thermostat is in the "heat" position.

2. Adjust the temperature setting so that it's higher than the indoor temperature showing on the thermostat.

3. Ensure there is power to the furnace. You can check this by turning on the thermostat's fan switch.

4. Check the circuit breakers in the circuit breaker box to see whether they're all set to "on."

5. Check that the SSU switch is set to "on." It looks like a light switch and is mounted on a gray box on the furnace.

6. Check the furnace filter. If it's blocked, replace it with a new one.

7. Ensure that none of the return air grilles are blocked by furniture or other items.

Tips & Warnings

• Furnace filters that are 1 inch thick should be changed monthly. Bigger filters can be changed every other month.

• Do not attempt to dismantle the system or access its electrical or mechanical components.
