HVAC Troubleshooting and Your Bryant Heating & Cooling System

When your heating or cooling stops working, you can count on your local Bryant dealer to do Whatever It Takes® to make your home comfortable again.  However, it is always worthwhile to troubleshoot your system before calling a Bryant technician.  HVAC troubleshooting can help you save money and also time. For one, you may be able to solve the problem yourself.  If not, your analysis provides valuable information to pass along to your dealer should you need to schedule an appointment. Here are some ways to troubleshoot your Bryant heating and cooling system.

How to Troubleshoot Your Bryant Heating System

  • Check the Thermostat: If your Bryant heating system isn’t running, the first thing you should check is your thermostat.  First, make sure that the thermostat is in the ‘HEAT’ position.  Second, check the temperature setting.  For the heating system to turn on, the temperature must be set at or above the indoor temperature shown.  Finally, check the thermostat batteries.  They may need to be replaced.
  • Inspect the Furnace: Confirm that you have power to the furnace and also that the furnace is on. There is a switch box located at the furnace called the SSU switch.  It should be in the ‘ON’ position. You can also test for power by turning the fan to ‘ON’.  If there still doesn’t seem to be power, check the circuit breaker.  Make sure no switches in the electrical panel have flipped to the ‘OFF’ position. 
  • Look at Your Air Vents and Registers: If your Bryant heating system is running, but doesn’t seem to be circulating heat, then look at your air vents and registers.  Each room in your home should have an air supply register.  Check each to make sure they are open and blowing air.  Also, check to make sure that they are not blocked by furniture.  Do the same with the return air grilles.  The return air grilles are typically found on your walls. 

How to Troubleshoot Your Bryant Cooling System – HVAC Troubleshooting

  1. Check the Thermostat: If your Bryant cooling system isn’t running, look to see if the thermostat is set to ‘COOL’. Next test your thermostat batteries.  They may need to be replaced. If your system is running but not cooling, double-check that your thermostat isn’t in direct sunlight. This can cause your system to read the wrong temperature. Also, make sure that the temperature setting is set at or below the indoor temperature shown. 
  2. Analyze the Circuit Breaker:  Locate the electrical panel in your home and make sure all switches are in the ‘ON’ position. If the circuit breaker to your AC is tripped, firmly push it into the ‘ON’ position and check to see if your AC starts running. If the breaker immediately trips again, have a professional look at it.
  3. Survey the Condensing Unit: Locate your outdoor air conditioning unit.  Ensure that there are no large objects with 2 to 3 feet of your unit.  Also, make sure that no dirt and leaves have built up around the outside AC unit.  A buildup of debris can cause inadequate cooling.  Sweep away any leaves and also gently hose off any small amounts of dirt. Also, make sure the ‘disconnect switch’ located near the outdoor unit, usually mounted to the house, is in the ‘ON’ position.
  4. Inspect the Filter: Over time, dust builds up on an HVAC filter. This blocks the airflow, reduces efficiency, and can even cause your HVAC system to stop.  Most Bryant HVAC systems need their air filters changed every couple of months. If you haven’t changed your filter recently, do so.
  5. Look at Your Air Vents and Registers: If your Bryant cooling system is running, but doesn’t seem to be circulating much cold air, then look at your air vents and registers.  Make sure air is flowing from air vents, and that neither are blocked by furniture or long drapes.
