Air Conditioner Troubleshooting

Air Conditioning Equipment Checklist 
Check to make sure that your thermostat is set in the "cool" position. 
Ensure that your outdoor air conditioning (condensing unit) is running. Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to an outside wall in the back of the house. Make sure they are all in the "ON" position. Check the outdoor unit "disconnect switch" to make sure it is in the "ON" position. The disconnect switch is located near the outdoor unit. (Normally a grey 8" wide x 16" high x 4" deep box mounted to the wall). 
Ensure that the blower motor in your furnace is running. (If the thermostat is in the "cool" position, the furnace blower should be running.) If not, check to make sure the on/off switch at the furnace is in the "ON" position. 
Be sure that you have changed your filter in the furnace recently. An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow. 
Check all return air grilles to make sure they are not blocked by furniture. Furniture should be moved at least four inches away from return air grilles to allow for adequate air supply. 
 
Find Your Model Number 
Knowing the model number of your Bryant products will help you troubleshoot any problems and will make it easier for your Bryant dealer to provide service. 
In addition to being listed in your owner’s manual or other paperwork that came with your Bryant product, the model number is also posted directly on your unit. Here’s how you find it: 

Air Conditioners and Heat Pumps: You can find the model number listed on a “rating plate” sticker on the unit above the back-seated service valve connections. 
Gas or Oil Furnaces: Remove the front door and look at the upper-left side of the unit. You can find the model number listed on a “rating plate” sticker inside of the unit. 

If you have a different Bryant product, look for a “rating plate” sticker on the unit. And of course, if you are unable to find your model number, you can always call your Bryant dealer.

Furnace Troubleshooting

Not heating?  
Most likely, either the electrical system providing your furnace’s power has shorted or the power switch has blown. Try resetting your furnace’s circuit breaker. If it has blown, you will need to replace it. 
The furnace’s igniter might either be cracked or faulty. Check the part for cracks, if it is then replace the igniter. If it isn’t cracked, use a multimeter to test for continuity. 

Cycling irregularly?  
Your thermostat might be adjusting incorrectly, causing the furnace to cycle on and off too often. If your thermostat has an adjustable calibration scale, adjust the heat anticipator. If this does not stabilize the unit, you may have to replace the thermostat. 

Not blowing hot air?  
Your blower motor may have completely burnt out. If this doesn’t seem to be the case, then the connecting belt may have simply broken. Test to see if power is reaching the motor. If it does, but isn’t running, the motor has likely failed. If the motor runs but air doesn’t move, the connecting belt has probably broken. You’ll have to replace the belt. 

Blowing too much air?  
The control board regulates the amount of voltage that reaches each functioning part. If the relay that controls the blower motor has failed, it will continually send voltage to the motor. Replace the control board. 
The contact that controls the blower motor on your thermostat may be stuck closed, causing the blower motor to run continuously. Use a multimeter to check for continuity. If it appears the thermostat is the issue, replace it. 

Leaking water? 
Check the drain pipe. 

Starting and then stopping shortly after?  
Your furnace’s flame sensor monitors the burner, detecting whether a flame is present. If it is either defective or dirty, it will not be able to detect a flame. If dirty, clean the sensor using a fine abrasive pad. If faulty, replace the flame sensor.

Heat Pump Troubleshooting

Check the thermostat settings: Make sure the thermostat is set to the desired temperature and operating mode (heating or cooling). Ensure that the system is not in "Emergency Heat" mode, as this bypasses the heat pump and uses auxiliary heat sources instead.

Verify power supply: Ensure that the heat pump is receiving power. Check the circuit breaker for the heat pump and make sure it hasn't tripped. If it has, reset it and monitor to see if it trips again. If it does, there may be an electrical issue that requires professional attention.

Inspect the air filters: Dirty or clogged air filters can restrict airflow and reduce the heat pump's efficiency. Check and clean or replace the filters as needed. Refer to the manufacturer's instructions for guidance.

Clear the outdoor unit: Ensure that the outdoor unit is free from debris, such as leaves, dirt, or snow. Clear any obstructions that could restrict airflow or damage the unit.

Check for ice buildup: During colder weather, ice can accumulate on the outdoor unit's coils. If you notice excessive ice buildup, it may indicate a problem with defrosting. Switch off the heat pump and allow the ice to thaw before turning it back on. If the problem persists, consult a professional technician.

Inspect the indoor air vents: Make sure all supply and return air vents are open and unobstructed. Blocked vents can restrict airflow and affect the heat pump's performance.

Check for unusual noises: Listen for any unusual noises coming from the heat pump during operation. Unusual sounds may indicate mechanical issues or loose components, requiring professional attention.

Verify the temperature differential: Measure the temperature of the air entering the return air vent and the air exiting the supply air vent. The temperature difference should be within the expected range. If there is a significant difference, it could indicate a problem with the heat pump.

If you have followed these troubleshooting steps and are still experiencing issues with your heat pump, it's recommended to contact a qualified HVAC technician. They have the expertise and tools necessary to diagnose and resolve more complex problems.
