Troubleshooting Common HVAC System Problems

image When your air conditioning or furnace isn't functioning correctly, it can be frustrating and worrisome. However, you do not necessarily need to bring in a professional right away. There are some things you can check on your own before calling the experts at Hammond Services:

1. Does the furnace or air conditioner unit have power? Check to see if a circuit breaker was tripped or if fuses are broken or blown. Turn it off and back on again.

2. Does the thermostat have power? If it's battery-operated, try replacing the batteries. If it's tied to the electrical system, check to see if the breaker for the thermostat needs to be re-set.

3. Are the registers open and is the fan "on"? As basic as it sounds, check to see if the unit is on and if air can get through the registers. 

4. Can you force the heat or air conditioning to come on? Try adjusting the temperature. Turn on the furnace and set it for a higher temperature (3-5 degrees higher), or the air conditioning (3-5 degrees lower). After 30-60 seconds, if it is working, you will have air coming through the registers. 

5. Is the panel door on the furnace closed completely? If the door came open somehow, the furnace will not operate. You may be able to re-set it by opening the door and pushing the reset button or turning the gas off and back on, following the directions in the owner's manual for the unit.

6. If your air conditioner isn't working, is there water below the unit? If so, dirty coils may have caused the coils to freeze up. Turn the unit off and wait 3-4 hours before trying to clean off the coils and restarting the unit.

7. Is the outdoor condenser unit clean and free of debris?
Dirt, weeds, insects or wildlife can wreak havoc on outdoor air conditioning condenser units. Just as the indoor coils need to be kept clean, the outside unit also should be kept clean and free of debris. 

8. Does the filter need to be cleaned or replaced?
A dirty filter can significantly impact the efficiency of your furnace or air conditioner, and cleaning or replacing it could fix the problem.
