Repair Service

Emergency Repair Service Hotline: (859) 282-8300

As licensed contractors and specialists in the field of heating and air-conditioning, we have the tools, the equipment, and the experience to keep your equipment running smoothly all year long. If it is emergency service that you need, we are available to assist you, 24 hours a day, 7 days a week. To help reduce those service emergencies, we offer service agreements to keep your comfort system running at peak performance.



Before you request dealer service, check for these easily solved problems:

  • Check the indoor and outdoor disconnect switches.  Also check your main electrical panel circuit breakers or fuses.
  • Check for sufficient airflow.  Air filter(s) should be reasonably clean and interior vents should be open and unobstructed.
  • Check thermostat settings.  For cooling, your desired temperature setting should be LOWER than the displayed room temperature, and the System/Mode control should be on Cool or Auto.  For heating, your temperature setting should be HIGHER than the displayed room temperature, and the System/Mode control is set to Heat or Auto.
  • Time delays – depending on the Carrier air conditioner you have, there may be delays in unit operation that are built in to protect the equipment and your comfort.  Don’t be alarmed if you notice a time delay in operation.  It may be a standard protection feature of your equipment.  Check with you Carrier Dealer for more information on time delays.

If you need to contact your Carrier dealer for troubleshooting and/or repairs, be sure to have the model and serial numbers of your equipment available.  With this information, your dealer may be able to offer helpful suggestions over the phone or save valuable time through knowledgeable preparation for the service call. 



This furnace has a light emitting diode (LED) status code display to aid the installer, service technician, or homeowner while installing or servicing the unit.  The LED code can be seen through the view port in the blower access panel. NOTE:  Record the LED status code BEFORE removing the blower access door or turning off 115-v power to the furnace.  See the information booklet inside the main furnace door for a service code legend.

For Insufficient Airflow

  • Check for dirty air filter(s)
  • Check for blocked return-air or supply-air grilles.  Be sure they are open and unobstructed.
  • If problem still exists, call your dealer for service.

If Furnace Fails To Operate, follow this checklist step by step, advancing to the next step only if furnace fails to start.

  • Check thermostat for proper temperature.  Is thermostat set above room temperature?
  • Is thermostat set to HEAT mode?
  • Check fuses and circuit breakers.  Is the electrical power supply switch on?
  • Is the manual shut-off valve in the gas supply pipe leading to the furnace open?


  • Is control switch on gas valve in ON position?  (Follow start-up procedures if you must reset switch to ON position.)
  • Check manual reset rollout switch located on the burner box.  See furnace Components in Fig. 1 of the owner’s manual.  If furnace has experienced high temperature conditions, this switch will shut off the furnace.  Reset it by pushing the button on the switch.  If it trips again, shut down the furnace and call for service.
  • Check for obstructions around the vent termination.

If your furnace still fails to operate, call your service representative.

  • Check all electrical wiring and connections.
  • Check for secure physical connections of individual parts in each unit.
  • Operational check of the air conditioning system to determine actual working condition.  Necessary repair and, or adjustment should be performed at this time.
