Furnace Installation, Repairs & Maintenance

By contacting Callahan Heating and Cooling, we will find the right solution to keep you and your family warm and safe throughout the winter season.

Furnace Repairs

Furnaces are complex machines with various components such as motors, fans, flame rectification systems, sensors, igniters, gas valves, controls, and bearings. When one part fails, it can trigger additional failures or even a complete system breakdown.

Common Furnace Service Calls

Our team frequently handles service calls for issues such as dirty filters, furnace pilot light ignition problems, burners that won’t stay lit, blower motors that won’t shut off, lack of airflow from the blower, malfunctioning thermostats, unusual sounds coming from the furnace, and empty propane tanks.

Furnace Replacement

Over time, every furnace system will require replacement, particularly older units that consume excessive energy. In most cases, replacing your furnace can lead to significant savings on utility bills and eventually pay for itself. We understand that choosing a replacement system is an important decision. Therefore, when we visit your home, we will help you find a reliable unit that suits your needs and budget.

What to do if your furnace has stopped working

If your furnace has stopped working, follow these steps to troubleshoot and resolve the issue:

1. Check for a Diagnostic Code: Locate the sight glass on the blower door of your furnace. Look inside and see if there is a diagnostic code flashing. If you see a diagnostic code, it means that the furnace has locked itself out, and you should call for professional service. Use your smartphone to record a one-minute video of the diagnostic lights to show the technician when they arrive.

2. Reset the Circuit Breaker: Locate the circuit breaker for your furnace and check if it has tripped. If it has, try resetting it. If the breaker immediately trips again, this indicates a direct short in the furnace circuit. Call for professional service immediately to prevent further damage.

3. Check Thermostat Settings: Verify that your thermostat is set to heat and that the set point is higher than the current room temperature. If it has been more than a year since you last changed the batteries in your thermostat, replace them.

4. Propane Furnace: If your furnace runs on propane, check the propane tank to ensure that it has more than 5% fuel remaining.

5. Reset the Furnace: If you have recorded the diagnostic code with your phone, turn off the furnace breaker for one minute and then turn it back on. If the furnace starts working again, it means that you cleared the error from the circuit board. However, the issue may not be permanently fixed, so send the video of the diagnostic lights to your technician for further analysis. Remember, if the furnace locks out again before the technician arrives, do not reset it again.

If Your Furnace is Running but Blowing Cold Air:

1. Change Air Filters: Replace the air filters in your furnace, as dirty filters can restrict airflow and cause the furnace to blow cold air.

2. Check Fan Settings: Verify that the thermostat fan setting is not set to run constantly, as this can cause the furnace to blow cold air. Set it to auto instead.

3. Schedule Furnace Repair: If you have changed the filter and the furnace continues to blow cold air, there may be a safety switch tripping. Contact a professional furnace repair service to schedule an appointment.

If Your Carbon Monoxide Detector Goes Off When the Furnace Turns On:

1. Ventilate the Space: Open windows to allow fresh air to circulate and ventilate the area.

2. Shut Off the Furnace: Turn off the furnace at the thermostat.

3. Contact Emergency Services: If necessary, call the fire department. Then, contact a professional service to schedule an emergency service call.

If You Smell Gas in Your Home:

1. Strong Smell: If there is a strong smell of gas, do not use any electronics, leave the building immediately, and call your local fire department or city utilities to shut off the gas supply.

2. Faint Smell: If you detect a faint smell of gas, turn off the furnace at the thermostat, open windows for ventilation, and contact a professional service to schedule an emergency service call.

Note: All gas leaks should be taken seriously, and you should not attempt to repair them yourself. Contact the appropriate authorities immediately.
