Common Types of Furnace Trouble


Fall is here and nighttime temperatures are becoming quite chilly. To stay nice and cozy in your home, you need your heating system to work efficiently. At the first sign of furnace trouble, it'll be best to have an HVAC professional come by to inspect the matter. At Blue Ice Air Conditioning and Heating, our HVAC technicians are highly experienced with identifying and fixing furnace issues. Don't hesitate to give us a call when you need furnace service in Costa Mesa.

Damaged Heat Exchanger

It's important that your heat exchanger is working properly so that the combustion process is safely separated from your breathing air. Overheating your house increases the chances of a heat exchanger becoming cracked. A cracked heat exchanger typically requires replacement.

Clogged Filter

A clogged filter can cause inefficiency by reducing the intake your furnace needs for optimal operation. When temperatures dip in the winter and you're regularly using your furnace, it's best to change your filter every month.

Problem with Blower Belt

For the fan to run reliably, the blower belt needs to be working properly. A faulty blower belt can create a squealing sound. After years of regular use, blow belts often wear down to the point that they break or fray, at which point you'll probably need belt replacement rather than repair.

Faulty Thermostat

An issue with your thermostat can cause the fan to continuously operate. If your thermostat battery continuously runs, then your furnace probably won't function as efficiently as it should. Also, short cycling is a sign that it's time for a new thermostat.

Pilot Light Trouble

If your pilot light is burning any color other than bright blue, then you'll want to alert an HVAC technician. In your gas furnace, this could be a sign of excessive carbon monoxide. An orange or yellow flame could mean that a lack of oxygen is causing inefficient burning.
