Common Signs of Furnace Troubles

Your furnace controls the temperature of your home and provides you with heat in winter and on cooler days. Whether you have forced air heating or a duct system, you can turn the furnace on and off and change the temperature with your thermostat. Forced air heating uses large open vents that let warm air rise, while duct systems use blowers to push the warm air through the house. There are some common signs of furnace troubles that might indicate you need to call a repair company.

Unusual Noises

Houses make odd noises as the foundation settles and the house goes through temperature changes. You may even notice that your furnace makes some loud noises when it kicks on after adjusting the thermostat. While some noises are fine, other noises can indicate a serious problem. This includes a loud knocking or banging sound that comes from the furnace or a soft ticking sound. The noises can become so loud that you can hear the furnace running from anywhere in your home.

Lack of Temperature Control

Thermostats consist of a series of small numbers and a dial or lever that lets you increase or decrease the temperature. After adjusting the thermostat, you should hear the furnace kick on and notice warm air coming through your vents. If your thermostat does not send a signal to the furnace, it might be time to get in touch with a Pittsburgh heating & furnace repair company to repair your furnace.
