A lack of heat may be caused by...

A clogged air filter

The furnace's air filter has one primary responsibility: to protect the furnace from contaminates and particles, which have the potential to cause significant damage if they enter the system. When your air filter becomes too clogged, airflow in and out of the furnace is restricted, causing the system to overheat. Since the majority of warm air is trapped inside of the furnace, it is unable to reach your vents, which is when you begin to notice a lack of heat. It is important to change your air filter every 1-3 months during the heating season. A clogged air filter can produce a whole slew of issues, so it is necessary to have them replaced.

A faulty thermostat

Sometimes the problem might not be with the furnace itself but rather with the thermostat. When the thermostat is broken, there is a chance that your furnace might be shutting down before the desired temperature is met. Only a trained professional will be able to determine the source of the issue. Luckily, thermostat repairs tend to be less costly than furnace repairs.

A breach in the ductwork

When your ductwork is properly sealed, it is able to retain proper air pressure to send warm air throughout your home. A breach in the system significantly reduces air pressure inside the system, meaning warm air might not be able to reach your vents. In addition to leaks, your ductwork is at risk for clogs or blockages, which makes it harder for your furnace to push warm air through the ventilation system and raise heat levels in your home.

A broken blower motor

The furnace's blower motor is the mechanism responsible for blowing warm air throughout the home. If this essential piece of your furnace is broken, you can definitely expect a lack of heat. Without this mechanism, your furnace would not be able to circulate heated air. Don't hesitate to contact our technicians at Air Mechanical if you've noticed a lack of heat this winter. We want to restore your furnace's function to keep you warm and cozy throughout the remainder of the winter.
