My Furnace Won’t Heat My House Evenly Anymore

Your furnace should move warm air through your ducts to evenly heat your home. Bedrooms should be as warm as the living room. Your furnace is not working properly when some rooms are too warm and others are as cold as a meat locker. It is time to call a professional technician to diagnose the problem. If you need furnace repair in Levittown, PA then Gibson Heating & Cooling is the team you want to call.

Dirty or Clogged Air Filters

Before calling the professionals you should check your air filter. The air filter on a furnace collects dust and debris over time. If there is too much debris in the filter then the furnace cannot push warm air through your system. The rooms closest to the furnace will get the heat and the rooms furthest from the furnace will get little to no heat pushed through the ducts. Put a reminder in your calendar to clean or replace your filter every 1 to 3 months.

Blocked Vents

Another simple fix is to look at the vents in all rooms. Children like to play with vents. They may have placed something inside to block the airflow. Or the vent may have accidentally been closed. Obstructions like furniture, clothes, and window dressings can all restrict airflow into a room. This will cause uneven heating within the space.


A furnace that runs on shorter but more frequent cycles will cause uneven heating. The furnace does not stay on long enough to heat all the rooms. Short-cycling creates greater stress on a furnace. Over the long term, this stress can result in bigger issues requiring repair. If you notice your furnace short-cycling call a Gibson Heating & Cooling technician to diagnose the root cause.

Issues with the Ductwork

Ductwork is the complicated system of airways that allow hot air to move through your home. Dampers within the duct system open and close to direct air into different rooms. Dampers can get stuck open or closed. As a result, your warm air won’t flow as programmed by your thermostat. In addition, over time sealants on your ducts may deteriorate and start to leak. This means the hot air escapes before it reaches its intended destination. You could be paying for heat that never reaches your living space.

Faulty Thermostat

The thermostat is the brain of your entire furnace system. It measures the temperature in a room and signals the furnace to turn on or off to ensure the space is heated to the programmed temperature. A faulty thermostat leads to the furnace running at the wrong time, heating to the wrong temperature, or heating incorrect rooms in the home.

An Old Furnace

Nothing lasts forever. Uneven heat distribution could be a sign your furnace is reaching the end of its life. Especially if the furnace is more than 15 years old. An old furnace has less power to push the flow of air through the vents. Rooms furthest away from the furnace will receive less airflow. They will receive less heat.

Our Gibson Heating & Cooling technicians can solve your problem of uneven heat distribution.
