Emergency Repairs For A Forced Air System

If your residence is heated by a forced air system and heat isn't being distributed throughout your home, an emergency heating repair can be conducted with the aid of a basic assessment, some hand tools, and replacement materials. The filters, the controls, and the blower belt and fan assembly are the main areas that you will need to check and possibly adjust, clean, or replace.

Check The Condition Of The Filters

A forced air system picks up air from within the unit and pushes it out through heating ducts. A motor is used to operate this type of equipment and a series of belts may turn in conjunction with the motor running. Your heating system will contain an encased fan, which is responsible for pushing the air through the ductwork.

Before you remove the heater's casing, check the filters to determine if a blockage is contributing to the lack of airflow. A severe blockage is indicative of a dust covered filter or loose dirt particles accumulating behind the filters. If the filters are dirty, purchase new ones. Clean the bracket or casing that is designed to hold the filters in place, prior to sliding each new filter into its respective holder.

Check The Controls, The Belts, And The Fan

The comfort controls are how you adjust the heat in your home and route it to various rooms in your home. Make sure that all of the controls are programmed properly, including the thermostat. Use a screwdriver to aid with removing the heating unit's cover. Inspect the condition of the belts and the fan.

The belts should each possess a smooth surface and the rubber material should be laying flat. If the tension of each belt is too loose or too tight, use a wrench to adjust them. If either belt is cracked or torn, remove and replace them. Use a vacuum hose to suck up dust that is coating the surface of the fan blades. Use your hand to manually spin the fan, which will determine that nothing is stopping the fan from working. 

After completing all of these steps, turn your heater back on. You will hear the blower running and can check the vents in each room, to establish if heat is coming out from each one. If the problem persists, contact an HVAC contractor and provide them with a briefing of what you are experiencing. A contractor who provides residential and commercial emergency services will assess the motor and other components to determine if they are contributing to the lack of heat.
