No Warm Air From A Gas Furnace: The Cause & Solution

Are you dealing with not getting a sufficient amount of warm air when the heater is on? Although there are several areas of the heating system that can cause the problem, the first thing that should be inspected is the furnace. Find out below why a gas furnace can stop producing warm air, as well as what kind of repair might be necessary to fix the problem.

What Causes a Gas Furnace to Malfunction?

Before you will know why your gas furnace is not producing warm air, you must first understand how it works. The first thing that a gas furnace does is take in the cool air that is circulating in your house to clean it with a filter. The cool air is then heated by way of the gas burner on the furnace. The warm air is then sent into a blower that distributes it through the air ducts to heat your home to the temperature on the thermostat.

When a gas furnace fails to produce warm air, it is possible that the pilot burner is not functioning the way it should. It is also possible that the blower motor has stopped working to send air through the air ducts. The air ducts can interfere with air flow if they are dirty. Rodent carcasses can also be in the air ducts and interfering with how much warm air your home is receiving from the furnace.

What Kind of Repair Might a Gas Furnace Need to Produce Warm Air?

Repairing a gas furnace may involve lighting the pilot, but it should be done by a heating specialist for your safety. The reason is due to the furnace being run by gas, which must be at a specific level when the pilot is being lit. Too much gas can lead to an explosion.

It is also possible that a specialist will have to inspect the blower to determine if it is causing the lack of warm air in your home. If the blower is dirty, it will be cleaned. If the blower motor has stopped working, the specialist can replace it. However, it is also possible that you need a new furnace.

The lack of warm air from your heating system may only require a minor repair. Get in touch with a specialist, such as Capital Heating & Cooling, to get your gas furnace inspected and repaired as soon as possible so you can enjoy warm air again!
