How can I troubleshoot air flow problems with my central heating?


Answer by  mlucas (515)

This depends on how serious you are. The make a meter that you can check air flow with at every vent of the house. You can also get a thermoscan of your house to see which rooms are heating nicely and which arent. Also check your filter and coil.

Well, you want to make sure the air is flowing correctly. Adjust the temperatures and see what the flow of the air is like. Is it too cold or hot or just right? The signs into temperatures will allow you to assess the central heating system with more detail. There may just be a manufacturing defect.

You must first determine that the unit is running.The most common problems come from a dirty filter.That is the easiest place to start.They should be changed once a month.The second cause would be a dirty coil.A coil cleaning solution and a brush can be used to clean the coil.

First, check all of the return air filters. Standard filters be changed once per month. Once these are inspected, inspect the coils of the indoor fan unit for dust.

Make sure nothing is blocking the inside vents(e. G. Chairs, tables, beds, etc... ) and outside vents (e. G. Leaves, debris, etc.. ). Check the filters. A dirty filter may need to be changed. Other vents (like cold air ones) need to be checked for things blocking them, too. These are not connected to the ducts.

Set the thermostat temperature to above the room temperature. The furnace fan should start running. Check that the furnace air filter(s) is clean. Open all exhaust registers. If the fan is turning normally but little air is flowing, check the heating coil for clogs and check the ducting in the attic or under the floor for leaks or pinches.

The first thing I would check is the pilot to make sure everything is lit, after that it could be a world of things.

To troubleshoot air flow problems with a central heating unit one needs to close of all of the vents and then reopen them one by one to check the air flow. Sometimes a vent is clogged and restricts air flow.
