Diagnose and repair your warm air heating

Heating & Air Conditioning

Warm air heating systems are increasingly popular options for homeowners. You can buy warm air heating in Bedfordshire and elsewhere in the UK from decent suppliers at a reasonable price. They have many advantages over radiation systems, particularly in term of energy efficiency and cost savings. They also have the ability to supply consistent heat throughout your house and are much better in really cold temperatures. However, just like radiation systems, they do break down and you will have to find a way to repair them. Here’s how to diagnose and repair your warm air heating system.

If the furnace is not turning on

Warm air heaters are powered by a furnace. This is different to a boiler. A boiler, used in radiation systems, is much smaller and is used to heat water to a high temperature, causing a large amount of pressure to build up, forcing the water to be piped throughout the house. Furnaces, on the other hand, burn fuel, such as oil or gas, to heat the air directly. This is then fanned through the ducts around the house.

The basic problem of a broken warm air heating system could be to do with the electric circuits that power the furnace. In that case, the first thing you should do is check the fuse or circuit breaker so make sure there is power going into the unit. There is a service switch at the furnace or air handler which should be “on”. This will tell you if the furnace is receiving power.

Check the fuel supply to the furnace

Warm air heaters use a variety of different fuels to heat the air. You have to make sure it is being supplied with all the necessary fuel if it is going to work. If it is a gas powered furnace, the first thing you should do is make sure the gas is turned on. If the gas is being supplied through a tank or bottle – make sure it is full.

If it is an oil fuelled furnace, understand that the furnace may go off on a safety reset even if there is adequate oil. This is usually because the heating filter has been blocked by the oil causing the circuit to trip. You have to clean the filter. There is also an oil safety valve which could have been closed, and that also stops the flow of fuel to the furnace.

Fan and air filter

Another common problem is that the air is coming out is slow and the fan isn’t circulating the heat properly. This could be due to clogged filters. Check for a clogged filter full of dirt or a blocked fan. Regular servicing should clean these out and ensure your warm air heating system runs efficiently.
