Winter is just around the corner, and soon you’ll be needing to get the most out of your furnace. 

Is your furnace working to its full capacity right now, or does it need some work doing? It’s relatively common to need to carry out furnace repairs on your heating system. 

Here are five of the most common furnace repairs

1. Replacing the Filter 

The filter on your furnace helps to keep everything running smoothly. It removes dust, pollutants, allergens, and any other airborne debris. This helps to keep the air in your house clean. 

These filters need changing regularly. How often you need to change them will depend on the type of filter, and you can check the packaging for your current filters for information on when they need to be changed. 

As a general rule, if your furnace feels like it is working a lot harder than it needs to be, your filters probably need replacing. 

2. Fixing the Thermostat

Occasionally it’s not the furnace itself that needs fixing but the thermostat

Your thermostat tells your furnace when to heat the house and when not to. It’s also the interface that you use to set the temperature of your home. It’s an essential part of your heating system. 

If your thermostat isn’t working correctly, you can call a professional to come and assess it. They will look at whether the problem is with the software or the hardware, and they will either fix the problem or replace the faulty thermostat with a brand new one.

3. Cleaning the Ducts

Your heating system will have several ducts that allow hot air in and out of a specific room or area. It’s important to keep these clean. 

If debris blocks any of these ducts, then it can prevent the hot air from travelling around your home efficiently. 

If you have a routine maintenance deal with an HVAC maintenance service, they will be able to clean the ducts for you whenever you have your regular appointment. If you don’t, simply get in touch with a technician and they’ll be happy to come round and clean the system for you. 

4. Repairing the Starter Mechanism

Your furnace will have a starter mechanism on it that is responsible for kick-starting your heating system. In older systems, this starter mechanism is most commonly a pilot light, but newer systems have an electrical ignition. 

If these starter mechanisms fail, your furnace won’t start up or begin the heating cycle, and the entire system will cease to work. If your starter mechanism is broken, you will need to call a technician who can fix or replace the ignition.

5. Maintaining the Heat Exchanger 

The heat exchanger is the using hero of your heating system. It is the component of the system that is responsible for moving the heat from inside your furnace to the rest of your home. 

If you don’t look after the heat exchanger, its tubes will begin to degrade and crack and can hinder the whole system. If this happens, it’s best to call out a heater repair service that can come and fix or replace the exchanger.
