Though your furnace installation is reliable, a furnace repair may still be necessary on occasion, and, when things go wrong, you could be without heat.
The furnace is a complex piece of machinery and so problems you may identify could be minor or more serious. If you are confident to do so, you can undertake a simple heating repair yourself (such as changing the air filter, checking fuses or readjusting the fan belt), however, always take care around electricity and gas.
