When To Call Us For A Boiler Repair

You don’t need to be an engineer to know when your boiler isn’t working properly. It could be as simple as noticing your home feels a bit colder or that there’s no hot water.

Signs you should never ignore include: a smell of gas, water leaks, strange noises coming from the boiler. If you experience any of these, switch off your boiler and call us at Duffy Heating.

Another indication that your boiler needs repairing is if it stops working efficiently. You’ll notice this when your gas bill starts to creep up.
