Gas Boiler Services
Gas Boiler Services in Ireland
A boiler that won’t fire up on a cold morning isn’t just inconvenient, it’s usually a sign something’s been ignored for too long. Cunningham Mechanical Services handles gas boiler repair and maintenance for homes and businesses across Castleblayney, Monaghan, and the wider region, with engineers who actually explain what’s gone wrong instead of just handing you a bill.
We work on all major boiler brands and models. Whether it’s a slow leak, a pressure fault, or a system that’s just given up entirely, our team gets to the root of the problem rather than patching it temporarily.
Gas Boiler Repair and Maintenance
Boilers rarely fail without warning. Strange noises, pilot lights that won’t stay lit, uneven heating around the house — these are the early signs, and catching them early is cheaper than waiting for a full breakdown in January. Our maintenance visits cover a full inspection of the flue, pressure valve, thermostat calibration, and internal components, so small issues get fixed before they become expensive ones.
For households on a proactive maintenance plan, annual servicing is built in, which keeps warranties valid and extends the life of the unit considerably.
Gas Boiler Repair Ireland — Fast, Reliable Callouts
We know a broken boiler in winter isn’t something that can wait a week. Our engineers cover callouts across Monaghan and Castleblayney with same-week appointments in most cases, and every job comes with an honest diagnosis before any work starts — no guesswork, no unnecessary parts.
If your issue can’t wait, our emergency plumbing services team is also on hand for anything that overlaps with your heating and water system.
Why Choose Our Registered Gas Installers
Every engineer we send out is RGI-registered and fully insured, which matters more than people realise until something goes wrong with an uncertified job. We also carry parts for most common brands, so many repairs are completed in a single visit rather than requiring a second callout once parts arrive.
Beyond boilers, we handle the full picture of home comfort, from heating system installation to general plumbing services. So if a boiler issue turns out to be connected to your wider heating setup, we can deal with it in one visit rather than passing you between contractors.

How often should a gas boiler be serviced?
Once a year is the standard recommendation, ideally before the heating season starts in autumn. It keeps the manufacturer’s warranty valid and catches faults before they turn into breakdowns.
How quickly can you attend a boiler breakdown?
Most callouts in the Castleblayney and Monaghan area are attended within the same week, and urgent cases are prioritised. Get in touch and we’ll give you a realistic timeframe based on your location and the issue described.
Do you repair all boiler brands?
Yes. Our engineers are trained across the major residential and commercial brands used in Ireland, and we stock parts for the most common models.
What's the difference between a repair and a full replacement?
If the boiler is under 10-12 years old and the fault is isolated, repair is usually the more economical route. Beyond that age, or with repeated faults, we’ll walk you through whether heating system installation makes more financial sense long-term.
Do you offer emergency gas boiler repair?
Yes, for no-heat or no-hot-water emergencies, we prioritise same-day attendance where possible. Call our team directly to flag urgency.
