A boiler that won’t fire up on a cold morning isn’t just inconvenient. It usually means something’s gone unnoticed for too long. That’s why Cunningham Mechanical Services handles gas boiler repair and maintenance for homes and businesses across Ireland, with our engineers based in Castleblayney, Monaghan, and covering the wider region from there.
We work on all major boiler brands and models, so whether it’s a slow leak, a pressure fault, or a system that’s given up entirely, our team finds the root cause instead of patching it temporarily.
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 costs far less than waiting for a full breakdown in January. During a maintenance visit, we inspect the flue, check the pressure valve, calibrate the thermostat, and go through the internal components, so small issues get caught before they turn into expensive ones.
If you’re on one of our proactive maintenance plans, we build annual servicing straight into your calendar, which keeps the manufacturer’s warranty valid and adds years to the unit’s working life.
A broken boiler in winter can’t wait a week, and we don’t expect you to. Our engineers cover callouts across Monaghan, Castleblayney, and beyond, with same-week appointments in most cases. Every job starts with an honest diagnosis before any work begins, so there’s no guesswork and no unnecessary parts added to the bill.
For anything that genuinely can’t wait, our emergency plumbing services team also covers issues that overlap with your heating and water system.
Every engineer we send holds full RGI registration and carries full insurance, which matters more than most people realise until something goes wrong with an uncertified job. We also stock parts for most common brands, so we complete many repairs in a single visit instead of booking a second one once parts turn up.
Beyond boilers, we cover the full picture of home comfort, from heating system installation to general plumbing services. So if a boiler issue connects to your wider heating setup, we can sort the whole thing in one visit rather than passing you between separate contractors.
Our skilled plumbers offer comprehensive plumbing solutions, including installation, repair, and maintenance services.
Keep your home or business warm and cozy with our professional heating services.
Design, Adaptation and Installation services. Collaboration with family members and health services.
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.
We prioritise urgent callouts and aim to reach you within the week in most cases, sometimes sooner depending on your location and the issue described.
Yes. Our engineers train across the major residential and commercial brands used in Ireland, and we stock parts for the most common models.
If your boiler is under 10-12 years old and the fault is isolated, repair usually makes more financial sense. Past that age, or with repeated faults, we’ll talk you through whether a full heating system installation is the better long-term option.
Yes. For no-heat or no-hot-water emergencies, we prioritise same-day attendance wherever possible, so call our team directly and flag the urgency.
