About US
Founded nearly 40 years ago by Peter McAleer and Brendan McGarrity, McAleer & McGarrity has grown into one of the region’s most respected names in mechanical and HVAC contracting.
Operating throughout Northern Ireland, the Republic of Ireland, England, Scotland, and Wales, we deliver high-quality, energy-efficient mechanical systems that meet the demands of modern construction and design.

Every project we undertake reflects the same dedication to precision, safety, and reliability that has earned us the trust of contractors, developers, and consultants across multiple sectors.
Our Story & Approach
At McAleer & McGarrity, collaboration is at the core of everything we do. We work closely with clients, architects, and design teams from the early planning stages through to commissioning and aftercare. Our experienced engineers and technicians take a practical, solutions-driven approach — ensuring every system we install performs efficiently, complies with regulations, and stands the test of time.
Whether it’s a large-scale commercial development, a public sector building, or a specialist refurbishment, we bring the same attention to detail and commitment to excellence to every project.
