A small crew of licensed and insured technicians handles installations, repairs, and routine maintenance. Callahan Mechanical works on both residential properties — from triple-decker homes to newer suburban houses — and light commercial sites.

Key Services

• Gas lines: gas line installation and repair for appliances and fixtures.
• Appliance service: garbage disposal repair and related kitchen plumbing.
• HVAC: system installation or replacement, routine maintenance, and system repair for cooling and heating.

Areas Served

Primary service area: Lowell MA and Chelmsford MA. Callahan Mechanical also responds to nearby neighborhoods when technicians are available. The company schedules routine work during regular hours and keeps on-call slots for emergencies.

Company History

Callahan Mechanical began as a small, local shop focused on hands-on service. Over time it added HVAC sales and installation to its plumbing roots. Growth came from repeat customers across Lowell and surrounding towns and from work on older mill-era houses that need careful plumbing upgrades. The business still keeps a neighborhood feel while handling modern systems.

Leadership

Leadership is locally based and experienced in both trades. The management team includes technicians who trained in Massachusetts and spent years in field service before moving into leadership. They participate in local trade groups and volunteer time for housing repair projects in the community. That local presence helps when planning jobs for cold New England winters and humid summers.

Specialties & Highlights

• Plumbing and AC sales, service, and installation focused on practical, long-lasting repairs.
• Experience with older Lowell homes — pipe upgrades and careful retrofit work.
• Same-week appointments for many routine jobs and emergency response when needed.
• Licensed technicians who handle both gas line and HVAC work to coordinate multi-trade projects.
