Serving Erath County
Johnson Mechanical Services has served Dublin homes and dairy-country businesses since 1988. Our technicians handle AC repair, heating repair, HVAC installation, electrical work, and insulation throughout the Dublin area.
Dublin is about 35 miles from our Brownwood office, and our technicians travel there regularly for HVAC, electrical, and insulation work. From historic homes near the town square to properties tied to the area's dairy and agricultural businesses, we know what Dublin properties need to stay comfortable through hot summers and unpredictable winter cold fronts.
Dublin's dairy-country humidity adds extra load to air conditioning systems on top of the summer heat, and that combination shortens the life of coils and capacitors. We diagnose no-cool calls, refrigerant leaks, and failing compressors on-site and carry common parts on the truck so most Dublin AC repairs finish the same day.

We troubleshoot Dublin heating calls promptly, with careful attention to gas line and carbon monoxide safety.
Learn more about Heating RepairMany homes near historic downtown Dublin were built before modern HVAC standards and carry equipment that no longer fits the home's actual load. We size replacement systems to the home's square footage and duct condition, and every installation starts with a free in-home estimate.
