Gallagher Mechanical

At Gallagher Mechanical, we help homeowners and businesses in Pacific, Missouri, with heating, cooling, electrical, and geothermal needs. Whether you are planning new construction, remodeling, rewiring an existing property, or upgrading comfort equipment, we can help you choose a solution suited to your property and budget. We are a certified TRANE® dealership, and we also install and service most major brands.

Our electrical work includes new wiring, rewiring, remodeling projects, new construction, and system installations. For heating and cooling, we install, service, repair, and maintain furnaces, boilers, electric heaters, thermostats, and other comfort equipment. Our services include efficiency upgrades, furnace repairs and installations, emergency service, tune-ups, filter service, preventative maintenance agreements, and warranty work on most major brands. Whether you need routine maintenance, advanced diagnostics, or help deciding between repair and replacement, our technicians arrive in fully stocked service vehicles prepared to assess your system.

We also help customers explore geothermal heating and cooling. These systems use a sealed underground piping loop filled with circulating water and an ultra-high-efficiency ground-source heat pump to exchange heat between a home and the earth. If you are interested in reducing environmental pollution while saving on energy costs, our experienced geothermal technicians can explain your options and help determine what may suit your home and budget. We provide free estimates and help identify cost-efficient, energy-efficient solutions for residential and commercial properties.
