Master Mechanical has worked out of Spring Hill since 2014, installing and repairing the systems that keep Middle Tennessee homes and businesses running.
Since 2014 · Spring Hill, TN
Most homes run on four systems, and most homeowners keep a different contractor for each. Master Mechanical is a locally owned crew that carries all four: heat and air, plumbing, electrical and gas. When the condenser quits and the breaker beside it is tripping too, that is one visit, not two appointments and a week of phone tag.

Heat & air · plumbing · electrical · gas
The MM shirt lists all four trades because the crew wearing it works all four. The tech who opens your condenser's control box is the same one who can look at the panel feeding it, the water heater in the garage and the gas line behind the furnace.
The four lines
Residential and commercial work across Spring Hill, Columbia and the rest of Middle Tennessee. Every trade has its own page with what goes wrong, how we work and what to watch for afterwards.
Line 1 · Heat & air
Installation, service, maintenance, repair and replacement, residential and commercial. This is the package unit we set on a fresh pad beside a new brick home: line set run, ductwork boot staged on top, ready to be tied in.
Heating & air
Line 2 · Plumbing
The same crew that services your system handles the water side of the house: supply lines, shutoff valves, water heaters and the slow leak at a fitting that nobody notices until the floor does.
PlumbingLine 3 · Electrical
Electrical service on the components that keep a house running, from the disconnect beside the condenser to the control wiring inside the cabinet. Test first, then trace the circuit, then repair the part that failed.
Electrical
Line 4 · Gas
Gas service and gas components: lines to furnaces and water heaters, shutoffs and appliance hookups, every fitting connected and checked before the crew leaves the house.
Gas01
A fresh filter catches dust without choking the return. The blower moves the air it was sized for and the coil sees steady airflow.
02
As the dust layer builds, airflow drops. The system runs longer to reach the same temperature, and you pay for the extra run time on the power bill.
03
A filter packed with dust starves the system. Cooling and heating both suffer, and the parts working hardest are the ones that fail first. Swap it before it gets here.
Open panel
These are Master Mechanical's own photos from the job, not stock. New builds like this lot get their systems planned before the walls go up; older homes get the panel opened and the readings taken before anything is replaced.
New install
Set beside a new brick build with the ductwork staged on top. The pad, the drain and the line set all go in before the unit is tied to the house.
Service call
Blue on the low side, red on the high side, a clamp meter on the compressor wiring. Nothing gets replaced on this unit until the readings say what failed.
Electrical
Contactor, capacitor and the wiring to them, tested in the open cabinet before anything is swapped, so the fix is the part that failed and not a guess.
Before you call
Straight answers on what we cover, where we work and the two habits that keep an outdoor unit healthy. Anything else, the phone is quicker.

No cooling, no hot water, a breaker that will not stay on or a gas appliance to hook up. Call or send a note and Master Mechanical will get back to you to set a time. Every job is priced once we know what the system needs.
