Commercial HVAC
Repair It Guys diagnoses and repairs commercial split system heating and cooling equipment — indoor air handlers, outdoor condensing units, refrigerant lines, electrical and controls — throughout Tyler, Longview and East Texas.
Commercial Split System Repair
A commercial split system splits the work between an outdoor condensing unit and an indoor air handler — a problem with either one, or the line set connecting them, can affect the whole system.
We inspect and test the outdoor unit, the indoor unit, the refrigerant line set and the electrical and control components before recommending a repair.

Split system diagnosis and repair.
What You're Noticing
Air moving but not reaching the right temperature can involve the outdoor condensing unit, the refrigerant charge, the indoor coil, or the controls between them — testing identifies which one is actually responsible.
A condensing unit that won't start can involve an electrical fault, a failed capacitor or contactor, a control-circuit issue, or a safety switch that's shut it down — testing determines which one it actually is.
Reduced airflow at the indoor unit can involve the blower, a restricted coil or filter, or ductwork connected to the system — inspection determines which component is actually restricting it.
Water at or near an indoor air handler can involve the condensate drain, the drain pan, a clogged or disconnected drain line, or other factors depending on the installation — inspection determines the actual source rather than assuming which one it is.
A system that cycles too often or never seems to catch up can involve refrigerant charge, airflow, thermostat operation, or a control problem — testing narrows down which.
Noise or vibration from either the indoor or outdoor unit, or an unusual odor when the system runs, is worth having inspected before it develops into a larger failure.
What We Check
A split system failure can originate at the outdoor unit, the indoor unit, the line set connecting them, or the electrical and control components. We test the relevant systems to find the actual cause rather than guessing at parts.
Compressor, condenser fan motor, capacitors, contactors and refrigerant-side components on the outdoor unit.
Blower operation, evaporator coil condition, airflow and the condensate drain system.
The line set connecting the indoor and outdoor units, including leak points and insulation condition.
Wiring, disconnects, thermostats and control boards — components and layout vary by manufacturer and model.

Frequently Asked Questions
Straightforward answers for business owners and facility managers.
A split system separates the equipment into an outdoor condensing unit and an indoor air handler connected by a refrigerant line set, as opposed to a rooftop unit that houses everything in one cabinet. Many businesses run one or several split systems serving different areas.
Rooftop Unit / RTU RepairThat can involve the outdoor unit's electrical components, a failed capacitor or contactor, a tripped safety control, or a control-circuit signal that isn't reaching it. We test the relevant components to identify the actual cause.
It's worth having looked at promptly, since standing or leaking water can cause property damage the longer it continues. The condensate drain, the drain pan and other components can all be involved — inspection determines the actual cause rather than assuming which one it is.
Yes. Many commercial buildings run multiple split systems or zones — we can inspect and service more than one unit or system in a single visit.
Equipment architecture and components vary by manufacturer and model. We evaluate the specific unit on site and diagnose it on its own terms rather than assuming a generic layout.
