Light commercial work in San Marcos is usually storefronts, offices, and small buildings, not central plants. Humidity near the river corridor makes moisture control as important as the thermostat number.
San Marcos has campus rentals, older houses, and newer subdivisions on the edges. River-corridor humidity means an oversized system can hit the setpoint and still leave the house damp. Rentals add deferred maintenance: filters, drains, and contactors that should have been replaced a year ago.
Commercial HVAC issues we see in San Marcos
Systems that cool the thermostat and leave the air damp
Short-cycling equipment does not dehumidify. In San Marcos that feels like a failed air conditioner even when the supply air is cold.
Rental equipment with no maintenance record
We write down what we find: failed parts, unsafe heat exchangers, and simple neglect. Owners can act on a list.
Drain and closet problems in smaller homes
Air handlers in closets overflow into the house when the trap is wrong. That is a common San Marcos call after a heavy cooling week.
