HVAC service in San Marcos, TX, and surrounding areas

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.
A mix of smaller older homes and standard suburban attic systems. Some rentals have been ‘repaired’ with the cheapest available part.
San Marcos is hot and noticeably humid. Winters are mild, with occasional freezes that still shut down neglected heat.
