AC Maintenance in San Marcos

What Our 16-Point AC Inspection Covers

A tune-up is only as useful as its checklist. Here’s exactly what our technicians inspect during a standard $159 visit:

The 16-point tune-up checklist:

• Check thermostat operation
• Clean or replace filter (customer-supplied filter)
• Check system temperature split
• Inspect disconnect
• Inspect fuses
• Inspect wiring
• Tighten electrical connections
• Inspect contactors, relays, and pressure controls
• Inspect electrical safety circuits
• Check voltage and amperage to all motors
• Inspect indoor blower and motor for dirt buildup
• Inspect bearings and lubricate all moving parts if needed
• Inspect condensate drain
• Inspect outdoor coil
• Inspect duct seal at unit and secure panels
• Run and test system

At the end of the inspection, your technician walks you through every finding and any recommendations for improvement. The standard tune-up doesn’t include drain clearing or condenser washing, and inspections for other system types may vary.

San Marcos sits in the limestone belt of Central Texas, and water drawn from the Edwards Aquifer carries high mineral content that accumulates on evaporator coil surfaces and inside condensate drain lines over a cooling season. Left unchecked, that buildup restricts airflow and raises the risk of drain backups. Catching it during a tune-up can cost less than dealing with a clogged drain or diminished AC repair capacity in the middle of July. Checking voltage and amperage to all motors flags electrical stress early, before it shortens compressor or fan motor life.

Why Regular Maintenance Pays Off in Central Texas

A San Marcos cooling season can stretch six months or longer. Systems that haven’t been serviced work harder to hit target temperatures, and that extra strain compounds over time. Annual preventive HVAC maintenance helps systems operate efficiently, which can reduce monthly energy costs and support longer system life.

Consistent maintenance also helps keep dehumidification effective during the humid stretches of summer, a factor that matters as much as temperature in this climate. Beyond comfort, most manufacturers require documented professional maintenance to keep warranty coverage valid. Skipping tune-ups can void that protection entirely, turning a covered repair into an out-of-pocket expense.
