Preventive HVAC maintenance in Austin, TX.

Equipment in Central Texas runs roughly seven months of cooling, much of it near full load, plus a short heating season. That is an enormous number of run hours compared with most of the country, and it means small problems have a lot of time to become large ones. A capacitor drifting out of tolerance, a condenser coil packed with cottonwood and oak pollen, a drain line half-closed with scale from hard water, a contactor with pitted points — none of those stop the system in April. All of them stop it in July.

The maintenance visit is $300 per system, and that is a real, published, flat price for a comprehensive service. To be clear about what the number buys: it is one visit. Not a year of visits, not a plan you join, not a subscription that renews — one comprehensive service on one system, booked when you want it. If the house has two systems, and most two-story Central Texas homes do, it is two visits' worth of work and it is priced as two.

The visit covers the things that actually predict failures rather than a filter change and a sticker: the outdoor unit cleaned, the drain lines cleaned, and the compressor, the fan motors, the blower motors, the capacitor, the contactor and the refrigerant levels all checked. Those are the parts that quietly drift out of spec through the spring and then take the system down on the first genuinely brutal week of the summer.

There is a second thing maintenance buys you, which is information. A system that gets looked at regularly tells you when it is approaching the end honestly, rather than announcing it during a heat advisory. Knowing in March that a compressor is drawing high amps and a coil has been leaking slowly is what lets you plan a replacement instead of making a decision in a hot house with a technician standing in your hallway.
