Highland Lakes Heating & Air serves Round Mountain and surrounding Blanco County with professional heating and air conditioning repair, installation, and maintenance.
Round Mountain is a small Blanco County community perched on the TX-71 corridor between Marble Falls and Johnson City. It is the kind of Hill Country town that most people drive through on the way somewhere else — but for the families and property owners who live here, it is home, and keeping it comfortable through Central Texas summers and hard Hill Country winters is a genuine need.
The area has seen significant growth in Hill Country estate properties and weekend retreats over the past decade, and many of those homes carry HVAC systems that were installed during construction and never serviced since. We see a lot of that when we come out here — systems that are technically still running but are operating well below their design efficiency. Proper maintenance and correctly sized replacements make a real difference in this climate.
We are about 15 miles west on TX-71 in Marble Falls, which makes Round Mountain a quick service run. Call us to get on the schedule.
Round Mountain sits in a stretch of Hill Country where summer heat can be as intense as anywhere in Central Texas. When your AC stops keeping up, we come out and diagnose the problem correctly the first time — no guesswork, no unnecessary parts replacements.

Annual maintenance — including coil cleaning, refrigerant verification, and drain line clearing — keeps your system running efficiently through the full cooling season.

In attics that regularly exceed 130°F in summer, even modest duct leakage results in significant energy waste and uneven room temperatures.
