Heating and air conditioning service built around Round Mountain
We treat 78663 as a dedicated service zone. Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm. Because the equipment here works hard for a long season, we lean heavily on catch-it-early diagnostics rather than emergency replacements.
Homes in Blanco County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
The busiest week of our year in Round Mountain is the first stretch of sustained march weather. Systems that idled all season fail in clusters.

Round Mountain78663 HVAC questions, answered
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Texas, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Round Mountain see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
How much does an HVAC service call cost in 78663?
A diagnostic visit in Round Mountain typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
How often should I change my filter in 78663?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Round Mountain with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Do you service commercial and light commercial properties?
Yes. Around Round Mountain we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
