Heating and air conditioning service built around Llano

Most of the work we do in Llano starts the same way: the system is running but the house is not comfortable. Before we replace anything, we measure airflow, static pressure and temperatures so you are paying for the actual fault.

Because Texas swings between seasons quickly, a lot of our Llano calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.

Local equipment profile:Texas homes are most often served by high-capacity split air conditioning with gas or electric heat. Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm.

If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Llano78643 HVAC questions, answered

How quickly can a technician get to Llano?

For the 78643 service area our target response time is 60-90 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.

Do you offer maintenance plans?

We do. A two-visit plan in Texas covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.

Is my system low on refrigerant, or is it leaking?

Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.

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.

Why is my system short cycling?

Short cycling in Llano most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.

How often should I change my filter in 78643?

Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Llano 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.
