Heating and air conditioning service built around Walburg
Serving Walburg and the wider Williamson County area, our crews carry the common failure parts on the truck — capacitors, contactors, igniters, flame sensors, motors and filters — so the first visit is usually the last one.
Local homeowners often run their system harder than the design intended, especially during March through November. That accelerates wear on contactors, capacitors and blower bearings.
We recommend two maintenance visits a year in Texas: one before March through November and one before December through February. It is the single highest-return thing a homeowner can do for equipment life.

Walburg78673 HVAC questions, answered
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.
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.
Are your technicians licensed and insured?
Every technician dispatched into Walburg is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Walburg we see algae and dust clogging drain lines constantly during March through November. It is a fast fix but ignoring it ends in ceiling damage.
How often should I change my filter in 78673?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Walburg 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.
Why is my system short cycling?
Short cycling in Walburg 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.
