Around Round Rock, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Because Texas runs high-capacity split air conditioning with gas or electric heat, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

Round Rock78682 HVAC questions, answered
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 Round Rock 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.
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.
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.
How much does an HVAC service call cost in 78682?
A diagnostic visit in Round Rock 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.
What brands do you service in Round Rock?
All of them. Our 78682 technicians are trained on American Standard, Trane, Heil, Daikin and essentially every other residential brand sold in Texas, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Round Rock 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.
