If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Pilot light or hot surface igniter failing repeatedly

Dead or bulging run capacitor on the condenser
No cool air, or air that is barely cooler than the room
Frozen evaporator coil or ice on the refrigerant lines
Heating and air conditioning service built around Katy
If your high-capacity split air conditioning with gas or electric heat has started short cycling, blowing warm air or making a noise it never used to make, you are not alone — Katy generates some of the highest call volume we handle in Texas. Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm.
Because Texas swings between seasons quickly, a lot of our Katy 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.
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.

Katy77494 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.
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.
What brands do you service in Katy?
All of them. Our 77494 technicians are trained on Rheem, Mitsubishi Electric, York, Amana 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.
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 Katy 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 much does an HVAC service call cost in 77494?
A diagnostic visit in Katy 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.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Texas is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
