Water pooling around the indoor unit or ceiling stains

Heating and air conditioning service built around Katy
Serving Katy and the wider Harris 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.
A large share of the equipment we service in Katy was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
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.

Katy77493 HVAC questions, answered
What brands do you service in Katy?
All of them. Our 77493 technicians are trained on York, Carrier, Daikin, Trane 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.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Katy, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
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 service commercial and light commercial properties?
Yes. Around Katy 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.
How much does an HVAC service call cost in 77493?
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.
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.
