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.
Homes in Harris County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
Peak cooling demand here runs March through November. Booking a tune-up in early spring means you are not competing with the whole neighbourhood for a tech in July.

Katy77492 HVAC questions, answered
How much does an HVAC service call cost in 77492?
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 does a new system cost in Katy?
A complete residential replacement in the 77492 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
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.
Are your technicians licensed and insured?
Every technician dispatched into Katy 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 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.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Katy 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.
