The Katy77450 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.

Water pooling around the indoor unit or ceiling stains
Furnace lights then shuts down after a few seconds
Thermostat reading several degrees off from reality
Heat pump stuck blowing cold air in heating mode
Heating and air conditioning service built around Katy
Homeowners across Katy call us when the system simply will not keep up. Extended extreme heat, attic temperatures well above 140 degrees, and grid stress during heat waves are the norm. That is why we staff a live dispatch line around the clock instead of routing you to a queue.
In the 77450 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
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.

Katy77450 HVAC questions, answered
What does a new system cost in Katy?
A complete residential replacement in the 77450 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.
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.
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.
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.
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.
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.
