The Katy77491 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.
Thermostat reading several degrees off from reality
Heat pump stuck blowing cold air in heating mode
Refrigerant leak at a flare or coil connection
Outdoor condenser humming but the fan not turning
Skyrocketing utility bills with no change in usage
Dead or bulging run capacitor on the condenser
Heating and air conditioning service built around Katy
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
Local homeowners often run their system harder than the design intended, especially during March through November. That accelerates wear on contactors, capacitors and blower bearings.
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.

Katy77491 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.
How often should I change my filter in 77491?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Katy with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
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.
How quickly can a technician get to Katy?
For the 77491 service area our target response time is 90-120 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
What does a new system cost in Katy?
A complete residential replacement in the 77491 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.
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.
