AC & Heating Repair in Katy, TX

We actually know Katy

What working Katy every week teaches you

AC repair, furnace service and heat pump work across Katy — every truck dispatched from our Katy shop.

Getting to you

Our shop is on Avenue D in Katy. For most of the city that is a ten-minute drive, which is the whole reason we can answer an emergency call with a truck at the door inside an hour.

The housing stock

Three housing eras means three HVAC realities: original-town homes where ductwork was retrofitted into attics never designed for it, a 1970s–80s wave now on its second or third full system, and master-planned sections hitting first-replacement age street by street.

Heat & humidity

Cooling here is a seven-month season, and August is a humidity problem as much as a temperature one. A system sized on square footage alone short-cycles past the moisture — we size for the Gulf Coast load, latent heat included.

The local pattern

Heating & Air problems we see most in Katy

Capacitors that fail in the first 100-degree week

The single most common Katy AC failure, and it clusters. A capacitor that was marginal all spring gives up the first time the system runs a full day at design load — which is why the first real heat wave produces a week of no-cooling calls.

Frozen and fouled evaporator coils

Long runtimes plus a dirty filter plus low airflow ices the coil. The symptom people report is 'blowing warm', and the fix is not refrigerant — it is finding out why the airflow dropped in the first place.

Condensate drains backing up into the pan

Katy humidity means an air handler pulls a lot of water. A drain line that slimes over backs up into the secondary pan and trips the float switch, which shuts the system down — often the first sign is simply that the AC stopped, with no other symptom.

Twenty-five-year-old systems in the 1990s neighborhoods

The master-planned build-out installed thousands of systems in a narrow window. Those units are now at or past end of life together, and many still run R-22, where a refrigerant leak turns an ordinary repair into a replacement conversation.

Can you come out the same day for AC in Katy?

Usually yes. We dispatch from Avenue D in Katy and we run 24/7, so summer no-cooling calls inside Katy are typically same-day and often within a few hours.

My AC is blowing warm — is it low on refrigerant?

Sometimes, but a frozen or fouled evaporator coil produces the same symptom and is more common here. Refrigerant does not get used up; if a system is genuinely low, there is a leak, and adding more without finding it just buys a few months.

Do you service both the plumbing and the HVAC in the same house?

Yes — both trades are in-house under one company. That matters more than it sounds on shared problems like condensate drains and gas lines, where nobody gets to point at the other trade.
