April through October, the AC doesn't stop
Your AC runs about seven months a year here, not just a few weeks in summer. That's most of the year asking the compressor and the fan motor to keep up.

93 degrees, afternoon after afternoon
June through August, the afternoon high averages 93°F in Fort Bend County. A system working against that heat day after day wears down faster than one that gets real breaks.

- the average summer afternoon it cools against
- 33 hail events
- in ten years, and hail bends the fins on outdoor coils
- 39 wind events

NOAA nClimDiv, 1991–2020 normals
Half the homes in Fort Bend County were built in 2005 or later.
If your AC came with a newer house here, it's likely still within its working life, and a repair is probably the right call.
March is when to catch what seven months of cooling will find
Texas electricity ran 14.94 cents per kilowatthour in 2024. A struggling AC doesn't just cool worse, it pulls more power to do it. A weak capacitor makes the compressor work harder to start. A low refrigerant charge makes the whole system run longer to hit the temperature you set. Either way you're paying more for less cooling, every month this runs. Here, that's most months.
Get it diagnosed properly
Your air conditioner works hard here, and that's usually what's behind the problem. Have it diagnosed properly so the fix lasts.

What seven months of running finds first
A technician checking the system can look at the capacitor and the refrigerant charge before the heat sets in for the year. Those are the parts that strain first under long, hot run times. A capacitor that's gone weak will keep struggling to start the compressor, and a low charge will keep the system running longer than it should to hit the temperature you set. Found in April, either one is a straightforward repair. Found in August, with the afternoon high sitting near 93 degrees, it's the same repair after the system has already stopped keeping up.
The capacitor goes first, usually
The capacitor holds the charge that kicks the compressor and the fan motor into motion. That part takes a jolt every time the system starts, and over time it loses its ability to hold that charge. A weak capacitor shows up as a unit that hums, clicks, or tries to start and can't. It's one of the more common reasons an AC quits outright.
Low refrigerant means a leak, not a top-off
Refrigerant doesn't get used up the way fuel does. If the charge is low, it's because it's leaking out somewhere in the coil or the line set. Adding refrigerant without finding the leak just means doing it again later. A technician who checks the charge should be checking for the leak too, not just refilling it.
A new air conditioner would cut about $80 a year off cooling for a typical Fort Bend County home.
Estimates for a typical Fort Bend County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Texas fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Age matters less than what's actually failing. A capacitor or a contactor is a small, contained part. It fails on its own, it gets swapped, and the rest of the system doesn't care how old it is. A compressor is different. If that's what's going, it's the heart of the system, and replacing it alone often costs close to a new unit while leaving an old coil and an old fan motor to fail next. The other thing worth asking is how often a tech has had to come out for this same system. One repair is just a repair. A pattern of them is the system telling you it's done being patched. A tech who's honest with you will say plainly which kind of problem you've got, not just quote you a fix.
