Starr County is where we live and work. Our shop is in Rio Grande City, the county seat, so HVAC calls in Starr County are local trips for us: roughly 5 to 35 minutes to most homes in the southern half of the county, longer for ranch properties up north. The county covers about 1,229 square miles of Rio Grande Plain brush country, and the homes spread across it are a real mix. Historic masonry in Roma, block houses that families have expanded over years, manufactured homes in the colonias, and ranch houses at the end of caliche roads all need cooling that copes with long, dry, very hot summers.
From the river towns to the ranch roads: how we cover the county
Most of the county's people live along US-83, the highway that follows the Rio Grande across the southern edge. Starr has four incorporated cities: Rio Grande City in the middle, Roma and Escobares to the west, and La Grulla toward the Hidalgo County line. Between them sit dozens of small communities, many of them census-designated places rather than towns.
We plan routes along that corridor. A morning might start east of the city in Las Lomas, Garza-Salinas II or La Puerta, then move out to Mikes, East Alto Bonito and West Alto Bonito above La Grulla. Western runs follow US-83 past Garceño toward Roma, and sometimes on to Salineño and Falcon Heights near Falcon Dam, finished in 1954.
North of the highway the county opens into ranch country. FM 755 climbs from Rio Grande City toward Santa Catarina and La Gloria, and FM 649 leaves US-83 about eight miles west of the city and heads toward Jim Hogg County. We go up both, but distances there are real, so we book those visits with a clear time window instead of squeezing them between town calls.
Colonias, block additions and 116°F records: what local housing asks of an AC
Heat is the headline. The Handbook of Texas puts the county's average July maximum near 99°F, and Rio Grande City's all-time record is 116°F. Rain averages only about 22 inches a year, so dust settles on outdoor coils for weeks between showers. Condensers here simply work harder than they would somewhere milder.
Housing adds the second layer. The Texas Secretary of State counted 256 colonias in Starr County in 2014, and many homes in them are manufactured units or owner-built block houses. Those homes bring their own problems: package units on blocks, underfloor belly ducts that tear or drop loose, and additions with no duct runs at all. That is why so much of our county work is mobile home AC and ductless mini-splits, not only central systems.
Census estimates for 2024 count about 23,300 housing units in Starr County, roughly two in three owner-occupied, with a median build year around 1995. A house from that era may still have its original ductwork, and leaky joints in a hot attic can make a healthy system feel weak, so we check the ductwork before blaming the equipment.
Weather events matter too. Hurricane Hanna flooded parts of the county in July 2020, and Winter Storm Uri froze the Valley in February 2021. After flood water or a long outage, have equipment checked before running it hard.
Utility service in the area comes from more than one provider, including AEP Texas and Magic Valley Electric Cooperative, so outage and rebate details depend on your account.

Emergency AC Repair in Starr County
Hurricane Hanna's flooding in July 2020 and the February 2021 freeze both left county homes without working equipment, and with about 3.3 people per household here, one dead system puts several people at risk.

AC Coil Cleaning in Starr County
Only about 22 inches of rain falls here in an average year, so caliche dust and mesquite debris pack into outdoor coils for weeks between showers and quietly cut what a condenser can deliver.

AC Condenser Pads in Starr County
Caliche and clay ground across Starr County shifts after a hard rain, tilting condensers that sit on stacked blocks or bare soil; a level poured pad keeps the coil, line set and drain where they belong.

Is a long drive out of Rio Grande City a problem for service?
Usually not. Because we are based in the county seat, the drive to most of southern Starr is shorter than it would be from McAllen or Edinburg. Same-day repair happens often when the schedule allows, especially for homes along US-83.
For rural properties, a few details save time. Tell us the road name, any gate code or lock, whether there is a dog loose, and whether the outdoor unit is easy to reach. Knowing the symptom ahead of time also lets the technician load likely parts, such as a capacitor or contactor, and avoid a second trip.
On arrival we test before we quote: electrical readings at the outdoor unit, refrigerant pressures where it makes sense, airflow at the indoor coil, and the drain line. Simple fixes are often finished on that visit; when a part must be special-ordered, you hear about it before we leave. For a breakdown in dangerous heat, our emergency AC repair page explains what to do while you wait.


Falcon Dam to the Hidalgo line: landmarks along our county routes
Starr dates to 1848 and carries the name of James Harper Starr, a Republic of Texas treasury secretary; its oldest towns show that age. Roma's historic district, a National Historic Landmark District since 1993, holds brick and sandstone buildings that need a gentler approach than a new build. Rio Grande City links to Camargo by international bridge, and Roma links to Ciudad Miguel Alemán the same way, and shops near both crossings lean hard on their cooling.
At the western edge, Falcon State Park opened in 1965 beside the reservoir, and homes out that way mean a longer drive for us. To the east, US-83 carries on toward the Hidalgo County line, where our Hidalgo County service area picks up.

Between Starr County and our Rio Grande City base
US-83 runs the length of southern Starr County along the river, from the Falcon Dam area through Roma and Escobares to Rio Grande City and on toward La Grulla; from the north, FM 755 and FM 649 both come down to US-83.
Typical drive: Home base — ~5–35 min anywhere in southern Starr County

What do people across Starr County ask before booking?
Which parts of Starr County do you cover from Rio Grande City?
All of it. Most calls come from towns along US-83, from the Roma and Escobares side in the west to La Puerta, the Alto Bonito communities and La Grulla in the east, and those are usually 5 to 35 minutes from our base. We also drive up FM 755 and FM 649 to ranch homes in the north and out toward Falcon Heights; those trips take longer, so tell us your road and gate details when you call.
Do you work on AC in colonias and manufactured homes in Starr County?
Yes, it is a large share of our work in a county where the state counted 256 colonias in 2014. We repair and replace package units on manufactured homes, fix crushed or loose belly ducts, and install mini-splits in block homes that have grown one room at a time. If the home has no ductwork at all, ductless heads are often the simplest way to cool it without opening walls.
How do I check that an AC contractor in Starr County is properly licensed?
Texas requires air conditioning and refrigeration contractors to hold a licence from the Texas Department of Licensing and Regulation. Ask any contractor for the licence number, then look it up on the TDLR website before work starts. The rule is the same inside the city limits of Rio Grande City, Roma, Escobares and La Grulla and out in the unincorporated colonias, because the licence is a state requirement, not a city one. Anyone handling refrigerant also needs EPA Section 608 certification.
