956 Multi Service covers North Alamo for mobile home AC, heat pumps, heating repair and maintenance, a drive of roughly 65 minutes east of our Rio Grande City base. This unincorporated community just north of Alamo counted 3,722 residents at the 2020 Census on only 1.8 square miles. Its population swells each fall, because the Alamo area markets itself as a destination for winter Texans and is ringed with RV and mobile home resorts. That seasonal rhythm means systems here work in two directions: heat pumps warm park models on chilly winter nights, then the same equipment fights 100-degree afternoons after most visitors have gone home.
Park models, mobile homes and seasonal use above Alamo
The housing here leans heavily on manufactured homes, park models and compact single-story houses. Small homes use small equipment, often packaged units or ductless systems sized for a few hundred square feet, and replacement parts have to match.
Use patterns matter as much as size. The 2020 Census found nearly 15 percent of North Alamo's housing units vacant, a count taken in April when many seasonal residents had already left. About 11.7 percent of residents were 65 or older.

Homes that sit closed for months build up humidity if the AC is turned off. Drain lines dry out or fill with debris, and wasps or ants move into quiet outdoor units. When owners return in the fall and switch on the heat, problems that started during the summer show up all at once.
Cold snaps add their own pressure. Winter Storm Uri in February 2021 showed how hard a freeze can hit Valley heat pumps and heat strips that were not ready.
Heating and cooling services for North Alamo homes
The work we do here follows the winter-visitor calendar:

Mobile Home AC in North Alamo

Heat Pumps in North Alamo
Heat pumps carry many North Alamo homes through the winter-visitor months and then the long cooling season, so one machine logs heavy hours in both modes nearly year-round.

Alamo Road, PSJA territory and the winter-visitor corridor
North Alamo lies along the Alamo Road corridor, which is Farm to Market Road 907, the main north-south route into Alamo. To the west is San Juan, and the area falls within Pharr-San Juan-Alamo ISD. This part of Hidalgo County is where the Valley's winter-Texan season is most visible.
It is not only a seasonal place, though. The 2020 Census put North Alamo's median age at 29.8, and half of its 999 households had children under 18. Sgt. Leonel Trevino Elementary sits inside the CDP, and students go on to Audie Murphy Middle School and PSJA Memorial High School. Those year-round families need the AC most from May to October, exactly when the winter visitors are gone, so our calendar here stays busy in both seasons.

Between North Alamo and our Rio Grande City base
From North Alamo, take Alamo Road (FM 907) south to I-2/US 83 at Alamo, then drive west on US-83 through Pharr, McAllen, Mission and La Joya to Rio Grande City.
Typical drive: about 1 hr 5 min (53 mi)
Get DirectionsCan we service a home while the owner is out of state?
Usually, if access is arranged ahead of time. Plenty of North Alamo owners are away when a unit needs attention, so let us know which neighbor, relative or park office can open the home. Tell us any park rules about work hours, parking or where trucks may stop. We describe what we found by phone and talk through options before replacing anything.

For a bigger purchase such as a new heat pump, ask about financing; cash and Visa, MasterCard, Amex or Discover also work.
What winter Texans in North Alamo ask before the season starts?
When should we have our park model unit checked before arriving for the winter?
Early fall is best, before the busy season starts and before you need heat on the first cool night. If you are arriving from out of state, a neighbor or park office can let us in, and we can check the heat pump in both heating and cooling modes so you arrive to a working system. Our drive to North Alamo runs a little over an hour, so booking in September or early October gives the best choice of dates.
Our heat pump blows cool air on cold mornings. Is it broken?
Not necessarily. On cold, damp mornings a heat pump goes into defrost and can blow cooler air for a few minutes. If it never warms up, the backup heat strips may have failed, or the reversing valve or a sensor may be stuck. A technician can test each part and tell you which one it is. During the February 2021 freeze, NWS Brownsville recorded hard-freeze conditions of 27°F or lower for 12 to 24 hours across the Lower Valley, which is when backup strips matter most.
How should we set the thermostat when we leave North Alamo for the summer?
Leave the system on rather than off. A cooling setpoint in the low 80s keeps humidity from building up inside the closed home, which protects cabinets, mattresses and paneling from mildew. Have the drain line checked before you leave so a clog does not overflow while no one is there. North Alamo's April 2020 census found nearly 15 percent of homes vacant, and seasonal homes like those often stay shut through the hottest months.
