Mission Air Conditioning urges RGV homeowners to book fall AC tune-ups

Mission Air Conditioning is encouraging Rio Grande Valley homeowners to schedule fall HVAC service now, arguing that the region’s mild winters do not create the usual cold-weather reminder for maintenance. The company says early tune-ups can catch worn parts, improve efficiency and prepare systems before winter and the next summer heat arrive.

Why it matters: - Rio Grande Valley homes often skip fall HVAC maintenance because the region rarely gets a freeze to trigger it. - Mission Air Conditioning says a fall tune-up can catch worn parts before they fail, help control energy costs and extend equipment life. - The timing matters in South Texas, where air conditioners stay in use far longer than in colder climates.

What happened: - Mission Air Conditioning urged homeowners in McAllen, Edinburg, Mission and the wider Rio Grande Valley to schedule a fall AC tune-up. - The company issued the reminder as the peak cooling season winds down and winter approaches. - The company also pointed homeowners to its guide on how often RGV households should service their AC. - Homeowners can schedule a fall tune-up or ask about the Mission Care Plan through Mission Air Conditioning’s website.

The details: - ENERGY STAR’s maintenance checklist calls for a spring checkup for cooling systems and a fall checkup for heating systems. - In colder regions, the first frost often prompts homeowners to book that second service visit. - McAllen rarely gets that cue. - NOAA’s 1991 to 2020 climate normals show McAllen Miller International Airport averages fewer than one night a year at or below freezing. - Chicago O’Hare International Airport averages about 121 freezing nights a year over the same period. - McAllen averages 4,989 cooling degree days a year and 453 heating degree days. - McAllen’s normal daily high in October is still 89 degrees. - Jose Zavala, owner of Mission Air Conditioning, said fall is the best time to find a worn part before the system has to handle another summer. - McAllen’s normal daily highs run from about 97 to nearly 100 degrees from June through August. - Those three months are also when the city’s cooling demand peaks in the NOAA normals. - ENERGY STAR says dirty coils force a system to run longer, which raises energy costs and shortens equipment life. - ENERGY STAR also says airflow problems can cut a system’s efficiency by up to 15 percent. - Mission Air Conditioning’s Mission Care Plan includes two tune-ups a year, priority service and 10 percent off repairs.

Between the lines: - The message is less about seasonal tradition and more about local climate reality. - In the Rio Grande Valley, AC maintenance is still the urgent service item even as the calendar turns toward winter. - A scheduled fall visit also gives homeowners a chance to check heating equipment before the Valley’s limited cold nights arrive.

What's next: - Mission Air Conditioning is steering homeowners toward a fall service window rather than waiting for a cold snap that may not come. - The company is also using the reminder to promote its recurring maintenance plan for households that want routine service built in. - More information is available through Mission Air Conditioning’s website and the company’s Facebook page.

The bottom line: - In the Rio Grande Valley, the best cue for HVAC maintenance is not the first freeze. It is the end of peak cooling season.
