Melissa's history runs a lot longer than its skyline suggests. The town was platted in 1872 when the Houston and Texas Central Railroad came through, taking its name from either Melissa Quinlan or Melissa Huntington depending on which account you believe. On April 13, 1921, a tornado tore through and killed 13 people, destroying most of the young town — only a handful of structures survived, including the old bank building on Cooper Street and the Barker House. Melissa spent the next several decades as a small farm town, with the population bottoming out at just 285 residents in 1949.
That history makes the last few years look almost unrelated. The 2020 Census counted 14,339 people; by 2026 the estimate is closer to 32,900, a growth rate near 9–10% a year that makes Melissa one of the fastest-growing cities in North Texas. The practical result for homeowners: outside of the tiny historic core around Cooper Street, most of Melissa is brand-new construction, and most central air systems in the city are only a few years old. That newness helps, but it isn't immunity — builder-grade equipment and a rushed install during a construction boom still fail, and weeks of 95–105°F highs from July through September put real stress on even a two- or three-year-old system. This page lays out what those repairs typically cost in the DFW market, and when replacement — rare as it is in a city this new — actually makes more sense than fixing what's there.
Typical Dallas-Fort Worth market ranges. Your exact price comes from the $59 diagnostic — no guessing, no upsell.
The single most common no-cool call, and new construction doesn't skip it — a small cylindrical part that loses its charge in the heat and stops the compressor or fan motor from starting. Fast, inexpensive fix.
The relay that switches the outdoor unit on; even a two- or three-year-old system can develop pitted, arcing contacts after one full summer of cycling on and off in triple-digit heat.
Warm air with ice on the line set usually means a leak rather than a simple top-off. On a newer Melissa build this is sometimes an installation or factory defect, worth checking against any warranty still in force.
Little or no air moves from the vents even though the outdoor unit is running — the indoor blower motor or its control module has failed and needs to be replaced.
The most expensive single-component repair. It's uncommon on equipment this young, but when it happens on a system that's still within its manufacturer parts warranty, get that checked before paying out of pocket.
Given how new most of Melissa's housing stock is, repair is almost always the right call here — a two-to-eight-year-old system with a bad capacitor, contactor, or even a refrigerant leak is well worth fixing, and parts may still be covered under the manufacturer's warranty that came with the home. The exception is the small pocket of older homes in Melissa's historic core near Cooper Street; if you're in one of those and running original or much-older equipment, the usual rule applies — once a system passes 15 years old and needs a major repair like a compressor or coil, get a side-by-side repair-versus-replace quote before committing. For the large majority of Melissa homeowners in newer subdivisions, though, a weak part is just a repair, not a reason to replace the whole system.

For the large majority of Melissa homes, built in just the last few years amid the city's rapid growth, repair is almost always the smarter call — the equipment is too new to be worth replacing over one bad part. The exception is the small number of older homes in Melissa's historic core, where a system running past 15 years old with a major failure like a compressor is worth comparing against replacement costs.
Like the rest of North Texas, Melissa sees stretches of 95–105°F highs from July through September, and air conditioners run nearly nonstop for weeks at a time. Even a brand-new system can fall behind if it's slightly low on refrigerant or has a marginal part, because there's no cooler overnight stretch to let it catch up. A system that seemed fine in May can start losing the fight by August.
