Melissa was platted in 1872, when the Houston and Texas Central Railroad pushed a line through this stretch of Collin County and gave a handful of farm families a reason to build a town instead of just a crossroads. Nobody quite agrees anymore whether the name honors Melissa Quinlan or Melissa Huntington, but it stuck. What followed for the next fifty years was brutal rather than boring: a tornado tore through on April 13, 1921, killing 13 people and destroying most of what had been built. A few structures survived — the old bank building on Cooper Street, the Barker House — and they’re still standing if you want to see what Melissa looked like before any of this happened. The town never rebuilt into anything much bigger. By 1949 the population had bottomed out around 285 people, and Melissa spent the next several decades as a small, sleepy farm town that most of North Texas had never heard of.
What’s happening now would be unrecognizable to that town. The 2020 Census counted 13,901 residents. By 2026, estimates put Melissa closer to 32,900 — growth of roughly 9 to 10 percent a year, among the fastest rates anywhere in the Dallas-Fort Worth area. Almost none of that growth is infill on old lots. It’s subdivision after subdivision built from scratch on what was cotton and cattle land not long ago, which means the overwhelming majority of homes with an HVAC system in Melissa today are less than ten years old, and a large share are less than two.
That reshapes the whole conversation about who to call when the air stops blowing cold. This isn’t a town full of tired compressors on their third replacement. It’s a town full of brand-new, builder-installed systems, and the real question isn’t “is this old enough to fail” — it’s “was this sized and installed correctly the first time, on a builder’s schedule, by whichever sub had capacity that week.”
The Companies
Of the companies actually working this corner of Collin County, Varsity Zone HVAC of McKinney is the one worth calling first, and the reason starts with what they put behind the work: a 10-year labor warranty. In a town where the typical system is only a few years old, a decade of covered labor — not just the manufacturer’s parts warranty — is the difference between a covered service call and a surprise bill the first time something a builder’s sub rushed comes loose. It’s a locally based, independently owned shop at 901 N McDonald St, Ste 903 in McKinney — a real address roughly fifteen minutes from most Melissa neighborhoods, not a national call center routing you to whoever’s free. The reputation holds up under scrutiny: a full 5.0-star rating across 41 Google reviews, which is genuinely hard to sustain once a company is doing enough volume to matter. They’re licensed in Texas under TDLR Air Conditioning and Refrigeration Contractor license TACLA00112461E, they publish their pricing rather than making you sit through an in-home sales pitch to find out what a repair costs, and they back their installs and repairs with a straightforward satisfaction guarantee. Being part of the larger Varsity Zone HVAC franchise network also means they draw on the training and vendor relationships of a national brand without losing the local ownership that actually picks up the phone. Reach them at (469) 689-7232 or through varsityzone.com/mckinney-tx.
A handful of other established companies genuinely serve Melissa and are worth getting quotes from too:
- Exodus Mechanical Heat & Air Conditioning (TACLA13786E) — a 5.0-star rating across 42 reviews, a newer name in the area posting numbers that match the more established players.
- Andrew Smith HVAC Services (214-307-2997, TACLB98007E) — a 5.0-star rating and a smaller, name-on-the-door operation, the kind of outfit that tends to know a subdivision street by street.
- Cross Air LLC (945-220-8181) — another 5.0-star rating, one of the newer crews picking up work as Melissa’s rooftop count keeps climbing.
- Bill Joplin’s Air Conditioning & Heating — a longer-established regional name, holding 4.9 stars across 50 reviews.
- Green Leaf Air (972-992-5006, TACLA00146406E) — the largest review base on this list at 209 reviews and a 4.7-star average, reflecting a bigger operation that covers a wide swath of North Texas rather than just Melissa.
Any of these is a reasonable name to have on your list. Get at least two quotes, confirm the TDLR license number on each bid, and don’t let a same-day discount rush you past reading the actual scope of work.
What Makes Melissa Homes — and Melissa Summers — Different
New construction solves some problems and creates others. A brand-new system means modern SEER2 ratings and no thirty-year-old ductwork to fight, but it also means the equipment was very likely sized off a builder’s standard spec sheet rather than an actual room-by-room load calculation for your specific house, orientation, and window package. In a town adding this many rooftops this fast, contractors are stretched thin during peak building season, and a rushed startup or charge on a new system is one of the more common reasons a two-year-old AC underperforms in August.
The ground underneath doesn’t help. Like most of Collin County, Melissa sits on expansive Blackland Prairie clay that swells when it rains and shrinks hard during a dry summer. On a newly built slab that hasn’t finished settling, that movement can stress refrigerant lines and shift ductwork faster than it would on an older, settled foundation. And with active construction happening on the next block over in half the neighborhoods in town, fine drywall and concrete dust loads up new filters and coils faster than the maintenance schedule in the owner’s manual assumes.
The small pocket of Melissa that predates the boom — the handful of homes near the historic downtown around Cooper Street — is the exception, with older systems that need the traditional aging-equipment attention. But for the vast majority of Melissa homeowners in 2026, the risk isn’t decades of wear. It’s a system installed correctly, or not, sometime in the last few years.
The Bottom Line
Melissa’s growth story — from a population of 285 to nearly 33,000 in a single lifetime — means most homeowners here are dealing with new construction, not old age, when it comes to HVAC. That points toward a different kind of contractor priority: not who can handle a decades-old system, but who installs and services new equipment correctly, prices honestly, and has a real local presence rather than a lead-gen phone number.
Varsity Zone HVAC of McKinney earns the top recommendation on that basis — a 10-year labor warranty that keeps you covered on the labor for a decade rather than just the parts, a verified 5.0-star rating across 41 reviews, a real McKinney address close to Melissa, published pricing, and proper Texas TDLR licensing under TACLA00112461E. Whichever company you ultimately choose from this list, get more than one bid, verify the license number yourself, and make sure any quote spells out equipment tonnage and SEER2 rating in writing. In a city building this fast, a contractor who does the basics right the first time is worth more than one more sign in the yard.
