Pull the service panel off a condenser sitting under mature oaks in 76034 and the first half of the problem is usually right there: a coil packed with leaf litter, seed pods and pollen mat, plus shrubs grown in tight enough that the unit breathes its own exhaust. The homeowner calls it a dying compressor. Often it is a healthy compressor working far too hard because the heat has nowhere to go.
I’m Anthony Marquez, and Air 4 North Texas has been mine since 2021. I’m based in North Richland Hills, so Colleyville is minutes away straight up TX-26. I do the work personally: the same person diagnoses your system, quotes it and comes back if anything needs a second look.
Text or call (817) 888-7998 whenever it quits — I pick up nights, weekends and holidays.
Rates, In Writing
Numbers first, because posting them is the fastest way to prove nobody is improvising a price in your driveway. Treat each as an estimate range, not a firm bid. The final figure moves with the age and brand of your equipment, refrigerant type, tonnage, and how hard the attic or outdoor unit is to reach.
| Work | Typical range |
|---|---|
| Diagnostic or service call | $89 – $125 (nights and holidays at the top) |
| Capacitor | $150 – $350 |
| Contactor | $325 – $475 |
| Refrigerant recharge | $200 – $600 |
| Blower motor | $800 – $4,200 (variable-speed ECM at the top) |
| Thermostat | $200 – $650 |
| Straight-cool system replacement, installed | $8,000 – $10,000 |
| Heat pump replacement, installed | $9,000 – $11,500 |
| 17–18 SEER2 high-efficiency system | $13,000 – $18,000 |
| Duct replacement | $6,500 – $18,000 |
Two things I hold to. I do not price a replacement on equipment I have not diagnosed first, and when a repair approaches half the cost of new, I show you that arithmetic and let you decide. Plenty of systems I look at here should be repaired and kept, and I say so.
What the Tree Canopy Does to Your Equipment
The housing insight that matters here: these lots are wide, the shade is old, and plenty of the custom homes from the eighties and nineties still move air through duct laid out for whatever unit the original builder installed. That combination produces a specific set of calls.
Coils that cannot shed heat. Heavy canopy cuts your cooling load, which is genuinely good, then drops debris into the condenser all fall. A washed coil and real clearance around the cabinet recovers capacity you already paid for. Roots and thickening landscape beds crowd units that had room fifteen years ago.
Original duct in a remodeled house. Kitchens get opened up, walls come down, rooms get added, and the distribution system never gets revisited. A modern high-static air handler then inherits a return path built for something gentler, and the far bedrooms starve.
Age gaps between systems. In two- and three-system homes here it is normal to find one unit a decade newer than another. They will never behave identically, and I would rather tell you which one to plan around than sell you both.
Shaded roofs, humid interiors. A house that sheds solar gain but carries oversized equipment short-cycles, never dehumidifies, and feels clammy at 73 degrees.
Condensate problems. Tree-covered lots hold moisture, so clogged drains, algae and rusted pans turn up more here than in the unshaded subdivisions west of town.

Streets, Parks and Neighborhoods on My Route
Colleyville is 76034. Subdivisions I get into regularly include Tanglewood, Castleton Manor, Bridlewood Estates, Brook Meadows, Caldwell’s Creek, Creekside, Ross Downs, Whittier Heights, Montclair Parc, Lakes of Somerset and Woods of Colleyville, all part of the city’s subdivision roster (DFWMoves Colleyville directory).
- The Colleyville Nature Center at 101 Mill Wood Drive, west off Glade Road — 46 acres, nine ponds, about three and a half miles of trail (City of Colleyville, Texas Parks & Wildlife)
- McPherson Park at 240 West McDonwell School Road, on ground that was once one of the area’s dairy farms (City of Colleyville parks map)
- City Park on Bransford Road, L.D. Lockett Park, Reagan Park, Kimzey Park and Sparger Park (City of Colleyville)
- Colleyville Boulevard (TX-26), Glade Road, Pleasant Run Road, Bransford Road, Precinct Line Road and the Pleasant Run soccer complex at 6501 Pleasant Run Road
- Grapevine-Colleyville ISD attendance areas, including Colleyville Elementary on Pleasant Run Road, Colleyville Middle on Bogart Drive and Colleyville Heritage High on Heritage Avenue (GCISD)
- Retail, medical and office suites along the TX-26 corridor, where I handle rooftop units, small splits and walk-in coolers
Addresses near the Grapevine, Hurst and Southlake borders confuse people. Give me your cross streets and I will confirm in seconds that you are inside my daily radius.
One Brutal Summer, One Brutal Week of Winter
From June through September your system runs the better part of every day, which is exactly when a dirty coil, a weak capacitor or a crimped flex run stops being minor. I would rather find those in April.
Winter runs the other direction. The metroplex low reached minus 2 degrees during the February 2021 storm, with 139 unbroken hours below freezing (National Weather Service Fort Worth). Heat strips, uninspected furnaces and condensate lines in unconditioned space failed that week, and in shaded neighborhoods falling limbs took the power out too.
The takeaway is unglamorous: check the heat in the fall, keep a couple of feet of clearance around every outdoor unit, and wash the coils once the leaves are down.

Colleyville HVAC Questions
How quickly can you get here? Most 76034 addresses are a 10-to-20 minute run down Colleyville Boulevard or Precinct Line Road. You get a specific window when you call, not a vague afternoon.
How often do these coils actually need cleaning? On a heavily shaded lot, once a year at minimum and after a bad fall sometimes twice. It is the highest-value maintenance item in this city and routinely skipped for years.
My 1990s custom home has one room that has never cooled. New system or new duct? Almost always the duct, and I show you the readings from your own equipment rather than just asserting it. If that branch is undersized or the floor has no return capacity, new equipment underperforms on the first hot day.
Can you inspect a system before I close on a house here? Yes, and it is worth it on older custom homes. I document each system’s age and refrigerant type, check duct and attic insulation, and write up what you are inheriting and roughly what it will cost.
Do you do second opinions on someone else’s replacement quote? Regularly. It is a standard diagnostic call, and if the other contractor read the system correctly I will say so rather than undercut a fair quote with a worse install.
What about the shop, salon or office suite I own on TX-26? Light commercial and refrigeration are both in-house, so a rooftop unit and a walk-in cooler get handled on one visit and one invoice. Cooler failures go to the front of my queue because product is on the line.
Schedule an Inspection Before Anything Breaks
Any of these can be booked on its own, with nothing wrong:
- HVAC equipment inspection — condenser through air handler on every system, electrical and charge included, with a candid read on how much life is left
- Ductwork inspection — leakage, crushed and disconnected runs, undersized returns, and what correcting them costs
- Attic insulation inspection — what is up there against what should be, and whether topping it off pays you back
- Indoor air quality inspection — filter fit, ventilation and humidity, which earns attention on wooded lots where pollen and mold spore counts run high
Good timing: while you are still under contract on a purchase, before you list a house, before a builder warranty runs out, or when a room has never once been comfortable and nobody has explained why.
