I’m Anthony Marquez. I own Air 4 North Texas, I answer my own phone, and I’m the one who shows up at your door — not a salesman, and not a different tech every visit.
Service calls run $89–$125. You’ll know the repair price before I pick up a tool.
Most HVAC companies around here won’t put a number on their website. I will. These are real ranges from real jobs — not a teaser rate that doubles when I get there.
| Job | Typical range |
|---|---|
| Service call & diagnosis | $89 – $125 |
| Capacitor replacement | $150 – $350 |
| Contactor replacement | $325 – $475 |
| Refrigerant recharge | $200 – $600 |
| Thermostat replacement | $200 – $650 |
| Blower motor | $800 – $4,200 |
| New straight-cool system, installed | $8,000 – $10,000 |
| New heat pump system, installed | $9,000 – $11,500 |
| 17–18 SEER2 high-efficiency system | $13,000 – $18,000 |
| Ductwork replacement | $6,500 – $18,000 |
Why the ranges? A capacitor on an easy-access unit is cheap. Same part on a rooftop package unit in August takes longer. I’ll give you the exact number over the phone or after a look — and I don’t start work until you say go.

Every HVAC company in North Texas says “family-owned” on their website. Here’s mine. When you call (817) 888-7998, you get me — and these four are the reason I’m not going to overcharge you or disappear on a job.
The big outfits send a salesman first, then a tech you’ve never met, and the price depends on which one showed up. I don’t have that problem. I quote it, I do the work, and I’m the one you call if something’s wrong six months later.

Residential and light commercial, across North Texas. Same guy every visit.
Nights, weekends, holidays. I diagnose the actual fault instead of guessing at parts, and I tell you the price before anything gets replaced.
From $89Straight-cool, heat pump, or high-efficiency. Load-calculated so you get the right size — oversizing is the most common mistake I find in this area.
From $8,000 installedSpring and fall. Coil cleaning, refrigerant check, electrical inspection, drain clear. The cheapest way to avoid a July emergency.
Leaky, undersized or crushed duct is why one room never cools. I fix the airflow instead of selling you a bigger unit.
From $6,500Garages, additions, shops, and rooms your main system was never sized to reach.
HVAC equipment, ductwork, attic insulation and indoor air quality — standalone, whether or not you buy anything from me.
I answer. Not a call center, not a voicemail tree. Text me a photo of the unit or the model sticker if it’s easier.
Service call is $89–125. If I can guess the problem from your description, I’ll tell you the likely repair range right then.
I find the actual fault and show you. Then you get a firm price before I touch anything.
Fix it today, or think about it. No pressure, no “today only” pricing, and I’ll tell you honestly if a repair isn’t worth it.
Air 4 North Texas is one person. I would rather show you nothing than put up a review I could not stand behind.
Every customer from here on gets asked for an honest review. When there are real ones, with real names, they go right here.

Based in North Richland Hills. These are the cities I’m in almost daily — and I’ll drive anywhere in North Texas for an install.
Further out? Hurst, Bedford, Euless, Grapevine, Saginaw, Haslet, Roanoke, Trophy Club, Flower Mound, Arlington and more get regular coverage — and for a system install I’ll go to Dallas, Plano, Frisco, Weatherford, Granbury or wherever the job is. Call and I’ll tell you straight whether I’m the right guy for your drive.
