Colleyville homes don’t fail the way other North Texas homes fail. The systems are larger — often two or three separate HVAC systems serving different floors or wings of the house. Multi-zone configurations are standard, not the exception. And the equipment is premium-tier: Carrier Infinity, Trane XV, Lennox SLP, Daikin Fit. Diagnosing those systems requires manufacturer-specific tools and training — not the standard pressure gauge and multimeter that handles a typical residential repair.
The most common call we get from Colleyville isn’t “the AC isn’t cooling” — it’s “one zone isn’t cooling” or “the system is short-cycling” or “the thermostat is showing an error code.” Each of those points to a different failure mode. A damper motor stuck closed, a zone control board issue, or a communication fault between the thermostat and the equipment all show the same surface symptom but require different fixes.
The homes themselves work against the equipment in specific ways. Large square footage and high ceilings mean systems run longer and harder than they would in a typical home. Premium homes with custom features — theatre rooms, wine cellars, pool houses — create heat loads the original installer may not have accounted for. And builder-grade installations from 10–15 years ago, even on premium homes, often skipped the proper Manual J load calculation in favour of “what fits the budget” — meaning systems undersized for what the home actually needs.
It’s a Friday evening in July. You walk into the master bedroom and it’s 81°. The thermostat says 72°. You go check the kitchen and it’s perfectly cool — 71°. Two other zones are fine. Just the master.
On a multi-zone system, this usually traces to one of three issues: a damper motor stuck closed in the master zone trunk, a zone control board that’s failing on that specific zone’s output, or a thermostat communication problem on the master zone. The diagnosis takes minutes with the right tools. The repair is typically same-visit. But a technician without the diagnostic equipment for your specific system will often guess at the problem, replace the wrong part, and leave you with the same issue and a bill.
We don’t guess. We measure.
Step 1
Call 817-341-5142. A real person answers. Same-day service available. Tell us the equipment brand and what you’re seeing — it helps us send a technician with the right tools the first time.
Step 2
Equipment-specific diagnostic tools, communication checks, refrigerant pressure, zone-by-zone testing on multi-zone systems. We measure before we recommend.
Step 3
Flat-rate price before we start. Repair vs. replace numbers for older systems. Free second opinion on any written estimate you’ve already received.
Step 4
Most repairs same-visit. Premium-equipment repairs may run longer for parts ordering on rare components — we tell you upfront if that’s the case. System verified across all zones before we leave.
Colleyville’s larger homes and premium HVAC equipment need a technician who diagnoses correctly the first time — not someone replacing parts at random until something works. Hobson AC has been servicing multi-zone systems, variable-speed compressors, and communicating thermostats across North Texas since 1962. Same-day repair, flat-rate pricing, and a free second opinion on any written estimate.

Thanks, Comfort Experts for sending Jake out to check out my electrical issues. This one, I caused myself, Jake found the problem and fixed it in no time at all! He also performed a complimentary electrical check of my home’s GFI plugs and checked out my electrical panel and fuses. All passed with flying colors and I’m back in business with a brightly lit kitchen!

Matthew Hull was the technician who came to our home, he was friendly and answered any questions we had. While checking my systems he found a couple of items I will need to look into and provided me a quote if I was to have him fix them. After checking everything it was determined everything else was currently is in good order. I could not be more pleased with the professional service that we received.

I LOVE Justin Pennington’. My AC UNIT went down Friday @ 6pm of course. Justin came to my rescue on his way home. It wasn’t good news but as soon the part arrived Tuesday, he was here to install it. I wasn’t home. He took care of my AC, thermostat and my puppy dogs. HIGHLY RECOMMEND HIM!
