HVAC & Electrical FAQ for Rockwall Homeowners

We serve Rockwall, TX and every community within about 30 miles, including Heath, Royse City, Fate, McLendon-Chisholm, Rowlett, Wylie, Sachse, Murphy, Garland, Sunnyvale, Forney, Terrell, Lavon and Princeton.

Yes. We hold a Texas mechanical contractor license (TACLA) and a Texas electrical contractor license (TECL). Most companies hold one or the other, which means a second contractor and a second trip charge when your HVAC problem turns out to be electrical.

Our diagnostic is $89 and it is waived when you approve the repair. You get a flat, written price before any work starts — we never bill by the hour.

Same-day for most repair calls and typically under two hours for a no-cool or no-heat emergency. We dispatch 24/7, 365 days a year.

Yes — $0 down with 0% APR for 24 months on approved credit, plus longer terms for full-system replacements. Approval takes a few minutes from your phone.

Always, and the cost is included in your quote. Every Rockwall County jurisdiction requires a permit for equipment change-outs, panel upgrades, EV chargers, and generators.

10-year parts and labor on new system installs, plus the manufacturer's registered equipment warranty. Repairs carry a one-year warranty on parts and workmanship.

Twice a year — cooling in spring, heating in fall. North Texas systems run far more cooling hours than the national average, and skipped maintenance is the single biggest cause of August compressor failures.

A straightforward change-out is a single day, usually 6–8 hours. Adding ductwork, a new pad and disconnect, or a panel circuit can push it into a second day.

Yes. We repair and maintain every major residential brand regardless of who installed it.

Yes — general liability and workers' compensation. We can send a certificate of insurance to you or your HOA before work begins.

Emergency after-hours dispatch carries a premium, which we quote up front before we roll a truck. There are no surprise line items on the invoice.

Most residential replacements land between $6,500 and $12,500 installed, depending on tonnage, SEER2 rating, and whether ductwork or a coil upgrade is needed. We quote flat pricing before any work starts.

A straightforward like-for-like replacement is one day. Complete system + ductwork revisions run two days.

For Rockwall's climate, a 15–17 SEER2 system is the sweet spot for payback. Going higher makes sense if you plan to stay in the home 10+ years.

Yes — $0 down, 0% APR for 24 months for qualified buyers, longer terms available.

$89 diagnostic, waived if you approve the repair. Emergency after-hours calls are $149 diagnostic.

For most common failures (capacitor, contactor, blower motor, refrigerant), yes — we stock those parts on every truck.

Rule of thumb: if the repair is more than 40% of a new system and the unit is 10+ years old, replace. We'll show you the math either way.

Yes — Trane, Carrier, Lennox, Rheem, Goodman, York, Amana, American Standard, Bryant, and more.

Heat pumps handle 90% of our winter comfortably and cost less to run. Gas furnaces still make sense if you already have a gas line and want raw output on the coldest nights.

$4,500–$8,500 installed depending on efficiency and venting requirements.

Yes — licensed for gas line runs, pressure tests, and Atmos coordination.

Most common causes are a dirty flame sensor, failed ignitor, or a tripped pressure switch. All in-truck-stock parts.

Emergency after-hours diagnostic is $149. Repairs are the same flat price day or night.

Twice a year: AC in spring, heat in fall. Bundle both for $149.

Yes — $89 flat for AC or heat. No trip fee, no diagnostic add-on.

Yes — our Comfort Club is $199/yr and includes two tune-ups, priority scheduling, and 10% off repairs.

Yes — modern inverters run efficiently down to about 25°F. Auxiliary heat kicks in below that.

Yes — federal 25C tax credit up to $2,000 plus Oncor rebates on qualifying models. We'll help you file the paperwork.

Single-zone starts around $4,200 installed. Multi-zone systems run $8,000–$16,000.

Yes — a properly sized single-zone handles most Rockwall two-car garages, even in August.

Most 200A upgrades run $2,800–$4,500 depending on service entry, grounding, and meter location.

You do if you're adding an EV charger, heat pump, hot tub, or ADU. And if your panel has a Federal Pacific, Zinsco, or Challenger label — replace it regardless.

6–8 hours typically. We schedule for a workday and you're back up before dinner.

$650–$1,800 depending on distance from panel and whether you supply the charger. Wall Connectors, universal J1772, and CCS all supported.

Often no. We check load with a clamp meter before quoting.

Yes — Rockwall requires a permit for a new 240V circuit and we pull it for you.

$8,000–$25,000 depending on square footage, attic access, and finish work.

No — we work room-by-room and restore power nightly.

$149 for one item, no trip fee once you're booked. Bundle 2+ items for volume pricing.

Yes — we install and set up the app on your phone.

Essentials-circuit systems from $8,500; whole-home from $14,000 installed.

Sometimes, with a large deductible. A $500 surge protector avoids the fight entirely.
