What Happens When You Call

Step 1: You call (430) 213-5796. A live coordinator answers during our operating hours. You’ll explain what’s going on with your system, whether it’s a furnace that won’t fire up in Far North Dallas or an AC that’s struggling through a July afternoon in Oak Cliff.

Step 2: We schedule an assessment. We’ll find a time that fits your schedule and tell you exactly when to expect us. You won’t be left waiting on a four-hour window with no update.

Step 3: You get a written estimate. Before any work begins, we put the price in writing. The number we quote is the number you pay. If we find something unexpected, we stop and talk it through with you first.

Step 4: The work gets done right. Our technicians complete the repair or installation, clean up the work area, and walk you through what was done. If a repair fails during the guarantee period, we come back and fix it at no charge.

Why Dallas Homeowners Call Us First

  • Written price before any work starts. The cost of your repair or install is put on paper before we touch a single component. No surprise charges when the job is done, no “while we’re here” add-ons. That’s The Kingswell Way, and it’s how every Coldharbour location operates.
  • Real arrival windows, kept. We tell you when we’ll be there and we show up in that window. Dallas traffic on 635 or the Tollway is real, so we build our schedule around it instead of pretending it doesn’t exist. If we’re running behind, you’ll hear from us.
  • Licensed and insured technicians. Every pro working under the Coldharbour name is required to hold the license and insurance their state requires. You’re inviting someone into your home; we take that seriously.
  • The Kingswell Guarantee in writing. Every repair is covered. If it fails inside the guarantee period, we come back and make it right at no charge. We put that promise in writing because a guarantee you can’t hold is not a guarantee.

Our Service Area Around Dallas

We serve Dallas and the surrounding communities, including Arlington, Irving, Carrollton, DeSoto, Coppell, Farmers Branch, Sachse, Addison, Highland Park, Sunnyvale, and Oak Lawn.

If you’re in a neighborhood we haven’t listed, call anyway. If we can help, we will.
