Case Spotlight: 3-Hour Furnace Swap in Fort Worth

When the Ramirez family’s 20-year-old furnace failed on the first cold front of the season, our contractor partner relied on CountBricks to accelerate the rescue. Here’s how:

Before the Truck Rolled

• The technician dictated the problem description into the CountBricks mobile app while still on the phone with the homeowner.

• CountBricks AI generated three replacement options—80%, 92%, and 96% AFUE—each with live equipment costs from local suppliers.

• A branded proposal hit the client’s inbox within five minutes, earning instant digital approval for the mid-tier 92% unit.

On-Site Execution

1. The crew scanned the blueprint takeoff, and CountBricks displayed duct sizes and register counts for quick compatibility checks.

2. Photographic steps were prompted by the app, ensuring vent slope and gas pressure readings were documented in real time.

3. Because materials were pre-pulled based on the estimate, the physical swap—disconnect, lift out, set new unit, reconnect utilities—took just under three hours.

After the Install

• The final inspection checklist auto-populated, reminding the crew to test for carbon monoxide at each return grille.

• On completion, CountBricks issued the invoice, attached warranty registration forms, and scheduled a 12-month tune-up reminder.

Results

• 25% faster completion than the contractor’s historical average

• Zero pricing disputes thanks to transparent, line-item quoting

• Immediate payment captured through the CountBricks invoice link

Apply These Lessons to Your Next Project
