Contractors using HVAC Stack are outperforming their market.

The Problem

Owner Mark Reeves was spending 15+ hours a week building estimates by hand — pulling pricing from supplier catalogs, calculating load requirements, and manually adjusting for Phoenix's extreme heat conditions. His 28% close rate meant a lot of that work was wasted. He was turning down referrals because he couldn't get proposals out fast enough.

The Solution

• AI Estimating Agent generates full proposals in minutes using local supplier pricing, labor rates, and equipment specs
• AI Copilot provides instant code lookups for Arizona's unique energy efficiency requirements (IECC climate zone specifics)
• Multi-option proposals (good/better/best) generated automatically, increasing average ticket size

The Problem

Summit's estimating team was losing $60K–$100K per year in bid-day errors — transposed numbers, missed line items, incorrect labor multipliers on complex commercial installs. Their average bid turnaround was 9 days for a commercial project, and they were regularly losing to faster competitors. Two estimators were buried in spreadsheets instead of building relationships with GCs.

The Solution

• AI Estimating Agent cross-references equipment specs, labor tables, and local code requirements to catch errors before submission
• AI Copilot handles real-time ASHRAE and IMC code compliance checks during takeoff — no more flipping through reference manuals
• Automated bid assembly reduced turnaround from 9 days to 4 days on average

The Problem

Coastal was growing fast — from 3 techs to 8 in 18 months — but their newer installers kept tripping over Florida's updated building codes. 12% of installs were failing inspection on the first pass, costing $800–$1,200 per callback in truck rolls, labor, and parts. Owner Danny Vasquez was fielding angry calls from homeowners and burning profit on rework that shouldn't have happened.

The Solution

• AI Copilot gives installers real-time answers on Florida Building Code, IECC, and local amendments — searchable from a phone on the job site
• Pre-install compliance checklists generated per job based on jurisdiction, equipment type, and duct configuration
• New hires get up to speed 3x faster with AI-assisted code training instead of shadowing senior techs for months

The Problem

Heartland had a growing demand for energy audits driven by utility rebate programs and commercial building requirements, but their two certified auditors could only process 4 per week. They had a 14-week backlog and were turning away utility company referrals — their highest-margin work. Each audit took 6+ hours of report writing, and the bottleneck was documentation, not field work.

The Solution

• Energy Audit AI auto-generates audit reports from field data, photos, and equipment specs — cutting report time from 6 hours to 45 minutes
• Automated utility rebate eligibility matching — the system flags which rebates each customer qualifies for
• Standardized audit templates ensure consistency across auditors and meet utility program documentation requirements

The Problem

Jake Lindgren ran a one-truck operation doing residential installs and service calls across the Twin Cities. He was pulling 70-hour weeks — 40 in the field and 30 on admin: writing proposals, looking up code requirements for Minnesota's energy-efficient construction standards, invoicing, and answering the same customer questions over and over. He was too exhausted to take on more work and too stretched to hire help.

The Solution

• AI Estimating Agent generates proposals in minutes from a quick site assessment — no more Sunday night spreadsheet sessions
• AI Copilot handles Minnesota code lookups instantly, including the state's aggressive energy code amendments
• Freed up enough hours to take on 3 additional jobs per month without extending his work week
