Contractors must hold a minimum of five years of commercial HVAC experience, a valid California C-20 license, Department of Industrial Relations registration, and successful completion of at least three similar rooftop replacement projects within the past five years. The scope encompasses replacement of four Bryant units (one 10-ton and three 5-ton) and one Lennox Gold Heat Pump 3-ton unit; disconnection and reinstallation of one Mitsubishi 12,000 BTU condenser unit; crane and rigging services with two separate mobilizations; disconnection and proper disposal of existing equipment including refrigerant recycling per Clean Air Act Section 608; installation of new equipment onto roof curbs or new curbs as required; reconnection of gas, electrical, and plumbing systems; installation of new condensate drain lines; replacement of electrical disconnects with code-compliant outdoor-rated units; and full system startup and testing. Onsite work is anticipated to span five consecutive days, subject to weather and field conditions, and will be coordinated with a separately contracted roofing contractor performing concurrent roof replacement.

The anticipated contract term is three years (2026, 2027, 2028) with options for two additional one-year renewal periods, for a maximum of five years total. Pricing must be submitted for all five years of the contract term, including any annual increases, with detailed cost breakdowns; an hourly rate for up to 20 hours of additional work is also required. AHA will evaluate proposals on qualifications and experience (30 points), proposed approach (20 points), customer service (10 points), cost analysis and budget (10 points), references (10 points), and lowest overall price (20 points). Prior to award, the successful proposer must provide proof of Commercial General Liability ($2 million per occurrence), Automobile Liability ($1 million), Workers' Compensation at statutory limits, and Professional Liability ($2 million), along with payment and performance bonds equal to 100 percent of scheduled costs. Warranty requirements include 2 years for workmanship and refrigerant, electrical, gas, and condensate piping leaks; manufacturer standard warranty for equipment; and 5 years for compressors and 10 years for heat exchangers. Questions are due October 13, 2026 at 4:00 p.m. through the Bonfire Portal.
