What Interstate AC Service does

Interstate AC Service LLC is a privately held, Tennessee-based commercial and industrial mechanical services contractor operating from Nashville since 2005. The company provides HVAC, plumbing, and building automation services across Middle Tennessee and Southern Kentucky, with four integrated revenue streams: subscription-based Facility Services Agreements combining preventative maintenance, priority response, and pricing discounts (10% on parts/labor, 20% on overtime); 24/7 emergency repair services; design-build and plan-spec commercial construction mechanical contracting; and direct parts sales.

The company holds ISN certification, Avetta listing, and Tennessee contractor license TN53063, and is certified as a Great Place to Work across three consecutive years.\n\nSince 2022 Interstate AC has operated as an acquisition platform, having acquired and retained the brands of Anchor Heating and Air Co., Bates Mechanical, Kimbro Mechanical, and Open Source Controls, while publicly seeking additional commercial HVAC and plumbing targets with $10-40 million in revenue or $2-10 million in EBITDA across the Southeast US. The company serves eleven industry verticals including data centers, industrial facilities, medical facilities, property management, restaurants, educational institutions, commercial office buildings, religious institutions, retail spaces, and warehouses and distribution centers, with named customers such as Elmington Capital, Cumulus Radio, Fifth Third Bank, ABC Supply, and Insite Properties.

Revenue model

1. Facility Services Agreements: Ongoing maintenance contracts providing regular HVAC and plumbing maintenance, priority emergency response, and discounted rates on repairs. These agreements create recurring revenue through monthly or annual billing with benefits including 10% off parts/labor and 20% off overtime rates. The commitment-free partnership model allows customers to maintain flexible arrangements while receiving ongoing service.
2. Emergency and Repair Services: One-time service calls for HVAC and plumbing repairs, available 24/7. Revenue generated from diagnostic fees, labor, and parts markup. Emergency services command premium pricing, particularly after-hours, and customers without facility agreements pay standard rates.
3. Construction and Installation Projects: Design-build and plan-spec mechanical contracting for new construction and renovation projects. Revenue from HVAC and plumbing system installations for commercial and industrial buildings, ranging from tenant improvements to ground-up construction. Projects bid competitively and through existing relationships with general contractors.
4. Parts and Materials Sales: Direct sales of HVAC and plumbing parts and components to customers, both as part of service calls and for self-perform installations. Margins vary by product category with commercial-grade equipment carrying higher margins than commodity items.
