What All Hours Mechanical does

All Hours Mechanical is a privately held commercial HVAC, refrigeration, controls, and mechanical services provider headquartered in Groveport, Ohio (Columbus suburb), founded in September 2015 by brothers Tim and Ken Sargent. The company employs 75+ technicians and 4 project specialists across four regional offices — Columbus (Groveport), Cleveland (Macedonia), Cincinnati (Harrison, via the September 2025 acquisition of Genesis Mechanical Services), and Bowling Green, Kentucky — serving industrial, healthcare, education, government, foodservice, and multi-site commercial customers in Ohio and Kentucky. Its service portfolio spans scheduled preventative maintenance, on-demand repair, full equipment retrofit and installation, building automation system integration (including BACnet and VAV/VVT controls), commercial refrigeration, boiler and chiller service, and energy audits. The company holds Ohio contractor license #48061 and emphasizes 24/7/365 emergency response with sub-4-hour on-site capability across its service areas.

The business operates on a hybrid revenue model: approximately 80% of work volume is maintenance and repair (billed per service call or under recurring preventative maintenance contracts with flexible 1–52 visits/year frequency and monthly/quarterly/annual billing), while roughly 20% consists of project-based retrofit and replacement work. Pricing is quote-based and not publicly disclosed; free estimates are provided for planned installations and retrofits. The go-to-market is field-service-led and direct: customers initiate contact via dedicated local phone numbers or website forms, technicians are dispatched from regional offices, and the sales motion for larger projects involves on-site assessments, multi-option proposals, and direct engagement with facility managers and ownership. Marketing relies on local SEO, Google Business reviews, service-area pages, and word-of-mouth rather than paid digital advertising.

Strategic positioning centers on three differentiators: (1) multi-brand manufacturer certification across all major commercial HVAC OEMs (AAON, Bryant, Carrier, Mitsubishi, Daikin, LG, Raypak, Bell & Gossett, Lochinvar, Evapco, BAC); (2) complex-problem-solving capability for mixed-generation, aging, or hard-to-fix equipment that competitors decline; and (3) deep regional density across Ohio and Kentucky. The company is founder-owned and operated, has no disclosed external funding, and continues to pursue growth through geographic expansion (Kentucky statewide rollout through 2026) and tuck-in acquisitions (Genesis Mechanical Services).

Broad incumbents

• Carrier Global: Global HVAC and refrigeration equipment manufacturer that operates an extensive factory-authorized service network for commercial and industrial customers. Comparable as both a brand All Hours services (Carrier-certified) and as a vertically integrated incumbent competing for commercial service contracts.
• EMCOR Group: Largest publicly traded provider of mechanical and electrical construction, facility services, and industrial services in the U.S. Competes with All Hours on commercial HVAC, refrigeration, and controls service and maintenance, but operates as a diversified incumbent with national reach across many non-overlapping service lines.
• APi Group: Public holding company for safety, specialty, and industrial services including mechanical contracting and HVAC service businesses. Overlaps with All Hours in commercial HVAC and refrigeration service delivery but operates across many adjacent verticals (life safety, fire suppression, industrial) at much larger scale.
• Trane Technologies: Global HVAC manufacturer and commercial service provider operating a large factory-authorized service organization across the U.S. Overlaps with All Hours in commercial HVAC service, maintenance contracts, and controls work, but at substantially larger scale and with full OEM equipment revenue behind the service business.
• Johnson Controls: Global building technology company providing HVAC equipment, building automation systems (BAS), controls integration, and aftermarket service. Directly comparable to All Hours' commercial HVAC plus BAS integration offering (BACnet, VAV/VVT) for institutional and industrial customers, though at global scale.

Direct peers

• CoolSys: National provider of commercial refrigeration and HVAC service, maintenance, and installation for supermarkets, restaurants, and industrial customers. Closest direct comparable to All Hours' commercial refrigeration practice (walk-in coolers/freezers, reach-in units, ice machines, centralized systems) and overlapping 24/7 emergency response model.
• Limbach Holdings: Specialty commercial mechanical services contractor focused on HVAC, plumbing, and controls for institutional, healthcare, and commercial clients. Direct comparable to All Hours in service mix, customer verticals, and recurring maintenance contract revenue model, though operating at significantly larger scale and across more geographies.
• Comfort Systems USA: Large national commercial mechanical and HVAC services contractor with a multi-region branch model. Highly comparable to All Hours Mechanical because Comfort Systems' branch network performs the same HVAC, plumbing, and controls service, maintenance, retrofit, and emergency work for industrial, healthcare, and institutional customers that All Hours targets at a regional scale.
