When your HVAC system fails, your business suffers. Uncomfortable tenants complain, productivity drops, and emergency repairs cost three times more than preventive maintenance. Kahn Mechanical has served Dallas commercial properties since 1974, providing complete HVAC solutions that prevent breakdowns, reduce energy costs, and extend equipment life.
Our commercial HVAC services cover office buildings, warehouses, industrial facilities, retail centers, and multi-tenant properties across the metroplex. We handle rooftop units, split systems, chillers, boilers, heat pumps, and building automation integration. Whether you need routine maintenance, HVAC repair services, or complete system replacement, our licensed technicians bring the expertise and reliability that facility managers depend on.
Replacing aging HVAC equipment isn’t just about avoiding breakdowns—it’s about reducing energy costs by 20-35% and improving tenant comfort. Kahn Mechanical provides complete commercial HVAC installation services throughout Dallas, Richardson, Plano, and the surrounding metroplex. We work with property owners, facility managers, and general contractors to design and install systems that match your building’s needs and budget.
Our installation services include rooftop package units, split systems, VRF systems, commercial chillers, boiler systems, and energy-efficient retrofits. We help you access utility rebates that can reduce project costs by $20,000-$60,000+, and we offer financing options that make replacement feasible even when capital budgets are tight. Every installation includes complete documentation, warranty registration, and operator training.
From the Telecom Corridor to Las Colinas corporate centers, we’ve installed HVAC systems in every type of commercial facility. Our project managers coordinate with your schedule to minimize disruption, and we guarantee first-time inspection passage on every installation.
HVAC emergencies don’t wait for business hours. When your cooling fails during a Texas heatwave or your heating quits during a winter freeze, you need a contractor who answers the phone and arrives quickly. Kahn Mechanical provides 24/7/365 emergency HVAC service throughout Dallas, Collin, Denton, and Tarrant Counties with guaranteed 2-4 hour response times for maintenance contract customers.
Our service fleet carries common parts for immediate repairs, and we maintain relationships with equipment suppliers for expedited delivery when specialized components are needed. We service all major HVAC brands including Carrier, Trane, York, Lennox, and Daikin. Our technicians are trained on rooftop units, chillers, VRF systems, boilers, and building automation systems. We provide comprehensive AC repair services and don’t turn away complex equipment.
Whether you’re managing properties in Frisco’s growing corporate campuses or established office buildings in Garland and Mesquite, we understand that downtime costs money and threatens tenant relationships. We diagnose problems accurately the first time and provide transparent pricing before starting work. No surprises, no price gouging during emergencies.
Common commercial HVAC repairs we handle:
TTI, Inc. Testimonial
Emergency repairs cost 3-4 times more than preventive maintenance, yet most commercial properties operate reactively until a catastrophic failure forces action. Our customized maintenance contracts transform unpredictable HVAC expenses into fixed monthly costs while extending equipment life by 40-60%.
Property managers across Carrollton, Farmers Branch, Irving, and Richardson trust our quarterly maintenance inspections to catch small issues before they become expensive emergencies. This is especially critical during brutal Texas summers when rooftop units run at maximum capacity for months.
Every preventive maintenance visit includes:
Maintenance contract customers receive priority emergency response, discounted repair rates, and comprehensive service documentation, essential when presenting budgets to ownership or demonstrating due diligence if equipment fails.
Texas winters may be milder than up north, but commercial heating systems still require expert attention to maintain tenant comfort and energy efficiency. Kahn Mechanical provides comprehensive heating installation, repair, and maintenance for commercial properties throughout the metroplex.
We work with gas furnaces, heat pumps, boiler systems, radiant heating, and commercial unit heaters for warehouses and industrial facilities. Our heating services include emergency repairs during unexpected cold snaps, seasonal maintenance to ensure winter readiness, and energy-efficient system replacements that reduce utility costs.
Our technicians conduct thorough safety inspections, test carbon monoxide levels, verify proper ventilation, and ensure your heating system meets all building code requirements. When overnight temperatures drop and your heating fails, we’re available 24/7 to restore comfort to your building, because we know you can’t wait until Monday morning.
Dallas summers are brutal on commercial HVAC systems. When temperatures exceed 100°F for weeks at a time, rooftop units run at maximum capacity and aging equipment fails exactly when you need it most. Kahn Mechanical specializes in commercial cooling systems that survive Texas heat and keep your tenants comfortable.
Our cooling services include rooftop package unit installation and repair, chiller maintenance and replacement, split system service, VRF system installation, and emergency AC repairs with rapid response times. We serve office buildings in North Dallas, industrial facilities near DFW Airport, and commercial properties throughout the Dallas Medical District and Galleria Dallas corridor.
We understand the urgency when cooling fails, tenant complaints spike immediately, productivity drops, and in some facilities like data centers or healthcare buildings, equipment failure creates safety issues. Our technicians carry diagnostic equipment and common parts to resolve most cooling problems on the first visit.
Since 1974, Kahn Mechanical has been the commercial HVAC contractor that Dallas facility managers call when reliability matters. We’re not the cheapest option—we’re the contractor who shows up on time, fixes problems correctly the first time, and builds long-term partnerships with our clients.
