Running a business in Dallas means preparing for summer heat that tests every air conditioning system to its breaking point. Your employees can’t focus when office temperatures climb into the 80s. Retail customers walk out when stores feel like ovens. Tenants start calling within minutes of an AC failure. The pressure lands on facility managers who need reliable contractors, not excuses.
Kahn Mechanical has served Dallas-Fort Worth commercial properties for over 30 years. We handle everything from routine maintenance that prevents breakdowns to emergency repairs when systems fail at the worst possible time. Our technicians specialize in AC repair in Plano and Carrollton AC services across office buildings, retail centers, warehouses, and industrial facilities. We understand that Texas heat doesn’t wait for convenient business hours, that’s why we’re available 24/7 when you need us. Whether your property is in Richardson, Frisco, or Fort Worth, we respond fast with the expertise needed to get your cooling system running again.
Most commercial buildings in Dallas rely on rooftop units (RTUs) for cooling, and for good reason. These self-contained systems handle both heating and cooling without taking up valuable indoor space. But Texas heat takes a toll. Units running at maximum capacity for 4-5 months each year wear out faster than equipment in moderate climates.
If your rooftop units are more than 12-15 years old, you’re likely dealing with frequent breakdowns and watching energy bills climb every summer. Modern RTUs use 25-35% less electricity while cooling more effectively. We handle complete rooftop unit replacements for buildings throughout the metroplex, from small retail spaces with single units to large commercial properties with dozens of rooftops. Our installation process includes proper equipment sizing (many older systems were oversized, which wastes energy), crane service for safe rooftop access, electrical upgrades if needed, and full testing to verify performance. We schedule installations during off-hours or weekends to avoid disrupting your business. Most properties see payback on new equipment within 4-6 years through reduced repair costs and lower utility bills.
Office towers, hospitals, data centers, and large industrial facilities require serious cooling capacity that rooftop units can’t provide. That’s where commercial chillers come in, delivering centralized cooling for buildings that need precise temperature control and redundancy.
We install and service industrial chillers throughout Dallas-Fort Worth, including water-cooled and air-cooled systems from 50 to 500+ tons. Chiller projects require specialized knowledge that most AC contractors don’t have, refrigeration expertise, hydronic system design, cooling tower integration, and building automation programming. Our team handles chiller replacements where one day of downtime could cost hundreds of thousands in lost business. We also provide emergency AC repair for existing chillers, because waiting 48 hours for service isn’t an option when your entire building loses cooling. For data centers and critical facilities in Plano, Frisco, and Richardson, we design redundant cooling systems that keep operations running even during equipment failures. Regular chiller maintenance extends equipment life by 10-15 years and prevents catastrophic failures during peak cooling season.
TTI, Inc. Testimonial
AC breakdowns don’t follow your schedule. Systems fail on Friday afternoons, holiday weekends, and the hottest days of summer when every contractor is swamped with emergency calls. You need a commercial AC contractor who actually answers the phone and shows up when promised.
Our emergency service trucks are stocked with common parts for faster repairs on major equipment brands. When you call our 24/7 emergency line, we dispatch licensed technicians who can diagnose and fix most problems on the first visit, compressor failures, refrigerant leaks, electrical issues, control board failures, and fan motor replacements. We serve properties across Dallas, Plano, Carrollton, Garland, Irving, and Mesquite with guaranteed response times for maintenance contract customers. Even if we’ve never worked on your property before, we’ll prioritize your call and get someone on-site as quickly as possible. Our goal is fixing problems permanently, not collecting repeated service call fees. That’s why we provide detailed repair recommendations, sometimes replacing one failing component makes sense, other times the system needs full replacement to avoid throwing good money after bad.
The worst time to discover AC problems is during a heatwave when temperatures hit 105°F and every contractor has a three-day backlog. Smart facility managers schedule preventive maintenance in spring, before cooling season starts, to catch small issues before they become expensive emergencies.
Our commercial AC maintenance programs include quarterly inspections, priority emergency response, discounted repair rates, and detailed documentation for your records. We check refrigerant levels, clean coils, test electrical connections, calibrate controls, and verify system performance under load. This proactive approach reduces breakdowns by 40-60% compared to properties that only call when something breaks. For multi-building properties or facility managers overseeing portfolios across Dallas-Fort Worth, we customize maintenance schedules that fit your budget and coverage needs. Many clients also add our Irving maintenance services or planned maintenance in Mesquite to cover specific locations. Regular maintenance also extends equipment lifespan by 5-10 years, delaying expensive replacements and protecting your capital budget. When AC systems are properly maintained, they run more efficiently, use less energy, and rarely fail during the critical summer months when you need them most.
