AIR CONDITIONING REPAIR
Commercial AC Repair in Southeast Michigan
When commercial cooling fails, downtime starts immediately. Friedman Mechanical dispatches certified technicians fast, diagnoses accurately, and repairs commercial AC systems right the first time 24/7, 365 days a year.
Commercial AC Failure is a Business Problem, Not Just a Comfort Problem
A failed rooftop unit over an office building means tenant complaints and lease friction. A down split system in a medical suite means rescheduled procedures. A malfunctioning cooling system in a server room or data center means something far worse.
Commercial AC repair requires speed, technical depth, and a team that understands what's actually at stake for the business. Friedman Mechanical has been handling commercial cooling failures across Southeast Michigan for over 35 years. Our certified technicians work on the full range of commercial cooling equipment from packaged rooftop units and split systems to chillers, air handlers, and VRF systems and our 24/7 service center ensures you're never left waiting for a callback.

Commercial AC & Cooling Repair
Rooftop Unit (RTU) Repair
Packaged rooftop units are the most common commercial cooling system in Southeast Michigan, and when they fail, the impact is immediate across the whole floor or building. We diagnose and repair RTU failures of all types — compressor issues, refrigerant leaks, failed economizers, motor and fan problems, controls faults, and heat exchanger issues — across all major manufacturers. Emergency same-day response available.
Split System Repair
Commercial split system diagnosis and repair for offices, medical suites, retail spaces, and server rooms. Refrigerant charge issues, condenser coil problems, failed contactors and capacitors, and controls malfunctions all diagnosed and resolved completely.
Refrigerant Leak Detection & Repair
Refrigerant loss is one of the most common causes of declining cooling performance in commercial systems. Our technicians perform thorough leak detection using electronic and UV detection methods, repair the leak at the source, and recharge the system to manufacturer specifications. We document all refrigerant handling in compliance with EPA Section 608 requirements.
Compressor Repair & Replacement
Compressor failures are among the most significant repairs a commercial cooling system can require. We evaluate repair vs. replacement economics honestly, execute compressor changeouts on all major system types, and verify full system performance before leaving the site.
Condenser & Evaporator Coil Service
Fouled or damaged coils are a leading cause of reduced efficiency and eventual system failure in commercial cooling equipment. Coil cleaning, fin repair, and coil replacement handled across all commercial system types and access configurations.
Controls, Sensors & Thermostat Repair
A significant percentage of commercial cooling "failures" are actually controls problems — miscalibrated sensors, failed thermostats, communication faults between the unit and the BAS, or programming errors. Our technicians diagnose the full controls chain before assuming mechanical failure, saving unnecessary parts and labor costs.
Zoning System Repair
Uneven cooling across zones is a common complaint in commercial buildings and is often traced to failed damper actuators, zone controllers, or sensor drift rather than the cooling unit itself. We diagnose and repair zoning systems across all major platforms.
Air Handler Repair
Fan and motor service, coil cleaning, belt and bearing replacement, VFD troubleshooting, and economizer controls repair for commercial air handling units.
Emergency AC Repair
Available 24 hours a day, 7 days a week, 365 days a year. When a cooling failure can't wait until morning, our service center dispatches a technician immediately. We prioritize commercial facilities where downtime has direct operational and financial consequences.
Chiller Repair
Commercial and industrial chiller diagnosis and repair including refrigerant circuit issues, heat exchanger fouling, condenser water system problems, and controls faults. Coordination with cooling tower service where required.

Commercial Heating Repair
Furnace Repair
Fast, accurate diagnosis and repair for commercial furnaces and boilers of all makes and configurations. We minimize downtime and get systems back online quickly, including 24/7 emergency response when it can't wait.
Boiler Repair
Commercial boiler systems require specialized knowledge of pressure, safety controls, and hydronic distribution. Our technicians service hot water and steam boilers of all sizes, including high-pressure systems in industrial and institutional settings. Services include burner repair, heat exchanger inspection, pressure vessel testing, CSD-1 compliance testing, and controls calibration.
Emergency Heating Repair
When a system fails outside of business hours, our 24/7 service center dispatches a certified technician immediately. We serve facilities across Southeast Michigan around the clock, every day of the year.
Diagnostic & Inspection Services
Not sure what's wrong? Our technicians perform thorough system diagnostics to identify the root cause, not just the symptom. You get a clear written assessment and options before any repair work begins.
Controls & Thermostat Repair
Heating performance issues are often a controls problem, not a mechanical one. We diagnose and repair digital and pneumatic control systems, building automation integrations, and thermostat/sensor calibration issues that cause inefficiency or uneven heating.

It helps to know the equipment manufacturer and model number, the approximate age of the system, and a clear description of what the system is doing (or not doing). That said, don't delay calling while trying to gather information — our technicians can assess on arrival.
-
We evaluate the system's age, repair cost as a percentage of replacement cost, current efficiency rating relative to available replacements, and the remaining useful life of major components. We present the analysis clearly and let you decide — no pressure either way.
-
Yes. We perform repairs regardless of prior service relationships. If you're unsatisfied with your current provider's response time or quality, we're available.
