Signs Your Commercial AC System Needs Repair
Commercial AC systems signal trouble before they fail completely. Uneven cooling across zones, warm air from supply vents, electricity bills spiking without explanation, or a frozen evaporator coil are the clearest indicators. Unusual compressor noise — grinding or rattling that wasn’t there last season — usually points to a bearing or fan blade problem.Condensate drain backups show up as ceiling tile staining; Portland Metro’s humid winters make commercial drain lines clog faster than most expect. Pre-2010 units still running R-22 refrigerant change the repair-vs.-replace equation. R-22 is no longer produced — recharging is expensive and temporary. Replacement usually makes more financial sense. See all air conditioning services Conrad offers.
Split System Commercial AC Repair
The most common configuration in light commercial buildings — a separate outdoor condensing unit paired with an indoor air handler. Conrad repairs refrigerant leaks, failed compressors, worn capacitors and contactors, dirty or iced evaporator coils, and blower motor failures. Most split system repairs are diagnosable and completable same-visit when common parts are on the truck. All major brands serviced.
Packaged Rooftop Unit (RTU) Repair
Standard in many Portland Metro office and retail buildings — a single cabinet on the roof handles both heating and cooling. RTU failures often come down to economizer damper malfunction, condenser and evaporator coil fouling, fan motor failures, and gas valve issues on gas-electric units. An economizer stuck open in winter wastes heat; stuck closed in summer blocks free cooling. Conrad services all major RTU brands.
Commercial Ductless Mini Split Repair
Multi-zone ductless systems are increasingly common in commercial spaces — server rooms, individual offices, and additions where running ductwork isn’t practical. Common failures: inverter control board issues, refrigerant undercharge, condensate pump failure, and outdoor unit defrost board malfunctions. Conrad services Daikin, Mitsubishi, LG, Bosch, and other major commercial ductless brands. Written diagnostic report after every visit.
How Conrad Diagnoses and Repairs Commercial AC Systems
Every commercial AC service call starts with a systematic diagnosis. Conrad’s technician checks thermostat and control signals, refrigerant pressure at suction and discharge, amp draw on compressor and fan motors, condenser coil condition, and economizer damper position on RTU systems. On ductless units: inverter board codes, condensate pump function, refrigerant charge.
No work starts until the flat-rate quote is accepted. Same-visit repairs completed when parts are on the truck. Larger replacements — compressor, RTU blower motor, heat exchanger — scheduled with a clear timeline. Every call closes with a written diagnostic report. A commercial HVAC maintenance agreement prevents most of these calls before they happen.
Emergency Commercial AC Repair — Portland Metro
For commercial clients, a failed AC unit carries real costs. A restaurant kitchen at 90°F is a food safety issue. A medical office without cooling faces patient safety and regulatory concerns. A retail space loses customers by the hour on a 95°F July day. Portland Metro’s summer heat events now run multiple days — commercial buildings are exposed faster than residential properties.
Conrad offers emergency dispatch 24/7 across Beaverton and Portland Metro. Stocked trucks mean most common commercial AC failures — capacitor, contactor, refrigerant charge — get resolved on the first visit.

Why Choose Conrad for Commercial AC Repair?
Expert Technicians
Conrad’s technicians are CCB licensed and EPA608 certified — trained on split systems, packaged rooftop units (RTUs), and ductless mini splits across all major commercial brands. Every tech is background-checked and works in-house. The technician who diagnosed the issue handles the repair — no relay dispatch to a different crew. Conrad carries tools and reference data for RTU economizer diagnostics, inverter board error codes, and refrigerant pressure analysis on all major commercial system types.
Prompt Service
Commercial AC failures cost businesses money by the hour. Conrad offers same-day service across Portland Metro and 24/7 emergency dispatch for urgent situations. Service trucks are stocked with capacitors, contactors, refrigerant, and other frequently replaced commercial AC components — most common failures are resolved on the first visit without parts-ordering delays. Larger repairs are scheduled with a clear timeline and no open-ended waiting.
Everything In-House
Conrad handles commercial AC repair, maintenance agreements, and equipment replacement recommendations within one licensed team. The same technician who repaired the system can assess whether a maintenance agreement makes sense going forward, or whether aging equipment is approaching replacement. No referrals to a separate commercial contractor, no handoffs between a service team and an account manager.
Customer-Centric Approach
Every commercial service call closes with a written diagnostic report — what was found, what was repaired, what parts were used, and what to monitor. The flat-rate repair cost is communicated before any work begins. For facilities managers or business owners, Conrad can also provide documentation suitable for maintenance records or landlord reporting. No surprise invoices after the technician leaves.
