What Does McCormick's AC Repair Service Include?
One technician checks the whole system: power, airflow, refrigerant level, coils, and compressor operation. Then we explain the problem in plain language and give you a written quote. When common parts are available, many repairs can be completed during the first visit.
Northern Colorado’s wind, dust, and long summer run times can clog outdoor coils and strain electrical components. If your system is low on refrigerant, we check for leaks first instead of simply topping it off.
Full System Diagnostics
Every visit starts with a complete diagnosis. We test the electrical, refrigerant, and airflow components to find the real cause, not just the symptom. Then we give you an upfront written quote before work begins.
Refrigerant Leak Detection & Recharge
Low refrigerant is one of the most common reasons an AC blows warm air. We locate and seal leaks, then recharge the system to spec. We identify your system’s refrigerant type, explain repair and recharge options, and handle refrigerants according to current EPA requirements.
Electrical Repairs
Common no-cool problems include failed capacitors, worn contactors, thermostat issues, and loose or damaged wiring. We test each component and replace approved parts when available on the truck.
Airflow & Coil Service
Weak airflow and ice on the lines usually trace back to a frozen evaporator coil, a dirty condenser, or a struggling blower motor. We thaw, clean, and restore proper airflow so your system cools evenly and stops overworking.
Compressor Diagnosis, Repair & Replacement
We test the compressor and related electrical components first. If a repair is practical, we’ll quote it. If replacement is the smarter long-term option, we’ll explain why before you decide.
Same-Day & After-Hours Availability
Most repairs are completed the same day, typically within one to two hours. If you need help after hours, our emergency HVAC team is on call when the heat won't wait.
