  • 24/7 emergency service: Our technicians respond to critical system failures at any hour.

  • Highly trained technicians: Our technicians are trained to service complex commercial and industrial equipment.
  • Mobile emergency equipment: Mobile boilers and emergency HVAC systems can provide temporary heating while repairs are completed.

Emergency Commercial HVAC Repair Services

We treat a failure as an emergency when it affects your operation and cannot wait for a scheduled visit.

Common commercial HVAC emergencies include:
  • Loss of heat in cold weather
  • Loss of cooling
  • Boiler lockouts
  • Chiller failures
After you contact Aalanco, our emergency response follows these steps:
  1. Intake: We record the equipment type, the symptoms, and any error codes your staff has noted.
  2. Dispatch: We send a technician to your facility, day or night.
  3. Diagnosis: The technician finds the root cause and explains it before repairs begin.
  4. Temporary measures: If the repair cannot be completed right away, we discuss options for keeping your facility operating.
  5. Permanent repair: Many repairs are completed in one visit, while complex work may require a follow-up appointment.

When we correct the root cause, the same failure is less likely to happen again. After the repair, planned maintenance visits can catch early wear before it leads to another emergency.

Emergency Repair for Rooftop Units, Chillers, Boilers, and VRF

We provide emergency repairs for offices, industrial plants, schools, and retail stores. Each type of commercial system has its own failure points, so we tailor every repair to the equipment. For rooftop unit repair, we trace electrical faults, refrigerant leaks, and airflow problems. Our chiller repair work covers centrifugal, screw, scroll, and absorption chillers, along with their compressors and controls.

Our emergency boiler service covers steam and hot water systems, along with gas-, oil-, and propane-fired burners. When a boiler cannot be repaired immediately, a mobile boiler can supply heat and hot water until the permanent work is complete. For VRF system repairs and ductless system service, we review fault codes and check each zone, since one failed zone can affect the others.

We had an emergency A/C in the middle of a heat wave. Both Robin in customer care and Paul, the service tech were amazing and got us back up and running. Thank you for taking care of us!

I used this firm, many times, for commercial boilers systems, including one that very few contractors understood. They helped me lower the fuel use, along with a Mass Save contractor. Very large condo complex in Worcester with one massive common heating and cooling loop for 100 families.
