Preventive Maintenance Programs Pay for Themselves

It is no secret that Commercial HVAC systems can create costly repair bills but they can also be avoided a good share of the time. Preventative maintenance for your HVAC systems saves you money, avoids difficult downtime, extends the lifecycle of your equipment, and maintains tenant comfort. With Cooper Oates Air Conditioning, the comfort and efficiency of your building is our only priority.

24/7 Emergency Service Provides 24/7 Peace-Of-Mind

Emergency HVAC repair service is provided 24 hours a day, every day of the year. Our professional technicians are on-call whenever an emergency strikes your facility. Our administrative office team will coordinate the flow of information from our clients and materials suppliers to our field personnel, to get your facility back up and running. All Cooper Oates Air Conditioning contract clients are never charged over-time rates for emergency service.

You Can’t Manage What You Don’t Monitor

With the Cooper Oates Air Conditioning Proactive Building Monitoring Service you are able to minimize emergency calls, identify system inefficiencies, improve performance, and resolve issues more quickly if they do arise. Monitoring allows immediate warnings for unexpected failures and allows faster response times and specific failure data to speed the repair process.

Your “GO-TO” Source for All Your HVAC Projects

Our highly trained professionals are committed to creating comfortable indoor climates for the occupants of your building.  We do this by examining your current HVAC system to determine methods that may optimize comfort and air quality and thermal comfort. We then design, engineer, and install solutions that meet the needs of your tenants and your budget.
