Light Commercial HVAC Services

Air Conditioning Southeast understands the challenges and decisions that developers, owners and facility administrators face during a commercial construction project. As Carrier and Bryant dealers, many of the contractors on our site provide comprehensive design, installation, repair and maintenance services for commercial new construction and retrofit applications.

New Construction/Upgrade

Typical light commercial heating and cooling systems have capacities that range from 5-25 tons and a lifespan of 10-15 years. Older systems tend to lose operational integrity and may experience reduced functionality over time. Whether an HVAC equipment purchase is targeted for new construction or replacement, it is important to establish a relationship with a commercial contractor who has extensive experience in system design and installation. Quality contractors consistently meet scheduling commitments, honor their bid price, rarely request a change order and remain flexible in meeting their customer’s needs.

Heating and cooling loads must always be calculated according to ACCA Manual J specifications, and the air distribution system should be sized using the latest ACCA Manual D publication. In new construction, a complete duct layout on the floor plan is necessary to account for obstructions, joists, fire walls and roof hips.

In the installation phase, rough-in technicians ensure that the air distribution system is installed according to the blueprint specifications, so the temperature and volume of air at the blower is not degraded by the time it reaches the register. After charging the system and checking for proper burner operation if a furnace is present, technicians test the system to ensure it performs according to design parameters. This includes verifying there are no duct or refrigerant leaks, and checking the system to confirm it has appropriate static pressure and return airflow.

Emergency Service/Repair

For many companies, reliable HVAC equipment is a necessity, especially for critical data applications. In general, as the size of the system increases, the expertise of the service technician becomes more specialized. This is particularly true for commercial chillers used in large institutional settings.

In emergency situations, identifying faulty components and quickly restoring system functionality is the main priority. Unlike residential applications where the emphasis is on occupant comfort, commercial HVAC equipment is often integrated into a company’s manufacturing or IT process. In data centers, temperature and air quality management can be critical in maintaining an uninterrupted flow of information to the different divisions in the facility.

Commercial HVAC service contractors understand the time sensitive nature of these malfunctions. NATE certified technicians use the latest high-tech diagnostic tools to rapidly discover the nature of the failure and affect only those repairs required to restore normal operation.

In the process, assessments can be made regarding equipment efficacy, and whether potential enhancements to the existing commercial air conditioners and heating systems can improve overall performance, reliability and efficiency.

Preventive Maintenance

For many companies, the continuous operation of a dependable and efficient HVAC system is essential for conducting business and maximizing productivity. A commercial HVAC maintenance agreement can help reduce costly downtime and save money on unnecessary repairs.

It is important to work closely with a commercial service company that is well versed in the complexities of commercial equipment. A 25 ton, 3 phase package unit is more complicated than a 5 ton residential split system, and the technician must be certified and trained accordingly.

Most commercial HVAC maintenance programs include important services designed to uncover potential problems before they become critical failures. This includes lubricating and cleaning vital system components and inspecting the controls, pumps, filters motors, relays, burners, capacitors and other important parts in the system. Refrigerant levels should be checked and adjusted as necessary. The dealer usually maintains a detailed service record for the equipment, and some contractors offer priority service for emergency situations.
