Spring Commercial HVAC Checklist

Winter is a great time to start prepping for the warmer weather. Performing maintenance tasks before you use the system can ensure that it works properly as soon as those temperatures start rising. These tips can help you keep the unit running efficiently all summer long.

Unit Basics

Commercial HVAC contractors Minneapolis MN look at both the inside and outside units when they maintenance them. The two units work together to cool or heat a building. The type of units used depends on local climate, building needs and humidity levels.

Indoor Components

Regularly changing air filters keeps indoor quality cleaner and avoids clogs that can prevent airflow. Thermostats can help you save energy while maintaining a comfortable temperature in the building. The inside unit contains a drip pan that needs regular checking. Water in the pan can indicate a clogged drainage line. Cleaning the line out regularly prevents the unit from shutting off unexpectedly. Lubricate belts, clean the blower assembly, test safety controls, check the duct system, inspect the heat exchanger and tighten connections and wiring.

Outdoor Components

The outside unit holds the blades and fan motor that pump air from outside into the building. These components need regular cleaning to properly function. A dirty unit has to work harder to deliver air into the building. Inspect the switches, safety controls, control box and wiring for any damage. Clean the cabinet and coil and inspect the compressor. Recharge the unit if necessary after measuring the refrigerant level to keep cool air flowing into the building.

Maintenance Benefits

Besides enjoying cool air inside while the outside is hot, businesses can enjoy lower energy bills all year round. The HVAC unit is one of the highest energy consumers in the building. A low-performing system can cost a business thousands of dollars a year in energy bills. Regular maintenance keeps the unit in top shape and at its most efficient.
