Regular maintenance ensures the reliability and efficiency of commercial HVAC mechanical equipment. Investing in a Preventative Maintenance program can result in substantial long-term savings and a more comfortable working environment for your commercial space. As temperatures are starting to drop, here is a suggested checklist that should ensure your HVAC Mechanical equipment is functioning properly.
- Clean and Replace filters. Regular filter maintenance ensures better indoor air quality and system efficiency. Check monthly, change as needed.
- Check drain lines, clean around the condenser and evaporator coils. This is to prevent water damage, mold growth and debris from obstructing the mechanical equipment. Clean coils enables an efficient heat transfer and prevents energy waste.
- Lubricate Moving Parts. Fans, motors, and belts all should be inspected. Proper lubrication minimizes wear and tear to extend the life of the equipment.
- Test Thermostats and Controls. Verify that all thermostats and controls are giving accurate readings. Calibration may be needed to adjust for changing climatic conditions. Change batteries if needed.
- Monitor Refrigerant Levels for Heat Pump Systems. Regularly check and maintain refrigerant levels based on manufacturer’s specifications. Leaks or improper refrigerant levels can complicate cooling efficiency and lead to system damage.
- Inspect and Tighten Electrical Connections. Inspect all electrical connections, wires, and terminals for signs of damage, wear, or loose connections. Tighten or replace wires and connections to mitigate electrical issues. Embrittlement can cause not only damage to the wiring but what is attached to the wire itself.
- Inspect and Seal Ductwork. Leaks, cracks, or insulation damage can affect indoor air quality and thermal comfort.
- Open Registers. Air flow is the key to a healthy HVAC system. By opening them (and not blocking them) this enables optimum air to return to the system for conditioning. Restricting airflow can result in your system overheating, short cycling, causing higher utility bills, and costly repairs.
- Plan for Winterization. Prepare your heating system for colder months. In addition to what has already been written, inspect burners, heat exchangers, furnaces, heat pumps etc., to make sure they are running properly.
- Schedule a Comprehensive inspection by your trusted Haynes Mechanical representative. If you already have an existing Preventative Maintenance agreement with us, you can focus on your other responsibilities, and we will take care of the checklist so that your systems are running smoothly.
