Preventative HVAC Maintenance

Routine commercial HVAC maintenance programs are one of the most effective ways to improve HVAC reliability and reduce unexpected repair costs. Regular inspections allow worn components to be identified early while helping systems operate more efficiently throughout the year.

Our preventative maintenance services include the following:

• Change air filters to support airflow and indoor air quality
• Test the system in both heating and cooling modes
• Inspect evaporator coils for buildup or performance issues
• Add algae tablets to the drain pan to help prevent clogs
• Blow out condensation drain lines with nitrogen
• Tighten all electrical connections to reduce failure risk
• Inspect refrigerant lines for wear or damage
• Verify that the AC unit is level for proper operation

A proactive maintenance program can also improve energy efficiency and reduce long-term operating expenses.
