Energy Savings

Preventative maintenance maximizes your equipment’s performance and efficiency, saving you money on energy.

This creates restrictive airflow and motors are forced to work harder resulting in loss of energy efficiency and a shorter lifespan of equipment. Having your A/C system serviced regularly will help you maximize your air conditioninging system’s life expectancy and save you from unexpected breakdowns that can lead to costly repairs.

Commercial AC Maintenance Tips

Change Air Filters Routinely

The most basic type of maintenance for your A/C system is changing your air filters. Most air filters should be changed every month. Some filters are designed to last up to 90 days, but in high heat or in buildings with high occupant traffic, filters should be changed more often.

Drain Line Cleaning

Flushing your drain lines on a regular basis will prevent a drain line blockage and possible water damage to your home or business.

Air Quality

With regular preventative maintenance and regular filter changes you can improve the air quality in your building/business. Unchanged filters can become a bed for fungal growth allowing particles to be distributed within your environment.
