Commercial Preventative Maintenance


Quarterly Preventative Maintenance


Quarterly Preventative maintenance is the way to stay on top of the performance and efficiency of your business HVAC equipment.  It will help maximize your equipment life expectancy and we will maintain your heating and cooling equipment by making recommendations on replacing parts that are showing signs of failure so equipment downtime is minimized. This does not mean that parts will not fail unexpectedly, but with our Quarterly Preventative Maintenance Agreement, it will minimize the occurence of possbile part failures.


Also, utility costs are decreased because the equipment is working to its peak performance based upon the age of the equipment.  All commercial customers that have quarterly commercial maintenance do receive a discounted hourly rate on service call repairs and priority status on scheduling.
