Without routine maintenance, a commercial HVAC system can lose up to 20% of its efficiency each year. Many companies don't even worry about their HVAC systems as long as the air is cool in the summer and warm in the winter. The truth is that without regular maintenance, all units will lose efficiency, causing higher power bills and system failures.


Maintaining your HVAC systems can result in a 5-10% reduction in operating cost. By proactively caring for your building's HVAC system, you can save money by lowering utility costs and reduce the risk of costly premature replacement and increase service life of the equipment.

Preventative maintenance will maintain peak efficiency, prevent utility overpayment, avoid system failures and keep your tenants happy. At PMSI we offer planned service agreements that reduce emergency calls by revealing potential problems that can be corrected before causing major repair bills. These regular checkups are like changing the oil in your car, making sure you are always running at maximum efficiency.
