Preventative Maintenance

Preventative maintenance is the most intelligent way to protect your investment in your mechanical system. Utilizing regular preventative maintenance can extend the useful life of your equipment and reduce the possibility of expensive repair or replacement. Our preventative maintenance agreements are tailored to meet the budget and operational needs of your facility.

All mechanical equipment is designed to operate within certain limits. Air conditioning and heating equipment are no exception, and if not properly maintained, the equipment will exceed its design limitations and fail. The best insurance against failure & cost containment is PM.

W.G. Tomko, Inc. understands the value of an effective preventative maintenance program that our client’s mechanical systems require. Our customized maintenance programs will keep your air conditioning and heating components operating properly.

Key Considerations when evaluating preventative maintenance:

  • HVAC system maintenance isn’t expensive compared to what you might pay if your system degrades (and ultimately fails).
  • By tracking and routine maintenance, you can detect emerging problems before they reach the crisis stage.
  • It’s important to complete a life-cycle cost analysis when assessing whether you should repair or replace an aging HVAC system component.
