HVAC Preventive Maintenance

“The cost for planned replacements is significantly less than the cost for unplanned replacements.”

What is HVAC Preventive Maintenance? Preventive maintenance is a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures.

The primary goal of preventive maintenance:

  • Prevent equipment failure before it occurs
  • Preserve and enhance equipment reliability
  • Replace worn components
  • Predictive recommendations to prevent downtime

Preventive maintenance activities include:

  • Equipment checks
  • Oil changes
  • Filter changes
  • Lubrication
  • Coil cleaning
  • Wire inspection
  • Freon checks
  • Partial and complete overhauls when needed
  • … and more.

All systems are maintained to factory-recommended standards and client’s needs.

Preventive Maintenance Benefits:

  • Extended equipment life
  • Optimum comfort conditions
  • Single source responsibility
  • Reduced system downtime
  • Lower expenses
  • A budgeted cost for maintenance and repairs

HVAC Repairs

Not all HVAC systems are the same and all our clients do not have the same equipment. That’s why Cullum Services does not specialize in one brand. Our technicians are trained and certified to work on all equipment. At some point that equipment is going to need to be repaired and we understand that sometimes it may be an emergency. We are experts in getting repair parts and having your system up and running the next day. This helps eliminate long costly down-times.
