HVAC Preventative Maintenance
HVAC Preventative Maintenance you and we understand. But should we handle it pro-actively or re-actively?
Reactive – allow the HVAC system to operate at less than peak efficiency for awhile, until it breaks, then replace or fix it as an emergency (and higher cost).
Proactive - participate in our HVAC preventative maintenance program. So which type of person are you?
Hint; If you change the oil in your car or truck regularly then you are a proactive person. Listed below is a checklist of suggested maintenance items
HVAC Preventative Maintenance SYSTEMS
Inspect at least twice a year, with seasonal start-up and run inspections.
Seasonal PM of chillers and boilers is involved; industry practice is to have a qualified mechanical contractor provide services. For cooling towers, disassemble screens and access panels for inspection; inspect the tower fill, support structure, sump and spray nozzles, fill valve, gear box, drive coupling, fan blades, and motor bearings; clean starter and cabinet; inspect wiring; check motor starter contacts for wear and proper operation; megger test the motor and log readings; and check the condition of the sump heater and contactor, and log observations.
Pumps usually require bearing lubrication at least annually. Inspect couplings and check for leaks. Investigate unusual noises. Air-handling unit maintenance should include cleaning or replacing air filters at least quarterly, based on condition.
PLUMBING
- Inspect at least annually; investigate any leaks or unusual noises.
- Domestic water booster and circulation pump systems require bearing lubrication at least annually; inspect couplings and check for any leaks.
- Domestic water heaters and boilers should be fire-tested periodically, using flue-gas analysis to adjust the flue draft and combustion air input to optimize efficiency.
- Remote drinking water chillers need condenser fan motor bearings lubricated annually. Check all contacts for wear and pitting, and run system control tests. Pump down the system and remove the refrigerant according to manufacturer instructions. Drain and replace oil in the compressor oil reservoir, including filters, strainers, and traps.
- Sump and sewage ejection pumps are replaced on an as-needed basis, but should be checked for function. Exposed pumps should be lubricated annually.
