Question DetailsAsked on 4/4/2012

I need to come up with a preventative maintenance program for a non profit entity with vary scarce resources. Are their any guidelines

The facility can't employ a maintenance engineer to work out a schedule so I have volunteered. The facility is around 26,000 sq ft with 5 Heat pumps-3 water heaters - 33 rooms with small restrooms - with either a shower stall or tub - each room has a PTAC for HVAC Facility has one central kitchen with 3 electric stoves and 4 gas stoves .
I would like to work out a monthly plan to cover and preventative maintenance (what time of year is best - # of times ect)
Any suggestions on where I might be able to locate a resource for this project would be appreciated.

Thank you

Are the heat pumps commercial or residential units?
Are the heat pumps Package or Split System?
Are there actually 33 PTAC units?
Are you an EPA certified person( refrigerant )?

Here is my suggestion, break it down into manageable portions(ie one heat pump and a few PTAC units every other month) to keep from being overloaded.
Clean/Replace filters
Check/inspect electrical wiring and connections
Check amperage draw of compressors/motors
Check capacitance of start and run capacitors
Check contractors/relays for wear/pitting
Check refrigerant levels and record superheated/subcooling
Check external static pressures across air handler(s)
Check deltaT (return and supply air temps)
Lubricate motors( if applicable)
Inspect Belts/Pulleys( if applicable)
Clean outdoor coils
Clean indoor coils

Start there and HAVE FUN!!!
