How often should I have shop air conditioning serviced?
I am currently looking into leasing a shop, the one we are looking at has got 2 air conditioning units. I am just woundering if anybody can help me with these? Things like, How often should I get them serviced?, How much will it cost? How much will they cost to run? etc.
Thank You.


If air conditioning units are not serviced regularly they can spread disease but I am not sure where the law stands on how often you need to service them.
It really depends on what you’re doing in the shop. Are you generating a lot of dust? Any AC should be serviced at least annually, but commercial units more often. Return air filters should be changed at least monthly, more often depending on circumstance.
Do everything you can to service them yourself first. Then see how they work. Most AC service consists of simple cleaning of filters, coils, ducts, and electrical components. make sure all fans are oiled in accordance with operater manual. If you do your homework you can do the same basic service on an air conditioner that they do. It’s like changing the oil and stuff like that on your car.
Once a month, change filters in both units whether they need it or not. Use disposable filters. The washable type cut off air flow and ckoke the compressor. If the indoor fans are belt driven, check the belts once a month. If you have condensate pumps, add one cup of bleach to them once a month.
Twice a year, have outdoor and indoor coils cleaned. A little maint. now can save you thousands in the future.
