A new compressor for an AC unit can be 10s of thousands of dollars depending on the size of the space.

No more lugging around the compressor and hoses.

You can bring in a generator and a compressor.

Again, this is not a stab at all drillers but as a word of caution that this is typically more common with this type of tenant.There are several different job types and stages in the oil field.Beginning of a well:Construction crews (builds the pad)DrillersPipeliners (come and go as well depending on the current pipeline infrastructure or lack thereof)Truck drivers (equipment)Fracking crews.After well construction:Construction crews/welders (build compressor stations and/or transfer stations)Truck drivers.After well, pad and construction is completed: (These are your more steady, longer term tenants)Pumpers/gaugers (maintain the well and oil/gas production from the well.)Production employees (manage the flow of gas and oil and sends those products to the buyer)Mechanics/maintenance employees (maintains compressor stations and other equipment)Environmental regulatory compliance employees (small number of these people)Truck drivers.I'm sure I have missed a bunch and not every well and/or company operates exactly as stated but that is the basics of it.I'm not sure if you wanted to read all that.

That's a remodel of one/two units, a 2-3 HVAC compressors, more cash to pay a better PM.

Account Closed running an AC unit low on freon is guaranteed to destroy the compressor at some point.

Your tenants aren't changing the air filters.And a dirty air filter is the fastest way to lose a compressor, especially when there isn't enough return air on the house to begin with.

Compressors are expensive to replace.   

Ask your lender if they have a "work around"For the inspection,  a pressure test can be done with an air compressor to isolate the problem.
