No, air conditioners are classified as improvements and depreciated over the useful life. See link below, Ch. 2, page 5, Table 1-1
If you installed a window air conditioner, for instance, you could deduct the cost under Rental Expenses.
If you installed a central air conditioning system ,however, that is considered a Capital Improvement and would be depreciated for 27.5 years, the same as the rental property itself.
If this is your situation, here's info on how to add an improvement as a Rental Asset.
Go to Assets/Depreciation from the Rental Summary screen.
You may have the option to expense certain improvements under the Safe Harbor Election for Small Taxpayers. When you begin the Assets/Depreciation section, TurboTax will ask you about this. If you want to deduct the cost fully this year, answer "yes" to include the this election on your return.
If your improvements don't qualify, or you simply wish to depreciate the cost over 27.5 years, continue through the Depreciation interview to set up a new asset.

If this is a window unit then it's classified as equipment or as an appliance and depreciated over 5 years. Otherwise if it's a central A/C unit then it's classified as residential rental real estate (since it becomes "a material part of" the property) and depreciated over 27.5 years.
I could use some accelerated depreciation on a rental property. I've installed new "mini-split" air conditioning units that are somewhere between window and central air. Any chance I can depreciate these over a shorter than 27 year period? Each, including installation, about $7500.
HVAC now qualifies for Section 179 expense deduction; however, in order to take advantage of it your property will have to show a profit. As for depreciation, if they are part of the central HVAC system you have to depreciate them over 27.5 years. If they are stand alone units, more like window AC units (i.e. not a part of the structure of the building) then you can depreciate them over a seven year period.
On HVACs in nonresidential property qualify. HVAC for residential rentals does not qualify for section 179.
Yes, it is depreciated over 27.5 years. No, you don't keep depreciating it after it is gone. When the old AC is gone, you report that disposition (essentially you sold it for $0) and the undepreciated amount will show up as a loss on Form 4797.
I do not know how the below is dealt with on *commercial* rental real estate, as I've not researched it. But I would expect it to be treated exactly the same as is required for *residential* rental real estate.
There is a different kind of A/C system referred to as "ductless". With this type of system a single compressor unit is located outside of the structure. Then individual cooling units are located inside one or more rooms of the house. You only have about a 2" hold in the wall or ceiling for the refrigerant lines to pass through to the compressor located outside. Hence, no air ducts.
These types of units are generally more economical because each inside unit has it's own thermostat and only operates when activated by the thermostat. These ductless setups are treated exactly the same as any other central A/C setup. The ductless units are not portable and do "in fact" become a physical part of the structure. So they classified as residential rental real estate and depreciated over 27.5 years. Take note that this does *not* qualify for the Special Depreciation Allowance either.
As for the SEC179 deduction, residential rental real estate and it's associated assets do not qualify for that at all.
