Question DetailsAsked on 12/16/2013

What should it cost to repair a R22 refrigerant leak on a 1.5 ton unit in Apopka, FL?

My 1.5 Ton R22 HVAC unit compressor is not running, and a tech said there was no refrigerant. He is trying to sell me on a new unit rather than the repair. The unit is 8 years old and has been used very little (it's a second unit for a spare room that is usually unoccupied - so the unit is usually off.

If the leak is in the indoor coil, the cost of the coil and replacing it,can be well over half the cost of the system if the coil is not covered by a ten year parts warranty. So often better to replace.

The compressor could have been damaged due to no refrigerant , that needs to be checked, but involves evacuating and recharging the system , expensive just for a test, and refrigerant will need to be recovered or it may be lost waiting on the coil, or repair of the leak where ever it is.

If the system has a valid 10 ten parts warranty, it may be worth the repair, if not I'd replace the system. matched systems, indoor and outdoor units are required by Florida code.

Did they say where to leak is?

In the Home > HVAC link under your question, you can find a number of discussions of the R-22 (Freon) issue - that it is being phased out, so just a refill can cost several hundreds $, and more every year in the future as it is phased out. With an 8 year oldl unit, you are likely well past half its life and probably more like 2/3-3/4 of the way through, so replacemennt to avoid putting good money after bad is not out of the quedstion.

Therefore, you are in a catch 22 - it could easily cost $300-500 to refill your system only to out your unit is fried - and if the compressor went out due to a freon loss (which also contains lubricant for the compressor) then that could be $ down the tube even if warrantied, because warranties commonly do not cover compressor failure due to coolant leakage unless the leak occurs in the warrantied compressor or exchanger itself - leaks in lines are generally not covered. If it failed due to an exchanger leak tht cannot be fixed, then you would have to replace exchanger AND compressor - the bulk of the system, so at that point you could be out 2/3 or more of the cost of a new system to repair a system that is going to cost a fortune for gas recharging down the line.

However, buying a new air conditioner is obviously a major expense too.

My suggestion - look into what it would cost for a portable or easily removable window unit, or to put in a scavenger fan with thermostatic switch to pull conditioned air from another air conditioned space to the seldom used bedroom to give it cool air when wanted, at a fraction of the cost of a new and seldom used air conditioner. That would put a bit more load on the other unit, but in extreme hot weather perhaps you could compromise on house temperature a bit, if necessary to keep it from cycling too frequently.
