Question DetailsAsked on 7/27/2017

I need 1-2 lbs of R22 freon recharged in my garage AC system

Been diagnosed with a small leak but am selling the house and it took 2 years to loose 1-2 lbs. Anybody do that sort of thing anymore?

Sure - any Heating and A/C firm that does A/C servicing and repairs should be able to top off the system - common cost from about $150-200 at the low end to maybe $450 at the top end, particularly if you get one of the vendors who is marking Freon up 5-10 fold by referring to the publicized (but not true) "shortages" of R-22 because of its gradual phaseout over the next few years.

Bear in mind no guarantee the leak will not get larger - potentially pretty quickly, especially if due to a tubing stress crack or a leak in the evaporator coil due to corrosion, so no guaranteee it will not fail before the house sale closes - possibly causing closing issues if it fails at the most untimely time.

Also, knowing there is a leak that has not been repaired, that is something you would be required to report on the Real Estate Disclosure. So my recommendation, both with respect to risk avoidance and to fairness to the buyer, is get it fixed properly now rather than just topping off. Actually, assuming an HVAC tech found the low refrigerant condition, having the leak detected and fixed at that time would probably have been your most economic solution (if the repair was not so expensive that it brought in the replace rather than repair issue).

Course, if it is an evaporator coil leak, could run $1000-2000 range depending on system brand and size - which would bring up the question of repair versus replace so might put you right back to where you would probably be if the buyer demands replacement because the system is leaking.

[These days, if a buyer's inspector learns of a leaking A/C running R-22, he is likely to recommend they demand, as a contingency item total system replacement with an R-410a system, which might bump your risk $ up substantially - into the few thousand to maybe as much as $5000 range, if not repaired.]
