Question DetailsAsked on 8/8/2016

I had a technician come to my house to fix my A/C because it wasn't blowing cold air, he put freeon worked 15 days,

then back to warm air, called him again and now he says since your unit is so old you would need a new unit, does this sound right? shouldn't he have known it it had a leak?

Do you have the same question? Follow this Question

Here is a link to a similar previous question with response that might be of interest to you -

But yes, generally a significant loss of gas would indicate that he should have looked for (and found) a leak. Not saying where the leak is, one could not evaluate (considering cost, age of unit, how long you intend to stay in the home, how badly the A/C is needed if it goes out again, long-term economics, availability of funds to replace it, etc) whether replacement is something you should consider. For instance, a leaking gas fill/gage connection or threaded connection leak might be fixed in minutes, and many sources of leaks that do not involve a leaking evaporator coil can be fixed for a couple hundred $ or so - certainly not justification by itself to replace the whole unit in those sort of cases.

Plus just refilling without fixing the leak (assuming it took more than a minor amount of gas) is likely to cost you unneeded fees for recharging and for the replacement gas at each refill.

You can find a number of other previous responses to the repair/replacement issue, and the life cycle costs and economic issues involved, as well as typical evaporator coil repalcement costs if that is the leak source, in the Home > HVAC link in Browse Projects, at lower left.
