As title says....I noticed my lines were also freezing over on front of coil inside. So I called my cousin (hvac certified for 6 yrs) and he said it was probably low on freon. So he came up yesterday and immediately saw an oil spot under the outside unit. My unit is approximately 15 years old I do believe. He said he thinks either the coil around outside unit is leaking or something else. Either way he thinks the refrigerant line has a leak and the fact that its so old and parts in unit are so costly, I should replace outside unit and inside coil. He quoted me a price for all that and labor (2.5 ton unit I think) for $2000.
Any input would be greatly appreciated!!
