Repair Freon Leak from Central Air Conditioner?

Question

6 years ago was the last time my central air kept my house nice, cool and comfortable for the summer. I was told by the gentleman recharging the freon that I will only have enough freon to last me for that summer. He said I have a leak from a coil which house the freon. Are there any DIY suggestions I can get before I call in a professional or purchase a new unit?
I live in a subdivision with 70% single moms owning homes. Any suggestions will wisen the old wives.

Thanks

if there are indeed any sealant, where can I purchase it.

Thanks Jeff G for your speedy response.

Answer 1

Unfortunately, if you have a leak, a professional will have to deal with it.
The hard part is finding someone who is not a clueless idiot and knows what he's doing and has experience. I've been doing HVAC work for 29 years and I know there are a lot of people either not really trained properly or they try to rip you off.
If the system is over 8 years old and you aren't having any luck with people finding and repairing the leak (some are easy to find, others seem impossible), you should replace it, piping and all. If it is newer than 6 years old, maybe a reputable company can find and repair the leak. Maybe try Consumer Reports magazine to find the best in your area.
Good luck.
By the way, where do you live? Being a single guy, I'd love to live in a neighborhood with 70% single moms. I'll even take a look at your A/C if you fix me dinner.

OK your unit has a leak which takes 6 years to cause a problem. Live with the leak and get it recharged. This is a cost effective repair. You are going to have to pay for pump down and removal of freon. replacement of leaking item or repair. A further pump down and refill. The gas cost will be the same plus all the extra costs of labour. By the way if the leak is only slight, the bubble test will not work!

One of the most difficult and costly tasks for air conditioning equipment owners is servicing a system that has a refrigerant leak. Most air conditioning service companies will not find or repair leaks. They either replace the refrigerant lines, replace compressors, condensers or other components or just charge the refrigerant lines with a sealant in the hope that the leak is stopped - but that won’t find and permanently repair the leak. And it costs a lot of money – your money!

As an owner, you know that refrigerant leakage can cause air conditioning units and chilled water plants to work harder, increasing utility bills and can cause compressors to overheat, which often causes permanent damage or system failure. Plus, in a lot of situations, the release of Freon to the atmosphere is a violation of Environmental Protection Agency (EPA) regulations.

We are a service group that provides a new and unique way to detect and repair refrigerant leaks – from inside the refrigerant lines. Our unique system and trained technician will identify and repair the leak, usually in one site visit and no sealant are ever used. This is a permanent and economical fix!

While we are headquartered in Taipei, Taiwan R.O.C., we are happy to announce that we are launching a new repair branch in New Jersey. We are looking to expand our services and are open to discussions on growing the business and partnering. And we offer an up-to20% referral fee for new business.

If you or one of your industry colleagues is interested in our services as an equipment owner or discussing possible business ventures as an air conditioning service provider, call now at [phone] for a consultation.

if its a hole in your coil 99% of the time the coil will have to be replaced but often people assume its the coil before looking for the actuall leak if there is any freon left in your unit you can test it to see where the leak is at by getting a empty spray bottle and putting some dish soap in it and fill it with water shake it all up and spray all joints if any of the joints start to blow bubbles you have found your leak which can be re brazed but the system would have to be empty off all freon coolant before doing this (in nj where I live you need a hvac license to even touch coolant) bout I have heard of sealers that you can put on the outside to seal it with out draining the line but ive never used any good luck

Answer 7

You have gone six years without cool air why do you need it fixed now? Your unit is not new, so if the coil is leaking get a new energy efficient unit. If its the pipes you can braze the leak. If you just need it once in a while like when a grand baby is visiting, or a grand parent, you can get a window unit for one large area - not the whole house. This is the cheapest way to go.
