There aren't many things more frustrating than an air conditioning that refuses to run. A hot, muggy home can make your space incredibly uncomfortable, which is why I have always focused on maintaining my air conditioning system. Unfortunately, I still run into problems from time to time and I am sure that all of you do, which is one of the reasons I decided to build this website. Check out these posts for more information about keeping your system working beautifully, even if you aren't naturally good at fixing things. You never know, making the right changes could dramatically improve your summertime experience.
Your central air conditioner has two sets of coils. The evaporator coils are in the air handler and the condenser coils are in the outside unit. The coils are connected by a copper refrigerant line, and these parts make up the refrigerant system of your air conditioner. If any of these parts develop a hole or are otherwise damaged, your air conditioner loses refrigerant and stops cooling your home. Here's how an air conditioning repair service may handle problems with your AC's refrigerant circulation system.
Just Adding Refrigerant Isn't An Option
When refrigerant leaks out of your system, your AC will continue to run, but the air is no longer cool. It's possible that a lack of refrigerant will cause the coils to freeze over and shut down your system. You might think a problem with low refrigerant could be fixed by topping off the system with new refrigerant, but that isn't always the case. The repair technician has to hunt for the leak and repair it before new refrigerant is added or the new refrigerant will slowly leak out as well.
Pinholes In Copper Can Be Soldered
Refrigerant that passes through the coils is in a gas or liquid state depending on the stage of cooling. Gas might be heard hissing out of a tiny hole or there might be bubbles on the line above a hole. Sometimes, the hole isn't as obvious, but a repair technician has tools and tricks for locating a hidden leak. If the leak is in the copper refrigerant line, it might be possible to solder it closed and solve the problem.
Coils Might Have To Be Replaced
If there's a problem with the evaporator or condenser coils, the air conditioning repair service might talk to you about your options. Sometimes, it's best to replace the coils instead of attempting repairs. Sometimes it's even necessary to think about replacing the whole condenser or air handler if your unit is old and near the end of its life.
You'll want to consider if your AC is still under warranty and if the damage to the coils is covered. If you're paying out of pocket, then you'll have to weigh the cost of repairs against the cost of replacement considering the expected lifespan of your AC.
Replacing coils can be expensive, but problems with the refrigerant system don't always mean there's a broken coil or hole. For example, dirty coils can cause your unit to ice over too, and that problem is easy and affordable to fix by cleaning off the coils.
