4 Common Causes for AC Repair


Summer is not quite here yet, but soon enough temperatures will warm, and you’ll want to ensure that your air conditioning system is in good shape. Of course, this means paying close attention to any indicators of a problem and calling in a professional right away to service your system.

But, what if you are not familiar with the kinds of issues that an air conditioner might face? Well, you’re in luck. We’ve listed 4 of the most common AC repair issues; read on and learn about the issues your air conditioner could face–and schedule a tune-up with us so we can inspect and clean your system to help you avoid unexpected repair needs!

Thermostat Problem

Sometimes, a problem with the air conditioner might not be a problem with the air conditioner at all! We aren’t trying to confuse you, promise. It’s just that, it could be that you’re actually experiencing a thermostat problem. If this device isn’t registering the temperatures in your home correctly, you’ll find that your cooling system has to run longer to do its job, essentially “working harder.” This, or it won’t blow cool air, or it just won’t turn on at all.

Here’s our tip for you: Before you call our team in, double-check your settings on the thermostat. This might seem apparent, but sometimes a thermostat may be set to “fan-only” rather than “AC.”

Refrigerant Leak

There’s a common misconception that refrigerant is a fuel that “runs out.” On the contrary, upon manufacturing, your air conditioner is supplied with enough refrigerant to ideally last its entire 10-15 year useful service life.

If your air conditioner is losing refrigerant, it means you have a leak, and this can be detrimental to your air conditioner, leading to a multitude of problems, not excluding a complete system breakdown.

If you suspect you have a refrigerant leak–the air coming out of your vents might not be cool enough, or you could hear a hissing or bubbling noise coming from your AC unit–the best thing you can do for your system and for your comfort is give our team a call right away.

Ductwork Damage

Your air conditioner’s ducts are tasked with delivering cool, conditioned air all throughout your home. So, what if there’s damage somewhere in the air duct system? Well, then you can expect inefficient air conditioner operation, decreased comfort, and high energy bills.

In fact, ductwork with tears or pinhole leaks can account for up to 30% energy loss that you are still paying for.

Fan Issue

Your air conditioner has two fans within it to do its job–a fan that blows indoor air over the system’s evaporator coil in order to cool the air, and another that blows air over the outdoor unit’s condenser in order to expel heat outside.

If either one of these fans is malfunctioning–whether it be because of a faulty motor, a lack of lubrication, or worn fan belts–then you will wind up with poor airflow and all sorts of other issues. IF this problem is allowed to persist for too long, then your compressor can fail, which is, of course, something you don’t want to happen!
