3 Signs Your AC Coils Need to Be Cleaned


xl18i-air-conditioners-lgBy now, your air conditioner has been working hard for a few months. For the most part, the system has been working OK. But if something feels off or you’ve noticed a gradual decrease in its cooling performance, you may want to consider a mid-summer maintenance appointment to get you through the rest of the season.

One of the most common issues we see in residential air conditioners is dirty coils. Your system has two sets of coils – evaporator coils in the inside unit and condenser coils in the outside unit. Both of these coils are crucial for absorbing heat and humidity in your home and releasing them outside. Over time, it’s natural for these coils to get dirty or blocked with debris. When that happens, the entire AC system becomes less effective and efficient.

Here are three telltale signs that your AC coils are dirty and need to be cleaned

  1. Your electricity bill has been going up. If you look at your utility bills and notice an unexplained increase, dirty AC coils could be to blame. Once you have the coils cleaned, your AC should go back to being more efficient and your electricity bill should go back to normal.
  2. Your unit seems to be running longer for no reason. When the AC coils are dirty, the unit has to work longer and harder to cool the inside space. You’ll hear the blower running and feel air coming out of the ducts for a long period of time. Not only does this contribute to the higher energy bills we just covered but it can put extra wear-and-tear on your unit, which reduces its total service life.
  3. Your home doesn’t feel as cool as it should be. If your coils are really dirty or blocked, then the heat is going to get trapped. Think of this like a traffic jam where the heat inside your home can’t move through the system to get released outside. So even if the AC is running, it will blow out warm or slightly cooled air.

Why use an HVAC professional for AC cleaning

Air conditioners are complicated systems and many of the components are very sensitive. So even if you’re a DIY homeowner, cleaning the evaporator or condenser coils in the AC isn’t a good job to put your to-do list. Performing the cleaning incorrectly could damage the system or put you at risk of an electric shock.

The good news is that scheduling air conditioning maintenance can be cost-efficient – and certainly cheaper than a repair service. When you factor in lower energy bills and an overall more efficient system, professional AC coil cleaning can virtually pay for itself.
