Troubleshooting Tips: Why Is My AC Icing Up in Lake Oswego?

You might be surprised to find that your air conditioner is frozen — not during the coldest parts of winter, but in the heat of summer! Fortunately, troubleshooting AC freezing in Lake Oswego is easier than you think.

5 Causes of a Frozen Air Conditioner

Let’s start with the simplest problems before moving on to the more complicated ones. Keep in mind that troubleshooting AC freezing in Lake Oswego may require the services of a skilled technician, depending on the issue.

1. Your Thermostat Is Set Too Low

Running your AC at extremely low temperatures for long periods, especially when outside temps are around 60 degrees, can lead to ice buildup. Simply turn up the temperature before you go to work or step out for the day. If you want to automate this process, use a smart thermostat to raise the temperature when you’re not home.

2. The Filter Is Clogged

You should be replacing your air filter on a regular basis, anywhere from one to three months. Dirty air filters block airflow over the evaporator coil, causing condensation to build up and freeze — an issue that can be avoided with regular maintenance .

You’ll also have worse air quality without a fully functioning air filter, so switch them out before they get choked with dust, dirt, and other contaminants.

3. Vents and Ducts Are Blocked

A dirty old filter isn’t the only cause of airflow problems. You may have other restrictions, such as blocked vents, clogged or broken ducts, or even a design or installation flaw. The fix could be as simple as moving rugs and plants away from your vents, but it might require qualified technicians to investigate inside your walls.

4. The Refrigerant Is Low

Low refrigerant means less pressure in the lines, which can cause water vapor to freeze on the coil. Unfortunately, it also means there’s likely a leak. A skilled technician can identify where the leak is occurring and repair it.

5. The Blower Fan Is Broken

Similar to how clogged filters and blocked vents can restrict airflow, a malfunctioning blower fan can result in stagnant, unmoving air. This problem can lead to other serious issues with your HVAC system, so if you suspect the blower fan is the culprit, contact a repair company immediately.
