On a typical day, you don’t think much about your AC unit, or your HVAC system as a whole, unless it is giving you problems. These systems are very reliable, but they can experience issues from time to time.
If you have been struggling with your system lately and keep wondering to yourself, “Why does my AC keep failing?” Indianapolis’s best AC repair team is here to help.
Dirty Air Filters
Did you know that you are supposed to be swapping out your air filters regularly? If this fact is news to you, it’s most definitely time to head to the store to buy a new one.
The air filter in your HVAC system is designed to catch dust, dirt, and allergens as the air circulates through the unit and into the vents. If you have a dirty filter or if it is completely clogged, your AC unit works harder to move the air around. This can result in slow airflow or warmer air.
Broken Parts
AC units, and HVAC systems as a whole, have a lot of moving parts, and these parts can break or malfunction at any time. If your Indianapolis AC unit fails to work or has trouble producing cool air, you might have a broken part that needs attention. Worn fan belts, faulty motors, clogged drains and even issues with your thermostat can impact your unit’s ability to function.
Frozen Evaporator Coils
The evaporator coil is a crucial part of your HVAC system. Its main job is to remove heat from the air using a refrigerant that runs through a tubing system. Your blower, coil, and other parts work together to circulate cool air when your AC unit is running.
This refrigerant can get too cold and freeze up if the warm air can’t easily access it. This is often due to a build-up of dirt and dust on the coil, which acts as a barrier between the refrigerant and the warmer air.
Once the coil is frozen, your AC unit produces and pumps warm air throughout your home.
Try cleaning off your coil to see if it helps your system function more smoothly:
- Clean off visible dust with a towel or compressed air
- Scrub the coil to remove stubborn dust particles
- Spray the coil with a water/detergent mixture
If you ask yourself, “Why does my AC keep failing?” but you have never cleaned off your evaporator coil? This might be why.
Refrigerant Leaks in Indianapolis
You might love and rely on your AC unit in the heat of a classic Indianapolis summer, but do you know how it works? To cool down your home, your AC unit has to have refrigerant effectively moving through your system to create this cool air. Refrigerants absorb heat from the environment and work with evaporators and compressors to produce the cold air that flows out of your vents.
Your system can experience wear and tear as it works hard for you, which can result in loose lines or leaks. One of the most common reasons for a poorly functioning AC unit is a refrigerant leak!
Dirty Condenser Coils
Just like the evaporator coil, dirt and grime can overwhelm the condenser coil. Condenser coils are on the outside of your unit and work with an external fan to help cool the outside air as it moves through the system.
Since this part of your unit is outside, routine cleaning is essential! Dust, soil, leaves, and other yard debris can easily settle in your system and make it harder for the condenser coils to cool your space.
Pick a day to tackle this cleaning and then get to work:
- Make sure all power is off
- Clean up around the exterior of the unit
- Wipe off fan blades and clean out leaves, dust and debris
- Wipe down coils or spray the unit with water to clean it off
