Q: Can an AC condenser be repaired?
A: If a condenser is damaged, the refrigerant leaks out and the air conditioning system stops working. A damaged A/C condenser cannot be repaired and must be replaced.
Q: Why does AC freeze up at night?
A: If there is not enough air flowing through your air conditioning system, your evaporator coil will eventually freeze up and cause your AC unit to freeze up and stop working. The most common cause of this is a dirty air filter. Dirt can also collect on the evaporator coil itself causing it to become clogged.
Q: What happens if AC coils break?
A: If any of the following symptoms sound familiar, chances are a broken evaporator coil is the culprit: Warm air is coming out of your vents, regardless of the temperature on your thermostat. Your air conditioner constantly starts and stops but your home isn’t getting cooler.
Q: How long do AC coils last?
A: As with any part of your cooling system, your evaporator coil will suffer from wear and tear over time. Efficiency gradually decreases throughout the coil’s lifespan, but proper maintenance can keep your evaporator coil going for up to 20 years. The primary reason for most failed evaporator coils is erosion.
Q: Where is the AC reset button?
A: Look for it first around on the exterior of your machine, especially along the bottom edge near the ground. An AC’s reset button is typically red and visible, so it should be easy to spot. If you don’t see a reset button on the outside, it could be located inside the unit behind the service panel.
Q: Why isn't my AC cooling down my house?
A: You might be low on refrigerant or have a worn out motor or a dirty evaporator coil. Not all AC problems demonstrate themselves with loud sounds or funny odors coming from your system. Some of them simply reduce the AC’s ability to run, and all you notice is less cool air in the house.
Q: What fails on an AC unit?
A: Parts like your compressor and fan blades as well as electrical connections can malfunction due to regular use. If a trained technician can replace worn-out parts before they actually fail, you may be saved an emergency repair call.
Q: How long do AC units last?
A: While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it’s fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Q: What are common AC issues?
A: Other common problems with existing air conditioners result from faulty installation, poor service procedures, and inadequate maintenance. Improper installation of a central air conditioner can result in leaky ducts and low airflow.
Q: Why is AC running but not cooling?
A: If your air conditioner is running, but not lowering temperatures inside, one issue could be a blocked or clogged condenser coil. When operating correctly, the condenser fan draws air into the outdoor unit through the condenser coil to pull heat energy out of your home.
