Having an unexpected AC repair occur during the hot summer season can cause frustration to you and your family. Here we will go over some common causes of AC unit issues and how to fix them.
Common AC Problems and Possible Solutions to Fix Them
There are some reasons for an AC malfunction that you can resolve on your own. Other more complicated issues should be left to an HVAC professional. Here are some reasons your AC may be experiencing issues and how you can fix them.
Blowing Hot Air
It can be a big headache when you turn your AC on and it only blows hot air. Although this issue is common during summer, it may also be a simple fix.
First, check your thermostat batteries and settings. If the batteries have died, replace them and see if the issue is resolved this way. If the settings are incorrect, reset your thermostat. If both the settings and batteries are okay, check to make sure your circuit breaker hasn’t tripped. If it has, restart it by turning it on and then off.
Strange Smells & Sounds
If you have strange smells that occur when you turn your AC on but then it goes away quickly, it’s most likely because the air conditioner did not run for a long length of time. Make sure that your AC unit is clean prior to turning it on after the winter months. If there is a burning or gas smell make sure to contact a professional.
It’s best not to ignore weird sounds that your AC is making because this can signal a bigger problem. This issue can create worse things such as electrical problems so it’s best to contact an HVAC pro.
A Leak Around Your AC System
Your AC unit removes moisture from the air as it cools down your home. If you’re noticing leaks on the outside or inside of your unit, it’s a big sign that maintenance is required. A clogged drain is one reason your AC may have a leak.
Doesn’t Turn On
If your AC does not want to turn on, follow the same steps recommended above when an AC unit is blowing hot air. If you’re still not having any luck getting it to turn on, call a professional.
Frozen Coil
A frozen coil is caused when debris and dirt build up and stop your unit from receiving enough air to properly function.
Defrost the coil by unplugging the unit and allowing it to thaw out. Take a look at the unit and see if there are signs of debris and dirt buildup. Clean the areas that appear dirty so that the warm air will be able to reach the coil.
Unit Cycles On and Off
If your AC unit is turned on and off often damage can be caused to the fan and compressor. This is particularly true if this happens over a short time frame. This will stress the unit and the individual components and cause them to work harder each time the unit is turned back on.
It is best to have an HVAC professional inspect the unit and do a tune-up as acid can accumulate in these areas.
Weak Airflow
If you’re feeling hot and cold drafts in your home it may be due to weak airflow. Typically, weak airflow is caused by low refrigerant, dirty air filters, leaking ducts, and vent blockages.
Try recalibrating your thermostat if it seems to be faulty. Also, make sure to change or clean all air filters and make sure that there are no appliances or furniture blocking the vents.
AC Replacement vs Repair: What to Consider
There are a few things to keep in mind if you’re considering an AC repair or replacement.
Maximum Lifespan Has Been Reached
Every AC unit has a maximum service life. Newer, modern models tend to last 15-20 years whereas older models usually last 10-12 years. If your AC is over that lifespan time and you’re noticing issues begin, it may be time for a replacement.
Energy Bills & Usage
A higher-than-normal energy bill is a sign that your AC unit is working extra hard and expending more energy. An inspection done by a licensed professional can help you decide if your AC needs a specific type of repair or if it’s time to replace it.
Comparing the Costs
The cost of a replacement vs a repair is often the main concern of homeowners.
New air conditioning units can range between $2,500-$15,000 while repairs are much less. The average cost for central ACs range from $100-$650 and mini-split repairs are between $750-$900.
