Unlike most heating systems, air conditioners have more complex mechanical systems that demand a variety of parts work correctly. Central air conditioners are designed to meet a certain “load” on the house and have a certain amount of refrigerant, commonly known as “charge”. They also need a certain amount of air flow across the coils. Should any of these things go awry; the system will not function properly.
We’ve compiled a list of four major issues that can go wrong with an AC and the solutions for them. Since air conditioners are more complicated and might not be easily resolved, we strongly recommend that homeowners call a professional air conditioning repair specialist.
Problem: Sometimes the air handler seems to be working fine, but the air coming out of the vent is weak.
Solutions: A dirty air filter and block return airflow, preventing the AC from supplying air to a home. Some systems have two air filters, one at a return grille and one at the air handler inside. Also, check the air registers to make sure they are open. Sometimes, homeowners close supply vents and registers in unused rooms to save money. Remove any furniture or curtains that are blocking open registers.
Problem: The thermostat shows that the unit is on, but it is blowing warm air instead. Most of the time, your system is low on refrigerant, or commonly known as Freon (which was actually a brand name for refrigerant that was banned years ago!)
Solutions: Be sure your air filter has been changed. Also, check your outside unit to ensure it is not dirty. When a condenser (outside unit) has dirty coils, it has a hard time releasing heat since the dirt is insulating the coils from the outside air. Cleaning the coils is easy: stop by your local hardware store for a coil cleaner, wear gloves, and follow the instructions on the cleaner. Be sure to turn your outside unit’s power off! When you’re done, turn the system back on.
Problem: Many people automatically turn to the solution of adding refrigerant, but there are multiple causes.
Solutions: Ask yourself the following questions:
There are many factors that could cause this issue. Call a professional air conditioning repair technician at Winters Home Services. We can run diagnostics and determine the cause of your AC issue.
Problem: Sometimes homeowners can detect the refrigerant leak themselves. You can also have a professional test it. But what causes the leak?
Solutions: Apply a leak seal treatment, or replace the leaky component if the product is under warranty. However, sometimes an empty system might hold hidden damages and requires more than a simple recharge. If the compressor is dead, a repair will not do it justice. See our article on “4 Signs Your Central AC System is Failing” to determine your investment.
