When temperatures soar, your AC works hard to maintain a comfortable indoor temperature. Like other household equipment, your AC can develop problems over time for regular wear and usage.
The outdoor unit of an AC takes a lot of punishment every day. It is exposed to the elements and moisture. If not appropriately maintained, premature wear and tear can occur. Years of continuous operation can take a toll on your system’s health.
As ACs age, they start deteriorating and their efficiencies drop. If you do not move swiftly to fix an AC problem, it might snowball into a major concern that causes your AC unit to fail prematurely.
Let’s take a look at some common AC problems and their solutions typically seen by Walnut Creek air conditioning repair experts Connolly HVAC.
Dirty Air Filters
AC filters are designed to trap contaminants including pollen, dander, dirt, and dust particles. When a filter becomes clogged, it is no longer effective at trapping contaminants.
Clogged filters negatively affect indoor air quality and your AC unit’s performance. Your AC will have to work harder and longer to meet your home’s cooling requirements, causing AC parts to overheat and ultimately fail.
To prevent expensive repair and performance problems, replace the AC filters every 30-90 days. Consider replacing traditional filters with HEPA filters designed to trap more than 99% of all airborne pollutants.
AC refrigerant (or Freon) absorbs heat from indoor air. When the refrigerant charge drops, it affects your AC’s ability to absorb heat from indoor air. Some common signs of a refrigerant leak include frozen coils, strange noises, and registers not blowing cool air.
Since HVAC systems are hermetically sealed, a refrigerant leak is a warning sign that there is a hole somewhere in the system. These issues need to be found and repaired ASAP before any refrigerant can be recharged into the system.
Breathing in refrigerants in high concentration can lead to various health problems and even death. An unaddressed air conditioner refrigerant leak can damage your system.
Only experienced AC technicians are qualified to handle refrigerant leaks. If you notice signs of a refrigerant leak, immediately reach out to your contractor for help.
Here are some signs of a bad thermostat
➢ Your air conditioner suddenly stops working
➢ Room temperature does not match your thermostat setting
➢ Your thermostat is unresponsive
➢ Short cycling
Here are some things to try if your thermostat is acting up
➢ Make sure your thermostat is not running continuously
➢ If you have an electronic thermostat, check and replace the batteries if required
➢ Remove the thermostat cover and check wire connections
➢ Make sure your thermostat is placed in a cool area
➢ Clean your thermostat with a soft brush
If the problem persists, consult your AC technician in Walnut Creek.
Frozen Evaporator Coil
Evaporator coils absorb heat in indoor air and send conditioned air back into the home using air ducts. Sometimes ACs do not get enough air. This can cause the evaporator coil to freeze. A frozen evaporator coil can cause your system to stop working.
First, inspect the damage. To give your evaporator coil time to thaw, do not use the system for the next 24 hours. Consider using a hairdryer to speed up the thawing process.
In case of moderate frost, keep running your system on fan mode. After you successfully unfreeze your evaporator coil, have your contractor inspect your system for damage.
Water leaks are one of the most common and frustrating AC problems. There are several reasons why air conditioning units leak water from a damaged condensate pump to a clogged condensate drain line.
Using a wet or dry vacuum, unclog your clogged condensate pipe. If you have an algae problem, pour six ounces of vinegar down your drain line. To determine the exact location of your drainpipe, consult your user manual.
If you notice a puddle of water right under your coil or drain pan, your outdoor unit may have developed a leak. After you notice a leak, turn off your system and disconnect the power supply. After you switch off your AC, reach out to your contractor for help as soon as possible.
Electrical Control Failure
The AC motor, condenser fan motor, and compressor make an electrical connection that starts the unit. If your wires or terminals are corroded, there could be a disruption in the connection preventing the motor and compressor from turning on.
Check the electrical connection. If you cannot get to the root cause of the problem, have a technician look into the matter. You can prevent this problem with regular maintenance.
Condensate Drain Problems
Your AC’s condensate drain plays a vital role in preventing moisture from building up in your system. Your condensate drain can become clogged. To fix a clog, first, turn off the AC and check the tubing for holes or leaks. Using a suck vac, remove water from the drain pan and clear the drain of obstructions.
The AC condensate drain and pan are damp, providing ideal conditions for mold to grow. If you have a mold problem, flush your drain line with hot soapy water, peroxide, or bleach.
