Common AC Problems in Davenport

Even though Davenport enjoys a generally mild coastal climate, the warmer months can still push your AC to its limits. Here are some of the most frequent problems homeowners encounter.


1. Low Cooling Capacity or Warm Air

One of the most common reasons people call for air conditioner repair in Davenport, CA is that their AC is blowing warm air instead of cool. This can happen if your system is low on refrigerant due to a leak, if your compressor is failing, or if a clogged filter restricts airflow.


Quick fix: First, check and replace your air filter if it is dirty. Make sure your thermostat is set to “cool” and the fan setting is on “auto.” If the problem continues, you may need a technician to check refrigerant levels and inspect for leaks.


2. Dirty or Clogged Air Filters

Air filters keep dust, dirt, and allergens from circulating through your home. However, if they are not replaced regularly, they can block airflow and cause your AC to work harder. This can result in higher energy bills, poor cooling, and even damage to your system.


Quick fix: Change your filters every 1 to 3 months. If you have pets, allergies, or live in a dusty environment, replace them more often.


3. Frozen Evaporator Coils

If your AC is not cooling properly and you notice ice forming on the evaporator coils, you may have a problem with airflow or refrigerant levels. A frozen coil can cause your system to stop working altogether.


Quick fix: Turn off your AC and let the ice melt completely. Replace the air filter if it is dirty and make sure nothing is blocking your vents. If the issue happens again, schedule a professional inspection to check refrigerant levels.


4. Thermostat Malfunctions

A faulty thermostat can prevent your AC from turning on or cause it to run inconsistently. In some cases, the thermostat may simply need new batteries or recalibration.


Quick fix: Replace thermostat batteries if needed. If your thermostat is programmable, check that it is set correctly. If you are still having problems, you may need a new thermostat installed by a technician.


5. Strange Noises

Your AC should run fairly quietly. If you hear grinding, banging, hissing, or rattling, it could be a sign of loose parts, a failing motor, or refrigerant leaks.


Quick fix: Turn off your AC to prevent further damage and call EVS Mechanical Inc. for a professional inspection. Ignoring these noises could lead to more costly repairs.


DIY Checks Before Calling for Professional AC Repair

Before calling a professional, there are a few simple checks you can make:


  • Replace the air filter to ensure proper airflow.
  • Inspect the thermostat to make sure it is set correctly and functioning.
  • Check the circuit breaker to confirm that your AC has power.
  • Clear debris from around your outdoor unit to improve airflow.
  • Ensure vents are open and unblocked inside your home.

If these steps do not fix the issue, it is time to contact a qualified HVAC technician.


When to Call EVS Mechanical for Professional AC Repair

While some AC issues can be resolved with basic maintenance, others require a professional’s expertise. You should contact EVS Mechanical Inc. if:


  • Your AC blows warm air even after replacing the filter.
  • You notice ice forming on the coils.
  • The unit leaks fluid or refrigerant.
  • There are persistent strange noises or smells.
  • The system frequently trips the breaker.
