At Lane Heating & Air, we understand the discomfort and inconvenience that come with air conditioner issues, especially during the warm seasons in Lake City and Gainesville, FL. Recognizing common air conditioner problems and knowing their solutions can significantly enhance your comfort and prolong the lifespan of your unit. Here, we delve into prevalent issues and provide expert solutions, ensuring your AC system operates efficiently and reliably.

Common Air Conditioner Problems

Insufficient Cooling

One of the most reported issues by homeowners is the air conditioner failing to cool the home adequately. This issue may stem from several sources, such as clogged air filters, depleted refrigerant levels, or obstructed airflow.


  • Regularly replace or clean air filters.
  • Schedule an AC repair service in Gainesville, FL to check for and fix refrigerant leaks.
  • Ensure that all vents are open and unobstructed to improve airflow.

AC Unit Not Turning On

Another frequently encountered issue occurs when the AC unit fails to power up, often resulting from a tripped circuit breaker, defective wiring, or a thermostat that isn’t working correctly.


  • Inspect the circuit breaker and perform a reset if needed.
  • Verify the thermostat settings and replace the batteries if needed.
  • Contact our expert team for comprehensive AC repair in Lake City, FL to diagnose and correct electrical issues.

Strange Noises

Weird sounds coming from the air conditioner, such as grinding, squealing, or rattling, indicate mechanical problems within the unit.


  • Grinding noises may point to a problem with the air handler’s bearings and require professional AC repair in Gainesville, FL.
  • Squealing noises might be due to belt issues, which should be replaced by a technician.
  • Rattling often suggests loose components that should be tightened during a maintenance check

AC Unit Leaking Water

Finding water leaking from your AC unit can be alarming. This usually results from a clogged condensate drain line or a malfunctioning condensate pump.


  • Clear the condensate drain line of any blockages.
  • Verify that the condensate pump operates properly. If it doesn’t, professional repair or replacement may be required.

Short Cycling

Short cycling, where the AC unit turns on and off more frequently than normal, can significantly reduce efficiency and increase wear and tear on the system. This inconsistent operation not only escalates energy costs but may also prematurely diminish the longevity of the unit, posing a risk of unexpected failures and necessitating more frequent replacements or repairs.


  • Examine the air filter for any dirt or blockages and replace it as needed.
  • Confirm that the AC unit’s size is appropriate for your home since an oversized unit may cause short cycling.
  • Schedule a service call with Lane Heating & Air for a thorough inspection and AC repair in Lake City, FL.

Thermostat Malfunctions

A faulty thermostat can lead to significant issues with your AC system, such as not maintaining the correct temperature or not turning the system on or off at the right times. Moreover, this can result in discomfort within your home environment, as well as inefficiencies that increase operational costs over time.


  • Verify the thermostat’s settings to ensure it’s programmed correctly.
  • Swap out old batteries for new ones to guarantee the device works correctly.
  • Think about switching to a smart thermostat for enhanced efficiency and control. We specialize in thermostat upgrades and can provide expert advice and installation in Lake City, FL, and Gainesville.

Refrigerant Leaks

Refrigerant is essential for your AC unit to cool the air effectively. A leak can cause your system to underperform and can also harm the environment.


  • Schedule an AC repair in Lake City, FL with Lane Heating & Air to detect and seal any leaks.
  • Have the technician recharge the refrigerant to the manufacturer’s specifications.
  • Routine inspections can avert potential leaks and maintain your system’s optimal performance.

Dirty Condenser Coils

The condenser coils, located in the outdoor unit of your AC, release heat removed from your home. When these coils become dirty or clogged, the system has to work harder to cool your home, leading to increased wear and reduced efficiency.


  • Frequently tidy up the space surrounding the outdoor unit and clear away any debris to keep the coils clean.
  • Schedule a professional cleaning service for the coils with us to ensure they are cleaned properly without damaging the fins.
  • Incorporate coil cleaning into your annual AC maintenance plan to maintain optimal system performance.
