The short answer to the question of “Can I fix My AC Unit Myself?” is that you probably could but should not attempt any do-it-yourself repairs with a central air conditioner. The contemporary air conditioner is air to heat systems that are complex pieces of refrigeration technology, and even the most basic repairs require years of experience and specialized tools. Amateur staff can’t fix motors, close refrigerant leaks, or recharge refrigerant. Additionally, even correctly diagnosing a problem to determine what has to be corrected is difficult.

However, if your air conditioner isn’t operating properly, you may take some precautions to ensure it isn’t a basic problem that doesn’t necessitate the services of a professional. These aren’t precisely repairs, but they could save you time calling a repairman.

  • Check and replace the air filter: This is the most fundamental step in dealing with an air conditioner that is unevenly cooling, producing low airflow, or tripping circuit breakers. The filter in the HVAC cabinet acquires dust as it runs throughout the months, and the dust finally clogs the filter so severely that it obstructs the passage of air. Every one to three months, we recommend changing the filter. When the air conditioner fails, replace the clogged filter.


  • Examine the thermostat: It may seem strange to mention this, but sometimes the problem is as simple as wrong thermostat settings. Someone may have altered the software. If you have a heat pump, it may have been mistakenly turned to heat rather than cool.


  • Tripped circuit breakers must be reset: If the air conditioner’s fans or compressor would not start, check the electrical panel to see if any circuit breakers have tripped. A tripped breaker may result from a momentary overload caused by the AC starting up. Reset the breaker and test the air conditioner. If the circuit breaker trips again, a specialist must fix it.

The Condenser.

  • Clean the outside cabinet: Dirt and obstructions on the exterior cabinet may be the cause of low air conditioner cooling power (the condenser). If the condenser is unable to transfer enough heat to the outside, it will be unable to collect enough heat from within. Brush the cabinet down and remove any impediments (leaves, branches) that are too close to it.

Room Ventilation

  • Check that the room vents are open: Closing room vents will not help you conserve energy! It raises the pressure in the air conditioner, which might harm it or force it to shut down prematurely. Check sure all of the room vents are open and that nothing is blocking them. Please contact us if you are still experiencing AC issues. We are concerned with your comfort.
