When temperatures start to change drastically, you want to be certain that your air conditioner and heater are up to the job of keeping your home at the optimal temperature.

Common Causes of Air Conditioner Breakdowns

Are your air conditioning blues getting you down? Don't worry, you're not alone. Believe it or not, air conditioners are complicated machines. With the help of modern technology, they can keep your home cool and comfortable all year round. But, like any mechanical system, they can sometimes break down. Below is a list of the most common causes of air conditioner breakdowns to help you identify potential issues before they turn into costly repairs.


  • Leaking Refrigerant : This is one of the most common causes of air conditioner breakdowns. If your air conditioner is leaking refrigerant, it will not be able to produce cold air efficiently. If you’ve noticed that your air conditioner is not able to reach the desired temperature or that the air coming out of the vents is warmer than it should be, you should check for leaks.



  • Dirty Condenser Coils : The condenser coils of your air conditioner are responsible for releasing heat, which helps cool your house. If these coils become dirty, the air conditioner will not be able to cool your home properly. To keep your air conditioner running smoothly, make sure these coils are cleaned regularly.

  • Blocked Vents : This is a common problem in older homes or when furniture is placed too close to the air conditioner vents. Blocked vents can lead to inefficient cooling, as the air conditioner will struggle to push the air out. If you notice that your air conditioner is not producing enough cold air, check to make sure all of the vents are free from obstructions.


  • Clogged Drain Line : If your unit isn’t draining properly, water can build up and cause your AC unit to malfunction. To prevent this, make sure the drain line isn’t clogged with dirt, dust, or debris.


  • Worn-out AC Components : Over time, components such as the condenser fan motor and capacitor can wear out. This can lead to your unit not being able to run properly, which can cause it to break down.



Common Causes of Heater Breakdowns

Is your home’s heater acting up? Don’t let the winter chill cool down your spirits - it’s important to learn the common causes of heating system breakdowns. From dust accumulations to faulty thermostats, here are some of the most common causes of heater breakdowns. 


  • Furnace Malfunction : The furnace is a major component of your home’s heating system, and it can malfunction due to various reasons. Common issues include a lack of proper maintenance, faulty wiring, and a build-up of dust and debris. A malfunctioning furnace can cause uneven temperatures or no heat at all.


  • Dirty Air Filters : Air filters are essential for keeping your home’s air clean, but over time they can become clogged. When this happens, the airflow to your heater will be restricted, decreasing its efficiency. Make sure you change the filter as often as necessary to avoid this issue.

  • Faulty Thermostat : The thermostat monitors the temperature of your home and signals the heater to turn on and off when necessary. If the thermostat is malfunctioning, your heater will not be able to heat your home correctly. Check for issues such as faulty wiring, incorrect programming, or a malfunctioning thermostat.


  • Dust Accumulatio n: Over time, dust and debris can accumulate inside your heating system, restricting airflow and blocking heat exchange. This can result in the unit not working as well as it should or failing altogether.


  • Outdated Unit : If your heating system is older, it might be time to upgrade. An outdated unit will not likely last long and is more likely to break down under the strain of extreme temperatures.


  • Electrical Issues : Loose wiring, burnt-out fuses, and other electrical malfunctions can prevent the unit from working correctly. This can lead to short circuits, fire hazards, and even complete system failure.


 By being aware of the common causes of air conditioner and heater breakdowns, you can make sure your home is prepared for any temperature changes. If you notice any issues with your heating or cooling system, contact a professional technician to get it serviced and back up and running quickly.
