Common Ways Your AC Might Break Down
Posted On: May 18, 2024
Air conditioning systems are essential for maintaining comfort in hot weather, but they can encounter various issues that lead to breakdowns. Understanding the common causes of AC failures can help you take preventive measures and ensure timely repairs. Here are some of the most frequent ways an AC might break down:
1. Refrigerant Leaks
Refrigerant is crucial for cooling the air. If there's a leak, the AC won't cool properly and may even freeze up. Low refrigerant levels can also damage the compressor, leading to costly repairs.
2. Dirty or Clogged Filters
Filters trap dust and debris to keep the air clean. When they become clogged, airflow is restricted, causing the system to work harder and potentially overheat. Regularly replacing or cleaning filters is essential to maintain efficiency.
3. Thermostat Issues
A malfunctioning thermostat can cause your AC to turn on and off irregularly or fail to maintain the set temperature. Problems can range from simple calibration issues to complete failure of the thermostat unit.
4. Electrical Problems
Electrical issues, such as faulty wiring or tripped circuit breakers, can prevent the AC from operating. Electrical problems can also lead to more severe issues, like compressor and fan motor failures.
5. Frozen Evaporator Coils
Evaporator coils need warm air circulating around them to function correctly. When airflow is obstructed, typically due to dirty filters or blocked ducts, the coils can freeze, causing the AC to stop cooling effectively.
6. Condenser Coils Problems
Condenser coils, located in the outdoor unit, can become dirty over time due to exposure to the elements. Dirt and debris on the coils reduce their ability to release heat, causing the system to overheat and fail.
7. Fan Issues
Both the blower fan (inside) and the condenser fan (outside) play crucial roles in cooling your home. Problems such as worn belts, motor issues, or debris buildup can hinder their operation, reducing the system's efficiency or causing it to shut down.
8. Drainage Problems
The condensate drain line removes moisture from the air. If it becomes clogged or the pan overflows, it can lead to water damage and increased humidity levels. In severe cases, it can trigger a system shutdown.
9. Compressor Failure
The compressor is the heart of the AC system, responsible for circulating refrigerant. It can fail due to electrical issues, overheating, or low refrigerant levels. Compressor failure often requires a costly replacement.
10. Sensor Problems
AC units have sensors that detect room temperature and control the cooling cycle. If a sensor is knocked out of position or malfunctions, the AC may cycle constantly or behave erratically.
11. Ductwork Issues
Leaky or poorly insulated ducts can cause cooled air to escape before it reaches your living space, making your AC work harder to maintain the desired temperature and increasing wear and tear.
12. Lack of Maintenance
Routine maintenance, such as cleaning coils, checking refrigerant levels, and inspecting components, is essential to keep an AC unit running smoothly. Neglecting maintenance can lead to the accumulation of minor issues that eventually cause major breakdowns.
Conclusion
Regular maintenance and prompt attention to minor issues can prevent many common AC breakdowns. By understanding these common problems and their causes, you can take proactive steps to extend the life of your air conditioning system and ensure it operates efficiently when you need it most.

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.
There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.
Jul 14, 2024
I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.
