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 first met Greg and Grant (The Twin Brothers from Twin Tech - yup -it's not just a cool company name) back in 2014 when our furnace broke down and they installed our Carrier Furnace and AC that we purchased through Sears. I liked them instantly when I met them due to their friendly and professional service, and the fact that they didn't mind taking a little extra time to explain things in terms I could understand. Since that time they have reached out to me at least once a year to ensure that everything was running smoothly with my system and to keep me appraised of their evolving services. Due to this high level of proactive customer service I didn't hesitate to call and obtain their help for a Gas Stove removal and installation. When I scheduled the call Greg and Grant let me know that they would arrive the morning of the appliance delivery to disconnect the old gas stove, and then return in the afternoon to connect the new stove. Sure enough, they did just that as promised. Where they exceeded my expectations is with the extra level of support helping to assemble the burners and grills on the stove and in the oven. This may seem like a small thing to some but to my wife who was at home during this entire process it meant a stress free transition to the meal prep for the day. When I called home to ask about the install she commented that, "they left the place cleaner than it was when they arrived and they setup all the grills on top of the stove and in the oven... they didn't have to do all that -Wow!". You know what they say, Happy Wife, Happy Life. So in summary, I am recommending Twintech Heating & Cooling for all of your Furnace, Air Conditioning, and Gas Line needs. I've even called on these guys to help swap out a leaky water valve. They are just so easy to reach and communicate with by phone, and they don't mind a text message to confirm the details. You can rest easy when you have the Twins on your side as an extension of your household maintenance plan.

First thing, they actually showed up for a quote. Other big name companies in the area didn't even return my call , job was done as expected and new equipment is quiet and installed very clean and professional. Would highly recommend these guys.

They removed our old furnace and replaced it with a new furnace and AC system.

Work was performed in a clean and timely manner. The furnace and metal work was performed by the Twintech team (did not require separate contractor to do the metal work). Energy audit was arranged and promised rebates were received. The overall price was very competitive. We have recommended Twintech to several of our friends and family. Awesome job.

Grant and Greg installed a heating and AC system in our new Linwood post and beam home. Post and beam can be challenging structures for running ductwork and their high ceilings and open concept frequently frustrate efforts at balancing air flow and controlling temperatures. But these guys did it and did it right the first time. Even the building inspector was impressed with what he saw. More importantly, the boys brought a high degree of trust and integrity to the job. Something in short supply these days.

I have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.

I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.
