Common Ways Your AC Might Break Down

Common Ways Your AC Might Break Down

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.

by Peter, Pickering on Twintech Heating and Cooling

On coldest night of the year our furnace quit. At 8:40 in the morning Greg arrived and gave us a diagnosis and a recommendation. By 2:30 we had a new furnace and were warm again. Great company. Great customer service. Good reasonable price.

Twin tech team was very efficient and prompt. They provided a quote within hours of request and got the job done on time. No disruption to home function. We would highly recommend this team. Job well done.

by John from Toronto on Twintech Heating and Cooling

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

by Ryan k on Twintech Heating and Cooling

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.

The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

by Louise in Scarborough on Twintech Heating and Cooling

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.

by Private User on Twintech Heating and Cooling

Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

by Private User on Twintech Heating and Cooling

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.

by Private User on Twintech Heating and Cooling

This is a professional team that's easy to deal with. I would strongly recommend them

by hj.taggart in OSHAWA on Twintech Heating and Cooling

Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

by susieschoeppler in Oshawa on Twintech Heating and Cooling

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
