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:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
We are very happy with our new furnace. The service was excellent the guys worked 6 hours straight through and there was no mess at all they took the old furnace boxs etc with them they then explained everything to us they were very helpful and pleasant , when we need a new air conditioner we know who to call!
The crew from sales to installation was very professional and had great attention to detail
We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!
We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.
We were very pleased with every aspect of the work that was done. They were very professional and polite. They arrived when they said they would and job was completed on estimated time
We would highly recommend them to whoever needed a recommendation
We have a very large dog and they were very understanding and respectful of him being around
The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.
The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.
Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!
I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.
Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons
Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.
We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.

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.
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!
Very pleased with the professional service that TwinTech Heating and Cooling provided in replacing my furnace. I got several quotes from different service providers. Their price was excellent and they explained the features very well. We are very glad we went with TwinTech and highly recommend their services.
We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!
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!
