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 in Whitby on Twintech Heating and Cooling

Very impressed with this company. They show up on time , kept my place clean and after they left it looks like they were never there. Very professional team. Those people know what they doing . Their installation was on the highest standard. They are very knowledgeable especially they're worker Peter. I strongly recommend this company to everybody. After the installation I receive the call making sure I'm satisfied with their products and their job. Bravo!!!

by James in Bowmanville on Twintech Heating and Cooling

Greg and his brother were referred to us by a friend. They arrived when they said they would, did an exceptional job and left the place as tidy or tidier then they found it. Their professionalism is only surpassed by their kind and friendly demeanor. Even after several calls to help me with my high tech thermostat I feel that I could always call with any concern (No one responds to my texts as quickly as Greg) and have a friendly helpful response. I found out their grandfather started the company and now as a 3rd generation company, they are doing their grandfather proud. I would highly recommend Twintech over any other hvac company out there.

by RJW in Ajax on Twintech Heating and Cooling

Thanks to the guys at Twintech Heating for a great job installing a new hot water tank. They set a time and day to remove the old tank and install the new one. They were on time and had the work done quickly and cleaned up after they were finished. Excellent work and great value.

by Marilyn in Milton on Twintech Heating and Cooling

In November, we contacted Twintech for a quote on a high efficiency furnace plus installation. Dave, the sales representative for the company was very friendly and informative. Upon arrival at our home, he willingly showed us his company licenses, clearly explained the operation of a high efficiency furnace and answered all our questions to our satisfaction. As well, Dave was the only sales representative that we contacted that was willing to make the arrangements for an energy audit. For us, this was a big plus as we found the government rebate program somewhat confusing to navigate. The furnace was installed on the date that was arranged in an efficient and professional manner by Greg (the owner) and Peter. Both men worked diligently, throughout a long day to complete the job and upon finishing, left the job site immaculate. When a neighbour raised concerns about the furnace venting location, Greg located an alternative location and resolved the situation with diplomacy. We chose the Napoleon furnace for its excellent warrant;y on the heat exchanger and because it was made in Canada! In addition, to the furnace warranty, Twintech offered us a 5 year warranty on labour which speaks to the quality and pride this team has in their workmanship. It has been over a month now (with some of the coldest January days on record) since we have had the furnace installed. The furnace runs quietly and distributes heat more evenly throughout our 90 year old Toronto home. We can't speak highly enough of the Twintech team and are very satisfied with their workmanship and job ethics. We have no hesitation about recommending them.

What more could you ask for! Grant and Greg Dainty provided a professional,diligent and thorough approach to the installation of my furnace. I would highly recommend there services.

by Hector in Scarborough on Twintech Heating and Cooling

Last week our Furnace failed overnight. We called Twintech to help us get it running again. They did a really thorough check on it, and got it running in less than an hour. Given that it was an old Furnace (+20 years old), we were giving two options: repair it or replace it. Instead of doing a repair on it that could break in a week or two, they recommended us to change it. I like that they were honest on the recommendation, not forcing a new furnace on us. At the end we went with a new Furnace. Twintech solutions service & salesman gave us recommendation on the size of the unit and many options that could work for our home. They ended up doing an excellent work in our furnace, replacing the filter to a better option and replacing some pieces that had water damage. They cleaned after themselves and leave everything even better than what they found. They even went far and beyond tiding up the hose connections that we had on the basement.

by Ryan Doherty in Whitby on Twintech Heating and Cooling

I am in the process of finishing my basement and wanted to make sure I got the low hanging duct work fixed in advance. After reviewing 5 quotes I selected Twintech to award the contract to. The price was competitive however what won me over was Grant's (co-owner) attention to detail and his ability to focus on what my goals and priorities were for the project. His team completed the job over 3 days as there was significant duct work changes and the relocation of all of the equipment. They also completed the job with little downtime so we weren't left overnight without heat during freezing winter temperatures.

My father woke up to no heat one Saturday morning. We had a few names that friends had recommended but while checking out the companies' ratings on HomeStars, we found Twintech with great ratings too. The other companies either didn't get back to us or didn't have time to come at such short notice. TwinTech made the time in their schedule for what they judged to be an emergency: no heat in the home of an elderly person. At no extra fee for a short notice, weekend visit. They recommended an upgraded furnace unit and explained that we would qualify for a rebate that would bring the price down to that of a lower model. They set us up with the rep from the MNR that covers the rebate so that we didn't have to deal with the paperwork & phone calls ourselves. Installation was quick, efficient, & smooth. We were so pleased with their service we ordered a new water heater too. Both are working great (efficient & quiet!) & my father is safe & comfortable. We can't say enough about how pleased we are with their service. We have already recommended them to others.

by joe calabro in Pickering on Twintech Heating and Cooling

Twintech Heating & Cooling. I just want to say thanks for helping me . My Furnace stopped working. And l phone Dave Getgley he set me up with Greg. What an amazing team they did a great job in setting me up with a new Furnace. Anyone that needed a new Furnace these are the guys to call. Thanks again for a job well done.

by Peter from Ajax on Twintech Heating and Cooling

Our home has had poor heating and air conditioning the past couple of years. Dave recommended a Goodman solution with more power than we had. Grant and Greg installed the units in late November. Heating is better than ever. We have a warm home again and look forward to the winter. Can't wait to see how the AC runs in 2018. Job was super clean and professionally done. Highly recommended.

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 Robert Rogers on Twintech Heating and Cooling

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.

by Robert Mizuno on Twintech Heating and Cooling

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!

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!
