My AC Unit is Not Working, What Now?

You may encounter many problems with your air conditioner and while it is true that most problems require HVAC experts to repair them, there are some troubleshooting tips that can help homeowners fix the simple issues.


Here is a troubleshooting guide that can help you address some of the most common problems you may experience with your air conditioner:


Your AC Unit Won’t Turn On


If your AC unit is not turning on, check first your outside unit to determine if the condenser is running. Check if the unit is plugged in and your thermostat is set properly. Some thermostats are tricky so homeowners can save themselves time and money just by reading the manual.


Once you’ve checked the condenser, the plug, and the thermostat and it still isn’t turning on, check to see if there is a blown fuse or a tripped circuit breaker. If you do find frozen coil or if the unit is still not turning on, there might be a problem with the motor or the compressor. One of our HVAC experts can repair your system for you.


Your AC Unit is Not Cooling the Air


If your AC unit is turning on and the thermostat is set properly but it is not cooling, there could be a dirty or blocked air condenser. The first thing you can do is check the unit outside and clean its surroundings. If there is any debris or weeds that block the air circulation, remove them.


You also need to check your filter as it might be dirty. When the filter is dirty, it restricts the air to the evaporator coil, leading to a frozen coil. If you use your AC unit often or if you have pets, you might need to change your filter more often. You can pull out your filter and check if you can see through it. If you can’t, then it is dirty.


In some cases, an AC unit that is not cooling the air might have some problems with the compressor or refrigerant. Our HVAC experts can help you fix this issue.


Your AC Unit is Not Cooling Your Home Adequately


If your AC unit is on and set properly but it is not cooling your home adequately, you might have a unit that is not suited best to the size of your home. It is essential to have a system that is sized appropriately for your home to be able to keep your home cool on a hot day.


If this is the case, you might have a problem with the charge or there might be a frozen evaporator coil. If you can see icing on your outdoor unit, turn off your AC unit and call us immediately.

by Anna Chin, Ajax on Twintech Heating and Cooling

On one of the coldest days of winter, our furnace stopped working. Our regular furnace company came and told us we had a CO2 leak and shut us off. Their quote for a new furnace was way too high and they couldn't even install it on the same day. TwinTech was recommended to us by a friend. We called and spoke to Dave who was very nice and knowledgeable. Grant showed up a short time later and a new furnace was installed the same day with no troubles at all. Best of all, we received a higher-end furnace than what was offered by our previous company and at a cheaper price. I would recommend TwinTech with no hesitation at all.

by Hiba, Pickering on Twintech Heating and Cooling

I installed a new furnace and Air conditioner with them. The installation is of high quality and according to standards. The guys are professional and reasonably priced.. I highly recommend them.

by Robert, Pickering on Twintech Heating and Cooling

Had new furnace installed and ran into some difficulties but the contractor responded in a timely and efficient manner - after further service calls were made, a reasonable resolution was found.

by Brian Burns, Whitby on Twintech Heating and Cooling

The work was done quickly efficiently neatly and professionally. Pleased with the service, information, product, and the company.

by Geoff, Port Perry on Twintech Heating and Cooling

Great sales member named Dave came in told us some amazing items and how they would be priced installed an all. We couldn’t believe it! The next day the ac was installed, that day one employee named Greg told us that our furnace was working way to hard and was causing us to use way too much gas. So two days later they came in an installed a new furnace!

by MB, Ajax on Twintech Heating and Cooling

Installation was done quickly and professionally. The new furnace is quiet and provides even heat.

by Richard from Oshawa on Twintech Heating and Cooling

They removed and discarded old furnace. Installed new furnace. Installed air intake pipe, that had never been installed by builder, no charge. Replaced loose hose on floor with hard pipe and rerouted it to drain, no charge. Almost 33% cheaper then quote from Enercare, which was the company we dealt with and had insurance with for 8 years. No yearly fee for cleaning/insurance, saves 300 a year. Courteous, professional, fast, and friendly. My wife and I have been recommending them to everyone we know and meet, and will continue to do so. Thanks for everything, Twintech!!!

by Darcy from Pickering on Twintech Heating and Cooling

This company was great to deal with. Our furnace went down and they installed a new furnace the next day with a lot of professionalism!

by gillian hooton from Uxbridge on Twintech Heating and Cooling

Finally! An honest company with highly knowledgeable and informative staff. Had a furnace service and found multiply errors in our system from an amateur installer. Very fair price to correct problems and will definitely use again.

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!
