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.

See What Our Customers Are Saying:

by Nancy H. from Oshawa on Twintech Heating and Cooling

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.

by Syd from Whitby on Twintech Heating and Cooling

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.

by jenner iksmom from Oshawa on Twintech Heating and Cooling

Very polite and professional. They removed my o
ld furnace and A/C and installed my new ones. They were efficient and thoroughly cleaned up when they were done! I would highly recommend them!

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.

by Kate A in Pickering on Twintech Heating and Cooling

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.

by Private User in Whitby on Twintech Heating and Cooling

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

by Private User from Bowmanville on Twintech Heating and Cooling

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.
