Is My AC Unit Defective?

If you suspect your AC unit is defective, there are a few steps you can take to troubleshoot before concluding it's faulty:


Check the settings: Ensure that the thermostat is set to cool and the desired temperature is lower than the current room temperature.


Inspect the air filter: A dirty or clogged air filter can restrict airflow, causing your AC unit to work harder and less efficiently.


Replace or clean the filter if necessary.


Check the circuit breaker: Make sure the circuit breaker for your AC unit hasn't tripped.


If it has, reset it and see if that resolves the issue.


Inspect the outdoor unit: Ensure that the outdoor unit is free of debris such as leaves, dirt, or grass clippings.


Restricted airflow around the unit can hinder its performance.


Listen for unusual sounds: Strange noises like grinding, banging, or squealing could indicate a mechanical issue that requires professional attention.


Feel the air coming from the vents: If the air isn't as cool as it should be, or if there's weak airflow, there could be a problem with the compressor or ductwork.


If you've gone through these steps and your AC unit still isn't functioning properly, it may indeed be defective.


In such cases, it's best to contact a professional HVAC technician to diagnose and repair the issue.


They can provide a comprehensive assessment and recommend the appropriate course of action.

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed…They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

by Damien McIsaac. Ajax on Twintech Heating and Cooling

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

by Blair N. - Toronto on Twintech Heating and Cooling

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

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!

by Anna Chin on Twintech Heating and Cooling

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

by Connor Agnew on Twintech Heating and Cooling

Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
