Is my new Window AC defective?

I'd be glad to help you troubleshoot whether your new Window AC is defective.


Here are some troubleshooting tips you can follow to determine the issue:


No Cooling or Weak Cooling: Ensure that the temperature settings are correctly adjusted.


Check if the AC's cooling mode is active and not set to just fan mode.


Make sure the air filter is clean and not clogged, as a dirty filter can reduce cooling efficiency.


Verify that the AC is properly sized for the room.


An undersized unit might struggle to cool effectively.


Strange Noises: Some level of noise is normal, but if you're hearing unusual or loud noises, it could indicate a problem.


Rattling or clicking sounds could be due to loose parts.


Make sure all panels, grills, and components are securely attached.


Squealing or grinding noises might indicate a problem with the fan motor or other moving parts.


Water Leakage: A small amount of condensation or water near the unit is normal.


However, excessive leakage can indicate a problem.


 Check if the drainage system is functioning properly and not blocked.


Electrical Issues: Ensure that the AC is properly plugged in and receiving power.


If the AC keeps tripping the circuit breaker, there could be an electrical issue or the unit might be overloading the circuit.


Remote Control or Panel Issues: If the AC is operated using a remote control, check if the batteries are functional and properly inserted.


Make sure the control panel on the AC unit itself is responsive and not displaying any error codes.


Odors: New AC units might have a slight odor initially, but persistent or foul smells could indicate mold or other issues.


Clean or replace the filter and ensure proper ventilation.


Insufficient Airflow: Check if the air vents and filters are clean and unobstructed.


Ensure that curtains or furniture are not blocking the airflow from the AC.


Temperature Inaccuracy: Use a separate thermometer to check if the temperature displayed on the AC matches the actual room temperature.


Remote Control Problems: If the remote control isn't working, try replacing the batteries and ensuring there are no obstructions between the remote and the AC unit.


If you've gone through these troubleshooting steps and the issues persist, or if you're unsure about performing any of these steps, it's advisable to contact the manufacturer's customer support or a professional technician.


They can provide further guidance and assistance based on the specific model of your Window AC.

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

by Trevor Owens on Twintech Heating and Cooling

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. I’ve used the company in the past for my furnace so I was happy when I recognized Greg at my front door. He’s great and the service is always top notch. I’d highly recommend using twintech for honest, superior service in the Durham region. Thanks!

by Nicole Alain on Twintech Heating and Cooling

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!

I would highly recommend them for all of your HVAC needs! Great job guys!!

by Jacqueline Graham on Twintech Heating and Cooling

Twintech Heating & Cooling installed my furnace in 2022 and in fall of 2023 installed my Panasonic Heat Pump. Greg and Mitch did a great job. Helped me through the rebate process. Super happy with the Heat Pump. Only used my furnace 5 times this winter. Energy bills lower, carbon emissions lower.Thank you Twintech. I recommend highly!
