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.

A dear late cousin of mine recommended this company and I have been happy with the service.

We are very pleased with the work done by Twintech. They were very professional from start to finish. Dave came to our home and gave us a very competitive quote for new high efficiency furnace and air conditioner. The installers were very courteous and professional. We would highly recommend them.

Great experience getting an old furnace replaced.

This review is late coming so my apologies to the amazing Twin Tech team! I contacted Dave at Twin Tech for a quote this past Feb (as I was collecting a few) and his recommendation was excellent. From the first meeting with Dave to the team installing the new furnace, not once did i feel uncomfortable . The team were extremely professional yet personable and clean and tidy. Decent companies still exist!
The new furnace just purrs and its just amazing the difference it has made!
(PS my sibling ended up getting a furnace from them as well)

The service was Twintech was excellent.
Dave our salesperson was easy to talk to and was professional. The unit recommended meets our needs and budget.
Greg and his team arrived on time for the installation and even got rid of the garbage the contractors left in our furnace.
Would definitely recommend Twintech.

Our old water tank was installed in 1997. Wasn't working as well as it should so we looked into a tankless as it is more efficient and a space saver! we had used Twintech in the past for a furnace cleaning and were satisfied with that so we decided to ask for a quote for the changeover. Gary arrived and provided the options and the quote fit within our budget so we decide to go with them after receiving a few alternative quotes from other companies. They did what the said would be done and it was completed within a reasonable time frame! Removal and cleanup of the old tank was seamless. We are now enjoying consistent and efficient Hot water! I recommend Twintech and would use them for future projects!

by New AC Unit + Humidifier on Twintech Heating and Cooling

One of the most honest HVAC companies out there! Dave was very helpful and informative in helping us choose a new AC unit. While they weren’t the lowest quote, we went with them because we trusted Dave and he was the most honest guy out of the companies that quoted us.
Greg and his crew who installed the unit were very professional and did a great job. If I could do it over again I would choose Twintech again.

by Private User on Twintech Heating and Cooling

Relocated and replaced our air conditioning unit. Fast, professional, and high quality service. We would definitely use them again for future projects!
