Tried AC for the first time this year and it won't get cold
Posted On: July 22, 2023
I have a window unit AC from Walmart that I only have installed for a month or two in the summer.
Never had any issues.
I installed it last night and ran it all night, it never got cold.
I tried cleaning the filter, messing with the temp knob on the front, nothing.
Basically it's just a fan right now.
I hear the "whine" of what sounds like a compressor kicking in but no cold air.
Is this something I can troubleshoot? If not and I have to buy a new unit, is this worth anything on craigslist for parts or repair?
Question from user ShabazzCBD at AirConditioners at reddit.
It sounds like there might be an issue with the cooling system of your window unit AC. While there are a few things you can try to troubleshoot the problem, keep in mind that working with electrical appliances can be dangerous, and if you're not comfortable or experienced in doing so, it's best to contact a professional technician for assistance. However, here are some basic troubleshooting steps you can attempt:
-
Power and settings check: First, ensure that the unit is receiving power and that the settings are correct. Make sure it's plugged in properly and that the temperature and mode settings are appropriate for cooling.
-
Clean the coils: Dust and debris can accumulate on the condenser coils, hindering the unit's cooling efficiency. Turn off the unit, unplug it, and carefully clean the coils with a soft brush or vacuum cleaner.
-
Check for ice buildup: Sometimes, excessive ice buildup on the evaporator coils can block airflow and prevent cooling. If you suspect this is the issue, turn off the unit and let it thaw completely before trying again.
-
Inspect the compressor and fan: If you're comfortable with basic electrical troubleshooting, you can inspect the compressor and fan for any visible damage. Ensure that the fan is spinning freely and that there are no loose or damaged wires.
-
Check the refrigerant: Low refrigerant levels could be the cause of the AC not cooling properly. However, refrigerant handling requires specialized equipment, so it's not something you can easily do yourself. A professional technician will need to check the refrigerant levels and recharge the system if necessary.
If none of these troubleshooting steps work, and you're not able to fix the issue yourself, it might be time to consider getting a new unit. As for selling the non-functioning unit on Craigslist, there might be some people who are interested in buying it for parts or repair. However, don't expect to get a high price for it, as it's not functioning correctly. Be honest about the issues when listing it for sale.
Before disposing of or selling a broken unit, consider checking if there are any local recycling or electronics disposal programs available. It's always best to dispose of electronic devices responsibly to minimize environmental impact.

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

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!!

Bob, Greg & Mitch make a great team! Quick appointment times, super knowledgeable, expert troubleshooting capabilities & very customer service oriented.
I would highly recommend them for all of your HVAC needs! Great job guys!!

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!

Just had a new furnace installed by Twintech. I cant express how great these guys are at what they do. From the sales to installation they were professional all the way. Very reasonable pricing and courteous during the installation and willing to answer any questions I had. Highly recommended !!!

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.
There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

Highly recommend Twintech Heating company, we got honest and detailed information on what was needed to replace and install a new gas furnace. Bob and Greg made us feel comfortable withe process through their thorough explanation and knowledge of the right furnace for our needs. The professionalism and courteous friendly attitude towards the customer is what we liked the most as they treated us like family. So happy with our decision and new furnace we will be looking into get our rental water heater replaced and installed by Twintech team. We feel better having their knowledge on our side and will only trust them with any further maintenance of furnace.

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.
