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.

We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.
The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.
Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.

We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.
