Hello!.
My TURBRO 8000 BTU air conditioner is no longer cooling my room effectively.
My exhaust tube is about 8 feet long, but I don't think that's the main problem.
It was cooling my room effectively before, down to 74 when it was 85 outside and humid.
The unit still blows cool air, and I have better results when I put it on dehumidifier mode.
Any thoughts would be greatly appreciated.
Question from user Ace888281 at AirConditioners at reddit.
Answer:
There are several possible reasons why your portable air conditioner is no longer cooling your room effectively.
Some of these reasons are: Dirty air filter: A dirty air filter can reduce the airflow and cause the unit to work harder to cool the room.
This can lead to poor cooling performance.
Check the air filter and clean or replace it if necessary.
Low refrigerant level: If the refrigerant level is low, the air conditioner may not be able to cool the room effectively.
This is typically a problem that requires professional repair.
Blockage in the exhaust hose: If the exhaust hose is blocked or has a kink, it can reduce the airflow and cause poor cooling performance.
Make sure the exhaust hose is free from any obstructions and is not bent or kinked.
Heat load in the room: If the room has a high heat load, such as from electronic devices or direct sunlight, the air conditioner may struggle to cool the room effectively.
Try reducing the heat load by turning off unnecessary electronics or closing curtains and blinds.
Ambient temperature and humidity: The air conditioner may struggle to cool the room effectively if the ambient temperature and humidity are very high.
This is because the unit has to work harder to remove the heat and moisture from the air.
Try using the air conditioner in a smaller, more enclosed space or consider adding a second unit to help cool the room.
Based on your description, it seems that your air conditioner is still blowing cool air and works better on dehumidifier mode, so it's possible that the problem is not with the refrigerant level.
You may want to check the air filter and exhaust hose first, as these are more easily accessible.
If the problem persists, it may be best to contact a professional for repair or further diagnosis.

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!

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!!

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!
