So, what does NOOF air conditioner actually mean?
NOOF air conditioner is based on an acronym. NOOF means Never Out Of Fashion. However, installing HVAC in an old home with the latest HVAC is impossible. Because those houses don’t have FA/CAC vents. So, the ductless air conditioner with the latest technology is termed a NOOF air conditioner.

Frequently Asked Questions (FAQs)
How Can You Detect a Defective Blower Motor?
The easiest way to figure out a defective blower motor is by observing the airflow. There would be little to no airflow from vents. Due to the blower overheating, odd odors could be detected. The cost of electricity will likewise soar. Also, the condenser may perform well but AC won’t cool.
Which Thermostat Do You Need for Your Air Conditioner?
The thermostat that matches the voltage of your AC is required. Also, check the compatibility of both. A higher voltage thermostat can control the temperature of the basement. Whereas, low voltage thermostats work for upper stories. Choosing an incompatible thermostat can greatly hinder efficiency.
Why Is Your Air Conditioner Not Cooling Properly?
Your AC may not cool properly to a blocked condenser coil. It may gather heaps of dirt or debris. Hence, air cannot properly get through it. As a result, it isn’t cooling like before. Cleaning that dirt and debris can restore the proper cooling function. Otherwise, you need to add compressor gas.
