Frequently Asked Questions
How does the EasyPro® compare to the DIY Select and DIY 5th Gen?
The EasyPro® sits between the two. It has a higher SEER2 (20.0) and better warranty (5-yr compressor / 3-yr parts) than the DIY Select, but a shorter warranty and lower SEER2 than the premium DIY 5th Gen (which offers 7-yr compressor and Energy Star certification). It’s the best value for buyers who want more than entry-level without paying full premium price.
Does this unit require special wiring?
Yes — the EasyPro® 18K runs on 208-230V and requires a dedicated 230V circuit. A licensed electrician is recommended for the electrical hookup.
What suction line size does this unit use?
This unit uses a 1/2" suction line. The included 11.5 ft. line set is pre-sized for this unit. If you need a longer run, make sure any additional line set uses 1/2" suction.
What is the minimum cooling temperature?
The EasyPro® 18K cools down to 5°F outdoor temperature. For heating, it operates down to -13°F. If you need cooling in extreme cold climates, consider the DIY 5th Gen or Hyper Heat instead.
Is it Wi-Fi compatible?
Yes. Control your system from anywhere using the MRCOOL Smart HVAC Controller® app on iOS or Android. It also works with Amazon Alexa and Google Assistant for hands-free voice control.
What is the warranty?
The EasyPro® is backed by:
- 5-Year Compressor Warranty
- 3-Year Parts Warranty
