Frequently asked questions.
How many rooms can the Cooper & Hunter 2 Zone 18,000 BTU mini split cool?
The Cooper & Hunter 2 Zone 18,000 BTU system is designed to effectively cool up to 850 sq ft, which typically accommodates 2-3 rooms depending on layout and insulation.
Can I mix BTU sizes in a mini split system?
Yes, you can mix BTU sizes in a mini split system like the Cooper & Hunter 2 Zone, provided that the total capacity does not exceed the system's 18,000 BTU limit. This allows for tailored cooling solutions based on specific room needs.
Do all zones in the Cooper & Hunter 2 Zone system run simultaneously?
In the Cooper & Hunter 2 Zone system, both zones can operate independently, which means they do not necessarily run simultaneously. This feature allows for customized comfort in each zone based on individual preferences.
Is the Cooper & Hunter 2 Zone mini split efficient compared to multiple single-zone units?
With a SEER rating of 19.0, the Cooper & Hunter 2 Zone mini split is more energy-efficient than running multiple single-zone units, which typically have lower ratings. This efficiency can lead to significant savings on energy bills over time.
What are the warranty terms for the Cooper & Hunter mini split?
The Cooper & Hunter mini split comes with a 5-year parts warranty and a 7-year compressor warranty, but registration is required within 30 days of purchase to activate these terms.
Does the Cooper & Hunter mini split come pre-charged with refrigerant?
Yes, the Cooper & Hunter mini split is pre-charged with R454B refrigerant for up to 25 ft of line set, making installation easier and ensuring optimal performance right out of the box.
