Questions
Frequently Asked Questions
- How efficient are ductless mini-splits?
- Very. Because there are no ducts (which can lose 20–30% of conditioned air) and each zone has its own thermostat, ductless systems are among the most efficient ways to heat and cool a home.
- Are ductless mini-splits quiet?
- Yes. Indoor units typically run at 20–30 decibels — about the level of a whisper. The outdoor unit is also much quieter than a traditional central AC condenser.
- Can a ductless system heat my home in winter?
- Yes. Modern ductless systems heat and cool. In the Upstate climate, a ductless heat pump handles heating efficiently for most of the winter, with very low operating costs.
- How many indoor units can one outdoor unit support?
- Most residential outdoor units support up to 4–5 indoor units, each with its own thermostat. so you can control the temperature in every room independently.
- Do you offer emergency ductless repair?
- Yes. We offer 24/7 emergency repair service. After-hours and emergency calls may include a modest service fee, always explained in advance before any work begins.
