For more than 12 years, Sandra Brue and husband Chris Carstens struggled with hot and cold spots in their San Diego penthouse. A Variable Refrigerant Flow zoning system from Mitsubishi Electric put an end to these troubles, coupling with the existing geothermal loop to provide even temperatures throughout the home. A bonus: VRF recovered four to six inches of ceiling height, giving the home more visibility and an even roomier feel. Download the PDF below to read more. You’ll hear from the homeowners and contractor, and see photos of the equipment and home.
