Direct Channels
Three ways to reach the Mitsubishi Electric building systems desk
Choose the channel that matches your stage. Early design teams usually start with capacity tables and ambient curves; late-stage teams send refrigerant pathway drawings and BMS point lists.

Dealer introductions within 2 business days on complete packages
Urgent commissioning questions submitted before 14:00 CT are triaged the same business day when a site contact and outdoor unit model are included.
When heat pumps outperform boilers—and when they need help
Project teams sometimes ask the contact desk to declare a universal winner between natural gas boilers and all-electric heat pumps. We will not. We will ask for outdoor design temperatures, envelope air permeability, and whether Hyper-Heating H2i capacity retention is required before recommending a topology. If your brief is innovation-led, bring BMS and smart-building goals. If it is performance-led, bring load calculations and refrigerant pathway constraints first.
The dark split form below routes either path to a specialist who will say when City Multi heat recovery is justified—and when a simpler ductless multi-zone package is the cleaner specification.
What to include in your inquiry
- Building type and zoning intent
- Heating/cooling design temperatures
- Preferred topology: ductless, H2i, or VRF
- BMS / thermostat integration needs
- Timeline, region, and dealer preference
Complete packages receive a topology recommendation with capacity table references and next-step dealer routing.
