- Neat line-set routing and low-profile outdoor placement
- Full commissioning, documentation & inspection support
Multi-zone Mini-Split — from $13,000
10-year parts & labor warranty available. Great for 1–2 bedroom ADUs or when you want separate comfort zones.
- Room-by-room sizing and zoning
- Quiet indoor heads matched to room use
- Aesthetic placement to pass plan review and inspection
- Commissioning report for your records
Permits, testing, and a smooth final
- 1) Plan review: We review architect drawings and perform load calcs.
- 2) Design & equipment: We choose efficient, low-noise equipment sized to each room.
- 3) Permitting: We pull the HVAC permit and schedule inspections.
- 4) Installation: Clean routing, tidy exterior, and sealed penetrations.
- 5) Commissioning: We test and document performance for your occupancy sign-off.
Aesthetics matter
We route line-sets where they disappear, set outdoor units on clean pads or stands, and select indoor heads that compliment the space. Quiet, efficient, and good-looking.
ADU HVAC FAQs
Do you handle permits and testing needed for the ADU occupancy certificate?
Yes. We pull the HVAC permit, coordinate inspections, and complete any required functional and airflow testing so your ADU passes final.
How do you choose the right size and equipment?
We design from your architect’s plans and perform load/room-by-room sizing. We look at efficiency (SEER/HSPF), sound (decibel ratings), and line-set routing to avoid aesthetic issues.
What’s included in your $6,500 single-zone price?
Permit, materials, equipment, standard line-set run, pad/stand, electrical disconnect, commissioning, and inspection support. Unusual runs or panel upgrades are scoped up-front.
What warranty do you offer on multi-zone systems?
10-year parts and labor when installed and commissioned by our team and registered per the manufacturer’s terms.
ADU HVAC done right: sizing, permits, and electrical
Most ADU comfort problems trace to three shortcuts: sizing by guesswork instead of a real load calculation (a 400 sq ft studio and a 1,200 sq ft two-bedroom are completely different projects), skipping permits (which surfaces during sale or refinance), and ignoring electrical capacity — many ADUs share a panel already near its limit. We handle all three properly: Manual J sizing per unit, permit and inspection coordination, and panel evaluation upfront. Single-zone mini-splits suit most studios; multi-zone systems fit larger units with separated bedrooms. Converting the garage too? See our gas-to-electric guide — ADU projects are a natural moment to plan panel capacity for everything at once.
