ACCA Manual J load calculation, Manual S equipment selection, Manual D duct design. We size HVAC to the actual heat loss of your home, then commission with real measurements so the comfort matches the spec.

What We Offer

Whole-home system design

Manual J load calculation and Manual S equipment sizing. No rule-of-thumb guesses that leave one bedroom freezing and another roasting.

Duct design and install

Manual D duct layout with proper static pressure and airflow targets. Sealed, insulated, and sized for the rooms that actually need the air.

Furnace, AC, and heat-pump install

Gas and electric furnaces, central AC, and cold-climate heat pumps. Paired equipment matched to the blower and duct system.

New-construction coordination

We show up on your GC's schedule for rough-in, come back for trim-out after drywall, and handle our own permits and inspections.

Commissioning and documentation

Static pressure, airflow, refrigerant charge, and combustion measurements documented. So you know the system is right, not just installed.

Why It Matters Here

Right-sized, not just replaced

Too many new-construction HVAC systems are sized off a square-foot rule of thumb that leaves one bedroom freezing in January and another roasting in July. We run an ACCA Manual J load calculation, size the equipment to the actual heat loss of the house, and commission the system with static pressure and airflow measurements so the comfort matches the spec.

HVAC Questions

Frequently Asked Questions

Common questions about new installations in the Twin Cities metro. Don't see yours? Call us at 763-301-4829.

Yes, every time. Manual J load calculation for the whole home, Manual D for the ductwork, Manual S for equipment selection. This is how you end up with a furnace that is not oversized (which short-cycles, runs humidity up in summer, and wastes fuel) and an AC that actually dehumidifies.
Yes. We coordinate with the general contractor, handle the permits and inspections, and install during rough-in with trim-out after drywall and paint. We work across the Twin Cities metro on residential and light commercial.
For most Minnesota homes today, a cold-climate heat pump paired with a gas or electric backup is the most flexible answer. It gives you efficient cooling, efficient heating down to roughly 0°, and a backup for the coldest stretches. We walk through the operating cost math for your specific home and utility rates.
