we're at the table — before equipment, ductwork, or Title 24 become a problem
Get the HVAC right the first time, before drywall goes up.
Most HVAC headaches in new builds trace back to one of three things: equipment sized by rule-of-thumb instead of Manual J, ductwork designed as an afterthought once framing is done, and Title 24 compliance handled in a panic right before close-out. We do it the other way around — load calcs first, duct layout coordinated with the framing plan, compliance documented as we go.
We work with GCs, custom-home builders, developers, and architects across the full range — new SFRs, ADUs, and multi-family on the residential side; office buildings, restaurants, retail, medical, light industrial, and full tenant improvements on the commercial side. Single units or full subdivisions, single suites or whole buildings — same C-20 contractor, same documentation standards.
What you actually get when you call us.
Manual J/D/S on every project.
Real load calculations, real duct design, equipment selected to match — not the size we happened to have on the truck. Works for a single ADU or a multi-zone office floor. Documented in the permit set so the inspector sees it on day one.
Title 24 done right.
Residential or nonresidential — HERS testing, refrigerant charge verification, duct leakage testing, mechanical acceptance testing, and full CF-2R/CF-3R or NRCC/NRCA documentation. We coordinate with your Title 24 consultant or run the energy compliance ourselves.
Residential to mid-size commercial.
Custom homes, ADUs, and multi-family — plus office buildings, restaurants, retail centers, medical suites, and tenant improvements. One C-20 contractor, one project manager, sequenced around your GC and the other trades.
Four steps. No surprises.
Design & load calcs
Plans review, Manual J load calc, equipment selection, duct design, Title 24 strategy. Delivered as a permit-ready spec packet your design team can drop straight into the set.
Rough-in
Refrigerant lines, condensate, ductwork, line-voltage, and equipment platforms — sequenced with framing, plumbing, and electrical so nothing has to be reopened.
Set & trim
Equipment set, registers, thermostats, controls. Coordinated with drywall, paint, and finish trades so nothing gets damaged or holds up the schedule.
Test, commission & document
HERS verification, charge & airflow testing, system commissioning, owner walkthrough, and the full CF documentation packet for closeout and CO.
New Construction HVAC — Design, Install & Title 24: questions homeowners ask us most.
The honest, in-plain-English answers we’d give a neighbor calling on the phone.
Do you work directly with general contractors and architects?
Yes — that’s the bulk of our new-construction work. We provide Manual J/D/S load calculations, equipment specs, duct layouts, and Title 24 documentation as part of the design phase. We coordinate rough-in and final with the GC on the schedule that works for the build.
What kind of projects do you take on?
Custom homes, ADUs, room additions, gut remodels, and tenant improvements across the San Gabriel Valley. We handle ducted central systems, multi-zone ductless, hybrid layouts, and full Manual J/D/S design-build packages.
Can you provide a HERS rater for Title 24 compliance?
We coordinate with established HERS raters we’ve worked with for years, and we deliver our installs to pass HERS verification on the first visit — duct leakage, fan watt draw, refrigerant charge, airflow. We don’t do the rating ourselves (that’d be a conflict of interest), but we handle every piece of the work that gets graded.
