Heating & Cooling

New Construction HVAC Installation

Freedom Heating installs heating, cooling, ventilation, and ductwork systems for new homes, ADUs, multifamily buildings, and commercial construction projects throughout the Central Coast.

We review the approved mechanical plans, install the HVAC systems those plans specify, and perform applicable startup and operational testing.

A new construction HVAC installation is a sequence rather than a single appointment. Equipment, ductwork, ventilation, and controls are laid out before framing, installed as the building goes up, and started up once the project is ready. Contacting the HVAC contractor early is what keeps that work from being compressed into the last weeks of a project.

Freedom Heating reviews architectural and mechanical plans before installation and works from the HVAC plans prepared by outside mechanical engineers. We do not prepare that engineering. Reviewing drawings early lets equipment locations, duct routes, and clearances be confirmed while there is still time to change them.

Projects include custom and spec homes, ADUs, additions and major remodels, apartments and condominiums, mixed-use buildings, new commercial buildings, offices, retail space, and tenant improvements. Underground ductwork, rough-in, equipment setting, and finish work are scheduled around the phases a project actually has.

Ductwork for our installations is fabricated in our own shop, and equipment is specified to the approved plans. Startup, operational testing, airflow adjustments, and installation-related punch-list work close out the job. Where independent verification is required, we coordinate with the HERS rater or third-party provider rather than performing that certification. Freedom Heating is the HVAC contractor on these projects, not the general contractor.

Important HVAC Planning Considerations

HVAC plans are not yet available for installation review
Equipment locations have not been confirmed before related construction work
Duct routes may conflict with framing or other building elements
Underground ductwork has not been identified before those areas are covered
Supply register and return-air locations do not match the approved plans
Ventilation and exhaust ductwork is missing where the plans specify it
Equipment and controls do not match the approved project requirements
The HVAC contractor was contacted late in the construction process

Common New Construction Questions

These questions come up in nearly every project conversation. Short answers are here; the longer discussion follows in the sections below.

When should I contact an HVAC contractor for a new home?

Before construction begins, while the plans are available to review. Early contact gives time to confirm equipment and duct routes and to request an estimate before the framing schedule is set.

Do I need approved mechanical plans before installation?

Yes. Freedom Heating installs to mechanical plans prepared by outside mechanical engineers. We review architectural and mechanical drawings, but we do not prepare or certify that engineering design.

Can HVAC ductwork be installed underground?

Where the approved plans specify it, typically in slab-on-grade construction. Underground ductwork has to be identified and installed before those areas are covered by the building.

What happens during HVAC rough-in?

Rough-in happens during framing: duct routes, equipment locations, supply and return openings, and ventilation runs are installed and checked against the plans before walls and ceilings close.

Can a new construction project use a heat pump?

Often, when the approved plans call for one and the equipment suits the project. A heat pump provides heating and cooling from one system, and it can serve a whole building or part of a mixed design.

Can ductless mini-splits be installed in new homes or ADUs?

Yes. Ductless systems are installed where the plans specify them, commonly for ADUs, additions, and spaces that ductwork cannot reach well.

Who handles HERS testing and verification?

Independent HERS raters or certified third-party verification providers. Freedom Heating coordinates with them; our own startup and operational checks are separate from their verification.

What happens during HVAC startup?

Manufacturer-recommended startup procedures, heating and cooling operating checks, control testing, applicable airflow and refrigerant checks, airflow adjustments, and a walkthrough of basic system operation.

Planning HVAC Installation Before Construction

Plan review is where an installation starts. Before work is scheduled, we read the architectural drawings alongside the mechanical plans, because the HVAC layout has to agree with the building that is actually framed: floor levels, mechanical closets, attic and crawlspace access, and the paths ducts will take.

The mechanical plans are prepared by outside mechanical engineers. Freedom Heating works from them, reviewing for installation, confirming the equipment and ductwork they specify, and raising conflicts early rather than after framing. We do not prepare or certify that engineering design.

What early review covers

  • Architectural and mechanical drawing review
  • Equipment locations and service access
  • Duct routes and clearances
  • Underground ductwork requirements
  • Register, return, and thermostat locations
  • Ventilation and exhaust runs within scope

Estimates are best requested before construction begins, while plan changes are still inexpensive. The estimate reflects the approved plans and the contracted scope.

Heating and Cooling Equipment for New Construction

Equipment follows the approved plans. Working from those requirements, we supply and install Bryant equipment, and other major brands when appropriate, and we confirm compatibility and availability before accepting an installation.

Gas furnaces

Forced-air heating where the plans specify it, including the venting, gas piping, and clearances the installation requires.

Air conditioners and heat pumps

Split and packaged cooling systems, with heat pumps providing both heating and cooling where the design calls for them.

Air handlers, mini-splits, and rooftop units

Air handlers, ductless mini-splits for ADUs and specific spaces, and commercial rooftop or packaged equipment for larger projects.

Availability and compatibility

Equipment must suit the plans and the project. Not every type fits every project, and availability is confirmed before an installation is accepted.

We install the equipment specified in the approved mechanical plans. Equipment and installation warranty terms vary by manufacturer and by project.

Ductwork, Rough-In, and Custom Sheet Metal

Ductwork is the part of a new construction HVAC job that is hardest to change later. Routes, sizes, and openings are set while the building is open, and finish components follow weeks later.

Underground ductwork

Where the plans specify it, often in slab-on-grade construction, ductwork goes in before those areas are covered.

Framing-stage rough-in

Duct runs, equipment locations, supply and return openings, and ventilation paths are installed and checked against the plans.

Flexible, insulated, and custom ductwork

Flexible and insulated duct where appropriate, plus custom sheet metal fabricated in our shop for our own HVAC installations.

Finish components and ventilation

Supply registers and return grilles, exhaust and fresh-air ductwork within the contracted scope, and the trim-stage items that complete the system.

Sheet metal is fabricated for Freedom Heating's own installations. We do not provide standalone fabrication, retail sheet-metal sales, or fabrication for unrelated contractors.

Installation Phases and Construction Timing

A typical project moves through the stages below. The order depends on the building, the approved plans, and when the project is ready for each phase.

This is an illustrative sequence, not a construction schedule. Freedom Heating does not manage the overall project schedule, and we do not promise start dates or fixed lead times.

  • Plan review and estimate request
  • Applicable underground ductwork
  • HVAC rough-in during framing
  • Equipment and duct installation
  • Registers, grilles, thermostats, and finish components
  • Startup and operational checks
  • Final adjustments and coordination with independent verification

Phases may be combined, repeated, or omitted depending on the project and the contracted scope.

Mechanical Permits and Independent HERS Verification

Installation follows the approved mechanical plans and the agreed contract. Permits and verification sit outside that installation scope, and it helps to know who holds which responsibility before a project starts.

Who obtains the permit

Mechanical permits are obtained by the general contractor or the property owner. Freedom Heating works under those permits.

Inspections

The permit holder works with the building department. We do not obtain permits or schedule building department inspections.

Independent verification

Where HERS or third-party verification applies, we coordinate with the independent rater or provider. That verification is separate from our own startup checks.

What we do not certify

We do not perform HERS certification, duct leakage verification, refrigerant charge verification, or energy compliance certification.

Installation work is performed to the approved plans and contracted scope; it is not a certification of code compliance or inspection outcome.

Startup, Airflow Adjustments, and Final Operation

Startup is where the installed system is confirmed to operate. Procedures follow the equipment manufacturer's requirements and the contracted scope, so not every check applies to every project.

Startup and operating checks

Manufacturer-recommended startup, heating operation and heating cycles, cooling operation for air conditioning and heat pumps, and thermostat and control testing.

Airflow and balancing

Supply and return airflow measurements when appropriate, with register and damper adjustments to balance delivery between rooms or zones.

Refrigerant, gas, and electrical

Refrigerant pressure, temperature, and charge checks per manufacturer requirements, gas pressure and furnace checks where applicable, electrical readings, and safety-control verification.

Condensate, ventilation, and zoning

Condensate drainage and pump checks, ventilation and exhaust operation, and zoning or multi-zone control testing.

At handoff

  • Required startup readings or manufacturer checklists
  • Final adjustments and installation-related punch-list items
  • A walkthrough of thermostat operation and basic system use

Procedures depend on the equipment and contract requirements. Equipment startup is not the same as independent HERS verification.

New Construction HVAC Around Watsonville and the Central Coast

Our shop is in Watsonville, and new construction work takes us across Santa Cruz, Monterey, and San Benito counties — Freedom, Aptos, La Selva Beach, Corralitos, Soquel, Capitola, Santa Cruz, Scotts Valley, Salinas, Monterey, and Hollister.

Much of the residential work is custom homes, ADUs, additions, and major remodels, where the HVAC layout has to fit a tight mechanical space. Multifamily and mixed-use projects bring per-unit equipment and longer duct runs, and commercial work brings rooftop units, tenant improvements, and build-outs.

Coastal projects deal with humid air and salt exposure, while inland sites swing harder between heating and cooling. Those conditions show up in equipment selection and in how thoroughly ductwork is sealed and insulated. Wherever the project sits, we install from the approved mechanical plans, and requests for estimates are best made before construction begins.
