New Construction HVAC in Louisville, KY

What new construction HVAC generally covers

• Room-by-room heating and cooling load calculations from the plans
• Duct design and layout, with return air sized for each area
• Equipment selection matched to the calculated load and the design conditions
• Zoning strategy for multi-level and multi-wing layouts
• Rough-in coordination with framing, plumbing, and electrical trades
• Ventilation and combustion air per applicable code
• Refrigerant lineset, condensate, and electrical routing
• Commissioning, airflow balancing, and documented startup readings
• Coordination with builders, inspectors, and the permit process

Design comes before equipment

The temptation on a new build is to pick equipment early because it is a line item that needs a number. Doing it in that order tends to lock in a size before anyone knows what the building needs, and the ductwork then gets fit around the equipment instead of the load.

Running the calculations first usually produces smaller, better-matched equipment than a square-footage estimate would, especially in newer, tighter homes. That matters for humidity control as much as capacity, because equipment sized to a real load runs longer cycles and dehumidifies properly.

Coordination is most of the job

On an active site, HVAC competes for the same joist bays and chases as plumbing and electrical. The trades that get there first win, and ducts are the least forgiving of the three when it comes to being rerouted.

• Locating chases and drops with the framer before rough-in
• Protecting duct runs from being crushed or cut by other trades
• Confirming equipment platforms, clearances, and service access early
• Planning flue and vent terminations with roofing and siding
• Placing outdoor units where grading, drip lines, and finished patios allow
• Sequencing rough-in and trim-out around insulation and drywall

Commissioning is the part that gets skipped

A new system should leave with measured proof that it works: airflow at the equipment and at the registers, static pressure within the range the blower is rated for, refrigerant charge verified by measurement, and each stage and zone confirmed to operate.

That documentation is also what makes future service straightforward, because someone can compare readings later and see what has drifted. On tenant build-outs it doubles as a record for the landlord and the next occupant.

Common questions

Do you work with builders and general contractors?

Yes. Custom homes and tenant fit-outs both involve coordinating with a builder or GC, other trades, and the inspection process as a normal part of the work.

What is a load calculation, and why does it matter on a new build?

It is a room-by-room analysis of how much heating and cooling a building needs based on its envelope, windows, orientation, and air tightness. On new construction it determines both equipment size and duct design, so it drives nearly every other decision.

When should HVAC get involved in the project?

As early as the plans are firm. Duct routing, chases, equipment locations, and vent terminations are much cheaper to place on paper than to solve after framing.

Can you design zoning for a multi-level home?

Yes, and it is worth planning rather than adding later. Upper floors, walk-out lower levels, and wings with heavy glass behave very differently, and the zoning strategy affects both duct design and equipment selection.

Do you handle tenant build-outs in existing buildings?

Yes. Build-outs bring their own constraints, since existing equipment, ductwork, and roof penetrations have to be worked with, and the space often needs re-zoning to match the new layout.
