Heating and Cooling Consulting for Construction and Renovation

Equipment selection from a load, not a rule of thumb

Sizing by square footage or by what was there before is how buildings end up with furnaces that short-cycle and air conditioners that cool without dehumidifying. We base recommendations on a heating and cooling load that accounts for insulation, windows, orientation and occupancy, and we flag where the design team should confirm assumptions.

From there we compare furnace, boiler, heat pump and air conditioning options. As a Navien-certified contractor we can include Navien furnaces, boilers and heat pumps in that comparison alongside other equipment, based on what suits the building.

Ductwork and renovation planning

On a renovation the ductwork is usually the constraint. New equipment connected to old, undersized trunks and returns will be noisy and uneven. We assess what can be reused, what needs to be enlarged or rerouted, and where soffits or chases will be needed, so the architect can plan for them.

Where ducts are not practical — additions, finished attics, older masonry buildings — we look at ductless or hydronic alternatives.

Efficiency upgrades

Higher-efficiency furnaces, modulating boilers, heat pumps and better controls may reduce energy use. Actual savings vary with the building, the occupants and utility rates, so we explain what each option changes rather than promising a number.

Commissioning and startup support

A correct installation can still run poorly if it is never set up. At startup we check gas pressure and combustion on fuel-burning equipment, static pressure and airflow, refrigerant charge, condensate drainage and controls sequencing, and we record the readings for the owner.
