How Do I Choose the Right HVAC System for My Home?

A: Start with a load calculation on your specific house — square footage, insulation, window exposure, and duct condition — not a rule of thumb off the old unit's nameplate. Oversized equipment short-cycles; undersized equipment never catches up in an Oklahoma August.

The second question is what your property actually has to work with. Rural McClain, Grady, and Garvin County homes are frequently on propane rather than city gas, which changes furnace orifices. Homes on acreage are candidates for geothermal, which is one of the two things Trinity specializes in alongside custom duct design. In-town homes in Norman, Moore, or Edmond usually come down to a straight AC-and-furnace pair or a heat pump; a room or addition with no ductwork often points to a mini-split.

We install ClimateMaster geothermal, Samsung, and American Standard. Whatever the size, new equipment has to meet Oklahoma's DOE South-region minimum of 14.3 SEER2, and heat pumps 7.5 HSPF2.

Estimates on a new system are free — no $95 diagnostic fee. Call 405-420-4895.
