What Should I Expect During a Residential HVAC Installation?

A: It starts before installation day, with a measurement rather than a guess.

Before. We do a load calculation on your actual house — square footage, insulation, window exposure, duct condition — and give you a written estimate. That estimate is free on a new or replacement system, with no $95 diagnostic fee attached. If you're financing, Wisetack rate checks don't affect your credit.

Installation day. Old equipment comes out and is hauled off. New indoor and outdoor units get set, line sets and drains run, ducts connected or corrected, electrical and the thermostat wired in. Newer ducted systems use R-454B, an A2L refrigerant, which carries its own handling requirements — that's a licensed-technician job, and Trinity holds Oklahoma mechanical licence OK Mech 120057.

Before we leave. The system is charged, airflow checked, and run through both modes. You get shown the filter location and size — worth knowing, since red dirt loads filters here faster than most climates — and how to run the thermostat.
