What Does a Home HVAC Installation Include?

A: A complete changeout covers the removal of the old equipment, the new indoor and outdoor units, the line set and electrical connections, a look at the ductwork the system has to breathe through, and a full startup test before we leave.

The duct step is the one homeowners skip and later regret. Custom duct design is one of Trinity's two specialties, and in this region red-dirt dust loads ducts, blower wheels, and filters faster than most climates. If sealing is warranted it runs $800-$2,500, and cleaning runs $400-$800; either is quoted separately and never buried in the install number.

What the price covers: a typical residential installation lands between $7,500 and $10,000, averaging about $8,000, with equipment meeting Oklahoma's 14.3 SEER2 minimum. Estimates for a new or replacement system are free — the $95 diagnostic applies to repair calls, not replacement quotes.

If spreading the cost helps, Wisetack financing has no prepayment penalties and checking a rate does not affect your credit. Start at installation or call 405-420-4895.
