AC installation cost by system.
Installed pricing for Marshall, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Marshall, Texas, AC installation costs typically range from $3,100 to over $10,000 depending on system type and complexity. With a median home age of 57 years, many homes need new ductwork or system upgrades. The hot-humid climate makes cooling a priority, and a heat pump is often a strong fit due to its efficiency and eligibility for the federal 25C tax credit (30% up to $2,000). All work must be done by a TDLR-licensed contractor who pulls the required mechanical permit. Prices vary by system choice: central AC like-for-like runs $3,100–$6,200, while a new central AC with ductwork can cost $4,600–$10,100+. Ductless mini-splits are $2,300–$6,200, and heat pumps $3,900–$9,300+. The SEER2 minimum is 14.3 for the Southeast region, and newer refrigerants like R-454B or R-32 are becoming standard.

Recommended unit for Marshall
Given Texas’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Marshall homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

What Affects AC Installation Cost in Marshall
The main cost drivers are system type, ductwork condition, and home size. Older homes (median built 1969) often require new or modified ducts, adding $1,500–$4,000+. A heat pump costs more upfront than a standard AC but qualifies for the 25C tax credit. Labor rates reflect the local market, and permit fees (required by Texas law) are included in the quote. High-efficiency units (above 14.3 SEER2) may cost more but offer long-term savings.
