Getting an accurate AC or furnace replacement quote in the Dallas-Fort Worth area shouldn’t require a phone call or a sales visit. That’s why Expedition Heating & Air built this free online HVAC replacement cost calculator — so homeowners in Garland, Plano, Richardson, Mesquite, Rowlett, Sachse, and across DFW can get real pricing in under two minutes, any time of day.
Our calculator gives you a Good/Better/Best range based on your home’s square footage, your current system size, and the type of equipment you need — whether that’s a full AC and air handler replacement, a gas furnace swap, or a heat pump system. Every estimate reflects what we actually charge, not a bait-and-switch number designed to get us in your door.
What affects the cost of HVAC replacement in North Texas?
System size (tonnage) is the biggest factor — a 2-ton system for a smaller home costs significantly less than a 5-ton system for a larger one. Efficiency rating matters too: a standard 14–15 SEER unit will cost less upfront, while a high-efficiency 18 SEER system saves more on your monthly Oncor or CoServ electric bill over time. Installation location (attic vs. closet vs. garage) and any add-ons like UV light systems, whole-home dehumidifiers, or air purifiers will also affect your final price.
