Key takeaways
- Size, efficiency and equipment type set most of the price
- Duct work and electrical changes can add a lot
- Two-stage and variable-speed models cost more up front
- A good quote lists equipment, labor and extras in writing
What sets the price
The biggest factors are the size of the system, its efficiency rating and its type: a basic air conditioner and furnace, a heat pump, a dual fuel system or a ductless setup. After that come the ducts, the electrical work, the thermostat, permits and any needed changes to the pad, the vent or the gas line.
Two houses of the same size can price differently because of the ducts and the equipment chosen. A quote should tell you why.
What a good quote includes
Look for the equipment make and model, capacity, efficiency rating, what is included in labor and what is not, warranty terms and the schedule. Ask whether a load calculation was done and whether the ducts were checked.
Ask about haul-away, permits, the thermostat and any duct changes. If something is vague, ask for it in writing.
Planning your budget
Use our Tonnage Finder to see the size range for your house, then ask for a written quote based on a visit. It helps to decide whether you prefer lower up-front cost or lower operating cost.
If budget is tight, ask about a good-better-best comparison and what each step actually changes.

Quick answers
Is the cheapest quote the best deal?
Not necessarily. Differences in sizing, duct work and installation quality can matter more than the equipment price.
Does a higher efficiency rating always pay off?
It depends on how much you use the system and how long you stay. We can compare operating costs for your house.
