Single-stage, two-stage and modulating
- Single-stage (lowest price): runs at full power whenever on.
- Two-stage: runs on low most of the time, for steadier temperatures and quieter operation.
- Modulating (highest price): adjusts output in small steps for the best comfort and efficiency.
How to get a fair quote
- Get at least three written quotes that list the brand, model number, size (tons or BTU) and efficiency rating.
- Ask whether the price includes permits, removal of the old unit, refrigerant, a new thermostat and any duct or electrical work.
- Ask for a load calculation (Manual J) instead of matching the old unit's size by default.
- Compare labor warranties (1 to 10 years) as well as the manufacturer's parts warranty, and register the equipment.
- Schedule non-urgent work in spring or fall, when contractors are less busy and more willing to discount.
