When to get an HVAC inspection
- Buying a home: general home inspectors only do a basic check; an HVAC pro can estimate remaining life and spot costly problems.
- Before a big repair: a second opinion on a compressor, coil or heat exchanger diagnosis.
- High bills or uneven comfort: a duct leakage test finds wasted air.
Inspection vs. tune-up
An inspection tells you the condition of the system; a tune-up also cleans and adjusts it. For yearly upkeep, a tune-up or maintenance plan is the better value.
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.
