What a tune-up includes
- Replace or clean the air filter
- Clean the outdoor condenser coil and clear debris
- Inspect and clean the indoor evaporator coil (when accessible)
- Clear the condensate drain line and check the pan
- Test the capacitor, contactor and electrical connections
- Measure refrigerant pressures and temperature split
- Lubricate motors and check the blower
- Test thermostat operation and safety controls
Avoiding cheap tune-up upsells
Very low-priced tune-ups are sometimes used to sell repairs. Ask for readings (refrigerant pressures, capacitor microfarads, temperature split) and photos of any problem before agreeing to extra work, and get a second opinion on big-ticket items like a compressor or coil.
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.
