The tune-up upsell: worth it once a year, not as a sales visit
Maintenance is real: the Department of Energy says neglecting it ensures a steady decline in performance while energy use steadily rises. The catch is that a $175 to $350 tune-up is also the cheapest way for a sales-driven company to get a technician in front of your equipment.
What is probably happening
- A legitimate tune-up checks the refrigerant charge, tests for leaks, checks electrical connections and the thermostat, cleans the coils and condensate drain, and on a furnace inspects the burners and heat exchanger and tests for CO.
- A maintenance plan at $150 to $300 a year for the whole system can be fair if it includes both seasons and a priority call in a heat wave.
- The upsell version: a $49 special that ends with a list of urgent parts, a 'cracked heat exchanger', or a replacement quote.
Do this in the next five minutes
- Ask for the checklist in writing before you book. The Department of Energy's list is a good benchmark.
- Ask what readings you will get on paper: temperature split, refrigerant pressures, capacitor values, CO at the registers.
- Do the free parts yourself: change the filter every month or two in cooling season, keep 2 feet clear around the outdoor unit, and run a stiff wire through the drain channels.
- If the tune-up ends with an urgent replacement, use the scare tactic path on this site before you sign anything.
Do not
- Do not buy a plan that only includes one visit a year but is priced for two.
- Do not accept 'needs a recharge' at a tune-up with no leak found.
- Do not sign for parts on the spot without the reading that failed. A capacitor that tests within its rating does not need replacing.
Who to call
A licensed HVAC technician
Refrigerant checks need a Section 608 certified technician, and a furnace combustion check needs a combustion analyzer. A handyman cannot do either.

Ask this contractor, on the phone, before anyone comes out
Tap each one as you ask it.
- What exactly is on the tune-up checklist, and will I get the readings in writing?
- Does the plan cover both the cooling and heating visit, and is there a priority response in peak season?
- Does the plan discount repairs, and by how much?
- Is the technician paid commission on parts or replacements sold at the visit?
End the call if
- A tune-up that ends in a replacement quote with no readings.
- A cracked heat exchanger found at a tune-up with nothing shown to you. The California CSLB documented that exact upsell.
- A very low advertised tune-up price paired with pressure to buy parts today.
