What makes up the price
Cost by size
National averages, before any local adjustment. Computed from the same model as the calculator above, so the two always agree.
| How many systems | Systems | Typical | Range |
|---|---|---|---|
| 1 systems | 1 | $185 | $150 to $225 |
| 2 systems | 2 | $285 | $235 to $355 |
Ask for the numbers
The only way to tell a real tune-up from a filter change and a hose-down is to ask what was measured. A proper visit produces readings, and a technician who has taken them will hand them over without hesitation.
On the cooling side:
- Temperature split — the difference between return and supply air, which should be about 16 to 22°F. Outside that range something is wrong with airflow or charge.
- Refrigerant pressures with superheat and subcooling, which is how charge is actually judged. "It's a little low, I topped it off" without those numbers is a guess, and a system that needs refrigerant has a leak.
- Static pressure across the air handler, which is the single most useful measurement in the trade and the one most rarely taken. High static means restricted airflow — a dirty coil, a crushed duct, an undersized return — and it shortens equipment life.
- Capacitor microfarads and compressor amp draw, which is how a failure is predicted rather than reacted to.
On the heating side:
- Combustion analysis — CO in the flue gas, and the gas pressure at the manifold.
- Heat exchanger inspection, visually and ideally with a camera.
- Draft, and carbon monoxide in the living space.
- Flame pattern and ignition timing.
That heating list is safety rather than efficiency, which is the real argument for a furnace visit and the reason not to skip it in a house with a gas appliance.
What it costs
| One-off | On an annual plan | |
|---|---|---|
| Cooling only | $155 | $120 |
| Heating only | $175 | $135 |
| Both | $185 | $140 |
| Two systems, both | $285 | $225 |
An annual plan is normally two visits — one before cooling season, one before heating — so a typical plan comes to around $280 a year for one system.
Note what is not in this calculator: floor area. A tune-up is the same work on a 1,200 square foot house as on a 3,000 square foot one — the same coil, the same burners, the same measurements. What scales is the number of systems. A company quoting maintenance by the square foot is quoting something else.
Is a maintenance plan worth it?
The per-visit discount is about 22%, and it is genuine for two reasons worth separating:
- Routed work is cheaper to deliver than a dispatched call. The company fills quiet weeks in spring and fall with scheduled visits.
- They are buying first refusal on your repairs. A maintenance customer is who you call when something fails, and that is worth more to them than the discount costs.
Neither is generosity, and that is fine — it is a fair trade. But it means the discount on the visits is not where the value is. The two things that make a plan worth having are:
- A repair discount, usually 10 to 20%. On one capacitor it is trivial; on a compressor it is not.
- Priority scheduling. In the first heat wave of the year, a maintenance customer is seen the same day and everybody else waits a week. In August, in Texas, that is the whole value of the plan.
What to check before signing: whether it auto-renews, whether the price is held for more than a year, whether the visits roll over if you miss one, and whether it is transferable if you sell the house.
What it actually saves
Honest arithmetic, because the industry's claim of "up to 30%" is not a figure anyone should repeat.
- A dirty coil or restricted airflow genuinely costs efficiency, and cleaning it back is a real gain — but the gain is recovering what was lost, which means a well-maintained system never shows it in the first place.
- The documented saving from annual maintenance on a system that is already clean is small. The case for maintenance is mostly about failure avoidance and lifespan, not about the monthly bill.
- The real money is in what gets caught: a weak capacitor replaced in April for $150 instead of a seized compressor in July, a condensate drain cleared before it overflows into a ceiling, a cracked heat exchanger found before it matters.
So the honest summary: a tune-up is cheap insurance with a modest efficiency component, and the furnace half has a safety component that is not optional. It is not an energy-saving product.
What you can do yourself, and what you cannot
Yourself, and it matters more than the visit:
- Change the filter on schedule — monthly for a 1-inch filter in a dusty house, quarterly for a 4-inch media filter. A blocked filter is the commonest cause of everything that goes wrong.
- Keep the outdoor unit clear. Two feet of space all round, nothing growing against it, and no grass clippings blown into the coil. Hose the coil from the inside out with the power off, gently.
- Pour a cup of vinegar down the condensate drain at the start of cooling season.
- Keep supply and return registers unblocked — a closed-off room does not save money, it raises static pressure.
Not yourself: anything involving refrigerant, which requires certification to handle legally; combustion testing, which requires an analyzer; and static pressure, which requires a manometer and knowing where to drill.
When to call for a repair instead
A tune-up is scheduled maintenance. Call for a diagnostic visit instead if:
- The system is short-cycling or will not start.
- There is ice on the refrigerant lines or the indoor coil.
- A burning or musty smell when it starts, or a smell of gas at any time, which is an emergency rather than an appointment.
- Water around the air handler, which is a blocked condensate drain and will reach a ceiling.
- The breaker trips when it starts.
- Rooms have become uneven when they were not before.
Booking a $185 tune-up for a system that is already failing wastes the visit — the technician will diagnose it, charge for the diagnosis and tell you what it needs.
What you are paying for
One system, heating and cooling, as a one-off visit, at $185:
| Labor, about 1.3 hours | around $77 |
| Coil cleaner, pan tablets and small parts | $18 |
| The visit | $40 |
| Overhead and margin | the balance |
The filter is not in that figure, because most tune-ups fit the filter the householder already buys. A capacitor or a contactor is a repair rather than maintenance, and should be quoted when it is found rather than appearing on the invoice.
Questions worth asking
- What will you measure, and will I get the readings?
- Is static pressure part of it?
- Do you do a combustion analysis on the furnace?
- Is the filter included or should I have one ready?
- How long will the visit take? Under half an hour for both systems is not a tune-up.
- If you find something, will you quote it before doing it?
- What is the repair discount on the plan, and the priority commitment?
- Does the plan auto-renew, and is the price held?
- Do unused visits roll over?
- Is the plan transferable if I sell?
Common questions
How much does an HVAC tune-up cost?
About $185 for a visit covering both heating and cooling as a one-off, or $140 on an annual plan — so roughly $280 a year for the usual two visits. A single-season visit is $155 for cooling or $175 for heating, and two systems come to $285 one-off or $225 on a plan. Floor area does not come into it: a tune-up is the same work on a small house as a large one.
What should be included in an HVAC tune-up?
Measurements, and you should ask for them. On cooling: temperature split across the air handler, which should be 16 to 22°F; refrigerant pressures with superheat and subcooling; static pressure, which is the most useful reading in the trade and the most rarely taken; and capacitor microfarads and compressor amp draw. On heating: combustion analysis with CO, manifold gas pressure, a heat exchanger inspection, draft, and a carbon monoxide check in the living space. A visit that produces no numbers is not a tune-up.
Is an HVAC maintenance plan worth it?
Usually, but not for the reason it is sold. The 22% discount per visit is genuine — routed work is cheaper to deliver, and the company is buying first refusal on your repairs — yet the value is in the two things attached to it: a 10 to 20% repair discount, which matters on a compressor rather than a capacitor, and priority scheduling in the first heat wave, when everybody else waits a week. Check whether it auto-renews, whether the price is held, whether missed visits roll over, and whether it transfers if you sell.
How much does an HVAC tune-up save on energy bills?
Less than the industry implies. A dirty coil or restricted airflow genuinely costs efficiency and cleaning it back is a real gain, but that is recovering a loss rather than creating a saving — a system kept clean never shows it. The documented saving from annual maintenance on an already-clean system is small. The actual case for a tune-up is failure avoidance and lifespan, plus the safety side on a gas furnace, and it is better understood as cheap insurance than as an energy product.
How often should HVAC be serviced?
Twice a year is the standard recommendation — cooling in spring, heating in fall — and that is what an annual plan buys. Once a year is defensible on a cooling-dominated system in a mild climate, and the furnace visit is the one not to skip in a house with a gas appliance, because the combustion and carbon monoxide checks are safety rather than efficiency. Each system wants checking shortly before the season it is about to work through.
What is temperature split and why does it matter?
The difference between the air going into the return and the air coming out of a supply register, which on a working cooling system should be about 16 to 22°F. Too small means low refrigerant charge or poor heat transfer; too large usually means restricted airflow. It takes two thermometers and a minute, it is the quickest honest check of whether a system is performing, and any technician should be able to tell you what yours was.
What is static pressure and should it be measured?
The resistance the blower is working against, measured with a manometer across the air handler, and it is the single most useful measurement in the trade as well as the most rarely taken. High static pressure means restricted airflow — a dirty coil, a crushed or undersized duct, a blocked return — which costs capacity, raises bills and shortens the blower and compressor life. Ask whether it is part of the visit; the answer tells you a great deal about the company.
Should a tune-up include adding refrigerant?
No. A sealed system does not consume refrigerant, so a system that is low has a leak, and topping it up without finding the leak is selling you the same gas every year. If a technician says the charge is low, ask for the superheat and subcooling readings that justify it and for a leak search to be quoted. Routine "top-ups" on an annual visit are a warning sign rather than a service.
What can I do myself between visits?
The filter, on schedule — monthly for a 1-inch filter in a dusty house, quarterly for a 4-inch media filter — which prevents more problems than anything a technician does. Keep two feet clear all round the outdoor unit and nothing growing against it, and hose the coil gently from the inside out with the power off. Pour a cup of vinegar down the condensate drain each spring. And leave registers open: closing off a room raises static pressure rather than saving money.
When should I call for a repair instead of a tune-up?
When the system is short-cycling or will not start, when there is ice on the refrigerant lines or the indoor coil, when water is pooling around the air handler, when the breaker trips on startup, or when rooms have become uneven. A smell of gas is an emergency rather than an appointment. Booking maintenance for a system that is already failing wastes the visit — the technician will diagnose it, charge for the diagnosis and tell you what it needs.
How long should an HVAC tune-up take?
About an hour and a quarter per system for a visit covering both heating and cooling, and 45 minutes to an hour for a single season. Under half an hour for both systems is not a tune-up — it is a filter change and a visual look, which is a legitimate product but not this one. If a visit is quoted at a notably low price, the honest question is how long it is scheduled for.
Does a tune-up cover two systems in one visit?
Each system is charged separately because each has its own coil, burners and set of measurements, but doing both on one visit is cheaper than two visits — $285 against $370 for two one-off single-system visits, because the drive-in and the paperwork happen once. If a house has two systems, book them together.
