HVAC maintenance costs $300 a year on average in 2026, with most homeowners paying between $150 and $500 depending on how many visits are included and how many systems run on the property. That average covers two seasonal tune-ups — one for the air conditioner in spring, one for the furnace in fall — and it excludes parts. A blower capacitor, a clogged condensate line, or a low refrigerant charge found during the visit adds $50 to $300 on top of the base price.
- HVAC maintenance costs $300 a year on average in 2026, ranging $150 to $500 for a two-visit plan.
- A single tune-up visit runs $100 to $250; skipping the off-season visit shifts more wear onto the other unit.
- West Heating & Cooling bundles the spring AC check and fall furnace check into one HVAC maintenance plan.
- Commercial HVAC contracts for restaurants, marinas, and rental properties start around $500 a year and scale with equipment count.
- Filters, capacitors, and refrigerant top-offs are billed separately from the base tune-up price.
Why this matters
A furnace or AC unit that never gets serviced doesn't just fail sooner — it fails at the worst time, usually during the first cold snap or the first 95-degree week at the Lake. Manufacturers tie warranty coverage to documented annual service in most cases, so skipping maintenance can cost more than the tune-up itself if a compressor or heat exchanger fails outside the warranty window.
Homeowners around Camdenton, Osage Beach, and Lake Ozark run their systems harder than most of Missouri — lake houses cycle between vacant and full occupancy, and short-term rentals run HVAC nonstop through peak season. A HVAC maintenance plan that catches wear early is cheaper than an emergency after-hours repair call in July.
How much does HVAC maintenance cost per year?
The number depends on whether you're booking one visit, a two-visit annual plan, or a commercial service contract. Here's how the three break down in 2026:
| Service type | Typical annual cost (2026) | Visits included | Best for |
|---|---|---|---|
| Single tune-up visit | $100-$250 per visit | 1 | Homes running only one system heavily (AC-only or furnace-only) |
| Two-visit maintenance plan | $150-$500/year | 2 (spring AC, fall furnace) | Most Lake of the Ozarks homes with both a furnace and an AC unit |
| Commercial HVAC contract | $500-$1,500+/year | Varies by equipment count | Restaurants, marinas, rental properties, multi-unit buildings |
The two-visit plan is the standard recommendation for a typical residential system — one furnace, one AC unit, one thermostat zone. Homes with zoned systems or multiple units cost more per visit because there's more equipment to inspect.
Single tune-up visit: $100 to $250
A one-time tune-up covers a filter check, coil cleaning, electrical connection tightening, and a refrigerant or combustion check depending on the season. Buy this option if you only need service on one system this year, or you're testing a new HVAC contractor before committing to a plan. Skip it if you own both a furnace and an AC unit — a bundled plan almost always costs less per visit than two separate single calls.
Two-visit annual maintenance plan: $150 to $500 per year
This is the most common HVAC maintenance cost per year for a residential property with both heating and cooling. It includes a spring AC inspection before the cooling season and a fall furnace inspection before the heating season, and most plans include priority scheduling if something breaks between visits.
Buy this option if you run a standard split system (furnace plus AC) and want documented service history for warranty claims. Wait if your system is under 2 years old and still under a manufacturer's included first-year service — check the paperwork before paying for a plan you may already have.
Commercial HVAC maintenance contracts: $500 to $1,500+ per year
Commercial properties scale differently because the cost tracks equipment count, not square footage. A restaurant kitchen with rooftop units and exhaust hoods, a marina building with dehumidification equipment, or a multi-unit rental property all carry higher annual totals than a single-family home. Property managers overseeing several buildings typically move to a service contract rather than booking each property separately, since bundled scheduling cuts down on repeat truck rolls.
Buy a commercial contract if you operate more than one HVAC unit across a property or manage multiple buildings. Skip it if you have a single small commercial space with one rooftop unit — a residential-style two-visit plan may cover it for less.
Why HVAC maintenance cost varies
- Number of systems — a home with a furnace and a separate AC unit costs more to service than a heat pump running both functions off one system.
- System age — older equipment (12+ years) takes longer to inspect and is more likely to need a part during the visit.
- Access and location — attic-mounted furnaces or condensers boxed in by landscaping add labor time.
- Plan structure — a prepaid annual plan usually costs less per visit than booking two one-time tune-ups separately.
- Zoning — multi-zone systems with separate thermostats and dampers require checking each zone individually.
- Commercial equipment count — restaurants, marinas, and multi-unit properties scale cost by unit, not by square footage.
Is an HVAC maintenance plan worth it?
A maintenance plan is worth it for most homeowners because catching a failing capacitor or a clogged drain line during a scheduled visit costs less than an after-hours emergency call. At $150 to $500 a year, the plan typically pays for itself the first time it prevents a mid-season breakdown.
What does an HVAC tune-up include?
A standard tune-up includes a filter check, electrical connection inspection, coil cleaning, thermostat calibration, and a refrigerant check (cooling season) or a combustion and heat exchanger check (heating season). Costs of $100 to $250 per visit generally cover this scope; anything beyond it — like a capacitor replacement — is billed as a separate repair.
How often should you service your HVAC system?
Most manufacturers recommend servicing each system once per season it runs — spring for the AC unit, fall for the furnace — which is why the $150 to $500 annual figure assumes two visits. Systems that run nearly year-round, like heat pumps in mixed climates, sometimes benefit from a mid-season check as well.

FAQ
How much does HVAC maintenance cost per year in 2026?
HVAC maintenance costs $300 a year on average in 2026, ranging from $150 to $500 for a standard two-visit plan covering both the furnace and the air conditioner. Parts replaced during the visit are billed separately.
Is a single HVAC tune-up cheaper than an annual plan?
A single tune-up costs $100 to $250 per visit, which is often more per visit than the per-visit rate on a bundled two-visit annual plan. Homes with both a furnace and an AC unit generally save by booking a plan instead of two separate calls.
What's included in an HVAC maintenance visit?
A standard visit includes filter checks, coil cleaning, electrical connection inspection, thermostat calibration, and a seasonal refrigerant or combustion check. It does not include part replacement, which is quoted separately if something is found.
How much does commercial HVAC maintenance cost?
Commercial HVAC contracts start around $500 a year and can run $1,500 or more depending on equipment count. Restaurants, marinas, and multi-unit rental properties typically sit at the higher end because they run more units.
Does skipping HVAC maintenance void the warranty?
Many manufacturer warranties require documented annual service, so skipping maintenance can void coverage on a compressor or heat exchanger failure. Keeping a service record from a licensed contractor protects that coverage.
How often should a furnace be serviced?
A furnace should be serviced once a year, ideally in fall before the heating season starts. This is one of the two visits included in a standard $150 to $500 annual maintenance plan.
Is HVAC maintenance worth it for a lake house that sits vacant part of the year?
Yes, because a vacant lake house can develop humidity, mold, or frozen-line issues undetected between visits when nobody is on site to notice a failure. A scheduled maintenance visit catches those problems before the next occupied weekend.
One last thing
The $150 to $500 annual range assumes a system in reasonable condition. If your furnace or AC unit is already past 12 years old, ask about the furnace repair cost before committing to another year of maintenance on it — sometimes the math favors replacement over another service cycle. West Heating & Cooling books both residential HVAC maintenance and system replacement quotes for homes around Camdenton, Osage Beach, Lake Ozark, Warsaw, and Lebanon.
