HVAC Maintenance Plan Value Calculator

Service plans bundle tune-ups with repair discounts and perks. Enter the plan’s price and your own numbers to see whether it saves you money.

Method reviewed October 26, 2026. Version 1.0.0. How it works

Your inputs

From the contractor’s offer. All amounts here are example values — enter your quotes.

DOE suggests a professional check of the cooling system in spring and the heating system in fall.

Only count visits you would pay for without a plan — a plan visit you would not otherwise book has no value to you.

For example waived after-hours fees you expect to use. Leave 0 if unsure.

Result

Plan pays for itself

Yearly saving with the plan
$85.00

At these numbers the plan saves about $85.00 a year.

  • Whatever you decide, change or clean filters regularly — ENERGY STAR suggests checking them monthly — and keep the outdoor unit clear. Read the plan’s terms for what counts as a covered repair.
Yearly cost without the plan

Yearly cost with the plan (after benefits)

Show the working
  1. Without plan = tune-ups × price + repairs
    2 × $120.00 + $300.00 = $540.00
  2. With plan = fee + extra tune-ups + repairs × (1 − discount) − other benefits
    $200.00 + 0 × $120.00 + $300.00 × 0.85 − $0.00 = $455.00
  3. Break-even
    The included tune-ups and benefits already cover the plan price.

How the comparison works

Without a plan you pay for the tune-ups you would book anyway, plus repairs at full price. With the plan you pay its fee, any tune-ups beyond those included, and repairs less the plan discount, minus any other benefit you would otherwise pay for.

The break-even figure is the yearly repair spending at which the discount covers the part of the fee that the tune-ups do not. Count only visits you would really buy — an included visit you would never book is worth nothing to you.

Maintenance matters either way

The U.S. Department of Energy suggests having a professional check the cooling system in spring and the heating system in fall, and ENERGY STAR suggests checking filters monthly and changing or cleaning them as needed. A plan is one way to make sure that happens; booking the visits yourself is another. Read what a plan covers — some exclude parts, refrigerant or after-hours calls.

Worked example

These are the example values the calculator opens with, and the result the engine calculates for them.

Inputs

Plan price per year
200 $
Tune-up visits included per year
2
Price of one tune-up without the plan
120 $
Tune-ups you would buy anyway
2
Expected repair spending per year
300 $
Plan discount on repairs
15 %
Other plan benefits you value (per year)
0 $

Result

Yearly saving with the plan
$85.00
Yearly cost without the plan
$540.00
Yearly cost with the plan (after benefits)
$455.00
Repair spending needed to break even
$0.00

At these numbers the plan saves about $85.00 a year.

Assumptions

  • Only tune-ups you would buy anyway are counted as plan value; repairs are discounted by the plan percentage.
  • All prices are your inputs; the defaults are examples, not market prices.

Limitations

  • Repair costs vary greatly from year to year; use an average over several years.
  • Benefits such as priority scheduling have value that is hard to price; add them under other benefits only if you would pay for them.

Frequently asked questions

Are HVAC maintenance plans worth it?

When the included visits cost less than buying them separately, yes — the discount is a bonus. When they cost more, the plan pays only if you expect enough repairs. The calculator shows which case you are in.

Does skipping maintenance void my warranty?

Some manufacturer warranties require proof of regular maintenance. Check your warranty terms and keep receipts.

Why are the default prices so round?

They are example values, not market prices. Enter the quotes you have received.
