Heat pump tune up
A heat pump heats and cools, so its tune-up has to check both modes and the parts an AC does not have.

The short version
A heat pump tune up covers everything in an AC tune-up, plus the parts that make heating work: the reversing valve, the defrost control, the backup or auxiliary heat and the system in both modes. Because it runs most of the year, many owners book a check before both cooling and heating seasons.
Safety first: refrigerant and line voltage
Two parts of this job are regulated or dangerous, so they come first.
EPA counts even attaching gauges to measure pressure as work that needs a certified technician.
Capacitors can hold a charge after the power is off. Leave panels and wiring to a licensed contractor.
What a heat pump tune-up adds
Over a standard AC visit.
It switches the system between heating and cooling.
See defrost cycle.
So they come on only when needed.
A wrong setting can run expensive backup heat too often.

One visit or two?
ENERGY STAR advises checking cooling in the spring and heating in the fall. A heat pump does both jobs, so two shorter visits, or one visit before your harder season, both work. In cold climates the fall visit matters more because defrost and backup heat are tested before winter.
What it saves
DOE's 2018 review of 44 field studies put the extra savings from tuning up existing AC and heat pump systems at about 5%. The bigger value is finding a failing part before a cold snap. For the full AC checklist see air conditioner tune up.
What drives the price of heat pump tune up
HyreHVAC does not publish a price for heat pump tune up. We do not yet hold enough sourced, dated quotes to give a figure we can stand behind.
The number of visits per year, the system type (ducted or ductless), and whether it is part of a plan are the main drivers.
Our HVAC cost guides explain each driver, and the HVAC maintenance calendar lets you work through your own numbers.
What happens after you ask
You fill in the HVAC options form with the job and your zip code. HyreHVAC is a publisher, not a contractor, and contractor matching is still being built. Until it is, treat the form as an inquiry. Keep getting your own written quotes and check each contractor’s licence with your state board.

Tell us about the work
Three short steps: the job, your home, and how to reach you. Nothing goes to an HVAC company unless you agree.
A person reads it and replies, free and with no obligation. Matching is not live yet, so this is not a quote. If you smell gas or a CO alarm sounds, leave the house and call 911 or your gas utility first.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the federal microdata file, the statute or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify.
The counts below are generated from the published pages themselves, last counted November 12, 2026, and they are what we have actually published rather than what we intend to.
- 18
- studies published
- 15
- federal sources read and cited
- 15
- studies published with their full dataset as CSV
- 51
- jurisdictions reproduced against EIA’s own tables
How this desk works
- Primary sources only. Federal data comes from the agency that collects it, in the file that agency publishes. We do not cite an article that cites a source; we download the source and compute the figure ourselves.
- We validate against the agency before we publish. First, we use each federal microdata file to reproduce the agency’s own published tables. Our cooling research reproduces EIA’s state estimates and standard errors for all 51 jurisdictions. That check caught a variance formula that was off by a factor of four.
- Every estimate carries its uncertainty. These are survey figures, not counts. Standard errors are computed from the replicate weights the federal file supplies and printed beside the estimate. An estimate too imprecise to publish is reported as such rather than printed.
- Nothing is typed by hand. Prose, tables and charts all read from one dataset built by script, so a number in a sentence and the same number in the table below it cannot disagree.
- We publish the data, not just the conclusion. 15 of our 18 studies offer the full computed table as a CSV download on the page, so you can check the analysis or disagree with it. A study without a row-level dataset gets no download link and claims none in its structured data.
- We correct in public. Where we have published a figure wrongly we fix the figure, rewrite any analysis that rested on it rather than patching the number underneath it, and leave a dated correction note on the page.
- We do not install or sell HVAC equipment, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of October 26, 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreHVAC is a publisher. We do not install, repair or inspect HVAC equipment and hold no contractor licence. Nothing here replaces an on-site diagnosis by a licensed contractor. Sources are cited with the date they were checked.
