How this site is made
Editorial Policy: How We Write and Check This Site
A heating company's website is quoted back at it for years — by customers, by search engines and by AI answers. These are the rules every page here follows.

Short answer
Who writes this site, and how is it checked?
Every page on this site is written by Twin Ports Heating and Cooling from our own work in Duluth, Superior and the surrounding towns. Prices are our published ranges, not estimates. Climate, efficiency-standard and rebate-program facts link to the primary source that states them. We publish no reviews, ratings or testimonials, and any fact the owner has not confirmed is left out rather than guessed. Corrections: call or use the contact page.
On this page
Who writes it
The company does. There are no guest authors, no syndicated articles and no content bought from a writing service. Service pages, guides and blog posts are written from the work we actually do — the failures we see on Twin Ports furnaces, the boilers in the older housing, the propane systems out in the townships — and every page carries the company as its author rather than an invented byline.
We do not publish the names or credentials of individual technicians on this site, and we will not until the owner has confirmed each one. A name a search engine has indexed is hard to take back.
Where the prices come from
Every dollar figure on this site is one of our own published ranges — the $89 diagnostic, the $149 tune-up, and the installed-cost ranges on the pricing page. They describe typical work in the Duluth–Superior market at the time of writing and they are ranges, not quotes; your price is fixed in writing before work starts. Guides and blog posts are checked by script against the same list, so a plausible-sounding number a writer reached for cannot reach a page.
We do not print rebate amounts. Utility programs change their figures, sometimes mid-year, and a stale number is worse than none. The rebates page names each program, links to the utility's own page, and we confirm the current amount at quote time.
Where the facts come from
Local operating facts — which towns have natural gas, what fails on a furnace in a −20°F week, how a Duluth hillside basement changes a job — come from our own service work. General technical and regulatory facts are linked to the primary source that states them: heating-degree-day normals to NOAA's National Centers for Environmental Information, efficiency ratings such as SEER2 and HSPF2 to the Department of Energy and ENERGY STAR, the refrigerant transition to the Environmental Protection Agency, the ended federal tax credit to the IRS, and each utility rebate program to that utility's own page. We only cite a page we have opened and confirmed says what we say it says.
Climate figures — a winter design temperature of −17°F to −21°F and roughly 9,000–10,000 heating degree days a year — are stated once in our content data and reused everywhere, so a number cannot drift between pages.
What we deliberately do not publish
Reviews, star ratings and testimonials. None appear on this site and none appear in its structured data. Self-reported ratings in a website's own markup are not evidence of anything, and we will not print quotes we cannot show you the source of. When we have a body of verifiable reviews we will link to the platform hosting them.
Unconfirmed business facts. Our founding year, technician count, licence numbers, legal entity name and dealer agreements are published only once the owner has confirmed each one. Until then the sentence that would have carried the fact is written without it. The build reports every unconfirmed value each time the site is generated.
Expired incentives. The federal 25C tax credit ended for equipment placed in service after December 31, 2025, and a script fails the build if any page names it as if it were current.
Services we do not offer. We do not offer duct cleaning and we do not refer it; the site says so rather than leaving a searcher to guess.
How pages are reviewed and dated
Every build runs an audit before anything is published: broken links, duplicate titles, questions in FAQ markup that are not on the visible page, figures outside our published list, external links to hosts we have not verified, and any placeholder value that escaped. A failure stops the deploy. Each page shows the date it was last changed, taken from the content itself rather than from the date the site was rebuilt, so "last reviewed" means the words actually changed.
Guides and service pages are revisited when the facts behind them move — a utility renames a program, a standard changes, a piece of equipment we recommended stops being the right answer — and the date on the page moves with them.
Corrections
If something on this site is wrong, out of date, or does not match what you were told on the phone, we want to know. Call (218) 461-1049 or use the contact page and say which page and what is wrong. Genuine errors are corrected on the page, not argued with.
Technical content here is general information for a wide audience and is not a substitute for a licensed technician looking at your specific system; see our terms of use. If you smell gas or a carbon monoxide alarm is sounding, leave the building and call your gas utility from outside.
