Who writes this

Gary Musaraj owns and runs Jupitair HVAC and is the technical source for everything published here. The trade details — what fails, what it costs, what a repair actually involves — come from working on these systems in Plano and the surrounding North Texas cities since 2008.

Every price, code reference and efficiency standard on this site is checked against the source that issues it before it goes live, and re-checked when that source changes.

How AI is used here

Plainly: AI tools are used to research and draft articles on this site. They are not used to decide what is true. Drafting is the easy part of writing a guide about heat pumps; being right is the hard part, and that is where the process below is aimed.

There is a specific reason we do not let an AI model check its own facts. In August 2026 we tested four current models on a sample of our own published copy that contained a known error — we were still telling homeowners about a federal tax credit that Congress had ended. Asked to audit the passage from memory, none of the four caught it, and three of them confidently confirmed the wrong version. Given the actual IRS guidance to read, the same models found the error immediately.

So claims about tax law, refrigerant rules, efficiency standards, permits and licensing get checked against the primary source — the IRS, the EPA, the Department of Energy, the TDLR, the relevant building code — not against what a model remembers.

Where the prices come from

Every price range on this site is stored once, in a single file, and every page reads from it. An automated check runs against the whole site and fails the build if any page quotes a figure that disagrees with it. That check covers the after-hours fee, compressor replacement, capacitor replacement, and the review count shown in our star rating.

This exists because it had already gone wrong. An earlier audit found compressor pricing stated eight different ways across the site, and three different review counts in three different places. Ranges are ranges — your house, your equipment and your ductwork decide where you land in one — but the number should not change depending on which page you opened.

What we will not publish

• Competitor review counts or star ratings. We checked ours against the sources once and found every verifiable figure wrong, so we removed them rather than republish numbers we could not stand behind.
• Invented statistics, or a precise-sounding figure where the honest answer is a range.
• A rebate, tax credit or incentive presented as available without confirming it still is. These expire, and expired ones are the single most common way a home-services site misleads a buyer about the real cost of a job.
