About Before You Call a Pro

Before You Call a Pro helps you work out what is wrong with a home system or appliance, and whether you can fix it safely yourself. Each guide starts with the checks most likely to solve the problem. It shows where do-it-yourself work stops, and it tells you which kind of professional to call when it does.

The guides cover heating, cooling, water heaters, plumbing, thermostats and major home appliances. They are written for homes in the United States.

What you get here

• A quick answer first, then the likely causes in the order worth checking.
• Step-by-step checks with the tools and time each one needs.
• Safety warnings placed before the steps they apply to, not at the bottom of the page.
• A "When to call a pro" section that names the trade to call and what to tell them.
• Numbered citations to the manufacturer manuals and official safety pages behind each claim.
• Free tools: diagnose questions, a repair-or-replace calculator, error-code tables and printable checklists.

Who runs the site

Before You Call a Pro is an independent site run by one person, Evrenus Fırat Polat, from Kocaeli, Türkiye. Evrenus is the founder and the site's Editor & Researcher. Evrenus is also a software developer with more than seven years of full-stack experience and builds the site's diagnostic tools.

There is no staff, no team of technicians and no outside writers. When a page on this site says "we", it means the site and its editor.

Evrenus is not a licensed technician and does not test products or repairs. That is why every guide is checked against manufacturer documentation and official safety guidance, and why every guide says plainly where the safe homeowner checks end. You can read more on the author page for Evrenus Fırat Polat or on LinkedIn.

How the guides are made

We collect the sources first: manufacturer manuals and support pages, and guidance from government agencies and safety organizations. Guides are then drafted with AI assistance from those sources. Each draft goes through a separate review against the sources, a safety pass and automated checks before it can go live.

That review is also AI-assisted. No licensed technician writes, tests or reviews the guides. The full process, the rules for sources and the review cycle are on our methodology page.

How the site makes money

The site is free to read.

Today it shows no ads, has no affiliate links and earns no money from its pages. If we add ads or affiliate links later, this section and our privacy policy will describe them before they start.

No company pays to be mentioned, and we publish no sponsored posts, guest posts or paid placements. Read how we choose parts and tools.

What we don't do

• We don't test products or repairs ourselves, and we never claim to. There is no workshop and no test lab.
• No local repair services, no "near me" pages and no paid referrals to technicians.
• No product reviews, star ratings or "best product" lists.
• No personal repair advice by email. We can't see your appliance, so a licensed professional on site is the right next step when a guide doesn't solve the problem.
• No accounts, sign-ups or newsletters.
