Repair or Call exists for a specific moment: something in your house has stopped working, you do not know whether it is a $30 problem or a $6,000 problem, and the first three search results are trying to sell you a new system before they tell you anything.
Every guide here is built to be read standing in front of the equipment, on a phone, with the panel already off. Answer first, then the diagnosis in order of probability, then an honest cost range, then a clear line marking where a homeowner should stop.
What we cover
Four areas, chosen because they are where homeowners face the largest information gap against the person quoting them: gas furnaces, water heaters, residential air conditioning, and the big-ticket home repair costs — roofing, HVAC replacement, and the rest of the decade-scale expenses.
We do not cover general contracting, remodels, or anything decorative. Narrow and deep beats broad and thin, particularly when the subject is combustion safety.
Who writes it
Articles are written and reviewed by working tradespeople, not generalist copywriters. Our lead author, Mike Kovacs, has spent twenty years on residential HVAC service calls and holds EPA 608 Universal certification and a state gas-fitting license. Pricing comes from real invoice history and quotes collected across multiple US metro markets, refreshed annually.
The full method — sourcing, review, and update cadence — is written out on our editorial policy page.
How this site makes money
Three ways, all disclosed. Display advertising on article pages. Referral fees when a reader chooses to request quotes from a contractor network. And affiliate commissions on tools and parts we link to, covered in detail in our affiliate disclosure.
None of those revenue streams buys placement, wording, or a recommendation. No manufacturer, contractor, or network sees an article before it publishes, and no one pays to be named in one. When the right answer is "do not repair this, and do not replace it yet either," that is the answer you get — it just happens to be the one that earns us nothing.
What this site is not
It is not a substitute for a licensed contractor, and it is not an authority on your local code. Gas piping, refrigerant handling, and line-voltage work are regulated in every US state for good reasons. Where a job crosses that line, we say so in the article rather than leaving you to find out on the way to the emergency room.
