Negative keywords for HVAC companies
HVAC search is flooded with certification seekers, filter-size lookups and window-unit shoppers. This list keeps your budget on repair and install intent.
Updated
Before you paste: what NOT to block
Don't block the money queries that merely look generic:
- ac repair near me
- furnace not working
- hvac replacement cost
- emergency ac repair
Every list on this page is a starting point, not a decree. Scan it against your own offer before applying — one business's junk click is another's best lead.

View listFrequently asked questions
Why block "window ac unit" and "portable air conditioner"?
Those are product searches — someone buying a $150 box at a big-box store, not booking a $6,000 install. Unless you retail units, they only cost you money. "AC installation" and "ac replacement cost" stay unblocked.
Is "hvac parts" safe to block?
For service-and-install companies, yes: parts searchers are DIYers or techs. If you run a parts counter, drop that term and the b2b-and-wholesale list from this page before pasting.
These are generic industry negatives - safe in most accounts of this kind, but not tuned to yours. Inside Keyword Ninja, the Smart Blocklist cross-checks this exact catalog against your real search terms and shows the wasted spend before you block a single word.
