FAQ

Questions about Duisburg HVAC contractor leads

The sample, how fresh the data is and what you pay for.

How many Duisburg HVAC contractors have an email address?

We found a contact email for 25 of the 30 in our sample by checking each business's own website. Those are the top-ranked listings, not every business in Duisburg. Across the 380 HVAC contractors we've checked in Germany, we found one for 91%: how that compares by country. Phone numbers are listed for 26 of the 30.

How fresh is the Duisburg HVAC contractor data?

The sample above was pulled from Google Maps in September 2026. Your own export runs the search when you start it, so it lists what Google Maps shows that day — results stream into a live table as they're found.

What if Google Maps lists fewer than ~110 HVAC contractors?

You only pay for what's delivered: 1 credit per business. A scrape reserves its worst case up front and automatically refunds whatever it doesn't use, and a failed job refunds in full.
