FAQ
Questions about Krefeld HVAC contractor leads
The sample, how fresh the data is and what you pay for.
How many Krefeld HVAC contractors have an email address?
We found a contact email for all 10 in our sample by checking each business's own website. Those are the top-ranked listings, not every business in Krefeld. Across the 380 HVAC contractors we've checked in Germany, we found one for 91%: how that compares by country. Every business in the sample lists a phone number.
How fresh is the Krefeld HVAC contractor data?
The sample above was pulled from Google Maps in July 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 ~48 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.
