Who it picked instead

The company the assistant picked most often in Fontana.

NexGen HVAC & Plumbing

Picked first in 5 of 6, picked in 5 of 6

“Its site advertised 24/7 emergency service, broad heating and cooling services, and online scheduling.”

What would change it

Where the assistant found the answer on another site and not on this one.

  • The market answer identified NexGen's online scheduling and 24/7 emergency claim as reasons to rank it first; 4 Points advertises 24/7 emergency service and says to book online, but the booking path is presented as a contact form.

  • The market answer passed on 4 Points for the upfront-pricing question because reviewed Fontana heating pages did not publish repair prices.
