Appleton HVAC FAQ
Do you serve all of Appleton?
We connect homeowners across Appleton with local HVAC contractors. Coverage depends on which contractors are available that day.
Can I get same-day furnace repair in Appleton?
Sometimes. Same-day depends on contractor schedules, especially during cold snaps. Send a request and we'll check.
Does it matter if I use natural gas or propane?
Yes. Tell us your fuel type (natural gas, propane, oil, electric) so we can match you with a contractor who works on your system.
Who will I be talking to?
Fox Valley HVAC is a referral service. When you send a request, we connect you with an independent local HVAC contractor who serves your area. We don't do the repair work ourselves.
I smell gas. What do I do?
Leave the house right away and call 911 or your gas utility from outside. Don't use switches or phones inside. Call an HVAC pro after the utility says it's safe.
