How to get help with HVAC questions


Some examples of customer concerns addressed by the HVAC Experts on JustAnswer include:


  • Why does my furnace not kick on when the thermostat is set to a temperature above the ambient temperature of the room?
  • What would you suggest as a replacement brand and tonnage for my York heat pump’s outside unit?
  • My Bryant 90 Plus furnace is not heating. The exhaust fan comes on and goes off, but the furnace does not ignite.
  • How do I remove a thermostat schedule and return it to manual mode?

Before reaching out for HVAC assistance, be prepare to answer these questions:


  • What are the issues you’re experiencing
  • Have you confirmed that the fault isn’t in your thermostat settings?
  • Have you changed your filters recently?
  • Do you intend to do the job yourself?

Keeping these questions in mind will save you valuable time as you seek the resolution you need.
