Two ways to reach Mission Peak HVAC for a Fremont system call.

Calls to Mission Peak HVAC during posted hours reach a scheduling coordinator, not an automated menu. The coordinator records your system type (central AC, furnace, heat pump, or duct work), the symptom you are observing, and your equipment age if you know it. That information goes on a dispatch slip that the assigned technician reviews before leaving the shop.

The goal is to arrive prepared. A technician who knows in advance that a 14-year-old Carrier split system is blowing warm air on a 95°F Fremont afternoon can pull the right refrigerant gauges, capacitor test set, and refrigerant recovery equipment before the truck leaves — rather than making a second trip for parts. Preparation is how we keep the average response time at 38 minutes from call to on-site start.

After the diagnostic, you receive a written line-item estimate. Nothing is authorized or started without your signature. That boundary is firm regardless of how straightforward the job appears over the phone.

You do not need to have all of this information — the technician will gather what is missing on-site. But if you can locate it beforehand, the dispatch slip and estimate will be more accurate:

• 01
  System age band

  The year of manufacture is on the data plate near the condenser or air handler. If you cannot find it, an approximate decade is useful.

• 02
  Equipment brand

  Brand name appears on the outdoor condenser cabinet. Carrier, Trane, Lennox, and Daikin are our primary service lines; other brands serviced on confirmation.

• 03
  Last service date

  If you have a previous service record or recall roughly when the system was last serviced, that context shapes the diagnostic sequence.

• 04
  Current symptom in plain terms

  Describe what the system is doing (or not doing) rather than what you think the cause is. "Unit runs but air at the vent is warm" is more useful than "I think the refrigerant is low."
