Peak-season playbook

How should an HVAC company
handle calls in a heat wave?

Prepare before the heat arrives, because a heat wave is too late to fix your phones. Set your on-call list and overflow plan early, decide who goes first, and tell every caller an honest wait time. Then call back anyone you missed, and review what happened once it cools down.

Last updated October 31, 2026

Before the season starts

  • Write down your on-call list, in order, with a backup for every tech.
  • Decide where calls go when all your lines are busy.
  • Test your call forwarding from a phone outside the office.
  • Fill the schedule with tune-ups early, so fewer systems fail at the worst time.
  • Agree the triage order below with everyone who answers the phone.
  • Prepare a short message for your website and voicemail saying you are busy but answering.

Who goes first

When calls outrun your techs, someone has to wait. Decide the order now, so nobody has to invent it under pressure.

  1. 1Any gas or carbon monoxide concern: safety script first, always.
  2. 2Homes with a baby, an older person or anyone with a medical condition, and no cooling.
  3. 3Systems that are completely down.
  4. 4Systems that are running but struggling.
  5. 5Routine work, moved to make room if the customer agrees.

During the rush

  • Give an honest wait time. If you don't know one, say when you'll update them.
  • Send a text once a job is confirmed, so callers don't ring back to check.
  • Tell people on the wait list to call back if things get worse.
  • Offer simple advice while they wait, such as closing blinds and moving to the coolest room.
  • Keep one person focused on the phones if you can. Rotating them burns people out.
  • Never promise an arrival time you don't have.

After it cools down

  • Call back every missed caller, starting with the oldest.
  • Check which hours you missed the most calls.
  • Ask your techs and office what broke, and fix it before the next one.
  • Update your on-call list and your triage order.

FAQ

Common questions

Can't find your answer? Book a 15-minute call — we reply within one business day.

What should I do when every line is busy?

Forward overflow calls to someone who can answer, rather than letting them ring out. VoiceBridg can take those calls, so the caller doesn't try the next company.

How do I decide which calls go first?

Safety first, then homes with vulnerable people and no cooling, then full outages, then partial problems, then routine work. Agree the order before the season.

Should I stop booking routine work in a heat wave?

Not necessarily. Keep booking it, but tell the customer it may move, and get their agreement if it does.

What should I tell a customer who has to wait?

Give an honest window, or a time you'll update them. Ask them to call back if anything changes or anyone feels unwell.
