When the first cold snap hits, HVAC companies win by triaging calls in a fixed order, dispatching by map, sending live ETA texts and selling the maintenance plan before the tech leaves.
The first cold snap does not call ahead. It shows up on a Tuesday at 5 a.m., and by 7 your phone has 31 missed calls, four voicemails from the same woman, and a text from your best tech saying his kid has a fever. You cannot add techs that day. What you control is the order you run the calls, how fast each customer knows you are coming, and whether each visit turns into a customer for next year. Homeowners read our fall back checklist this morning, so tune up calls are coming too. Here is the cold snap system, built on what is already in House Fly Pro.
Triage: The Order You Run the Calls
Whoever answers the phone needs a fixed order and a script, or the loudest caller goes first. Tape this next to the phone.
| Call | Priority | What you tell them |
| Carbon monoxide alarm sounding, or a gas smell | Emergency, first truck | Leave the house, call the gas utility or 911, then us |
| No heat with infants, elderly or medical needs | First available | You are at the top of the list, ETA text on the way |
| No heat, otherwise healthy household | Same route, by map | Space heater in one room, close doors, we will text an ETA |
| Heat runs but weak, noisy or short cycling | Next open slot | Check the filter, send a photo, quote by text |
| Tune up and maintenance requests | Fill the quiet days | Book it from the calendar with the price upfront |
The two questions that sort every call
“Is anyone in the house under two, over seventy, or on oxygen?” and “Do you have a carbon monoxide alarm, and is it quiet?” Two questions, ten seconds, and the list sorts itself. Write the answer on the job in House Fly Pro so the tech sees it before the first knock.
Dispatch by Map, Not by Who Called First
Three no heat calls in the same subdivision are one trip, not three. On Gold, dispatch with live GPS tracking shows every truck on one screen, so you assign nearby calls to the tech already heading that way. One shared calendar replaces the group chat, and one inbox holds every customer conversation, gate codes included. We wrote the plumbing version of this in our freeze season dispatch guide, and the math is the same: fewer miles, more furnaces, the same number of trucks.
The Live ETA Text That Ends the “Where Are You” Calls
Half of those 31 missed calls were booked customers asking if you are still coming. House Fly Pro sends an on my way text with a live ETA the moment the tech leaves the previous job, and automatic appointment reminders go out before each visit. The customer watches the truck get closer instead of calling the office, and the office answers new calls instead of old ones.
The job timeline the customer can see
From booked, to on the way, to arrived, to done, the customer sees the same timeline your tech does. On a cold snap day, that visibility is the difference between a review that says “they came when they said” and one that says “nobody called me back.”
Quote From the Truck, Get Paid in the Driveway
A tech standing in a basement at 2 p.m. does not have time to call the office for a price. With the price book in House Fly Pro, the common repairs are already there: igniter, flame sensor, capacitor, inducer motor, blower motor, thermostat. Star your top ten as favorites, and a quote by text or email takes under a minute. For the bigger jobs, set the payment choice per job: half up front on a blower motor you have to order, payment on completion for a flame sensor. The invoice carries a pay link, the customer pays by card, Apple Pay or PayPal before the truck is out of the driveway, payouts go to your bank with free withdrawals, and 100% of the tip goes to the tech. The digital job checklist and photo proof keep every repair documented for the callback on Thursday.
Sell the Maintenance Plan on the First Visit
The no heat call is the best sales appointment you will have all year, and most companies waste it. The customer just spent a cold night, they are grateful, and the tech is standing next to the furnace with the panel off. That is the moment to say the plan out loud. In House Fly Pro, recurring services auto rebook and auto charge, so a two visit a year plan is set up once and runs itself: the fall visit books automatically, the reminder goes out, the card is charged after the visit. We covered the pricing in our heating season playbook; here is the 30 second version for the driveway.
- “The part that failed tonight is the kind we catch on a fall checkup. Want me to put you on the plan so this is the last time you meet me at 6 a.m.?”
- “Two visits a year, spring and fall. It books itself and you get a text before each one.”
- “Plan members go ahead of the line on the next cold snap.”
The ENERGY STAR furnace page recommends an annual professional checkup, a useful sentence when a customer asks if the plan is worth it. One in three saying yes on a 40 call day is 13 customers already booked for next fall before you have eaten lunch.
Keep the Crew Safe and Staffed
The tech with the sick kid is going to happen. In House Fly Pro, availability and time off are approved in one tap, so the schedule updates before dispatch starts assigning calls to someone who is not coming. Attics and crawl spaces in freezing weather are real hazards, and the OSHA winter weather page covers cold stress, slips and vehicle safety in plain language. The SOS safety alert covers a tech working alone at 9 p.m., and the app and web portal work in Spanish.
What It Costs for a Five Tech Shop
Everything above except GPS dispatch is on Silver at $19 a month, with three team members included. Gold at $49 a month adds twenty team members, one shared calendar, dispatch with live GPS, automatic review requests after each job, QuickBooks sync and a free transfer of contacts and calendars from Housecall Pro or Jobber. Platinum at $99 covers large and commercial shops with fifty team members, multiple service locations, purchase orders and proposals. Every plan is month to month, 14 days free, no contract, no hidden add ons, two months free on yearly plans, and each extra team member is under $5 a month. Here is the published math for an owner plus four techs, before add ons.
| Owner plus 4 techs | Jobber and Housecall Pro | House Fly Pro |
| Starting monthly price | Jobber $49, Housecall Pro $79 | $49 Gold |
| Four extra team members | About $29 or $35 each | Included, 20 on Gold |
| Monthly total | About $165 to $219 | $49 |
| Dispatch and GPS | Often a higher tier | Included on Gold |
Card processing is standard everywhere. One honest line: House Fly Pro is software. It does not send you the 31 calls. It makes sure you run them in the right order, get paid for every one, and see most of those customers again in the spring.
The cold snap is coming. Have the system ready before the phone rings. Triage, dispatch by map, live ETA texts, quotes from the truck and a maintenance plan that rebooks itself. Start your 14 day free trial and load your top ten repairs tonight.
Frequently Asked Questions
How should an HVAC company prioritize calls during a cold snap?
Run a fixed order: carbon monoxide alarms and gas smells first, then no heat in homes with infants, elderly or medical needs, then other no heat calls grouped by location, then weak or noisy heat, then tune ups in the quiet slots. Ask two questions, about vulnerable people and the carbon monoxide alarm, and note the answers on the job.
Does House Fly Pro include dispatch and GPS tracking?
Yes, on the Gold plan at $49 a month. Dispatch with live GPS tracking shows every truck on one map so you can group nearby calls, and one shared calendar covers the whole company. Silver at $19 includes live scheduling, on my way texts with a live ETA, automatic reminders and one inbox for all customer chat.
How do I sell a maintenance plan on a no heat call?
Offer it while the tech is still at the furnace, and keep it to three sentences: the failed part is what a fall checkup catches, the plan is two visits a year that book themselves, and members go first on the next cold snap. In House Fly Pro the plan auto rebooks and auto charges after each visit.
How much does House Fly Pro cost for an HVAC business?
Silver is $19 a month with three team members. Gold is $49 a month with twenty members, dispatch, GPS, review requests and QuickBooks sync. Platinum is $99 a month for large and commercial shops with fifty members and multiple locations. Every plan is month to month with 14 days free, and extra team members are under $5 a month each.
