Blog Opinion

Heating season is here. An HVAC company's best leads are already in its customer list.

For most HVAC companies, a CRM pays for itself on repeat work, not new leads: equipment records, tune-up reminders and fast follow-ups on the customers you already have. Most small shops should start with an HVAC-ready field service app; Salesforce fits once you've outgrown one.

First post in my weekly trade series: one trade, how it could actually use a CRM, and the tools around it. This week: HVAC, because the furnaces just switched on.

Here's my view up front. Most HVAC companies shop for software to get new leads. But the cheapest job you'll book this winter is a customer who already trusts you, owns a 14-year-old furnace, and hasn't heard from you since the spring tune-up. A CRM's real job is to make sure that customer hears from you first.

The facts

  • Winter bills are moving in different directions. The US Energy Information Administration's Winter Fuels Outlook (October 7, 2026) expects homes that heat with electricity, "more than 40% of homes," to see bills rise 4% on average, and heating-oil homes (about 3%, mostly in the Northeast) to spend 21% more. Natural gas homes should spend 9% less and propane homes 3% less. EIA assumes a much colder West and flags a strong El Niño that "could lead to large temperature variations" (EIA Today in Energy; Winter Fuels Outlook).
  • The refrigerant rules changed again. EPA's final rule (published May 26, 2026, effective July 27, 2026) removed the installation deadline for residential and light commercial AC and heat pump systems built entirely from components made or imported before January 1, 2025. New systems from newer components still need a refrigerant under 700 GWP, and repairs of existing R-410A systems remain allowed (Federal Register; EPA restrictions by sector). Translation: knowing which refrigerant each customer's system uses matters more in "repair or replace?" talks.
  • AI receptionists now know who your members are. ServiceTitan's help page for its AI Voice Agent (updated October 22, 2026) says it can recognize customers with an active membership and "books eligible jobs against Recurring service events instead of one-off jobs." It's billed on usage, and "all calls, regardless of their outcome," count (ServiceTitan Help).
  • Prices I checked on October 27, 2026 (US$). Jobber starts at $29/month billed annually for one user, its Receptionist add-on is $29/month and Pipeline is $49/month (Jobber pricing). Housecall Pro's Basic plan is $59/month billed annually; recurring service plans are on its MAX plan, which had no price on the page (Housecall Pro pricing). ServiceTitan doesn't publish prices (ServiceTitan pricing). Salesforce Starter Suite starts at $25 per user per month (Salesforce small business pricing), and Field Service Technician or Dispatcher licenses list at $175 per user per month billed annually (Salesforce Field Service pricing).

Penny's take: work the list you already have

Penny's take

New leads cost you ad money. Your old customers cost you a reminder. An HVAC CRM earns its keep on the second one.

Here's how I'd set up a CRM for an HVAC company, in plain terms.

Diagram, Penny's opinion: the HVAC customer loop. Step one, a call or web request is logged with the source. Step two, the job is done and the equipment is recorded: type, age and refrigerant. Step three, a review request goes to every customer. Step four, fall and spring tune-up reminders go out. Step five, a repair-or-replace conversation happens before the system fails. The loop then returns to the next call.
The HVAC customer loop. Every step lives in the CRM, so nobody has to remember it.
  • Leads. Every call, form and ad lead gets a record with its source. When you later ask "where did my good jobs come from?", you'll have an answer that isn't a guess.
  • Follow-ups. Unsold estimates get a reminder in two days and again in a week. Big replacement quotes are where most of the money leaks, so they get a named owner.
  • Job pipeline. Simple stages: new, estimate sent, won, scheduled, done, paid. If it needs a legend, it's too fancy.
  • Equipment and repeat work. This is the HVAC superpower. Record the unit type, install year and refrigerant on every visit. Then the CRM can list "gas furnaces over 15 years old with no tune-up this year" and remind you before the cold snap, not after.
  • Reviews. Ask every customer after the job, not just the happy ones. Google's rules don't let businesses "selectively solicit positive reviews" or offer incentives for them (Google Maps content policy). Automate the ask; don't filter it.

Which tool, honestly

For a typical 1 to 10 person residential shop, I'd start with an HVAC-ready field service app: Jobber, Housecall Pro or ServiceTitan. They bundle scheduling, quotes, invoices and payments with the customer list, and that's most of the job. Salesforce is the better fit when you run several locations, sell commercial service contracts, have a dedicated sales team chasing replacements, or need it to talk to an ERP. Plenty of shops never get there.

Around the CRM: ads, invoices and AI phones

  • Ads. Google Local Services Ads charge per valid lead, including some missed business-hours calls where the caller stays on the line over 20 seconds (Google LSA Help). Tag those leads in your CRM so you can compare cost per booked job, not cost per call.
  • Invoices and quotes. Use what your field service app has built in, and sync it to QuickBooks or Xero. Jobber, for example, lists card processing at 2.9% + 30¢ online.
  • AI receptionists. Worth a test for after-hours and overflow calls in a no-heat week, if it can book into your real calendar and knows your members. One that only takes messages just moves the voicemail.

Where the other side has a point

The strongest objection: "My techs won't fill in equipment fields." Fair. A CRM full of blanks is a pricey address book. Keep it to three required fields (unit type, install year, refrigerant) and make them part of closing the job. Also, outbound reminders aren't free: texting and calling customers has consent rules, so check them before you automate.

Tie it to getting found by AI

Your website is the other half of the list. When someone asks an AI "who services heat pumps near me?", it can only recommend what it can read. Say which systems you service, your area and your hours in plain text, and mark up the business as an HVACBusiness, a type schema.org defines. Add the same services to your Google Business Profile (Google Business Profile Help).

What to do this week

  1. Export your customer list and sort it by last service date. Anyone not seen since spring gets a tune-up reminder.
  2. Add three equipment fields to your job form: unit type, install year, refrigerant.
  3. Set two estimate follow-ups (day 2 and day 7) in whatever tool you use.
  4. Send a review request after every job, to everyone.
  5. Check your website lists your services, area and hours in plain text.
