The 7 Best CRMs for HVAC Companies (2026)
A no-AC call during a heat wave turns into a booked job in the time it takes a competitor's site to load — most HVAC companies searching for the best CRMs are really trying to solve one thing: a place to keep every lead and customer so nobody gets forgotten.
We build one of these, so we put ourselves first below — but every other pick here gets a genuine strength list and a real, honest catch. We're not going to pretend the others don't work.
- Our pick: SeldonFrame — the whole front office at $29/mo flat (we build it, and we say below when the others win)
- Cheapest real option: HubSpot — free CRM; Starter from ~$15/seat/mo, Professional ~$800/mo + onboarding (has a free plan)
- How to choose: a place to keep every lead and customer so nobody gets forgotten
SeldonFrame
SeldonFrame is more than a CRM — a CRM is just a customer list. SeldonFrame is a whole front office: an AI receptionist that answers calls, texts and chats, a website, a booking calendar and forms, all writing into the same customer list on their own. Most CRMs on this list make you type in every lead by hand; SeldonFrame's agent adds it the moment the customer reaches out. It costs $29/mo flat, and you can build the whole thing free in about 3 minutes before you ever sign up.
For HVAC companies, that means an AC repair booking gets captured and booked automatically — whether the customer calls, texts or fills out a form.
6 more CRMs, ranked
GoHighLevel
from $97/mo (AI Employee add-on $50–$97/mo)A big toolbox for agencies — CRM plus a builder for marketing funnels, made to sell to other businesses.
Best for: Agencies running funnels, email campaigns and multi-client pipelines
- +A huge set of features (funnels, courses, pipelines)
- +Agencies can resell it under their own brand
- +A large library of ready-made templates
Watch out: The AI is a paid extra, not part of the base plan, and costs add up per client — people say it takes 2–4 weeks to really learn.
HubSpot
free CRM; Starter from ~$15/seat/mo, Professional ~$800/mo + onboardingThe well-known, polished CRM built for bigger companies.
Best for: Businesses planning to scale into enterprise-grade marketing and reporting
- +Some of the best reports and CRM detail around
- +The free plan is actually usable to start
- +Connects to a huge number of other tools
Watch out: Jumping from Starter to Professional costs about 40 times more, plus a required ~$3,000 setup fee at that level.
Zoho CRM
from ~$14–20/user/moA deep, customizable CRM that costs far less than the big-company options, part of a 45-app suite.
Best for: Budget-conscious teams wanting deep customization without enterprise pricing
- +Great value for the price per seat
- +Lets you customize a lot and build your own workflows
- +Includes a Zia AI helper on higher plans
Watch out: To get the real value you have to combine several Zoho apps together — it's a toolkit, not a ready-to-go front office.
Keap
from ~$249–299/moA long-running small-business CRM (now owned by Thryv) built around sales pipelines and invoices.
Best for: Established small businesses wanting mature sales automation
- +Well-built marketing automation
- +Invoices and payments built in
- +A long history of onboarding and coaching customers
Watch out: It costs about 3 times more than GoHighLevel's starting price, and features are slowly being folded into Thryv over time.
Pipedrive
from ~$14–24/user/moA CRM built around a visual sales pipeline, for teams that track deals stage by stage.
Best for: Sales-driven teams that want a clean, pipeline-first interface
- +A clean screen built around deal stages
- +Quick for a sales team to learn
- +A solid mobile app
Watch out: It's a sales pipeline tool first — no website, booking calendar or receptionist behind it; AI features cost extra.
Jobber
from ~$39–69/moSoftware for running home-service jobs, with a CRM built specifically for trades.
Best for: Trades businesses managing quotes, scheduling and invoicing for a crew
- +Built specifically for how trades work
- +Quotes, scheduling and invoices all in one place
- +A hub where customers can help themselves
Watch out: It's a job-management tool, not a lead-capture front office — no AI receptionist or website builder.
The closest trades-specific option, but it assumes the lead already called you — it won't answer the phone.

Frequently asked questions
What's the difference between a CRM and a full front office?
A CRM stores leads and customers once you already have them. A front office also captures them — a website, an AI receptionist and a booking calendar that feed the CRM by themselves, instead of someone typing each lead in by hand.
Do I need a CRM if I already use spreadsheets?
Once you start missing follow-ups or losing track of who's who, yes — a CRM's whole job is to make sure a lead never quietly disappears, which spreadsheets don't do on their own.
Is a CRM enough to stop missing leads?
Only if something is reliably putting leads into it. Most missed leads happen before the CRM stage — an unanswered call or an abandoned form — which is why pairing a CRM with an AI receptionist closes the real gap.
What's the best CRM for HVAC companies?
Honestly, it depends on what's already missing. If leads are falling through the cracks between "someone reached out" and "someone followed up," SeldonFrame's combined AI receptionist + CRM + booking is built for exactly that gap. If the need is narrower — just a calendar link, just a CRM, just a form — one of the specialist tools above may be simpler for now.
