We talked to 80+ HVAC owners across Florida, Texas, and California. These are the same pains we heard, over and over.
200 maintenance contracts coming due in 30 days. Your office manager is in Excel until midnight three nights a week.
60% of your customers prefer Spanish. ServiceTitan and Housecall Pro are English-only. So you DIY: WhatsApp + handwritten receipts.
Customers call 5x/day asking for receipts, invoice copies, payment status. No self-serve portal — the office becomes a call center.
Cards expire, get re-issued, run out. Failed payment dunning is manual (or worse, ignored). You leak $800–$2,000/mo in silent churn.
Quote came back at $2,400/month + $5,000 setup + 12-month contract. For a 12-person shop, that's insane. You bail.
QuickBooks does accounting. But recurring billing? Customer portal? Dispatch? You bolt on 5 tools. None talk to each other.
Built around the recurring maintenance contract — the heart of every healthy HVAC business.
Annual / semi-annual / quarterly contracts auto-renew, auto-invoice, auto-charge. Customers get bilingual reminders 30 days before.

"We were paying $2,400/month for ServiceTitan and using maybe 30% of it. Switched to RentingOS in 4 days. Our admin team in Miami can finally use it in Spanish. Best business decision we made in 2026."
