    Sound Familiar?

    These are the problems hvac business owners tell us about every day.

    1

    Seasonal demand swings make cash flow unpredictable — you are slammed June through September and scraping by in shoulder months.

    2

    Maintenance agreement tracking is a nightmare. You lose renewals because nobody follows up, and that recurring revenue evaporates.

    3

    Your techs waste 30 minutes per call writing up equipment details, refrigerant levels, and warranty info by hand.

    4

    Emergency calls come in at 2 AM and your current system has no way to route them or dispatch the closest tech.

    5

    Customers balk at $8K+ system replacements and you lose the job because you cannot offer financing on the spot.

    Here Is How Kaldr Fixes It

    Every solution is built into the platform. No add-ons, no upgrades, no extra cost.

    Smart scheduling fills shoulder-month gaps with maintenance visits and system tune-ups, keeping your revenue steady year-round.

    Automated maintenance agreement tracking sends renewal reminders 60 days out so you never lose a contract quietly.

    Digital equipment logs let techs snap a photo of the data plate and auto-fill model, serial, refrigerant type, and warranty status.

    After-hours call routing sends emergency jobs to the nearest on-call tech with one-tap accept, so customers are never left waiting.

    Built-in customer financing lets homeowners pay over time while you get paid upfront — no awkward money conversations.

    Frequently Asked Questions

    Does Kaldr handle maintenance agreement scheduling?+

    Yes. You can create service agreements with custom visit schedules (bi-annual, quarterly, monthly), and the system automatically generates and schedules those visits. Renewal reminders go out to customers 60 days before expiration.

    Can my techs log refrigerant usage and EPA compliance data?+

    Absolutely. Technicians can record refrigerant type, amount added, and recovery details on every job. This data is stored per-unit for compliance reporting whenever you need it.

    How does emergency dispatch work after hours?+

    You set up an on-call rotation. When emergency calls come in after hours, the system identifies the nearest on-call tech and sends them the job details. They accept with one tap and the customer gets an automatic ETA notification.

    Can I offer financing on equipment replacements?+

    Yes. Kaldr includes built-in consumer financing. Your tech presents payment options on-site, the customer picks a plan, and you receive the full payment. No chasing invoices on big-ticket jobs.

    Is Kaldr really free? What is the catch?+

    There is no monthly fee. Kaldr earns a small percentage on payment processing when your customers pay through the platform. If you collect payment outside of Kaldr, you pay nothing. We only make money when you do.
