Bookkeeping for HVAC Companies
HVAC businesses run on a mix of seasonal demand, recurring maintenance agreements, and capital-intensive equipment installs — a financial model that's hard to manage without the right bookkeeping structure. Simple Books Now organizes your revenue streams, tracks your real costs per job, and puts Luisa's Enrolled Agent tax expertise to work so your business isn't just surviving slow season — it's building toward something.
Book a Free ConsultationFew trades have a more volatile cash flow pattern than HVAC. Summer and winter bring installation and emergency-call spikes, while spring and fall can feel like a different business entirely. Maintenance agreements smooth that revenue, but only if they're priced correctly — which requires knowing your true cost to service each agreement, including refrigerant, filters, and technician time. Without job-level bookkeeping, HVAC owners routinely under-price agreements and wonder why profitable-looking revenue doesn't translate to cash in the bank.
Luisa's Enrolled Agent credential adds a dimension that a standard bookkeeper can't offer. HVAC businesses have significant depreciation opportunities — service vans, refrigerant recovery equipment, vacuum pumps, manifold gauges, and diagnostic tools all qualify for deductions that need to be planned strategically. Section 608 refrigerant regulations also create record-keeping requirements that intersect with your books. And if you're selling and installing new systems, Florida's sales tax rules on installed HVAC equipment are specific enough that a mistake can trigger a Department of Revenue audit. Luisa knows this territory.
The Financial Challenges We Solve
Seasonal Revenue Swings & Cash Flow Gaps
A $40,000 July doesn't help you make payroll in March if you haven't set aside the right reserves. We build a monthly financial picture that accounts for your seasonal pattern so you're not caught off-guard during slow season and you're not spending summer cash that should be covering Q1 of next year.
Maintenance Agreement Revenue Recognition
When a customer pays upfront for a year-long maintenance agreement, that's not all income on day one — it's deferred revenue that should be recognized as you perform each visit. Booking it incorrectly inflates your income in the sale month and understates it later, creating misleading financials and potential tax timing problems.
Refrigerant Cost & Regulatory Tracking
R-22 phase-out and refrigerant cost volatility make refrigerant one of your most expensive and complicated line items. We track refrigerant purchases and usage at the job level so you can see your true cost per unit serviced and ensure your documentation meets EPA Section 608 record-keeping requirements.
Multi-Truck Fleet Cost Allocation
When you're running four or five service vans, vehicle costs — fuel, maintenance, insurance, registration — need to be tracked per vehicle and allocated fairly to get a true picture of your operating overhead. We set up your fleet tracking so vehicle costs are captured completely and depreciation is planned, not forgotten.
Equipment Sales vs. Service Revenue Separation
Selling and installing a new $8,000 system has a completely different margin profile than a $150 service call. When both are lumped as "HVAC revenue," you lose the ability to know which part of your business is driving profit. We separate install revenue, service revenue, and maintenance revenue so you can make informed decisions about where to grow.

Florida's sales tax rules for HVAC installation depend on contract type. Under a lump-sum contract, you generally pay tax on your material cost but don't separately charge the customer sales tax on parts. Under a time-and-material contract, you charge sales tax on materials. Getting this wrong can trigger a DOR audit. Luisa helps you structure your contracts and invoicing so you're compliant from the start.
A customer deposit is a liability — not income — until you deliver the equipment or perform the service. Recording it as income the day you receive it overstates your taxable revenue for that period. We set up your books to hold deposits in a liability account and recognize revenue correctly when the install is complete.
Yes, supplies used in your HVAC work are deductible business expenses. For van stock you replenish regularly, we track purchases as inventory or supplies depending on your volume, ensuring the deduction is captured in the right period and your job costing reflects actual refrigerant and supply costs per call.
Yes — you can reimburse employees for business use of their personal vehicles using the IRS standard mileage rate, and that reimbursement is deductible for your business and tax-free for the employee if documented correctly. Without proper mileage logs, the IRS can disallow the deduction. We'll help you set up a reimbursement policy and documentation process that holds up.
HVAC technician pay often mixes hourly base pay with spiff bonuses for sold maintenance agreements or accessories. Each component is handled differently on payroll from a withholding and deduction standpoint. We work with your payroll setup to make sure bonuses are processed correctly and your payroll records match your job-cost records.
