TL;DR — Too Long; Didn't Read
HVAC revenue swings with the weather. Strong companies price repairs on a flat-rate book, price replacements to a real margin on a project that averages around $7,500 nationally, and build agreement revenue that pays the bills in the shoulder seasons.
- Use flat-rate pricing for repairs so customers know the price before work starts.
- Charge a diagnostic or service fee that covers the trip.
- Price replacements from equipment, labor, materials, permits and overhead to a target margin.
- Offer financing on every replacement.
- Grow agreement revenue to cover slow months.
Bottom line: Price the work properly in peak season, and let agreements carry the slow months.
Hourly billing punishes efficient technicians and makes customers nervous. Flat-rate pricing tells the customer the price before the work starts and rewards a tech who's good at their job.
Flat-Rate Repairs
Build a price book where each repair has a set price based on average time, parts, overhead and margin. Present the price, get approval, then do the work.
Replacement Pricing
Replacement price = (equipment + labor + materials + permits + overhead share) ÷ (1 − target gross margin)
HomeAdvisor puts the national average for installing or replacing an HVAC system around $7,500, with most homeowners paying $5,000 to $12,500. Your price depends on equipment tier, ductwork and access. Don't race to the bottom of that range to win jobs.
Seasonal Capacity
In peak season, your schedule is the constraint. Prioritize agreement members and replacements, and don't discount when you're already full. In the shoulder seasons, use tune-ups and replacement promotions to keep crews productive.
Agreement Revenue
Monthly agreement billing is predictable revenue that arrives whether it's 95 degrees or 60. Contracting Business tied 1,000 agreements to at least $1 million in residential business.
