What buyers evaluate, and how to prepare

Can the business legally operate and pull permits without you?
Deal-critical
License Coverage

What buyers determine

Buyers are underwriting day-one legality and downtime risk. If the contractor license and permit pulling sit with the owner, installs can stall while a new qualifier gets approved, permits get delayed, and inspections get missed. They also want to confirm your licensing matches the work you sell (service, changeouts, light commercial) in every city and county you operate in.

How to prepare

  • Map required licenses by trade and jurisdiction, and list who currently holds each one
  • Write down your permit workflow, including who pulls permits and who meets inspectors
  • Create a qualifier continuity plan with a named internal candidate or an external hire timeline
  • List subcontracted scopes (electrical, plumbing, crane) and the key terms you rely on
Great answer
We operate in three counties. The contractor license is held by our service manager, and permits are pulled by our office admin under his license. If he left, our lead installer is eligible to qualify in about 90 days based on state requirements, and I’m willing to stay on as qualifier during that window so installs don’t pause.
Good answer
I currently hold the license, but we’ve identified a lead tech who’s on track to qualify, and we know the state timeline. I’m open to staying on short-term so permitting stays uninterrupted.
Red flag
I’m the qualifier and I handle permits. We’ll figure out the licensing part after the sale.
How Rejigg helps:Rejigg’s built-in data room lets you share license documents, permit examples, and your qualifier plan in one place, with controlled access.
Can you show clean financials and job-level margin that match how the shop actually runs?
Deal-critical
Clean Financials

What buyers determine

Even in HVAC, where operations matter a lot, deals still fall apart when the numbers don’t tie out. Buyers want to see repeatable profit and whether replacement margins hold up after you include callbacks, warranty labor, and discounting. If an SBA lender is in the deal, messy books become a timeline problem because the bank will ask for backups until it reconciles.

How to prepare

  • Reconcile your profit and loss statements to tax returns, and note any differences
  • Split revenue and gross margin the way you actually manage the shop (service, replacement, commercial)
  • Track owner add-backs with receipts and a one-line reason for each
  • Code callback and warranty labor to job numbers so replacement margins are credible
Great answer
Our books split revenue into residential service, residential replacement, and commercial service and maintenance. Replacement runs at 42% gross margin before callbacks and about 38% after warranty labor, which we code back to job numbers. Here are the last two years of profit and loss statements tied to the tax returns, plus a short add-back schedule with documentation.
Good answer
We have accurate profit and loss statements and can break out service versus replacement revenue. We’re still tightening up job costing and callback coding, but we can show the trend and explain what’s included.
Red flag
Everything runs through one income line and I don’t really track margins by service line. My accountant can explain it if needed.
How Rejigg helps:Rejigg’s QuickBooks integration speeds up data collection, and the secure data room keeps lender-ready documents organized without email chains.
Is your membership base real, active, and actually getting serviced on schedule?
Deal-critical
Membership Quality

What buyers determine

Buyers treat memberships as proof you own the installed base and can smooth out shoulder seasons. A big count does not help if customers are lapsed, overdue, or signed up on a promo that never renews. They also want to see that you can deliver the visits without wrecking peak-season capacity or pushing members out six weeks.

How to prepare

  • Define ’active’ as paid and in-force today, then report active vs lapsed over the last 12 months
  • Show visit completion by customer: last service date, next scheduled date, and percent receiving both annual visits
  • Break down monthly pay vs annual pay, plus member average ticket vs non-member
  • Track how many replacements came from member households over the last 6–12 months
Great answer
We have 1,420 active memberships today, and 86% received both visits in the last 12 months. Renewal runs at 79% annually, and the top cancellation reason is moving out of area. Member households average $612 per service visit versus $410 for non-members, and 48% of our replacements last year came from member homes.
Good answer
We know our active count, and we can show renewals. We’re still improving visit completion tracking, but we can pull last service dates and see who is overdue.
Red flag
We have a big club list in the software. I’m not sure who’s actually active or current on visits.
How Rejigg helps:Rejigg lets you upload membership reports and service-completion snapshots so buyers can validate the base without endless follow-ups.
Are callbacks and warranty work quietly eating your install margins?
Deal-critical
Install Quality

What buyers determine

Callback rate is a quick HVAC truth test because it shows install quality, training, supervision, and documentation. Buyers want to understand whether today’s margins are stable or whether they are paying for problems that show up as free labor later. They also listen for whether you track root causes and fix them, instead of just absorbing the cost.

How to prepare

  • Pull 6–12 months of callbacks and warranty tickets, and categorize them by cause
  • Tie callbacks to job numbers and, if possible, to crews or lead installers
  • Document process controls like startup sheets, install checklists, and supervisor inspections
  • Explain how manufacturer warranty reimbursements work and how often you actually collect them
Great answer
Over the last 12 months, our callback rate within 30 days was 3.2% on replacements. The top causes were drain issues and airflow, so we added a startup checklist and a supervisor check on duct transitions for changeouts. Here’s the callback log by job number, plus the warranty labor we coded so you can see the margin impact.
Good answer
We track callbacks, and we know the main causes. We don’t have perfect coding by crew yet, but we can show the log and the trend is improving.
Red flag
We don’t really track callbacks. It’s part of the business and our guys handle it when it comes up.
How Rejigg helps:Rejigg’s data room keeps your callback log, warranty summaries, and install quality process docs together for buyer diligence.
Who owns replacement sales and daily operations when you’re not the traffic cop?
Deal-critical
Owner Dependence

What buyers determine

Buyers are testing whether the business runs on roles or on you personally. They want to see who owns replacement quoting, financing setup, dispatch decisions, customer saves, and install quality control. If the owner is the only closer or the only person who can keep the schedule from blowing up, the buyer assumes the handoff will be shaky and prices that risk in.

How to prepare

  • Write down the day-to-day operating roles and assign each one to a named person
  • Document the service-to-replacement handoff, including who presents options and handles financing
  • Create a 90-day transition plan with specific responsibilities and a meeting cadence
  • Identify single points of failure (one dispatcher, one lead installer) and write a backup plan
Great answer
I don’t run dispatch day-to-day. Our office manager runs the board and our lead CSR (Customer Service Representative) owns call handling scripts and booking. Replacement is handled by two comfort advisors who quote standardized options in the field and run financing through our portal. I’ll stay on for 60 days post-close for vendor introductions, license continuity if needed, and weekly install quality reviews.
Good answer
I’m still involved in replacement on bigger jobs, but we have a comfort advisor taking more of that load and dispatch is handled by the office. I can commit to a structured transition period.
Red flag
I do the quoting, I manage dispatch, and I jump in wherever needed. The team will adjust once I’m gone.
How Rejigg helps:Rejigg’s direct messaging and scheduling make it easy to run transition discussions with buyers and document a 30/60/90-day handoff plan.
Is your lead flow dependent on one channel you don’t control?
Important
Demand Engine

What buyers determine

Buyers are looking for lead volatility and margin risk. If most booked calls come from one paid source, a home warranty program, or a single relationship, a buyer assumes the calendar can fall apart or margins can get squeezed fast. They also want proof your phones are answered and booked well, since that turns average leads into real revenue.

How to prepare

  • Pull 12–24 months of leads by source, including booked jobs and average ticket by source
  • Show peak season and shoulder season separately so the pattern is clear
  • Document call answering coverage and your booking process for nights and weekends
  • Explain partner channels (home warranty, builders, property managers) and typical margins
Great answer
Over the last 12 months, booked calls were 34% memberships and existing customers, 28% Google Business Profile and referrals, 22% paid search, and 16% property managers. No single channel is over a third. Here’s call tracking by source with booked rate and average ticket, plus how we staff phones after-hours so we don’t leak calls during heat waves.
Good answer
We know our biggest channels, and we can show call tracking for the last year. We haven’t fully broken out ticket size by source yet, but we can pull booked jobs and close rates.
Red flag
Most of our work comes from one partner, and we don't really track lead source. If that slows down, we’ll just spend more on ads.
How Rejigg helps:Rejigg’s buyer vetting and digital NDAs let you share lead-source and call-tracking proof with serious buyers while keeping sensitive channel details controlled.
Can dispatch handle peak season without overtime heroics and missed calls?
Important
Dispatch Capacity

What buyers determine

Buyers want to know how the shop performs during the first big heat wave after closing. They are listening for missed calls, slow response times, overtime creep, and whether install crews get pulled into emergencies all week. Dispatch is also a growth constraint, so strong processes and seasonal staffing plans usually raise confidence.

How to prepare

  • Summarize CSR and dispatcher staffing by season, including after-hours coverage
  • Track missed calls, time to first contact, and peak-month booking backlog for non-emergencies
  • Document zoning rules, maintenance blocks, and how you protect install crews
  • Show overtime as a share of payroll in peak months and explain the drivers
Great answer
In peak months, we run two CSRs and one dispatcher until 8pm, plus an answering service that books emergencies into our software. Last July we missed about 6% of inbound calls and our average call-back time was under 10 minutes during business hours. We don't pull install crews into service except for true no-cool emergencies.
Good answer
We staff up in summer, and we have basic after-hours coverage. We don’t track every metric perfectly, but we can show overtime levels and booking backlog during peak season.
Red flag
Peak season is always chaos. Everyone works late, and we do whatever it takes. We don’t really track missed calls or response time.
How Rejigg helps:Rejigg helps you organize dispatch staffing, schedules, and basic performance proof in the data room so buyers can diligence operations quickly.
Can you hire and retain techs without the owner’s personal network?
Important
Labor Depth

What buyers determine

Buyers are underwriting whether labor will cap growth and whether key people will stick around after closing. They look at technician tenure, on-call load, training ramp time, and whether recruiting comes from repeatable channels or just the owner’s contacts. If one lead installer or dispatcher holds everything together, buyers usually ask for a tighter transition plan.

How to prepare

  • List headcount by role and experience level, and summarize tenure
  • Document recruiting channels and the last five hires, including where they came from and how they worked out
  • Write down onboarding and training steps for the first 30–60 days
  • Explain on-call rotation, pay structure, and guardrails around spiffs and commissions
Great answer
We have 8 service techs, 2 install crews, and 3 helpers. Five techs have been here over three years, and our on-call rotation is one week every eight with comp time and a minimum pay guarantee. Most hires come from referrals plus one trade school relationship, and we use a 30-day ride-along checklist before someone runs solo calls.
Good answer
We can show the roster and turnover history. Recruiting is working, but it’s still dependent on a couple relationships and we’re building a more repeatable pipeline.
Red flag
I hire techs through people I know. If we need more, I’ll just ask around.
How Rejigg helps:Rejigg lets you share an org chart, onboarding checklists, and retention history in the data room so buyers can evaluate team stability with proof.
What equipment, vehicles, and inventory realities will surprise a buyer in the first 12 months?
Good to have
Fleet & Parts

What buyers determine

Buyers are estimating near-term cash needs after closing. A couple dead vans in July, a parts room full of old equipment lines, or uncontrolled truck stock can quietly chew up profit even if revenue holds. They want a straight answer on replacement timing, who owns what, and whether parts control prevents shrink and wasted drive time.

How to prepare

  • List each truck with age, mileage, ownership status, and expected replacement timing
  • Summarize fleet downtime and how you handle repairs during peak season
  • Document inventory controls, including who counts, how often, and how truck stock gets replenished
  • Identify dead stock and any emergency inventory that rarely turns
Great answer
We run 14 vehicles. Average mileage is 92k, and two vans likely need replacement within 12–18 months based on maintenance history. Trucks are company-owned except for one installer van that's financed. We do monthly cycle counts, restock trucks weekly against a standard list, and we already wrote off about $18k of dead stock from an old brand change.
Good answer
We have a fleet list and a good sense of what needs replacement soon. Inventory is generally controlled, but we’re still tightening up truck stock and dead parts.
Red flag
I'm not sure how old the trucks are, and we don't really track inventory. We just grab parts when we need them.
How Rejigg helps:Rejigg’s data room makes it simple to share a fleet schedule, inventory summary, and financed vehicle documents while controlling buyer access.

Straight from buyer evaluations

“The customers just kept renewing their maintenance plans year after year without anyone having to chase them. That kind of loyalty doesn't happen by accident — it tells you the service is genuinely good.”
Customer LoyaltyBuyer impressed by customer retention at a residential HVAC company
“I talked to the office manager and she had everything running — scheduling, dispatch, invoicing — without the owner being involved at all. That told me this business would keep humming after the handoff.”
Strong TeamBuyer seeing how well the team operates independently
“What got my attention was the mix. They weren't just doing installs or just doing repairs — they had steady work coming in from all directions, all year round. That's a business that doesn't live and die by the season.”
Year-Round RevenueBuyer reviewing the balance of revenue at an HVAC company
“Everything was tracked. Every job had a cost, every tech had numbers, and it all matched the books. You don't always see that, and when you do, it makes you want to move fast before someone else does.”
Clean BooksBuyer reviewing how well an HVAC company tracks its numbers
“Twenty-plus years in the same area, and the name still means something. People call them because their neighbor used them. That kind of reputation is worth more than any ad campaign.”
Local ReputationBuyer recognizing the value of a long-standing local HVAC brand

How buyers value this type of business

Where you land in that range depends on a few things: whether the business runs without you, how many customers come back automatically each year, and how clean your books are.

3x–8x
annual profit
Depending on size, team, and recurring revenue

What drives a premium

  • Customers who come back every year
    Maintenance agreements and repeat service customers give buyers confidence that revenue will keep flowing after the sale.
  • A team that runs without you
    If your techs, dispatcher, and office staff handle the day-to-day, buyers see a business they can step into — not a job they're buying.
  • Licensed techs on staff
    Having multiple licensed technicians means the business doesn't depend on one person to legally operate. That's a big deal to buyers.
  • Steady work across service, repair, and installs
    A mix of different revenue keeps the business busy year-round and makes buyers less worried about slow seasons.
