How to Buy a Home Service Business: A Contractor's Acquisition Guide

Why are contractors buying existing home service businesses instead of starting fresh?

Acquiring an existing business gives you something a startup cannot - a phone that already rings. You inherit technicians, trucks, customer relationships, and a Google Business Profile with reviews. Starting from zero means spending $60.50 per lead on Google LSAs (up 20% from 2023, per 99 Calls data) before a single dollar comes back in.

That math changes fast when you buy a business with 200 existing customers and a maintenance agreement book. If you want to understand how a recurring revenue base affects what a business is worth, read through how to grow an HVAC business with service agreements before you start valuing any deal.

What does a home service business actually sell for?

BizBuySell's 2025 valuation report put the median sale price of service businesses at nearly $400,000, up 13% year-over-year and 32% over five years. Earnings multiples on seller's discretionary earnings (SDE) range from 2x to 3x, with a cross-industry average of 2.49x SDE. Revenue multiples run 0.4x to 1.2x, averaging 0.64x.

For HVAC specifically, First Page Sage's 2025 report tracked EBITDA multiples averaging 8.5x for midsize companies - and that number has held steady even through interest rate increases. Small shops with one or two trucks still trade at 3x to 5x EBITDA, which is where independent buyers have a real edge before the roll-up funds find them.

How do you find a home service business to buy?

BizBuySell, BizQuest, and industry-specific brokers are the obvious starting points. But the best deals we have seen across dozens of contractor accounts came from direct outreach - calling an owner who has been running the same HVAC company for 22 years and asking if they have ever thought about retiring.

Owner @Gundwolf, who acquired a $4M HVAC business at age 24, found his deal through a personal connection - his friend's father owned it. The process took 10 months from first conversation to close, and a $300,000 inventory discrepancy surfaced during due diligence. His takeaway: do not attempt this without someone trusted who knows the trade technically.

Age and unconventional background will make brokers dismiss you, so go direct whenever possible. Knowing how to position yourself as a serious buyer also means understanding how to sell an HVAC company from the seller's perspective - it helps you speak their language.

What financing options do contractors use to buy a business?

The SBA 7(a) loan is the workhorse here. Maximum loan amount is $5 million, and the average acquisition loan through Live Oak Bank and similar SBA lenders runs approximately $1.3 million. Down payment requirements typically run 10% for SBA-financed ownership changes, meaning a $1.3M deal could require as little as $130,000 out of pocket.

For a deeper look at what financing options are actually available to contractor-buyers, how to get contractor financing lays out the landscape including equipment loans, seller notes, and SBA structures side by side.

Seller financing is your second tool. Many owners will carry a note for 10% to 30% of the purchase price, especially if they want to stay involved in the transition. That note also aligns their incentives - they want you to succeed.

The Owned and Operated founder financed his Nashville acquisition of a small HVAC company called Rapid Response entirely through an SBA loan and closed in 40 to 45 days from first contact. His lesson was clear: getting your foot in the door matters more than squeezing the last dollar out of the purchase price.

What should you look at during due diligence?

Start with three years of tax returns, not the profit and loss summary the broker emails you. Many home service businesses run personal expenses through the company - the owner's truck, phone, and health insurance all get added back in SDE calculations, but you need to verify every add-back yourself.

Check the customer concentration risk. If 40% of revenue comes from two commercial clients, that is not a stable business - that is a business one phone call away from a crisis. Understanding how to win commercial contracts also helps you evaluate whether those accounts are truly sticky or just relationship-dependent.

Review the technician roster carefully. In skilled trades, the business often walks out the door with key employees if the transition is mishandled. Make a plan to retain top performers before you close, not after.

Aaron Rice, who co-founded a plumbing and sewer business that sold to PE-backed Redwood Services in 2022, had 18 employees and roughly $3M in annual revenue at the time of sale. Redwood merged his company with a larger Tucson HVAC operation called Rite Way, and that combined entity grew from $30M to $70M in revenue under PE ownership. The employees and systems Rice had built were a major part of what made that growth possible.

Ask about the lead generation setup on day one. A business paying $105 per HVAC lead through shared lead platforms when it could be running Google LSAs at $60.50 average has a fixable problem. But if the entire customer pipeline runs through one aging owner's personal relationships, you are buying a job, not a business.

What makes a home service business worth paying a premium for?

Four things raise your ceiling on what a business is worth: a maintenance agreement book, strong Google reviews, owned equipment, and a manager who is not the owner. How to create a maintenance agreement program details exactly what a recurring revenue base looks like operationally - and why buyers pay more for it.

In the HVAC sector, the customer lifetime value math is compelling. Residential HVAC systems need replacement every 12 years on average at roughly $12,000 per unit, which Acquira calculates works out to over $1,000 in annual per-customer value. A business with 500 maintained customers is not just a revenue stream - it is a predictable asset.

Wrench Group, backed by Ken Langone, built the most extreme version of this logic. They looked at more than 3,000 companies over five years and bought 450 that fit their exact criteria - a 15% acceptance rate. Their first acquisition was a 3-truck HVAC company in Dallas doing $2M annually, purchased for $1.5M, which created $7.86M in equity within 12 months.

The full platform eventually exited at $14 billion. They bought individual companies at 3x to 5x EBITDA and sold the combined platform at 14x. That spread is the entire reason PE firms have gone from 8% of HVAC deals in 2023 to 50.6% in the first half of 2025.

What operational changes should you make right after closing?

The first 90 days determine whether your technicians stay or start sending resumes. Keep compensation structures intact, communicate the transition plan directly and early, and do not rebrand immediately if the local name has equity. If you are stepping into an HVAC operation, how to train HVAC technicians is worth running through before you touch any internal processes.

Fix the marketing infrastructure before you scale. Costs for home service advertising rose for 69% of businesses in 2025, according to LocaliQ's analysis of search advertising benchmarks across thousands of campaigns - roughly double the rate of increase seen in other industries. You need tracking on every lead source from day one, not month three.

Home service KPIs to track covers the specific metrics - cost per lead, close rate, revenue per technician, and customer acquisition cost - that determine whether your new business is actually profitable or just busy.

Set up your upsell and cross-sell systems in the first 30 days. A plumbing business doing $1M in revenue can generate $100,000 to $350,000 in profit depending on operational efficiency. Adding a second trade or service line is one of the fastest ways to move that margin needle, and how to add a second trade walks through the operational and licensing considerations without sugarcoating the staffing complexity.

Document everything the outgoing owner does from memory. Supplier relationships, callback policies, the way they price jobs, the customers they always give a break to - none of that is in any CRM. Shadow the owner for at least 30 days if your deal structure allows it.

Tracking your numbers from day one also means knowing your profit targets by trade. Contractor profit margins by trade gives you a benchmark so you know whether the business you bought is performing at, above, or below industry norms within your first quarter of ownership.
