Full Editorial Writeup

This is a 41-year-old industrial refrigeration contractor that designs, installs, services, and controls large-scale refrigeration systems. Its core work is in ammonia and CO2 industrial systems, cold storage warehouse infrastructure, and refrigeration for food processing and packing facilities. The business carries a multigenerational operating history and runs with roughly 54 to 75 employees serving commercial and industrial customers that need deep technical expertise.

The company reports approximately $35M in annual revenue and $12.25M in EBITDA, which implies the claimed 30% to 40% operating margins are at the extreme high end for a contracting business. That margin profile is the single most important thing to verify, because it is far above typical mechanical/refrigeration contractor economics and is what the $20M asking price (1.63x EBITDA) is built on. If the margins hold, this is a cheap multiple for a specialized, mission-critical industrial services platform with recurring maintenance relationships.

The seller frames this as an off-market platform for a strategic industrial services acquirer, refrigeration roll-up, or PE group, with the owner willing to stay on to support continuity and national expansion. The niche positioning (ammonia/CO2 industrial refrigeration with limited direct competition) and installed base of service contracts are the real assets here. The combination of regulatory-heavy refrigerant work and long customer relationships creates genuine switching costs.

Why we like it

Earnings quality looks strong on paper: $12.25M EBITDA on $35M revenue at a stated 30% to 40% operating margin. That is rich for a contracting business, so if it survives diligence it is exceptional, and even at half those margins the 1.63x multiple is attractive. The service and maintenance relationships add a recurring annuity layer on top of lumpy project revenue.
The moat is technical and regulatory. Industrial ammonia and CO2 refrigeration is specialized, safety-sensitive work that requires certified technicians and deep design expertise, which the seller says limits direct competition in its niche. A 41-year operating history and multigenerational track record give it credibility that newer entrants cannot buy quickly.
Market tailwinds are real and durable. Cold storage demand, food processing capacity, and refrigerant transitions (away from older synthetic refrigerants toward natural ammonia and CO2 systems) keep this work essential and growing. Temperature-controlled infrastructure is non-discretionary for the food supply chain regardless of the economy.
The revenue is largely recession-resistant because food facilities and cold storage must stay cold or product is lost. Maintenance contracts and emergency service generate repeat demand from the same installed base, so the business is not fully dependent on winning new installation projects each year.
Operator advantage: the seller will stay on post-close, which de-risks the transfer of technical knowledge, key customer and vendor relationships, and the refrigeration licensing that this trade depends on. For a strategic acquirer, this is a ready-made platform for geographic and national expansion.

How to improve it

Normalize and re-baseline the financials in the first 90 days to confirm the true recurring EBITDA. Separate project/installation margin from service/maintenance margin, strip out any owner addbacks, and understand revenue recognition on long-cycle installs so you are not buying a single big-project year dressed up as run-rate.
Formalize and grow the service and maintenance contract base into contracted, auto-renewing agreements. Converting ad hoc service work into scheduled preventive maintenance plans raises the recurring revenue floor, smooths the project lumpiness, and directly increases enterprise value at exit.
Build out a second-tier leadership and project management bench so the business is not dependent on the owner or a few senior technicians. This is critical given the owner-reliant history and the technical nature of the trade, and it protects against key-person risk before the owner fully exits.
Launch a structured technician recruiting, training, and certification pipeline. With only 54 to 75 employees in a trade constrained by certified labor, capacity (not demand) is likely the growth bottleneck, so an apprenticeship and retention program unlocks additional installation and service revenue.
Pursue the stated geographic expansion deliberately by targeting adjacent metros with heavy cold storage and food processing density. Follow existing national or multi-site customers into new regions rather than expanding blindly, using current accounts as the beachhead.
Implement job-costing and project management software to tighten bid accuracy and margin control. On large industrial installs, small estimating errors destroy margin, so better data on labor, materials, and change orders protects the exact margins that justify this valuation.
Capitalize on the refrigerant transition trend by positioning explicitly as an ammonia and CO2 retrofit and compliance specialist. Regulatory change forces facility upgrades, which is a durable pipeline of high-margin design-build and service work you can actively market into.

Diligence notes

The 30% to 40% operating margin claim is the headline risk and must be verified first. Industrial mechanical contractors rarely sustain margins this high, so demand three to five years of tax returns and audited or reviewed financials to confirm the $12.25M EBITDA is real, recurring, and not inflated by one large project or aggressive addbacks.
Scrutinize revenue concentration and backlog. Determine what share of the $35M comes from the top few customers and from one-time installs versus recurring service, and review signed backlog and contract terms, since losing one anchor cold storage client could swing the entire margin story.
Confirm licensing, refrigerant handling permits, and safety/environmental compliance. Ammonia systems carry serious OSHA PSM and EPA RMP obligations, so review inspection history, any incidents, insurance claims, and whether required licenses transfer with the sale or depend on the departing owner.
Pin down the owner's actual day-to-day role and the depth of the management team. The listing stresses owner involvement and national expansion, which suggests heavy key-person dependence, so quantify what the owner personally controls (sales, bidding, technical sign-off) and the real transition plan and timeline.
Verify workforce stability given the 54 to 75 employee range and the certified-labor constraint. Review tenure, turnover, wage rates, union status, and the technician certification pipeline, because this business lives or dies on retaining skilled refrigeration techs who are hard to replace.
Clarify what assets and real estate are and are not included at the $20M price. The listing does not mention owned facilities, vehicles, or shop equipment, so confirm whether the operating footprint is leased or owner-held and whether any related-party rent or asset arrangements affect the true cost of ownership.
