Selling your HVAC business

01What buyers value in an HVAC business

Most HVAC businesses combine three kinds of work: planned preventive maintenance, reactive repairs and call-outs, and installation or replacement projects. Each has a different risk profile, and buyers will want to see how your revenue and margin split between them.

Planned maintenance tends to attract the most attention because it provides visibility and keeps engineers on customer sites, where reactive and project opportunities often come from. But a business does not need to be maintenance-led to be attractive — what matters is that the mix is understood, profitable and well managed.

Buyers rarely value an HVAC business on turnover alone. They want to understand which revenue recurs, how profitable it is and how reliably it is delivered.

02Maintenance agreements and service revenue

Expect to be asked for a schedule of your maintenance agreements, including:

• Sites covered and the equipment maintained — for example air handling units, chillers, heat pumps, boilers, split systems or refrigeration plant.
• Visit frequency, annual contract value and what is included or excluded.
• Renewal dates, notice periods and how long each customer has been with you.
• How reactive work and remedial quotations arise from maintenance visits, and how often they convert.
• Whether pricing has kept pace with labour and parts costs.

Contracts held through facilities management companies are common in this sector. Buyers will want to understand those relationships, how much of your work depends on them and how secure they are.

03Technical compliance and accreditations

HVAC work often involves regulated activities, and buyers will check that the business is properly set up to carry them out. Depending on your services, that may include, for example:

• F-Gas company certification and individual engineer qualifications for work on refrigeration, air conditioning and heat pump systems, together with refrigerant handling and leak-check records.
• Gas Safe registration for engineers carrying out work on gas appliances.
• Trade association membership, such as BESA, and any manufacturer approvals or service partner arrangements.

It is worth checking which certifications sit with the company and which depend on individuals, and how each would be affected by a change of ownership. Manufacturer partnerships in particular can have their own terms, so review them before a buyer asks.

04Engineers, site knowledge and owner dependence

Experienced HVAC engineers are hard to recruit, and much of the value of a mechanical services business sits in their knowledge of customers’ sites and equipment. Buyers will look at team stability, skills mix, training and how work is supervised.

They will also ask how dependent the business is on you. If you still price every job, manage key accounts and solve the hardest technical problems, a buyer will want to see how those responsibilities could be shared over time — for example through a service manager, an estimator or senior engineers with clear authority.

05Project work, contract risk and working capital

Installation and replacement projects can be profitable, but they bring risks that buyers examine carefully: fixed-price contracts, variations, retentions, defects liabilities and payment terms with main contractors.

Expect questions about work in progress, how projects are costed and tracked, any disputes or outstanding retentions, and how much working capital the business needs to fund project activity. Clear job costing and up-to-date project reporting make these conversations much easier.

06What due diligence is likely to cover

• Management accounts, adjusted earnings and the profitability of maintenance, reactive and project work.
• Maintenance agreement schedule, key customer and facilities management relationships.
• F-Gas, Gas Safe and other certification records, and refrigerant logs where relevant.
• Open projects, work in progress, retentions, warranties and any disputes.
• Health and safety documentation, insurance and claims history.
• Engineer contracts, qualifications, training and vehicle arrangements.
• Job management systems and how service records are kept.

07Preparing your HVAC business for sale

• Separate maintenance, reactive and project revenue and margin in your reporting.
• Build a clear, up-to-date maintenance agreement schedule.
• Check certifications, registrations and manufacturer agreements, and how each would be affected by a sale.
• Make sure F-Gas records and service documentation are complete and accessible.
• Tidy up open projects, retentions and any long-running disputes.
• Delegate pricing, customer relationships and technical sign-off where you can.

09Frequently asked questions

Our work is mostly projects rather than maintenance. Is the business still sellable?

Yes. Project-led businesses can be attractive, particularly where they have strong margins, repeat customers and good project controls. Buyers will look carefully at work in progress, contract risk and how consistent results have been over several years.

Will our F-Gas certification and Gas Safe registration carry over?

It depends on how the sale is structured and the rules of each scheme. In a share sale the company usually continues, although you may still need to notify the relevant body. In an asset sale the buyer may need its own registrations. Check with each scheme before starting a process.

Much of our work comes through facilities management companies. Will that concern buyers?

Buyers will want to understand those relationships, how long they have lasted and how much revenue depends on them. A spread of facilities management and direct customers, with a good track record, is usually viewed positively.

Do manufacturer partnerships transfer to a new owner?

Sometimes, but each manufacturer has its own terms. Review your agreements early and be ready to explain which approvals are linked to the company and which to individual engineers.

Do I need to be ready to sell before speaking to Phixr?

No. Many owners begin with a confidential conversation simply to understand their options and what a future transaction might involve.
