If you own an HVAC or mechanical contracting business in Portland, Maine and you are starting to think about the next chapter, Investera Holdings is worth a conversation. We are a Michigan family-operated buyer that acquires service companies and keeps operating them — not a broker chasing a listing, and not a passive fund looking to flip. We buy well-run trade businesses, install strong systems and a dedicated general manager so the company runs without the owner, and keep the technicians, the service agreements and the reputation working for years. Our portfolio companies, including Optimal Facility Services and CT Cleaners, show that we live in the operating details of service work rather than watching from a distance.
Why Portland owners are thinking about selling now
Few markets reward a strong HVAC and mechanical company like Portland does. Maine’s long, cold heating season makes climate control a year-round necessity, and the region is in the middle of a historic shift from oil to electric heat pumps, propelled hard by Efficiency Maine rebates and the state’s aggressive heat-pump adoption goals. That transition, layered on top of Portland’s dense stock of aging Victorian, brick and mill-era buildings in the West End, Old Port and Bayside, means service, retrofit and replacement demand that does not slow down. Add commercial refrigeration and mechanical work for the city’s booming restaurant and craft-brewery scene, and a good shop rarely runs out of backlog.
Warming summers are quietly changing the business too. Cooling that used to be a luxury in Greater Portland is now routine, expanding air-conditioning and mini-split installs and giving established contractors a second seasonal revenue stream to complement winter heating calls. The catch is people: skilled techs are scarce and hard to keep, and many shops depend entirely on an owner who still runs every estimate, dispatch and tricky service call. If that owner is you and you cannot imagine the business without you in the truck, that dependence is exactly the risk a buyer with real systems and management can take off your shoulders.
Who we buy in the Portland area
We are selective. We are looking for a mechanical business with real service revenue and a bench, not a one-person operation that disappears the day the founder stops answering the phone.
- Recurring service agreements or steady repeat and contract work
- Around $500K or more in annual revenue or SDE (close is fine)
- Licensed technicians and a lead who can run jobs without you
- A solid reputation across residential, commercial or institutional clients
- An owner ready for a clean handoff — or willing to stay on through a transition
If that describes your shop, it is worth a conversation now, even if you are still a season or two from making a decision. Good exits are planned, not rushed.
What makes selling to Investera different
No broker fees. We purchase directly from owners, so there is no listing commission taking a bite out of your proceeds and no broker inserted between us.
A confidential process. Your techs, your customers and your competitors learn nothing until you choose — we keep conversations private so service agreements and crews stay stable.
Creative deal structures. All-cash exit, phased transition, or terms tied to the service base you have built — we shape the deal around what you actually want.
Operators, not a fund. We are a family that runs service businesses and puts a general manager and systems in place so the shop thrives without the founder — not financial buyers looking for a quick resale.
How the process works
It begins with a single confidential call about your business, your service base and your goals. If there is mutual interest, we sign an NDA and you walk us through revenue, agreements and staffing at a high level. We then bring you a clear, honest offer, and if the terms fit we move into a focused due-diligence period and a clean close. You work directly with our family and the operators who will run the company — not a revolving door of associates who have never turned a wrench.
We will take care of what you built
After a purchase, our priority is to safeguard what makes your shop valuable: the service relationships, the licensed techs who know the territory, and the trust behind your name. We add a dedicated general manager and disciplined systems for dispatch, maintenance agreements and quality so the operation no longer hinges on the founder. Technicians keep working, customers keep their coverage through Maine winters and warming summers, and the business gains the depth to capture the heat-pump and commercial mechanical demand that keeps flowing through Greater Portland.

Frequently asked questions
How much is my HVAC business worth in Portland?
HVAC and mechanical companies generally sell for about 2.5x to 4x SDE (seller’s discretionary earnings), with recurring service agreements, technician retention and a strong reputation pushing toward the top of that range. It is a typical range, not a promise — a confidential look at your numbers is the only way to get a real figure.
Will my sale stay confidential?
Yes. We know an early leak can unsettle techs and customers alike. Everything runs under a mutual NDA, and nothing reaches your staff, clients or competitors until you say the timing is right.
Do you charge any broker fees?
No. We are the buyer, not a broker, so there are no listing commissions or middleman fees pulled from your proceeds. You deal directly with us.
Can I stay on after selling?
If you want to, yes. Some owners hand off and step away, others stay for a season to transition relationships and key accounts. We fit the plan to your preference.
What is the typical timeline?
When we both see a fit, a straightforward deal often runs from first conversation to close in about 60 to 90 days, depending on information flow and the structure you choose.
What areas around Portland do you buy in?
In addition to Portland, we consider HVAC and mechanical companies serving South Portland, Westbrook, Biddeford, Scarborough and nearby Cumberland County towns.
