Horizon Residential

What Horizon Residential does

Horizon Residential, operating as Horizon Homes, is a family-owned home energy efficiency contractor headquartered in Westbrook, Maine, serving Greater Portland and Southern Maine since its founding in March 2006. The company delivers a whole-home energy improvement offering that combines building-envelope work with HVAC upgrades, including Mitsubishi cold-climate heat pump installation, blown-in cellulose and rigid foam insulation, professional air sealing with blower door diagnostic testing, and high-efficiency condensing boiler installation. Free, no-obligation in-home energy assessments performed by certified advisors (including BPI-certified crews) generate leads and produce prioritized improvement plans with explicit pricing and Efficiency Maine rebate breakdowns. The company is a certified Mitsubishi Diamond Contractor and has held Efficiency Maine Top-Rated Vendor status for over 10 years, with 2,500+ homes improved since inception.

The business model is direct-to-consumer and project-based, with no intermediaries, subcontractors, or recurring contracts. Revenue is generated primarily from one-time installation projects ranging from $1,500 (air sealing only) to $25,000 (whole-home weatherization), with mid-tier bundles and heat pump systems in between. Horizon deducts Efficiency Maine rebates (up to $18,100 per household) directly from customer invoices and offers financing through Efficiency Maine Green Bank and NEIF Energy Plus, lowering customer friction. Customer acquisition combines paid digital marketing (Google Ads, Meta, Microsoft Advertising) with SEO-led content marketing, email, and referrals, all feeding the free-assessment funnel. The company operates with a small five-person team including a Field Manager (Luke), Office Manager/Project Coordinator (Nate), Sales Manager/Energy Advisor (Cody), and HVAC Service Manager (Mike), and is family-owned with no external investors, subsidiaries, or holding entities disclosed.

Direct peers

• ReVision Energy: Maine-based residential clean energy installer offering solar, heat pumps, and battery storage with a similar whole-home electrification focus. Highly comparable given overlapping service territory, customer base (Maine homeowners), and Mitsubishi product alignment.
• Sealed: New York-based home energy retrofit company funding and executing insulation, air sealing, and electrification projects with a savings-based pricing model. Comparable on whole-home weatherization focus and rebate-driven go-to-market.
• HomeWorks Energy: Northeast U.S. home energy retrofit company delivering insulation, air sealing, and heat pump installation with utility-program rebate expertise. Comparable on integrated envelope-and-HVAC model and mastery of state-administered incentives.
• Dr. Energy Saver (USA Insulation): National home energy retrofit franchise specializing in insulation, air sealing, and weatherization services. Comparable on whole-home energy diagnostics and insulation-led retrofits, though it operates through a franchise model rather than a single regional owner-operator.

Broad incumbents

• PosiGen: National residential energy efficiency and solar provider targeting LMI homeowners with bundled weatherization and electrification upgrades. Comparable on combining energy efficiency retrofits with financing, but operates at much larger scale with a national sales operation.
• BlocPower: National building decarbonization platform performing energy retrofits, electrification, and heat pump deployments for residential and small commercial customers. Comparable on whole-home energy efficiency scope, but operates at broader scale with a tech-driven software offering.

Others

• Mitsubishi Electric (Diamond Contractor Program): Manufacturer of cold-climate heat pumps whose Diamond Contractor certification Horizon currently holds. Included as a key technology partner — not a competitor — whose tier and warranty structure shapes Horizon's competitive positioning in the Maine heat pump market.
