What LIZZI SRL does
LIZZI SRL is an Italian limited liability company headquartered in Senago (Milan), founded in 1980 by Randolfo Lizzi as a sole proprietorship and converted to a capital company in 2000. The firm specializes in the maintenance, repair, and installation of residential climate-control systems — condensing boilers, air-to-water heat pumps, hybrid boiler/heat-pump systems, solar thermal, photovoltaic, and air-conditioning units — operating as an Authorized Immergas Technical Assistance Center since 1990 under the Immergas Services Code (Decalogo dei Servizi). LIZZI reports a cumulative base of more than 64,000 residential customers served across the Milan and Monza Brianza provinces, supported by approximately 85 employees (one source) versus 34 in a firmographic snapshot, reflecting either seasonal staffing, sourcing inconsistency, or recent workforce changes.
The business operates a direct-to-consumer service model: customers reach the company by phone, WhatsApp, website forms, or walk-in, with emergency response guaranteed within 24 hours and 7-day availability during winter. Revenue is generated through professional-services fees for ordinary and extraordinary HVAC maintenance, new installations (with products sourced primarily from Immergas and partner brands such as MAXA, REHAU, EUROTHERM, HISENSE, ROBUR, and WAVIN), warranty validation and activation (free for Immergas), and sales of original spare parts. Pricing is quote-based and not publicly disclosed, with free warranty activation as a customer-acquisition mechanism. Online channels (a content-rich website, Facebook, Instagram, LinkedIn, WhatsApp Business, and a System Configurator tool) support lead generation, while on-site field service remains the primary fulfillment mode. The company remains family-controlled under Mauro Lizzi, with no disclosed external investment, M&A, or funding activity.

LIZZI SRL competitors and assessment
Company assessmentBroad incumbents
- Ariston Group: Milan-headquartered global manufacturer of boilers, heat pumps, and HVAC components with an extensive authorized service-partner network across Italy. Comparable to LIZZI at the brand/service-network level: Ariston operates the type of authorized-center ecosystem in which LIZZI participates, just at much greater scale.
- Daikin Italy: Italian subsidiary of the global HVAC leader, offering heat pumps, air conditioners, and hybrid systems with certified installer and service-partner networks. Comparable to LIZZI as a major HVAC OEM operating the same authorized-partner service model in Italy.
- Unical: Italian HVAC manufacturer of boilers, heat pumps, and solar thermal systems with its own authorized-service network across Italy. Comparable to LIZZI in being an Italy-focused residential HVAC brand that competes for the same authorized-service-partner economics.
- Vaillant Italia: Italian arm of the German heating manufacturer (Vaillant Group), offering condensing boilers, heat pumps, and climate-control systems with an authorized service-center network. Comparable to LIZZI as a competing OEM that competes for the same authorized-partner slot in Italian territories.
- Bosch Home Comfort Italia: Italian operations of Bosch's residential heating and hot-water division, selling boilers, heat pumps, and hybrid systems through an authorized installer/service-partner network. Comparable to LIZZI at the HVAC-brand × authorized-partner intersection, with significantly broader product and geographic scope.
- Baxi: European HVAC manufacturer of boilers, heat pumps, and hybrid systems with an Italian service-partner network. Comparable to LIZZI in product portfolio (condensing boilers, heat pumps, hybrids) and in the way it routes installation/maintenance through authorized local partners.
- Riello: Italian manufacturer of heating and climate-control products (boilers, burners, heat pumps) that maintains a national authorized-service-partner network. Comparable to LIZZI as an Italian HVAC brand with a parallel authorized-center go-to-market structure.
- Leroy Merlin Italia: Italian home-improvement retailer selling HVAC equipment (boilers, heat pumps, AC) with installation services across Italy. Comparable as a much larger incumbent offering overlapping residential HVAC sales + installation in the same geographies where LIZZI operates.
Direct peers
- ProntoPro: Italy-based professional services marketplace with a major HVAC/idraulico category, connecting homeowners to vetted local installers. Directly comparable to LIZZI in target customer (residential), offering (boiler/heat-pump installation and maintenance), and D2C acquisition motion.
- Idraulico.it: Italian online platform that matches residential customers with local HVAC/plumbing installers for installations, maintenance, and emergency repairs. Comparable to LIZZI as it sells the same residential HVAC service offering (boilers, heat pumps, AC) through direct-to-consumer demand in Italian territories.
