Janssen HVAC

Janssen HVAC has built a reputation in Mt Pleasant and the surrounding Charleston County area as a contractor that prioritizes honest recommendations over aggressive upselling. With 39 five-star reviews reflecting years of consistent service, the company is led by Lee, who brings hands-on expertise to every job site. Founded to serve residents of Mt Pleasant, Isle of Palms, and neighboring communities, the team handles both routine maintenance and complex system reconfigurations for homeowners throughout the region.

What distinguishes Janssen from other area contractors is their commitment to transparent pricing and technical transparency. Rather than recommending system replacements when repairs suffice, the team takes time to explain options and walk homeowners through each step of the diagnostic process. Reviewers consistently note that Lee and his technicians never push unnecessary services, instead offering practical solutions that save customers money. This customer-first approach has earned the company loyal, long-term clients who return for bi-annual service visits.

Homeowners recount specific scenarios that demonstrate Janssen's capabilities. Michael Seklecki needed his HVAC units relocated during a home remodel, a complex job requiring temporary hookups to maintain heating during foundation work. Lee provided the lowest bid among three quotes and completed the project successfully. During an arctic weekend, Lorna Weber's thermostat failed, and despite outside temperatures, Janssen sent a team that installed a temporary heating solution the same evening before returning the next day with a permanent replacement. Andre Berenzon has maintained a year-long relationship with the company, citing their honesty and reliability as qualities that earned his complete trust.
