Hollis Heating, Air Conditioning and Boilers

Hollis Heating, Air Conditioning and Boilers has earned a 4.9-star average across 10 customer reviews while serving Detroit and Grosse Pointe residents for over 25 years. This locally-rooted contractor handles residential and commercial projects, offering boiler installation and repair, furnace services, air conditioning repair and installation, water heater solutions, and commercial HVAC system work. Their service area spans the broader Detroit metro, making them a practical option for homeowners across multiple neighborhoods seeking reliable heating and cooling support.

What distinguishes Hollis Heating from competitors is their specialization in boiler systems, a heating technology that many area contractors have moved away from in favor of forced-air furnaces. The company partners with more than 25 quality brands, giving them flexibility to recommend equipment that fits each customer's budget and heating requirements. Their willingness to tackle complex boiler work, combined with commercial HVAC capabilities, positions them as a versatile option for property managers and homeowners alike who need an experienced contractor for older heating infrastructure.

Several reviewers highlight specific technicians who delivered exceptional service. Stephen responded to David Georgis's air conditioning issue within 30 minutes and had the system fully operational within an hour. During a Christmas Day emergency, Stephen not only addressed a burst pipe situation but also sourced a furnace part and restored heat the same day for Phil Allison. Zoe and Stephen together earned multiple recommendations from reviewers who praised their professionalism and friendly demeanor. The fast response times and personal attention from named technicians appear frequently across their feedback.
