Mark IV Heating, Cooling & Refrigeration operates as part of the Brewer Heating & Cooling family, serving residential and commercial clients across Greenwood, Center Grove, Southport, and surrounding Johnson County neighborhoods in the Indianapolis metro area. With roots extending over 25 years in Central Indiana, the company maintains a 4.8-star rating drawn from 251 client reviews, reflecting consistent service quality in heating and cooling installations, repairs, and preventive maintenance for homes and facilities throughout the region.
This contractor differentiates itself through Trane brand partnerships, enabling access to commercial-grade heating and cooling systems including furnaces, heat pumps, geothermal installations, and ductless mini-split configurations. Their service menu encompasses indoor air quality solutions, zoned HVAC systems, and commercial refrigeration, capabilities that address both typical residential needs and more specialized building requirements common throughout Johnson County's mix of older homes and newer developments near Center Grove.
Client reviews cite specific technicians who delivered beyond-standard service: Tim arriving within 48 hours to diagnose an air conditioning issue and personally following up through a weekend, Jason completing a same-day repair call for a struggling homeowner and honestly explaining which future repairs could wait, and an installation crew at Immanuel United Church of Christ working extended hours to replace two rooftop units before a sub-zero cold spell arrived. These scenarios illustrate the contractor's willingness to prioritize emergency scheduling and transparent communication even when parts availability creates delays.
