Environmental Comfort Inc

Environmental Comfort Inc operates as a residential HVAC contractor in Streamwood, Illinois, serving the greater DuPage County corridor including Wheaton, Glen Ellyn, and Bartlett. Owner Mark provides furnace, boiler, air conditioning, and water heater services across these communities. The business holds a solid 3.9-star rating derived from 10 verified homeowner reviews, with most customers highlighting consistent service spanning anywhere from 10 to nearly 30 years. The company maintains standard weekday hours from 9 AM to 5 PM with Saturday availability until 1 PM, closed Sundays.

What distinguishes this contractor comes through in how Mark handles each situation rather than manufacturer partnerships or specialty certifications. Several reviewers specifically note his willingness to make exceptions during emergencies, showing up on holidays or working late to restore heat when systems fail. Fair and transparent pricing appears repeatedly across the positive reviews, with multiple customers contrasting his approach against larger companies that quote unnecessary upgrades. The business handles both conventional forced-air furnaces and boiler systems, plus the specialty water storage tank installations mentioned by a_long-term client.

Customer scenarios reveal Mark's dedication to keeping families comfortable regardless of timing. One reviewer recounted calling on Christmas Eve during sub-zero weather when the furnace failed completely; Mark sourced replacement parts rapidly and completed the installation the same evening to prevent pipe damage from freezing. Another long-term client has used Environmental Comfort for over 15 years across multiple rental properties, trusting the team with boiler and furnace maintenance when others couldn't solve persistent heating issues.
