Onnit Heating and Cooling LLC

Onnit Heating and Cooling LLC serves Westland, Michigan as a residential HVAC contractor with a 4.9-star rating across 28 client reviews. The company handles heating and cooling system installations, repairs, and maintenance for homeowners throughout the western Detroit metropolitan area. Multiple reviewers specifically mention scheduling the company for both air conditioning and furnace service, indicating the business operates year-round to address seasonal equipment needs.

The company distinguishes itself through transparent pricing practices that customers repeatedly praise. Reviewers note receiving multiple repair estimates with options rather than facing pressure toward the most expensive solution. One customer specifically appreciated receiving two estimates the same day after an AC diagnostic, allowing them to choose the repair approach that fit their budget. This approach to presenting options rather than upselling appears consistently across customer feedback.

Customers describe specific scenarios where technician Durron addressed equipment problems other contractors had difficulty diagnosing. One homeowner reported their air conditioning had stopped cooling the house completely, and Durron discovered all the refrigerant had leaked out. After performing a leak check, he identified the leaking valve, provided multiple repair options, and completed the replacement so the system again cooled effectively. Another reviewer mentioned scheduling a furnace check before cold weather arrives, demonstrating the company's role in preparing homes for Michigan's seasonal temperature shifts.
