About Allseason Air Conditioning

Founded in 2005, Allseason Air Conditioning has built a reputation in Sterling Heights, MI as a straight-shooting independent hvac contractor that doesn't push system replacements when a repair will do. The team is unusually rigorous about indoor air quality and ventilation work in addition to core heating and cooling, and is one of the few local shops that will quote both a repair and a replacement option on the same visit so homeowners can make an informed call. NATE-certified, state-licensed, EPA refrigerant-handling certified, and proudly insured.

Allseason Air Conditioning serves homeowners across Sterling Heights, MI and surrounding ZIP codes including 48310, 48312, 48313, 48314. Pricing is up-front and quoted in writing before any work begins, with no obligation if the estimate isn't right for your project.

Honest pricing, showed up on time, and explained exactly what was wrong before doing anything. Quote was 25% lower than two other shops we called.

Got us booked the same day and finished the job in a single visit. Cleaned up everything before they left — couldn't even tell they'd been here.
