Claim This BusinessAbout Prime Season
Prime Season is a full-service HVAC contractor based in Vernon Hills, Illinois, delivering heating, cooling, and plumbing solutions to homeowners and businesses across the northern suburban corridor. The company maintains round-the-clock availability seven days a week, handling everything from emergency furnace failures to scheduled AC installations. With a perfect 5-star rating derived from 22 verified client reviews, Prime Season has established a reputation for transparent communication and methodical diagnostics, guiding customers through equipment selections without applying high-pressure sales tactics.
What distinguishes Prime Season from neighboring contractors is their focus on whole-house indoor air quality, offering Aeroseal duct sealing technology that actively reduces energy loss through hidden leaks in ductwork, a service rarely advertised by competitors in the Lake County market. Their technicians hold certifications for heat pump installations and can advise on whether a traditional furnace paired with central air or a ductless mini-split system better matches a home's insulation profile and budget. For homes with persistent humidity issues or radon concerns, Prime Season provides dedicated mitigation packages including post-installation testing to verify contaminant levels stay within safe ranges, often completing these projects in a single service call.
Customer narratives shared through recent reviews point to Mark and his crew managing several notable scenarios: one homeowner in late December faced a complete furnace shutdown during subzero temperatures, and Prime Season facilitated a same-day replacement including permit coordination while working into the evening. Another client referenced adding an AprilAire whole-house humidifier alongside a full heating system upgrade, appreciating the unified approach rather than juggling multiple subcontractors. Reviewers consistently note the crews kept workspaces clean, arrived when promised, and explained each line item before proceeding.
What Customers Say
Eight reviews collectively award five stars, with multiple clients specifically praising Mark for honest assessments and Vlad Eydelman highlighting the team's willingness to work late during winter emergencies. Three reviewers mention pricing as fair or competitive, while none cite unexpected add-ons. Customers describe service as professional and efficient, contrasting with previous contractors who either missed underlying issues or proposed unnecessary replacements.
