Apollo

Apollo Heating & Cooling operates as a Carrier factory-authorized dealer based in Wentzville, Missouri, serving the Greater St. Louis and Greater St. Charles county regions. With a rating of 4.1 stars drawn from 34 customer reviews, the contractor maintains standard weekday hours from 7:30 AM to 5 PM with Saturday availability from 10 AM to 2 PM. The company provides 24-hour emergency response seven days a week, distinguishing itself among regional HVAC providers through its manufacturer-recognized status that fewer than one percent of U.S. contractors achieve.

The contractor's differentiation stems from its Carrier brand partnership, offering the full product spectrum including air conditioners, heat pumps, gas furnaces, geothermal systems, boilers, and advanced indoor air quality solutions such as ultraviolet lights and air cleaners. Specializing in sheet metal fabrication and air duct sealing, Apollo also conducts energy audits to help homeowners optimize system efficiency. The company promotes service agreements designed to prevent unexpected breakdowns and offers financing options for new installations and upgrades.

Long-term customer relationships define the company's reputation, with one reviewer noting continuous patronage spanning 23.5 years and successful full-system replacements completed within a single day. Multiple reviewers highlight specific technicians who exceed expectations: Sheri Guinn praised the team's patience throughout a new system installation decision process, while Lindsay Chott described an emergency same-day furnace repair during extreme winter conditions that restored heat within hours. Richard Lusa's review detailed a time-sensitive rental property intervention for a tenant with a special-needs child, demonstrating willingness to accommodate vulnerable household situations.
