About Atlantis Heating
Atlantis Heating is a Modesto-based HVAC contractor with a 3.1-star average across 17 client reviews. The company operates Monday through Friday from 8 AM to 5 PM and offers Saturday appointments between 9 AM and 4 PM, with Sundays reserved. Customers in Stanislaus County have engaged this team for furnace replacements and heating system diagnostics. Review records show work completed for both individual homeowners and clients with home warranty coverage.
The website for Atlantis Heating displays minimal public-facing content, making specific brand partnerships or specialty certifications difficult to confirm from online sources alone. Customer reviews reference furnace replacements and standard heating repairs, but the contractor has not publicly listed equipment brands, warranties, or specialty service categories on their site. Homeowners seeking particular equipment brands or specialized systems should confirm availability directly with the company.
Reviewer Sophie Hawkins described a furnace replacement handled by Constantine and a colleague, completed in a single day with thorough explanations of the new system. In contrast, reviewer Mat Pinasco reported a heater diagnostic that resulted in a recommendation for full system replacement, while a subsequent inspection by a different company identified a failed fuse as the actual issue. Reviewer Tim Gilliam detailed communication delays spanning weeks after an initial no-show, with eventual owner contact occurring on a weekend. These accounts suggest that response times and diagnostic accuracy vary across service calls.
What Customers Say
Of 17 reviews, 2 award 5 stars citing Constantine as professional and noting same-day project completion, while 2 award 1 star reporting diagnostic errors or no-shows. Positive reviews name specific technicians; negative reviews focus on home warranty coordination failures and misdiagnosis.
