About Keystone Heating and Cooling
Keystone Heating and Cooling holds a 5-star rating from a single verified review in Keystone Heights, Florida. The contractor maintains 24-hour daily availability, ensuring homeowners across the Keystone Heights and Melrose areas can reach real support whenever equipment fails. This single-review standing reflects a recent customer engagement in mid-2026, with the business serving residential clients throughout Clay County and surrounding communities.
The review highlights a contractor who answers calls with immediate commitment rather than automated menus. A technician named Matt arrived within 45 minutes of the initial call during extreme summer heat, diagnosed a duct leak pulling hot attic air into the living space, and completed the repair without proposing additional services or price increases. The business operates without the upselling approach common among area competitors, focusing instead on accurate diagnostics and direct resolution.
A reviewer recounted calling multiple HVAC companies during a 95-degree afternoon with no response before reaching Keystone Heating and Cooling. The technician climbed into a Florida attic during peak summer temperatures to access the faulty ductwork, resolved the issue, and confirmed cooling restoration before departing. The reviewer specifically recommends contacting Matt for any homeowner facing AC failure in the Keystone Heights or Melrose area.
What Customers Say
