Your Comfort is Our Priority!

Emergency Service




Climate Masters and USA HERS are members of a building performance team that takes a comprehensive systems approach to the diagnostic testing, analysis, and recommendations to improve the comfort level and indoor air quality in primary single family and multi–family buildings. This team takes a building science approach to evaluate problem areas, identify viable solutions, establish priorities, cost estimates, and implement the changes. Our philosophy is that a "one–stop–shop" approach is necessary for the owner to get the best value with a predictable outcome for their investment. We have the capability to model performance and conduct "what if" analysis to determine the most effective approach that yields the highest performance.

Climate Masters has complete fabrication and design shop with system test evaluation equipment. He has served on the Board of Directors of the St. Johns Builders Council for a number of years. Several of his numerous awards include; Carrier Florida Leadership Award, Habitat for Humanity Support Award, Navy League Military Support Award and Bryant Leadership Award. Mr. Schuler advocates support his staff and provides opportunities to maintain their expertise with new technologies. Prior to establishing Climate Masters he worked as a Master Mechanic for several large Mechanical Engineering firms of Jacksonville. His primary job included troubleshooting and maintenance of large scale industrial HVAC and mechanical systems at Naval Air Station Jacksonville.

Mr. Schuler has been working to transition Climate Masters into a complete building and home performance contractor. He’s very knowledgeable of the interactions of the HVAC systems with the building envelope performance. Frequently Climate Masters is called on to handle difficult comfort problems and to design and install systems for large custom homes and commercial facilities.

Henry DeWerth COO – USA HERS

  • FL Licensed Builder RB0067221
  • FL Licensed Home Inspector HI6371
  • FL Certified Energy Rater FL #692
  • NBI Air Balancing Certification 1011407
  • Energy Star New Home Verification Partner
  • EPA Indoor AirPlus Verifier

Background: Mr. DeWorth has dedicated the majority of his time in the past 14 years to the practical implementation of building science principles in the design, construction and remediation of problem or "sick" buildings. He has personally designed and built a number of Energy Star certified homes that have measurable energy efficiency levels and indoor air quality. He has also assisted approximately 50 Energy Star Builder Partners by providing training, end–to–end inspections, testing, and certifications of their Energy Star homes. He received the Energy Star for Homes Leadership in Housing Award in 2009 and 2010. Fallout from these earlier efforts lead to the establishing a building performance team approach spearheaded by Climate Masters, an Energy Star credentialed HVAC contractor.

Prior to getting into the construction business he held several technical and engineering positions with Oceanometrics, General Physics, and TRACOR. He served as the Director and Principal Analyst managing a team of 25 specialty engineers and technical staff in support of the U.S. Navy’s Anti–Submarine Warfare (ASW) and Acoustic Intelligence programs. This team was also charged with Research and Development Test and Evaluation (RDT&E) and rapid implementation of systems to support Fleet short fused operations. As the CEO at Oceanometrics he provided operational analysis and engineering support with Raytheon E–systems for the capabilities upgrade for the Australian and New Zealand RAF P–3C aircraft systems. He published numerous classifed analysis studies related to the radiated noise characteristics of Soviet built submarines. In these positions the understanding of the physics of sound pressure levels and how to measure them was critical to developing a system to exploit vulnerabilities. Some of these same mechanisms are related to understanding how a buiding "works" as a system.
