On licensing, the site states only that the company is "fully licensed to provide HVAC services in the Denver Metro area" and that technicians are "fully licensed, insured, and professionally trained." No Colorado state or municipal contractor licence number, registration number or insurance certificate is published on any page, so a licence number cannot be given out and must be requested from the office at 303-645-4889.
Years in business are stated inconsistently on the site: the home and about pages say "serving Colorado for over 18+ years," while auto-generated FAQ text elsewhere says "over 25 years" and "several years." No founding year for the business is published. On warranties, the services FAQ says a warranty is offered on installations and repairs "typically ranging from one to ten years, depending on the specific service and equipment used"; no warranty document or definite term is published, so warranty terms must be confirmed with the company.
