Repair & diagnostics
The owner diagnoses your system personally and explains the findings, root cause and the practical options — repair or replace.
Equipment sourcing
We can source a broad range of residential equipment rather than pushing one manufacturer, so the equipment fits the home and the budget.
Assessment before pricing
We don't publish flat replacement prices. Every home is different, so we evaluate the existing equipment, ductwork and airflow, electrical or gas requirements, access, layout and your goals before pricing replacement or retrofit work. Projects that need substantial measurement, calculations, layout and system design may carry a paid design or assessment fee; if Dreadnought performs the installation, eligible design fees may be credited toward the project, subject to the proposal.
Permitting handled as required for the project. When electrical or other trades are needed, we use trusted licensed, bonded and insured subcontractors. Financing is not currently offered.
