- Code reference
- Exemptions and permit triggers align with administrative sections (e.g., analogous to IBC/IRC Section 105 or city-specific Admin provisions such as those referenced in policy documents like ADMIN 131/138).Section 105
- Code reference
- Demolition has a specific reference (Denver Commercial Building Code Section 130.3 for exempted work).Section 130.3
- There is a tiered schedule (e.g., $1–$500

What HVAC work covers in the Denver metro
HVAC projects in the Denver metro include furnace and air-conditioner service, heat-pump and packaged-unit replacement, duct repairs, thermostat upgrades, and ventilation changes tied to remodels. Commercial buildings may also need rooftop units, zoning, and coordination with roofing or structural openings. A municipally licensed Denver general contractor coordinates the overall project and the licensed specialty trades required for mechanical and related electrical work. Scope should state whether the visit is repair, replacement, or a remodel that changes equipment location or duct routes.
text
Front Range climate and equipment choices
Denver winters and high summer temperatures put real load on heating and cooling equipment. Altitude, wide daily temperature swings, and wildfire-season air quality can influence filter strategy and outdoor-unit placement. Equipment selection should match the building's size, insulation, duct condition, and fuel or electrical service available on site. Replacement projects benefit from a load-aware assessment rather than one-for-one equipment swaps that ignore duct leakage or undersized returns. Cost is project-specific and depends on equipment type, access, duct work, and electrical or gas changes.
text
Remodel and commercial coordination
Kitchen, bathroom, and addition projects often change supply and return needs. Closing or opening rooms without adjusting airflow can create comfort problems. Commercial replacements commonly involve roof curbs, structural support, crane or lift access, and sequencing with roofing patches. A clear plan names equipment locations, thermostat zones, fresh-air requirements, and who will handle gas, electrical, and roof penetrations.
text
Permits and who coordinates the work
Many furnace, condenser, and duct alterations require mechanical permits and inspections through the local city or county. Related electrical or gas work is handled by the specialty trades qualified for that scope. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades for HVAC packages. Permit responsibility and inspection sequencing should be stated in the project plan.
FAQ
Common questions
Repair or replace — how do you decide?
Repair is often practical for localized failures on equipment that is otherwise sound. Replacement is more common when the system is near end of life, parts are scarce, or comfort and efficiency goals cannot be met with the existing unit and ducts. An on-site assessment should drive that choice.
Who handles the HVAC permits and licensing?
A municipally licensed Denver general contractor coordinates the project and the licensed specialty trades required for the work. Local city or county building departments issue mechanical and related permits. Colorado has no statewide general contractor license.
Do heat pumps work in Denver winters?
Cold-climate heat pumps can be appropriate for many Denver-metro homes when sized and installed for local design temperatures, often with a planned backup heat strategy. Suitability depends on the building envelope, electrical service, and comfort expectations.
How is commercial HVAC different from residential work?
Commercial projects more often involve rooftop equipment, larger duct systems, tighter sequencing around occupancy, and coordination with roofing and structural openings. Access for lifts or cranes can dominate the schedule.
What information helps define an accurate HVAC scope?
Equipment type and age if known, symptoms or comfort complaints, fuel source, recent utility bills if available, remodel drawings, and photos of the furnace closet, attic, or rooftop unit. Note the city or county for permitting.
