Right-size equipment selection
We base sizing on the home and your comfort goals, then match the furnace to the duct system so airflow stays in spec. This is the difference between steady comfort and a furnace that constantly cycles.

When it's time for a new furnace in Aurora
If you searched furnace replacement aurora co, you're probably dealing with one of two situations: your furnace stopped working at the worst time, or it still runs but you don't trust it anymore. In either case, replacement should not be a rushed swap. The furnace has to be sized correctly for the home, set up for safe combustion and venting, and installed to pass inspection.
Aurora's winters can turn quickly, so we focus on getting you back to dependable heat without cutting corners. That means checking the existing duct system and return air, confirming gas and venting compatibility, and making sure clearances, drainage for high-efficiency units, and electrical are right before we start. A new furnace that is oversized, poorly vented, or mismatched to the ductwork can be noisy, short-cycle, and wear out early.

What a proper furnace replacement includes
✓
Safe removal and disposal
Old equipment is disconnected, removed, and hauled out carefully. We protect floors and tight stairwells and keep the work area clean from start to finish.
✓
Code-compliant gas, venting, and electrical
We verify gas shutoff, sediment trap where required, venting material and slope, condensate routing for high-efficiency furnaces, and the furnace electrical disconnect and controls.
✓
Thermostat and control setup
We confirm staging, blower settings, and thermostat configuration so the system runs the way it was designed to run, including basic comfort balancing.
✓
Start-up testing and documentation
A replacement is not finished until it is tested. We confirm operation, check for safe ignition and steady run, and review maintenance points and filter sizing with you.
✓
Clear, written scope and pricing
You get a written plan that spells out what is included—and what is not—before any work begins, so there's no confusion when the job is done.
Details that protect performance
Check Availability
Sizing and installation details that matter (and get missed)
A furnace replacement is often sold like a simple box swap. In practice, the details around that box decide whether the new system is quiet, safe, and reliable.
We pay close attention to:
- ✓Duct and return air capacity: If the duct system cannot support the required airflow, the furnace can overheat and cycle off. We look for undersized returns, blocked grilles, and restrictive filters.
- ✓Venting category and material: High-efficiency furnaces typically use PVC venting and a condensate drain; mid-efficiency commonly uses metal venting to a chimney or B-vent. We match the furnace to the venting path and confirm routing and terminations are appropriate.
- ✓Combustion air and mechanical room conditions: Tight utility rooms, basements, and closets can require specific combustion-air provisions. If the furnace cannot breathe, it cannot run safely.
- ✓Condensate management: On condensing furnaces, we confirm drainage routing, slope, and protection from freezing where lines run through cold areas.
- ✓Filter cabinet and airflow settings: The filter size and blower setup affect noise, comfort, and system life. We set these intentionally, not by guesswork.
You'll see these checks come up more often in parts of Aurora with mixed housing stock. Newer builds can be tighter and more sensitive to combustion-air and airflow issues, while older duct layouts can need adjustments to match a modern blower.

Removal and installation day
We protect the work path, remove the old furnace, set and connect the new unit, update venting or drainage as needed, and reconnect controls and thermostat wiring.
05
Start-up and verification
We run the system through heating operation, confirm proper response at the thermostat, and verify airflow-related setup so the furnace operates as intended.
06
Walkthrough and next steps
You get a clear walkthrough of filter sizing and replacement intervals, what to listen for, and what to do if you ever notice unusual smells, noises, or error codes.

How Much Does Furnace Replacement Cost in Aurora, CO?
Furnace replacement in Aurora typically ranges from $4,500 to $11,000+ depending on furnace efficiency level, size, venting changes, and whether duct, electrical, or condensate work is needed. A straightforward like-for-like replacement with existing compatible venting is usually on the lower end, while a high-efficiency upgrade that requires new venting, drainage, or airflow corrections trends higher.
Your final price is driven most by equipment capacity, venting category changes, accessibility—tight closets versus open basements—filter or return upgrades, and permit or inspection requirements. The exact cost is confirmed after an on-site evaluation of the existing furnace and connections.
Common questions
Furnace replacement FAQs for Aurora homeowners
How long does a furnace replacement take?
Most furnace replacements take 1 day when the new furnace is compatible with the existing venting, gas, and electrical connections. If the job requires venting changes, condensate routing, or airflow corrections, it can take longer depending on access and the amount of rework needed.
Do I need a permit for a furnace replacement in Aurora, CO?
Many furnace replacements require a permit and inspection because gas piping, venting, and combustion safety are involved. If a permit applies to your situation, we include it in the plan so the work is documented and verified rather than left as an uninspected swap.
Should I choose an 80% or a 90%+ (high-efficiency) furnace?
A high-efficiency furnace can be a good fit when the venting route and condensate drainage can be installed correctly for your home. An 80% furnace can still be the right choice when the existing venting path is suited to metal venting and a high-efficiency conversion would require major re-routing. We review venting options and installation constraints first, then recommend the best match.
What are common reasons a new furnace fails inspection or has problems after installation?
The most common issues are venting that does not match the furnace type, missing or incorrect condensate drainage on high-efficiency systems, inadequate return air or restrictive filtration causing overheating, and incomplete start-up setup like blower and control settings. A replacement should include these checks because they affect safety and reliability.
Can you replace a furnace in a tight closet or finished space?
Yes, but tight closets and finished basements require extra planning for safe clearances, combustion air, and a clean work path. We evaluate access before scheduling so we can plan for protective coverings, removal logistics, and any code-related requirements specific to enclosed installations.
What should I do if I smell gas or suspect a carbon monoxide issue?
Treat it as urgent: leave the home and contact your gas utility or emergency services immediately, then arrange an HVAC evaluation once the space is safe. Furnace replacement is often the right decision after a confirmed heat exchanger or combustion safety issue, but safety comes first and must be addressed immediately.
Do you offer warranties on furnace replacement work?
Yes. Furnace replacement typically includes the manufacturer's equipment warranty plus workmanship coverage on the installation. We review what applies to your specific furnace, what maintenance is required to keep coverage in good standing, and what documentation you should keep after the installation.
