Walk into almost any resale home in Colorado Springs built before 2010 and you’ll find one of two things above the stove: a recirculating microwave hood combo that filters almost nothing, or no ventilation at all. Both are common. Neither is doing what most homeowners think it’s doing.
A recirculating hood runs the air through a charcoal filter and sends it right back into the kitchen. It catches some grease and reduces some odor. It does nothing for heat, moisture, or the fine particles and combustion gases that are the real air quality concern — especially with a gas range. A vented hood exhausts all of it outside. The difference in actual kitchen air quality is not subtle.
Here’s what the upgrade involves, what it costs, and what to expect from installation in a Colorado Springs home.
Why Recirculating Hoods Fall Short
Most homeowners assume their range hood is doing the job. In many cases, it isn’t.
Recirculating hoods — also called ductless hoods — pull air through a filter and recirculate it back into the kitchen. The charcoal filter catches some grease and reduces some odors. What it doesn’t remove: heat, moisture, and the fine particles produced by cooking on any stove type.
Research from Lawrence Berkeley National Laboratory found that 60% of U.S. homes with gas stoves exceed legal outdoor pollution limits during cooking. Cooking on any stove — gas or electric — produces fine particulate matter (PM2.5) that can be inhaled deep into the lungs. Gas burners add nitrogen dioxide, carbon monoxide, and formaldehyde from combustion. A recirculating filter doesn’t address any of these — it runs them through a charcoal pad and puts them back in the room.
A vented hood solves this at the source. The air gets pulled up, moved through ductwork, and exhausted outside. Grease, smoke, moisture, heat, and combustion gases leave the building instead of recirculating through your kitchen and into the rest of the house.
The Colorado Springs Kitchen Problem
Two things make kitchen ventilation more relevant here than in most markets.
Grease accumulation. Colorado’s dry climate — indoor winter humidity runs 10–20% RH — means airborne grease particles dry and adhere faster than in humid environments. In a kitchen without proper venting, that grease lands on cabinets, backsplash, walls, and the range itself. Over years, it builds into a film that’s difficult to clean and a fire hazard. Proper venting removes it before it settles.
Gas ranges are common. A significant portion of Colorado Springs homes — particularly those built in the 1980s through 2000s in neighborhoods like Briargate, Broadmoor, and Old North End — have gas ranges. Gas combustion produces nitrogen dioxide and carbon monoxide in addition to the cooking particulates produced by any stove. These are respiratory irritants with documented health effects at the levels produced by indoor cooking without ventilation. Venting directly addresses this.
Ranch-style homes have easy duct paths. Colorado Springs has a high proportion of ranch-style and split-level homes. Many of these have a straight shot from the range to an exterior wall — 3 to 6 feet of duct run, no ceiling penetration, no complex routing. That makes vented hood installation simpler and less expensive here than in markets dominated by two-story builds with interior kitchens.
Types of Vented Range Hoods
Under-cabinet hood. The most common residential option. Mounts to the underside of the cabinet above the range and connects to ductwork running through the cabinet and out the wall or up through the cabinet and ceiling. Straightforward to install in most Colorado Springs kitchens with exterior wall access.
Wall-mounted chimney hood. For ranges on walls without upper cabinets. The hood mounts directly to the wall with a decorative chimney extending to the ceiling. Ductwork runs up through the chimney to the ceiling or out the wall. A popular option in kitchen remodels where upper cabinets have been removed above the range.
Island hood. Hangs from the ceiling above a cooktop on a kitchen island. Requires ductwork through the ceiling joists — the most complex residential installation. Cost is significantly higher than wall or under-cabinet options.
Insert/liner. A blower unit installed inside a custom or decorative hood enclosure. Common in higher-end kitchen remodels where the hood is a design feature built by a carpenter with a commercial-grade blower installed inside.
What Size Hood Do You Need?
Range hood capacity is measured in CFM — cubic feet per minute. The right CFM depends on your range type and kitchen size.
| Situation | Recommended CFM |
|---|---|
| Electric range, standard kitchen | 200 – 300 CFM |
| Gas range, standard kitchen | 300 – 400 CFM |
| High-output gas range (professional style) | 600 – 900 CFM |
| Island installation (add for open volume) | +100 – 150 CFM |
One important ceiling: residential range hoods above 400 CFM can cause negative pressure problems — pulling combustion air back through fireplaces, water heaters, and furnaces. Homes with a high-output gas range that needs 600+ CFM should have a makeup air system installed simultaneously. This is not a common conversation, but it matters in Colorado Springs homes with gas fireplaces and older HVAC systems.
The sweet spot for most Colorado Springs kitchens is 300–400 CFM — enough to handle gas cooking effectively without creating pressure issues.
What Vented Range Hood Installation Involves
Replacement (Existing Ductwork)
The simplest scenario. An existing ducted hood is being swapped for a new one using the same duct connection and electrical outlet.
What’s involved:
- Disconnect and remove old hood
- Mount new hood to cabinet or wall
- Connect to existing ductwork
- Wire to existing outlet or junction box
- Test airflow and verify exterior damper opens
Time: 1–2 hours
Cost: $300–$850 including the hood unit
New Installation — Exterior Wall (No Existing Duct)
The most common scenario in Colorado Springs homes that have never had a vented hood. The range is on an exterior wall or close to one, and duct runs straight through the cabinet and wall.
What’s involved:
- Remove existing recirculating hood or OTR microwave
- Install new hood or mount new hood in cabinet
- Cut through cabinet base and exterior wall for duct penetration
- Install duct run (typically 4–6 inch round or rectangular)
- Install exterior wall cap with backdraft damper
- Wire to existing outlet or run new circuit
- Seal penetration inside and out
Time: 3–5 hours
Cost: $800–$1,800 including hood, ductwork, and labor
New Installation — Interior Wall or Ceiling Route
When the range is on an interior wall and ductwork must travel horizontally through cabinets then up through the ceiling, or route through an adjacent space to reach the exterior.
What’s involved:
- Everything above, plus additional duct runs and possible ceiling work
- May require cutting through drywall and patching
- More elbows and turns reduce airflow efficiency — hood CFM selection needs to account for this
Time: 4–8 hours
Cost: $1,200–$2,500+ depending on route complexity
Island Hood Installation
The most involved residential installation. Ductwork must run through ceiling joists and either exit through the roof or travel to an exterior wall — both require significant ceiling work.
Cost: $1,500–$3,000+ including hood and installation
Ductwork Details That Matter
A vented hood is only as effective as its duct run. A few things that affect performance:
Keep turns to two or fewer. Every 90-degree elbow reduces airflow. A hood rated at 400 CFM with three elbows may be delivering 280 CFM at the damper. Specify smooth-radius elbows where possible and keep the run as direct as possible.
Use the right duct diameter. Most residential hoods take 6-inch round or 3.25 x 10-inch rectangular duct. Reducing to 4-inch significantly restricts airflow and increases noise. Match the duct size to the hood’s collar.
Exterior cap with backdraft damper. The wall or roof cap needs a damper that closes when the hood is off. Without it, cold Colorado air — and occasionally insects — come back through the duct in winter. This is a small detail that gets skipped on cheap installations and creates a noticeable draft.
No flex duct. Flexible aluminum duct is tempting because it’s easy to route around obstacles. It’s also louder, accumulates grease in the corrugations, and restricts airflow. Rigid duct with smooth-radius elbows is the right call.
Permits in Colorado Springs
Mechanical permit (PPRBD): Required when adding new ductwork. The permit process is straightforward for a standard range hood install — plan review is minimal and inspections are typically a single rough-in check.
Electrical permit: Required if a new circuit or outlet is being added. Many hood replacements use an existing outlet and don’t trigger this.
Simple replacement: Usually no permit required if you’re swapping a hood on existing connections with no new ductwork.
When in doubt, call PPRBD. A $100–$150 mechanical permit is not worth skipping — it ensures the installation is correct and doesn’t create a liability at resale.
What to Expect From the Upgrade
The difference between a recirculating hood and a vented one is immediately noticeable. The kitchen clears faster. Cooking smells don’t linger into other rooms. The cabinets above the range stop accumulating that film of dried grease. In winter, when Colorado Springs homes are sealed up tight against the cold, the air quality difference is most pronounced — cooking pollutants that used to recirculate through the house are now exhausted outside.
For homes with gas ranges, the upgrade is more than a comfort improvement. It’s the difference between cooking in a ventilated space and cooking in one where combustion byproducts have nowhere to go.
Most Colorado Springs kitchens — particularly the ranch-style homes that make up a large portion of the housing stock — can be vented with a straightforward exterior wall installation. It’s one of the higher-value upgrades available for the cost.
