The catch
Santa Fe Compact70
Optional ducting for a dedicated space does not turn it into an HVAC-integrated substitute for Ultra70.
Side by side
Santa Fe Compact70 vs Ultra70: Ultra70 supports the HVAC route, Compact70 is shorter
Quick verdict
Compact70 suits a dedicated crawlspace or basement where its seven-inch-shorter body is valuable. Ultra70 is the better match for a documented HVAC-integrated design. Support for documented HVAC integration is what Ultra70 offers, while Compact70 targets a dedicated space. Both current A2L versions have 70-pint ratings at 80 F and 60% RH, 12-inch-high bodies and external trap requirements. A duct accessory alone does not make their intended installations interchangeable.
Before you buy
Why, and what it costs you
One pint rating can be used for two different air-distribution jobs
For moisture control inside a sealed crawlspace, Compact70’s dedicated-space role and shorter body can be a fit. For distributing treated air through the home’s HVAC system, Ultra70 is the one with the documented integration route. Buying the smaller unit and adding a duct collar does not supply the missing control and airflow design. Closed rooms still need a valid air path. Settle on the intended system before deciding which 70-pint label looks like the better offer.
Where this comes from
The manufacturer's intended use, set against dedicated-space versus whole-home distribution. Being ductable is not treated as the same as HVAC integration.
The catch
Santa Fe Ultra70
At seven inches longer, the body still needs room for its raised trap arrangement and filter access.
Santa Fe Compact70
- Why pick it
- You are dealing with a dedicated space, and the shorter cabinet fits the complete installation.
- You have no use for the HVAC integration route of Ultra70.
- The catch
- Optional ducting for a dedicated space does not turn it into an HVAC-integrated substitute for Ultra70.
Santa Fe Ultra70
- Why pick it
- Your installer is working out documented HVAC integration or the supported ventilation arrangement.
- The longer body, trap and service space all fit.
- The catch
- At seven inches longer, the body still needs room for its raised trap arrangement and filter access.

What this page compares
Santa Fe Compact70 vs Ultra70 current A2L models for a crawlspace or ducted home. Behind the equal 70-pint ratings sit different air paths and installation needs.
A low body height and weight are shared by these two current Santa Fe 70-pint units. If you are comparing them, understand where each one is meant to send the treated air.

Expecting a short cabinet to weigh less as well
At 55 lb each, both current bodies weigh the same. Compact70 saves length but does not lower the stated carrying weight.

Differences you will notice

How we worked this out
The manufacturer's intended use, set against dedicated-space versus whole-home distribution. Being ductable is not treated as the same as HVAC integration.
Seven inches saved can count for more than a low height both units share
Height is 12 inches and weight 55 lb for both bodies, but Compact70 is 21 inches long against Ultra70’s 28. That seven-inch length difference may be the useful physical advantage in a crawlspace broken up by beams, supports or stored equipment. A trap and service clearance are still required for both. For the trap arrangement, Ultra70’s current manual specifically raises its base six inches above the secondary drain pan. Measure the whole installation instead of assuming either fits a 12-inch gap.
How we worked this out
28 - 21 gives seven inches of length. Equal body height and weight, set against obstacles and drain installation. No universal installed-height winner is named.
The cooler-condition numbers for the two cannot settle a cold-space comparison
A cooler rating at 65 F is listed for Compact70, while the current Ultra70 page lists its second rating at 73 F. Relative humidity is 60% in both, but the temperatures differ. Setting 43.7 against 52.45 as if they came from one test would produce a false performance gap. The matched 80 F ratings are equal. For a cooler site, use the current operating requirements and ask for genuinely matched data, and do not pay for an apparent advantage that different test conditions created.
How we worked this out
The temperature mismatch is identified before any percentage is computed. Current A2L records are kept apart from earlier refrigerant revisions.

Spec by spec
Where they really differ
| Spec | Santa Fe Compact70 | Santa Fe Ultra70 | In practice |
|---|---|---|---|
| Intended air path | Dedicated-space use, optional dedicated-space duct kit | Documented HVAC integration and optional outdoor-air ventilation | Whole-home use is not shown to be the same just by the connection hardware. |
| Body | 12 W × 21 D × 12 H inches | 12 W × 28 D × 12 H inches | Compact70 has a body seven inches shorter. |
| Warm-condition rating | 70 pints at 80 F and 60% RH | 70 pints at 80 F and 60% RH | The common rating gives neither one a capacity advantage. |
| Cooler published point | About 43.7 pints at 65 F and 60% RH | 52.45 pints at 73 F and 60% RH | A fair ranking at cooler conditions is ruled out by the different temperatures. |
Trade-offs
What each pick costs you

- Count in current A2L installation checks, replacement filters, the trap and any optional duct kit or pump.
With Santa Fe Ultra70
- The job grows with ducts, control integration, pan protection and optional ventilation components.
Change of plan
When the answer changes
The shorter body is what a dedicated space needs
Go with Santa Fe Compact70. Seven inches of length is what Compact70 saves.
Documented HVAC integration is what the job requires

Decision guide
Before you buy
You want one low-profile unit, though drying a crawlspace and distributing dry air through the home call for different routes.
