Main trade-off
Santa Fe Compact70
Optional dedicated-space ducting does not make it an HVAC-integrated substitute for Ultra70.
Head-to-head
Choose Compact70 for a dedicated crawlspace or basement where its seven-inch-shorter body is valuable. Choose Ultra70 for a documented HVAC-integrated design. Ultra70 supports documented HVAC integration, 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 choose
If the goal is moisture control within a sealed crawlspace, Compact70’s dedicated-space role and shorter body can be appropriate. If the goal is to distribute treated air through the home’s HVAC system, Ultra70 provides the documented integration route. Buying the smaller unit and adding a duct collar does not establish the missing control and airflow design. Closed rooms still need a valid air path. Select the intended system before deciding which 70-pint label looks like the better offer.
What this is based on
Manufacturer intended use crossed with dedicated-space versus whole-home distribution. Ductability is not treated as interchangeable HVAC integration.
Main trade-off
Optional dedicated-space ducting does not make it an HVAC-integrated substitute for Ultra70.
Main trade-off
The body is seven inches longer. Its raised trap arrangement and filter access still need room.


Santa Fe Compact70 vs Ultra70 current A2L models for a crawlspace or ducted home. Equal 70-pint ratings hide different air paths and installation needs.
These two current Santa Fe 70-pint units share a low body height and weight. Buyers comparing them need to understand where each is intended to move the treated air.
Winner by situation
Compact70 is seven inches shorter.
Ultra70 provides the intended integration route.
The secondary published temperatures differ.
Both current bodies weigh 55 lb. Compact70 saves length without reducing the stated carrying weight.

Both bodies are 12 inches high and weigh 55 lb, but Compact70 is 21 inches long against Ultra70’s 28. In a crawlspace interrupted by beams, supports or stored equipment, that seven-inch length difference may be the useful physical advantage. Both still require a trap and service clearance. Ultra70’s current manual specifically raises its base six inches above the secondary drain pan for the trap arrangement. Measure the whole installation rather than assuming either fits a 12-inch gap.
28 - 21 equals seven inches length. Equal body height and weight crossed with obstacles and drain installation. No universal installed-height winner.
Compact70 lists a cooler rating at 65 F, while the current Ultra70 page lists its second rating at 73 F. Both use 60% relative humidity, but the temperatures differ. Comparing 43.7 and 52.45 as though they came from one test would create 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 rather than paying for an apparent advantage created by different test conditions.
Temperature mismatch identified before computing a percentage. Current A2L records kept separate from earlier refrigerant revisions.

Meaningful differences
| What changes | Santa Fe Compact70 | Santa Fe Ultra70 | Why it matters |
|---|---|---|---|
| Intended air path | Dedicated-space use, optional dedicated-space duct kit | Documented HVAC integration and optional outdoor-air ventilation | Connection hardware alone does not establish the same whole-home use. |
| Body | 12 W × 21 D × 12 H inches | 12 W × 28 D × 12 H inches | Compact70 is seven inches shorter. |
| Warm-condition rating | 70 pints at 80 F and 60% RH | 70 pints at 80 F and 60% RH | No capacity advantage follows from the common rating. |
| Cooler published point | About 43.7 pints at 65 F and 60% RH | 52.45 pints at 73 F and 60% RH | Different temperatures prevent a fair cooler-condition ranking. |
What you give up
Recommendation switch
Choose Santa Fe Compact70. Compact70 saves seven inches in length.
Choose Santa Fe Ultra70. Ultra70 supports that route.
What matters in practice
You want one low-profile unit, but drying a crawlspace and distributing dry air through the home require different routes.
