Efficiency & refrigerant
Refrigerant type was not published for this listing. Note the 2025 transition: new residential systems must now use low-GWP refrigerant (R-454B or R-32) under the EPA AIM Act, while existing R-410A units remain serviceable.
Rebates & tax credits
This category does not have its own line in the federal 25C tax credit. Some matched-system components may still factor into a qualifying installation — confirm with your installer. See the federal credit details →
This is not tax advice. We do not know this exact model's certified efficiency rating, so we cannot say it qualifies for any specific amount. Eligibility depends on the installed system's AHRI-matched rating, your tax liability, and the home being your residence. Always confirm with your installer and a tax advisor.

Matched systems (AHRI)

A retailer "system bundle" is not proof of an AHRI reference number. Verify the match in the AHRI Directory.
Before you buy or install
A dehumidifier is sized by pints-per-day to the space and its moisture load. Confirm the drainage method (bucket vs continuous/pump), the operating temperature range, and the electrical requirements. Whole-home models tie into ductwork and should be installed by an HVAC contractor; portables are owner-installable.
Maintenance
Clean the filter regularly, wipe the coils, and keep the drainage path clear. Check that the humidistat reflects actual room humidity.
Quest qu13366 — questions
How much does the Quest qu13366 cost?
It's listed from $8,830 — the lowest of 2 retailers — with a typical range of $8,830 to $8,830 (median $8,830). That's the equipment price; a full installed system costs more.
Is that the installed price?
No — this is the equipment (box) price. A full installed industrial and commercial dehumidifiers (matched components, labor, permits) costs significantly more, and that install markup is where quotes vary most.
Does the Quest qu13366 qualify for a federal tax credit?
The federal 25C credit applied only to systems placed in service on or before December 31, 2025, so it does not apply to new installs after that date. State and utility rebates (via DSIRE) may still apply — confirm eligibility with your installer and a tax advisor.
