Frequently Asked Questions
Answers to common questions about DEPLUS products, warranty, installation, and dealer partnerships.
Depending on the matched system configuration, DEPLUS inverter systems achieve Up to 20 SEER2. All ratings are AHRI-certified and published in the AHRI directory, paired with the matched air handler for the system configuration.
DEPLUS residential and light commercial systems use R-454B refrigerant (air conditioners and air handlers) and R-32 (packaged units), both factory-charged at the time of manufacture. These next-generation refrigerants meet current efficiency and environmental standards.
For optimal efficiency and AHRI-certified ratings, DEPLUS condensers should be matched with DEPLUS air handlers. The published SEER2, EER2, and HSPF2 ratings are specific to tested matched pairs. The equipment can be installed with third-party coils, but unverified matched ratings should not be used on submittals or energy compliance documentation.
Yes. The DP-CF36UUMR2 Packaged Unit is engineered for light commercial applications including retail, small office, and multi-family common area installations. It carries ETL listing for commercial use and is rated for continuous duty cycles. Consult the submittal sheet for electrical and structural mounting specifications.
AHRI certificates for all certified DEPLUS matched systems are available through the AHRI directory at ahridirectory.org. Search by the DEPLUS model number. Certificates can also be requested directly by contacting us at info@deplusworld.com.

The warranty covers manufacturing defects in materials and workmanship. It covers the compressor (up to 10 years), coil (up to 10 years), and all other functional parts (up to 10 years) under the extended registered warranty. Labor is not included — labor coverage is the responsibility of the installing contractor or a separate service contract.
Yes, the DEPLUS limited warranty is transferable to a subsequent owner of the property for the remainder of the original warranty period. Contact support.deplusworld.com to update the ownership record at the time of property transfer.
The following actions void the warranty: installation by an unlicensed HVAC contractor, modification or alteration of the equipment, use of non-approved refrigerant, failure to maintain proper system refrigerant charge, physical damage, use in applications beyond the rated operating range, or failure to perform manufacturer-recommended maintenance intervals.
Yes. All DEPLUS HVAC systems must be installed by a licensed HVAC contractor to maintain warranty coverage and ensure compliance with local mechanical codes. This typically means EPA 608 certification for refrigerant handling and a state-issued contractor license. DIY installation voids the warranty.
Line set sizing depends on the system capacity and run length. For 1.5–2.5 Ton systems, 3/8" liquid and 3/4" suction is standard. For 3.0–5.0 Ton systems, 3/8" liquid and 7/8" suction is required. For runs over 50 feet, consult the DEPLUS line set sizing guide or contact technical support. Improper line sizing is a leading cause of efficiency loss and premature compressor failure.
Yes. The DP-AH24SMR4 Multi-Position Air Handler is designed for upflow, downflow, and horizontal installation without field modification. The drain pan, coil section, and blower are all orientation-compatible from the factory. Follow the orientation-specific condensate drain instructions in the installation manual for each configuration.
