As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
If you are comparing 1hvac 5 ton 13 8 seer2 alternatives, you likely need high cooling capacity for a large space. The original 1HVAC unit offers 5 tons of cooling and 13.8 SEER2 efficiency in a vertical configuration. It includes a programmable thermostat and uses R32 refrigerant for modern efficiency standards. AHRI certification and ETL listing add a layer of safety and reliability for your installation.
However, you might prefer a different setup. The alternatives on this list feature multi-zone capabilities, allowing you to control temperatures in separate rooms. Some models offer significantly higher SEER2 ratings, such as 21 or 22, which can reduce energy consumption. Others provide quintuple or quad-zone configurations to match your home layout. We selected these 6 options because their specifications overlap with the 1HVAC unit in cooling capacity or zone flexibility, giving you practical choices based on your specific needs.
Our top pick: 1HVAC 5 Ton 13.8 SEER2 Central AC.
Key differences in specs
TOSOT Cosmo 36K BTU Quad Zone
The TOSOT Cosmo 36K BTU Quad Zone replaces the 1HVAC’s single-zone central design with four independent zones. It delivers 21 SEER2 efficiency, which is significantly higher than the 1HVAC’s 13.8 SEER2 rating. This unit uses four 9,000 BTU indoor units for precise temperature control in separate rooms. The outdoor condenser is compact, measuring 16.8 inches wide and 32.5 inches high. You gain flexibility in managing different room temperatures, but you give up the simple whole-house approach of the 1HVAC system. This alternative is best for homeowners who need detailed climate management across multiple areas rather than uniform cooling for one large space.
Senville 36k BTU 4-Zone Mini Split
The Senville 36k BTU 4-Zone Mini Split offers quad-zone control with four 9,000 BTU indoor units. It focuses on cold-climate performance, making it a strong choice for heating in harsh winters compared to the 1HVAC’s cooling-centric design. The outdoor unit is larger, measuring 40 inches wide and 60 inches high. It supports smart voice integration for easier control. You trade the 1HVAC’s included programmable thermostat and AHRI certification for multi-zone flexibility and robust heating capabilities. This model suits buyers who need distinct climate zones and reliable heating in low temperatures, prioritizing comfort across several rooms over the simplicity of a single central unit.
TURBRO 5-Zone 42K BTU Mini Split
The TURBRO 5-Zone 42K BTU Mini Split provides five independent zones with five 9,000 BTU indoor units. It achieves 22 SEER2 efficiency, outperforming the 1HVAC’s 13.8 SEER2 rating by a wide margin. The outdoor unit is wider at 45.4 inches but thinner at 11.5 inches. It includes app management for remote control, which the 1HVAC’s basic thermostat does not offer. You gain superior energy efficiency and granular zone control but lose the straightforward central AC setup. This alternative is ideal for large homes needing precise temperature adjustments in five separate areas, where high efficiency and smart features are more valuable than the original’s basic functionality.
Della 35K BTU 4-Zone Mini Split
The Della 35K BTU 4-Zone Mini Split features four zones with a mix of 9,000 and 12,000 BTU indoor units. It offers 19 SEER2 efficiency, which is better than the 1HVAC’s 13.8 SEER2 but lower than top-tier models. The unit is compact, measuring 31.9 inches wide and 11.5 inches high. It includes Alexa integration for voice control, adding convenience over the 1HVAC’s standard thermostat. You get multi-zone flexibility and smart home compatibility but sacrifice the higher efficiency and central air simplicity. This option fits homes needing four distinct zones with voice control, offering a balance of performance and smart features without the bulk of larger central systems.
Della 35K BTU 3-Zone Mini Split
The Della 35K BTU 3-Zone Mini Split provides three zones with varying capacities: 9,000, 12,000, and 18,000 BTU. It matches the 19 SEER2 efficiency of the other Della model, beating the 1HVAC’s 13.8 SEER2. The outdoor unit shares the same compact dimensions as the 4-zone version. It includes Alexa integration but lacks app support and self-cleaning features. You gain targeted cooling for three rooms with smart voice control, giving up the 1HVAC’s whole-house uniformity. This alternative suits users who need separate climate control for three specific areas and value Alexa compatibility, accepting the trade-off of fewer zones and missing advanced features like app management.
MrCool DIY 36K BTU Mini Split
The MrCool DIY 36K BTU Mini Split is a single-zone unit, similar in scope to the 1HVAC’s central design but with mini-split technology. It offers high efficiency, though specific SEER2 ratings are not listed, it is noted for robust performance. The outdoor unit is 21 inches wide and 45 inches high. It includes a complete installation kit, simplifying setup for DIYers compared to the 1HVAC’s separate kit options. You gain a user-friendly installation process and reliable single-zone cooling, trading the 1HVAC’s included thermostat and AHRI certification for ease of use and compact design. This model is best for those who prefer a straightforward DIY install without managing multiple zones or complex central air components.
