Review
The ACiQ 3.5 ton horizontal furnace and air conditioner system addresses a specific installation challenge: delivering efficient comfort in tight spaces. This unit combines a 120,000 BTU furnace with 42,000 BTU cooling capacity while maintaining a compact 24.5 inch height, 26 inch width, and 21.125 inch depth. It's designed for contractors who encounter real-world constraints where standard vertical furnaces simply won't fit. The combination of high heating efficiency and adequate cooling makes this a practical choice for replacement markets across moderate climates.
The furnace delivers 97% AFUE efficiency through a modulating burner that continuously adjusts output rather than cycling fully on and off. This means less energy waste and steadier home temperature. The air conditioning side produces 14 SEER with R410A refrigerant and a scroll compressor, cooling at 42,000 BTU. A variable-speed ECM blower motor handles airflow up to 2000 CFM while consuming only the power needed at any given moment. These specifications work together to reduce both gas and electric bills, though the single-stage condenser operates at one fixed capacity during cooling cycles.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means minimal gas waste and lower heating bills, among the best available in horizontal configs
- Modulating burner adjusts output continuously rather than cycling on-off, improving comfort and efficiency
- Variable-speed ECM blower motor reduces energy consumption and adapts airflow to actual heating/cooling demand
- Horizontal-only design solves real space problems where vertical furnaces physically won't fit
- PVC flue compatibility simplifies venting in tight installations compared to metal ductwork
- 10-year warranty with online registration covers parts and compressor protection
Cons
- 14 SEER cooling lags behind newer 16+ SEER units; competitive but not cutting-edge for AC-heavy markets
- No Energy Star certification despite high heating efficiency, missing potential rebate qualification
- Single-stage condenser cannot modulate cooling like heating side does, limiting part-load efficiency
Who Should Buy
Best For
Contractors installing replacement systems in homes with cramped attics, basements, or mechanical closets where a standard 30-inch upflow furnace won't fit. Homeowners in northern climates who prioritize heating efficiency and want to minimize natural gas consumption during cold winters.
Consider Alternatives If
Buyers seeking maximum cooling efficiency for hot climates should compare higher SEER options. Those prioritizing Energy Star rebates will find certified alternatives that may offer better overall incentives.
Installation
Horizontal installation requires careful ductwork planning since the unit feeds conditioned air sideways rather than upward. PVC flue compatibility simplifies venting through exterior walls or roofs. The right-side flue location must be verified against your existing framework. Electrical needs include 208/230 volt, single-phase power with breaker sizing between 22 and 35 amps. Pre-installation checks must confirm adequate return air pathways and proper clearance around the 120-pound unit.
Warranty & Reliability
ACiQ provides 10 years of parts and compressor coverage when you complete online registration after purchase. No registration means coverage exists but at reduced terms. This is above-average protection for mid-tier equipment. Coverage begins at installation. Read the CHPF specifications sheet and installation manual carefully, as warranty voids apply for improper sizing or installation. A registered warranty becomes valuable if major component failures occur within the decade.
