Review
ACiQ's 3.5-ton gas furnace and air conditioning system combines practical efficiency with straightforward installation for residential HVAC applications. This upflow configuration delivers 120,000 BTU heating capacity and 42,000 BTU cooling output, addressing the needs of mid-sized homes across moderate climates. With 97% AFUE furnace efficiency and Energy Star certification, it positions itself as a capable mid-tier option between budget units and premium systems costing significantly more.
The furnace's modulating burner stages adapt to heating demand, reducing energy waste during partial-load operation. The variable-speed ECM blower motor automatically adjusts CFM up to 2,000 to match cooling and heating requirements, improving comfort consistency. The 13 SEER air conditioning condenser operates as a single-stage reciprocating compressor using R410A refrigerant, qualifying for Energy Star recognition. At 75 dB during operation, noise levels remain acceptable for most residential settings, though not silent.
Pros & Cons
Pros
- 97% AFUE furnace efficiency reduces heating costs significantly compared to standard 80% units
- Modulating burner stages provide precise temperature control and quieter operation than single-stage alternatives
- Variable-speed ECM blower motor automatically adjusts airflow, improving comfort and reducing energy waste
- 13 SEER rating meets Energy Star certification for federal tax credit eligibility
- 10-year warranty with online registration provides peace of mind on major components
- Plastic/PVC exhaust flue requirement simplifies venting and lowers installation complexity compared to metal ductwork
Cons
- Single-stage air conditioning condenser limits efficiency in hot climates where two-stage cooling performs better
- 75 dB noise level at rated capacity may be noticeable in quiet residential settings
- Reciprocating compressor is less efficient than scroll designs found in premium competitor models
- Propane conversion requires additional kit and setup beyond standard natural gas configuration
Who Should Buy
Best For
Homeowners replacing aging furnaces in climate zones with moderate heating and cooling seasons, particularly those prioritizing heating efficiency. Contractors installing complete systems in new construction or major renovations where upflow/horizontal configuration suits existing ductwork.
Consider Alternatives If
Customers in predominantly hot climates should explore two-stage cooling systems, and those wanting whisper-quiet operation may prefer scroll compressor units despite higher cost.
Installation
Installation suits both horizontal and upflow configurations with standard ductwork. The plastic/PVC exhaust flue requirement simplifies venting compared to metal alternatives, reducing labor time. Electrical requirements are modest, needing only 115V single-phase 60 Hz service with 23.9 to 40-amp breaker sizing. Line sets accommodate standard 3/8-inch liquid and 7/8-inch suction lines with 3/8-inch insulation thickness over 30 feet.
Warranty & Reliability
The system includes a 10-year comprehensive warranty activated through online registration, covering parts and compressor. This aligns with industry standards for mid-tier equipment, providing reasonable protection against manufacturing defects. Online registration requirement takes minutes and unlocks full coverage, making it accessible to most buyers.
