// Bottom Line
This is an excellent choice for homeowners replacing older systems on a budget who want respectable efficiency without premium pricing. The 18 SEER rating and two-stage cooling make it ideal for moderate climates where air conditioning demand is consistent but not extreme.

Review

Goodman's horizontal CHPF4860D6 combo system bridges affordability and performance in a crowded market. At $2160, it undercuts many competitors while delivering respectable 18 SEER cooling and 80,000 BTU heating capacity. The unit earned Energy Star status and includes a 10-year warranty with online registration. This system targets homeowners seeking legitimate efficiency upgrades from older single-stage equipment without committing to premium pricing that often exceeds $3000.

The cooling side impresses with an 18 SEER rating, two-stage scroll compressor, and 35,000 BTU output. Two-stage burner operation on the heating side keeps the 80% AFUE furnace from constant cycling, improving comfort during partial-load conditions. The variable-speed blower runs up to 2000 CFM and operates at a reasonable 71 dB. Electrical requirements are modest at 120V single-phase, 60Hz, with a breaker range of 21.9 to 35 amps, making retrofit installations straightforward in most homes.

Pros & Cons

Pros

  • 18 SEER cooling efficiency earns Energy Star certification, reducing summer cooling costs significantly
  • Two-stage compressor and two-stage burners optimize runtime and reduce energy waste during partial-load operation
  • 80,000 BTU furnace with 80% AFUE handles heating adequately for mild-to-moderate winters without excessive fuel consumption
  • Variable-speed blower motor adjusts airflow from 0 to 2000 CFM for better comfort control and humidity management
  • Horizontal configuration with A-coil design allows flexible installation in attics, basements, or tight spaces
  • Scroll compressor technology is proven reliable and quieter than alternatives, running at 71 dB

Cons

  • 80% AFUE is serviceable but not competitive with 95%+ AFUE high-efficiency models for heating-dominant climates
  • Spec sheet lists 5-ton tonnage while product title claims 3-ton, creating confusion about actual cooling capacity and system sizing
  • R410A and R22 refrigerant compatibility adds complexity during service calls and potential future phase-out concerns with R22

Who Should Buy

Best For

Homeowners in moderate climates where cooling needs outweigh heating demands should seriously consider this unit. It works particularly well for those replacing 10-15 year old systems who want solid efficiency gains and two-stage operation without spending $3500 or more on premium equipment.

Consider Alternatives If

Skip this if you live in a heating-dominant climate or need ultra-high efficiency, as the 80% AFUE furnace won't deliver the fuel savings of condensing models.

Installation

Installation complexity is moderate. The horizontal configuration fits attics or basements easily, and sweat valve connections with standard 3/8-inch liquid line and 7/8-inch suction line follow industry norms. Metal exhaust flue is required for the furnace. Technicians should verify ductwork sizing matches the variable-speed blower's capability. Most installations take 4 to 6 hours including refrigerant charging and commissioning.

Warranty & Reliability

Goodman provides 10 years of parts coverage when you register online within 60 days of installation. This is solid mid-market coverage that protects against compressor failure, heat exchanger cracks, and component defects. Labor coverage typically requires extended plans purchased separately. Registration is straightforward and extends protection considerably beyond standard one-year coverage.

Frequently Asked Questions

What's the actual tonnage of this system, given the confusing 3-ton versus 5-ton specs? +
The 35,000 BTU cooling capacity and specs align with 3-ton rating. The 5-ton notation in specs appears to be a data entry error. Always verify with the AHRI certificate (204633307) when sizing. Contact Goodman directly if spec uncertainty affects your decision.
Can I install this horizontally in my attic with standard ductwork? +
Yes, the horizontal A-coil configuration works well in attics. Ensure ductwork supports 2000 CFM maximum airflow and that return air is unrestricted. Have your contractor verify existing ducts can handle the variable-speed blower output without pressure issues.
How much will my heating costs drop compared to my old 60% AFUE furnace? +
An 80% AFUE unit delivers roughly 25 to 30 percent fuel savings versus 60% equipment. Actual savings depend on climate, gas prices, and thermostat settings. In mild climates where you run heat sparingly, annual savings may only be $150 to 200.
Is 18 SEER still competitive in 2024, or should I spend more for higher ratings? +
18 SEER remains efficient and cost-effective. 20+ SEER units cost significantly more but save perhaps 10 to 12 percent in cooling energy. The payback on premium SEER ratings often exceeds 10 years, making 18 SEER sensible for most buyers.
What does the 10-year warranty actually cover if my compressor fails? +
Parts are covered fully at no cost with registration. Labor costs are your responsibility unless you purchased an extended service agreement. Most contractors charge $300 to 600 for compressor replacement labor separately.
