Note: There are dual 7-segment LED's adjacent to the selection dipswitches. The airflow rounded to the nearest 100 CFM, is displayed on the dual 7-segment LED's. The CFM display alternates with the operating mode.

Example:

If the airlfow demand is 1230 CFM, the LED's will display 12. If the airflow demand is 1275 CFM, the LED's will display 13.

Note: Continuous fan speed will be 30% of the furnace's maximum airflow capability. If the fur- nace maximum CFM capaibility is 1760 CFM, the continuous fan speed will be 0.30 X 1760 CFM = 530 CFM.

Example: If the furnace maximum CFM capaibility is 1760 CFM, the continuous fan speed will be 0.30 X 1760 CFM = 530 CFM.

Note: The optional usage of a dehumidistat allows the furnace’s circulator blower to operate at a slightly lower speed (85% of desired speed) during a combined thermostat call for cooling and dehumidistat call for dehumidification. This can be done through an independent dehumidistat or through a thermostat’s DEHUM terminal (if available). This lower blower speed enhances dehumidification of the conditioned air as it passes through the AC coil. For proper function, a dehumidistat applied to this furnace must operate on 24 VAC and utilize a switch which opens on humidity rise.

1.Units are shipped without filter(s). CFM in chart is without filter(s).

2.All furnaces shipped with heating speed set at "B" and cooling speed set at "D". Installer should adjust blower speed as needed. The first task is to determine the proper aiflow for the cooling system.

3.For most cooling applications, about 400 CFM per ton is desirable.

4.The chart is for information only. For satisfactory operation, external static pressure not to exceed value shown on rating plate.

5.Do not operate above 0.5" w.c. ESP in heating mode. Operating between 0.5" w.c. and 0.8" w.c. is tabulated for cooling purposes only.

6.* Motor CFM minimum.

Goodman 90%-95% Gas Furnace Units, ACVC9/AMVC95, GCVC9/GMVC95 specifications

Goodman Manufacturing is a prominent name in the HVAC industry, known for providing energy-efficient solutions that cater to both residential and commercial environments. Among its offerings, the Goodman GCVC9/GMVC95 and ACVC9/AMVC95 models stand out as top-tier gas furnace units, with efficiency ratings between 90% and 95%. These furnaces provide an excellent balance of performance, reliability, and affordability.

The GCVC9 and GMVC95 gas furnace units are designed with advanced features that ensure optimal heating and comfort. One of the key characteristics of these models is their energy efficiency. With Annual Fuel Utilization Efficiency (AFUE) ratings of up to 95%, these furnaces convert nearly all the fuel they consume into heat, resulting in significant cost savings on energy bills. This makes them an ideal choice for homeowners looking to reduce their carbon footprint while maintaining a comfortable indoor environment.

These units are equipped with a two-stage gas valve and a variable-speed blower motor. The two-stage gas valve allows for precise temperature control by providing two levels of heating output, ensuring that the furnace runs at lower capacities during milder conditions and ramping up when more heat is needed. The variable-speed blower motor enhances comfort by providing consistent airflow, reducing temperature fluctuations, and operating more quietly than single-speed motors.

Another notable feature is the firing system, which utilizes a hot surface igniter for reliable operation. This technology enhances safety and performance, eliminating the need for a pilot light and minimizing gas waste. Additionally, both models are designed for easy installation and maintenance, with features like a compact design and convenient access to internal components.

Durability is also a hallmark of Goodman furnaces. The units are constructed with high-quality materials, including a heavy-gauge steel cabinet and a durable powder-coated finish to resist corrosion. Furthermore, Goodman offers exceptional warranties, including a lifetime heat exchanger warranty, providing peace of mind for homeowners.

In conclusion, the Goodman GCVC9/GMVC95 and ACVC9/AMVC95 gas furnace units are engineered for efficient heating with advanced technologies that enhance performance and comfort. Their high AFUE ratings, reliable ignition system, and durable construction make them excellent choices for anyone looking to invest in a reliable heating solution. With Goodman at the helm, homeowners can enjoy efficient heating without compromising on comfort or cost.
