Goodman 100,000 BTU 80% Efficiency Upflow, Horizontal Gas Furnace Model GMES801005CN

The Goodman GMES801005CN is a natural gas furnace designed to provide reliable heating with a capacity of 100,000 BTUs. It has an AFUE (Annual Fuel Utilization Efficiency) rating of 80%, meaning it converts 80% of the fuel it uses into heat. This efficiency level is standard but not the most energy-efficient option available, so it might cost more in fuel over time compared to higher-efficiency models.

The furnace uses a corded electric ignition system, which is more reliable and safer compared to older pilot light systems. With a noise level of 56 dB, the furnace operates relatively quietly, making it a good fit for households where noise is a concern. One of its strong points is the 10-year parts limited warranty, provided it is installed by a qualified professional and registered online within 60 days.

Buying Guide for the Best Natural Gas Furnaces

Choosing the right natural gas furnace for your home is crucial for ensuring comfort, energy efficiency, and cost savings. When selecting a furnace, it's important to consider several key specifications that will determine how well the furnace meets your needs. Understanding these specifications will help you make an informed decision and find the best fit for your home.
AFUE (Annual Fuel Utilization Efficiency)AFUE measures how efficiently a furnace converts fuel into heat over the course of a year. It is expressed as a percentage, with higher percentages indicating greater efficiency. Furnaces with an AFUE of 90% or higher are considered high-efficiency models, while those with an AFUE between 80% and 89% are mid-efficiency. If you live in a colder climate or want to reduce your energy bills, a high-efficiency furnace is a good choice. For milder climates, a mid-efficiency furnace may be sufficient.
Heating Capacity (BTUs)Heating capacity, measured in British Thermal Units (BTUs), indicates the amount of heat a furnace can produce. This spec is important because it determines how well the furnace can heat your home. Furnaces typically range from 40,000 to 200,000 BTUs. To choose the right capacity, consider the size of your home, insulation quality, and climate. A professional can perform a heat load calculation to determine the appropriate BTU rating for your specific needs.
Blower Motor TypeThe blower motor circulates air through your home's ductwork. There are two main types: single-speed and variable-speed. Single-speed motors operate at one constant speed, while variable-speed motors can adjust their speed to match heating demands. Variable-speed motors are more energy-efficient and provide better temperature control and quieter operation. If you value energy savings and comfort, a furnace with a variable-speed motor is a good choice. For simpler needs, a single-speed motor may suffice.
Ignition SystemThe ignition system is responsible for lighting the furnace's burners. There are two main types: standing pilot and electronic ignition. Standing pilot systems have a continuously burning flame, while electronic ignition systems use an electric spark or hot surface to ignite the burners only when needed. Electronic ignition systems are more energy-efficient and reliable. If you want a more modern and efficient furnace, opt for one with an electronic ignition system.
Noise LevelNoise level refers to how loud the furnace operates. This is important for maintaining a comfortable and quiet home environment. Noise levels are typically measured in decibels (dB). Furnaces with noise levels below 70 dB are considered quiet. If you are sensitive to noise or have living spaces near the furnace, look for models with lower noise levels. For less critical areas, noise may be less of a concern.
WarrantyA warranty provides coverage for repairs or replacements if the furnace malfunctions. Warranties vary in length and coverage, typically ranging from 5 to 20 years. A longer warranty can offer peace of mind and protect your investment. When choosing a furnace, consider the warranty terms and what is covered. If you plan to stay in your home for many years, a furnace with a longer warranty may be beneficial.
