What are Low NOx Emissions?

Table of Contents


When it comes to choosing an AC or furnace system for your home, there are many factors to consider. One important consideration is the system’s emissions, specifically the level of NOx emissions. NOx stands for nitrogen oxide, which is a harmful pollutant that contributes to smog and respiratory issues.

In recent years, there has been a growing focus on reducing NOx emissions from heating and cooling systems. This has led to the development of low NOx AC and furnace systems, which are designed to minimize the release of harmful pollutants into the environment.

How Do Low NOx Emissions Work?

Low NOx AC and furnace systems use advanced combustion technology to reduce nitrogen oxide emissions. These systems rely on a combination of design features and components that allow for more efficient combustion, resulting in lower NOx emissions.

One key feature of low NOx systems is a specially designed burner that helps to promote more complete combustion. This reduces the amount of nitrogen oxide that is produced during the combustion process.

In addition to the burner, low NOx systems also include features such as advanced air-to-fuel ratio control and improved heat exchanger designs. These features help to optimize the combustion process and minimize the formation of nitrogen oxide.

Benefits of Low NOx Emissions

There are several benefits to choosing a low NOx AC or furnace system for your home:

  • Reduced Environmental Impact: By choosing a system with low NOx emissions, you are helping to minimize your carbon footprint and reduce the impact of harmful pollutants on the environment.
  • Improved Air Quality: Low NOx systems help to improve indoor air quality by reducing the amount of nitrogen oxide and other harmful pollutants that are released into the air.
  • Regulatory Compliance: Many areas have strict regulations on NOx emissions, especially in areas with high levels of air pollution. Choosing a low NOx system ensures that your home remains compliant with these regulations.

Low NOx AC & Furnace Systems Features

When it comes to low NOx AC and furnace systems, there are several different features and options to consider. These include:

  1. Best Warranty: Look for systems that offer a comprehensive warranty to protect your investment.
  2. Hybrid Systems: Hybrid systems combine the benefits of both electric and gas heating, providing optimal efficiency and comfort.
  3. Hyper Heat: Hyper heat systems are designed to provide reliable heating even in extreme cold temperatures.
  4. Rebate Available: Some low NOx systems may be eligible for rebates or incentives from local utility companies or government programs.
  5. Two-State Condenser: Two-state condenser systems offer superior energy efficiency and comfort by providing two levels of cooling or heating power.
  6. Variable Speed Condenser: Variable speed condenser systems are designed to adapt to the specific cooling or heating needs of your home, resulting in improved energy efficiency and comfort.


Q: Are low NOx systems more expensive?

A: Low NOx systems can vary in cost depending on the specific features and brand. However, it’s important to consider the long-term benefits and potential energy savings when comparing prices.

Q: Will a low NOx system require more maintenance?

A: Low NOx systems do not typically require more maintenance than traditional systems. However, regular maintenance is still important to ensure optimal performance and efficiency.

Q: Can I retrofit my existing system to reduce NOx emissions?

A: In some cases, it may be possible to retrofit your existing system with components or features that help to reduce NOx emissions. However, it’s best to consult with a professional HVAC technician to determine the feasibility and cost of retrofitting.

Q: Are low NOx systems more energy-efficient?

A: Low NOx systems are designed to be more efficient at burning fuel, which can result in improved energy efficiency. However, the overall energy efficiency of a system will depend on factors such as the specific model, installation, and usage.


Low NOx AC and furnace systems offer a range of benefits, including reduced environmental impact, improved air quality, and regulatory compliance. When choosing a low NOx system, it’s important to consider the specific features and options that best meet your needs. With advanced combustion technology and design features, low NOx systems help to minimize nitrogen oxide emissions and contribute to a cleaner and healthier environment.
