Factors to Consider When Purchasing a New Gas Furnace

In today’s fast-paced world, where comfort and efficiency are paramount, choosing the right gas furnace for your home is a crucial decision. ROX Heating & Air understands the importance of this choice, and we’re here to guide you through the factors you need to consider when purchasing a new gas furnace.

Understanding Your Heating Needs

Before delving into the technical details of gas furnaces, it’s essential to assess your heating needs. Every home is unique, and your heating requirements may differ significantly from your neighbors. Factors such as the size of your home, climate, insulation, and personal preferences play a vital role in determining the right furnace for you.

Key Considerations:

1. Furnace Efficiency

The efficiency of a gas furnace is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. Higher AFUE ratings indicate greater energy efficiency, which can lead to reduced energy bills. It’s essential to strike a balance between efficiency and cost when selecting a furnace.

2. Heating Capacity

Ensure that the furnace you choose has the heating capacity to meet your home’s needs. An undersized furnace will struggle to keep your home warm, while an oversized one can lead to unnecessary energy consumption and discomfort.

3. Fuel Source

Gas furnaces are popular for their efficiency and affordability. However, you should also consider alternative fuel sources, such as electric or dual-fuel systems, depending on your location and energy availability.

Choosing the Right Model

Once you have a clear understanding of your heating needs, it’s time to explore the various gas furnace models available in the market. ROX Heating & Air offers a wide range of options to suit your requirements.

Key Considerations:

1. Single-Stage vs. Two-Stage vs. Modulating Furnaces

Gas furnaces come in different types, including single-stage, two-stage, and modulating models. Single-stage furnaces operate at full capacity when turned on, while two-stage and modulating furnaces offer more precise temperature control and energy savings.

2. Brand Reputation and Warranty

Choosing a reputable brand is crucial when investing in a gas furnace. Look for manufacturers with a history of reliability and excellent customer support. Additionally, check the warranty terms to ensure your investment is protected.

3. Noise Levels

Consider the noise levels of the furnace, especially if it will be installed near living spaces. Modern furnaces are designed to operate quietly, but it’s still essential to verify the decibel levels.

Installation and Maintenance

The installation and maintenance of your gas furnace are as important as the unit itself. Proper installation and regular upkeep ensure the longevity and efficiency of your heating system.

Key Considerations:

1. Professional Installation

Always opt for professional installation to ensure that your furnace operates safely and efficiently. DIY installation can lead to costly mistakes and potential safety hazards.

2. Regular Maintenance

Scheduled maintenance by qualified technicians is essential to keep your gas furnace in optimal condition. This includes cleaning, inspecting, and replacing components as needed.

3. Air Quality

Consider installing air quality accessories, such as air purifiers and humidifiers, to enhance the comfort and health of your indoor environment.

Energy Efficiency and Savings

Investing in an energy-efficient gas furnace not only benefits the environment but also your wallet. ROX Heating & Air is committed to helping you make eco-friendly choices without compromising on comfort.

Key Considerations:

1. Energy Star Certification

Look for gas furnaces that have earned the Energy Star certification. These models meet strict efficiency standards set by the Environmental Protection Agency (EPA) and can significantly reduce your energy consumption.

2. Programmable Thermostats

Pair your gas furnace with a programmable thermostat to optimize heating schedules and save on energy costs. This allows you to heat your home only when necessary, reducing waste.

3. Tax Credits and Rebates

Explore potential tax credits and rebates available for energy-efficient heating systems in your area. These incentives can make upgrading to a high-efficiency furnace even more financially appealing.


In conclusion, choosing the right gas furnace for your home involves a thoughtful assessment of your heating needs, selecting the appropriate model, ensuring professional installation and maintenance, and considering energy-efficient options.
