Furnace Replacement

Why Does Choosing the Right Furnace Matter?

Selecting the appropriate furnace for your home is crucial for several reasons. First, proper sizing ensures optimal performance and energy efficiency, preventing issues like uneven heating or excessive energy consumption.

Beyond size, factors such as fuel type, efficiency ratings, and advanced features play vital roles in determining the furnace’s safety, effectiveness, and long-term cost savings. With modern high-efficiency systems, you can save up to 50% on heating bills compared to decade-old heaters. 

Investing in the right furnace enhances indoor comfort, reduces energy bills, and ensures safer heating for years to come.

How Can I Choose the Right Furnace Model?

Our furnace installation services are designed to help you find the perfect unit for your home, and our HVAC technicians always offer honest and unbiased advice. We offer a broad range of models and a complimentary consultation with our experts before you make a purchase, so you can feel confident that your new heating installation will meet your needs.

Factors that Can Guide you in Selecting the Correct Model for your Home:

Your climate

Consider your local climate when selecting a furnace model. You might be surprised that climate can vary within the same county, and even from house to house.  A great way to determine annual temperature fluctuations is to find out your local plant hardiness zone. Also, consider your landscape. A home surrounded by pine trees will be colder in winter than one bathed in sunlight.

Fuel formats available to your home and suitable for your heating needs

Evaluate the fuel options accessible for your home, such as natural gas, propane, or electric, and choose the one that aligns with your heating needs and budget.

To determine available fuel formats, consult local utility providers, fuel suppliers, government resources, building codes, or HVAC professionals like Exxel.

The average monthly cost of operation

Calculate the anticipated monthly operating costs for different furnace models based on their efficiency ratings and fuel prices to determine the most reasonable, cost-effective option.

Energy efficiency goals

Want to save money and help the environment? Set energy efficiency goals for your home and choose a furnace model with high Annual Fuel Utilization Efficiency (AFUE) ratings to meet these objectives and reduce energy consumption.

Size of the unit compared to the size of your home

Ensure the furnace’s size matches your home’s heating requirements by considering factors like square footage, insulation levels, and ceiling height to achieve optimal comfort and efficiency.

HVAC accessories compatible with your furnace

Explore compatible HVAC accessories like a programmable thermostat, zoning systems, or air purifiers that can enhance comfort and energy efficiency when paired with your chosen furnace model.
