Choosing Furnaces and Coil Systems

Table of Contents


When it comes to choosing the right furnace and coil systems for your home, there are several important factors to consider. The heating and cooling system in your home plays a vital role in maintaining a comfortable indoor environment, so it’s essential to choose the right equipment to ensure efficiency and performance. In this blog post, we will discuss the key factors to consider when choosing furnaces and coil systems, and provide some useful tips to help you make an informed decision.

1. Types of Furnaces

There are several types of furnaces available in the market, and each has its own advantages and disadvantages. Here are some common types of furnaces to consider:

  • Gas Furnaces: Gas furnaces are the most common type of furnace used in residential homes. They use natural gas or propane as fuel to heat the air and distribute it through the ductwork. Gas furnaces are known for their high efficiency and lower operational costs compared to other types of furnaces.
  • Electric Furnaces: Electric furnaces use electricity to generate heat. They are typically more expensive to operate compared to gas furnaces, but they have a lower upfront cost and are easier to install. Electric furnaces are a good option for homes without access to natural gas or propane.
  • Oil Furnaces: Oil furnaces use heating oil to generate heat. They are less common than gas or electric furnaces but are still used in some areas. Oil furnaces require a storage tank for the oil and regular maintenance to ensure proper operation.
  • Dual-Fuel Furnaces: Dual-fuel furnaces combine the benefits of a gas furnace with an electric heat pump. They can switch between gas and electric heating based on the outside temperature, providing efficient operation all year round.

2. Energy Efficiency

Energy efficiency is an important consideration when choosing furnaces and coil systems. Look for equipment that has a high Annual Fuel Utilization Efficiency (AFUE) rating. AFUE measures the amount of heat produced by the furnace compared to the amount of fuel consumed. The higher the AFUE rating, the more efficient the furnace is. Consider investing in furnaces with AFUE ratings of 90% or higher to maximize energy savings and reduce utility bills.

3. Size and Capacity

Choosing the right size and capacity for your furnace is crucial for efficient heating. A furnace that is too small will struggle to heat your home, while an oversized furnace will cycle on and off frequently, wasting energy. Consult with a heating professional to determine the appropriate size and capacity for your home based on factors such as square footage, insulation, and climate.

4. Compatibility with Coil Systems

Coil systems, also known as evaporator coils, work in conjunction with your furnace to provide cooling during the summer months. When choosing a furnace, it’s important to ensure compatibility with your existing coil system or choose a matching coil system if you are replacing both components. Matching the furnace and coil system ensures optimal performance and efficiency.

5. Maintenance and Warranty

Regular maintenance is essential to keep your furnace and coil system running smoothly and efficiently. Some manufacturers offer extended warranties and maintenance plans, which can help protect your investment and provide peace of mind. Be sure to inquire about the warranty and maintenance options when purchasing your equipment.

6. Professional Installation

Proper installation of your furnace and coil system is crucial for optimal performance and reliability. Hiring a professional HVAC contractor ensures that the equipment is installed correctly and according to manufacturer specifications. Professional installation also ensures compliance with local building codes and safety standards.


Choosing the right furnace and coil systems for your home is a significant decision that requires careful consideration. By evaluating the types of furnaces available, considering energy efficiency, sizing and compatibility, maintenance and warranty options, and hiring a professional for installation, you can ensure a comfortable and efficient heating and cooling system for your home. Consult with a heating professional to guide you through the selection process and make an informed decision that meets your specific needs.
