How You Can Benefit from a New Furnace

A new electric or gas furnace will benefit you in numerous ways. New and improved furnace models that aim to increase comfort and the user’s experience while simultaneously reducing energy use are coming out every year.

Wonder why so many of our customers love their new furnaces? Investing in a new high-efficiency unit has its fair share of advantages, including…

  • Improvements in indoor air quality
  • Reductions in annual operating costs
  • Better energy efficiency ratings
  • Consistently heated air without hot or cold spots
  • Lower heater repair and utility expenses
  • Heightened comfort control accessibility with connective devices
  • Energy-efficiency tax credit that can offset furnace cost(s)

Different Types of Furnaces

There are numerous types of furnaces available in the market today, with the most common being gas and electric furnaces.

Gas Furnaces

We specialize in natural gas furnaces here at Top Flight. These systems are connected to your gas lines and utilize natural gas as fuel, delivering not only reliable and efficient heating but also a remarkable level of comfort. They are perfect for areas where natural gas is easily available. Modern gas furnace units are designed with advanced technology to deliver maximum heat output with minimum energy usage, effectively lowering your monthly energy costs.

Electric Furnace

If you’re considering a more environmentally-friendly option or if your property lacks access to a gas line, an electric unit could be a viable choice. These systems embody the principles of energy-efficient heating systems. While their operating expenses may exceed gas furnace costs, they offset this with quieter operation, enhanced durability, tax credit opportunities, and lower installation costs. Speak to our crew today if you’re interested in one of the many high-efficiency models available!

Oil Furnace

Heating oil furnace units are even older than natural gas furnaces. An oil furnace is a fixture you don’t see often anymore, but some older homes in especially cold climates still utilize them for warmth. Since this type of furnace depends on regular heating oil delivery, these older units are less favorable compared to today’s high-efficiency furnaces. Nevertheless, we can still help with these types of residential furnaces, whether you need your unit repaired or you’re interested in old furnace removal.

The Importance of Proper Furnace Maintenance

At Top Flight Heating & Air, we offer comprehensive maintenance services to keep your furnace in top condition. Just like any other HVAC system in your home, maintaining your furnace is crucial to ensure its optimal performance. A well-functioning furnace not only improves your comfort but also helps in reducing energy costs, which will allow you to save money over time. Regular maintenance of your furnace includes tasks like inspecting the heat exchanger for cracks, cleaning the burners, checking for gas leaks in gas furnaces, and checking all electrical connections in electric furnaces.

Here’s why regular furnace maintenance is so crucial:

Prolonged Lifespan

Furnaces, whether gas or electric, aren’t minor investments. Regular maintenance helps ensure your furnace runs efficiently for as long as possible. By replacing worn-out parts and addressing minor issues before they become significant problems, you can effectively extend the lifespan of your HVAC system and avoid premature new furnace installation costs.

Reduced Energy Bills

An inefficient furnace needs to work harder to provide the same amount of heat, using more energy in the process. With proper maintenance, your furnace will operate at peak efficiency, saving you money on energy bills. Regularly replacing your furnace’s air filters, for example, can significantly improve its efficiency and lower your heating costs.

Prevent Unexpected Breakdowns

There’s nothing worse than having your furnace break down in the middle of a cold winter night. Regular maintenance from a qualified HVAC contractor can help identify potential issues and fix them before they lead to a system failure.

Improve Indoor Air Quality

Your furnace filter traps dust, allergens, and other airborne particles, improving the air quality in your home. If these filters aren’t regularly cleaned or replaced, they can become clogged, reducing their effectiveness and leading to poor indoor air quality.


Gas furnaces, in particular, need to be properly maintained to ensure safety. A damaged or malfunctioning natural gas furnace can potentially leak carbon monoxide, a dangerous, odorless gas. Regular maintenance ensures all components are in good condition, preventing any potential safety risks that can arise from your natural gas furnace.

Why Do I Need a Professional HVAC Technician to Install a Furnace?

Whether it’s a gas furnace install or an electric furnace setup, hiring a professional HVAC technician is imperative. Our team at Top Flight Heating & Air is well-versed in all safety standards and codes. They ensure proper gas line connections, ductwork installation, and testing of the system to ensure it’s working correctly.

A professionally installed furnace promises high performance, safety, and efficiency, which all contribute to your overall savings on heating costs.

What Is the Electric and Gas Furnace Installation Process?

Having a new furnace installed may seem like an overwhelming task, but with the right heating and air conditioner experts by your side, it becomes a seamless endeavor. Let’s take a detailed look at the installation process!

Step 1: Initial Assessment and Furnace Selection

The first step of any new furnace install involves a comprehensive assessment of your home and your heating needs. Our skilled HVAC contractors take into account factors such as your home’s size, existing insulation, your local climate, and the current state of your ductwork system. This critical assessment helps us determine the right type and furnace size you’ll need, be it a gas furnace, an oil furnace, or an electric furnace.

Step 2: Removal of the Old Furnace

After the assessment, we proceed to the furnace removal stage. Our technicians ensure that your old furnace system is safely disconnected from its power source, whether that’s natural gas or electricity, and carefully detached from the existing air ducts. If you are having a gas furnace installed, we will work with your utility company to ensure that your gas lines are handled properly.

Step 3: Preparing for the New Installation

Once your old furnace has been removed, the next step in the installation process is preparing your home for the new furnace. This could include the inspection and potential repair or replacement of the existing ductwork, checking for hot and cold spots to ensure optimal airflow, or potentially installing new gas lines for a gas furnace installation.

Step 4: Installation of the New Furnace

The heart of the process, installing the new furnace, requires professional expertise. Whether we are dealing with electric furnaces, gas furnaces, or oil furnaces, our technicians will connect your new furnace unit to the necessary power sources and ductwork, ensuring that every component is installed correctly for optimal operation. We will also take care to connect your unit to your electrical system responsibly without causing problems for your other electrical appliances.

Step 5: Testing and Final Adjustments

After the furnace installation is complete, our team will test your new furnace, making any necessary final adjustments. This includes checking for any gas input issues with gas furnaces, making sure your air conditioner is working harmoniously with your new heating system, and ensuring your home is free of carbon monoxide.

Post-Installation Support

At Top Flight Heating & Air, our job doesn’t end after we install a furnace in your home. We are committed to ensuring that your heating system works optimally. That’s why we provide you with vital information about proper maintenance for your new furnace, as well as tips to help you save money on your monthly energy costs.

Why Do I Need a Custom Estimate for Furnace Replacement and Installation?

If you’re like most homeowners, the first thing you think of regarding replacing or installing a new furnace is, “How much will my new furnace cost?” We wish there was a simple answer to give you about the average installation cost for the furnace of your choice, but the truth is that every home and business is unique, so no two installation cost estimates are the same.

What goes into your unit’s installation cost? Some of the factors we need to know to provide an accurate furnace cost estimate include:

  • Whether you are installing in a new home or need a replacement furnace
  • The new furnace cost you are able to pay (your budget)
  • The size of your home or business to help us determine the necessary airflow capacities
  • Whether ventilation is already in place, requires installation, or needs replacement
  • The type of energy source that is available to you (gas, electric, oil)
  • The amount of fuel consumed during a typical heating season
  • Parts and labor costs
