Furnaces are a popular choice among South Carolina residents thanks to their efficiency and ability to provide consistent warmth during the cooler months. These heating systems excel in distributing heat evenly throughout your space, helping your home remain comfortable regardless of the outdoor temperature. With advancements in technology, modern furnaces also offer enhanced energy efficiency, which can lead to lower utility bills and a reduced carbon footprint. Investing in a quality furnace allows you to enjoy reliable heating while enjoying the peace of mind that comes with an energy-efficient system.

Our friendly and knowledgeable team is dedicated to helping you select the perfect furnace for your home, whether you need installation, repair, or maintenance services. With our commitment to quality workmanship and customer satisfaction, you can trust us to keep your furnace running smoothly and your home warm and inviting all winter long.

Do You Need a Furnace if You Have Central Air?

While having central air conditioning provides cooling during the hotter months, it doesn’t necessarily eliminate the need for a furnace in colder climates. Central air systems are designed to cool and circulate air but do not generate heat. Therefore, if you live in an area that experiences cold winters, a furnace is essential to maintain a comfortable indoor environment during those chilly months. Without it, you may find your home uncomfortably cold, and relying solely on supplementary heating sources could lead to inefficiencies and higher energy costs.

Additionally, many homes benefit from a dual system where a furnace works harmoniously with central air conditioning. This setup allows homeowners to enjoy the advantages of both heating and cooling without compromising comfort.

Investing in a reliable furnace ensures that your home stays warm and cozy when temperatures drop while your central air system handles the heat during summer. Ultimately, having both systems in place can offer greater flexibility and energy efficiency.

The Average Lifespan of a Furnace

On average, most well-maintained furnaces will last between 15 and 20 years. However, several factors can significantly impact how long your furnace remains in optimal condition.

Your furnace’s lifespan can be influenced by: 

  • Fuel type: Oil-fueled furnaces generally have a longer lifespan compared to gas or electric models.
  • Size: A furnace that is too large will cycle on and off frequently, causing added wear and tear, while one that is too small may run constantly, which can also diminish its longevity.
  • Ductwork quality: Poorly installed or improperly sized ductwork, especially with excessive leaks, increases the workload on your furnace, directly affecting its lifespan.
  • Thermostat settings: Setting the thermostat to inappropriate temperatures can overwork the system. Ideally, maintain settings between 60°F and 80°F to reduce strain.
  • Maintenance: Regular maintenance is crucial. A well-maintained furnace is more likely to reach its full lifespan and may even exceed it.

Keeping these factors in mind and investing in proper care can help your furnace serve you well for many years.

How Often Should Your Furnace Be Serviced?

It is generally recommended that you schedule maintenance for your furnace at least once a year, typically before the colder months arrive. This annual check-up allows one of our qualified technicians to inspect various components, clean necessary parts, and replace filters as needed. By maintaining your furnace proactively, you can prevent common issues and minimize the risk of unexpected breakdowns during the winter.

Aside from routine servicing, being aware of specific signs that your furnace may be malfunctioning is equally important. If you notice any unusual noises, such as banging or whistling, inconsistent heating throughout your home, or an increase in your energy bills without any changes in usage, these could indicate an underlying problem. Additionally, if your furnace frequently cycles on and off or emits a strange smell, it’s time to consult a professional. Addressing these warning signs early can save you from high repair or replacement costs.

What would cause my Furnace to stop working?

There are a number of things that may cause your heating system to stop working. The most common issues we see from furnaces that result in repairs in the area include:

  • Broken Thermostat – If your thermostat runs out of batteries or stops working altogether, it can’t tell your furnace to operate.
  • Blocked Air Flow – If there is furniture or something obstructing the return air vent in your home, it can cause problems for your system and eventually cause it to stop working.
  • Burners Need To Be Replaced – Over time, burners collect dirt and dust, which can hinder heat output from the system.
  • Broken Igniter – When the furnace igniter is not working, heat cannot be generated to warm your home.

Just had my bi-yearly HVAC checkup by Justin from RS Andrews. I found him to be a very polite, honest and informed technician. I have a system that is getting older so seasonal maintenance is very important to me and my wallet. He advised me of potential problems going forward (not to say that these problems will actually happen), fixed a small gas leak in my furnace and performed proper maintenance procedures on my system to help insure that I will have a comfortable summer. I am a happy camper.
