Furnace Installation & Replacement in Greenville, SC

Most homeowners in Greenville pay between $3,500 and $8,000 for a new furnace installation. That range depends on a few things, starting with the type of furnace you choose. Gas furnaces are the most common around here and tend to cost more upfront than electric models, but they’re significantly cheaper to run month over month.

Efficiency also plays a big role in pricing. A standard-efficiency furnace with an 80-89% AFUE rating will be easier on your wallet at purchase, while high-efficiency models rated 90% or higher can push the total cost above $10,000. The tradeoff is lower energy bills over time, which often makes up the difference within a few years.

Your home’s size matters too. Larger homes require more heating capacity, which means a bigger unit and a higher price tag. Installation complexity can also add to the cost if your ductwork needs modifications or your furnace sits in a hard-to-reach spot.

One advantage of living in Greenville is our relatively mild winters. You won’t need the same heating power as a home in Ohio or New York, which typically keeps costs toward the lower end of the national range.

Unusual noises could indicate issues such as loose parts or airflow obstructions. If you hear rattling, banging, or squealing, call us for a check-up.

Replacing both systems together can boost energy efficiency and ensure compatibility. It’s especially beneficial if both units are over 15 years old.

A gas furnace generates its own heat, ideal for colder climates. A heat pump transfers heat and can be more efficient in milder temperatures.

Furnace size is measured in BTUs (British Thermal Units), which indicates how much heat the unit can produce. A furnace that’s too small will struggle to keep up on cold days, while one that’s too big will cycle on and off frequently, wasting energy and wearing out components faster.

As a general rule, homes need about 30-40 BTUs per square foot in a climate like Greenville’s. A 2,000 square foot home would typically need a furnace in the 60,000-80,000 BTU range. But square footage is just the starting point.

Other factors play into proper sizing too. Ceiling height matters because you’re heating volume, not just floor space. Insulation quality affects how much heat your home retains. The number and age of your windows, which direction your home faces, and even how many people live there all influence the calculation.

Oversizing is a common mistake. Some contractors install bigger furnaces thinking it’s better, but it actually creates problems. Short cycling reduces efficiency, increases humidity issues, and shortens the lifespan of the equipment.

When we come out for an estimate, we assess your home’s specific needs rather than just eyeballing the square footage. That way you get a furnace that’s sized right and runs efficiently for years to come.

Most furnaces last between 10 and 15 years with proper maintenance. Some well-maintained units push past 15 years, though efficiency typically drops off significantly by that point.

A few factors influence how long your furnace will hold up. Regular maintenance is the biggest one. Annual tune-ups catch small problems before they become expensive repairs and keep the system running efficiently. Changing your air filter every one to three months also makes a noticeable difference in how hard the blower motor has to work.

The quality of the original installation matters too. A furnace that was properly sized and installed by qualified technicians will generally outlast one that was rushed or incorrectly set up. 

Once a furnace hits the 15-year mark, it’s worth keeping a closer eye on performance. Rising energy bills, frequent repairs, and uneven heating are all signs the system is nearing the end of its useful life. At some point, the cost of keeping an old furnace running exceeds what you’d pay for a new, more efficient unit.

If your furnace is getting up there in age and you’re not sure whether to repair or replace, give us a call at (864) 295-0905. We’ll give you an honest assessment.

A standard furnace installation typically takes between three and six hours. This means most jobs are completed in a single day. You won’t be left without heat overnight.

The actual timeline depends on a few variables. A straightforward swap where the new furnace is the same type and similar size to the old one goes faster. If we’re changing fuel types, modifying ductwork, or dealing with a tricky installation location like a cramped crawlspace or attic, the job takes longer.

We usually start the process by protecting your floors and work area, then disconnect and remove the old unit. The new furnace goes in, gets connected to your ductwork, gas line (if applicable), and electrical system. We test everything to make sure it’s running properly and walk you through the basics of your new system before we leave.

We also haul away the old furnace so you’re not stuck figuring out how to dispose of it yourself.

Our goal is to get you up and running with minimal disruption to your day. Most installations are finished by late afternoon, and you’ll have heat that same evening.

Yes. We understand that a new furnace is a significant investment, and not everyone wants to pay the full amount upfront. That’s why we offer flexible financing options to help make the cost more manageable.

Financing lets you spread the payments out over time, so you can get a high-quality, energy-efficient furnace now without draining your savings. In many cases, the monthly payment ends up being close to what you’re already losing in higher energy bills from an old, inefficient system. You upgrade your comfort and your home’s value without the financial strain.

We work with multiple lenders and can help you find a plan that fits your budget. Approval is typically fast, and we’ll walk you through your options during the estimate so you know exactly what to expect before making a decision.

If an unexpected breakdown forces your hand, financing means you don’t have to settle for the cheapest option or go without heat while you save up. You can get the right furnace for your home and pay it off on a timeline that works for you.

You can call us or ask about it when you schedule your free estimate to get more details about financing.
