Furnace Repair in Greenville, SC

Most furnace repairs cost between $150 and $1,500, depending on what is actually wrong with the system and which parts need to be replaced.

If your system requires a simple fix like replacing a thermocouple, cleaning a flame sensor, or swapping out an ignition switch, you can expect to pay somewhere in the $150 to $300 range. If the problem is more involved and requires replacing a blower motor, control board, or inducer motor, the cost typically runs between $400 and $900. Major repairs involving the heat exchanger can cost more than that, though at that point replacement often makes more financial sense than continuing to invest in an aging system.

We charge a diagnostic fee to come out and identify the problem, and that fee gets applied to the repair cost if you decide to move forward with the work. You will know exactly what the repair will cost before we start, and that price will not change once we begin.

Yes, we offer financing options on repairs so an unexpected breakdown does not force you to choose between fixing your furnace and covering your other expenses.

If your repair bill is higher than you were expecting or if the timing is just bad, financing lets you get the work done now and pay it off over time in manageable monthly payments. This is especially helpful for mid-range repairs like replacing a blower motor or control board, where the cost is significant but the repair makes more sense than replacing the entire system.

We can walk you through your financing options when we provide the repair estimate so you know exactly what your choices are before making a decision.

Yes, we offer same-day service for most calls. A broken furnace in the middle of winter is not something that can wait, and we understand that you need your heat back on as quickly as possible.

Our technicians keep their trucks stocked with common replacement parts, which means many repairs can be completed in a single visit without having to order parts and schedule a return trip. If we do need to order something specific to your system, we will let you know upfront and get you scheduled as soon as the part arrives so you are not left waiting any longer than necessary.

When you call, we will give you a service window and keep you updated if anything changes. Our goal is to get a technician to your home quickly, diagnose the problem accurately, and get your system running again the same day you call.

Most furnace repairs take between one and two hours once the technician arrives and begins working on the system. The exact time depends on what is wrong and how accessible the furnace is in your home.

If the problem is straightforward and requires replacing a common part like a thermocouple, flame sensor, or ignition switch, the repair will typically be on the shorter end of that range. If the issue is more complex and involves replacing a blower motor, control board, or inducer motor, the work will take longer because those components require more time to remove and install properly.

In some cases we may need to order a part that is specific to your furnace model. If that happens, we will let you know before we leave and schedule a follow-up visit as soon as the part comes in. We will not leave you guessing about the timeline or when to expect us back.

A furnace that runs but only blows cold air is one of the most common problems we get calls about, and there are a few different things that could be causing it.

The most common culprit is a dirty air filter. When the filter gets clogged with dust and debris, it restricts airflow and causes the furnace to overheat. Most furnaces have a safety switch that shuts the burners off when this happens, which means the blower keeps running but the system stops producing heat. Checking and replacing your air filter is the first thing you should do before calling for service.

If the filter is clean and the problem persists, the issue is likely related to the ignition system or flame sensor. A malfunctioning flame sensor will shut down the burners as a safety precaution even though there is nothing actually wrong with the combustion process. A faulty ignition switch or pilot light problem will prevent the burners from lighting in the first place. In either case, the blower will continue circulating air while the system fails to produce any heat.

Less commonly, the issue could be related to your gas supply or a problem with the thermostat settings. We will diagnose exactly what is happening and get warm air flowing again.

Furnaces are not silent machines, but they should not be loud or disruptive when they run. If you are hearing sounds that were not there before or noises that seem to be getting louder over time, something is likely wearing out or coming loose inside the unit.

Banging or popping sounds when the furnace kicks on often indicate delayed ignition. This happens when gas builds up in the combustion chamber before finally lighting, and the small explosion you hear is that gas igniting all at once. Delayed ignition puts stress on the heat exchanger and should be addressed before it causes more serious damage.

Squealing or screeching sounds usually point to a problem with the blower motor or the belt that drives it. The motor bearings may be wearing out and need lubrication, or the belt itself may be frayed and slipping. These are relatively inexpensive repairs if caught early, but ignoring them can lead to a complete blower failure that costs significantly more to fix.

Rattling sounds can come from a few different sources. Loose panels on the furnace cabinet, unsecured ductwork, or components inside the unit that have vibrated themselves free over time can all produce rattling noises. While rattling is not always urgent, it is worth having a technician take a look to make sure nothing is coming loose in a way that could cause bigger problems down the road.

If you are hearing any of these sounds, give us a call at (864) 295-0905 and we will figure out what is going on.

A furnace that will not respond at all can be frustrating, but the cause is often something simple that you can check yourself before calling for service.

Start by looking at your thermostat to make sure it is set to heat mode and the temperature is set higher than the current room temperature. If your thermostat runs on batteries, try replacing them because a dead battery can make it look like the furnace has stopped working entirely when the system itself is actually fine.

If the thermostat checks out, take a look at your circuit breaker panel to see if the breaker for your furnace has tripped. A tripped breaker is one of the most common reasons a furnace appears completely dead, and flipping it back on may be all you need to restore normal operation. If the breaker trips again immediately after you reset it, there is an electrical issue that needs professional attention and you should leave it off until a technician can take a look.

If the thermostat is working and the breaker has not tripped, the problem is likely something internal to the furnace itself. A faulty ignition system, a broken blower motor, or a safety switch that has shut the system down to prevent damage are all possibilities at that point. Our technicians will work through the issue systematically to find the root cause and get your heat back on as quickly as possible.

The answer depends on the age of your system, the cost of the repair, and how often you have been calling for service over the past few years.

If your furnace is under 15 years old and has been regularly maintained, repairing it almost always makes more financial sense than replacing it. A single repair does not mean the system is on its way out, and a well-maintained furnace can run reliably for 20 years or longer. Spending a few hundred dollars to fix a specific problem is a reasonable investment if the rest of the system is in good working condition.

The calculation starts to shift when you are dealing with an older furnace or when repairs are becoming a regular occurrence. If your system is over 15 years old and the repair bill is more than a few hundred dollars, you should at least consider whether that money would be better spent toward a new unit. The same is true if you have been calling for service multiple times a year, because those repair costs add up quickly and you are essentially paying to keep an aging and increasingly inefficient system running.

A good rule of thumb is to compare the repair cost to about half the price of a new furnace. If the repair exceeds that threshold and the system is past the 15 year mark, replacement is usually the smarter long-term investment. If the repair falls well below that number, fixing the existing system makes more sense.

We will give you an honest recommendation based on what we find when we inspect your furnace, even if that means telling you a simple repair is all you need right now.

It depends on the specific repair and the overall condition of the system, and the answer is not always as straightforward as you might expect.

Minor repairs are usually worth doing even on an older furnace. If your system needs a new thermocouple, ignition switch, or blower belt, those fixes typically cost between $150 and $300 and can add several more years of reliable operation to the unit. There is no reason to replace an entire furnace over a $200 repair, even if the system is 18 or 20 years old.

The decision gets more complicated when you are facing a major repair on an aging system. Replacing a blower motor or control board on a 20-year-old furnace might cost $600 to $900, and at that price you are putting significant money into equipment that could develop another problem within a year or two. Replacing a heat exchanger is even more expensive and rarely makes sense on a furnace that is past its expected lifespan, because the labor and parts cost often approaches what you would pay for a new system entirely.

The overall condition of the furnace matters as well. If the unit has been well maintained over the years, runs efficiently, and this is the first major issue it has had, a repair may still be worthwhile. If the furnace has a history of problems and you have already spent money on multiple repairs in recent years, those costs compound and the math starts to favor replacement.

We will look at the full picture and give you an honest recommendation based on what makes the most financial sense for your situation.
