Signs You Need Furnace Repair

Most furnace heating systems are dependable until they start to break down. At that point, their reliability becomes questionable. Here are some scenarios you may encounter when you’re in need of furnace repair services from a heating and air conditioning contractor.

Uneven Heating

When your furnace is not able to heat your entire home, there is a problem. It could be any of a number of issues, from a broken blower motor to air ducts that have been damaged.

Short Cycling

Short cycling can damage your furnace quickly. Short cycling occurs when the HVAC unit turns on, shuts off a short time later, and starts the cycle again in a few minutes. The rapid turning on and off of the unit causes major wear and tear on the moving parts of your HVAC system.

Unusual Noises

Aside from the sound of your furnace starting or stopping a cycle, they are generally pretty quiet. If any other sounds beyond the general hum of the heating system occur, call for furnace repair services. This includes banging, squealing, rumbling, and other odd noises.

HVAC System Runs Constantly

When the system runs constantly, it is generating excess energy waste and overheating the house. A heating services call is an easy way to isolate the problem and get the unit back to working order.

Thermostat Not Working

Your thermostat is the little gauge that tells the furnace to start or stop. When it is not working, neither is the furnace. If you’re having trouble with your thermostat, contact our HVAC technicians for HVAC services.

How to Tell If Your Furnace Needs Emergency Repair

In many situations, furnace malfunctions can be handled in a timely manner with a service call during business hours. However, some furnace issues arise unexpectedly and can pose serious risks if not addressed promptly. Here are the urgent situations where your furnace requires immediate repair:

No Heat

If your furnace suddenly stops producing heat, especially in the middle of a cold night, this is a critical issue. A complete loss of heat can quickly lead to dangerously low temperatures inside your home, making it essential to get emergency repairs as soon as possible.

Gas Leaks

The smell of gas near your furnace is an emergency situation that requires immediate attention. Gas leaks are hazardous and can lead to carbon monoxide poisoning or even explosions. If you detect a gas odor, evacuate your home and contact emergency services and a furnace repair technician right away.

Carbon Monoxide Alarm

If your carbon monoxide detector goes off, it’s a serious warning that your furnace might be leaking this dangerous, odorless gas. Carbon monoxide exposure can be life-threatening, so it’s critical to turn off your furnace, ventilate your home, and seek emergency furnace repair services immediately.

Electrical Issues

Flickering lights, tripped breakers, or burning smells from your furnace are all signs of electrical problems. These issues can quickly escalate to fires or complete system failures, making immediate repair essential to ensure your safety.

Furnace problems rarely occur at convenient times—they often happen in the middle of the night, during a weekend, or on a holiday when you need heat the most. That’s why at Ravinia Plumbing, we offer 24/7 emergency furnace repairs in Buffalo Grove, IL. Our expert technicians are always on call to address urgent situations, and we make them a top priority.

Don’t wait—contact us immediately if you’re experiencing any of these critical furnace problems.

Should I Repair or Replace My Furnace?

Whether you should repair your current system or look into new furnace installation is a tough question. You don’t want to replace it too soon and lose any life that it may still have. You also don’t want to put off furnace installation to the point where it becomes unreliable and costly. Below are some situations where it may be better to go with a new furnace or repair your heating system.

It’s better to repair your furnace when…

The furnace repair cost is small or when the unit is still under warranty. It is also a good indication that there is plenty of life left in the system if this is one of its first breakdowns. So, if the unit has been very reliable, repair it. Also, if the unit is not that old, the repair is relatively minor, and the repair costs are affordable, we recommend having the system repaired.

It’s better to replace your furnace when…

It’s over 10 years old and it begins to break down more often. As HVAC systems become less reliable, they should be replaced. If there is a poor history of maintenance and the system is beginning to break down, it’s better to have a new HVAC system installed. Putting your hard-earned money toward the purchase of a new system instead of frequent repairs is a smart investment.

Frequently Asked Questions About Furnace Repair

What is the most expensive repair on a furnace?

The most expensive furnace repair is often replacing the heat exchanger. This component is essential for safely transferring heat into your home, and if it cracks, it can pose serious safety risks. Because it’s a major part that requires significant labor to replace, costs can be high. In some cases, replacing the entire furnace may be more cost-effective than repairing it.

One of the most common furnace repair issues is a faulty ignitor or flame sensor. These parts are responsible for starting and regulating the heating process. When they fail, your furnace may blow cold air or fail to turn on altogether. Other common problems include dirty filters, worn belts, and malfunctioning thermostats.

When they fail, your furnace may blow cold air or fail to turn on altogether. Other common problems include dirty filters, worn belts, and malfunctioning thermostats.

Standard homeowners insurance usually doesn’t cover furnace repairs or replacement due to normal wear and tear. However, damage caused by a covered event—such as a fire or flooding—may be included. Some homeowners invest in home warranty plans that cover furnace repair and replacement, which can help reduce unexpected costs.

 

If your furnace stops working during freezing weather in Buffalo Grove, Lake County, or Cook County, it can absolutely be considered an emergency. Not only does it make your home uncomfortable, but prolonged exposure to extreme cold can be dangerous for your family, pets, and plumbing. We offer prompt furnace repair to restore your heat quickly and safely.

A furnace that requires repair often exhibits clear signs like unusual noises, inconsistent heating, or frequent cycling on and off. If your furnace is not heating your home as it should, is making strange sounds, or has a sudden increase in energy usage, it likely needs a repair.

A tune up, on the other hand, is a preventative maintenance service meant to keep your furnace running efficiently and to catch small issues before they become big problems. If you’re unsure, it’s best to have a professional inspect your furnace to determine the appropriate action.

If your furnace stops working unexpectedly, the first step is to check your thermostat settings, power supply, and the circuit breaker to ensure everything is in order. If your furnace uses a pilot light, make sure it’s lit. If everything seems fine and your furnace still isn’t working, it’s time to call for emergency repair service. At Ravinia Plumbing, we offer 24/7 emergency furnace repair in Buffalo Grove, IL, so you can restore heat to your home as quickly as possible, regardless of the time.

It’s recommended to replace your furnace filter every 1 to 3 months, depending on the type of filter and your household’s needs. Homes with pets, smokers, or people with allergies may require more frequent filter changes. A clean filter ensures that your furnace operates efficiently and prevents dust and debris from damaging the system. Regular filter replacement is a simple and cost-effective way to avoid more significant furnace issues and save money on repairs.

Furnace repair should always be performed by a licensed professional. Furnaces involve complex components, including gas lines and electrical systems, that can be dangerous if handled improperly. DIY repairs not only pose safety risks but could also void your furnace’s warranty and lead to more expensive issues down the line. For your safety and peace of mind, always rely on a qualified technician for furnace repairs.

A cracked heat exchanger can be extremely dangerous because it can allow carbon monoxide, a colorless and odorless gas, to leak into your home. Signs of a cracked heat exchanger include a yellow flame instead of blue, soot buildup inside the furnace, and a strange odor similar to formaldehyde. If you suspect a cracked heat exchanger, turn off your furnace immediately and call a professional for an inspection and repair. Carbon monoxide poisoning is life-threatening, so this issue should never be ignored.

The time required to repair a furnace varies depending on the problem at hand. Minor repairs, like replacing a thermostat or fixing a small electrical issue, might take just an hour or two. More complex issues, such as replacing a motor or fixing a gas leak, can take several hours. During an initial inspection, your technician should be able to provide a more accurate estimate of the repair time based on the specific issue.

Regular furnace maintenance is key to preventing unexpected furnace repairs. Scheduling annual tune ups, regularly changing air filters, and addressing small issues as soon as they arise can extend the life of your furnace and prevent costly breakdowns. Keeping the area around your furnace clean and ensuring that your vents are not blocked also helps maintain efficient operation.
