Furnace Replacement & Installation Services

Services Providing Furnace Replacement Services Since 2007

Can you imagine facing winter without a functioning furnace? Unfortunately, if your system is more than a decade old, that scenario may become a reality. Like any essential appliance, heating systems have a lifespan. As years go by, breakdowns become more frequent, and finding replacement parts grows harder. Eventually, whether due to cost or necessity, every furnace reaches the point where replacement is the best option.

That moment rarely comes at a convenient time. It often happens late at night or during the coldest days of the year. Luckily, the experts at Gene May Heating & Cooling are ready to help. Regardless of your current fuel source, we’ll guide you through selecting a new furnace that fits your home and budget—and install it with the efficiency and care we’re known for.

Signs You Might Need a New Furnace

Furnaces rarely fail without warning. While some breakdowns are sudden, most systems send out warning signs before they stop working entirely. Some symptoms are obvious—like a system that won’t turn on—but others are more subtle. Watch for these common indicators that it may be time to consider a new furnace:

Age

If your furnace is over 10 years old, it may be nearing the end of its lifespan. At this stage, it’s often wise to weigh the benefits of replacement over repeated repairs. Newer models offer better efficiency and are often equipped with smart features that older systems lack. Plus, sourcing parts for aging equipment can become more difficult and expensive over time.

Repeated Service Calls

Have you needed more than one visit from a technician in a single heating season? When multiple components begin to fail in close succession, ongoing service fees can quickly exceed the cost of upgrading your system.

Persistent Odors

A lingering smell that doesn’t dissipate after the first few uses could signal a leak or ductwork issue. If the smell is only present during initial startup at the beginning of the season, it’s usually just dust burning off after months of inactivity—this is normal. If the odor continues, it’s best to call for professional inspection.

Unusual Noises

Rattling, banging, or other strange sounds coming from your furnace often point to mechanical trouble. These noises could indicate anything from a loose part to a failing motor. To determine the source, call a qualified heating repair expert.

Higher Energy Bills

When a furnace begins to fail, it often has to work harder to maintain your set temperature. This can result in a noticeable spike in your gas or electric bills. To see how much switching to a more efficient system could save, call (815) 828-5817 to schedule a quote for furnace replacement.

Rust or Corrosion

Some surface rust is normal with age, especially in the burner area. However, excessive rust—particularly near the heat exchanger—can signal a more serious issue and even pose a safety risk. It's always a good idea to have corrosion evaluated by an HVAC professional.

How to Ensure You Get the Best Furnace for Your Home

Once it’s determined that a new furnace is needed, our HVAC technicians will guide you through your options. This may include switching fuel sources, depending on your goals and home setup. We work to balance your comfort needs and budget with the following considerations:

Compatibility:

Switching from a traditional furnace to a heat pump or other system may require changes to your home’s ductwork.

Energy Efficiency:

New systems vary in AFUE (Annual Fuel Utilization Efficiency) ratings. If long-term savings are a priority, we’ll help you choose a unit with higher efficiency.

Sizing:

Too large of a furnace may short cycle; too small, and it will struggle to heat your space. Our team uses precise calculations to ensure you get the right fit.

An Ounce of Furnace Maintenance is Worth a Pound of Cure

Replacing your furnace is a major investment. Protect it with regular maintenance. We recommend seasonal service visits to ensure your equipment remains in peak condition. During each visit, our HVAC professionals check for:

• Loose wiring
• Dirty filters or internal components
• Carbon monoxide leaks
• Cracked or damaged fan blades
• Worn belts
• Excessive wear and tear
• Dirty burners

Scheduling this kind of routine furnace service will extend the life of your unit and improve performance. Learn more about our maintenance plans.

Frequently Asked Furnace Replacement Questions

What will it cost to replace my furnace?

The cost of installing a new furnace varies based on your home's size, desired energy efficiency, layout, and the brand you choose. Other factors include permit filing, any required ductwork changes, and labor. According to Forbes, the average cost of furnace replacement in 2024 is around $4,700. Air conditioners tend to be slightly less, while heat pumps can cost more.

How long will a new furnace last?

Most modern furnaces have an expected lifespan of 15 to 20 years when professionally installed and properly maintained. While some systems may last longer, that often comes at the cost of reduced efficiency and outdated technology. Regular maintenance is essential for getting the most out of your investment.

Can I replace my own furnace?

Although self-installation isn’t technically illegal in most areas, it’s strongly discouraged. You’ll need to pull permits, and some units may require a professional license for installation approval. Mistakes can lead to serious safety hazards like gas leaks, carbon monoxide poisoning, or fire. Most manufacturers also void warranties on units not installed by licensed professionals.

How do I know it’s time for a new furnace?

If you’re noticing frequent breakdowns, uneven heating, rising energy bills, or your system is over 10 years old, it might be time to upgrade. If you’re unsure whether it’s time to repair or replace, our HVAC experts can help evaluate your options.

How is the right size for a new furnace determined?

Sizing is crucial for efficiency and comfort. We perform a Manual J load calculation that considers your home’s square footage, insulation levels, and climate zone to determine the ideal BTU output. An oversized or undersized unit can lead to poor performance and a shortened system lifespan.

Can a new furnace increase my home's value?

Yes—replacing an outdated heating system can make your home more attractive to buyers. Many buyers view an aging furnace as a liability. A new, energy-efficient system can improve comfort, safety, and resale value.

When is the best time of year to schedule a furnace replacement?

The off-season (early spring or fall) is often ideal for scheduling a replacement. You may benefit from faster availability, potential seasonal discounts, and avoid the hassle of mid-winter breakdowns.

Is it worth investing in a high-efficiency furnace?

High-efficiency furnaces (90%+ AFUE) use less fuel and reduce monthly energy costs. Though upfront costs are higher, many homeowners see a return on investment within 5–7 years. These models may also qualify for energy rebates and tax incentives.

Can Gene May install a furnace I purchased elsewhere?

We only install systems we source directly. This ensures we can stand behind the quality of the product, provide a valid warranty, and guarantee proper sizing and compatibility. Our team is happy to help you select a trusted, reliable model.

What kind of warranty comes with a new furnace?

Most major furnace brands offer a standard 5-year warranty, which can extend to 10 years if registered within 90 days. Heat exchangers often carry longer warranties. Gene May also provides workmanship guarantees to ensure your complete satisfaction.

Where is the pilot light on my new furnace?

Most modern furnaces don’t use a standing pilot light. Instead, they feature electronic ignition systems, which are safer and more efficient. If you can’t find a pilot light, your system likely uses electric ignition—and that’s completely normal.

How long does furnace replacement take?

The typical installation takes between 4 to 8 hours, depending on system complexity and home size. Your technician will give you a time estimate based on your specific setup.

What questions should I ask before hiring an HVAC company?

Before scheduling a furnace replacement, ask:

• Are you licensed and insured?
• What brands do you carry and why?
• Can you help me take advantage of any rebates?
• What is included in the quote?
• What warranty do you provide?
• Do you have customer reviews or references?

Comparing these answers across providers can help you choose a team you trust. Gene May Heating & Cooling proudly serves Minooka, Joliet, Aurora, and surrounding suburbs with honest, reliable service.
