Reliable Furnace Service To Restore Comfort Quickly

A furnace issue rarely happens at a convenient time. You might notice cool air coming from the vents at night, hear new banging or squealing noises, or wake up to a system that will not turn on at all. In colder Illinois weather, that can quickly turn from an inconvenience into a real comfort and safety concern.

When you call us for help, we focus on getting you warm again as quickly and safely as possible. Our team offers 24/7 emergency response and strives to provide same-day appointments whenever our schedule and technician availability allow it. We handle no-heat calls, intermittent operation, short cycling, and performance issues for both homes and small small commercial spaces.

Because we work on all major furnace brands and models, you do not have to worry about tracking down a specific manufacturer contact. Our technicians arrive prepared to diagnose ignition problems, airflow issues, control failures, or other common causes of poor heating performance. We walk you through what we find in simple terms, answer your questions, and help you choose the solution that fits your situation.

Why Homeowners Trust Our Team For Furnace Repairs

Inviting a heating contractor into your home or business is a matter of trust. You want to know the person at your door is qualified, safe, and focused on solving your problem, not just selling the largest project. At Heritage Heating & Cooling, that trust starts with who we are and how we operate every day.

We are a family-owned, veteran-owned company that has been serving customers since 2011. Over the years, we have completed tens of thousands of heating and cooling services for property owners in this region. That experience means our team has seen a wide variety of furnace problems and system types, so we can often pinpoint issues quickly and recommend practical options.

Your safety and peace of mind are a priority for us. Our technicians are drug-tested and background-checked before they enter your home or workplace. As an EPA certified company, we follow standards for handling equipment and refrigerants, and we pay close attention to combustion safety and ventilation on gas furnaces.

We also back our work with solid protections. We offer warranties on parts and labor, so you have added confidence in the repairs and installations we complete. Our status as an Authorized Customer Care Dealer for American Standard, along with a 100 percent satisfaction rating on Angi, provides additional proof that homeowners and small businesses feel comfortable relying on our team for their heating needs.

What To Do When Your Furnace Stops Working

A furnace failure can feel stressful, especially on a cold night or early morning. Knowing a few simple steps can help you stay safe and avoid unnecessary worry while you reach out for help from a professional.

Start with a few safe checks:

• Make sure your thermostat is set to heat and that the temperature is higher than the current room reading.
• Check that the furnace switch near the unit is in the "on" position and that the breaker in your electrical panel has not tripped.
• Look at your air filter. If it is extremely dirty, replacing it may help airflow and allow the system to operate more normally.

Watch for warning signs that require a call right away:

• Smell of gas or strong burning odors, other than a light dust smell on first use for the season.
• Repeatedly tripping breakers, frequent shutoffs, or loud new noises such as banging or grinding.
• Visible signs of scorching around the furnace or vents.

If you notice any of these conditions, shut the system off at the thermostat and, where appropriate, the breaker, then contact a qualified HVAC company promptly. Our team can walk you through any immediate safety steps over the phone, then schedule a visit to inspect the system, identify the cause, and work to restore proper operation. You do not have to guess at what is happening or try risky repairs on your own.

Our Furnace Repair, Maintenance, & Replacement Services

Your heating system may need different types of service at different points in its life. We provide a full range of repair, maintenance, and replacement options so you can call on us for nearly any heating concern.

Furnace Repairs For Common Heating Problems

We routinely help homeowners with issues such as:

• Ignition problems and pilot or hot surface igniter failures that keep the burner from coming on.
• Blower motor or fan problems that reduce airflow and make rooms feel unevenly heated.
• Limit switch and control board problems that cause short cycling or frequent shutoffs.
• Thermostat related concerns that prevent the furnace from responding correctly to temperature changes.

Our technicians evaluate the entire heating system, not just the most obvious part. This helps us track down root causes, such as airflow restrictions or duct issues, instead of only treating symptoms. We explain repair options and associated costs so you can decide how to move forward.

Preventive Furnace Maintenance & Tune-Ups

Regular maintenance visits can include:

• Seasonal inspections to look for worn components and potential safety concerns.
• Cleaning and adjustments that can support efficient operation and consistent comfort.
• Performance checks that help catch developing issues before they turn into a no-heat situation.

Scheduling maintenance before the heaviest heating months can reduce the likelihood of unexpected breakdowns and may help your furnace run more smoothly. Our goal is to keep your system dependable, not just fix it when it fails.

Thoughtful Furnace Replacement & Installation

When replacement is the right move, we help by:

• Guiding you on when replacement may make more sense than repeated repairs, especially for older or inefficient units.
• Providing free estimates on new equipment so you can compare options without added pressure.
• Installing quality systems, including American Standard equipment, with attention to proper sizing and setup.

When a new furnace is the best choice, we walk you through the process step by step. That includes discussing comfort goals, energy efficiency preferences, warranties, and financing options that may be available. We work to provide solutions that fit both your home and your budget.

Straightforward Pricing, Warranties, & Financing Options

Cost is often one of the biggest worries when something goes wrong with a heating system. We believe clear information and flexible options go a long way toward reducing that stress and helping you make confident decisions.

When you call us for a repair visit, our technicians start by inspecting your furnace and identifying what is going on. They then explain their findings in plain language and go over the recommended options and pricing with you before any work begins. You stay in control of the decision, whether that means choosing a repair or discussing replacement.

We support our work with warranties on parts and labor. These protections are designed to give you added assurance that if an issue related to the work we performed arises within the warranty period, you have support instead of facing the same problem alone. Specific warranty terms can vary by equipment and service type, and our team will outline those details during your visit or estimate.

For larger projects, such as a new furnace installation, we understand that paying in full upfront can be difficult. We offer financing options that can include 0 percent interest for up to 60 months on qualifying equipment through approved programs. We also provide special discounts for veterans, military personnel, and senior citizens as part of our commitment to serving those who have served and to supporting our community. These options are intended to make necessary heating improvements more manageable without sacrificing quality or safety.

How Our Technicians Care For Your Home Or Business

The experience you have during a service visit matters just as much as the technical outcome. Our technicians work to treat every home and business with respect, from the moment they arrive until the job is complete.

When a technician from Heritage Heating & Cooling comes to your property, you can expect a professional appearance and a clear introduction. They explain why they are there and what they will be checking, then get to work assessing the furnace and related components. As they move through the inspection, they keep an eye out for both operational and safety issues so you have a complete picture of your system’s condition.

Before any repair begins, our technicians review their findings with you in everyday language. They discuss available options, answer your questions, and confirm your approval before they proceed. This way, you know what is happening and why, rather than wondering what is being done to your equipment.

During the visit, our team is mindful of your space. Technicians use appropriate protective measures, such as shoe covers or drop cloths where needed, and they clean up their work area when the job is finished. Before leaving, they can walk you through any changes made, show you how to use new equipment or thermostat settings, and share simple maintenance tips that may help support long-term performance.

Our motto is that we are not comfortable unless you are. That applies to the temperature in your home and to the way you feel about the people working there. Combining background checks, drug testing, training, and respectful on-site habits helps us honor that promise.

Frequently Asked Questions

How Fast Can You Get My Heat Back On?

Response time depends on factors like current call volume, time of day, and weather conditions, but our goal is always to help you as quickly and reasonably as we can. We offer 24/7 emergency service and work to prioritize no-heat situations so families and businesses are not left without warmth longer than necessary. In many cases, we are able to schedule same-day visits, particularly during normal business hours. When you call, our team will let you know the first available appointment window and what you can expect for arrival timing. Once on site, our technicians focus on efficient diagnosis so that if a repair is possible that day, you can get back to a comfortable space sooner.

Will You Tell Me The Price Before Starting Any Furnace Work?

Yes, our technicians review recommended work and associated costs with you before proceeding. The visit typically begins with an inspection and diagnosis of your furnace issue. Once they understand what is causing the problem, they explain your options, such as specific repairs or, if needed, replacement discussions. You receive clear pricing information so you can decide how to move forward based on your budget and priorities. We do not move ahead with work until you approve the plan, which helps prevent surprises on your final bill.

Can Your Team Repair My Brand Of Furnace?

Our technicians are trained to work on all major furnace brands, makes, and models. That includes a wide range of gas and electric systems that are common in homes and small commercial buildings. We are also an Authorized Customer Care Dealer for American Standard, which reflects additional training and support related to that brand. If you are unsure about your equipment type, you can share the model information when you call, and our team can confirm what to expect. In most cases, we arrive prepared with parts and tools suitable for many different systems.

How Do I Know If I Should Repair Or Replace My Furnace?

The right choice depends on the age of your furnace, how often it has been breaking down, and the cost of the current repair compared with the value of the system. For example, older units that have required several service calls in recent seasons or that struggle to heat your home evenly may be good candidates for replacement. In contrast, a newer furnace with a single, straightforward issue often makes sense to repair. During a visit, our technicians can discuss these factors with you, outline what a repair would involve, and provide a free estimate for new equipment if you want to compare. We work to give you the information you need to make a decision that fits your home and budget.

What Safety Steps Do Your Technicians Follow In My Home?

Safety is a central part of how we operate. Our technicians are drug-tested and background-checked before they represent our company in the field, which helps you feel more comfortable inviting them into your home or business. During a furnace visit, they follow standard safety practices such as checking for gas leaks, verifying proper venting, and confirming appropriate combustion on gas furnaces. They also turn off power to the equipment as needed while working and follow manufacturer and industry guidelines when making repairs. If they notice any safety concerns that fall outside the immediate issue you called about, they will explain those findings and discuss recommended next steps.

Do You Offer Any Discounts Or Financing For Furnace Replacement?

We offer several ways to help make larger heating projects more manageable. For qualifying new furnace installations, we provide financing options that can include 0 percent interest for up to 60 months through approved programs. Our team can go over available financing choices and basic terms during your estimate, so you know what to expect. We also extend special discounts to veterans, military personnel, and senior citizens as part of our commitment to the community. These programs are designed to reduce some of the financial pressure that can come with major heating decisions.

Is Regular Furnace Maintenance Really Worth It?

Regular maintenance can provide meaningful benefits for many heating systems. During a tune-up visit, our technicians inspect key components, look for early signs of wear, and make adjustments that support safe and efficient operation. This attention can help catch small issues before they turn into a complete breakdown, especially during the coldest parts of the season. Maintenance visits also provide an opportunity to check for safety concerns, such as improper venting or combustion problems. While no service can prevent every future issue, many homeowners find that consistent maintenance helps their furnace run more reliably and can support a longer service life.
