What To Do When Your Furnace Stops Heating

A cold house can feel overwhelming, especially if you have young children, older family members, or pets. A few simple steps can help you stay safe and avoid unnecessary discomfort while you arrange professional help. None of these replace a visit from a trained technician, but they can give you a bit more control in the moment.

Quick Checks You Can Safely Try First

Start with the basics that you can safely check. Confirm that your thermostat is set to "heat" and that the temperature setting is higher than the current room temperature. If your thermostat uses batteries, see if they need to be replaced. Next, look at your electrical panel to see if the furnace breaker has tripped, and only reset it once if it has. You can also make sure that your furnace filter is not completely clogged, since severe blockage can affect performance.

When To Shut The System Off

There are also times when turning the system off is the safest choice. If you smell gas, notice a strong burning odor that does not fade after a few minutes of operation, or hear a loud scraping or banging noise from the furnace, switch the system off and keep it off until it can be inspected. These signs can point to issues that, in some cases, damage equipment if ignored or create safety risks for your household.

When To Call For Professional Help

Once you have taken these quick steps, reach out to our team so we can help you move from uncertainty to a clear plan. When you contact Heritage Heating & Cooling, we walk through what you are experiencing, help you decide whether you should shut the system down entirely, and schedule a visit that reflects how urgent your situation is. Our goal is to give you a calm, knowledgeable voice and a path back to a warm, comfortable home.

Our Furnace Repair Process: From Call To Comfort

Knowing what to expect when you call for service can take a lot of stress out of a no-heat situation. We follow a straightforward process so you are never left wondering what is happening or why. From the first conversation to the final system check, communication and respect guide every step.

What Happens When You Call

When you contact our office, a member of our team asks a few focused questions about your furnace, what you are hearing or feeling in the home, and how long the issue has been going on. No two situations are exactly alike, so this information helps us prioritize true no-heat emergencies and prepare the technician with the right tools and background. We strive to offer same-day appointments whenever our schedule and weather conditions allow, and we are available twenty four hours a day for urgent calls.

How Our Technicians Work In Your Home

On the day of service, one of our highly trained technicians arrives within the scheduled window in a clearly marked vehicle and with proper identification, so you always know who is at your door. Because every member of our field team is drug tested and background checked, you can feel more at ease about who is working in and around your home. The technician begins with a careful discussion of your concerns, then performs a detailed inspection of the furnace and related components.

Clear Explanations & Repair Options

After the inspection, we walk you through what we found in plain language. We explain which parts are failing or out of range, how that connects to the symptoms you noticed, and what your options are. In many cases, a focused repair can restore safe, reliable operation, and we outline the part and labor involved before we proceed. If we see signs that your system is nearing the end of its practical life, we share that information and, at your request, can also discuss replacement paths, including a free estimate on new equipment.

Respect For Your Home & Safety

Throughout the visit, our technicians treat your home or business with care. That includes protecting work areas, cleaning up after the job, and testing the furnace through a full cycle before they leave. As an EPA certified company, we also pay close attention to combustion safety, ventilation, and proper handling of any materials we remove. Before we consider the job complete, we make sure you understand what was done and that your system is operating the way it should at that time.

Heating Challenges In Our Area & How We Help

Winters in this part of Illinois can place a real demand on heating equipment. When cold snaps settle over O'Fallon and the rest of the Metro East region, furnaces often run for long stretches without much of a break. That strain can bring underlying issues to the surface and, in some homes, lead to sudden failures at the worst possible times.

Common Furnace Issues We See Locally

In our work across the area, we commonly see furnaces that are well beyond their intended service life, systems that have gone years without maintenance, and equipment that was never properly sized for the home in the first place. These factors can show up as rooms that never seem to get warm, systems that cycle on and off all day, or energy bills that climb higher than expected. Because we have been working in local neighborhoods since 2011, we understand the types of homes, duct layouts, and comfort expectations that show up again and again.

Supporting Local Homes & Small Businesses

We also support small businesses that depend on steady indoor temperatures to keep employees productive and customers comfortable. A restaurant in town, an office near a busy corridor, or a small retail shop all feel the impact quickly when the heat is off. Having a local team that can respond promptly and is familiar with common commercial equipment in this region helps reduce downtime and stress for business owners.

Solutions Built For Metro East Winters

Our experience with local conditions guides the way we look at every service call. When we recommend a repair, adjustments, or maintenance steps, we do so with an eye toward how your system will perform during real winter weather here, not just on a mild day. That perspective helps us focus on solutions that improve comfort and reliability, not just quick fixes that might not hold up when the temperature drops again.

Repair, Replacement & Protecting Your Investment

One of the biggest worries homeowners share with us is the fear of being told they must replace a furnace when a repair would have been enough. We take that concern seriously. Our role is to help you understand the condition of your system, outline realistic options, and support you while you decide what makes the most sense for your home and budget.

How We Help You Decide Between Repair & Replacement

During a service visit, we look at the age of your furnace, the nature of the current problem, and the history of past issues. If the system is in generally good shape and the needed work is limited to a specific part, a repair can often be a practical choice. In cases where the furnace is very old, has repeated breakdowns, or requires a major component that costs a large share of a new system, we explain that context and talk through how long you might reasonably expect the repair to last.

Free Estimates On New Equipment

When replacement becomes part of the conversation, we do not expect you to decide on the spot without information. We offer free estimates on new equipment so you can compare the cost of repair with the benefits of a more efficient, reliable system. As an Authorized Customer Care Dealer for American Standard, we can discuss a range of system options, with a focus on comfort, reliability, and how the equipment will perform in your specific home or business.

Warranties, Financing & Discounts

Financial protection is part of how we work to reduce stress around both repairs and replacements. We offer strong warranties on the parts and labor associated with our work, and we explain those details clearly before the job begins. For larger projects, we have flexible financing options available, including plans with 0 percent interest for qualifying terms, which can make a new system more manageable. We also extend discounts to veterans, active military members, and senior citizens as a way of giving back to those who have given so much to our community.

Frequently Asked Questions

How fast can your team get to my home when I have no heat?

When you have no heat, we treat your situation as a priority. Our team is available twenty four hours a day, and we work to schedule no-heat calls as quickly as possible, often with same-day appointments when our workload and weather conditions allow. Because we are based in this area, our technicians are already working nearby, which can shorten travel time in many cases. During periods of extreme cold, demand naturally increases, so we schedule visits based on urgency and arrival order. When you call, we give you a realistic arrival window and keep you updated if conditions change.

Can you fix my older furnace or will you just recommend replacement?

We repair many older furnaces, and we do not assume replacement is the answer just because a system has some age on it. Our technicians evaluate how the unit is operating, what specific parts have failed, and how often you have experienced problems in the past. If the repair is straightforward and the rest of the equipment is in reasonable condition, we explain that and move forward with your approval. When a furnace is very old or requires major work that approaches the cost of a new system, we share that information and, if you wish, provide a free estimate on replacement so you can compare options. The goal is to give you clear information, not pressure you into a decision.

What will it cost to have you come out and diagnose my furnace?

The cost of a visit includes both the time it takes for a trained technician to travel to your home and the detailed diagnostic work needed to identify the problem accurately. Specific pricing can vary based on the nature of the call and the time of day, particularly for after-hours emergencies. When you contact our office, we explain what to expect for the initial visit so there are no surprises. Before any repair work begins, we review the recommended solution, the parts involved, and the total cost so you can decide how you would like to proceed.

Are your technicians background checked before coming into my home?

Yes, every technician we send to your home has been background checked and drug tested as part of our hiring and employment process. We know it takes trust to open your door to someone, especially during an emergency or outside regular business hours. Our team members also receive ongoing technical training and are expected to follow clear standards for professionalism and respect in every home and business they enter. When a Heritage Heating & Cooling technician arrives, you can expect a uniformed professional who treats your property and your family with care.

Do you work on all furnace brands and types?

We service a wide range of furnace brands, makes, and models that are commonly found in homes and small businesses in this region. Our technicians are trained to diagnose and repair many different gas and other forced-air systems, which helps us support customers no matter what name is on the unit. In addition to broad brand familiarity, we are an Authorized Customer Care Dealer for American Standard, which reflects additional training and support with that manufacturer. If you are unsure whether we can work on your specific furnace, our team can usually confirm that when you call by asking a few quick questions about your equipment.

Can you help me avoid future furnace breakdowns?

While no mechanical system can be made failure proof, regular care can significantly reduce the likelihood of sudden breakdowns. We offer ongoing maintenance services that include cleaning key components, checking safety controls, and verifying that your furnace is operating within recommended ranges. During these visits, we can often spot developing issues before they turn into a larger problem, which may give you more options and time to plan. We also share simple steps homeowners can take, such as changing filters on an appropriate schedule and keeping vents clear, to support more reliable operation throughout the heating season.

Do you offer any discounts or financing for furnace work?

We know that unexpected furnace expenses can strain a household or small business budget. To help, we offer special discounts for veterans, active military personnel, and senior citizens. For larger repairs and system replacements, we also have financing options available, including plans with 0 percent interest for qualifying terms, which can spread the cost out over time. When we discuss your repair or replacement options, we can review the programs that may apply to your situation so you can choose an approach that fits your financial needs as well as your comfort goals.
