We live here. We keep this area comfortable. We stand behind our work.
Experts Of HVAC is a locally owned and operated HVAC company serving Wheaton and the surrounding communities of DuPage County. We work with homeowners, property managers, and business owners across the area, handling everything from urgent no-heat calls in January to full system replacements on a planned schedule. Local roots mean we're invested in getting your comfort right. Our technicians are locally owned and operated HVAC technicians who know this area, know the equipment common to it, and show up ready to work. Your system is in good hands with us.
Not every HVAC company works the same way, and when we started in 2022, we built this company around a straightforward idea: do the work right, be honest about what a system needs, and treat every home or building the way we'd want our own treated.
We founded Experts Of HVAC right here in DuPage County, starting with a small crew and a commitment to earning the trust of local customers one job at a time. In the years since, we've grown by doing exactly that. We serve residential customers in single-family homes and multi-unit properties, and we work with commercial clients who need reliable heating and cooling they can count on without disruption to their operations.
Our team brings honest recommendations on repair versus replacement, never an upsell. When a system can be repaired, we say so. When the repair cost doesn't make sense against the age and condition of the equipment, we'll tell you that too, with the numbers to back it up. That's how we think every HVAC company should operate.
From aging systems to brand-new installs, we handle the full range of residential and commercial HVAC work. That means air conditioner repair and service, furnace repair and heating service, heat pump installation and repair, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, seasonal maintenance and tune-ups, and emergency no-heat and no-cool service. We're not a specialty shop that does one thing. We're the contractor you call when something goes wrong, when it's time to replace aging equipment, or when you want to make sure everything is running right before the season changes.
When an air conditioner stops cooling, the diagnosis matters as much as the repair. We check refrigerant levels, inspect condenser and compressor components, test electrical connections on the unit, and trace airflow problems back to their source. A visit from our technicians means a clear explanation of what's wrong and what it takes to fix it before any work begins.
When repair isn't the right call, whether the system is too old, too inefficient, or too far gone to justify the cost, we'll walk you through central air installation and AC system replacement options. Call for a quote and we'll give you honest numbers for both paths.
Illinois winters are not forgiving, and in Wheaton, a furnace that isn't working is a problem that needs attention the same day. We diagnose furnaces that won't ignite, systems that cycle on and off without warming the space, and units producing heat but not distributing it evenly. We repair heating systems across a wide range of makes, models, and ages, and when a furnace has reached the end of its useful life, we handle the replacement from start to finish.
Same-day furnace repair is available when you need it most. Give us a call and we'll get the comfort back.
Heat pumps are a growing choice for DuPage County homeowners who want a single system that handles both heating and cooling efficiently. We service heat pumps that have stopped performing, diagnose refrigerant issues and reversing valve faults, and install new heat pump systems when a homeowner is ready to upgrade.
Mini-split and ductless systems fall into this same category. If you're heating or cooling a space that doesn't have existing ductwork, or if you want independent control over a room or addition, a ductless system may be the right fit. We'll walk you through the options.
These three areas don't always get the attention they deserve, but they have a direct effect on how well your heating and cooling system performs.
Leaking or poorly sealed ducts can send conditioned air into walls and crawl spaces instead of into the rooms where it belongs. We inspect ductwork, seal leaks, and repair damaged sections to bring airflow back to where it should be. Experienced technicians who respect your home take care to work cleanly and leave the space the way they found it.
Thermostat upgrades are one of the most straightforward improvements a homeowner can make. A smart thermostat or programmable control gives you better management of your system, and our technicians handle the installation and setup so everything works from day one.
Indoor air quality is a real concern across the seasons here. Winter heating dries the air significantly, and spring brings pollen and allergens that circulate through the home. We install whole-home air filtration systems, air purifiers, and humidification equipment that work alongside your existing HVAC system to keep the air inside healthier and more comfortable year-round.
The hardest part of an HVAC problem is knowing when to call, but when there's no heat in February or no cooling during a July heat wave, the answer is simple: call now.
We're available for HVAC emergencies around the clock. A no-heat or no-cool situation isn't something that can wait for a regular business-hours appointment, and we don't treat it like one. We find the fault. We make the repair. We restore the comfort.
Same-day service is available for urgent situations, and our technicians arrive with the tools and parts on hand to handle the most common failures on the first visit. Let us handle the install and the permits.
Scheduling HVAC service with us is straightforward.
That's it. No guesswork, no surprise charges, no pressure.
If you're not sure your system can keep up, that uncertainty alone is worth a call. We work with homeowners across Wheaton and DuPage County, servicing all system types and ages, from older equipment that needs careful maintenance to newer systems that just need a seasonal check.
We also work with commercial clients. Offices, retail spaces, and multi-tenant properties all depend on reliable heating and cooling, and property managers in particular need a contractor who shows up on schedule and communicates clearly. We handle commercial HVAC repair, commercial heating service, commercial AC service, and commercial HVAC maintenance with the same reliability we bring to residential work.
Beyond Wheaton, we serve the surrounding communities throughout the county, including Carol Stream, Glen Ellyn, Winfield, Lombard, Warrenville, and West Chicago. If you're nearby, we're your local HVAC contractor.
When the technician arrives, the real work begins, and a maintenance visit is no different. Seasonal tune-ups are the single most effective way to avoid emergency calls and extend the life of your equipment.
We schedule spring AC tune-ups to get cooling systems ready before summer heat sets in, and fall furnace tune-ups to confirm heating systems are operating safely and efficiently before the first cold snap. A proper maintenance visit covers the full inspection: cleaning, testing, adjusting, and identifying anything that needs attention before it becomes a failure.
Call to request an estimate on a seasonal maintenance visit. A well-maintained system also tends to run more efficiently, which shows up in lower energy costs over time.
We tell you what something costs before we do it. That applies to repairs, installations, replacements, and maintenance visits. There are no surprise fees added after the fact, and we don't push customers toward more expensive options when a simpler solution will solve the problem.
Dependable service. Honest rates. Local HVAC know-how.
When you call for a quote, we'll give you a clear number based on what your system actually needs. If a repair and a replacement are both reasonable options, we'll lay out both with honest numbers and let you decide. That's the only way we know how to work.
We started in 2022 with a straightforward goal: provide reliable heating and cooling service to the people and businesses in this community and do it honestly. DuPage County has a genuine four-season climate that puts real demand on HVAC equipment, and we saw a need for a locally owned contractor that treats customers the way a neighbor would. Four years in, that has not changed.
Yes. This is a locally owned operation, and the people running it are personally invested in the quality of every job. When you call, you are reaching someone who is accountable for the work, not a manager removed from the field. That personal accountability is something we built into the business from the start.
Wheaton and the surrounding DuPage County communities have a mix of older homes and newer construction, each with its own equipment quirks and ductwork characteristics. Our technicians work in this area every day and are familiar with the makes, models, and installation styles common to local homes. That local knowledge means we spend less time guessing and more time solving the actual problem.
We do. If something we installed or repaired is not performing the way it should, we want to know and we will make it right. We are locally owned and personally accountable, which means our reputation in this community is directly tied to every job we complete.
We are a focused local operation, not a large regional company. Our team is sized to serve Wheaton and the surrounding DuPage County area well, with technicians who know the work and the community. If you want to know more about our current capacity or scheduling, call us at (331) 296-4956 and we can talk through what works for your timeline.
We built this company around honest work and straightforward communication. That means clear pricing before any work starts, honest guidance on repair versus replacement without pressure toward the more expensive option, and experienced technicians who respect your home on every job. Local roots mean we are invested in getting your comfort right, and that shapes how we operate.
Yes. Diagnosing and repairing modern HVAC systems accurately requires the right diagnostic tools, and we equip our technicians accordingly. Showing up with the right equipment means fewer return visits and faster resolutions for our customers. It is part of doing the job right the first time.

How do I know whether my system needs a repair or a full replacement?
The honest answer depends on the age of the equipment, the cost of the repair, and how efficiently the system is currently running. We give you a clear picture of both options with real numbers before you decide. If a repair makes financial sense, we say so. If the equipment is too far gone, we tell you that too. Our goal is an honest recommendation, not an upsell.
What are the signs that my furnace or AC is failing and needs attention soon?
For a furnace, watch for cold air from the vents, the system cycling on and off without heating the house, unusual noises, or a sharp rise in your heating bills. For an AC, warm air from the vents, the system running constantly without cooling the home, or ice forming on the unit are all signs something is wrong. Catching these early usually means a simpler, less expensive fix.
How often should I schedule maintenance and tune-ups?
Twice a year is the standard recommendation: a spring tune-up before cooling season and a fall tune-up before the furnace has to carry the load. Both visits follow the same principle, which is catching small problems before they become expensive failures. Skipping maintenance is one of the most common reasons systems fail early.
Same-Day and Emergency Availability
When your heat or cooling goes down, we aim to get a technician out the same day you call. We take emergency no-heat and no-cool calls for residential and commercial customers across DuPage County.
What does a seasonal tune-up actually cover?
During a maintenance visit we inspect, clean, and test the system from top to bottom. That includes checking refrigerant charge, testing ignition and burner operation, inspecting heat exchangers, cleaning coils, and verifying that controls and safety switches are working correctly. You get a clear picture of the system's condition before the season puts real demand on it.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually trace back to one of a few causes: leaking or undersized ductwork, a failing blower motor, a refrigerant or airflow problem, or a thermostat that is not reading conditions accurately. We look at the whole picture when we come out rather than guessing at a single cause. Duct leaks in particular are a common culprit that often goes undiagnosed for years.
What do strange noises from my HVAC unit usually mean?
Banging or clanking often points to a loose or broken component inside the blower or air handler. Squealing can indicate a worn belt or bearing. Clicking at startup or shutdown is usually normal, but clicking that continues during operation can signal a control or ignition problem. Any noise that is new or getting worse is worth a call so we can take a look before the problem grows.
Transparent Upfront Pricing
We give you clear pricing before any work begins and we do not add surprise fees after the fact. If a job turns out to be more complex once we open things up, we talk to you before proceeding.
Is a heat pump a good option for a home in Wheaton?
Heat pumps have become a practical choice across the Midwest as equipment has improved. Modern cold-climate heat pumps hold up well into the lower temperatures Wheaton sees each winter, and a single system handles both heating and cooling efficiently. Whether a heat pump is the right fit depends on your home, your existing equipment, and your goals. We walk through the options honestly so you can make an informed decision.
How do ductwork leaks affect my energy bills and comfort?
Leaking ducts push conditioned air into walls, attics, and crawl spaces instead of into the rooms where it belongs. The result is uneven temperatures throughout the home and a system that works harder than it needs to, which drives up energy costs. Sealing those leaks is one of the more impactful improvements you can make without replacing any equipment.
Work Performed by Qualified HVAC Technicians
Every installation, repair, and maintenance visit is handled by qualified HVAC technicians who understand both residential and commercial equipment and the demands that come with each.
Do I need to be home when the technician comes out?
Yes, an adult should be present for the visit. The technician needs access to the equipment, and we want to be able to walk you through what we find and confirm pricing before any work begins. If scheduling is a concern, call us and we will work with you to find a window that fits.
How does emergency service work if my heat or AC goes out completely?
Call us as soon as you notice the problem. We take emergency no-heat and no-cool calls for both residential and commercial customers in Wheaton and across DuPage County. We aim to get a technician out the same day you call. The sooner we know what is happening, the sooner we can get someone headed your way.
What causes a system to short-cycle, and is it serious?
Short-cycling means the system is turning on and off more frequently than it should without completing a full heating or cooling cycle. Common causes include an oversized system, a refrigerant problem, a dirty filter or coil restricting airflow, or a failing component like a pressure switch or blower motor. It puts extra wear on the equipment and should be diagnosed promptly before it leads to a larger failure.
Call us at (331) 296-4956 and we will help you figure out exactly what your system needs, with honest guidance and straightforward pricing before any work begins.
