Call (331) 296-4956 for a quote.
From aging systems to brand-new installs, we handle the full range of heating and cooling work across DuPage County. Residential customers, commercial tenants, property managers, and building owners all call us for the same reason: they need the work done right the first time.
Here is what we cover:
Your system is in good hands with us.
The hardest part of an HVAC problem is knowing when to call, and with air conditioning, the signs are usually clear: the system is blowing warm air, the house is not cooling down, the unit stopped running entirely, or certain rooms feel stuffy while others stay comfortable. Those symptoms point to real problems that get worse the longer they sit.
When we come out, we look at the whole picture. That means checking the condenser and compressor, inspecting the evaporator coil, testing refrigerant levels, and servicing the air handler and blower. Uneven temperatures and poor airflow often trace back to a single point of failure, and we find it.
We give you honest recommendations on repair versus replacement, never an upsell. If a repair makes financial sense, we say so. If the equipment is too far gone, we tell you that too, along with straightforward pricing so you know what to expect before any work begins.
When the technician arrives, the real work begins. A furnace that is not working, blowing cold air, or cycling on and off without heating the house is not a problem to wait out, especially during a DuPage County winter. We carry parts for the most common furnace failures and aim to get same-day service out to you when the heat goes down.
We handle emergency heating repair calls alongside scheduled service visits, so whether you woke up to a cold house or noticed your system struggling during a tune-up, we can help. Speaking of tune-ups, an annual inspection before the heating season is one of the best ways to avoid a no-heat call in February. We check ignition, heat exchangers, burners, filters, and controls so the furnace is ready when the temperature drops.
Give us a call and we'll get the comfort back.
Wheaton sits squarely in a four-season climate. Winters are cold enough to demand a reliable heating system, and summers bring the kind of heat and humidity that pushes air conditioning and indoor air quality equipment hard. The services below come up constantly in this area because the climate calls for them.
When a system is aging, running inefficiently, or simply beyond repair, full replacement is the right call. We size and match equipment to the home or building, coordinate the installation, and commission the new system properly so it runs the way it should from day one.
Wheaton's climate means both sides of the equation matter. A new furnace without an updated AC, or the reverse, often leaves one half of the system underperforming. We handle full paired replacements and single-unit swaps, and we walk you through the options with honest guidance on equipment choices and what the work involves. Experienced technicians who respect your home handle every step of the install.
Heat pumps are gaining ground across the Midwest as an efficient alternative for both heating and cooling. A single system handles both seasons, and modern cold-climate heat pumps hold up well into the lower temperatures Wheaton sees each winter. We install and service ducted heat pump systems as well as mini-split and ductless options for spaces where running new ductwork is not practical.
If your heat pump is already in place and not performing, we handle repair and service calls too. A heat pump blowing cold air in heating mode or failing to cool in summer is a diagnostic call we make regularly.
Illinois summers are humid, and that humidity makes indoor air feel heavier and harder to cool even when the AC is running. A whole-home dehumidifier works alongside your existing HVAC system to pull excess moisture out of the air before it circulates through the house.
The result is a more comfortable indoor environment and less strain on the cooling system. We install whole-home dehumidification equipment integrated directly with the HVAC system, and we pair that work with air filtration upgrades when indoor air quality is a broader concern.
If you're not sure your system can keep up, the problem is sometimes the equipment, but often it is something else entirely. A failing thermostat, leaking ductwork, or poor air filtration can make a perfectly good HVAC system perform well below its potential.
We install programmable and smart thermostats, replace thermostats that have stopped responding accurately, and set up smart controls that give you better visibility into your system's performance. Ductwork repair and sealing is another area where small problems have a big impact. Leaking ducts push conditioned air into walls and attics instead of into the rooms where it belongs, which drives up energy costs and creates uneven temperatures throughout the building.
On the indoor air quality side, we install air filtration systems, UV air purifiers, and air scrubbers that integrate with your existing HVAC equipment. Let us handle the install and the permits.
Not every HVAC company works the same way, and when your system goes down in the middle of a heat wave or a cold snap, response time matters. We take emergency no-heat and no-cool calls for both residential and commercial customers in Wheaton and across the surrounding DuPage County communities.
Same-day availability means we aim to get a technician out the day you call, not a day or two later. We find the fault. We make the repair. We restore the comfort.
Offices, retail spaces, restaurants, and commercial properties throughout the area count on functional heating and cooling to keep employees comfortable and customers coming back. A system failure in a commercial setting costs more than comfort; it can affect operations and revenue.
We handle commercial AC repair, commercial heating repair, full HVAC system installation, and ongoing maintenance for businesses of all sizes. Work is performed by qualified HVAC technicians who understand the demands of commercial equipment and the schedules that come with it. We provide straightforward pricing and estimates before the work starts so there are no surprises on the invoice.
A spring tune-up before cooling season and a fall tune-up before the furnace has to carry the load are two of the most cost-effective things you can do for your HVAC system. Both visits follow the same principle: catch small problems before they become expensive failures.
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. We serve both residential and commercial maintenance clients, and we bring locally owned and operated HVAC technicians to every visit.
We started Experts Of HVAC in 2022 with a straightforward goal: provide reliable heating and cooling service to the people and businesses in this community without the runaround. Four years in, that has not changed.
We work throughout Wheaton and serve customers in Naperville, Glen Ellyn, Carol Stream, Lombard, Winfield, and Warrenville. When you call, you reach someone who knows the area and the work. Pricing is honest and explained up front. Repair versus replacement guidance comes without pressure. We live here. We keep this area comfortable. We stand behind our work.
Call us at (331) 296-4956 as soon as you notice the problem. We offer same-day and after-hours emergency service for no-heat and no-cool situations in Wheaton and across DuPage County, so you do not have to wait until the next business day. The sooner we know what is happening, the sooner we can get a technician headed your way.
Yes. We aim to get a technician out the same day you call for both emergency and urgent non-emergency situations. Availability can vary depending on the time of day and call volume, so calling early gives you the best chance of a same-day appointment. Reach us at (331) 296-4956 and we will tell you what we can do.
We are available seven days a week, including Saturdays and Sundays. Heating and cooling problems do not wait for Monday, and neither do we. Call (331) 296-4956 to schedule a weekend service visit or report an emergency.
We ask a few quick questions about what your system is doing so we can send the right technician with the right parts. Once we have a clear picture of the situation, we confirm a service window and get someone headed to your home or property. When the technician arrives, they inspect the system, explain what they find, and give you pricing before any work begins.
Yes. We work with offices, retail spaces, restaurants, apartment buildings, and other commercial properties throughout Wheaton and DuPage County. Commercial HVAC repair, heating service, AC service, and ongoing maintenance are all part of what we do. Call us to discuss your property's needs and we will schedule accordingly.
The honest answer depends on the age of the equipment, the cost of the repair, and how efficiently the system is running. We give you honest recommendations on repair versus replacement, never an upsell, so you get a clear picture of both options with real numbers before you decide. If a repair makes financial sense, we say so. If it does not, we tell you that too.
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. Transparent pricing is something we take seriously on every call.
Deposit requirements can vary depending on the scope of the work, particularly for full system installations or equipment replacements. We discuss payment expectations up front so there are no surprises. Call us at (331) 296-4956 and we can walk you through what to expect for your specific job.
We accept common payment methods and will confirm the options available when you call or when the technician is on site. We want the payment process to be as straightforward as the rest of the job. Reach us at (331) 296-4956 with any questions before scheduling.
When your heating or cooling system needs attention, do not wait for a small problem to become a big one. Experts Of HVAC is available for same-day service calls, seasonal maintenance, full system replacements, and everything in between. Honest pricing, qualified technicians, and work you can count on.

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.
