Your Local Air Conditioning Company for Chicago’s Northwest Suburbs

When your air conditioner can’t keep up — or quits in the middle of a July heat wave — you want a local A/C company that can diagnose the problem, explain your options, and get your home cool again fast. All Set Heating & Cooling provides professional air conditioning repair, replacement, installation, and maintenance for homeowners throughout Arlington Heights and Chicago’s Northwest Suburbs.

From emergency no-cool calls in a heat wave to planned upgrades to a high-efficiency system, our goal is simple: restore your comfort, control the humidity, and leave you All Set.

Local Cooling Experts
Serving Arlington Heights and Chicago’s Northwest Suburbs with air conditioning expertise built for humid Chicagoland summers.
Repair or Replace
We help you understand whether repairing your current A/C or replacing it makes the most sense for your home and budget.
Cool Air, Dry Air
Real summer comfort means humidity control, not just cold air. We size and tune systems so your home feels cool and dry — not clammy.

Local Air Conditioning Services

Whether you need a repair today, a spring tune-up, or you’re considering a new high-efficiency cooling system, All Set can help.

A/C Repair & Maintenance

Most summer breakdowns start as small problems a spring tune-up would have caught. Our repair and maintenance services keep your cooling dependable and efficient through the hottest stretch of the season.

A/C Repair • Seasonal Tune-Ups • Refrigerant & Leak Inspection • Coil & Condensate Cleaning • Thermostats • Preventive Maintenance Plans

If your air conditioner runs constantly, can’t keep up, leaves rooms too warm, or your cooling bills keep climbing, let All Set find the cause before it becomes a heat-wave emergency.

New A/C Install or Replace

If your A/C is limping through its second decade or your cooling bills keep climbing, a new high-efficiency system delivers colder air for less money — with quieter operation and better humidity removal.

Central Air Conditioners • Heat Pumps & Dual Fuel • Ductless Mini Splits • Load Calculation & Professional Sizing • All Major Brands

Every installation is sized right with a proper load calculation — because an oversized unit short-cycles and leaves humidity behind, while an undersized one runs nonstop and never catches up.

More Than Air Conditioning

Your A/C affects more than temperature. Airflow, humidity, filtration, and ventilation all influence how cool, comfortable, and healthy your home feels in summer — musty odors and sticky air are cooling-season problems too.

That’s why All Set also offers indoor air quality solutions, Air Score Testing, mini split systems, and HVAC maintenance plans designed to help your entire home perform better year-round.

Your Local AirAdvice Certified Consultant for Arlington Heights & Chicago’s Northwest Suburbs

Healthy indoor air starts with knowing what is actually happening inside your home. As your local AirAdvice Certified Consultant, All Set Heating & Cooling helps homeowners evaluate indoor air quality, comfort, airflow, humidity, filtration, and HVAC system performance before recommending improvements.

Instead of guessing or selling you equipment you may not need, we start with testing. Our $99 Air Score Test gives you a clearer picture of your home’s indoor environment so you can make informed decisions about your family’s comfort and air quality.

Local IAQ Expertise
Local indoor air quality testing for homeowners throughout Arlington Heights and Chicago’s Northwest Suburbs.
We Test First
We evaluate your home’s conditions before recommending HVAC, filtration, humidity, ventilation, or air quality improvements.
Whole-Home Approach
Air quality, heating, cooling, airflow, humidity, and filtration work together. We look at the whole system.

What Does an Air Score Test Check?

Your home can look perfectly clean while still having comfort or indoor air quality problems you cannot see. Air Score Testing helps us evaluate several important conditions that can affect how your home feels and how your HVAC system performs.

Particles & Contaminants
Evaluate airborne particles and conditions that may contribute to dust and poor indoor air quality.
VOCs & Chemicals
Identify conditions associated with volatile organic compounds and other indoor chemical sources.
CO₂ & Ventilation
Help determine whether your home is getting the ventilation and fresh-air exchange it needs.
Humidity & Moisture
Check whether indoor humidity is too dry, too damp, or within a comfortable range for your home.
Temperature & Comfort
Evaluate temperature conditions that may help explain hot rooms, cold rooms, or uneven comfort.
Airflow & Filtration
Look at conditions that may point to airflow restrictions, filtration concerns, or HVAC performance issues.

Know Your Air. Know Your Score. Know What to Do.

Dust everywhere? Musty odors? Allergy symptoms? Uneven temperatures? High utility bills? Frequent HVAC problems? These issues may have more than one cause, which is why simply replacing a filter or buying another piece of equipment does not always solve the problem.

An Air Score Test gives our local consultants more information about your home’s actual conditions. From there, we can explain what we found and discuss practical next steps based on your home rather than assumptions.

We Test Before We Recommend

Your Air Score results can help guide the next step. Sometimes the solution is simple. Other homes may benefit from improvements to filtration, humidity control, ventilation, airflow, maintenance, or the HVAC equipment itself.

Indoor Air Quality
Filtration, purification, ventilation, humidity control, and other whole-home air quality solutions.
HVAC Maintenance
Routine system care can improve reliability, airflow, efficiency, and year-round comfort.
Heating & Cooling
When equipment is contributing to the problem, we can discuss professional repair, replacement, or system upgrades.

Find out what your home is telling you.

You can’t see what’s in your air — but you can feel it. Dust everywhere. Allergies and coughing. Musty odors. Stale rooms. The All Set Air Score Test measures exactly what’s floating through your Northwest Suburbs home, so we can fix the cause — not just the symptom.

What We Measure

Using professional-grade smart air quality monitoring technology, we detect and track the three biggest threats to your indoor air:

Particulates

Dust, pollen, pet dander, and microscopic particles small enough to reach deep into your lungs — the stuff behind allergy flare-ups and that film on your furniture.

Carbon Dioxide (CO₂)

Elevated CO₂ makes rooms feel stuffy and leaves your family tired and foggy. It’s a telltale sign your home isn’t ventilating the way it should.

VOCs

Volatile organic compounds from cleaning products, paints, furniture, and building materials — the invisible chemicals behind odors and long-term air quality concerns.

How Your Air Score Test Works

1

We Test

A licensed All Set technician measures the particulates, CO₂, and VOCs in your home — real readings, not guesswork.

2

We Score

You get a clear, easy-to-understand Air Score showing exactly where your home stands and what’s affecting your air.

3

We Solve

We recommend only what your air actually needs — purification, filtration, duct cleaning, humidity control, or ventilation.

4

We Follow Up

We verify your results and protect them — because healthier air should stay that way.

Air That Fixes Itself

Testing is just the beginning. With smart monitoring connected to your HVAC system, poor air quality automatically triggers your system to cycle and clean the air. Paired with the right indoor air quality equipment, your home gets on-demand ventilation, purification, and filtration based on real-time readings — healthy air around the clock, without lifting a finger.

It’s the whole-home, whole-system approach: we don’t just look at the equipment. We evaluate everything that affects your air.
