Wise-Air Heating, Air Conditioning and Refrigeration has been the go-to heating and cooling contractor for Palatine homeowners, landlords, property managers, and businesses since 1999. We handle repair, service, and installation for all makes and models, from a single-family home on the north side of town to a commercial property across Cook County. Same-day availability, up-front pricing, and work performed by qualified HVAC technicians. Call for a quote: (224) 539-2898
A home that heats and cools right is a comfortable home, and getting there starts with a contractor who handles everything under one roof. We cover the full range: AC repair and service, furnace repair, heat pump service, system installation and replacement, thermostat and smart-control installation, ductwork repair and sealing, indoor air quality, and seasonal maintenance. Whether you are dealing with uneven temperatures room to room, a condenser that stopped running, a compressor that is short-cycling, or an air handler blowing weak, we diagnose it and fix it right.
Commercial customers get the same attention. Office buildings, retail spaces, and rooftop units are all in our wheelhouse. We approach every job with clear communication from the first call to the final test, so you always know where things stand and what comes next. Leave the heating and cooling to us.
We show up on time and ready to work, which matters when your air conditioner quits mid-July. Common calls include central air blowing warm, a system that will not turn on, or a unit that ran fine last season and stopped working overnight. A service visit covers full diagnosis, refrigerant leak check, condenser and compressor inspection, and evaporator coil evaluation. We find the problem, explain it clearly, and give you options before any work begins.
Sometimes a repair makes sense. Sometimes the system is old enough, inefficient enough, or broken down enough that replacement is the smarter call. We install central air systems, new AC units, and ductless mini-split systems for spaces without existing ductwork. Every estimate comes with no-pressure estimates, priced up front, so you can make a confident decision without feeling rushed. One call, and a technician is on the way.
No heat in the house on a cold Illinois night is not something to wait on. We handle furnace failures of all kinds: no heat, intermittent heat, a furnace that starts and shuts off, or one that simply will not respond. A diagnostic visit covers the heat exchanger, ignition system, airflow, and controls. We also service and repair boilers for homes and buildings running hydronic heating systems. We stand behind every system we service, and that commitment starts with an honest diagnosis.
Heating and cooling a home right takes the right tools and a trained hand, and that is especially true when it is time to replace aging equipment. A furnace pushing 15 to 20 years, one that has needed repeated repairs, or one running well below its rated efficiency is usually a replacement candidate. We handle furnace installation, full heating system replacement, and boiler installation for residential and commercial properties. Pricing is straightforward, and we will walk you through your options before you commit. Call for a quote at (224) 539-2898 and we will get the process started.
Palatine sits squarely in the Chicago suburbs, where winters run hard and summers bring heat and humidity in equal measure. That four-season reality puts specific demands on residential and commercial HVAC systems across Cook County, and it shapes the work we do most often.
Illinois winters are not gentle on aging equipment, and summers push central air systems to their limits for months at a stretch. When a furnace and AC unit are both approaching the end of their service life, replacing them together as a matched system often makes more sense than patching one while the other fails a season later. Signs it is time include rising energy bills, inconsistent comfort, frequent breakdowns, or equipment that is simply too old to run efficiently. We handle the full replacement from equipment selection through installation and system testing, with an eye toward long-term performance and energy efficiency.
Heat pump adoption is growing steadily across the Chicago suburbs as homeowners look for a single system that handles both heating and cooling year-round. A modern heat pump can perform well even in colder climates, and paired with a gas furnace in a dual-fuel setup, it covers the full Illinois temperature range efficiently. For additions, sunrooms, or rooms without existing ductwork, ductless mini-split systems offer a flexible and effective alternative. We assess your home, explain what will work best for your situation, and handle the full installation.
Cook County summers bring persistent humidity that makes a properly cooled home feel damp and uncomfortable. A whole-home dehumidifier integrates directly with your existing HVAC system and manages moisture levels automatically, without the hassle of emptying portable units room by room. Humidity control pairs naturally with air filtration and indoor air quality upgrades like whole-home air purifiers and UV air purifier systems, giving you cleaner, more comfortable air all season long.
Thermostat issues are more common than most people expect. A thermostat that is not reading correctly, not responding, or simply outdated can throw off your whole system. We handle thermostat replacement and smart thermostat installation, including Nest, Ecobee, and programmable models, so your system runs on your schedule and responds the way you expect.
Leaking or poorly sealed ductwork is one of the most overlooked sources of comfort problems. If certain rooms never seem to reach the right temperature, or your system runs longer than it should, duct leaks are a likely culprit. We perform HVAC duct inspections, duct leak repair, ductwork sealing, and full ductwork replacement where needed. Fixing the ducts often makes the whole system perform better without touching the equipment itself.
Indoor air quality rounds out the picture. Air filtration installation, air scrubbers, whole-home humidifiers, and HVAC air filter service all contribute to how your system performs and how the air in your home actually feels. All of it comes with no-pressure estimates, priced up front. Give us a call and we'll get the comfort back.
No heat. No cool. System down. We respond fast, and we are available same-day and after hours for urgent calls. Emergency furnace repair, emergency AC repair, and heat pump failures all get the same priority treatment. Real technicians. Real pricing. Real fast response.
If your system goes down and you need help now, call (224) 539-2898 for same-day or emergency service.
Getting your comfort back is easier than you think, and the best way to stay ahead of problems is a tune-up before the season starts. A spring AC tune-up gets your cooling system ready before the heat arrives. A fall furnace tune-up catches issues before the first cold snap. Each visit covers inspection, cleaning, performance checks, and filter evaluation so your equipment is running at its best when you need it most.
We handle commercial HVAC maintenance alongside residential, keeping office buildings, retail spaces, and multi-unit properties on a schedule that works for their operations. Consistent maintenance is the most reliable way to avoid emergency calls, extend equipment life, and keep energy costs in check. One ring and we're rolling.
AC repair cost, furnace repair cost, HVAC replacement cost, heat pump installation cost. These are real questions, and we answer them directly. When you call, we talk through what you are dealing with, schedule a visit, and give you a clear price before any work begins. No vague estimates, no surprise line items after the fact.
The owners are right here, so you get answers on the spot. This is a locally owned business, and when you call, you reach someone who knows Palatine and can speak to your situation directly. We take that accountability seriously on every job. Good workmanship. Good pricing. Good technicians.
Clear communication from the first call to the final test is how we operate, and it is what keeps customers coming back and referring their neighbors.
Palatine is our home base, and we serve residential and commercial customers throughout the northwest suburbs. Our regular service area includes Rolling Meadows, Arlington Heights, Schaumburg, Hoffman Estates, Inverness, and Barrington, along with the broader Cook County communities in between. Whether you are a homeowner, a landlord managing a rental property, or a business owner keeping a commercial space comfortable, we cover the area and we know the local climate well. One call, and a technician is on the way.
We work with both residential and commercial customers throughout Palatine and the surrounding area.

Yes, same-day availability is something we offer for both repairs and emergency calls. If your system goes down and you need help quickly, call (224) 539-2898 and we will work to get a technician out the same day. Emergency no-heat and no-cool situations get priority scheduling.
Response time depends on the day and current call volume, but we move quickly on urgent situations. When you call, we will give you an honest estimate of when to expect a technician. Same-day visits are available for breakdowns and emergency calls throughout Palatine and the surrounding communities.
For most repair and service calls, yes, someone should be present so the technician can access the equipment and walk you through the findings before any work begins. If you are a property manager arranging service for a tenant's unit, let us know when you call and we can work through the access details together.
It helps to clear a path to the furnace or air handler and make sure the outdoor condenser is accessible. Removing stored items from around the equipment before we arrive lets the technician get started right away without delays. If access is limited or the equipment is in a tight space, just mention it when you call so we can plan accordingly.
Absolutely, and we encourage it. Knowing which rooms are too hot, too cold, or getting weak airflow gives the technician useful context before the inspection begins. The more specific you can be about what you have noticed, the faster we can trace the cause.
We explain what we find before any work begins, and we stay in communication throughout the visit. If something unexpected comes up during the repair, we stop and talk it through with you before moving forward. Clear communication from the first call to the final test is how we operate on every job.
A standard repair visit usually runs one to two hours, depending on the system and the nature of the problem. A full system replacement takes longer, typically a half day or a full day depending on the scope of the work. We will give you a realistic time estimate when we schedule the visit.
System size and equipment type do affect pricing, particularly for installation and replacement jobs. A larger home or a more complex system requires appropriately sized equipment, which factors into the overall cost. We walk through all of that with you upfront so the quote reflects your actual situation before any work begins.
Wise-Air Heating, Air Conditioning and Refrigeration handles the full range of residential and commercial heating and cooling work, from a furnace repair on a cold January morning to a full AC system replacement before summer, to emergency service when a system goes down at the worst possible time.

| System Service | What It Covers | When You Need It | Good to Know |
|---|---|---|---|
| Heat Pump Repair & Service |
| homes running a heat pump as the primary heating and cooling source, including dual-fuel setups | Heat pumps handle both heating and cooling, so a problem in one mode often points to a component shared by both. A thorough diagnostic covers the full system, not just the symptom. |
| Heating & Furnace Repair |
| any home or building that has lost heat or is heating unevenly during Illinois winters | A furnace that starts and shuts off repeatedly is often signaling a safety or airflow issue. Getting it diagnosed before temperatures drop hard saves time and discomfort. |
| Full System Installation & Replacement |
| homeowners replacing aging or failing equipment and anyone upgrading to a more efficient system | Replacing a furnace and AC together as a matched system often delivers better efficiency and a longer service life than replacing one while the other ages out a season later. |
| Furnace & AC System Replacement |
| homeowners with equipment approaching 15 to 20 years, frequent breakdowns, or rising energy bills | Illinois winters and summers both push HVAC equipment hard. Replacing aging furnace and AC units together as a system often makes more financial sense than repairing one while the other fails the next season. |
| Thermostat & Smart-Control Installation |
| homeowners who want better control over comfort and energy use without upgrading the whole system | A thermostat that reads incorrectly or does not respond can make a perfectly good HVAC system behave as if something is broken. It is often the first thing worth checking. |
| Emergency HVAC Service |
| any situation where a system has failed and waiting is not an option | We prioritize no-heat and no-cool calls, especially during extreme weather. When you call, we give you an honest estimate of when to expect a technician. |

| homes with rooms that never reach the right temperature or systems that run longer than expected | Leaking ducts can push conditioned air into attics and crawl spaces rather than living areas. Sealing them often improves comfort and lowers energy bills without touching the equipment. |
| Whole-Home Dehumidification & Humidity Control |
| Cook County homeowners dealing with persistent summer humidity that makes a cooled home feel damp and uncomfortable | A whole-home dehumidifier works automatically through your existing system, eliminating the need to empty portable units room by room. It pairs well with air filtration upgrades for overall indoor comfort. |
| Heat Pump Installation |
| homeowners looking for a single system that handles both heating and cooling, or adding comfort to a room without existing ductwork | A modern heat pump paired with a gas furnace in a dual-fuel setup covers the full Illinois temperature range efficiently. We assess your home and explain what will work best before any equipment is ordered. |
| AC Repair & Service |
| homeowners and businesses with a central air system that stopped cooling or will not turn on | Most AC failures in the Chicago area happen during the first heat wave of summer, when systems run hardest after months of sitting idle. Scheduling a diagnostic early in the season helps avoid the busiest call windows. |
How do I know if my furnace or AC needs to be replaced rather than repaired?
Age and repair history are the two biggest factors. A furnace or air conditioner pushing 15 to 20 years, one that has needed multiple repairs in recent seasons, or one running well below its rated efficiency is usually a replacement candidate. We walk through the numbers with you honestly so you can make a confident decision. If a repair makes more sense, we say so.
Why did my system stop heating or cooling even though it was running fine?
A system that stops heating or cooling without warning can point to several causes: a refrigerant leak, a failed capacitor, a tripped limit switch, a dirty coil, or a controls issue. In some cases a clogged filter is enough to shut the system down. A diagnostic visit covers the full system so we find the actual cause rather than guessing.
How often should I schedule maintenance and tune-ups?
Twice a year is the standard recommendation: once in spring before cooling season starts and once in fall before heating season begins. Each visit covers inspection, cleaning, and performance checks so your equipment is ready when the weather changes. Consistent maintenance is the most reliable way to extend equipment life and avoid unexpected breakdowns.
Same-Day and Emergency Availability
No heat and no cool situations get priority. We are available same-day and after hours for urgent calls throughout Palatine and the surrounding northwest suburbs.
What does a seasonal tune-up actually cover?
A tune-up is a working inspection, not just a visual check. We inspect and clean the system, evaluate the filter, check refrigerant levels on cooling equipment, test ignition and heat exchanger components on heating equipment, and run through the controls to confirm everything is performing within normal range. If we find something worth addressing, we explain it before any additional work is done.
Why is one room always hotter or colder than the rest of the house?
Uneven temperatures usually come down to one of three things: duct leaks routing conditioned air away from the room, an airflow imbalance in the duct system, or an equipment sizing issue. A duct inspection can identify leaks and sealing opportunities, and an airflow evaluation can point to balancing adjustments. Fixing the ductwork often solves the problem without touching the equipment itself.
What do strange noises from my HVAC system mean?
The type of noise usually points toward the cause. Banging or clanking can indicate a loose or broken component inside the unit. Squealing often points to a belt or motor bearing. Clicking at startup is normal, but clicking that continues during operation can signal a controls or ignition issue. If you hear something that was not there before, it is worth a call before the problem gets larger.
Upfront Quotes With No Surprise Fees
We give you a clear price before any work begins and we do not move forward until you have approved it. What we quote is what you pay.
Should I choose a heat pump or a furnace for my Palatine home?
Both are solid options depending on your home and priorities. A heat pump handles heating and cooling from one system and can be very efficient in moderate cold. For the full Illinois winter, a dual-fuel setup that pairs a heat pump with a gas furnace covers the whole temperature range efficiently. We assess your home, your current setup, and your goals and explain which direction makes the most sense before you commit to anything.
How do ductwork leaks affect my energy bills?
Leaking ducts push conditioned air into unconditioned spaces like attics, crawl spaces, and wall cavities rather than into the rooms you are trying to heat or cool. The system runs longer to compensate, which raises energy costs without improving comfort. Sealing the ductwork keeps the conditioned air where it belongs and often reduces runtime and energy use noticeably.
Work Performed by Qualified HVAC Technicians
Every job is handled by trained technicians who know residential and commercial HVAC systems. We stand behind every system we service.
How does same-day and emergency service work?
When you call for an emergency or same-day appointment, we work to get a technician out as quickly as possible. No-heat and no-cool situations get priority scheduling, especially during extreme weather. When you call, we give you an honest estimate of arrival time based on current availability. We do not leave you guessing.
How does pricing and the estimate process work?
When you call, we talk through what you are dealing with and schedule a visit. The technician diagnoses the system, explains what was found, and gives you a clear price before any work begins. We do not start work until you have approved it. There are no vague estimates and no surprise line items after the fact.
How long does a full system replacement take?
A standard furnace or AC replacement typically takes a half day to a full day depending on the scope of the work, the equipment involved, and site conditions. A more complex installation, such as adding ductwork or converting to a different system type, may take longer. We give you a realistic time estimate when we schedule the job so you can plan accordingly.
Every situation is a little different, so call us at (224) 539-2898 and we will talk through your system, your options, and what makes sense for your home or building.
