Palatine HVAC Company handles heating, cooling, and air quality work for homes and commercial properties across Palatine and Cook County. From a furnace that stops mid-January to a central AC that quits on the hottest week of the summer, we are the call that gets the job moving. We work with homeowners, landlords, property managers, and business owners, and we cover the full range of HVAC work: repair, installation, maintenance, and everything in between.
Heat restored. Cooling dialed in. Comfort back.
From a quick tune-up to a whole-system replacement, the diagnosis comes first, and the price follows before anything is scheduled. We cover AC repair, furnace repair, heat pump service, ductwork, thermostats, indoor air quality, and seasonal maintenance. Whether the call comes from a homeowner in a single-family house or a property manager running a multi-unit building, the process is the same: we look at the system, identify the problem, and give you the repair or install scope priced before the work starts.
That applies to every job, small or large. A refrigerant leak, a cracked heat exchanger, a blower motor that is drawing too much current, a duct run that has been losing conditioned air for years: each one gets properly diagnosed before a repair is recommended. We work on all major equipment brands and handle both residential and light commercial systems throughout the Palatine area.
When the AC stops cooling or stops running entirely, the causes range from a tripped float switch on a clogged condensate line to a failed compressor or a refrigerant leak at the evaporator coil. The technician who comes out will check the system from the air handler to the condenser before anything is quoted. Common calls include an air conditioner not cooling to setpoint, a unit that runs constantly without dropping the temperature, a condenser that cycles on and off, and a central AC that simply will not turn on.
Refrigerant diagnosis is part of the visit when the symptoms point that way. Condenser coil condition, evaporator coil condition, blower performance, and filter restriction all get checked when the situation calls for it. AC tune-ups and pre-season maintenance visits are available for customers who want the system confirmed before summer arrives rather than after it has already failed.
One call is all it takes to get it looked at.
A furnace that is not heating, a heater that runs but does not warm the house, a burner that ignites and then shuts off: these are the calls that come in once Cook County temperatures drop and a system that was borderline in October becomes a problem in December. The visit covers ignition components, heat exchanger condition, gas valve operation, inducer motor performance, and the controls that tell the system when and how to run.
We treat your home and its system the way we would our own. That means the furnace gets checked thoroughly before a repair is recommended, and a replacement conversation only happens when the repair math genuinely does not work in the customer's favor. Furnace tune-ups and pre-season inspections are available in the fall, and furnace replacement is handled when the equipment has reached the end of its useful life or when efficiency gaps make continued repair the wrong call.
A heat pump runs both heat and cool from a single outdoor unit, which makes it a practical option for a Palatine home that needs year-round comfort control without separate systems. When a heat pump is not heating in winter or not cooling in summer, the diagnosis follows the refrigerant circuit, the reversing valve, the defrost controls, and the air handler. Many heat pump problems are misdiagnosed because the system behaves differently in heating mode than in cooling mode, and the visit accounts for that.
Ductless mini-split installation and repair are also part of what we do. Mini-splits work well in additions, converted spaces, and rooms that the main duct system does not reach effectively. We handle installation of new mini-split systems and repair of existing units, including refrigerant issues, control board failures, and drainage problems.
Whether this is your first HVAC repair or your tenth, a thermostat problem can look like a system problem until someone checks the controls. A thermostat that is not reading temperature accurately, not communicating with the air handler, or not switching between heating and cooling modes correctly will run the equipment the wrong way no matter how well the mechanical side is working.
We install programmable thermostats, smart thermostats, and Wi-Fi-enabled controls that let a homeowner or property manager adjust schedules and monitor the system remotely. Zoning systems, which divide a building into independently controlled temperature areas, are also available where the ductwork and equipment support them. Pick up the phone and we'll get started.
Leaky ductwork is one of the most common reasons a house heats or cools unevenly, and it is also one of the most commonly overlooked. When one room is always too hot or too cold, the cause of an uneven house actually investigated rather than assumed. That means checking static pressure, supply and return balance, duct condition, and whether the equipment is sized correctly for the load it is being asked to carry.
Duct sealing and duct repair address gaps, disconnected runs, and sections of ductwork that have deteriorated over time. Beyond the ductwork itself, indoor air quality work includes whole-home air filtration installation, air purifier and air scrubber installation, and HVAC filter upgrades that improve what the system puts back into the living space. For homes where allergens, dust, or odors are a persistent issue, the air quality side of the system is worth addressing alongside the mechanical side.
Making comfort simple is most of what the job is, and that matters most when the system goes down at the wrong time. No heat in the middle of a northern Illinois winter and no cooling during a July heat wave are the two calls that cannot wait. We take emergency HVAC calls every day from 6:30 AM to 9:30 PM, and that covers furnace emergencies, AC emergencies, heat pump failures, and any situation where the system is down and the house is not livable.
When you call, you reach someone who can scope the problem on the phone and confirm what the visit covers. We do not promise an arrival time, but emergency calls are answered and prioritized within our daily service window.
Property managers and building owners have different needs than a single homeowner: a system failure in a commercial space affects tenants, customers, or employees, and a replacement decision involves capital planning, not just a repair estimate. We handle commercial HVAC repair, commercial AC repair, commercial furnace repair, and commercial heat pump service for buildings of all types in and around Palatine.
Commercial HVAC installation is available for new construction, buildouts, and full system replacements. Second opinions on replacement quotes welcomed. If another contractor has recommended a full system replacement and you want the diagnosis confirmed before committing, that is a reasonable call to make.
Dealing with a furnace that won't keep up or an AC that can't cool is a worse problem in July or January than it is in April or October, which is why seasonal maintenance exists. A furnace tune-up in the fall and an AC tune-up in the spring catch the issues that would otherwise surface at the worst possible time. Heat pump maintenance covers both modes, since a heat pump that has not been serviced heading into winter may run in heating mode without the efficiency or capacity it should have.
A system check ends with the readings reviewed with you. That means the measurements taken during the visit are explained, not just filed away, and any issues found are described in plain terms before a repair is recommended. Heating checked. Cooling checked. Airflow measured.
Cook County sits in a true four-season climate, with winters cold enough to push gas furnaces hard and summers humid enough to make a well-functioning AC essential. The work that comes up most often here reflects that: full system replacements, heat pump installations as homeowners weigh their options, and whole-home humidity control for the months when outdoor air brings moisture indoors. The three services below are the ones most shaped by this region's conditions.
Illinois winters put real hours on heating equipment, and when a furnace reaches the point where repair costs are stacking up or the system can no longer hold temperature on the coldest nights, replacement becomes the practical answer. The same applies to aging central AC units that struggle through August. A full system replacement visit starts with confirming the existing equipment's condition, sizing the new system correctly for the home, and walking through the options before any work is scheduled. We handle furnace replacement, AC replacement, and full HVAC system replacement as a paired job when both units are at end of life.
Heat pump adoption is growing in the Palatine area as homeowners look for a single system that handles both heating and cooling. A heat pump installation typically connects to existing ductwork, which keeps the job scope manageable for most homes. The installation covers the outdoor unit, the air handler, the refrigerant connections, and the controls. We discuss the equipment options on the call so the customer understands what they are getting before the job is scheduled.
Cook County summers bring outdoor humidity levels that push into the home even when the AC is running. High indoor humidity makes the house feel warmer than it is, contributes to condensation on windows and surfaces, and affects air quality over time. A whole-home dehumidifier installs as part of the existing HVAC system, treating the air as it passes through rather than running a standalone unit in a single room. We handle dehumidifier installation and connect it to the existing equipment and controls.
When you call, you get a price before anything is scheduled. The rate is confirmed on the call, what the visit covers is explained, and any questions about cost get a straight answer. There is no commitment required to ask what a diagnostic visit costs, what a tune-up runs, or what a replacement estimate involves.
If you have already received a replacement quote from another contractor and want a second opinion, that is a straightforward request. Know the price. Know what the visit covers. Know what comes next.
We will look at the system and tell you what it needs.
We serve Palatine and the surrounding communities throughout Cook County and the northwest suburbs. That includes Arlington Heights, Schaumburg, Hoffman Estates, Rolling Meadows, Buffalo Grove, and Inverness. Whether the call comes from a homeowner, a landlord managing a rental property, or a business owner with a commercial building, the service area covers the full northwest Cook County corridor.
We handle the full range of heating and cooling work, from a furnace that will not fire on a January morning to an AC that cannot keep up during a July heat wave. That includes repairs, full system replacements, heat pump service, ductwork, thermostats, indoor air quality, and seasonal maintenance. We work on both residential properties and light-commercial buildings across Palatine and Cook County. If you are not sure whether what you are dealing with falls in our scope, call and describe the situation and we will tell you.
Yes. We are available every day of the week, including Saturday and Sunday, from 6:30 AM to 9:30 PM. That covers both scheduled service visits and urgent calls when the system is down and the timing is not convenient.
If you need a furnace checked on a Sunday morning or an AC looked at on a Saturday afternoon, call (224) 539-2898 and we will confirm what the schedule allows.
Start by checking the thermostat settings and the filter, since a clogged filter can trip a safety switch and shut the system down entirely. Check the breaker for the air handler and the outdoor unit as well, since a tripped breaker is sometimes the whole problem. If none of those restore operation, call us and describe what the system was doing before it stopped. We will scope the diagnostic on the call and confirm what the visit covers before anyone comes out.
Yes. We service light-commercial HVAC systems across Palatine and the surrounding Cook County area, including rooftop units, split systems, and building heating and cooling equipment. Property managers and business owners call us for repairs, seasonal maintenance, and full system replacement when the equipment has reached the end of its useful life. The process is the same as on the residential side: we diagnose the problem, confirm the scope, and price the work before anything is scheduled.
Weak airflow from the registers, warm air coming from the vents when the AC is running, a system that short-cycles or runs constantly without reaching the set temperature, and unusual noises like banging, rattling, or squealing during a cycle are all signs that something is wrong and getting worse. A burning smell from the furnace or a sulfur odor near gas equipment should be treated as urgent. Call right away if you notice either of those, and step outside while you do. For the other symptoms, the sooner the system is looked at, the less likely a small problem becomes a larger repair.
When you call, we scope the job with you on the phone and confirm what the visit covers before scheduling. We take short-notice work when the system is down and the situation is urgent, and we take emergency calls every day within our service hours of 6:30 AM to 9:30 PM. We do not promise a specific arrival window, but we confirm what is available when you call so you know what to expect.
Call (224) 539-2898 and we will work through the scheduling with you.
We serve Palatine and the surrounding communities across Cook County and the northwest suburbs, including Arlington Heights, Rolling Meadows, Schaumburg, Hoffman Estates, Inverness, Buffalo Grove, and Barrington. Call and give us your address and we will confirm coverage and any applicable service-call rate before scheduling. The rate is confirmed on the call so there is nothing to figure out after the fact.
The scope and the price are confirmed before the work starts, so you know what you are agreeing to before anyone comes out. Payment timing is covered on the call when the job is priced. We do not schedule work without first confirming the rate and what the visit includes, so there is no ambiguity about cost when the job is done.
Deposit requirements depend on the scope of the job and are covered when the work is priced on the call. For a full system replacement, the scope, the equipment, and the total cost are all confirmed before anything is scheduled, and any deposit requirement is part of that conversation. Call and describe the situation and we will walk through the details with you.
Yes, system size and property type both affect what a repair or replacement costs. A larger system has more components to inspect, and a replacement job is priced based on the equipment selected and the scope of the installation. When you call, we go through the system details with you and give you a price that reflects the actual job, not a flat figure that changes when someone arrives. The rate is confirmed before anything is scheduled.
Palatine HVAC Company takes calls every day from 6:30 AM to 9:30 PM. Whether the system needs a repair, a tune-up, a full replacement, or an urgent emergency visit, the call is the place to start. You get a price on the phone, you find out what the visit covers, and you decide from there.
Heat restored. Cooling dialed in. Comfort back.

From a furnace that quit overnight to an AC that can't keep up through a Chicago-area summer, we handle the full range of residential and commercial heating and cooling work in Palatine and across Cook County. Every visit starts with a diagnosis, and the price is confirmed before any work is scheduled. The table below covers what each service includes, who it fits, and what is useful to know before you call.
| Service Type | What It Covers | When You Need It | What to Keep in Mind |
|---|---|---|---|
| Thermostat & Smart-Control Installation |
| Anyone upgrading from a manual thermostat or replacing a unit that is not communicating correctly | A thermostat that reads temperature incorrectly or fails to switch modes is sometimes a wiring issue rather than the thermostat itself. We check both before recommending a replacement. |
| Ductwork Repair & Sealing |
| Homes with uneven temperatures or rooms that never reach the set temperature | Duct leaks that lose conditioned air into wall cavities or the attic force the system to run longer than it should. Sealing addresses the leak directly rather than masking the symptom. |
| Whole-Home Dehumidification & Humidity Control |
| Homes that feel clammy or show condensation even when the AC is running | An oversized AC that short cycles can hit the temperature setpoint without pulling meaningful moisture from the air. The fix depends on whether the cause is the equipment size, a duct issue, or both. |
| Heating & Furnace Repair |
| Anyone with a furnace blowing cold air, short cycling, or not turning on | A furnace that short cycles or struggles to hold temperature in January is showing wear that tends to get worse the longer it runs that way. |
| Emergency HVAC Service |
| Anyone with a system that has stopped working entirely or is showing a safety concern | We take urgent calls seven days a week from 6:30 AM to 9:30 PM. A burning smell, a sulfur odor near gas equipment, or any carbon monoxide concern warrants a call right away. |
| Heat Pump Repair & Service |
| Homes with an existing heat pump that is not heating or cooling correctly | Defrost cycle faults are commonly misread as compressor failures. Diagnosis before quoting parts matters more on heat pumps than on almost any other equipment. |
| Seasonal Maintenance & Tune-Ups |
| Homeowners who want to catch wear before it becomes a repair call | A tune-up is a good time to find out what a system needs before the heaviest heating or cooling demand of the season arrives. It also gives you a clear picture of how much life the equipment has left. |
| Heat Pump Installation |
| Homeowners replacing aging equipment and weighing a heat pump against a furnace-and-AC setup | Cold-climate heat pump models now carry ratings for sub-zero performance, which changes the comparison for Palatine-area homes that once ruled them out for winter use. |
| Indoor Air Quality & Air Filtration |
| Households concerned about dust, allergens, or air quality in a tightly sealed home | Filtration upgrades work with the existing system and do not require separate equipment. The right filter type depends on the blower capacity, so we check that before recommending a product. |
| Full System Installation & ReplacementMost Popular |
| Homeowners whose system is at end of life or no longer keeping up with the load | Second opinions on replacement quotes are welcomed. If another contractor has recommended replacement, call us and we will look at the system before you commit. |
| AC Repair & Service |
| Homeowners with an AC that won't cool, runs constantly, or has stopped working | Cooling problems often show up on the hottest days when the system is under the most load. Early diagnosis prevents a small fault from becoming a compressor failure. |
Call us at (224) 539-2898 to get a quote, schedule a diagnostic visit, or ask about a second opinion on a replacement. We are available seven days a week from 6:30 AM to 9:30 PM.
