One call gets the whole thing moving.
Every home's heating and cooling setup tells a different story, and the same is true for commercial properties. An older ranch with a single-zone furnace needs a different conversation than a multi-unit building with rooftop equipment. We handle the full range of residential and commercial heating and cooling work: AC repair, furnace repair, heat pump service, full system replacement, ductwork, thermostat upgrades, indoor air quality, seasonal maintenance, and emergency calls.
When you call, the rate is explained before anything is scheduled. You hear what the visit covers and what it costs. We give honest recommendations on repair versus replacement, never an upsell.
Reach out and we'll work out what it needs.
A system that is not cooling, blowing warm air, freezing up, short cycling, making unusual noise, leaking water, or failing to turn on at all is telling you something. The visit covers a full diagnosis, refrigerant leak check, and inspection of the condenser and evaporator coils. Seasonal AC maintenance and tune-ups are also available if you want to get ahead of the summer heat rather than react to it. AC repair cost is explained on the call.
No heat, cold air blowing from the vents, a furnace making grinding or rattling sounds, or a unit that simply will not start are all common calls we take in Wheaton. The visit covers a heat exchanger check, ignition and burner inspection, and an airflow assessment to make sure the system is moving heat the way it should. Annual furnace maintenance is available to catch small problems before they become large ones. Furnace repair cost and replacement cost are both explained on the call.
A heat pump that is not heating, not cooling, running constantly, or short cycling needs a careful look at the refrigerant charge, reversing valve operation, defrost cycle, and coil condition. Heat pumps run year-round in both directions, so wear patterns differ from a standard AC or furnace. Tune-up and maintenance visits are available. Heat pump repair cost is explained on the call.
A thermostat that is not responding, reading the wrong temperature, or simply too old to communicate with modern equipment affects comfort in every room. We install programmable and smart thermostats, and we can set up zoning controls that let different parts of a home or building run at different temperatures. Smart thermostat cost is explained on the call.
Leaking ducts waste conditioned air before it reaches the rooms that need it. Uneven temperatures from one end of a house to the other, or weak airflow from certain registers, often trace back to duct problems rather than the equipment itself. We handle duct sealing and ductwork replacement, with airflow balanced rather than left to chance. Ductwork repair cost is explained on the call.
Air filtration systems, whole-home air purifiers, and air scrubbers all address what circulates through the system every time it runs. If the air feels stale, dusty, or irritating, or if humidity is making the space uncomfortable, there are solutions that integrate directly with the existing HVAC system. Air quality improvements and humidity control work together, and the right approach depends on what the home or building actually needs.
A tune-up covers coil cleaning, filter check, refrigerant level, electrical connections on the unit, and blower and air handler inspection. Catching a worn capacitor or a dirty coil before the hottest or coldest week of the year is a better situation than dealing with a breakdown during it. HVAC maintenance cost is explained on the call.
We'll get your home comfortable again fast.
Systems around here run into the same few faults, and some of them hit at the worst possible time. No heat on a January night, no cooling during a July heat wave, a system that was running fine one day and completely silent the next. We take emergency calls every day from 7:00 AM to 11:00 PM. When you call, the scope of the problem is discussed on the phone and the price is confirmed before anything is scheduled.

We protect your home. We service your system. We earn the call.
DuPage County runs through genuine four-season weather. Winters are cold enough to put real demand on heating equipment, and summers bring heat and humidity that test cooling systems just as hard. Wide seasonal swings mean the furnace and the air conditioner both earn their keep, and the moisture that builds up in July and August adds a layer of comfort work that milder climates never deal with. The three services below come up regularly in this area for good reason.
At some point, repair stops making sense. A system that has reached the end of its useful life, broken down more than once in a season, or lost enough efficiency to show up on the utility bill is a candidate for replacement rather than another repair visit. A full HVAC system replacement covers equipment selection sized to the home or building, removal of the old unit, and installation of the new system. We handle the install and the permits.
Both new HVAC system installation and central air installation are available. Replacement cost and installation cost are explained on the call.
Let us handle the install and the permits.
A heat pump handles both heating and cooling from a single system, which makes it a practical choice for DuPage County homes that want to reduce reliance on gas heat without giving up winter performance. Modern cold-climate heat pumps hold efficiency well into lower temperatures, and the efficiency gains in the moderate shoulder seasons are meaningful. We size and install new heat pump systems, and ductless mini-split installation is available for additions, older homes without ductwork, or spaces that need independent temperature control. Heat pump installation cost is explained on the call.
Wheaton summers bring outdoor humidity that works its way indoors. The result is air that feels sticky even when the thermostat says the temperature is fine, along with musty odors, condensation on windows, and moisture that makes the cooling system work harder than it needs to. A whole-home dehumidifier integrates with the existing HVAC system and pulls moisture out of the air as it circulates through the ductwork, covering every room rather than just the one where a portable unit sits.
Getting the diagnosis right is what the visit is for. The right equipment and the right settings depend on the home's layout, the existing system, and what the space is actually experiencing.
For homeowners and property managers who want it done right, the scope of the job matters as much as the price. Commercial properties have their own demands: rooftop units, multi-zone systems, equipment that runs longer hours and serves more people. Commercial rooftop units are covered as well as residential, including RTU repair, office HVAC repair, and HVAC service for small businesses and multi-unit buildings.
Commercial HVAC installation, replacement, and maintenance are all available. Cost is explained on the call before anything is scheduled.
Reach out and we'll work out what it needs.
Wheaton is home base, and we take calls from across the county. Nearby communities we serve regularly include Carol Stream, Winfield, Warrenville, Glen Ellyn, Lombard, West Chicago, Naperville, and Lisle. Residential and commercial calls are both welcome. If you are in the area and need heating or cooling work handled, call to confirm coverage and get a price.
Some homes need a full system replacement. Others just need a tune-up. The price you get reflects what the visit actually covers, and you hear it before anything is scheduled.
Common cost questions we hear: what does AC repair cost, what does furnace repair cost, what does a heat pump repair run, what does HVAC installation or replacement cost, what does a thermostat swap cost, what does duct sealing cost, what does an HVAC tune-up cost. Ask what it covers and you get a straight answer. The rate is given on the call, the scope is explained, and you decide from there.
We give honest recommendations on repair versus replacement, never an upsell. If a repair makes more sense than a replacement, that is what we say.
One call gets the whole thing moving.
We handle heating and cooling work for homes, rental properties, and commercial buildings throughout Wheaton and DuPage County. That includes single-family homes, condos, townhomes, office buildings, retail spaces, and multi-unit properties. Commercial rooftop units are covered as well as residential systems, so property managers and building owners can use the same number as homeowners.
Call (331) 296-4956 and we will confirm what the job involves and what it costs.
We cover Wheaton and the surrounding communities throughout DuPage County, including Glen Ellyn, Winfield, Carol Stream, Warrenville, Naperville, Lisle, Lombard, and West Chicago.
If you are unsure whether your address falls within our service area, call (331) 296-4956 and we will confirm coverage before anything is scheduled. Residential and commercial calls are both welcome across the area.
When you call (331) 296-4956, someone who knows the trade picks up and can scope the job on the phone.
We are available every day from 7:00 AM to 11:00 PM, including weekends. You get a straight answer on what the visit covers and what it costs before anything is booked.
The price is confirmed before the visit is scheduled, not after the work is done. We scope the job on the call, explain what the visit covers, and give you a rate before anyone comes out. You decide whether to proceed from there, with no obligation to book before you have a price.
The price covers the diagnosis and the work discussed on the call. We explain what the visit includes before it is scheduled so there is nothing to figure out after the fact. If the technician finds something additional during the visit, that gets explained and priced separately before any extra work is authorized.
Cost depends on the type of equipment, the nature of the fault, and the extent of the work involved. A refrigerant recharge, a thermostat swap, a furnace igniter replacement, and a full system replacement each carry a different price, and the rate is given on the call after the job is scoped.
Call (331) 296-4956 and describe what the system is doing, and we will give you a price before anything is scheduled.
If the technician finds additional faults during the visit that were not apparent on the call, those are explained and priced before any extra work begins. Factors that can affect cost include the age of the equipment, whether parts need to be sourced for an older system, and the scope of ductwork or wiring involved in an installation. Nothing is added without your agreement first.
Older homes in Wheaton often have systems that were sized for a different era of insulation and window standards, and aging equipment can present faults that newer systems do not. We work on older furnaces, aging central air systems, and original ductwork, and we give honest guidance on whether repair or replacement makes more sense given the equipment's condition and age.
Call (331) 296-4956 and describe what the system is doing.
Property managers and landlords with multiple units in Wheaton or elsewhere in DuPage County are welcome to call for both routine maintenance and urgent repairs across their properties. We handle commercial and multi-unit HVAC calls the same way we handle residential ones: the job is scoped on the call, the price is confirmed before the visit, and the work is explained from start to finish.
Call (331) 296-4956 to discuss what your properties need.
A diagnostic and repair visit for a common fault, a failed igniter, a refrigerant issue, or a tripped pressure switch, typically takes one to two hours depending on the equipment and what the inspection turns up. A full system replacement takes longer and the timeframe is discussed when the job is scoped. We give you a realistic picture of what the visit involves before it is booked.
Call (331) 296-4956 as soon as you know and we will work out a new time.
We are available every day from 7:00 AM to 11:00 PM, so there is flexibility in finding a slot that works. The price and scope confirmed on the original call carry over to the rescheduled visit.
The diagnosis is explained on every call, and the person who does the work walks you through what was found and what was done before leaving the property. If parts were replaced or adjustments made, those are noted so you have a clear picture of the work. Any follow-up recommendations are explained at the same time.
When the job is done, we leave your home clean and comfortable, and the work is explained from start to finish. We serve residential and commercial customers throughout Wheaton and DuPage County, and we are available every day from 7:00 AM to 11:00 PM.

Dependable service. A price agreed before we start. Local HVAC know-how.
Every home and building in Wheaton puts different demands on its heating and cooling system, and the right service depends on what the system is actually doing. We cover the full range of HVAC work across DuPage County, from a single repair call to a complete system replacement. The table below lays out what each service covers, who it fits best, and what is worth knowing before you call. Reach out and we will scope the job on the phone before anything is scheduled.
| HVAC Service | What It Covers | Common Needs | What to Keep in Mind |
|---|---|---|---|
| Full System Installation & ReplacementMost Popular | Old equipment removalLoad calculation and proper sizingInstallation to manufacturer specificationsPermit handling for the job | Homes or buildings where the system is at end of life, needs frequent repairs, or has lost significant efficiency | Sizing matters more than brand. An oversized AC short-cycles and leaves humidity behind. An undersized furnace runs constantly and still falls short on the coldest nights. |
| Seasonal Maintenance & Tune-Ups | Filter, coil, and refrigerant checkElectrical connection inspectionAirflow measurement through supply and returnFull system cycle confirmation | Homeowners and property managers who want to catch small problems before they become emergency calls | Scheduling a tune-up before the heating or cooling season starts is the most practical way to avoid a no-heat or no-cool call when the system is working hardest. |
| Emergency HVAC Service | Fast response for heating and cooling failuresPhone diagnosis before dispatchNo-heat and no-cool calls coveredAvailable every day 7:00 AM to 11:00 PM | Homes or buildings where the system has stopped working entirely and conditions are becoming uncomfortable | We scope the problem on the phone before anything is dispatched, so the visit is prepared for what the system is actually doing rather than arriving cold. |
| Whole-Home Dehumidification & Humidity Control | Whole-home dehumidifier installationIntegration with existing air handler and ductworkHumidity level assessment for the homeReturn air and condensate connection | DuPage County homes where high summer humidity makes a properly cooled house feel warmer and stickier than the thermostat reads | A whole-home unit pulls air through the existing duct system and returns conditioned air throughout the house, so there is no separate unit to empty or move room by room. |
| Heat Pump Repair & Service | Reversing valve and refrigerant checkDefrost cycle inspectionHeating and cooling mode confirmationDiagnosis before repair recommendation | Homes with a heat pump that has stopped heating in winter or cooling in summer | A heat pump that runs but fails to heat in cold weather often has a defrost or refrigerant issue, not a full system failure. The diagnosis determines the repair path. |
| Heating & Furnace Repair | Heat exchanger and burner inspectionIgnition system checkBlower motor and airflow reviewShort-cycle and no-heat diagnosis | Homes with a furnace that won't start, blows cold air, or cycles without heating | Illinois winters move fast. A furnace that shows early warning signs in October is worth having checked before January temperatures arrive. |
| Indoor Air Quality & Air Filtration | Whole-home air filtration installationMedia filter and air purifier integrationHumidity assessment for the homeConnection to existing HVAC system | Homes dealing with dust, allergens, persistent stuffiness, or elevated humidity during DuPage County summers | A whole-home filtration system integrates with the existing air handler and ductwork, so it conditions every room rather than just the one where a portable unit sits. |
| AC Repair & Service | Refrigerant level and pressure checkCondenser and evaporator coil inspectionAirflow check through the full systemDiagnosis explained before repair is authorized | Homes with an AC that blows warm air, short-cycles, or shuts off without explanation | Catching a refrigerant or airflow problem early usually costs less than waiting until the system stops cooling entirely during a DuPage County heat stretch. |
| Ductwork Repair & Sealing | Duct system inspectionLeak and disconnection identificationSealing or repair of affected sectionsAirflow confirmation after work | Homes with rooms that stay warm when the rest of the house cools, or cold spots that persist regardless of runtime | Leaking ducts can lose a significant portion of conditioned air before it reaches the living space, which raises energy use without improving comfort. |
| Thermostat & Smart-Control Installation | Compatibility check with existing air handler and wiringThermostat replacement or smart-control upgradeCalibration and setpoint confirmation | Homes where the thermostat reads incorrectly, fails to trigger the system, or is not compatible with new equipment | A thermostat problem can look exactly like an equipment failure. We confirm compatibility before the new unit goes in so the install does not create a second issue. |
| Heat Pump Installation | Cold-climate equipment selection for Illinois wintersDual-fuel configuration with existing gas furnaceRefrigerant line set and low-voltage control wiringHeating and cooling mode setup and confirmation | Wheaton homes transitioning away from a gas-only system or adding a heat pump for efficiency gains in moderate weather | Modern cold-climate heat pumps operate efficiently well below freezing. A dual-fuel setup keeps the gas furnace as a backup for the coldest stretches without giving up efficiency the rest of the year. |
