When the furnace stops or the AC can't keep up, the call you need to make is a short one. We cover heating and cooling work across Prospect Heights and the surrounding area: repair, replacement, seasonal maintenance, and the in-between calls that don't fit neatly into a category. You get a price before anything is scheduled, and the visit covers a proper diagnosis before any repair is recommended. That's what the call is for.
Prospect Heights is a town of single-family homes, condos, and smaller commercial buildings, and the heating and cooling work that comes out of it reflects that. Homeowners dealing with a furnace that won't fire in January. Property managers with a tenant who has no cool in July. Business owners whose rooftop unit has started short-cycling. Whatever the situation, we scope it on the call, confirm the price before we schedule, and send someone out who knows what to look for.
Call (224) 539-2898 to get started, and reach us any day from 6:30 AM to 9:30 PM.
A good portion of the housing stock in a town this size was built when equipment sizing was less precise and ductwork was designed around a floor plan that may have changed more than once since. An addition that was tacked on twenty years ago, a basement that was finished after the original duct layout was set, a second floor that never quite reaches the temperature the thermostat says: these are not unusual situations here, and they are not always solved by replacing the equipment.
Older furnaces and air conditioners eventually reach a point where the manufacturer no longer supports them with replacement parts. A repair that would have been straightforward on a newer unit becomes a parts hunt, and even when the part turns up, the repair cost has to be weighed against what the equipment has left in it. We look at the full picture before recommending anything, including whether a repair on aging equipment makes financial sense or whether replacement is the cleaner answer.
Duct systems in older homes were often sized for the original layout and the original equipment. When either of those changes, the duct system may not keep up. A room that is always too cold in winter or too warm in summer, a system that runs longer than it should to hit the setpoint, or a house that feels uneven from one end to the other: all of these can trace back to ductwork that was never properly balanced. We repair and seal duct runs, and where the layout itself is the problem, we talk through what it would take to address it before any work is scheduled.
The honest answer is that the price follows the diagnosis. A refrigerant leak at the evaporator coil and a failed capacitor on the condenser are both "AC not cooling" calls, and they cost different amounts to fix. What drives the number is what the fault turns out to be, what has to be reached to get to it, and whether a repair is the right call or a replacement is.
When you call, we go through the symptoms with you and give you a sense of what the diagnostic visit covers and what it costs. The repair or replacement scope is priced before any work starts, so you know what you are agreeing to. If you have already received a quote from another contractor and want a second opinion, that is a reasonable call to make and we welcome it. The repair or install scope priced before the work starts is how every job goes here, whether it is a tune-up or a full system replacement.
There are no invented figures on this page. The price is confirmed on the call, and it reflects the actual job.
We take calls every day from 6:30 AM to 9:30 PM, and that covers both scheduled visits and urgent calls when the system is down. We do not promise a specific arrival window, but urgent calls are answered and prioritized within the service day. When you call, we scope the situation on the phone, confirm what the visit covers, and get the appointment on the schedule.
A no-heat call in the middle of a northern Illinois winter and a no-cool call during a July heat wave are the two situations that cannot sit. We take those calls as soon as the schedule allows. For rental properties and commercial spaces where a tenant or a business has to stay operational, we work around the occupancy as much as the job allows. The scope and the access plan are covered on the call so the visit can proceed without delay.
A tune-up is a good time to find out what a system needs, and scheduling one before the peak season is the way to avoid the urgent call altogether.
A furnace tune-up in the fall and an AC tune-up in the spring are the straightforward way to catch the faults that would otherwise surface at the worst possible time. The visit covers the mechanical components, the controls, the filter and airflow, and the measurements that tell you whether the system is operating the way it should. The findings are explained before you are asked to do anything about them.
Standing water near the air handler or furnace is usually a condensate issue: a clogged drain line, a cracked drain pan, or a float switch that has tripped the system off to prevent overflow. It can also point to a refrigerant problem that is causing the coil to freeze and then thaw. Either way, it is not something to run the system through. Call and describe what you are seeing and we will scope the diagnostic from there.
When the system is running but the air coming out of the registers is weak, the cause is usually a blower fault, a severely clogged filter, a duct leak, or a coil that is icing over. Each of those has a different fix, and the visit works through them in order. Duct sealing addresses the leak directly when that is what the inspection finds.
A furnace that starts and then shuts off, or one that attempts to ignite and fails entirely, is often dealing with a dirty or failing flame sensor, an igniter that is at end of life, or a pressure switch issue on the inducer circuit. These faults show up as fault codes on most modern furnaces, and the technician who comes out reads those codes as part of the diagnostic. The fix is confirmed before any part is replaced.
Banging on startup, squealing during operation, and rattling from the cabinet or ductwork all point to specific mechanical problems. None of them resolve on their own, and running a system through a noise that has changed recently puts additional stress on components that are already showing wear. Describe the sound when you call and we will scope it before scheduling.
A system that starts, runs briefly, and shuts off before the space reaches the set temperature is working harder than it should and wearing out faster than it would otherwise. Short cycling has several causes: an oversized system that satisfies the thermostat too quickly, a refrigerant issue, a dirty coil reducing heat transfer, or a fault in the controls. The diagnostic identifies which one before a repair is recommended.
When a furnace or AC reaches end of life, the instinct is often to replace it with the same size. That is not always the right call. Equipment that was oversized to begin with will short-cycle on a new unit the same way it did on the old one. A house that has been air-sealed, re-insulated, or extended since the original equipment was installed has different load requirements than it did then.
We size replacement equipment based on what the property actually needs, not on what the nameplate of the old unit says. That means looking at the square footage, the insulation and window situation, the duct system, and how the house performs in practice before specifying a replacement. An oversized furnace or AC is not a more comfortable system. It is a system that costs more to run and wears out faster. Getting the sizing right at installation is the part of a replacement job that the equipment price does not cover on its own.
For homes in the area that are weighing a heat pump against a straight furnace-and-AC replacement, that conversation is worth having on the call. Cold-climate heat pump models now carry performance ratings that change the calculus for northern Illinois winters, and the installation connects to existing ductwork in most cases.

If you are in the area and not sure whether you fall inside it, call (224) 539-2898 and we will tell you.
Yes. The old equipment is removed as part of the replacement job. If there is anything specific about the removal that applies to your property, go over it on the call when the work is scheduled.
It depends on what the system is doing and what the diagnostic finds. A system that is losing efficiency but still running reliably may have several good years left with proper maintenance, while one that requires repeated repairs or can no longer hold temperature on the coldest or hottest days is closer to the end of that calculation. We look at the equipment before recommending anything, and we explain the repair-versus-replacement math in plain terms so you can decide.
We clear the work area before leaving. Any panels that were removed are replaced, and the space around the equipment is left the way it was found. If there is anything about the area that could not be fully restored, we let you know before we leave.
Check the thermostat settings first, including that it is set to the right mode and the temperature is above or below the current room temperature as appropriate. Check the filter, since a clogged filter can shut the system down. Check the breaker for the air handler and the outdoor unit. If none of those restore operation, call and describe what the system is doing and we will scope the visit from there.
