We install new systems, replace failed or undersized equipment, and size outdoor units to support additional zones down the road. Every project starts with the load calculation, not a catalog recommendation.
One outdoor unit, one indoor air handler. The right fit for a room over the garage, a finished basement, or a three-season addition that the central system was never designed to reach.
One outdoor unit supports up to five indoor air handlers, each on its own thermostat. Upper and lower floors can run different temperatures without one affecting the other.
If existing equipment has failed or no longer fits the load of the space, we remove it, recalculate the BTU requirement, and install a replacement matched to how the room is used today.
We can size the outdoor unit during installation to accept additional indoor zones later. You avoid replacing the condenser if you decide to expand coverage to another room.
Every residential project includes startup testing on each zone and a walkthrough of the controls, thermostat settings, and filter schedule before we close the job.
A dedicated unit for one space. Server rooms, treatment rooms, and commercial suites that need climate control separate from the building's main system are the most common applications.
One outdoor unit serves multiple spaces with independent temperature control. Useful for offices, medical suites, and multi-tenant buildouts where different areas keep different hours.
The indoor unit mounts inside a ceiling cavity and connects to standard registers through short duct runs. No visible equipment in the finished space.
Distribute conditioned air in multiple directions from a single ceiling-mounted point. Standard choice for open office floors and retail interiors where wall space is limited.
Our EPA-certified team completes every commercial installation. All work follows manufacturer specifications and the local code requirements for your building type.
Five styles cover the ceiling heights, wall layouts, and room types we see most often across Mokena properties.
Mounts near the ceiling on an open wall. Works in bedrooms, home offices, and most living areas without structural changes.
Sits low on the wall, delivers air upward. Fits rooms with limited ceiling height, large window banks, or attic conversions where the upper wall cannot be used.
Recessed into the ceiling, distributes air in four directions from one unit. Practical for open floor plans and commercial spaces where wall hardware is not an option.
Mounts flat against the ceiling surface with no recess required. Used in commercial garages, drop-ceiling lower levels, and light-commercial buildings with shallow ceiling cavities.
Hidden inside a ceiling void with short duct runs to standard registers. Used when the owner wants zoned coverage with no visible indoor equipment.
A technician visits, evaluates the spaces you want covered, and identifies what the installation will require, including any electrical panel work, before equipment is ordered.
We calculate the BTU requirement for each room individually. Correct sizing prevents short-cycling, humidity problems, and early equipment failure.
You get a written cost before installation begins. We also confirm which systems qualify for the federal tax credit and Illinois rebate programs at the estimate stage.
Our EPA-certified technicians handle mounting, refrigerant line connections, electrical work, and the exterior wall penetration the line set requires. Same crew that did the estimate does the work.
We test every zone, confirm the system runs to spec, and walk you through the controls before we leave.
Every installation carries a workmanship warranty. Most equipment includes a manufacturer warranty. We go over the specific terms at the estimate.

Each indoor unit runs on its own thermostat. A home office holds one temperature while a bedroom holds another. In two-story homes where upper and lower floors sit several degrees apart, zone control is the most direct fix.
Mini-splits operate as heat pumps. Cold-climate models hold their output well below 0 degrees Fahrenheit, which covers what Will County winters actually produce, including polar vortex drops. One system handles both seasons.
Duct runs in older homes lose conditioned air into walls, attics, and crawl spaces before it reaches the room. A ductless unit delivers air at the point of use. You stop paying to condition spaces between the mechanical room and the register.


The line set runs through a single wall opening, roughly three inches wide. Most single-zone installs finish in one day. The house stays livable throughout.
Each unit filters the air it conditions. With no shared ductwork, dust and allergens do not get distributed room to room. Homeowners managing allergies notice the difference quickly.
Compatible models connect to an app for remote adjustments and scheduling. Some send maintenance reminders and diagnostic alerts.


ENERGY STAR-certified ductless systems may qualify for a federal tax credit of up to 30 percent of the installation cost. The credit comes off your tax liability dollar for dollar.
State rebates apply to qualifying equipment based on the efficiency rating of the unit installed. Not every model qualifies. We confirm eligible systems at the estimate before anything is ordered.
Qualifying installations can be financed with approved credit. Call (815) 806-1055 or contact us online to go over rebate eligibility and financing options at your estimate.
We have been in this market for over 50 years. We know the housing stock, the building types, and what the local winters require from heating equipment. That context shows up in how we size and spec systems.
Every installation is completed by our own EPA-certified technicians. No subcontractors. The technician who evaluates your space is part of the team that installs the system. Each tech passes a background check before entering your home.
We calculate the correct system size before recommending equipment. If a smaller unit covers your needs, we say so. If your layout requires a larger outdoor unit for future expansion, we explain why before anything gets ordered.
We handle questions and maintenance after installation. For after-hours service, call (815) 806-1055.
Yes. Cold-climate heat pump models are rated to produce heat at temperatures well below 0 degrees Fahrenheit. We select equipment rated for those conditions during your load calculation. If you want to review specific cold-climate models, bring it up at the estimate.
We calculate the BTU requirement for each room using square footage, ceiling height, insulation values, window exposure, and how the room is used. An oversized unit short-cycles and leaves humidity uncontrolled. An undersized one runs continuously and never reaches the set point. We do not size by square footage alone.
No. The indoor and outdoor units connect through a small exterior wall opening for the refrigerant line, wiring, and condensate drain. Finished basements, garage conversions, and room additions without ductwork are common applications.
Federal law limits refrigerant handling to EPA-certified technicians. The work also requires pressure testing and startup procedures that need specialized equipment. A self-install voids the manufacturer warranty. Call us to schedule a certified installation.
The upfront cost is higher than a window unit or portable air conditioner. The indoor air handler stays visible on the wall or ceiling. For rooms used year-round, the operating cost difference typically offsets the higher purchase price over time. Request an estimate to compare real numbers for your situation.
We confirm which systems qualify for the federal tax credit and the Illinois ENERGY STAR rebate at the estimate stage, before equipment is ordered. Rebate filing procedures vary by program. Ask at your estimate and we will walk you through what is required.
