WHY CHOOSE US
Your Package Unit Installation Contractor in Worth
-
Armstrong Air Dealer with Family Expertise
As a primary Armstrong Air dealer, we know their full lineup inside and out, with Ducane as a trusted alternative when it fits your situation better. Family ownership means we apply that knowledge with a homeowner's mindset: we choose equipment that balances durability with your actual budget, and we stand behind every decision.
-
Load Calculation Before Equipment Selection
Many contractors assume a replacement will be "the same size" as the old unit. We measure your home's insulation, window placement, ductwork condition, and usage patterns to size the unit correctly. An undersized unit runs constantly and costs more to operate; an oversized unit cycles inefficiently and costs more upfront. We get it right, and we show you the numbers behind our recommendation.
-

As a locally-owned company proudly offering Veteran & First Responder discounts, we understand the value of serving our neighbors well. We've kept Worth and neighboring communities comfortable since 2018, and we're here long-term to support what we install.

START THE CONVERSATION
Tell Us About Your Installation Project
Whether you're facing a failed unit, planning a springtime replacement, or exploring newer efficiency options, the first step is a candid conversation about your home, your comfort priorities, and your timeline. We'll discuss the brands and equipment tiers that fit your situation, walk you through financing options if needed, and build a transparent estimate before any work begins. Tell us about your current system's age, any comfort complaints you've noticed, and whether you're working within a specific timeline so we can plan accordingly.
OUR INSTALLATION PROCESS
Step-by-Step Package Unit Installation Process
We start with a thorough walkthrough of your home. Our technician measures square footage, inspects insulation quality, checks window orientation and condition, reviews your current ductwork, and asks about your typical heating and cooling patterns. This data feeds into a load calculation — a professional sizing analysis that determines the right capacity for your home. An accurate load calculation is the foundation of an efficient, properly operating system.
- Measure thermal load based on insulation, windows, and layout
- Evaluate existing ductwork for leaks or blockages
- Review your utility history and comfort concerns from the past year
- Run the calculation to determine correct unit size and efficiency tier
- Recommend equipment options from Armstrong Air and Ducane with clear performance/cost comparisons
Once we know your home's actual load, we'll present equipment options at different efficiency levels and price points. We explain the real-world difference between a standard-efficiency unit and a high-efficiency model — both in monthly operating cost and in total-cost-of-ownership over the system's lifespan. You'll see the financing options upfront so there are no surprises. We answer every question before you commit.
- Present 2–3 equipment tiers with clear performance and cost differences
- Explain SEER2 efficiency ratings and what they mean for your utility bills
- Walk through extended warranty options and what they cover
- Provide a fixed-price quote with all labor, materials, and permits included
- Discuss financing terms if you choose to spread payments over time
Once you've chosen your equipment and approved the quote, we'll schedule the installation at a time that works for your household. A few days before the technician arrives, we'll confirm the appointment, answer any final questions, and let you know what to expect during the work day. Most full package unit replacements take 4–6 hours.
- Confirm the installation date and technician arrival window
- Answer any last-minute questions about the process or the new unit
- Discuss site access, parking, and any special setup your home requires
- Verify that all equipment and permits are in place
- Prepare you for the sounds and activity during the removal and installation phases
On installation day, our technician begins with careful removal of the old unit — safely evacuating any remaining refrigerant, disconnecting electrical lines, and extracting the equipment without damaging your roof or surrounding areas. The new unit is positioned, bolted down, and integrated into your existing ductwork. All electrical connections are verified, refrigerant lines are flushed and charged to exact specifications, and every connection is pressure-tested for leaks.
- Safely extract the old package unit and disconnect all lines
- Clean and prepare the installation pad or rooftop area
- Position and secure the new unit with vibration-dampening mounts
- Connect ductwork, electrical, and refrigerant lines to factory specifications
- Verify airflow, check for refrigerant leaks, and confirm all connections are airtight
- Test all safety controls and operational modes before commissioning
After installation, we don't just power it on and leave. Our technician runs a full startup cycle — checking airflow at vents, verifying that both heating and cooling modes operate smoothly, confirming that the thermostat communicates correctly with the new unit, and testing all safety shutoffs. We walk you through the new system's controls, explain how to adjust settings, and hand you the manufacturer's manual plus our startup checklist. You leave with confidence and documentation.
- Run full heating and cooling cycles to verify all modes work correctly
- Check airflow distribution throughout your home
- Test thermostat integration and verify temperature control
- Walk through the new unit's controls and programmable options
- Provide the manufacturer's warranty and our installation documentation
- Explain recommended maintenance intervals and filter changes
- Answer any questions about operating your new system
PROTECT YOUR NEW SYSTEM
Pair Your Installation With a Maintenance Plan
A package unit is a long-term investment. Pairing your new installation with one of our maintenance plans ensures your system runs at peak efficiency and catches minor issues before they become expensive failures. Members enjoy priority scheduling for any repairs that do arise, and the routine tune-ups we provide help your new equipment stay comfortable and cost-effective for decades. Enrolling at the time of installation also means your first scheduled tune-up is already on the calendar, so nothing slips through the cracks during year one.
What's Included
- Scheduled seasonal system tune-ups.
- Priority scheduling for plan members.
- Multi-point inspection of your heating and cooling equipment.
- Peace of mind heading into Chicago's toughest weather seasons.
COMMON QUESTIONS
Frequently Asked Questions About Package Unit Installation
A package unit houses the entire heating and cooling system in one cabinet, usually mounted on your roof or outside wall. A split system splits the outdoor condenser and indoor handler into separate components. Package units are common in homes without a basement or utility closet, and they're often more efficient because both components sit outdoors. We work with both; the right choice depends on your home's layout and your long-term maintenance preferences.
A properly sized unit for a home your size runs efficiently without short-cycling or constant operation. Our load calculation measures your home's square footage, insulation quality, window exposure, and typical weather patterns — not assumptions. An undersized unit strains to reach your temperature setpoint on the hottest or coldest days; an oversized unit costs extra upfront and cycles on and off inefficiently. We get the sizing right so you're comfortable and efficient.
Most full replacements take 4–6 hours from equipment removal through startup testing. Complex ductwork modifications or roof work might extend the timeline. We'll give you an accurate time estimate during the pre-installation assessment so you can plan your day. Weather and unexpected ductwork issues can add time, and we communicate delays as soon as we know about them.
Modern thermostats are compatible with almost all new units, but not every old thermostat will communicate with new equipment. We verify thermostat compatibility during the assessment, and if you need a new one, we'll include it in the quote. A programmable or smart thermostat often pays for itself within the first few months through energy savings.
Armstrong Air and Ducane units include manufacturer warranty coverage that varies by equipment tier and typically protects major components for several years. We also offer extended warranty options that expand coverage and add labor protection beyond the standard terms. We'll detail all warranty terms clearly in your quote, and you'll have the full warranty documentation on file when the job is complete.
Not always. If your existing ductwork is well-sealed, properly sized, and in good condition, we can often reuse it with the new unit. However, if we find significant leaks, undersized ducts, or blockages, we'll recommend repair or replacement and explain how that affects airflow and efficiency. We'll walk through the options and costs during the assessment.
Yes. We partner with Wisetack so you can spread the cost over manageable monthly payments. We'll discuss financing options during your quote, and there's no obligation. Many homeowners find that financing a new, efficient system actually lowers their total monthly cost because the energy savings offset the payment.
We safely remove it and properly dispose of any refrigerant, copper, and other materials left behind. Refrigerant disposal follows EPA regulations to protect the environment, and recovered refrigerant is handled according to federal guidelines. Metal components are recycled wherever possible. You won't see or deal with the old unit at all — we handle the entire removal and disposal process from start to finish.
Typically no, unless we're routing new ductwork or need to access the thermostat or furnace connections inside your home. Most package unit installations happen entirely on the roof or outside the home, so your daily routine is rarely disrupted. We'll confirm any interior access needs during the pre-installation assessment so you know what to expect on installation day.
Your first routine maintenance should happen about 12 months after installation, then annually after that for most households. Some homeowners prefer twice-yearly tune-ups — once before cooling season and once before heating season — especially in our climate's wide temperature swings. A maintenance plan makes this scheduling automatic and helps reduce overall service costs compared to paying for one-off visits.
