How Professional AC Installation Works: Complete Process
8 Steps of Professional AC Installation
Our NATE-certified technicians follow this comprehensive 8-step installation process to ensure your new AC system operates at peak efficiency from day one.
Initial Consultation and Load Calculation
We begin with a free in-home consultation where our experts perform a Manual J load calculation accounting for your home's size, insulation, windows, orientation, and Tucson's extreme climate. This ensures we recommend the correctly-sized system—not too large (which wastes energy and money) or too small (which can't keep up with demand). We discuss equipment options, efficiency ratings, costs, available rebates, and financing to help you make an informed decision.
Old System Removal and Disposal
On installation day, our crew safely removes your old AC system following EPA regulations for refrigerant recovery. We disconnect electrical connections, remove refrigerant lines, unbolt and haul away the outdoor condenser, remove the indoor air handler or evaporator coil, and properly dispose of all old equipment in an environmentally responsible manner. Your home is protected with floor coverings throughout this process.
Outdoor Unit Installation and Positioning
We install your new outdoor condenser on a level concrete pad or composite base, ensuring proper elevation for drainage and airflow. The unit is positioned for optimal efficiency, quiet operation, easy future service access, and aesthetic appeal. We verify the pad is perfectly level (critical for compressor longevity) and secured against Arizona's occasional high winds. Vibration-isolation pads minimize operational noise transfer to your home.
Indoor Air Handler or Evaporator Coil Installation
Inside your home, we install the new air handler (for heat pump systems) or evaporator coil (for AC-only systems) in your designated location—typically attic, garage, or closet. This includes secure mounting with proper clearances for service access, connection to existing or new ductwork using proper sealing techniques, installation of condensate drain lines with appropriate slope and termination, and verification of adequate ventilation around the unit. We ensure all connections meet manufacturer specifications and local building codes.
Refrigerant Line Installation and Electrical Connections
Our technicians run new copper refrigerant lines between outdoor and indoor units using proper brazing techniques (never compression fittings which can leak). Lines are insulated to prevent energy loss and condensation, properly sized for your system's capacity, pressure-tested for leaks before charging, and routed to minimize visual impact while maintaining efficiency. Electrical connections include appropriate wire gauge for system amperage, proper circuit breaker sizing and installation, disconnect switches for safety compliance, and thorough testing of all electrical components.
Thermostat Installation and Programming
We install your new thermostat (programmable or smart model based on your preference) in an optimal location away from direct sunlight, drafts, and heat sources. Installation includes proper wiring for your system type (conventional or heat pump), calibration to ensure accurate temperature readings, programming of schedules and preferences, and complete tutorial on operation and features. For smart thermostats, we configure Wi-Fi connectivity and app setup so you can control your system remotely.
System Charging, Testing, and Calibration
This critical step separates professional installation from amateur work. We precisely charge your system with the manufacturer-specified refrigerant amount using superheat and subcooling measurements (not just pressure gauges). We verify proper refrigerant charge across all operating conditions, test cooling capacity and temperature differential, measure airflow at supply registers, check electrical draw on all components, verify condensate drainage, test safety controls and limit switches, and calibrate thermostat for accurate operation. System must meet or exceed manufacturer performance specifications before we consider installation complete.
Final Walkthrough, Training, and Warranty Registration
Before leaving, we conduct a comprehensive walkthrough demonstrating all system operations and answering your questions. We explain thermostat settings and programming, show air filter location and replacement procedure, discuss maintenance schedule to keep warranties valid, provide written documentation of all work performed, register your equipment warranty with the manufacturer, and leave you with emergency contact information. We don't consider the job complete until you're 100% confident operating your new system and completely satisfied with the installation.
Signs You Need AC Installation Soon
Problem #1: System Age Over 12-15 Years
Problem #2: Rising Energy Bills Despite Normal Use
"Our 16-year-old AC was costing us over $500 monthly in summer. After getting quotes, we chose Intelligent Design for their expertise and transparency. They installed a Trane 17 SEER system in early April—perfect timing before the heat hit. First summer bill: $280. That's $220 monthly savings. The system already paid for itself in 2.5 years. Wish we'd done it sooner!"
Tucson Success Stories: Real Results from Real Homeowners
Energy Bill Savings: 47% Reduction in Cooling Costs
Oro ValleyChallenge
Homeowner's 14-year-old 14 SEER Goodman system was struggling to cool their 2,100 sq ft home during summer. Despite running constantly, indoor temperatures reached 82°F during peak afternoon heat. Monthly electric bills averaged $450 June through September. The old system was correctly sized at 3 tons but had lost 30% of its original efficiency due to age and wear.
Solution
We performed a comprehensive Manual J load calculation and recommended upgrading to a properly-sized Carrier Infinity 18 SEER variable-speed system. The installation included a new air handler, programmable smart thermostat, and complete refrigerant line replacement. Our team completed the installation in one day with minimal disruption.

Catalina FoothillsChallenge
Complete AC system failure occurred during a July heat wave with temperatures exceeding 112°F. The existing 19-year-old Trane system's compressor failed catastrophically, leaking refrigerant and oil. With elderly parents living in the home and temperatures inside reaching 95°F, this was a genuine emergency requiring immediate action.
Solution
We prioritized this emergency installation and had a new high-efficiency system delivered within 24 hours. Our installation crew worked extended hours to complete the full replacement in 36 hours from initial call. We provided temporary cooling solutions and communicated updates every 2 hours throughout the process.

Undersized System Replacement: Comfort & Efficiency Combined
MaranaChallenge
Growing family added 600 sq ft to their home five years ago but never upgraded their AC system. The existing 2.5-ton 15 SEER system was drastically undersized for the now 2,400 sq ft home. System ran 18+ hours daily during summer, struggled to maintain 78°F, and caused uneven temperatures between original home and addition. Annual cooling costs exceeded $4,200.
Solution
Our load calculation revealed the home required a 3.5-ton system—40% larger than existing capacity. We installed a properly-sized Lennox XC16 system with zoning capability to address the addition. Added features included UV air purification and a Lennox iComfort smart thermostat for zone control and scheduling optimization.

How to Prepare for Your AC Installation Day
Proper preparation ensures your AC installation goes smoothly and efficiently. Follow these steps to prepare your home and family for installation day.
Clear Access Paths and Work Areas
Remove furniture, decorations, and obstacles from around your existing AC system (both indoor and outdoor units). Clear a path from the front door to the indoor unit location. Move vehicles from the driveway to provide access for equipment delivery. This allows our installation crew to work efficiently and protects your belongings from accidental damage.
Secure Pets and Create Safe Spaces
Place pets in a secure room away from installation areas, or arrange for them to stay elsewhere during installation. Our technicians will be moving equipment and opening doors frequently, creating opportunities for pets to escape. A quiet, secure space also reduces stress for your pets during the noisy installation process.
Confirm Utility Access and Electrical Panel Location
Ensure our technicians can access your electrical panel (breaker box) and gas meter (if applicable). Remove any items stored in front of these utilities. Make note of which breakers control your current HVAC system. Our electrician will need clear access to install new circuits and disconnect old equipment safely.
Prepare Attic and Crawl Space Access
If your indoor unit is in the attic or crawl space, ensure our crew can access it easily. Move any stored items blocking the attic entrance. If your attic has a pull-down ladder, test it to ensure it's functioning properly. Clear insulation or debris from around the existing unit to provide a clean work area.
Prepare Outdoor Installation Area
Trim back any plants, bushes, or tree branches within 3 feet of the existing outdoor unit location. Ensure the area is accessible and level. If you have decorative rocks, pavers, or landscaping around the unit, consider temporarily removing them to facilitate equipment removal and installation. This prevents damage to your landscaping and speeds up installation.
Plan for Thermostat Location and WiFi Access
Decide where you want your new thermostat installed (we'll make recommendations during consultation). If upgrading to a smart thermostat, have your WiFi network name and password ready for setup. Consider thermostat placement in a central location away from direct sunlight, drafts, and heat sources for accurate temperature readings.
Plan Your Day and Arrange Time Off
Most installations take 6-10 hours. Plan to be home for the duration, though you don't need to supervise constantly. Schedule important calls or meetings for after installation. Arrange for someone to be home if you must leave. Have our technician's phone number handy for any questions. Plan meals that don't require extensive cooking, as power may be briefly interrupted.

Common Questions About AC Installation
Real answers to questions Tucson homeowners ask us every day
How much does it actually cost to install a brand new AC system in Tucson in 2025?
For most Tucson homes, a complete AC installation ranges from $5,000 to $6,500 for a standard 3-ton, 16 SEER system—which is what we install most often. Budget-friendly 14-15 SEER systems start around $3,500-$5,500, while high-efficiency 18+ SEER units with variable-speed technology run $6,500-$10,000 or more. The exact price depends on your home's size, the system's efficiency rating (SEER), brand choice (Carrier, Trane, Lennox, or Rheem), and whether ductwork modifications are needed. We always provide free in-home consultations with transparent, upfront pricing—no surprises. Plus, TEP and SRP often offer rebates up to $1,500 for high-efficiency systems, and we have flexible financing with 0% APR options available. Given Tucson's extreme heat where your AC runs 6-8 months straight, investing in a properly-sized, efficient system pays for itself within 5-7 years through lower energy bills. Call us at (520) 333-2665 for a free estimate with a detailed energy savings comparison tailored to your home.
Can you install my new AC system within a couple days if my current one completely died during summer?
Yes—we absolutely prioritize emergency AC replacements during Tucson's brutal summer months and can typically complete installations within 24-48 hours of your approval. We maintain a large inventory of high-quality Carrier, Trane, Lennox, and Rheem systems specifically so we can respond fast when families need cooling urgently. We have multiple installation crews and strong manufacturer relationships that allow us to get equipment quickly, even during peak season when temperatures hit 110°F+. Most residential installations are completed in just one day, including complete removal of your old system, professional installation, precise refrigerant charging, electrical work, thorough testing, and cleanup. Our NATE-certified installers work efficiently without ever compromising on quality—proper load calculations, code-compliant work, and manufacturer specifications are never skipped regardless of urgency. We've been serving Tucson families since 1979 with over 22,000 five-star reviews, so you can trust we'll get your home cool again fast while doing the job right. Call (520) 333-2665 now if you need emergency AC replacement.
What's the difference between a 16 SEER and an 18 SEER AC unit, and is the higher efficiency actually worth the extra money?
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently your AC converts electricity into cooling—higher numbers mean lower energy bills. In Tucson, where your AC runs heavily for 6-8 months every year, the difference is substantial. A 16 SEER system (mid-efficiency) typically costs $5,000-$7,000 installed, while 18 SEER models run $6,500-$9,000+. That extra $1,500-$2,000 upfront can save you $200-$400 annually on electricity compared to a 16 SEER unit. Over a 15-year lifespan, that's $3,000-$6,000 in total savings—often double your additional investment. Higher SEER systems also run quieter, maintain more consistent temperatures, and often include features like variable-speed compressors that provide superior humidity control and comfort. For Tucson's extreme climate, we generally recommend at least 16 SEER, but if your budget allows, 18+ SEER makes excellent financial sense and you may qualify for utility rebates up to $1,500. We'll calculate your exact savings potential during our free in-home consultation with a Manual J load calculation. Our NATE-certified technicians will help you choose the perfect balance of efficiency and affordability. Call (520) 333-2665 to schedule your free estimate.
Do I really need someone to do a Manual J load calculation, or can I just replace my old AC with the same size?
You absolutely need a proper Manual J load calculation—simply replacing with the same size is one of the biggest mistakes homeowners make and can cost you thousands in wasted energy and comfort problems. Here's why: your old system's size might have been wrong to begin with (many were oversized in the past), your home has likely changed (new windows, added insulation, room additions), and building science has evolved dramatically. An oversized AC cycles on and off constantly, never running long enough to properly dehumidify, wastes energy, and wears out faster. An undersized system runs constantly, struggles during Tucson's 110°F+ heat, and drives up electric bills. A Manual J calculation accounts for your home's exact square footage, ceiling height, insulation levels, window types and orientations, occupancy, Tucson's specific climate data, and more—ensuring your new system is perfectly sized for optimal efficiency and comfort. Our NATE-certified technicians perform this calculation on every installation at no extra charge. We've seen countless homes with 4-ton systems that actually need 3 tons, or vice versa. Proper sizing typically improves efficiency by 20-30% compared to guessing. This is included free with every estimate—call (520) 333-2665 to schedule.
Which AC brand is most reliable for Tucson's extreme heat—Carrier, Trane, Lennox, or something else?
All the major brands we install—Carrier, Trane, Lennox, and Rheem—are excellent choices for Tucson's demanding climate, and honestly, proper installation matters more than brand when it comes to longevity and performance. That said, here's what we see: Carrier and Trane are considered the industry's premium brands with exceptional build quality, robust warranties (10-year parts standard), and proven performance in extreme heat. They're typically priced $500-$1,000 higher than comparable models. Lennox offers outstanding efficiency options (up to 26 SEER) with excellent smart-home integration and competitive warranties. Rheem provides excellent value—reliable performance at lower price points, popular with budget-conscious homeowners. We also install Goodman for customers wanting maximum affordability without sacrificing quality. In Tucson's brutal climate where systems run nearly year-round, we've seen all these brands perform well when properly installed and maintained. The key factors are: correct sizing (Manual J calculation), expert installation by NATE-certified techs, precise refrigerant charging, and regular maintenance. A properly installed Rheem will outperform a poorly installed Carrier every time. We'll help you choose the best brand for your budget and needs during your free consultation. With 46+ years' experience and 22,000+ reviews, we install them all correctly. Call (520) 333-2665.
How long does the actual AC installation take from start to finish, and will I have to take off work?
Most residential AC installations in Tucson are completed in one full day—typically 6-8 hours from arrival to final testing and cleanup. You don't necessarily need to take time off work, though someone over 18 should be home to grant access and approve the work. Here's the typical timeline: We arrive in the morning (usually 7-9 AM to beat the heat), spend 1-2 hours removing your old system and preparing the installation site. The new outdoor condenser and indoor air handler installation takes 3-4 hours, including electrical connections, refrigerant line work, and any ductwork modifications needed. Final testing, calibration, system walkthrough, and complete cleanup take another 1-2 hours. We protect your floors and belongings throughout and leave your home cleaner than we found it. Larger homes, complex ductwork modifications, or electrical panel upgrades might extend installation to 1.5 days, but we'll tell you upfront during the estimate. Our crews work efficiently while maintaining meticulous attention to detail—our NATE-certified installers never rush critical steps like refrigerant charging or airflow balancing. We've completed over 22,000 installations with a 100% satisfaction guarantee. Call (520) 333-2665 to schedule your free consultation and we'll give you an exact timeline for your specific installation.
If I finance my new AC installation, what kind of monthly payments am I looking at for a decent system?
With our flexible financing options (subject to credit approval), you can typically finance a quality mid-range AC system for $100-$175 per month. Here's how the math works: A $5,500 system (our most common installation—3-ton, 16 SEER) financed over 60 months at standard rates comes to roughly $110-$130/month. We frequently offer promotional financing with 0% APR for qualified buyers, which brings that same system to just $92/month over 60 months with zero interest charges. For higher-efficiency systems ($7,000-$8,000), expect $140-$200/month depending on terms. Many Tucson homeowners find that their monthly payment is offset by immediate energy savings—a new high-efficiency system often cuts cooling costs $50-$150/month compared to an old, inefficient unit, especially during our brutal summer months. Plus, you eliminate repair costs that come with aging equipment. We work with multiple lenders to find the best rates and terms for your situation, and you can often get approved in minutes. The key is that you're not stuck suffering through another Tucson summer with a failing AC because you can't pay cash upfront. We'll show you all financing options during your free estimate with full transparency. Call (520) 333-2665 to discuss financing that fits your budget.
What happens to my old AC system—do you haul it away, or do I need to deal with disposal?
We handle complete removal and proper disposal of your old AC system—it's included in every installation at no additional charge, and you don't have to do anything. Our process follows all EPA regulations for safe refrigerant recovery (we're EPA Section 608 certified), which is legally required and environmentally critical. Here's what we do: First, we safely recover all refrigerant from your old system using certified equipment—refrigerants can't legally be vented to atmosphere and must be properly reclaimed or recycled. Then we disconnect and carefully remove both the outdoor condenser unit and indoor air handler or furnace coil, protecting your home from any damage during removal. We haul away all old equipment, including the condenser, air handler, old copper refrigerant lines (if being replaced), and outdated thermostats. If your old system contains valuable copper, we handle disposal responsibly and that value is already factored into our competitive installation pricing. Finally, we clean up completely—no old equipment sitting in your yard or debris left behind. You'll never need to make a landfill run or arrange special disposal. Our installation crews take pride in leaving your property clean and your new system running perfectly. This full-service approach is part of why we maintain 22,000+ five-star reviews and BBB A+ rating. Call (520) 333-2665 for a free estimate.
Should I get a heat pump instead of a regular AC, or does that not make sense in Tucson?
Heat pumps can make excellent sense for many Tucson homes, actually—they provide both cooling and heating in one efficient system, which is perfect for our climate with scorching summers and mild winters. Here's the key consideration: If you currently heat with electric resistance (like baseboard heaters or old electric furnace) or propane, a heat pump will save you substantial money on winter heating bills while providing the same quality cooling as a traditional AC. Heat pumps are 2-3 times more efficient than electric resistance heating. Modern cold-climate heat pumps work flawlessly even on Tucson's occasional 30-degree winter nights. If you heat with natural gas and have a newer furnace you're happy with, a traditional AC paired with your existing furnace might make more sense—gas heating is already efficient and affordable. However, dual-fuel systems (heat pump + gas furnace backup) offer the best of both worlds. Cost-wise, heat pumps run $6,000-$9,000 installed—similar to comparable AC-only systems. You may qualify for additional utility rebates and tax credits for heat pump installations. Our NATE-certified technicians will analyze your current heating system, energy costs, and usage patterns during your free consultation to determine which option saves you the most money long-term. With 46+ years serving Tucson, we install both systems expertly. Call (520) 333-2665 for personalized recommendations.
What warranty coverage do I actually get when you install a new AC system, and what does it really cover if something goes wrong?
You get comprehensive protection through three layers of warranty coverage designed to give you complete peace of mind. First, manufacturer equipment warranties: All major brands we install (Carrier, Trane, Lennox, Rheem, Goodman) include 10-year parts warranties when properly registered—this covers compressor, coils, and all major components if they fail due to manufacturing defects. Some brands offer extended warranty options up to lifetime compressor coverage. Second, our installation workmanship guarantee: We warranty all our labor, installation techniques, electrical work, refrigerant charging, ductwork connections, and system commissioning. If any installation-related issue occurs, we fix it at zero cost to you—this covers things like refrigerant leaks from our connections, electrical issues from our wiring, or airflow problems from our ductwork. Third, our 100% satisfaction guarantee: If you're not completely happy with any aspect of your installation, we work with you until it's right—no questions asked. This triple protection is backed by our BBB A+ rating with zero unresolved complaints and 22,000+ five-star reviews earned since 1979. Important note: Manufacturer warranties require regular professional maintenance to stay valid, which is why we offer optional preventive maintenance plans. These warranties mean you're protected whether it's an equipment manufacturing defect or installation error. Call (520) 333-2665 for complete warranty details with your free estimate.
