We evaluate your space, optimal indoor unit placement for both function and aesthetics.
Good placement matters for performance and appearance. We assess refrigerant line routing, electrical requirements, and mounting locations that deliver the best airflow while looking professional.
Proper evacuation, charging, and line sealing ensure system reliability and efficiency.
Improper refrigerant work voids warranties and causes failures. Our EPA-certified technicians follow proper evacuation procedures, pressure-test all connections, and charge systems to manufacturer specifications.
We route lines discreetly, mount indoor units for best airflow and appearance.
Professional appearance matters. We hide electrical connections, insulate and protect refrigerant lines, and mount units where they perform best while looking clean and intentional.
We pressure-test lines, verify charge, confirm electrical connections, and test operation.
Every installation ends with complete system testing — pressure testing for leaks, electrical verification, refrigerant charge confirmation, and full heating and cooling operation before we finish.
Spread system costs with Wells Fargo financing options.
Don’t let upfront costs delay your comfort. We offer flexible financing through Wells Fargo with competitive rates and terms that fit your budget.
Tap a topic to see what matters for successful mini-split installation.
Indoor unit location affects both cooling performance and room appearance. We recommend mounting 7–8 feet high on a wall opposite the main seating area for optimal airflow distribution.
What we consider: airflow patterns, furniture placement, electrical access, refrigerant line routing, and visual impact. Corner mounting looks clean but reduces effectiveness.
Key Factor
Airflow & Aesthetics
Good placement delivers comfort while looking intentional, not like an afterthought.
Refrigerant lines connect indoor and outdoor units through a small hole in the wall. We route lines for the shortest practical run while protecting them from weather and damage.
Our approach: insulate all lines, protect from UV exposure, secure against wind movement, and hide connections where possible. Proper routing prevents leaks and maintains efficiency.
Key Factor
Protection & Insulation
Proper line protection prevents refrigerant leaks and maintains system efficiency.
Mini-splits require dedicated electrical circuits. We verify your panel capacity, install appropriate breakers, and run electrical connections to code.
Safety first: all electrical work follows NEC standards, connections are properly grounded, and we test voltage before startup. Improper electrical work is dangerous and voids warranties.
Key Factor
Code Compliance
Proper electrical work ensures safety and prevents equipment damage.
Undersized systems run constantly and never reach comfort. Oversized systems cycle frequently and don’t dehumidify properly. We calculate the right capacity for your space.
Our calculation: room square footage, ceiling height, insulation, window exposure, and heat sources. Single-zone or multi-zone depends on your layout and preferences.
Key Factor
Right-Sized Equipment
Proper sizing ensures comfort, efficiency, and equipment longevity.
Proper refrigerant work requires EPA certification and specialized equipment. We evacuate air from lines, pressure-test for leaks, and charge with the exact refrigerant amount.
Why it matters: air in the system causes compressor damage. Wrong refrigerant charge reduces efficiency and shortens equipment life. We follow manufacturer specifications exactly.
Key Factor
EPA Compliance
Proper refrigerant work is required by law and essential for system reliability.
Every installation ends with comprehensive testing — electrical verification, refrigerant pressures, heating and cooling operation, and remote control programming.
Our testing: compressor startup, fan operation, temperature differential, refrigerant pressures, electrical connections, and control response. We don’t leave until everything works correctly.
Key Factor
Complete Verification
Thorough testing ensures your system works properly from day one.
Professional installation from site assessment through final testing. Every Spencer mini-split installation follows the same eight-step process for reliable, efficient operation.
We evaluate the space, recommend indoor unit placement for optimal cooling/heating and aesthetics, assess outdoor unit location, measure square footage, and discuss budget and preferences.
We recommend single or multi-zone systems based on your needs. We explain efficiency ratings, noise levels, and pricing options. Financing is available.
Once approved, we schedule installation and confirm electrical capacity. We coordinate delivery and ensure all materials are ready before the installation date.
We mount the indoor unit(s), install outdoor condenser, run refrigerant lines, and route electrical connections. All connections are properly insulated and protected.
We evacuate air from the refrigerant lines per EPA requirements, pressure-test for leaks, and charge with the correct refrigerant amount to manufacturer specifications.
We complete all electrical connections, verify proper voltage, test compressor startup, and confirm system operation in both heating and cooling modes.
We train you on remote control operation, maintenance requirements, and provide warranty documentation. You’ll understand how to operate your new system efficiently.
Complete system verification — pressures, temperatures, airflow, electrical connections, and control response. We don’t leave until everything works correctly.
Our maintenance members enjoy priority scheduling, consistent system performance, and the confidence that comes from knowing a trained professional is keeping an eye on their equipment throughout the year.

Why Consider Financing?
Hover over the section to see the full list. Mini-split systems solve comfort problems where traditional ductwork isn’t practical or cost-effective.
From room additions to whole-house zoning, our technicians assess your specific situation and recommend the right system configuration. Single-zone or multi-zone, we handle complete installation with professional results.
Perfect for: new rooms where extending ductwork is expensive or impractical. Mini-splits provide immediate comfort without major renovation or ductwork modification.
Perfect for: finished basements, attic offices, or converted spaces. Mini-splits handle temperature extremes and humidity better than trying to extend central systems.
Perfect for: bedrooms that are too hot or cold compared to the rest of the house. Individual control lets you sleep comfortably without affecting other rooms.
Perfect for: homes where different areas need different temperatures. Multi-zone systems let each room have individual control and scheduling.
Perfect for: workshops, art studios, or garage conversions. Mini-splits provide year-round comfort in spaces that were never designed for conditioning.
Perfect for: older homes with radiator heat or no central air. Mini-splits add cooling and supplemental heating without major construction.
Typically 4–8 hours for a single-zone system. Multi-zone systems may take longer. We’ll estimate during consultation based on your specific installation requirements.
Single-zone systems range from mid-range to higher-end depending on efficiency. Multi-zone systems scale with zone count. Schedule a free estimate for specific pricing based on your needs.
No. Installation requires EPA refrigerant certification, electrical knowledge, and proper evacuation/charging procedures. Professional installation is mandatory for warranty coverage and safe operation.
We recommend mounting for optimal airflow and aesthetics — usually on a wall opposite the main seating area, 7–8 feet high. Corner mounting is less effective. We’ll advise the best location during assessment.
Lines run through a small hole in the wall or along the exterior. We insulate and protect them for durability and appearance. Routing is planned to minimize visual impact while ensuring proper function.
Yes, the outdoor unit (condenser) needs space. It’s about the size of a traditional AC condenser and can be mounted on the ground or a bracket. We assess placement during consultation.
Yes. Multi-zone systems can be expanded with additional indoor units connected to the same outdoor compressor, up to system limits. We plan for future expansion when possible.
Installation costs depend on system size, unit count, and line routing complexity. Get a free quote by contacting us for a site assessment.
Yes. Wells Fargo offers flexible financing with competitive rates. See options and apply online.
Most equipment includes 10-year compressor and 5-year parts warranties from the manufacturer. We include 1-year labor warranty on our installation work.
