Why Greater Houston Homeowners Trust Us for Mini-Split Installation
Factory-Certified Installation & Training
Our installation team is factory-trained and certified, meeting the highest standards for split-system installation, refrigerant handling, electrical integration, and warranty requirements. Every installer is factory-trained on the equipment we install, so your system is installed correctly and backed by full manufacturer support. This matters because proper installation determines your system’s efficiency, reliability, and warranty validity.
Zone-Based Design That Matches Your Home’s Layout
Unlike central AC that treats your entire home as one temperature zone, mini-split installation is about designing flexibility. We evaluate which rooms you want to condition, how you use them seasonally, and your aesthetic preferences. Then we design a system with wall-mounted indoor units positioned to deliver comfort without ductwork. Each room has its own thermostat, so you cool the bedroom to 68°F while keeping the living room at 72°F—no more fighting over temperature or wasting energy cooling empty rooms.
No Ductwork Means Cleaner, Faster Installation
Mini-split installation doesn’t require cutting walls to run ductwork or making your home a construction zone. We mount sleek wall units in conditioned rooms, run small-diameter refrigerant lines and electrical wiring along exterior walls or through minimal wall penetrations, and place the outdoor compressor in an inconspicuous location. Most installations take 1–2 days. Your home stays clean, your daily routine minimally disrupted, and you get a modern, efficient system without the mess of traditional HVAC work.
Proper Electrical Work and Code Compliance
Installing a mini-split involves electrical work—connecting the outdoor compressor to your electrical panel, running proper gauge wire, installing disconnect switches for safety, and ensuring everything meets local codes. We handle all electrical work as licensed electricians, pull permits, and coordinate inspections so your installation is documented and compliant. Improper electrical work voids warranty and creates safety hazards—we do it right.
Complete Startup Testing and System Commissioning
Before we leave, we test your new mini-split under full operating conditions: thermostat calls, compressor cycles, indoor units deliver cooled or heated air, and we verify temperature setpoint accuracy in each room. We check refrigerant charge to exact specifications, test electrical continuity, verify control board programming, and confirm that your wireless remote controls work properly. You won’t discover problems weeks later—we catch and fix everything during installation.

What Houston-Area Homeowners Say
Our Mini-Split Installation Process
From the first home assessment to the final walkthrough, every step is documented and done to code — so your new system performs from day one.
We begin by understanding your home and your comfort goals. We visit to evaluate which rooms you want to condition (bedrooms, home offices, additions, sunrooms), how you use them throughout the day, your preferred temperatures, and any aesthetic concerns about wall-mounted indoor units.
We assess your home’s structural layout: exterior vs. interior walls (mini-splits typically mount on walls with outdoor access), window orientations and solar exposure, insulation levels, and existing electrical service. We review your current HVAC system (if you have central AC) to understand whether this mini-split is supplementing existing cooling or replacing it entirely.
Based on this assessment, we recommend:
- Number of Indoor Units — A single-room installation (one indoor unit) or multi-room system (3–4 units on one outdoor compressor)
- Unit Placement — Which wall in each room provides the best air distribution and least obstructive mounting
- Outdoor Compressor Location — A spot that’s accessible for service, has adequate clearance for airflow, and is visually unobtrusive
- Refrigerant Line Routing — Whether lines run along exterior walls or require small wall penetrations to keep your home’s interior clean
Unlike central AC where “tonnage” is sizing, mini-splits are sized by BTU capacity (British Thermal Units per hour). We calculate the cooling and heating load for each room you’re conditioning, accounting for room size, window area, insulation, and Houston’s climate.
We present equipment options with different efficiency ratings:
- Basic Models — Entry-level efficiency with standard wireless remote control
- Mid-Range Models — Better efficiency (higher SEER ratings) with more features like sleep mode and quiet operation
- Premium Models — Maximum efficiency with smart home integration (app control, learning thermostats, voice control compatibility)
We explain the long-term costs and benefits: a higher-efficiency mini-split costs more upfront but delivers significant energy savings over 12–15 years. We calculate payback periods based on Houston’s typical cooling loads so you understand the financial impact.
We discuss whether you want cooling-only systems (summer conditioning, existing heating elsewhere) or heat pump systems (year-round comfort). Heat pump mini-splits cost more but provide efficient winter heating—ideal for homes without furnaces.
Mini-split installation requires proper electrical integration. We assess your electrical panel to determine available capacity, review breaker sizing, and plan the disconnect switch installation (required by code for compressor safety).
We calculate the electrical load the new system will draw—modern mini-splits are surprisingly efficient and often use less power than older central AC units. If your current panel has capacity, we integrate the mini-split into existing service. If upgrades are needed, we coordinate with licensed electricians or recommend panel upgrades.
We also discuss control options: standard wall-mounted thermostats, smart thermostats (programmable and app-controlled), or wireless remotes with advanced features. Smart controls let you adjust your mini-split from anywhere and create schedules that match your home’s occupancy.
Once you approve equipment selection, thermostat type, and financing, we order your system components (indoor units, outdoor compressor, refrigerant lines, electrical supplies). We coordinate the installation timeline with you—typically scheduling 1–2 days at your convenience.
We prepare site diagrams showing exactly where indoor and outdoor units will be positioned, refrigerant line routing, and electrical connections. You see the plan before installation begins.
On installation day, we begin by installing indoor wall-mounted units in each room you’re conditioning. We locate studs, secure mounting brackets, and ensure units are level and aesthetically aligned. We run refrigerant line connections and electrical wiring through carefully planned wall penetrations (typically ½-inch holes).
We place the outdoor condenser unit on a concrete pad with proper clearance for airflow and vibration isolation to minimize noise. We connect refrigerant lines from indoor units to the outdoor compressor, ensuring tight connections that prevent leaks.
All electrical work follows code: we run properly-sized wire from your electrical panel, install a disconnect switch between the panel and outdoor compressor (required for safe service disconnection), and ensure all connections are secure and grounded.
With the system physically installed, we charge refrigerant to exact manufacturer specifications. Incorrect refrigerant charge (too much or too little) is a common installation failure that reduces efficiency or prevents cooling. We use superheat and subcooling measurement methods to ensure charge precision.
We run the system through complete testing:
- Cooling Cycle Test — Thermostat calls for cooling, compressor starts, indoor units blow cool air, and we verify temperature reaches setpoint in each room
- Heating Cycle Test (if heat pump system) — Thermostat calls for heating, system reverses refrigerant cycle, and we verify warm air delivery
- Electrical Verification — All connections are tight, voltage is correct, and safety disconnect operates properly
- Control System Testing — Wireless remotes operate, temperature sensors read accurately, and all features work as designed
We verify that airflow is balanced in each room—some mini-splits have adjustable louvers or blade angles, allowing us to direct air for comfort and aesthetics.
Before we leave, we explain how your new mini-split operates: how to use the thermostat or remote control, seasonal expectations (cooling in summer, heating in winter), optimal temperature settings for efficiency, and how to maintain your system (filter cleaning, when to schedule annual service).
We provide all documentation: equipment spec sheets, installation records, warranty information, control system instructions, and our contact information for future service. We discuss maintenance plan options to keep your system running efficiently and prevent future failures.
For your new system, we register your warranty so you have direct manufacturer support access and extended coverage options.

Mini-Split Installation Questions Houston Homeowners Ask
A typical single-room installation takes 1 day. Multi-room systems (3–4 units) usually take 1–2 days, depending on the complexity of refrigerant line routing and electrical work. We coordinate the timeline with you in advance and minimize disruption to your home.
Usually, we route refrigerant lines along exterior walls or under trim to avoid wall cutting. If cutting is necessary, we make small penetrations (typically ½ inch diameter) through exterior walls, seal them properly, and keep interior walls clean and intact. Most customers are pleased with how minimally invasive the installation is.
Absolutely. A mini-split operates independently with its own outdoor compressor, so it doesn’t interfere with central AC. Many homeowners add mini-splits to supplement central AC in specific rooms that aren’t adequately cooled or to get zone control in key areas. The two systems run independently without conflict.
A cooling-only mini-split cools in summer but has no heating function. A heat pump mini-split reverses its refrigerant cycle to provide both cooling and heating from the same unit—ideal if you want year-round comfort without a separate furnace. Heat pump models cost more but offer complete climate control.
Yes, annual maintenance extends system life and maintains efficiency. We recommend a yearly tune-up before cooling season begins, including refrigerant pressure checks, coil cleaning, filter replacement, and electrical connector inspection. Houston’s humidity makes regular service especially important to prevent corrosion.
Many mini-split systems allow adding indoor units to an existing outdoor compressor, up to the compressor’s capacity limits. When you install the initial system, we consider future expansion and can design the outdoor unit with capacity headroom. Adding rooms later is typically simpler and cheaper than expanding central ductwork.
Yes. Manufacturer warranties cover equipment defects for 5–10 years depending on the component, and our installation work is covered by LMH Services’ 1-year labor warranty. For protection beyond the first year, we offer extended parts-and-labor plans through JB Warranties — no deductible, all brands, and transferable to a new owner at no charge. We provide all documentation so you understand warranty coverage and registration.
We strongly recommend professional installation. Mini-split installation involves refrigerant handling (EPA 608 certification required), electrical work (code compliance and safety), and precise commissioning. Improper installation voids warranty, creates efficiency losses, and may create safety hazards. Our factory training and certifications ensure your system works perfectly.
Installation costs depend on the number of rooms, equipment efficiency, electrical requirements, and refrigerant line complexity. Single-room systems are typically less expensive than multi-room systems. We provide a detailed quote after your home assessment so you understand costs before proceeding. Financing is available to make the investment affordable.
We verify cooling performance before finishing the installation. If the system isn’t performing to spec, we diagnose and fix the problem immediately—whether it’s a charge issue, connection problem, or equipment defect. Our work is warranted, so you can trust that everything is tested and ready.
