What to Expect from the HVAC Installation Process

Why Proper Installation Matters

Your HVAC system is one of the largest investments in your home’s comfort and value. In a climate like St. Louis—where winters dip below freezing and summers bring heavy humidity—having a correctly installed system isn’t optional. It determines how efficiently your home stays warm in January and cool in July.

Improper installation is the leading cause of reduced HVAC performance. Even the best equipment can lose up to 30% efficiency if ductwork, sizing, or airflow aren’t optimized. That’s why Rick Rasch Heating & Cooling focuses on precision installation—every connection, seal, and calibration is done to manufacturer and local code standards.

When you know what to expect, the entire process feels seamless and stress-free.

Step 1: Consultation and Home Evaluation

The process starts with a comprehensive in-home assessment. A certified Rick Rasch technician inspects your existing equipment, ductwork, insulation, and ventilation to determine your home’s heating and cooling needs.

Key factors include:

• Square footage and layout
• Number and size of windows
• Insulation and air sealing quality
• Existing duct conditions
• Energy usage patterns
• Preferred comfort levels

The technician performs a Manual J load calculation, ensuring the system is properly sized—not too large (which causes short cycling) and not too small (which strains the equipment).

This stage also includes a review of your comfort goals—whether you want zoned control, improved air quality, quieter performance, or better humidity management.

 

Step 2: System Selection and Proposal

Based on the evaluation, Rick Rasch Heating & Cooling recommends equipment options tailored to your home and budget. The proposal outlines:

• Equipment type (gas furnace, heat pump, hybrid system, etc.)
• Efficiency ratings (AFUE and SEER2)
• Warranty details
• Installation timeline
• Estimated cost and potential rebates

Homeowners can also explore add-ons such as smart thermostats, whole-home humidifiers, or UV purification systems. Rick Rasch’s team provides transparent pricing with no hidden fees—so you know exactly what’s included before work begins.

 

Step 3: Scheduling and Preparation

Once you approve the proposal, the team schedules installation at your convenience—usually within a few days for standard systems.

Before installation day:

• Clear access around the furnace, air handler, and outdoor unit.
• Move fragile or valuable items away from the work area.
• Ensure pets are secured in another part of the home.

Rick Rasch’s technicians arrive on time, uniformed, and ready with all tools and protective coverings to safeguard your floors and furniture.

 

Step 4: System Removal and Site Preparation

Old equipment is safely disconnected and removed for proper disposal or recycling. If needed, the team cleans and preps the area for the new unit—leveling surfaces, adjusting duct connections, and ensuring adequate airflow.

This step may also include sealing duct leaks, installing vibration pads, or upgrading venting materials. Taking time for preparation ensures your new system operates quietly, efficiently, and safely.

 

Step 5: Equipment Installation

This is where precision craftsmanship makes all the difference. Rick Rasch Heating & Cooling follows a structured process that meets or exceeds all manufacturer specifications.

Indoor Equipment Installation

• Set furnace or air handler on vibration-reducing pads
• Connect ductwork and seal all joints for airtight efficiency
• Install condensate drain lines and safety overflow systems
• Wire electrical and control components

Outdoor Unit Installation

• Mount condenser on a stable pad
• Connect refrigerant lines and insulate them properly
• Check refrigerant levels for correct pressure and charge
• Verify clearance for ventilation and accessibility

If installing a new thermostat, the technician connects and calibrates it for precise temperature control. Smart thermostats are synced with Wi-Fi and configured for your household’s routine.

 

Step 6: Testing and Quality Control

After the physical installation is complete, technicians perform a full system startup and performance test. They verify:

• Correct refrigerant charge and airflow
• Proper ignition, heating, and cooling cycles
• Electrical safety and grounding
• Venting and carbon monoxide levels
• Thermostat communication and accuracy

Each reading is compared to manufacturer standards to ensure your system is performing at its rated efficiency.

 

Step 7: Customer Orientation

Before leaving, the team walks you through every detail of your new system. They explain:

• Thermostat programming
• Filter maintenance schedules
• Seasonal care and warning signs to watch for
• Warranty registration steps
• Maintenance plan options

This personal handoff ensures you feel confident operating your system from day one.

 

Step 8: Follow-Up and Maintenance

Rick Rasch Heating & Cooling doesn’t consider installation complete when the equipment is running—it’s complete when you’re satisfied. A follow-up check ensures your system performs correctly under regular use.

Homeowners are encouraged to join a seasonal maintenance program, which includes tune-ups, priority scheduling, and discounts on parts and labor. Regular service protects your investment and keeps the warranty valid.
