What to Expect During a Full HVAC System Installation

The day has finally arrived. After months—maybe even years—of dealing with a sputtering furnace that barely warms your home or an air conditioner that seems to have given up on summer entirely, you’ve made the decision: it’s time for a full HVAC replacement.

Buying a new heating and cooling system is a major investment, one that directly impacts your home’s comfort, energy efficiency, and even your monthly utility bills. That’s why choosing the right team for the job is just as important as choosing the right system.

Our team at A-1 Mechanical believes in ensuring our customers have full transparency on one of the bigger purchases they will make for their Las Vegas, home. In this blog, we break down the installation process step by step so you can be fully prepared when the big day arrives.

What to Expect During a Full HVAC System Installation

A-1 Mechanical will ensure your HVAC installation goes smoothly from start to finish so you can enjoy a home that feels just right—no matter the season.

Step 1: The Pre-HVAC Installation Prep Work

Before our licensed HVAC installers get to work on your full HVAC installation, there’s a little groundwork to do before they can begin.

This typically includes:

1. Home Evaluation: Our team will assess your current HVAC system, ductwork, insulation, and home layout to determine the best unit for your needs.
2. Load Calculation: Many companies skip this crucial step and install systems too large for the size of the home. Performing a load calculation is a must for our team; it helps us correctly size your new HVAC system so it heats and cools your home efficiently.
3. Selecting Your New System: Whether you’re looking for a high-efficiency furnace and a central AC or a heat pump to manage both your heating and cooling needs, we’ll help you choose the best fit for your home and budget.
4. Review Full HVAC Installation Scope: We’ll go over the fine details—your new HVAC system, if ductwork modification is needed, and the next steps. We’ll also review the final cost and how to finance your new full HVAC system installation.
5. Scheduling the Installation: Once the details are set, we’ll schedule your full HVAC system installation for a convenient day.

Step 2: Out With the Old HVAC

On installation day, our crew will start by removing your old HVAC system.

This involves:

1. Turning Off Power (and Gas): Safety first! We’ll shut off electricity and gas before getting started.
2. Disconnecting the Old Unit: Whether it’s a furnace, air conditioner, or both, we carefully remove the old system and properly dispose of it for you.
3. Checking and Updating Ductwork: If needed, we’ll inspect and modify ductwork to ensure optimal airflow for your new system.

Step 3: Installing the New HVAC System

Now, the fun part—getting your shiny new HVAC system in place!

1. Positioning the New Unit: We’ll carefully install your system in the ideal location, whether an indoor furnace or an outdoor AC unit.
2. Connecting Refrigerant Lines and Drainage: For air conditioners and heat pumps, we’ll hook up refrigerant lines and make sure drainage lines are clear.
3. Installing a New Thermostat: If you’re upgrading to a smart thermostat (a great choice!), we’ll install and program it for you. If you’re sticking with your existing thermostat, we’ll calibrate it to your new HVAC system.
4. Electrical and Gas Connections: We’ll connect everything safely and securely to ensure your system is ready to roll.

Step 4: Testing and Fine-Tuning Your New HVAC

Before we pack up, we make sure everything is running smoothly.

We will perform:

1. System Testing: We’ll run the system in heating and cooling modes to ensure it works properly.
2. Airflow Balancing: We will adjust dampers and registers to ensure even heating and cooling throughout your home.
3. Safety Checks: We’ll check for gas leaks, electrical connections, and refrigerant levels to ensure everything meets safety standards.

Step 5: Clean-up and Final HVAC Walkthrough

No one likes a mess, and A-1 Mechanical would never leave one behind or leave without saying goodbye.

Before we leave, we’ll:

1. Clean Up Any Debris: We make sure your home looks just as tidy as when we arrived.
2. Walk You Through the System: We’ll explain how to use your new HVAC system and thermostat, get you started with a fresh new filter, and set up maintenance reminders.
3. Answer Any Questions: Have a question? Ask away! We’re here to help.
