What to Expect: Your Furnace Replacement Process
We believe the best customer experience starts with knowing exactly what’s going to happen and when. Here’s a simple breakdown of how we handle every furnace replacement from start to finish.
Step 1: Initial Consultation & Home Assessment
When you call Garnett Heating & Air, we’ll schedule a time that works for you to visit your home. During this visit, one of our experienced technicians will:
- Inspect your current furnace and heating system
- Evaluate your home’s size, layout, and insulation
- Ask about any comfort issues you’ve been experiencing (cold spots, high bills, etc.)
- Answer all your questions about the replacement process
This consultation is completely free, with no pressure and no obligation. Our goal is to understand your needs so we can recommend the right solution.
Step 2: Clear Recommendations & Transparent Pricing
Once we’ve assessed your home, we’ll walk you through your options. We’ll explain:
- Which furnace models fit your home and budget
- The energy efficiency ratings and what they mean for your monthly bills
- Any rebates, financing options, or warranties available
- A detailed, upfront price for the installation, no hidden fees or surprise charges
You’ll have all the information you need to make a confident decision. And if you need time to think it over, that’s perfectly fine. We’re here when you’re ready.
Step 3: Scheduling Your Installation
Once you’ve chosen your new furnace, we’ll work with your schedule to find an installation date that’s convenient for you. In many cases, we can complete the installation within just a few days or even the same day for emergency situations.
Before we arrive, we’ll confirm the appointment and let you know what to expect in terms of timing and any preparations you might need to make (like clearing a path to the furnace area).
Step 4: Professional Installation Day
On installation day, our licensed technicians will arrive on time, ready to work. Here’s what happens:
- We’ll protect your home with shoe covers and drop cloths
- Remove your old furnace safely and responsibly
- Install your new system with precision and care, following all manufacturer specifications and local codes
- Test the system thoroughly to ensure it’s heating properly and efficiently
- Clean up completely. You won’t even know we were there (except for the warmth!)
Most furnace replacements are completed in one day, typically within 4 to 8 hours depending on the complexity of the job. We’ll keep you updated throughout the process so you’re never left wondering what’s happening.
Step 5: Walkthrough & System Orientation
Before we leave, we’ll give you a full walkthrough of your new furnace. We’ll show you:
- How to operate your new thermostat
- What to listen for (and what’s normal) as your system runs
- How to change the air filter and how often to do it
- Maintenance tips to keep your furnace running smoothly for years
We’ll also answer any final questions and make sure you feel completely comfortable with your new system.
Step 6: Ongoing Support & Maintenance
Our relationship doesn’t end when the installation is done. We’re here for you long after your furnace is up and running.
- Warranty Protection: Your new furnace comes with manufacturer warranties on parts and labor. We’ll explain what’s covered and keep all your warranty information on file.
- Annual Maintenance: We recommend scheduling a yearly tune-up to keep your system running efficiently and catch any small issues before they become big problems.
24/7 Emergency Service: If something ever goes wrong, we’re just a phone call away, day or night.
Now that you know exactly what to expect, there’s nothing standing between you and a warm, comfortable home. Call Garnett Heating & Air today to schedule your free consultation, and let’s get your furnace replacement process started.
