Licensed & Insured

10 Year Part Warranty
Dedicated to 100% Satisfaction
When your AC starts struggling through a Fredericksburg summer, you already know something is wrong. The house never quite cools down, the system runs constantly, and every month the energy bill climbs a little higher. At some point, repair stops making sense and replacement becomes the smarter call.
For 68 years, Garnett Heating & Air has been helping Fredericksburg homeowners make that transition without the stress. We specialize in AC replacement and installation, bringing honest assessments, quality equipment, and workmanship you can count on, backed by nearly seven decades of experience right here in the community. As a family-owned company that is fully licensed and insured, we are here when you need us, whether that is a planned upgrade or an urgent replacement.
We know that committing to a new system is a big decision. That is why we walk you through every step, explain your options without pressure, and make sure you are confident before any work begins. From the first call to the final walkthrough, we keep it simple.

What AC Replacement Really Solves
Fredericksburg homes take a beating every summer. High humidity, extended heat, and older housing stock all put extra demand on HVAC systems that were not built to last forever. A new, correctly sized unit does not just cool your home better. It runs more efficiently, costs less to operate, and takes the guesswork out of whether your system is going to make it through the season.
Right-Sized for Your Home
An oversized or undersized unit creates problems from day one. We assess your home carefully before making any recommendation, so the system we install is matched to your actual space and cooling needs, not just whatever is in stock.
Honest, Pressure-Free Service
You will never feel pushed toward a decision you are not ready to make. Our team lays out what we find, explains your options clearly, and lets you lead. No upsells, no scare tactics, just straightforward guidance.
Fredericksburg Expertise
We have been working in Fredericksburg homes for nearly seven decades. We know the housing stock, the climate, and the specific demands that Central Virginia summers put on HVAC systems. That familiarity shows up in the quality of every installation.
Lower Energy Bills From the Start
Older systems lose efficiency over time. A new unit running at full capacity uses less energy to do more, which means you notice the difference on your utility bill almost immediately after installation.
A Replacement You Can Plan Around
Waiting for your system to fail entirely means dealing with the fallout at the worst possible time. Replacing on your schedule gives you control over the process, the timeline, and the cost, without the emergency markup.
Licensed, Insured, and Accountable
Every installation is carried out by licensed and insured technicians who stand behind their work. If something is not right, we make it right. That commitment has kept Fredericksburg homeowners coming back for generations.
What Sets Our AC Replacement Apart
Replacing an AC system is only as good as the team doing the work. We do not cut corners on assessment, equipment selection, or installation, because we know the difference between a unit that runs and a unit that performs.
A Careful Assessment Before Anything Else
Before we recommend a system, we take a close look at your home’s layout, ductwork, insulation, and existing equipment. Getting this step right is what separates a replacement that lasts from one that underdelivers.
Technicians Who Know This Work
Our licensed and insured technicians have handled replacements across every type of home in the Fredericksburg area. They work carefully, communicate clearly, and do not leave until the system is running the way it should.
Local Roots, Long-Term Relationships
We are not a national chain dispatching whoever is available. We are a local, family-owned company that has built its reputation in Fredericksburg one job at a time, and we intend to keep it that way.
Available When It Matters
We offer 24/7 emergency support because sometimes a failing system cannot wait. If your AC gives out before your scheduled replacement, we are ready to respond.
When you work with Garnett, you are not just getting a new unit. You are getting a long-term partner who wants your home comfortable and your system running right for years to come.

Hear It From Your Neighbors
We’re proud of the work we do, but the real measure of our success is what our customers have to say.
What to Expect When You Replace Your AC with Garnett
We believe the process should be as stress-free as the result. Here is how a replacement works from start to finish.
Step 1: Get in Touch
Call us or submit a request online. We will ask a few questions about your current system and schedule a time to come take a look.
Step 2: In-Home Evaluation
A licensed technician visits your home and assesses your current setup, including ductwork, electrical connections, and the factors that affect which system will perform best in your space.
Step 3: Clear Recommendation and Upfront Pricing
We explain what we found, what we recommend, and exactly what it will cost. No surprises, no fine print. You make the call when you are ready.
Step 4: Scheduling That Works for You
Once you decide to move forward, we get you on the schedule quickly. We understand that being without a functioning AC in a Fredericksburg summer is not a comfortable situation.
Step 5: Expert Installation
Our technicians remove the old equipment, install your new system, and test everything thoroughly before leaving. Your home is left clean and your system is ready to run.
Step 6: Final Walkthrough and Ongoing Support
We take the time to show you how your new system works and answer any questions before we go. And if anything comes up after installation, we are a call away, just as we have been for Fredericksburg homeowners for nearly 70 years.
