Furnace Direct Ships the Right Equipment to Your Door
We help you select the right system for your home, order it directly from the manufacturer, and have it delivered straight to your driveway. No middleman markup. No dealer overhead. Just the same equipment the big HVAC companies install — at a fraction of the price.
You get brand-new, factory-warranted equipment from names like Goodman, Daikin, Bosch, Whirlpool, and Day & Night. We handle the sizing, the ordering, and the logistics. All you need is someone to put it in.
Two Ways to Save
Whether you hire an independent installer or do it yourself, buying the equipment direct puts thousands of dollars back in your pocket.
Option 1: Hire an Independent Installer
There are plenty of HVAC companies that don't want to deal with picking up equipment, delivering it, and handling warranty logistics. They'd rather simply install it. These companies are more than happy to come out and give you a price on installing the equipment you've already purchased.
Because they're only quoting the labor — no equipment markup, no delivery costs, no warehouse overhead — you save a minimum of $2,000 compared to buying the full package from a traditional HVAC dealer.
We can help connect you with qualified installers in your area who work with homeowner-supplied equipment every day.
💲 Save $2,000+ on Equipment CostsOption 2: Install It Yourself
Some people even install this equipment themselves. If you're willing to spend a couple hundred dollars at Harbor Freight, you can buy a vacuum pump and a reclaim machine and swap out your AC system yourself.
It typically takes the average homeowner about two days to install their own AC system. There are plenty of YouTube videos that walk you through every step, and active online forums where experienced DIYers answer questions in real time.
That saves you even more money — the full cost of professional installation on top of the equipment savings you already got by buying direct.

The DIY Route: What You Need
Installing your own central air system isn't as intimidating as it sounds. With a couple hundred dollars in tools from Harbor Freight and a free weekend, you can get it done.
The key tools are a vacuum pump (to evacuate the refrigerant lines) and a reclaim machine (to safely recover the old refrigerant). Beyond that, it's mostly standard hand tools, a torque wrench, and some patience.
Most homeowners who go this route say the job takes about two days — one day to remove the old system and prep, one day to install the new one and get it running.
Basic Tools for a DIY Install
A trip to Harbor Freight and you're set. Most of these tools are useful for other projects around the house, too.
🔧
Vacuum Pump
Evacuates air and moisture from the refrigerant lines before charging the system.
♻️
Reclaim Machine
Safely recovers the old refrigerant from your existing system before removal.
🔨
Manifold Gauge Set
Monitors refrigerant pressure during evacuation and charging.
🧱
Torque Wrench
Ensures refrigerant fittings are tightened to spec — prevents leaks.
🔌
Multimeter
Tests electrical connections and verifies proper voltage to the system.
🪓
Standard Hand Tools
Wrenches, screwdrivers, drill, level, tin snips — the basics you probably already own.
⚖️ What Florida Law Says
Under Florida's Owner-Builder Exemption, homeowners have the legal right to perform construction work on their own personal residence — including HVAC installation. You are not required to hold a contractor's license to work on your own home.
However, you do need to follow the process. That means pulling a mechanical permit through your local building department, making sure the installation meets Florida Building Code, and scheduling the required inspections when the work is complete.
It's straightforward. Thousands of Florida homeowners use the owner-builder exemption every year for everything from plumbing to electrical to HVAC.
