The Real Timeline To Replace an AC Unit
Is your air conditioner on its last legs? If you’re sitting in a warm house wondering how long you’ll have to suffer before a new AC comes to the rescue, you’re not alone. This is one of the most common questions we get at One Hour Heating and Air.
The quick answer? Most AC unit replacements take just one day. But there’s more to the story than just swapping one box for another. Let me walk you through the whole process.
What Makes Some AC Replacements Take Longer Than Others?
Not all AC unit replacements are created equal. Several factors can turn a simple job into something more time-consuming:
When you’re replacing a standard central air unit with a similar model, we can usually knock it out quickly. But if you’re upgrading from window units or need new ductwork installed, that’s a whole different ballgame.
Location matters too. Is your unit easily accessible in the backyard, or is it hiding in a cramped attic or crawl space? The harder it is to reach, the longer the job takes.
Sometimes we open things up and find surprises—corroded lines, damaged wiring, or leaky ducts that need attention. These discoveries add time but addressing them now prevents bigger headaches later.
And don’t forget about permits and inspections. Depending on where you live, your city might require official paperwork and inspections. We handle all that for you, but if your local office moves at a snail’s pace, it can stretch the timeline.
Our Step-by-Step Replacement Process
At One Hour Heating and Air, we’ve streamlined our process to get you cooling again as quickly as possible. Most installations take 4-8 hours from start to finish. Here’s how it all happens:
1. Initial Call and Home Evaluation (60-90 minutes)
Everything starts when you call us. We’ll schedule a time—often the same day—to visit your home and assess your current system. We’ll look at your home’s size, layout, your energy goals, and what issues you’re having with the current setup.
2. Quote and System Selection (Same day or within 24 hours)
We’ll discuss your options without the pushy sales pitch. Different models, efficiency ratings, warranties, pricing, and even available tax credits—we lay it all out honestly.
3. Scheduling the Replacement (1-2 days turnaround)
Once you give us the green light, we book your installation. In many cases, we can be there the very next day.
4. Removing the Old Unit (1-2 hours)
On installation day, we start by safely shutting down and disconnecting your old system. We’ll properly recover any refrigerant and remove the old equipment.
5. Installing the New AC Unit (3-5 hours)
Next comes the main event. We position your new unit, connect all the necessary lines (electrical, refrigerant, drainage), and make any needed ductwork modifications.
6. System Start-Up and Testing (1 hour)
With everything connected, we power up your new system and put it through its paces. We check airflow, cooling capacity, temperature differences, and make sure everything’s running like a dream.
7. Walkthrough and Cleanup (30-45 minutes)
Before we leave, we’ll show you how to use your new thermostat, explain maintenance like filter changes, and answer any questions. Then we clean up so thoroughly you might wonder if we were ever there.
When It’s Time to Call for a Replacement
Not sure if you need a new AC yet? Here are the signs it might be time to give us a call:
- Your system is getting up there in years—10 to 15 years is typically when an AC unit starts showing their age.
- If your AC breaks down every summer like clockwork, that’s not bad luck. It’s a sign the system is wearing out.
- Notice your energy bills climbing? Older units become less efficient over time. Today’s high-efficiency models can slash your cooling costs by 20% or more.
- When your AC unit struggles to cool your home even when it’s running constantly, no repair will magically restore its youth.
- Weird noises—rattling, hissing, grinding—aren’t just annoying. They’re your AC crying for help.
- And if you’re selling your home or renovating, a new AC unit adds serious value. Buyers love seeing a fresh system that won’t need replacement soon.
Quick Answers to Common Questions
Can you really replace an AC Unit in one day?
Yes! Most replacements wrap up in a single day unless there’s major ductwork or electrical work needed.
Do I need to leave during installation?
Not at all. You can stay home—we’ll just let you know when the power needs to be off briefly.
When’s the best time to replace an AC Unit?
Spring and fall are ideal before the summer rush hits, but honestly, we install systems year-round.
Should I replace my furnace at the same time?
Not always necessary, but matching systems often work better together. We’ll explain what makes sense for your situation.
How long will my new AC last?
With regular maintenance, expect 15-20 good years from your new system.
