AC Unit Installation: How Long Does it Take to Replace?

You’re in your thinnest shorts, with the ceiling fan going, a box fan, and a hand fan, and you’re still boiling hot— you need your AC fixed ASAP. 🥵 When you can’t take another minute of the summer’s heat with a broken AC, you want it repaired and fast. But how long does it take to replace an AC unit? You’ll love this answer— it depends.

Yes, unfortunately, when you have a professional HVAC team inspect your air conditioner only to determine that repairs won’t cut it and it needs to be replaced, the first thing you think is, “How long before I have a new system?” The timeline for a project like this can depend on many factors, including:

• Scope of the project
• Type of AC being installed
• Availability
• The location of your AC unit

All these things considered, for the most part, you can expect an AC replacement to take between 2 and 8 hours. Let’s dive into more details so you can plan ahead for when the unthinkable happens, and you’re left fanning yourself to cool off!

8 Signs You Need to Replace Your Air Conditioning System

First things first— how do you know it’s time to replace your AC unit vs. repair it? There are a few tell-tale signs that, yes, can indicate a repair is needed, but also symptoms of AC replacement.

Oftentimes the cost of repairs inch so close to the cost of replacement that it might be your best bet. If you notice any of these signs, it’s definitely time to get a professional inspection of your system to determine whether to repair or replace it.

1) Your Unit is Over 15-20 Years Old ⌛

Most AC units are only meant to last between 15 and 20 years, so if your unit is nearing or past its intended lifespan, a replacement is likely in order. Even if it’s still running, it’s likely not working as efficiently as it can, and its days are numbered.

2) The System Only Blows Warm Air 🫠

When your AC is only blowing warm air, it could mean a few things. It could be an issue with your compressor, or it could also indicate issues with the ducts themselves. Either way, a professional inspection is vital to determine the root cause.

3) Higher-Than-Normal Energy Bills 📈

If your energy bill is significantly higher than normal, that’s a sure sign that your AC unit isn’t running efficiently — and it might be time for an upgrade. This can happen because the unit is starting to work twice as hard to cool your home. It’s likely costing you more money to continue running the old system than it would cost to replace it.

4) Unit is Leaking Water or Freon 💦

If your AC unit is leaking water or Freon, it’s a sure sign that something isn’t right. Leaking can be caused by damaged components of the system, and repairs might not be a viable option.

5) You Experience Moisture and Humidity Issues 🌡️

If you experience moisture or humidity issues in your home, it could indicate that the system isn’t working as efficiently as it should. The same is true if your AC keeps cycling on and off frequently — a sign of an inefficient system.

6) Weird Noises Coming From the Unit 🔊

If your AC starts making strange noises, such as knocking, buzzing, or rattling, it could be a sign that something is wrong with the system. A professional can inspect and diagnose what’s causing the noise.

7) Air Blowing From the Vents is Weak or Low 🌬️

If the air blowing from your vents is weak or low, it could be an issue with the compressor, or with dirty air filters. But if all these things check out, it might be time to get a new system.

8) Odd Smells Coming From Vents or AC Unit 👃

If your AC is emitting strange smells, like a musty or burning smell, it could be a sign that something is wrong like dirty air filters or an electrical issue. Get an inspection ASAP to prevent further damage or risk of fire.

At the end of the day, if you suspect any of these signs might indicate you need a new AC unit, it’s best to get a professional opinion. They can let you know if repairs are needed or if it’s time for an upgrade. Knowing the signs of when to replace your system will help you plan ahead and stay cool all summer long!

How Long Does AC Installation Take?

Installing a new AC system can take anywhere from 2-8 hours, depending on the size of the unit and the complexity of the installation.

That said, it’s always best to be proactive and take care of your AC system before the heat hits. Regular maintenance, proactive inspections, and annual AC tune-ups can help prevent any major repairs or replacements down the line.

Factors That Affect How Long It’ll Take to Replace an Air Conditioner

Square Footage: The size of your home is an important factor when it comes to how long it’ll take to install a new AC unit. Larger homes will require larger units, which take longer to install.

Accessibility: If the area where you want the AC installed has limited accessibility, this can also increase installation time. For example, high-rise structures, fenced-in areas, second floors, etc., can all prove difficult to install vs. the standard back or side of the house, which is easily accessible.

Type of Unit: Depending on the type of unit you’re installing, it may take longer or shorter to install. A standard split AC system has two components—the condenser and the evaporator coil—that must be installed separately. On the other hand, a ductless mini-split only requires that one component be installed since the air handler is already built-in.

Location of the Unit: Where you install your AC unit can also affect the installation time. Some locations require more access than others, which could increase the amount of time it takes to make sure everything is working properly.

Size of the Unit: The size of the unit also plays an important role when it comes to installation times. Smaller units can be installed relatively quickly, but larger units require more work and may take longer to install.

Replacement vs. New Install: Finally, the installation time also depends on if you’re replacing an existing unit or installing a new one. Replacing an AC system is usually quicker since many of the components are already in place. Whereas installing a new system takes much longer since all of the components must be installed correctly.

Regardless of your situation, it’s important to get professional help when it comes to AC installation and replacement. A qualified technician will have the experience and knowledge needed to make sure your unit is properly and safely installed in a timely manner.
