Air Conditioning Replacement Cost In August 2023?

This is the most common question these days. When the Air Conditioner stops working, it causes a lot of inconvenience for you. The sweltering heat is unbearable and you need to figure out how much a replacement AC unit is going to cost you.

You’re worried it’s going to be an unexpected expense that strains your budget. The good news is you can get your AC

unit replaced if it is not working properly and it is often necessary to keep your home comfortable during the hot summer months. The bad news is AC units can cost between $3000 to $10000 or more for a complete replacement of your home’s central air conditioning system.

How Much Does It Cost To Replace An AC Unit?

How Much Does It Cost To Replace An AC Unit?

The budget and cost of your AC unit depend on the size and efficiency of the unit you need. You can expect to pay between $3000 to $10000 for a new central AC unit.

For a small to mid-size home (around 1500 to 2500 square feet), an AC unit will cost about $3000 to $5000 on installation. High-efficiency units with a higher SEER rating, around 15 to 20, will be on the higher end of that range.

If you have a larger house, (3000 square feet or more), you’re probably looking at $6000 to $10000 or even more for a powerful, efficient unit. The exact cost will also depend on the brand and any advanced features like multi-zone control.

Installation fees average $300 to $1000 per unit, depending on the complexity of your setup. It’s best to get multiple estimates from licensed HVAC contractors in your area for the most accurate price.

While it’s not a small investment, a new efficient AC unit can significantly lower your utility bills over its lifetime. Newer units are also less prone to costly repairs. So, if your current air conditioner is more than 10 years old it is better to replace it.

The installation costs make up a good chunk of the total air conditioner replacement cost. For a typical three-ton unit, you’re looking at between $3000 to $4500 for installation alone. The exact price will depend on factors like your home’s size, the unit’s location, any ductwork required, and your area’s labor rates.

Installation Includes Things Like:

  • Removing your old AC unit and disposing of it properly
  • Installing the new unit
  • Connecting it to your home’s electrical system
  • Charging the unit with refrigerant
  • Ensuring proper airflow by connecting it to vents and ducts

For a larger 4 or 5-ton central AC, the installation costs will be on the higher end of the range, from $4,000 to $6,000. Split systems and window units are usually cheaper to install at $1500 to $3000.

In the end, installation fees are often worth it to have your new AC set up properly by a licensed pro. Doing it yourself to save money may seem tempting, but AC installation requires experience to do right. An incorrectly installed unit won’t cool efficiently and could end up costing more in repairs and energy bills.

When Is The Best Time To Replace A Central Air Conditioning Unit?

The best time to replace your central AC unit is typically when it’s not functioning properly anymore or is over 10 years old. While the average lifespan of an AC unit is 15-20 years, after a decade of use its efficiency starts to decline significantly, causing higher energy bills and repair costs.

  • AC Replacement During The Summer OR Spring Season

Replacing your AC in the spring or summer, just before the warm season, ensures you have a working unit when you need it most. However, AC installation companies are often very busy during these months, so their service may be delayed and rates higher. If you get a new AC in the summer, ask if the company offers any seasonal discounts or promotions to help offset the additional costs.

  • AC Replacement During Shoulder Seasons

The shoulder seasons of spring and fall can also be good times for AC replacement. The weather is mild, so you may be able to live without AC for a short period during installation. AC companies usually have more availability, allowing them to provide quicker service and possibly lower rates. They may run specials on AC tune-ups and replacements to fill their schedule between the busy summer and winter seasons.

Factors That Affect The Cost To Replace An Air Conditioner

The cost to replace your AC depends on several factors.

  • Size of the new unit
  • Brand and efficiency rating (SEER)
  • Where you live
  • Complexity of your Installation
  • Additional services

Size Of The New Unit

AC Replacement Cost factors

The biggest factor is the size of the new unit. If you have a large house it means a bigger AC is required which in turn increases the price tag. Installation of a new three-ton unit for a typical house will likely start around $3000 to $5000.

Brand And Efficiency Rating (SEER) 

The brand and efficiency rating (SEER) you choose also affects the overall cost. Higher SEER ratings, like 15 or 16, will cost more upfront but can save you money in the long run through lower energy bills. Name brands typically charge a premium over lesser-known brands.

Where You Live

Where you live plays a role in the replacement cost. Labor and material costs tend to be higher in some areas of the country. Permit fees required for installation may also vary regionally and locally depending upon your location.

Complexity Of Your Installation

Ac Replacement Cost by Installation factor

The complexity of your installation will impact the total bill. Simple swap-outs of existing units will be on the lower end of the cost spectrum. Full system replacements that require modifications to ductwork, electrical systems, or the roof or attic space in your home will add to the cost.

Additional Services 

Additional services like a multi-year labor or parts warranty, removal, and disposal of your old air conditioner, or yearly maintenance contracts will increase your replacement cost. But these types of add-ons often provide extra value and peace of mind.

Eventually, the cost to replace your air conditioner comes down to the specific options and features you choose for your needs and budget.

Types Of Air Conditioners

There are several common types of AC systems. The right system depends on factors like the size of your house and your budget.

  1. Central ACs
  2. Window air conditioners
  3. Ductless mini-split systems
  4. Evaporative or swamp coolers

Central ACs

Central ACs are one of the most popular options. They have an outdoor unit and an indoor air handler that distributes cooled air through your ductwork. Central AC systems are powerful enough to cool an entire house but tend to be more expensive.

Window Air Conditioners

Window air conditioners are a more affordable option if you only need to cool a few rooms. As the name suggests, they are installed in an open window with the cold air blowing into the room and the hot air exhausting outside. Window AC units are easy to install but may be an eyesore and less energy efficient than central air.

Ductless Mini-Split Systems

Ductless AC Replacement Cost

Ductless mini-split systems have an outdoor compressor and one or more indoor air handling units. They pump cooled refrigerant directly to air handlers in each room so no ductwork is needed. Ductless AC systems are good for additions or retrofits where installing ductwork isn’t feasible. They provide efficient zone control but tend to cost more upfront.

Evaporative Or Swamp Coolers

Evaporative or swamp coolers are an energy-efficient alternative in hot, dry climates. They cool the air by passing it over water-soaked pads, which lower the temperature through evaporation. Evaporative coolers only work in less humid weather but are much more eco-friendly and affordable than refrigerated air conditioning.

Weigh all these factors to determine which type of AC system is right for your needs and budget.

What Is The Average Lifespan Of An AC?

The average lifespan of a residential AC is about 15 to 20 years. As different types of AC units age, they become less efficient, and repair costs increase significantly.

When an AC nears the end of its lifespan, you’ll start to notice:

  • Higher energy bills from reduced efficiency
  • Noisy or strange sounds coming from the unit
  • Musty smells from excess moisture buildup
  • Parts frequently need replacement

If your AC is over 15 years old, it’s a good idea to start budgeting for a replacement. Newer units are far more energy efficient and you’ll save on utility costs while receiving tax rebates or credits in some areas for upgrading to an Energy certified model.

When the time comes to replace your air conditioner, get multiple quotes from HVAC companies for the best deal. A new central AC unit typically ranges from $3000 to $10000, depending on the size needed for your home. It may seem like a big upfront cost but it will pay off through lower bills and fewer costly repairs for years to come.

What Are Some Signs That My A/C Is Not Working Properly?

Reasons Why AC not working


If your AC isn’t cooling properly or running efficiently it’s probably time for a replacement. Some signs that your air conditioner needs to be replaced include:

Constantly Running But Not Cooling

Constantly running but not cooling. If your AC runs nonstop but can’t lower the temperature in your home, it likely needs replacement. The unit is working too hard but not effectively.

Strange Noises

Loud grinding, squealing, or rattling sounds coming from the AC usually mean it’s on its last legs. These noises indicate failing or broken components that will only get worse over time.

Musty Smells

If your AC is producing musty, mildew smells, it could mean standing water or mold buildup inside the unit. This can become a health hazard and requires replacement.

Higher Energy Bills

If your energy bills have spiked significantly over the past few months during AC use, your unit is likely inefficient and costing you money. Replacing it can improve efficiency and lower costs.

Age Of Air Conditioner

Most AC units last 10-15 years. If your AC is near or past this age range, replacement parts become scarce and repairs less effective. It’s best to replace the entire unit.

Repair Costs

If the cost to Repair your AC is more than half of its actual worth, it is better to replace it altogether. Multiple repairs on an older unit may not be worth the investment.

When in doubt, have an HVAC technician evaluate your AC unit. They can properly assess if replacement is needed and provide an accurate cost estimate for a new unit based on your home’s needs. Replacing sooner rather than later will save you money and ensure you stay comfortable all summer long.

How Long Does Air Conditioner Installation Take?

Air conditioner installation typically takes between 4 to 8 hours for a trained HVAC technician or team to complete, depending on the size and complexity of your unit.

Air Conditioner Installation Step-By-Step Process

AC Replacement process

  • The technician will shut off the power for safety before beginning any work.
  • If replacing an existing unit, the old one will be disconnected and taken out
  • A wall mounting plate and sleeve are installed and secured before the new AC unit is put in place. For window units, the mounting kit is installed in the window frame.
  • The new unit is set into the mounting plate and sleeve or window kit and fastened securely to prevent movement or falling.
  • The power is turned back on to connect the new wiring. The technician tests the new air conditioner to ensure it is properly functioning before leaving the job complete.

The total installation time depends on the type of air conditioner. A small window unit may only take a couple of hours, while installing a central air conditioning system with an attic fan coil unit and thermostat wiring may require most of the day. But in the end, you’ll have an efficient cooling system ready to keep you comfortable all summer long without wondering about “how long does it take to install AC units
