If you're in the market for a new AC unit, you've got several options to consider. There are three main types of AC units: window units, portable units, and central air systems.
Window units are a popular choice because they're relatively inexpensive and easy to install. They're also a good option for small spaces or rooms.
Central air systems, on the other hand, are a more complex and expensive option, but they provide consistent cooling throughout the entire house. They're ideal for larger homes or those with multiple levels.
The size of your AC unit is also an important consideration, and it's essential to choose a unit that's the right size for your space.

Understanding Your AC Needs
To determine the right AC unit for your home, consider the tonnage you need, which refers to the amount of heat the unit can remove in one hour, not its weight. A one-ton unit can remove 12,000 British Thermal Units (BTUs) of heat.

A unit that's too small won't cool efficiently, while one that's too large will cycle on and off frequently, wearing it out faster. Oversized units also struggle to remove humidity from your home efficiently.
Your local climate, home size, insulation, and window size all impact the tonnage you need. A technician should examine your home's specific needs before recommending an AC unit.
A well-maintained AC unit can last anywhere from 15 to 20 years. However, a unit that's too large for your home is likely to fail faster than a properly sized one.
Getting the right-sized unit for your home can save you energy costs and extend the unit's lifespan.

Reduce Energy Bills
Replacing your old AC unit can have a significant impact on your energy bills. Approximately 50% of a home's energy bill is attributed to heating and cooling costs.
Older units are less energy efficient than newer models, which means you'll see the difference in your monthly energy bill.
The U.S. Department of Energy has increased the minimum efficiency standards over the years, so even if you maintain your old AC unit, it will always be less efficient than a modern system.
A higher SEER rating indicates greater energy efficiency, and the U.S. Department of Energy requires new air conditioner units in the northern half of the U.S. to have a SEER rating of at least 14, and in the southern half, a rating of at least 15.
Purchasing a new and more efficient unit could be a worthwhile long-term investment if you see your energy bills creeping up.

Repair vs Replace
If your air conditioner is having problems, you might be wondering whether to repair or replace it. A repair is usually the more cost-efficient option if the problem can be fixed for less than 50% of the replacement cost. If you've had your AC for less than a few years and are only experiencing a one-off breakdown, a repair might be a better option.
However, if you've had the same unit for over a few years and are experiencing month after month of unexpected breakdowns, it might be better to replace it. This is especially true if the repair costs are approaching or exceeding 50% of replacement costs.
Here are some signs that it's time to replace your AC unit:
- If the repair costs are more than 50 percent of the price of a new air conditioner.
- If your unit is over 10 years old and has recurring issues.
- If your system is not operating efficiently, resulting in high utility bills.
Should You Repair Your HVC System?
If your HVAC unit can be repaired, that's almost always more cost-efficient than buying a new unit. Plan to call a tech for a repair in these circumstances:
- If your pilot light won't stay lit.
- If your unit has a leak.
- If the unit's fan won't stop running or if your system gets "stuck" in one mode.
- If your system is over 10 years old and has recurring issues.
- If high utility bills suggest your system is not operating efficiently.
- If repair costs are approaching or exceeding 50% of replacement costs.
If you encounter a problem like your AC is running but not cooling or your furnace is running but not heating, you might be able to repair it, or you might be looking at a situation where your system needs to be replaced.

The "5,000 rule" is a good guideline to consider: multiply the age of the unit by the repair cost, and if the total is less than $5,000, you should consider repairing it. If it exceeds $5,000, it might be better to replace it.
You should also consider the frequency of repairs: if the answer is "yes", you should consider replacing the air conditioner. Otherwise, it's best to repair the equipment.
Here are some signs that you should consider replacing your unit:
- The warranty is expired or invalid.
- The unit is over 10 years old.
- The unit is over 15 years old.
- You've had the same unit for over a few years and are experiencing month after month of unexpected breakdowns.
- The repair costs are more than 50 percent of the price of a new air conditioner.
- You're experiencing high energy bills, and the system is becoming less efficient.
If you're unsure whether to repair or replace your HVAC system, consult with a professional to determine the best course of action.
System Mismatch
A mismatched AC system can cause more problems than you might think. The indoor and outdoor units need to be compatible to operate efficiently.
If you have a mismatched system, it's likely to break down more often. This can lead to costly repairs and even more frequent breakdowns.
A mismatched system won't run as smoothly as it should, which can make your home feel uncomfortable and even unhealthy.
AC System Setup and Maintenance
A new AC unit is a significant investment, and it's essential to get it right. You can expect a new system to last anywhere from 15 to 20 years with adequate upkeep and proper maintenance.
To ensure your AC unit lasts as long as possible, regular tune-ups and maintenance are crucial. In fact, some people think that once the unit stops working for the first time, it's time for a new one, but this decision plays a significant role in determining how long an AC unit lasts.
Here are some essential factors to consider when it comes to AC system setup and maintenance:
By considering these factors and performing regular maintenance, you can help extend the life of your AC unit and keep your home cool and comfortable.
System Setup Requires Removal
In some cases, your HVAC system setup might require removal of the entire system to replace just the air conditioning. This can happen when the evaporator coil is located in a hard-to-reach spot.
The evaporator coil is often situated in areas where it's difficult to access, such as in concrete slab homes. In these cases, our crews must remove the existing furnace to change the coil, then re-install the furnace.
In areas like Dayton, Ohio and Cincinnati, Ohio, we see a lot of concrete slab homes, which can lead to this issue. This can add extra labor costs to the job.
Replacing both units at the same time can be a cost-effective solution in these situations. This way, you can avoid paying a crew to remove the water heater again in a few years.
For example, if your HVAC setup requires the water heater to be removed for the AC replacement, it's likely to happen again when the furnace needs to be replaced. This can save you hundreds of dollars in labor costs.
In concrete slab homes, the downflow furnace often sits on top of the evaporator coil, making it necessary to remove the entire system.

Factors Influencing Air Conditioner Lifespan
A mismatched AC system can lead to issues and a shorter lifespan. A system with incompatible indoor and outdoor units will not run smoothly and is more likely to break down.
Proper installation is crucial for a long-lasting AC system. If installed correctly, it can help extend the lifespan of your unit.
Regular maintenance is essential to keep your AC system running efficiently. With adequate upkeep, you can expect a new system to last anywhere from 15 to 20 years.
Some factors that influence the lifespan of your system include:
- Proper installation
- Amount of month-to-month wear-and-tear and personal comfort settings within your home
- Climate factors, such as extreme cold or high humidity
- Air quality factors (salty sea breeze or other corrosives in the air)
Financial Considerations
If the price of a new AC system is right, it's a no-brainer to replace your old one. King Heating and Cooling regularly offers special deals on new AC installations, and you may even make up the cost gap in energy savings.
Replacing your old AC system can also make sense if you need something more efficient, as an older system can lead to eye-popping electricity bills. Regular maintenance can only do so much, and a new system may be necessary for energy efficiency alone.
If you're on a tight budget, you might need to make a tough choice and replace only the AC unit that urgently needs it. Replacing your AC and furnace separately will cost more in the long run, but sometimes you have to prioritize your expenses.
Insufficient Funds
Replacing your air conditioner can be a significant expense, and it's not always possible to afford it at the same time as other necessary repairs. You may find yourself in a situation where you can't afford to replace both your indoor and outdoor units simultaneously.
If you're on a tight budget, it's perfectly fine to replace the unit that needs it most first. According to King Heating and Cooling, replacing the unit that urgently needs it may be a more feasible option, even if it means replacing both units separately in the long run.
Replacing one unit at a time may seem like a more affordable option, but keep in mind that it can still be expensive. However, if you can't afford both units right now, it's better to prioritize the one that's causing the most problems.
Here are some possible scenarios to consider:
In any case, it's essential to weigh your options carefully and consider your financial situation before making a decision.
