Choosing between AC repair and replacement shouldn’t be a source of anxiety. There are several signs that can help you make the best choice. You’ll need to pay attention to how the AC behaves and how much it costs you.
You Have an Outdated System
Air conditioners will last for many years as long as they receive regular care and maintenance. This includes professional cleanings and periodic filter changes. But even with the utmost care, most cooling systems only last about 15 years. If yours is nearing this age, it’s time to consider a replacement.
Your Energy Bills Keep Rising
If your energy bills keep going up despite no changes in your cooling habits, the problem may stem from the air conditioner. This is because cooling systems degrade over time, causing them to use more energy to cool the house. In many cases, the only way to use less energy is to do a replacement. An expert can help you decide whether a repair or replacement will work best for your situation.
Uneven Cooling Throughout the Home
Your air conditioner should be able to cool the whole house without any hot spots. If it fails to do this, it could be the result of a clogged filter, which simple maintenance can fix. It could also be the result of blocked ducts or low refrigerant levels, which a repair can resolve. However, if the problem stems from an undersized unit or aging components, a complete replacement will be necessary.
Strange Noises or Odors Coming from the AC
Your air conditioner shouldn’t make a lot of noise. A low hum may occur when it runs, but this is very normal. If you hear any clinking, rattling, banging or screeching, turn it off right away. These sounds indicate a serious problem, like a loose part or a broken motor. You should also switch it off if you notice any weird smells, like burning wires or mold. Some of these issues are fixable with a repair, but in most cases, it’s best to do a full upgrade of the whole cooling system.
The System Struggles on Hot Days
A well-functioning AC will perform with peak efficiency, even on the hottest of days. If it starts to lag, this is a red flag. It most likely means the system is starting to near its end of life or it has lots of worn-out components. It could also mean the unit isn’t the right size for your house. An upgrade will restore consistent comfort and improve overall energy efficiency. Your home will be cool during high temperatures and you’ll also enjoy lower energy bills.
The AC Keeps Breaking Down
If you find yourself constantly having to call a repairman, this is a big sign the AC is on its last legs. Fixing small problems like clogged filters or a faulty thermostat is quite normal and usually isn’t expensive. However, if you’re constantly having to replace parts or recharge the refrigerant, the cost of the repairs will add up. It might be time to stop pouring money into the old unit and instead put it toward a new one.
You’ve Made Recent Home Additions
If you want to make your home bigger, you’ll need to speak with an HVAC technician beforehand. The old AC might not be big enough to cool all the new space. This is why HVAC sizing is so important. A technician will check the capacity of the AC to determine whether it can handle the increased load. For many projects, the only way to achieve consistent comfort is to get a bigger cooling system.
Poor Indoor Air Quality
Air conditioners have a direct effect on indoor air quality. The air filter specifically filters out dust, allergens and other particles. You’ll need to keep the filter changed regularly to ensure it captures contaminants effectively. If you keep noticing more dust around the house, just check the filter. It’s probably dirty. Clogged filters make the AC work harder than normal, leading to premature repairs and breakdowns. They also impact humidity levels by restricting airflow. This can result in excess moisture and mold growth, which can be detrimental to your health and comfort. If you keep experiencing air quality issues, it might be best to upgrade the AC with a version that has advanced filtration. Many newer models come with HEPA filters and built-in dehumidifiers.
What Is the $5k Rule?
A lot of experts recommend using the $5k rule to decide between AC repairs and replacements. This calculation involves taking the age of the unit and multiplying it by the cost of the repair. If the number exceeds $5,000, a replacement is usually the smarter choice. Let’s say you have an air conditioner that is seven years old and keeps breaking down due to a failing compressor. To repair the system, it’s going to cost $850. So for the $5k rule, you multiply 7 by 850, and you get $5,950—meaning it’s more cost-effective to replace the unit.
What to Look for in a New Cooling System
Picking a new cooling system for your home is a big decision. It requires careful consideration to ensure you install the right model at the right size. Here are some of the most important factors to consider when making a selection.
High SEER Rating
You should always look at the Seasonal Energy Efficiency Ratio (SEER) for an air conditioner. The higher the rating, the less energy the unit uses. Modern versions often fall between the 13–20 SEER range. Higher SEER models may be more expensive initially, but they end up saving money on energy costs because of their enhanced efficiency.
Smart Thermostat Compatibility
You want an air conditioner that can sync with home automation systems, like smart thermostats. This will give you remote access to your home’s cooling system at all times, regardless of your location. Smart thermostats usually come with a wide range of advanced settings. For example, you can set temperature schedules for different times of day to achieve optimal comfort and energy efficiency. They often integrate with sensors to monitor occupancy and humidity. When used strategically, you can save up to 20% on cooling costs. Many versions even provide real-time energy reports, so you can further reduce your carbon footprint.
No Ducts? No Problem
Does your home have outdated, leaky air ducts? Or maybe it doesn’t have any ductwork at all. In these scenarios, it’s still possible to enjoy cool living spaces during the warmest of weather. All you need is a ductless mini-split system. We find that these units work best in homes with older construction or room additions. They also perform exceptionally well in spaces that are difficult to cool with traditional systems. Ductless models come with faster, cheaper installations because there is no need for ductwork. Plus, you can use them year-round for both heating and cooling.
