Should You Repair or Replace Your Air Conditioning Unit?
As a homeowner living in Louisville, one of the toughest decisions you’ll have to make about your air conditioner is when it’s time for a new unit. Although a new air conditioner can be a big investment, so can the costs of continuing to repair and operate an old, inefficient unit.
A central air conditioning system is an expensive investment, but most systems aren’t meant to last for much more than fifteen years. Ideally, it should be energy-efficient, while maintaining optimal comfort in every part of the home. Even with regular maintenance, you may reach a point where your system isn’t functioning well enough to keep your home comfortable during the hottest part of the summer. Here are a few signs that may indicate that it’s time to replace your central air conditioning system:
Replace Your Air Conditioner if it is Over 15-Years-Old
Around the 15 year mark, even an A/C unit that was properly maintained throughout its lifetime will struggle to run efficiently and effectively. There will be a point where the cost of service repairs and energy savings will outweigh keeping the old unit. If you find that it can’t keep you house cool, it’s overworking, or there are too many repairs needed – the best financial decision is to replace your older unit with a new, energy efficient air conditioner.
Replace Your Air Conditioner if the Repair Cost is Too High
Use the 5,000 rule when determining if the repair cost is too high. Multiply the age of the equipment by the repair cost, and if that exceeds $5,000, then replace the unit. If less, go ahead and repair it. This is a general guideline you can follow to give you an idea on whether repairing or replacing your equipment makes the most sense.
Replace Your Air Conditioner if it Becomes Inefficient
If your air conditioner has a low SEER rating, it can cost you a lot of money to operate it. Currently, newly manufactured air conditioners must have a SEER rating of at least 13. If your air conditioner’s SEER rating is below 13, you can cut back on your energy costs by replacing it with a new, more efficient unit.
Replace Your Air Conditioner if Repairs are Needed More Frequently
All A/C systems give out eventually, the question is when. With some systems, responsible upkeep and periodic maintenance can keep the A/C running well past its life expectancy. Usually, maintenance is more of a patch than a cure once the system has exceeded its full life expectancy. If the system now requires frequent repairs, such work is liable to be a drain on your wallet that won’t pay off in the long run.
Choosing Your Air Conditioner
Selecting an air conditioning system is an important decision and a large investment, but fortunately, it should pay for itself over time through energy savings. Over how much time? That depends on the type of air conditioning system you choose. Jarboe’s is proud to offer our clients the most energy‐efficient A/Cs available.

Our trained air conditioning experts will assess the situation and make sure you have the right air conditioning unit to keep you comfortable all season long.
Types of Central Air Conditioning Systems
There are two primary central air conditioner system configurations: a split system and a package system.
A split system includes an outdoor metal cabinet, which contains the condenser and compressor, and an indoor cabinet which contains the evaporator coil. The outdoor cabinet is located next to the home and the evaporator coil is located inside the home, above or near the air handler unit (furnace or blower). The indoor components may be located in a crawlspace, basement, attic, or closet. In split systems, the outdoor and indoor units must be properly matched in order to achieve their efficiency rating.
In a package system, all of the mechanical parts are housed in one cabinet, typically located outside the house.
In size and appearance, a heat pump looks like a central air conditioner. But unlike a central air conditioning system, which only cools a home, a heat pump provides both heating and cooling. Here’s another way to think of it. A heat pump is an air conditioner in the summer and a reverse air conditioner in the winter.
Most central heat pumps are split‐systems, which means they have an indoor unit and an outdoor unit. Some heat pumps are packaged systems, which means they usually have the compressor, condenser, evaporator coil, and fan located outdoors in a single cabinet. During the summer, a heat pump extracts heat from your indoor air, transfers the heat through refrigerant, and releases it to the outside. In the winter, the heat pump takes that hot air and, instead of venting it to the outside, pushes it back into your home. When an air‐source heat pump is heating your home, the cooling cycle is reversed. Whereas an air conditioner works just in the summer, the outside unit of a heat pump system works all year.
An air handler contains the components that move the air throughout your home, called the blower. It is usually set inside the home and operates with both the heating and cooling components of your HVAC system. If you take a quick look at an air handler, it may closely resemble a furnace. Air handlers can run with an air conditioner and contains the indoor coil, used to cool and heat your home depending on which system it’s running with.
If you have a heat pump outside your home, the air handler is likely the indoor component comprising your two-part, split system that keeps the indoor temperature of your home comfortable all year long. Most often, are located in the attic, basement or a dedicated closet, and may closely resemble the shape of a gas furnace. As its name suggests, an air handler “handles” the air inside your home and delivers warm or cool indoor air throughout your entire home. What would we do without delivery!
A Ductless Unit
A ductless heat pump or air conditioner typically consists of a wall-mounted indoor unit combined with an outside compressor. It’s most often used in a situation where a window AC unit or baseboard heating would be considered, such as a new addition to a house. But unlike window units, ductless units require only a very small hole to be drilled into the wall, making them less vulnerable to air leakage and security problems. Plus, they’re less visible and audible.
They’re also exceedingly energy-efficient. In an average house, you may lose 25% of your energy to ductwork. Simply by removing the ducts, you end up with a more efficient system. Ductless models also have inverter-driven compressors, which speed up and slow down based on the needs of the system instead of shutting off entirely like traditional HVAC compressors do.
Geothermal energy is up to 500% efficient. In other words, when you use one unit of electricity, you get up to five units back to condition the air in your home. That means that it takes less energy to keep you comfortable which saves you money. Plus, it can heat your water during the summer without additional energy usage. Since heating and cooling your home accounts for about 50% of your utility bills and water heating is another 14%, you can save big. Geothermal systems are so energy efficient that you may get your investment back in savings in as a little of 5-10 years, depending upon the efficiency of the system you are replacing.
