Summer in Indiana can range from a pleasant afternoon of sunshine to sweltering heat waves. Combine temperature swings with extreme humidity, an Indiana summer can be quite oppressive, and air conditioning becomes a lifeline.

With summertime approaching, this is no time to neglect your home’s air conditioner. To ensure your family is safe and comfortable, it’s time to tune up your air conditioner and ensure it’s in tip-top shape. All air conditioner repair and installation should always be performed by a professional HVAC technician to protect your home and your system.

Air Conditioner Repair in Indiana

Air conditioning in Indiana is a must-have. Without a proper AC unit, the summer quickly becomes unbearable. If your air conditioner goes out, it can be a costly replacement. Many of the most common air conditioner problems can be easily repaired before they turn into larger issues.

This is a common reason why your AC doesn’t seem to be working as well as it should. Most AC units need the filter replaced every 30-90 days. It’s always a good idea to start the spring season with a fresh AC filter. Some air filters can be cleaned and reused while others are disposable. Dirty filters reduce air flow and make your AC unit work harder, which increases your monthly bills.

If you have leaking coolant, this can be a potentially serious issue. Freon, which is the most commonly used refrigerant, is responsible for cooling the air. Without it, the unit will not work properly. Because any type of refrigerant is considered a hazardous liquid, leaks, levels, or maintenance of refrigerant should only be handled by an air conditioner repair specialist.

Most evaporator coils are located inside the unit, which protects them from common air conditioner repairs. However, if they are outside the unit, they can become dirty and corroded, which makes it difficult for them to work properly.

If you’re having a problem with leaks or refrigerant issues, you’ll likely end up with compressor issues as well. The compressor sends energy to the refrigerant and propels it through the coils to carry out heat exchange. A damaged compressor can be caused by too little (or too much) refrigerant.

Because all AC units create condensate, they need a proper drainage system. If your drain becomes clogged, it can cause serious issues to the AC unit itself, as well as to the area around the drain pan. Regular AC maintenance ensures your drain line is clear and your drain pan is properly used.

In an AC unit, there are many contactors and electrical connections for the compressor, motor, and condenser. If there’s arcing and pitting on the contactor, it becomes difficult for an electric current to start the motors.

Replacing the batteries in your thermostat can often fix what New Albany, IN homeowners think is an air conditioner repair.

Double check to be sure that your thermostat is working properly and replace the batteries if necessary.

Because your thermostat controls your HVAC system, sometimes the problem actually lies in the thermostat, not the whole unit.

If you suspect a thermostat issue, make sure it is level, not affected by direct sunlight, and set correctly.


Without capacitors, the motors that power the compressor and fans won’t work. The start capacitor sends a jolt to activate the motor, while the run capacitor provides a series of jolts to keep the motor working. The AC unit won’t run efficiently if either burns out.

Condenser coils are located outside your home with the compressor, so they can easily become dirty over the winter. Usually, a good hosing off is enough to get them clean, but if they’ve been neglected, an HVAC technician will have to clean them with a chemical cleaner.

If your AC motor isn’t running properly, there’s a good chance it’s due to the breakers and fuses. These components are designed to safeguard the AC unit’s motor or compressor from overheating. They should be checked and (if necessary) replaced regularly.

Air conditioning installation

The lifespan of an air conditioning unit is usually between 10-15 years. If your AC unit is reaching its limit, or if your air conditioner repair estimate is more than fifty percent of the cost of a new unit, it might be time for a new system.

New technology makes new AC units significantly more efficient, which means they use less energy to run. You will notice the savings on your monthly bills when you invest in a more efficient AC system. When it’s time for a new system, it’s important to know your options.

Ductless Mini Splits

One of the newer options in the U.S. market is the ductless mini system. While this has been popular in Europe and Asia for decades, it is just beginning to make a dent in the United States. This system allows you to control the climate room by room in homes without ductwork.

Split systems are one type of unit that will need air conditioner repair in New Albany, IN.

By installing a single condenser, you can connect several wall-mounted units in the rooms you use most. This allows you to cool or heat the rooms to your exact specifications. Keep the bedroom warm and the game room cool, all in one system. This can be an effective way to save money by only cooling the spaces you need.

Whether you choose a ductless system or a traditional AC unit, installation and future air conditioner repair of any kind still need to be performed by a professional to ensure proper working order and safety. 

Professional installation is usually required to maintain the warranty that comes with your unit purchase.
