Why Is My Air Conditioner Still Not Working After a Repair?

Imagine it’s an 85-degree Columbus summer day, and you’ve just had your AC repaired only to find it broken again. If you’re dealing with a broken air conditioner even after a service call, it’s time for professional AC repairs from a qualified expert.

Explore some common reasons why AC problems return, when to call for a second opinion, and when you may want to consider a replacement rather than AC repairs.

Common Reasons AC Problems Come Back

From loud AC noises to a system that’s running but not cooling, there are a variety of AC problems that can return after repairs. Discover some common reasons why AC problems might come back.

Old or worn AC unit

Most modern air conditioners have a lifespan of around 15 to 20 years, while older units typically last 10 to 12 years. If your air conditioner is nearing the end of its maximum lifespan, it may experience frequent breakdowns even after a repair. While good maintenance extends the lifespan of your AC, you may want to consider a replacement if your broken AC unit is more than 15 years old.

Refrigerant leaks

Refrigerant is the liquid inside your air conditioner that facilitates the heat transfer process, carrying heat from inside your home and moving it outside to cool the indoor air. In a well-functioning AC unit, the level of refrigerant should stay consistent inside the system. However, a minor leak can lead to low refrigerant levels, which can cause a variety of AC problems. 

Low refrigerant can lead to the AC blowing warm air, longer cooling cycles, and other issues that may cause motors and fans to burn out. It can also strain the compressor, leading to a breakdown. If your previous AC repair person fixed one of these issues but missed the refrigerant leak, the problems may return.

Handling refrigerants can be hazardous to your health and the environment, so leaks in your air conditioner require emergency repair by a professional.

Thermostat problems

In some cases, the thermostat may be the cause of the issue rather than the AC. A broken or miscalibrated thermostat may signal the unit to run longer or shorter cycles, or fail to turn on when you need cooling. Even with an AC repair, the unit may not function properly if it’s receiving incorrect thermostat signals. 

Wrong AC size

If your air conditioner is the wrong size for your home, it may continue to break down even after repairs. An AC unit that’s too small will work too hard to cool your home, potentially overheating or failing. A system that’s too large may short-cycle or not turn on.

When To Consider Getting a Second Opinion From Certified AC Experts

If you’re considering a major air conditioner repair or replacement, it’s a good idea to get a second opinion from a certified AC pro. Contact a professional if you’re facing the following issues.

Problem returns after repairs

If your AC is not working after maintenance, it’s time to contact a qualified pro. Your previous repair person may have missed the issue, or the repair may have been performed incorrectly. Getting a second opinion from a certified AC expert helps ensure the job is done right. 

You’re not sure what’s wrong

For persistent AC issues that are difficult to diagnose, it’s best to call a certified technician. The team at Dugan Air has the tools and expertise to identify and repair complex AC problems, so your AC is fixed right the first time.

After your AC is repaired, your pro should perform a service test to check that everything is working properly. Be aware of any unusual noises, odors, or liquids on or around your AC, which may indicate an incomplete AC repair.

When It’s Time To Consider a Replacement

Practicing regular AC maintenance is the best way to keep your system running smoothly. However, even the best AC units eventually wear out. If you’re dealing with one of the following situations, it may be time to consider an AC replacement.

Old air conditioner unit

If your air conditioner is nearing the end of its expected lifespan (typically 15 to 20 years), it may be more efficient to replace it rather than repair it. Upgrading to an Energy Star-rated air conditioner can save energy and reduce your cooling costs.

Frequent breakdowns

When an air conditioner is breaking down regularly, it may no longer be worth investing in repairs. Although it can be frustrating to replace an AC unit that you’ve already spent money fixing, it’s likely more efficient in the long run to buy a new unit. A reliable unit helps keep your home cool and comfortable.

Costly repairs

Consider the cost of the repair against the long-term value of the unit. If you have a relatively new unit with minor damage, the repair may be worthwhile. However, if you need to make an expensive repair or replace major parts on an old unit that’s already showing signs of wear and tear, it’s probably better to invest that money into a replacement AC.
