8 Signs Your Air Conditioner is About to Fail in North Texas

Read this guide for 8 key signs that your air conditioner is about to fail, and to learn when you might need an AC replacement.

When your AC is struggling its way through another sweltering North Texas summer, you're probably going to know about it. A failing HVAC system is usually characterized by several small problems, which you can catch before it completely breaks down. Your air conditioner might start making unusual noises or blow warm air, or you might notice that your energy bills are higher than normal with no obvious reason why.

If you catch these warning signs early, you can avoid the dreaded emergency breakdown scenario and sidestep expensive repairs.

Key Takeaways

• Rising energy bills, uneven cooling, strange noises, and reduced airflow are often clear signs that your air conditioning system is on its way out.

• Older units using R-22 refrigerant are going to cost you more in repairs every year.

• If your AC is constantly breaking down, it's time to consider a HVAC replacement.

• Regular HVAC service from a reputable company like Koala-T is the best way to catch problems before they turn into major money pits.

1. Your Energy Bills Keep On Rising

One of the biggest signs your air conditioner is about to fail is a noticeable hike in your energy bills.

You'll probably notice this during the peak cooling season in North Texas when your AC is running non-stop to keep up with the triple-digit temperatures. If your energy bills keep climbing every month, even though you're not touching the thermostat, your HVAC system is probably struggling to keep up.

It's all too easy to ignore rising energy costs for months because your air conditioning unit is still cooling the house. But if you're noticing higher energy costs, we strongly recommend getting your HVAC system serviced to check that it's operating properly and avoid the hassle of an emergency breakdown.

2. Certain Rooms Feel Way Warmer Than Others

Uneven cooling is another clear sign that your HVAC system is in trouble. You might notice that one bedroom is nice and cold while another room is still warm, no matter how low you turn down the thermostat.

Several HVAC issues can cause uneven cooling, including:

• Weak airflow

• Damaged air ducts

• Low refrigerant levels

• Frozen evaporator coil problems

Modern air conditioners should be able to keep your house at a consistent temperature. If your AC unit is having trouble cooling certain rooms, it can be a sign that it needs to be repaired, or even that it's on its way out.

Give us a call if you're concerned. We'll send out a Koala-T HVAC technician who can take a look at the whole cooling system and help you decide whether a few repairs or an entirely new air conditioner makes more sense for your home.

3. Your AC Runs Constantly, Day And Night

During North Texas summers, your AC unit is obviously going to run longer during the afternoons. But if it never shuts off, this suggests that your system is struggling to keep up.

Several problems can trigger non-stop AC operation, including:

• Dirty coils

• Refrigerant leak issues

• Compressor failure

• Poor airflow

• Aging parts

If your AC is running all day and night, get it fixed ASAP. Waiting too long will only push the whole unit towards complete mechanical failure.

4. Strange Noises Are Getting Louder And Louder

It goes without saying that your air conditioning system should never sound like a construction site, so if you hear banging, grinding, rattling, squealing, or buzzing sounds, this usually means there's something seriously wrong inside the unit.

Common causes of unusual noises inside an AC system include:

• Loose fan blades

• Compressor failure

• Motor damage

• Failing condensate pumps

• Debris inside the outdoor unit

In this case, it might not make sense to just keep shelling out money for repairs if the system keeps on deteriorating.

5. You're Getting Warm Air Coming Out Of Your Vents

Warm air from your air conditioning unit during a North Texas heatwave usually means big trouble.

A healthy AC unit should be pumping out cool air within minutes of turning it on. If your vents are pushing out warm air instead, there's likely an internal issue that needs addressing.

Low refrigerant levels often cause this problem. A refrigerant leak can prevent the system from pulling heat out of the air properly. And if you have an older unit that still relies on R-22 refrigerant, you've got an added hassle: affordable refrigerant is getting scarcer and scarcer by the year.

R-22 is no longer produced because of environmental concerns. As supplies keep dwindling, repairs on systems that rely on R-22 are getting more and more expensive.

If your air conditioner still uses R022, you should probably strongly consider replacing it instead of throwing your money into repairs. A new system will give you a noticeable boost in energy efficiency, which will lower your energy costs and provide the reassurance of reliable performance during the hottest summer months.

6. There are Signs of Moisture Around The Unit

Moisture around your AC unit can be another sign that your cooling system isn't working as it should.

Your air conditioner naturally creates condensation as it cools your home, which is then safely removed by the drain line. But when the drain line gets clogged, water starts to collect around the unit.

If you notice this problem, you might also see:

• Mold growth on nearby surfaces

• Higher humidity inside your home

• Water damage to the surrounding area

• Frozen coils

• A failing condensate pump

It's easy to mistake these warning signs for a plumbing issue, when in reality, it's often the air conditioning system that's the culprit, and you'll need to contact a technician, like the Koala-T team, who specializes in HVAC repair.

7. The Unit Needs Frequent Repairs

We all know that occasional repairs are just part of life, but if your HVAC system needs repairing regularly to keep functioning properly, this usually signifies a major problem.

Aging AC systems often suffer from:

• Compressor failure

• Refrigerant leaks

• Frozen coils

• Weak airflow

• Mechanical failure

At this stage, it's probably time to start thinking about replacing the unit altogether.

If you need a second opinion, contact us at Koala-T. We help North Texas homeowners compare air conditioner replacement costs with repair costs, so you can make the right choice for your budget and your home comfort.

8. Your System Is Nearing the End of Its Lifespan

Typically, air conditioning systems last for about 20 years, or 10 to 15 years in North Texas. Living in a hot climate means your AC has to work a lot harder and for longer periods, which shortens its lifespan.

If you're dealing with higher energy bills, along with any of the other warning signs we've listed above, your air conditioner has probably reached the end of its usable life.

Upgrading to a new system will give you the benefits of better heating and cooling performance and stronger airflow. Plus, you'll enjoy lower energy costs and improved air quality.

Don't Wait Until Your AC Completely Packs Up

North Texas summers put a huge strain on every HVAC system, and before you know it, small problems can quickly become major breakdowns. That's why it's worth addressing an issue as soon as it presents itself.

If your AC is showing any of these warning signs, Koala-T can send an HVAC technician to inspect your system and explain your options, helping avoid any surprise breakdowns when you need your AC the most.
