Signs You Need AC Repair

It’s not always easy to tell if you need your system fixed.

Generally, you should call one of our Arlington AC repair contractors if your air conditioner exhibits any of the following signs:

  • Your unit blows warm or only slightly cool air – There are a few reasons this could be happening. If your air filter is too dirty, then it will obstruct the proper airflow your unit needs to cool properly. Replacing a dirty air filter is something homeowners do regularly with ease. If this isn’t the problem, you probably have a dirty condenser unit (outdoor unit) and you can often remove the debris yourself. If none of these are the issue, then your evaporator coil most likely needs a thorough cleaning and should be done by one of our Arlington AC repair pros.
  • Your unit makes irregular noises, including clunks, gurgles, or unusual clicks – All air conditioners make a little bit of noise. But if your unit’s noise level makes you turn the volume of your TV up, or you can hear it from another room, then it should get checked by a trained professional.
  • Your unit emits strange odors accompanied by poor airflow – If you’re getting strange smells when running the AC, you may need AC repair or a thorough duct cleaning. If you’re getting a musky smell of mildew, then you need a cleaning, but if you’re smelling something burning coming from your vents, then give your local Arlington AC repair specialists a call.
  • Your unit leaks excessively or drips from along the ducts – It’s possible you have a condensate line that needs repair, or maybe your air filter needs to be replaced as your unit isn’t getting proper airflow.

Our Northern Virginia AC repair professionals are proud to bring the very best in repair services and are available at any hour of any day. We have the experience and training necessary to work on any air conditioner make or model. At HVAC & Plumbing Unlimited, your happiness is our priority.

Central Air Conditioning Repair

There are various signs that your central AC unit may need to be fixed. While we’ve listed many of the signs above, we must go into further detail so that you can easily identify potential causes that require immediate repairs.

These include:

  • Leaks: When condensation forms inside your unit (which is a part of normal function), a drainage system directs the excess moisture. When this system is in jeopardy, pools of water can form at the bottom of and around your unit. These pools and any freezing along the sides of the unit or on its internal parts are often sure signs your central unit needs repair.
  • Strange odors: Odd smells that persist while your unit is running can be a sign that your coils are dirty or that the filter may be clogged. If you’re turning the unit on for the first time in the warmer season, somewhat of an odd musty smell is normal. However, if it persists for longer than a day, it’s a good idea to call in the pros.
  • Warm or slightly cool air: This is often a sign that the coolant in your system needs a recharge, and it is a cue to call in the professionals.
  • Irregular noises: Central air conditioning does make noise, but it often fades into the back of our minds within a few days of it running. If your unit is making enough noise that it calls your attention, it’s best to get it checked right away to avoid potential disasters.

Ductless Air Conditioning Repair

Ductless or “mini-split” AC systems come with their own unique challenges and issues, but the folks at HVAC & Plumbing Unlimited are more than equipped to handle any problem that may arise. These units share many of the same signs for repair as central air, but there are a couple to keep your eyes (and ears) out for.

These issues include:

  • Overheating: A running unit is likely to be slightly warm to the touch, which is normal. If it begins to give off excessive heat (like a hot hairdryer) and smells slightly of ozone, it’s a good idea to contact a trusted professional.
  • Leaking refrigerant: Just as a central unit can improperly drain condensation, so can a ductless unit. Both require a check. However, your ductless unit can potentially leak coolant, which is a sign of a much larger issue and requires immediate service.
  • System freezing or presence of ice: Many problems can lead to a sudden formation of ice or frost on your ductless system, including airflow complications, refrigerant issues, and even a system that just isn’t cleaned often enough! No matter the cause, you can count on the HVAC & Plumbing Unlimited repair team to find the root of the issue and get it fixed right away.
  • Sudden rises in energy costs: Ductless cooling systems boast exceptional energy efficiency in addition to low cooling costs—it’s one of the big reasons why they’re so popular. When your bill suddenly shoots up by even tens of dollars, you can bet there’s an issue. Call on our team to restore the efficiency of your system.

Heat Pump Repair

Our Northern Virginia AC repair experts have been handling heat pump systems for decades. We’ve seen and fixed it all. These systems, like other types of air conditioners, can encounter some fairly unique problems.

If you enjoy the benefits of a heat pump in your home, be wary of the following:

  • Mode jamming: Since a heat pump can serve as both a cooling and heating system, it features mode swapping. Occasionally, it can get stuck in one or the other—you’ll often notice this just as the seasons turn when you’re trying to go from “heat” to “cool.” The problem lies with your reversing valve, but the fix is a fairly simple one for our professional repair technicians.
  • Puddling water: This can be accompanied by ice or frost, much in the same way as a ductless system. Undue condensation typically comes from a condensate system malfunction but can also arise when your coils or overall unit hasn’t been cleaned or serviced frequently enough. Especially with heat pumps, semi-annual HVAC maintenance is critical.

Air Conditioning Repair FAQs

Should I repair or replace my air conditioning system?

Most air conditioners last 8 to 12 years. If your air conditioner is less than eight years old and has only had relatively minor problems, such as a faulty contactor, a start capacitor failure, or a leaking refrigerant line, repair is likely the best option. If your air conditioner is over eight years old, needs frequent repairs, or a costly part has failed, like the compressor, blower motor, or condenser coil, an AC replacement may be the more cost-effective long-term option. The HVAC & Plumbing Unlimited experts can discuss your repair or replacement options and give you honest, realistic recommendations tailored to your needs and budget.

What should I try before calling for AC repairs?

To avoid an unnecessary service call:

  1. Check that the thermostat is on, working properly, and set to cooling mode.
  2. Check that the air filter is not dirty or clogged, and make sure none of the AC vents are blocked by curtains, furniture, or other items.
  3. Check the service panel to make sure the AC breakers have not tripped. You can reset the air conditioning system by turning the breakers off, then back on.

If the system still does not run correctly, call our HVAC & Plumbing Unlimited experts for AC repairs.

Why is my air conditioner so loud?

Some noise is normal when using your air conditioning system, but if it is excessively loud, the sound level increases, or you notice new noises, it may be best to have the system inspected. Sounds like grinding, screeching, or buzzing are especially problematic because they may indicate mechanical damage, blower fan problems, or compressor damage.

What causes the evaporator to freeze?

If you notice frost or ice on the evaporator coil, refrigerant lines, or compressor casing, it can be caused by:

  • A clogged air filter
  • Airflow problems
  • Low refrigerant
  • Dirty coils
  • A faulty compressor

To thaw your system properly and find the cause of the problem, call our team at HVAC & Plumbing Unlimited for help anywhere in Arlington or Northern Virginia.
