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 these 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, 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 is the issue, then your evaporator coil most likely needs a thorough cleaning, which should be done by one of our Arlington AC repair pros.
- Your unit makes odd noises, including clunks, gurgles, or unusual clicks: All air conditioners make a 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 musty smell of mildew, you need a cleaning, but if you’re smelling something burning coming from your vents, call your local Arlington AC repair specialists immediately.
- Your unit leaks excessively or drips from along the ducts: You could 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 provide the best in repair services and are available at any hour of any day. We have the experience and training to work on any AC make or model. At HVAC & Plumbing Unlimited, your happiness is our priority.

Central Air Conditioning Repair
Several signs indicate 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 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 signify that your coils are dirty or that the filter may be clogged. A somewhat musty smell is normal if you’re turning the unit on for the first time in the warmer season. However, if it persists for longer than a day, it’s a good idea to call the pros.
- Warm or slightly cool air: This is often a sign that the coolant in your system needs a recharge, and it’s a cue to call 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 you may encounter. 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 starts giving 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 isn’t cleaned often enough. No matter the cause, you can count on the HVAC & Plumbing Unlimited repair team to find the cause of the issue and fix it 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 main 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 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. Like other types of air conditioners, these systems can encounter some 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 like 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, semiannual HVAC maintenance is critical.

Common questions about AC Units that Need Repairs
Should I repair or replace my air conditioning system?
Most AC units last 8 to 12 years. If your AC is under eight years old and has minor issues, repair is usually the best option. However, if it’s over eight years old, needs frequent repairs, or has a costly failure, replacement may be more cost-effective. HVAC & Plumbing Unlimited can help you decide.
What should I try before calling for AC repairs?
- Check that the thermostat is set correctly.
- Ensure the air filter is clean and vents are unobstructed.
- Verify the AC breakers are on. If the system still doesn’t work, call us.
Why is my air conditioner so loud?
Some noise is normal, but loud or unusual sounds like grinding or buzzing may indicate a problem. Have your system inspected by HVAC & Plumbing Unlimited.
What causes the evaporator to freeze?
Ice on the evaporator coil may be caused by a clogged air filter, airflow problems, low refrigerant, dirty coils, or a faulty compressor. Call HVAC & Plumbing Unlimited for help.
