Signs You Need AC Repair Service
- No cool air: If you’re not getting any air at all, it could be a problem with your blower fan. But if the air isn’t cooled, then it could be your evaporator coil or an air filter that needs a cleaning.
- Poor airflow: If you’re getting some air, but not the amount that you’re used to, then it’s likely your ducts. You could be losing some treated air, or maybe there’s something in your ductwork that’s impeding your airflow.
- Unusual noises: All AC units make some noise, but if you’re hearing something that’s new, abrupt, or particularly loud, then call in our Charlotte AC repair experts.
- Strange odors: A burning smell coming from your vents in the summertime usually means something is wrong in your unit.
- Accumulation of moisture: As cooling air requires a bit of condensation, you’ll sometimes get mold and mildew growth in your unit or ductwork as a result.
- Faulty thermostat: If your AC isn’t cooling to the desired temperature, it could be your thermostat that’s the culprit.
- Excess cooling costs: When your AC gets older, it might cool to the amount you want but may need more electricity in order to do so, which will cost you.
- Frequent cycling: Short-cycling is the result of a compressor that’s on the fritz. Either that or your AC could be too big for your home.
- Extended cooling times: If it’s taking longer to cool than usual, call in our AC repair specialists to take a look and see what’s going on.
- Reduced indoor air quality: Like efficiency, older AC units can negatively affect your indoor air quality in a few ways, so it’s good to subscribe to routine AC maintenance.
Early detection and action can prevent more severe problems from occurring and save you money on your energy bills. That’s why it’s very important to call the expert team at Roby as soon as you notice any of these issues. After diagnosing the source of the problem, we will advise you on your best options for resolving the issue. Whether you choose to repair or replace the air conditioner, we’ll go to work to complete the job in an efficient and cost-effective manner.
Why Is My AC Not Blowing Cold Air?
- Dirty air filter: One of the most common reasons that you aren’t experiencing proper airflow from your AC unit is due to a dirty air filter. When there’s too much debris in your filter, it does not allow room for air to move over the evaporator coils, which can cause them to frost over, restricting the flow of air.
- Control board malfunction: The control board works together with the thermistor to tell the compressor to turn off or on based on the temperature you have selected on your thermostat. If the control board is defective in any way, no power can be sent to the compressor, resulting in the lack of cold air.
There are other reasons why your AC may not be working properly, and it’s always best to consult with an experienced air conditioning technician before trying to troubleshoot anything on your own.
Air Conditioning Repair vs. Replacement
When your AC goes down, there are a couple of options unless you want to brave the summer heat without AC. You could either replace the unit or consider AC repair. While repair might at first seem like the more cost-effective decision, it’s actually more expensive in the long run in the following situations.
1. Your AC is older than 10 years: On average, an AC unit usually survives for eight to 12 years, depending on how it’s used, the surrounding environment, and how often it’s maintained. If it’s much older than that, don’t sink more money repairing a dying unit and make the switch.
2. It needs one repair after another: Our Charlotte AC repair team is always willing and able to come in and get your AC back in working order, but if you need us to fix it every year, those repair calls will add up. At some point, another AC repair is going to cost more than replacement when you consider a new unit is on the horizon so consider replacement before it gets to that point.
3. The unit required R-22 Freon: Because of the 2020 Freon ban, AC units that depend on the banned coolant are only going to get more expensive to run as Freon becomes increasingly scarce.

Frequently Asked Questions for Local AC Repair
How fast can you arrive in Dilworth during peak summer?
In many cases, we can reach Dilworth quickly because we are based nearby and dispatch throughout the Charlotte metro every day. During peak summer demand, arrival time depends on call volume and weather conditions, but we prioritize no cooling situations and homes with vulnerable occupants. When you call, we will confirm the earliest available appointment window and let you know what to do to stay comfortable and protect your system until we arrive.
If your AC is completely down, turning off the system and keeping blinds closed can help reduce heat gain. If you see ice on the indoor unit or refrigerant lines, turn the system off and set the fan to ON to help thaw the coil, then contact us for service.
Yes, we work to provide same day AC repair across Ballantyne and surrounding neighborhoods whenever scheduling allows. Same day availability is strongest when you call earlier in the day, especially for urgent issues like no cooling, water leaking from the air handler, or unusual noises coming from the outdoor unit.
Even if we cannot complete the full repair the same day due to parts availability, we will still focus on diagnosing the problem quickly and recommending the most reasonable next steps to restore comfort as fast as possible. If replacement is the safer option, we can also guide you through equipment choices and timelines.
We service and repair all major air conditioner and ductless mini split brands commonly found in University City homes, apartments, and townhomes, including Trane, Carrier, Lennox, Goodman, Rheem, American Standard, York, and Daikin. Our technicians also work on many other brands and older systems, even if the equipment is not one of the most common names.
If you are unsure what you have, check the data plate on the outdoor unit or indoor air handler for the brand and model number. Either way, we can identify the system during your visit and recommend the right repair or maintenance plan to keep it running efficiently in Charlotte heat and humidity.
You can call any time. Our phone line is staffed around the clock so you can reach our team nights, weekends, and holidays. If you have urgent issues such as no cooling, electrical burning smells, loud grinding or banging noises, or water leaking that could damage floors or ceilings, we will help triage the situation and dispatch as soon as possible.
If you smell gas, leave the home and contact your gas utility or emergency services first. For electrical concerns like sparking or smoke, shut off power to the system at the breaker if it is safe to do so and call right away.
In many cases, the diagnostic fee can be credited toward the repair when you approve the recommended work during the same visit. This allows you to put that diagnostic cost toward restoring comfort instead of paying it separately.
Because pricing and eligibility can vary by season, repair type, and any active promotions, we will always explain the options clearly before work begins. If you have questions about how the credit applies, our team can confirm details when you schedule or before you approve the repair.
Yes. We service many Uptown properties where equipment is located on rooftops, terraces, or mechanical rooms. Our technicians follow safe access procedures and are experienced with the challenges that come with rooftop condensers and packaged equipment, including building access requirements, freight elevator scheduling, and coordination with property management.
When you schedule, let us know if there are access instructions, gate codes, parking restrictions, or required check in procedures. That helps us arrive prepared and complete the diagnosis and repair as efficiently as possible.
Start with a few quick checks. Confirm your thermostat is set to COOL and the temperature is set below the current indoor temperature. Replace the air filter if it is dirty, and make sure supply and return vents are open and not blocked by furniture or rugs.
If you see ice on the indoor coil, copper refrigerant lines, or the outdoor unit, turn the system off and set the fan to ON to thaw the coil. Frozen coils are often caused by restricted airflow or low refrigerant. Continuing to run the AC while frozen can lead to compressor damage, so it is best to shut it down and call for service.
New or unusually loud noises are a strong sign something is wrong. Buzzing can indicate an electrical issue such as a failing capacitor, contactor problems, or loose wiring. Rattling may be debris in the outdoor unit, loose panels, or a failing fan blade. Grinding can point to motor bearing problems or a mechanical failure that should be addressed quickly.
If the noise is severe, it is safest to turn the system off and call for diagnosis. Catching the issue early can prevent a small repair from becoming a major component failure.
Water around the indoor unit often means the condensate drain line is clogged, the drain pan is damaged, or the system is producing excess water because a frozen coil is thawing. In Charlotte humidity, condensate can build up fast, and even a partial blockage can cause overflow.
Turn the system off if water is actively dripping near electrical components, and call for service. We can clear the drain line, inspect the pan and safety switch, and confirm the unit is draining properly to help prevent water damage and mold concerns.
The right choice depends on system age, repair history, efficiency, and the type of failure. If your AC is older, needs frequent repairs, or uses R 22 refrigerant, replacement may be the smarter long term investment. If the system is newer and the problem is a common repair such as a capacitor, contactor, or minor airflow issue, repair may be the most cost effective route.
We will inspect your system and explain the condition of key components, expected repair outcomes, and practical replacement options so you can make a confident decision based on comfort, budget, and long term value.
Yes. We repair and maintain ductless mini splits, including single zone and multi zone systems. Common ductless issues include drainage problems, dirty filters and coils, sensor errors, refrigerant leaks, and airflow restrictions. Many mini split problems can be resolved quickly once the system is properly diagnosed.
If one indoor head is not cooling but others are, that can point to a control issue, refrigerant distribution problem, or a maintenance need specific to that zone. We can evaluate the full system and recommend the best path to restore consistent comfort.
The best protection is routine maintenance and simple habit changes. Replace your air filter regularly, keep the outdoor unit clear of leaves and shrubs, and make sure supply and return vents are open. During extreme heat, avoid drastic thermostat changes and use ceiling fans to help air circulate.
Scheduling professional maintenance before peak summer helps us catch issues like weak capacitors, dirty coils, low airflow, or drainage problems that often cause breakdowns during the hottest weeks. It also helps your system run more efficiently and maintain better humidity control.
Yes. High humidity can make a home feel sticky and warmer even when the thermostat reads a lower temperature. If your AC is oversized, short cycles, or has airflow or refrigerant issues, it may cool the air without removing enough moisture. That can lead to clammy rooms, musty odors, and uneven comfort.
We can check system sizing, airflow, and performance to make sure your AC is removing humidity effectively. If needed, we can also recommend solutions like airflow improvements or whole home dehumidification to improve comfort in Charlotte summers.
