Common HVAC Issues
Faulty Fuse or Breaker
If your system suddenly stops working, check your breaker box first. A tripped breaker or blown fuse can cut power to your HVAC system entirely. If the breaker trips again after resetting, that's a sign of an underlying electrical issue that needs a technician - not another reset.
Clogged Air Filter
A clogged filter restricts airflow and forces your system to work harder to move air through your home. Over time this leads to overheating, reduced cooling capacity, and potential system shutdown. Filters should be checked monthly and replaced regularly - a dirty filter is one of the most preventable causes of AC repair calls.
Thermostat Issues
A faulty or miscalibrated thermostat can cause your system to run longer than needed, driving up energy bills and putting unnecessary wear on components. If your system is short-cycling, running constantly, or not responding to temperature changes, the thermostat is one of the first things to check. Replacement is often straightforward, but the diagnosis matters - sometimes the issue is wiring or placement, not the thermostat itself.
Broken Blower Motor
The blower motor pushes conditioned air through your ductwork and into each room. When it fails, airflow drops or stops entirely - your system may still run but you'll notice little to no air coming from the vents. A failed blower motor requires professional repair and is not a fix to put off, as running the system without proper airflow can cause additional component damage.
Malfunctioning Circuit Board
The control board is the brain of your HVAC system - it manages the signals between the thermostat, blower, and heating or cooling components. When it malfunctions, the system may shut down unexpectedly, behave erratically, or fail to start at all. Circuit board issues require professional diagnosis, as the symptoms often overlap with other electrical faults.
Broken Expansion Valve
The expansion valve controls how much refrigerant flows into the evaporator coil. When it fails, your system may cool unevenly, freeze up, or lose cooling capacity altogether. Left unaddressed, a faulty expansion valve puts added stress on the compressor - one of the most expensive components in the system to replace.
Broken Capacitor
The capacitor gives the compressor and blower motor the electrical charge they need to start. A failing capacitor often shows up as a system that clicks but won't start, shuts off shortly after turning on, or makes a humming sound. It's one of the more common AC repair fixes and, when caught early, one of the more affordable ones.
Freon Leak
A refrigerant leak is often caused by cracks or corrosion in the evaporator coil. When refrigerant levels drop, your air conditioner loses cooling capacity and may run continuously without reaching your set temperature.
Damaged Compressor
The compressor circulates refrigerant through your system and is central to the cooling process. When it fails, the system loses its ability to cool entirely. Compressor failure is one of the more costly AC repairs - in older systems, it often makes more financial sense to evaluate full replacement rather than compressor-only repair.
AC Repair and HVAC Service for Mobile, AL Homeowners

FAQ's
How do I know if my HVAC system needs repair or replacement?
A good rule of thumb: if the repair cost exceeds half the price of a new system and your unit is more than 10-12 years old, replacement is often the smarter investment. That said, many AC repair situations are straightforward fixes - a failed capacitor, a refrigerant charge, or a thermostat swap - that extend system life significantly. Netherland Air Conditioning can give you an honest assessment of your system's condition and help you weigh repair versus replacement based on actual performance and cost.
What are the most common HVAC issues homeowners face?
The most common air conditioner repair calls our team receives involve refrigerant leaks, failed capacitors, dirty or frozen evaporator coils, thermostat issues, and clogged drain lines. In Mobile's climate, coil and drainage problems are especially frequent because of how long systems run during the summer. Most of these issues start small and become expensive when left alone. Catching them early through regular maintenance is the most effective way to avoid a major breakdown.
How often should I schedule HVAC maintenance?
Twice a year is the standard recommendation - once in the spring before cooling season and once in the fall before heating season. In Mobile, AL, where air conditioners run hard from April through October, a spring tune-up is especially important for catching worn components before peak demand hits. Netherland Air Conditioning offers maintenance service for residential systems to help prevent the kind of failures that turn into emergency HVAC repair calls.
Why is my energy bill suddenly higher than usual?
A sharp rise in energy costs without a change in usage patterns usually points to something mechanical. Low refrigerant, a failing capacitor, dirty coils, or duct leaks all force your system to run longer to hit your set temperature - which drives up the bill. Our team can inspect your system, identify the source of the inefficiency, and give you a clear picture of what an HVAC repair would cost compared to continuing to run the system as-is.
What happens if I neglect regular HVAC maintenance?
Skipping maintenance doesn't just mean more repair calls - it shortens the overall lifespan of the system. Dust on coils, restricted airflow from clogged filters, and worn components increase mechanical stress over time, eventually showing up as compressor failure or a cracked heat exchanger - repairs that often cost more than the system is worth. A routine tune-up from Netherland Air Conditioning costs a fraction of what those failures do.
How can I improve my indoor air quality?
Indoor air quality problems often start inside the HVAC system itself - dirty coils, mold in the ductwork, or a filter that hasn't been changed in months. Upgrading to a higher-MERV filter, scheduling a duct inspection, and addressing any moisture issues at the coil can make a measurable difference. Our team also offers UV light purification and humidity control options for homeowners dealing with persistent air quality or allergen concerns in Mobile's humid climate.
Why is my HVAC system making strange noises?
Different noises point to different problems. Banging or rattling usually indicates a loose component - often in the blower assembly. Hissing is commonly a refrigerant leak. Grinding typically points to a failing blower motor bearing. None of these sounds resolve on their own, and most get worse under continued load. If you're hearing something unusual from your system in Mobile, AL, contact Netherland Air Conditioning for a diagnostic before it becomes a more involved HVAC repair.
What is the best thermostat setting for energy efficiency?
The EPA recommends 78°F when you're home and higher when you're away during cooling season. For heating, 68°F while home and lower when away is a reasonable baseline. The bigger efficiency gain usually comes from a programmable or smart thermostat that adjusts automatically - particularly in Mobile, where the shoulder seasons between spring and fall are short and systems switch between modes frequently. Our team can recommend and install smart thermostats compatible with your existing system, which also makes it easier to catch performance drops early before they turn into repair calls.
How long does an HVAC system typically last?
Central air conditioning systems typically last 12-15 years in Mobile, AL - slightly shorter than the national average because of how hard they run during the long cooling season. Heat pumps run year-round and tend to wear faster than straight-cool systems. If your system is approaching 12+ years and you're seeing increasing repair frequency, Netherland Air Conditioning can evaluate whether continued AC repair or a planned replacement makes more financial sense.
Is it worth repairing an older HVAC system?
It depends on the repair type, the system's age, and how it has been maintained. A single repair on a 12-year-old system that has been serviced regularly is often worth doing. A second major repair in the same season on a neglected 14-year-old unit is a different calculation. Our technicians give you the information you need to make that call - repair costs, expected remaining system life, and what a replacement would look like - without pushing you toward a higher ticket if it's not warranted.
