Why Is My AC Not Working Properly?

If your air conditioning system isn’t cooling your home properly, the cause could be anything from dirty condenser coils to a broken compressor. Our HVAC technicians at J Hood Services have the expertise to diagnose and repair air conditioning issues quickly and efficiently.

The following are some of the most frequent culprits that could prevent your air conditioning unit from doing its job or cause damage to your home:

Clogged Drain

Your AC unit produces condensation that drips into a pan and flows to a drain, preventing water buildup inside the system. If the drain line becomes clogged by debris, the drip pan will eventually overflow and cause a leak inside your house.

Electrical Issues

Electrical problems, such as a malfunctioning thermostat or faulty wiring, could cause your AC system to trip the circuit breaker and turn off unexpectedly. An experienced AC technician can assess and fix the wiring or recalibrate the thermostat to get your cooling system working again.

Faulty Fans

If your central air conditioner isn’t circulating the air in your home, there might be a problem with the fans. A worn-out fan belt or broken fan motor are issues that lead to inoperable air conditioner fans that might need replacing.

Our expert air conditioner repair services, followed up with regular maintenance by our professional HVAC technicians, will ensure your air conditioning unit stays in tip-top shape.

Poor Air Circulation

Besides broken fans, insufficient airflow can be due to blocked vents, clogged air filters, or an air conditioner unit that’s too small for the size of your home. With these problems, you might notice that only some rooms get cool while others stay hot and humid.

Refrigerant Leak

If you hear an unusual hissing sound coming from your air conditioner system, it could be a sign of leaking refrigerant. Refrigerant is the fluid in your air conditioner that absorbs heat and helps cool down your interior. When it leaks, your system could overheat and become extremely inefficient.

Frozen Evaporator Coils

When coolant levels are low or the air conditioning is running too often, it can cause the evaporator coil to freeze. A frozen evaporator coil can’t adequately cool the warm air passing through your air conditioner.

Defective Parts

As your AC gets older, the components inside, such as the compressor or fans, can start to wear down and reduce the efficiency of your air conditioner. Our technicians can provide air conditioner repair services to fix or replace the parts, but, sometimes, the most cost-effective solution is a total AC replacement.

One of the most common yet overlooked issues leading to air conditioner problems is a dirty filter. This simple component plays a huge role in your AC unit's operational efficiency, and neglecting it can lead to a myriad of difficulties that can hinder your comfort and inflate your cooling costs.

Emergency AC Repair Near Me: What You Need to Know

The air filter's primary function is to protect your AC system's interior components from dirt, dust, and other airborne particles. As the AC operates, it draws in air from the room, which passes through the filter before it enters the cooling system. If this filter becomes saturated with dirt or dust, it restricts airflow into the AC unit and causes several problems.

Exploring AC Repair Services In Leesburg, VA

Knowing what symptoms to look for can help you identify when it’s time to replace or clean your air conditioner’s filter. Here are some signs that you might be dealing with a dirty filter:

  • Reduced Cooling Efficiency: One of the first things you'll notice is that your AC doesn't cool as effectively as it used to. The lowered airflow forces the unit to work harder than necessary, reducing its cooling capacity.

  • Increased Energy Consumption: If your energy bills are climbing despite no apparent change in usage patterns, a dirty air filter could be responsible. Restricted airflow means your AC has to work harder and longer to maintain desired temperatures.

  • Frequent Cycling: A dirty filter will cause an air conditioner to cycle on and off more frequently than normal — an issue known as short cycling — leading to wear and tear.

  • Frozen Evaporator Coil: With low airflow, less heat is absorbed by the evaporator coil which can cause it to freeze over – leading potentially serious damage.

Regular AC Service is Key in Leesburg, VA

Regular maintenance can prevent most issues related with dirty filters:

  • Routine Filter Change: Make it a habit to change your filter every 1-3 months, depending on the type of filter you have and whether you have pets or people with allergies in your home.

Scheduled AC Maintenance: Professionals recommend having your AC serviced at least once a year. This maintenance check typically includes filter changes, along with cleaning and inspections to ensure everything is running smoothly.

Air Conditioning Service in Leesburg, VA: Ensuring Correct Filter Installation

Incorrectly installing a new filter can cause the same problems as a dirty one. Always ensure the filter is the correct size for your unit. The filter's packaging should have an arrow indicating the direction of airflow – this should point towards the AC unit.

A dirty air conditioner filter can cause several issues that compromise your comfort and cost you extra money. Recognizing the symptoms and understanding the importance of regular maintenance can help keep these problems at bay.


Your air conditioning unit can be a lifesaver during the hot summer months. However, if your AC isn't cooling your home to your satisfaction, the culprit could be incorrect thermostat settings. Thermostats are the control center of your air conditioning system, determining when and how much cool air is dispersed throughout your home. Misconfigurations or malfunctions in this component can cause significant inconveniences. Here's a detailed guide to understanding and addressing air conditioner problems stemming from incorrect thermostat settings:

  • Inadequate cooling: If certain parts of your property are not getting cool enough or if the AC unit seems to run constantly without reaching the desired temperature, incorrect thermostat settings could be to blame.

  • Erratic operation: If your AC unit frequently turns on and off or runs at odd times, it could be due to wrong scheduling settings on programmable thermostats.

  • No response: If you adjust the thermostat but see no response from the AC unit, there may be communication issues between these two components.

Air Conditioning Repair Contractor in Leesburg, VA: Solving Incorrect Thermostat Settings

To determine whether incorrect thermostat settings are causing your AC problems, consider these steps:

  1. Verify that the thermostat is set to "cool" mode.

  2. Check that temperature setting is lower than actual room temperature.

  3. Ensure that scheduling settings align with your current needs if you use a programmable thermostat.

  4. If possible, check for display errors or malfunctioning buttons on digital thermostats.

  5. Confirm that there is power supply to the thermostat (batteries aren’t dead or circuit breaker isn’t tripped).

Air Conditioner Contractors in Leesburg, VA: Your Solution to Thermostat-Related Problems

Once you've identified that incorrect thermostat settings are indeed causing AC troubles, here’s what you can do:

  • Reconfigure Settings: Configure it according to your cooling needs. If you have a programmable thermostat, make sure to program it according to your daily routine.

  • Replace Batteries: Dead or weak batteries can often lead to inconsistent performance. Simply replacing the batteries could solve the problem.

  • Reset Thermostat: If you suspect the thermostat is not communicating effectively with your AC unit, try resetting it following manufacturer instructions.

  • Check Wiring: Loose or disconnected wires can disrupt thermostat operation. Please consult with a professional if you are unsure about handling electrical parts.

  • Professional Help: If these steps do not resolve your issue, consider getting help from a licensed technician. They can diagnose and repair any advanced issues related to your thermostat or AC unit.

Remember, maintaining optimal performance of your air conditioning system isn't just about comfort—it's also about energy efficiency and longevity of the system. So, regular checks on crucial components like the thermostat are always recommended for a smooth and satisfying cooling experience.


One of the vital components of an air conditioning system is the circuit breaker. A circuit breaker, primarily, protects your air conditioner and its electrical circuits from potential overload. If there are any issues with your AC's circuit breakers, it can result in problems such as non-functioning of the AC unit or intermittent cooling.

Understanding these issues is essential for proper maintenance and prolonged functionality of your air conditioning unit. Here are some common problems related to air conditioner circuit breakers:

Frequent Tripping

One of the most typical issues you might encounter with your air conditioner's circuit breaker is frequent tripping. When a breaker trips, it essentially means that it has shut off the electrical flow to protect the circuit from potential damage due to an overload or short circuit.

Causes for frequent tripping can range from a simple temporary overload in the system to more severe problems such as a short within the AC unit or even a malfunctioning breaker itself.

Failure to Reset

Sometimes after a trip, you might find that your air conditioner's circuit breaker refuses to reset. This could be caused by a persistent short circuit in the system or an issue with the breaker itself.

Burnt Out Breaker

Circuit breakers are designed to withstand heavy electrical loads over extended periods. However, like any other component, they have their limit and can eventually burn out. A burnt out or damaged breaker will typically fail to function correctly leading to irregularities in AC performance.

If you notice any of these issues persistently occurring with your air conditioner's circuit breakers, here are some recommended steps:

  • Identify and Rectify Overloads: Check if there are any additional devices on the same line that could be causing an overload resulting in regular trips.

  • Inspect for Short Circuits: Look out for sings such as burnt smell or sparking around the AC unit which could indicate presence of a short.

  • Check Wiring and Connections: Ensure all wires and connections related to your AC unit are intact and not damaged.

  • Replace Damaged Breaker: If you suspect that the issue lies with the breaker itself, consider having it replaced by a professional.

However, it should be noted that dealing with electrical components like circuit breakers involves risks if handled improperly. Therefore, when in doubt consult with a professional HVAC technician who can safely diagnose and rectify these issues while ensuring safety standards are met.

By understanding these common problems associated with air conditioner circuit breakers, it becomes easier for homeowners to identify potential causes behind their faulty AC units and seek appropriate remedies promptly.


Maintaining an optimal temperature inside your house during the scorching summer months heavily depends on the proper functioning of your air conditioner (AC). However, sometimes, despite ensuring routine checks and performing necessary actions, your AC might not provide efficient cooling. One of the common causes behind such an issue can be a dirty outdoor unit of your AC. Therefore, understanding how to detect and resolve such problems is crucial for seamless operation.

Detecting Issues with Outdoor Units

Detecting an issue with your outdoor unit mainly involves observation and understanding the functioning of various components. Here are a few indicators that might signal a problem:

  • Decreased Cooling Efficiency: One clear sign that your outdoor unit needs attention is if you notice decreased cooling efficiency. If your AC isn't cooling as efficiently as it did before, it might be due to a dirty outdoor unit.

  • AC Overheating: If you notice that the system is overheating or there's warm air coming out from the AC vents, it could indicate that the outdoor unit isn't able to dissipate heat properly due to dirt accumulation.

  • Unusual Noise from the Unit: A well-functioning outdoor unit operates quietly. If you start hearing unusual noises from the system, there may be debris lodged in it.

  • Visual Inspection: Lastly, visually inspect your outdoor unit for any dirt or debris buildup periodically.

Steps for Resolving Issues with Dirty Outdoor Units

A dirty outdoor unit can cause significant cooling issues with your AC system. Here are some steps you can follow:

Step 1: Turn off the Power Before starting any maintenance work on your air conditioning system, make sure to turn off all power supply to avoid accidents.

Step 2: Clean Around The Unit Remove any leaves, grass clippings or other debris around the condenser unit on top and sides. This will allow better airflow around it.

Step 3: Clean The Condenser Coils The condenser coils need proper cleaning as they directly affect heat exchange process. Use a coil cleaner available at HVAC supply stores or local home improvement stores. Follow instructions given on cleaner for best results.

Step 4: Check/Clean The Fan Inspect fan blades for any damage and clean them using a soft cloth or brush with water and mild detergent.

Step 5: Inspect Condensate Drain Line Ensure that condensate drain line is clean and free from blockages so that moisture can easily exit.

Though these steps can help in resolving air conditioning problems linked to a dirty outdoor unit, regular professional maintenance is recommended for optimal performance of your AC system throughout its lifespan. It not only ensures efficient cooling but also helps in identifying potential problems early before they turn into major issues requiring extensive repairs or replacement.
