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.

Understanding AC Repair in South Riding, VA and its Role in Influencing Indoor Air Quality

The air conditioning (AC) system plays a significant role in maintaining indoor air quality. While it is common knowledge that an AC system cools the air inside a building or home, many are unaware that it also improves air quality by reducing allergens and contaminants from the air.

AC systems work by taking in warm indoor air, which is then passed over cooling coils to reduce its temperature. During this process, these coils condense moisture from the air, effectively reducing humidity. This results in a controlled and comfortable environment for occupants.

However, beyond cooling and dehumidification, AC units also filter the incoming air. This is an essential function as it eliminates particles and contaminants that can cause harm to our health.

Exploring AC Maintenance in South Riding, VA

The filtration system of an AC unit is vital for improving indoor air quality. As mentioned earlier, when warm indoor air passes over cooling coils, not only is it cooled down but also filtered.
Air filters vary depending on their Minimum Efficiency Reporting Value (MERV). MERV ratings define the size of particles that filters can trap and ranges from 1 to 20. Higher MERV ratings indicate greater efficiency at trapping smaller particles. Here are some common types of filters:
Fiberglass/synthetic filters: These are typically rated between 1-4 MERV.
Pleated filters: These have MERV ratings between 5-8.
Electrostatic filters: They usually have between 2-10 MERV rating.
Choosing the right filter for your AC unit depends on your specific needs and circumstances.

Air Conditioner Repair In South Riding, VA: Ensuring Your AC System Helps in Mold Prevention

Mold growth thrives under high moisture levels; hence reduced humidity helps prevent mold growth. By condensing moisture from incoming warm indoor air during its cooling process, AC units effectively reduce dampness within a building or house, thereby helping prevent mold growth.

To ensure the effectiveness of your AC unit in mold prevention, routine maintenance is crucial. This includes regular cleaning and changing of AC filters to inhibit any potential buildup of dust, which can trap moisture and become a breeding ground for mold.

Managing Your Air Conditioning Repair in South Riding, VA

Air conditioning units are instrumental in managing indoor allergen levels. Their filtering system helps to reduce common airborne allergens such as dust mites, pet dander, and pollen.

The filtration system present in the AC units traps these allergens and prevents them from circulating back into the indoor air. However, this also means that over time, these filters may become clogged with allergens and would require regular replacement or cleaning to maintain the air quality.

Our indoor environment can sometimes contain higher pollution levels than the outdoors due to limited ventilation. Indoor pollution sources such as household cleaning products, building materials, and even cooking can contribute to poor indoor air quality.

An efficiently functioning AC unit does not just cool the air but also purifies it by trapping these pollutants within its filters. This contributes significantly to reducing indoor pollution levels thereby improving overall indoor air quality. Therefore, regular maintenance including timely filter replacements is key for an AC unit to perform this function effectively.

The filtration system in your air conditioner plays an integral role in maintaining a healthy and comfortable indoor environment. This is because it removes various pollutants, allergens, and other harmful particles from the air before cooling it and circulating it back into your living space. Let's take a closer look at this component of your AC unit to understand how it works.

Basic Structure of an AC Filtration System

An AC filtration system primarily consists of the following parts:

  • Filter Media: This is typically made from synthetic materials designed to trap various particles. The exact composition may vary depending on the type and model of the AC unit.

  • Frame: The frame holds the filter media in place within the unit. It is usually designed to withstand temperature changes and resist moisture, ensuring proper function under various conditions.

  • Sealant: This substance is used to secure the filter media within the frame, preventing any unfiltered air from bypassing the filter.

Working Mechanism

As air passes through your AC unit, it first goes through the filtration system. Here, tiny particles get trapped within the fibrous material of the filter media while cleaner air passes through. With time, these trapped particles accumulate on the surface of filters creating a barrier that further aids filtration by blocking smaller particles that might have initially passed through.

However, this accumulation can also decrease airflow over time if not properly maintained. This can negatively impact both your comfort and energy efficiency.

Importance of Regular Maintenance

Just as important as understanding how your AC's filtration system works is knowing how to maintain it. Regular maintenance helps ensure optimal function and extends its lifespan:

  • Regular Filter Changes: Depending on usage conditions and filter type, you should change or clean your filters every 1-3 months during cooling season. Dirty filters can reduce airflow and may cause other issues such as icing on refrigerant lines.

  • Inspection for Damage: During each filter change, inspect for signs of damage such as bent frames or torn media which could allow unfiltered air into your indoor environment.

By understanding more about how your AC's filtration system works, you're better equipped to maintain it for optimal indoor air quality. Besides reducing pollutants, a well-maintained filtration system also improves overall HVAC performance by reducing strain on other components like fans and coils.

Optimizing Your AC Service in South Riding, VA for Mold Prevention

A well-functioning air conditioning (AC) system plays a crucial role in preventing mold growth. This is due to the AC's ability to control the humidity level within your home or office, creating an unsuitable environment for mold to thrive.

Mold spores are present almost everywhere, both indoors and outdoors, and they propagate swiftly in high humidity conditions. It becomes a problem when it starts growing inside homes as it can lead to health issues like allergies and respiratory problems.

Role of AC in Controlling Moisture Levels

Your air conditioner does more than just cool the air. It's a crucial factor in controlling indoor humidity levels. One of the primary functions of an AC system is to remove excess moisture from the indoor environment:

  • The process begins when warm, humid air from your home is pulled into the air conditioner.

  • This air passes over the system’s evaporator coil, which is cooler than the incoming air.

  • When this happens, condensation occurs on the coil’s surface – much like how condensation forms on the outside of a cold glass on a hot day.

  • This condensation is collected in a drain pan and then removed from your home via the condensate drain line.

  • The result? Cooler, less humid air circulated back into your home.

By controlling indoor humidity levels, your AC system creates an environment that’s inhospitable for mold growth.

Effective Maintenance for Mold Prevention

Effective maintenance of your AC unit also aids in preventing mold growth:

  1. Regular filter changes: Over time, dust and dirt clog up filters decreasing their efficiency and potentially leading to higher humidity levels. Regular filter changes ensure that moisture is effectively removed from your indoor environment.

  2. Annual HVAC inspections: An annual check-up will address any potential problems with your cooling system before they become major issues.

  3. Proper sizing: The size of your AC unit should be suitable for space it needs to cool; inadequately sized units may not effectively control moisture levels.

  4. Properly sealed ducts: Leaky ducts can pull in moisture from unconditioned spaces leading to higher indoor humidity.

Importance of Temperature Control

Temperature setting plays a key role as well - if you set your thermostat too high, or turn off your AC when you leave home during summer months, it might result in escalated humidity levels that may encourage mold growth.

Keep these things in mind so you can create an unfavorable environment for mold growth by maintaining ideal temperature and relative humidity levels with proper use and maintenance of your cooling system.

Remember that while controlling moisture with an efficient AC system is important, some situations may require additional solutions such as dehumidifiers or professional mold remediation services if an issue already exists.

By understanding how our AC systems help prevent mold growth we can ensure they operate efficiently while also providing us safer, healthier homes and workspaces.


Managing allergens in your home can be quite challenging, especially during seasons like spring and fall when pollen counts can be particularly high. One of the most effective ways to keep allergens at bay is by implementing proper air conditioning practices.

Air conditioning units do more than just cool your home. They play a significant role in filtering out allergens and maintaining healthy indoor air quality. If not properly maintained, however, they can also contribute to an increase in allergen concentration indoors.

Air Conditioning Service in South Riding, VA: How Your AC Unit Filters Allergens

An AC unit consists of a filter that traps and removes airborne particles from the indoor air. This includes various types of allergens such as dust mites, mold spores, pollen grains, and pet dander. Here's how it works:

  1. As the AC operates, it draws in warm air from your home.

  2. This air passes through the AC filter where most airborne particles are trapped.

  3. The filtered air is then cooled down and recirculated back into your space.

This process ensures that you are breathing cleaner, less allergenic air.

The Importance of Regular AC Filter Changes: Air Conditioner Services In South Riding, VA

The effectiveness of your AC unit in managing allergens greatly depends on the condition of its filter. Over time, filters will accumulate dust and other particles which reduces their efficiency.

  • Clogged filters: A clogged filter not only reduces cooling efficiency but also increases energy consumption as your unit will need to work harder to draw in and cool down air.

  • Allergen build-up: More importantly for allergy sufferers, a clogged filter is no longer able to trap additional allergens effectively which can lead to an increase in indoor allergy symptoms.

  • Mold growth: In extreme cases where filters are left unchanged for extended periods, they may become damp and start developing mold which can exacerbate allergy symptoms even further.

The best practice is to replace your AC filters every 60-90 days, or more frequently if you have pets or are particularly sensitive to allergens.

Selecting the Right Air Conditioning Repair Contractor in South Riding, VA

The effectiveness of an AC filter in trapping allergens is measured using the Minimum Efficiency Reporting Value (MERV) rating. The higher the MERV rating, the smaller the particles it can filter out.

For homes, it is recommended to use filters with a MERV rating of 7-12 which will capture most household allergens effectively. Filters with higher ratings (13-16) are typically used in hospitals and other healthcare facilities where ultra-clean air is necessary.

Aside from filter changes, regular maintenance of your AC unit also contributes to better allergen management. This includes cleaning the coils and drain pans which can become breeding grounds for mold and bacteria.

By understanding how your air conditioning unit manages allergens and implementing proper maintenance practices, you can significantly improve indoor air quality and make your home a more comfortable place for everyone.


Air conditioning systems play a crucial role in managing indoor pollution levels. They help to maintain a clean, healthy environment within our homes and offices by filtering out pollutants and contaminants from the air. Hence, understanding how ACs contribute to managing indoor pollution is essential for maintaining good air quality inside your living spaces.

Firstly, air conditioners assist in controlling particulate matter present in the interior atmosphere. Particulate matter refers to tiny particles or droplets in the air that are small enough to be breathed into the lungs. Sources of such particles include dust, dirt, smoke and soot from vehicles, factories and wood-burning stoves. Air conditioners contain filters that capture these particles before they circulate back into your house.

To illustrate this further, here's a simple breakdown of how an AC filter works:

  1. The AC pulls in air from your home.

  2. This air passes through a filter where particulates like dust and dirt are captured.

  3. Cleaned air is then recirculated back into your home.

Secondly, they also eliminate harmful Volatile Organic Compounds (VOCs) from indoor environments. VOCs are gases emitted by certain liquids and solids which can have both short- and long-term adverse health effects. Common sources of VOCs include paint, cleaning supplies, pesticides, building materials and furnishings.

Air conditioning systems can help reduce exposure to VOCs by:

  • Ensuring proper ventilation: An effective AC system circulates fresh outdoor air throughout the home, diluting concentrations of indoor pollutants.

  • Controlling humidity: High humidity levels can increase concentrations of VOCs. By managing indoor humidity levels effectively through dehumidification processes, AC systems help minimize this risk.

Lastly, an often-overlooked aspect is how AC units help manage bioaerosol pollution inside our homes or offices. Bioaerosols include bacteria, viruses, fungi, and airborne allergens like pollen. Proper maintenance and regular filter changes in an AC unit can help control these airborne biological pollutants, thus maintaining better indoor air quality.

In summary, the role of an air conditioner extends beyond just cooling a space. It plays a significant role in mitigating indoor pollution levels by trapping particulates, reducing VOC concentrations, and managing bioaerosols. However, it's essential to remember that to reap these benefits fully; it is crucial to ensure regular maintenance and timely replacement of AC filters. Clean filters not only improve the efficiency of your air conditioner but also significantly enhance the indoor air quality by effectively trapping pollutants.

By understanding how your AC manages indoor pollution levels, you can take proactive steps towards maintaining a healthier and cleaner living environment.
