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 Fair Oaks, VA and How It Enhances Indoor Air Quality

Air conditioning, often referred to as AC, is a system that cools, ventilates, and dehumidifies the air in indoor spaces. This leads to a comfortable and healthy living environment. It's not just about temperature control; one of the key benefits is enhancing indoor air quality (IAQ).

Understanding the Importance of Air Conditioner Repair in Fair Oaks, VA

Indoor air quality is an essential aspect of our health. The Environmental Protection Agency (EPA) states that indoor air pollutants are among the top five environmental risks to public health. Poor IAQ can lead to short-term discomfort like headaches, fatigue, and allergies. Long-term effects can be more severe like respiratory diseases or even cancer.

Air Conditioning Repair in Fair Oaks, VA: Your Ultimate Guide

Air conditioning systems enhance indoor air quality in several ways:

  • Removing Heat: AC units extract heat from the room’s air and release it outside, reducing the room temperature.

  • Dehumidifying: Humidity creates an environment for moulds and mites to thrive. ACs remove excess moisture from the air, reducing humidity levels which in turn mitigates such growth.

  • Ventilation: A well-designed AC system can provide adequate ventilation, continually cycling in fresh outdoor air and pushing out stale indoor air.

  • Filtering Pollutants: Many modern AC units have filters that can trap dust particles, pollen, pet dander, smoke particles etc., purifying your indoor air.

The effectiveness of an AC unit in improving IAQ depends on its maintenance. Dirty filters or ductwork can reduce efficiency and even become sources of pollution themselves.

Finding Reliable "Emergency AC Repair Near Me": A Comprehensive Guide

Here are a few tips for maintaining your air conditioning system:

  1. Regularly Clean/Replace Filters: Check manufacturer guidelines for how frequently you should do this.

  2. Clean Ducts: Have your ductwork professionally inspected and cleaned every 3-5 years.

  3. Ensure Proper Ventilation: Make sure vents aren’t blocked by furniture or other objects.

  4. Regular Servicing: Hire a professional for regular servicing.

By understanding how an AC works to enhance indoor air quality, you can take proactive steps to ensure optimal functioning of your unit and create a safer and healthier environment within your home or office space.

The Indispensable Role of AC Repair Services in Fair Oaks, VA in Improving Indoor Air Quality

Air conditioning systems play an instrumental role in enhancing public health by significantly improving indoor air quality. This is achieved through various processes that include ventilation, filtration, humidity control, and temperature regulation.


Ventilation stands out as one of the crucial roles played by air conditioning systems towards boosting indoor air quality. It entails the exchange of indoor air with fresh outdoor air, thereby reducing the concentration of pollutants within an enclosed environment.

  • The system expels stale indoor air filled with pollutants.

  • Subsequently, it draws in fresh outdoor air to replace the expelled one.

  • This process reduces the concentration of contaminants and enhances the overall quality of indoor air.


Filtration is another critical function fulfilled by the AC system. It fundamentally involves removing particles and other pollutants from the circulated air.

  • The AC system's filter traps dust, allergens, particulate matter among other contaminants from circulating air.

  • The filtered clean air then gets redistributed within a space.

Humidity Control

Air conditioning systems also manage humidity levels within an indoor environment which directly impacts on human health and comfort.

High humidity:

  • Encourages mold growth

  • Increases dust mite populations

  • Can cause damage to buildings

Low humidity:

  • Can cause dry skin and respiratory problems

  • May lead to static electricity issues

  • Can damage wooden furniture and musical instruments

An efficient AC system maintains a balanced humidity level minimizing these potential issues.

Temperature Regulation

Lastly, temperature regulation is an integral aspect of public health addressed by AC units. Extreme temperatures can trigger numerous health concerns such as heat stroke or hypothermia.

Benefits of temperature regulation include:

  1. Prevention of overheating which can lead to heat stroke or dehydration.

  2. Maintenance of a comfortable living or working environment.

  3. Minimization of the risk of cold-related ailments during chilling periods.

Indeed, the role of air conditioning systems in promoting public health by improving indoor air quality is indispensable. The systems provide a viable solution to managing environmental conditions within enclosed spaces, making them habitable and healthy for human occupancy. By doing so, they significantly reduce the risk of health concerns associated with poor indoor air quality. Therefore, proper use and maintenance of these systems should be a priority for everyone aiming to live or work in a clean and safe environment.


Air conditioning units have become a staple in modern living environments. While they are primarily recognized for their role in climate control, reducing heat and maintaining comfortable temperatures, their potential to improve indoor air quality is often overlooked.

Air conditioning units can significantly improve indoor air quality by circulating and filtering the air. This process removes pollutants like dust, allergens, and other harmful particles that can adversely affect the health and comfort of inhabitants. Let’s delve into how exactly this happens.

Air filtration

The primary way air conditioning units improve indoor air quality is by filtering the air that circulates within a room or building. These filters trap airborne particles such as dust, pollen, pet dander, and mold spores, preventing them from being recirculated. Over time, this leads to a decrease in airborne pollutants and an improvement in indoor air quality.

Humidity control

Air conditioners also play a vital role in controlling humidity levels within an environment. High humidity levels can facilitate the growth of mold and mildew which can compromise indoor air quality. By removing excess moisture from the air during the cooling process, it ensures that humidity levels remain low enough to prevent this from occurring.


In addition to filtering particles and controlling humidity, most modern air conditioning systems also have ventilation capabilities which allow fresh outdoor air to replace stale indoor air thereby improving overall indoor air quality.

However, it's important to note that not all AC systems perform these functions with equal effectiveness. The efficacy of an AC unit in improving indoor air quality depends on factors such as its filtration capabilities (determined by its Minimum Efficiency Reporting Value or MERV rating), its maintenance schedule (including regular filter changes), and how well it's been sized for the space it's cooling.

It is also important to pair your AC use with other good habits for optimum results:

  • Regularly clean and vacuum your home to remove sources of air pollution.

  • Ensure adequate ventilation, especially if you are using products that can emit harmful pollutants.

  • Use air purifiers and other air cleaning devices in conjunction with your AC system.

In sum, while air conditioning can indeed play a significant role in improving indoor air quality, it’s not a standalone solution. A comprehensive approach that combines regular maintenance of the AC unit, good housekeeping practices, and other air purification methods is the most effective way to ensure clean, healthy indoor air.


World Climate Day is a global observance dedicated to raising awareness about climate change and promoting actions to protect our environment. Among the various factors that contribute to this cause, the role of air conditioning systems might seem insignificant at first glance. However, upon deeper examination, it becomes clear that these everyday appliances have a significant impact on our environment.

Air conditioning systems have a dual relationship with environmental action. On one side, they are necessary for maintaining comfortable living and working conditions, particularly in hotter climates. On the other side, they consume a significant amount of energy and contribute to greenhouse gas emissions if not properly managed or outdated models are used.

AC Service in Fair Oaks, VA: Reducing Energy Consumption

Air conditioning systems account for approximately 10% of global electricity consumption. This figure can rise dramatically during peak summers when the demand for cooling increases. Given the dependency on fossil fuels for electricity generation in many parts of the world, this results in substantial carbon emissions.

To mitigate this impact:

  • Switching to high-efficiency air conditioning units can significantly reduce energy consumption.

  • Regular maintenance can keep your system running efficiently.

  • Smart thermostats can help manage cooling times effectively.

Air Conditioning Service In Fair Oaks, VA

Many air conditioners use refrigerants that are potent greenhouse gases when leaked into the atmosphere. Hydrofluorocarbons (HFCs), commonly used in older air conditioners, have thousands of times more warming potential than carbon dioxide.

To combat this issue:

  • Choose air conditioners that use environmentally friendly refrigerants.

  • Properly recycle old air conditioning units to prevent HFC leakage.

Air Conditioner Services In Fair Oaks, VA

Air conditioners expel warm air outside during their operation, contributing to the urban heat island effect — an increase in temperature in densely populated areas compared to surrounding rural areas. This creates a vicious cycle as increasing temperatures lead to higher demand for cooling.

Solutions include:

  • Planting trees or installing green roofs can help cool buildings naturally.

  • Using building materials that reflect, rather than absorb, sunlight.
