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.

Air conditioning systems are ubiquitous in homes and offices, providing indispensable comfort during hot summer months. Despite their widespread use, several misconceptions surround air conditioning systems, leading to inefficient use or unnecessary wear and tear. Here we aim to debunk some of these common beliefs.

Myth 1: Lowering the thermostat cools your home fasterContrary to popular belief, setting your thermostat at a lower temperature does not cool your home more quickly. AC units work at a fixed rate, so setting the temperature too low may result in unnecessary energy consumption without speeding up the cooling process.

Myth 2: Fans can replace ACs in coolingWhile fans can make a room feel cooler by circulating air, they do not decrease the actual temperature of the room like an air conditioner does. Fans are best used in conjunction with an AC system to distribute cooled air evenly throughout a space.

Myth 3: You only need to change filters once a yearThe frequency with which you should change your air filter varies depending on factors like usage and indoor air quality. In general, it's recommended that you replace your filter every 60-90 days for optimal performance.

Myth 4: It’s more economical to leave the AC running all daySome believe that turning off the AC when you leave home only forces it to work harder when it's turned back on. However, modern AC systems are designed to cool spaces efficiently and rapidly, making this practice wasteful.

Myth 5: Closing vents in unused rooms increases efficiencyContrary to this belief, closing vents can actually decrease system efficiency by increasing duct pressure and causing leaks.

Myth 6: All Air Conditioners Humidify Your HomeWhile some models do have humidifying functions, not all air conditioners will increase the humidity in your home. It's a common misconception that ACs work like dehumidifiers. This is not the case; they cool your home by removing heat, not moisture.

Myth 7: AC maintenance isn’t necessary unless there’s a problem

By understanding these truths about air conditioning, you can optimize your AC system's performance, increase its lifespan, and potentially reduce your energy bills. Always remember to employ best practices in using your cooling system for greater comfort and efficiency.

The role of an air conditioner in maintaining a comfortable living environment is often overlooked. Contrary to what many people believe, air conditioning is more than just cooling the air. It involves improving the overall air quality, circulation, and comfort within your home. This article will delve into the significant impact of air conditioners on home comfort.

Enhancing Your Air Conditioner Services in Oakton, VA

The first aspect of home comfort that an AC unit impacts is indoor air quality. Modern air conditioners have advanced filtration systems that work to filter out dust, pollen, and other potentially harmful particles from the air. With continuous cycling of air through these filters, homeowners can enjoy cleaner, healthier indoor air.

  • Air Filtration: Filters in AC units trap dust particles and allergens.

  • Humidity Control: AC units reduce humidity levels indoors, creating a more comfortable environment.

  • Ventilation: Regular cycling of indoor and outdoor air helps maintain fresh and clean airflow.

Air circulation is another crucial factor that contributes to home comfort. Good circulation promotes even distribution of temperature across all rooms in your home, eliminating hot or cold spots that can make certain areas uncomfortable.

  • It helps prevent mold growth by reducing moisture accumulation in certain areas.

  • It aids in removing pollutants from your home by cycling them out.

Air Conditioner Contractors in Oakton, VA: Specialists in Regulation of Humidity Levels

High humidity levels inside a house can cause discomfort irrespective of the temperature setting on the thermostat. An efficient air conditioner extracts excess moisture from indoor air, helping maintain an ideal humidity level in your house - anywhere between 30% to 50%.

Energy Efficiency

A well-maintained and efficient AC unit doesn't have to work as hard to cool down your house or maintain a comfortable temperature. This leads not only to lower energy bills but also a consistent level of comfort throughout the day.

Case study: A home with an efficient AC unit vs. a home without one.

Understanding the significant role air conditioning plays in maintaining indoor comfort, it becomes clear why regular servicing and maintenance of your AC unit is so crucial. It’s not just about lowering your energy bills—it's also about ensuring your home is a comfortable place to live.

Remember, an efficiently running air conditioning unit can make all the difference in improving the comfort and quality of life in your home. 


Many people believe in the myth that a bigger air conditioner will provide superior results. The misconception is based on the assumption that larger capacity or higher BTU (British Thermal Units) air conditioners will cool a room more effectively, or faster. However, this isn't necessarily the case.

Firstly, an excessively large AC unit can lead to short cycling. This is where the cooling cycle is shorter than it should be, causing your appliance to stop and start frequently. Not only can this lead to temperature inconsistencies and discomfort, but it can also wear down your AC quicker and increase your energy bills.

The general considerations for selecting the right size of an air conditioning system include the following:

  • Size of the space: A larger space may require a bigger unit to efficiently cool down every corner.

  • Heat-generating appliances: If you have many heat-producing appliances in your space, you might need a larger unit.

  • The number of occupants: More people generate more heat which might require a bigger unit.

  • Local climate: Hotter climates generally require more powerful units.

Secondly, while it may seem that a bigger AC will cool down a room faster, it could lead to another problem called 'clamminess'. This is because one of an air conditioner's jobs is to reduce humidity. However, if your AC cools down the room too quickly and switches off before it has had enough time to dehumidify properly - you could be left with cold yet still humid air.

It's also important to consider energy efficiency when choosing an air conditioner. Larger units tend to consume more power even if they run for shorter times due to their overcapacity. Hence they might not be as energy-efficient as smaller ones.

So how do you choose the right size of an AC unit?

The best way is through a calculation called a 'load calculation'. This is where you determine the amount of cooling your home needs based on its size, insulation, and other factors. Experts or HVAC contractors can do this for you.

In summary, while it may seem logical to think that a bigger air conditioner will provide superior results - it isn't always the case. An excessively large unit can lead to short cycling, inconsistencies in temperature, increased energy bills and could still leave your room feeling clammy due to ineffective dehumidification.

When choosing an air conditioner, remember to consider your space size, number of occupants, heat-generating appliances and local climate. Always aim for energy efficiency and consider having a load calculation done by an expert to ensure you're getting the right size AC for your needs.

The efficiency of your air conditioning unit is a critical factor in maintaining a comfortable temperature in your home and managing energy costs. A key element influencing this efficiency is the thermostat's setting. Understanding how varying temperatures on your thermostat impacts the cooling efficiency can lead to more effective usage and overall improved home comfort.

The Role of Thermostats

Thermostats, essentially are the control units for your heating, ventilation, and air conditioning (HVAC) systems. They measure your home's current temperature and compare it against the set point you indicate. If there's a difference, they signal the HVAC system to work until the set temperature is achieved.

The Ideal Thermostat Temperature

For optimal cooling efficiency, most experts recommend setting your thermostat at 78 degrees Fahrenheit (25 degrees Celsius) during warm months when you're at home. This is considered a comfortable indoor temperature for most people and will help keep energy costs down.

Effects of Lowering Thermostat Temperature

Lowering the thermostat temperature won't necessarily cool down your house faster. Since AC units work at a constant pace until they reach their set temperature, setting an extremely low temperature will only make your unit work longer, not harder or faster.

Also, constantly adjusting temperatures or setting them too low can lead to:

  • Higher energy bills: More energy is consumed as the AC unit works harder to maintain a much cooler temperature.

  • Increased wear and tear: Continual operation puts more strain on the AC’s components.

  • Reduced lifespan: Overworking can shorten the system's lifespan over time.

Strategies for Enhancing Cooling Efficiency

Here are some strategies to help improve cooling efficiency:

  • Use programmable thermostats: These allow you to schedule different temperatures throughout the day based on when you'll be home or away.

  • Regular maintenance: Regular servicing ensures that your AC runs efficiently by correcting minor issues before they escalate.

  • Mindful usage: Avoid unnecessary usage during cooler times of day or when no one is at home.

In sum, understanding how thermostat settings influence cooling efficiency can enhance comfort levels while also reducing energy consumption and prolonging system life. So consider these points before making drastic adjustments to that dial.
