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.

Comprehensive Guide on Choosing the Ideal AC Repair in Chantilly, VA for Your Home


Buying an air conditioning unit involves assessing several factors to ensure that you are investing in the right equipment. These factors include the size of your space, the climate in your area, and the energy efficiency of the unit.


Understanding Air Conditioner Repair in Chantilly, VA

The size of your home or room where you want to install an air conditioning unit has a significant effect on the type of AC you should choose. Undersized units might not cool a room properly during hot days while oversized air conditioners might lead to uneven cooling, energy inefficiency, and increased costs.

To determine the right AC size for your space:

  • First, measure your room's dimensions - length, width, and height.

  • Next, calculate its total volume (length x width x height).

  • Finally, consider other factors such as insulation levels and sun exposure to arrive at the appropriate BTU (British Thermal Units), which measures cooling capacity. As a general rule of thumb, you need roughly 20 BTUs per square foot.

The cooling capacity of an air conditioning unit is measured in terms of tonnage. One ton equals to 12,000 BTUs per hour, which can cool down approximately 450-500 square feet of space.

A standard residential AC unit usually falls between 1 to 5 tons.

  • Calculate your requirement based on square footage and adjust for factors like occupancy, insulation, and sun exposure.

  • Remember that bigger isn’t always better. An oversized air conditioner may not dehumidify properly and could short-cycle, leading to wear and tear.

  • Consult with a professional HVAC technician to help you make an informed decision.

In conclusion, selecting the right air conditioning system requires considering several crucial factors - from size, climate and weather considerations, energy efficiency to capacity or tonnage. By considering each element carefully, you can ensure you purchase an AC unit that cools your home efficiently and economically.


Air conditioning plays a crucial role in making our homes comfortable, especially during hot or humid periods. A common mistake that many homeowners make is choosing an air conditioning unit based on budget alone, without considering the size of their room or home. This can result in inefficiency and higher energy costs. Therefore, it's imperative to understand how to determine the perfect AC size for your space.


1. Calculate Room Size:

The first step is to calculate the size of the room you wish to cool. Use a measuring tape to find out the length and width of your room in feet. Multiply these two numbers together to get the area in square feet.


2. Determine BTU (British Thermal Unit):

BTU refers to the amount of heat an air conditioner can remove from a room within an hour. The larger your room is, the higher BTU rating you will need.


Typically, for every square foot, you require 20 BTU. So if your room is 500 square feet, you'll need an AC with a 10,000 BTU rating.


3. Consider Additional Factors:

While square footage and BTU are fundamental factors, they are not the only ones you should take into account when choosing an AC unit for your space.

  • Insulation:Well-insulated rooms retain cool air better, reducing the load on your AC unit.

  • Number of occupants:If more than two people regularly occupy a room, you should add 600 BTUs per additional person.

  • Sunlight:Rooms with lots of sunlight need more cooling capacity – around 10% more BTUs.

  • Kitchen use:If you’re installing an AC in your kitchen, increase capacity by 4,000 BTUs due to heat generated from cooking.


4. Energy Efficiency Rating (EER):

EER indicates how much cooling a system puts out for each unit of energy it consumes; basically its energy efficiency level. A system with higher EER will be more efficient and could save you money in terms of electricity bills over time.


With all these factors combined together –room size calculation according to square footage and ceiling height, correct amount of BTU’s considering number of occupants and exposure to sunlight among others– it becomes easier for homeowners or buyers like yourself not only understand what exactly fits their individual needs but also help them make informed decisions when shopping around various models available on market today.


Remember that oversized air conditioners do not equate better performance - they cycle on and off quickly which increases energy consumption and decreases efficiency while not effectively dehumidifying your space; undersized ones will constantly struggle keeping up with cooling demand resulting in discomfort especially during hot summer months as well as high electrical bills due unending operation. Therefore understanding how to correctly size your air conditioner is key for maximum comfort and energy efficiency.


Understanding AC Service in Chantilly, VA and its Performance Influences due to Climate and Weather

Air conditioning systems are designed to provide comfort by reducing the indoor temperature and controlling humidity levels. However, the performance of an AC system is influenced significantly by external factors, particularly climate and weather conditions. Understanding these influences can help homeowners make informed decisions about their HVAC systems, including when to schedule maintenance, what type of unit to purchase, and how to optimize usage for energy efficiency.


Air Conditioner Contractors in Chantilly, VA and Their Role in AC Performance

Climate refers to long-term weather patterns in a specific region. It affects air conditioning systems in several ways.

  • Temperature: The efficiency of most air conditioners decreases as outdoor temperatures rise. This is because the condenser unit must work harder to dissipate heat into the surrounding air.

  • Humidity: High humidity levels can also affect AC performance. Air conditioners remove moisture from indoor air as part of their cooling process. If outdoor humidity is high, the system has to work harder to maintain comfortable indoor conditions.

  • Solar radiation: The amount of sunlight your home receives can affect how hard your AC works. Homes that receive a lot of direct sunlight may need more powerful systems.


Effect of Weather on AC Performance

While climate affects long-term decisions about HVAC systems, daily weather conditions also impact AC performance.

  • Temperature fluctuations: Rapid changes in temperature can cause stress on your system as it attempts to maintain a consistent indoor environment.

  • Thunderstorms: Severe weather events like thunderstorms can cause power surges that may potentially damage your unit. Wind-driven debris could also cause physical harm.

  • Snow and ice: In regions with cold seasons, snow and ice can block exterior components of an HVAC system, leading to reduced efficiency or even damage.


Adapting Your Air Conditioning System

Taking into account these influences, here are some ways you might optimize your AC's performance:

  1. Proper sizing: Ensure your AC unit is the right size for your home, taking into account factors such as local climate and the size and layout of your house.

  2. Regular maintenance: Schedule routine professional maintenance to keep your system running smoothly. Maintenance should include checking for potential damage caused by severe weather conditions.

  3. Invest in a programmable thermostat: This helps manage temperature fluctuations, reducing stress on your AC system.

  4. Install protective features: For colder climates, consider using weatherproof covers for outdoor units to protect against snow and ice.


Climate and weather have a significant impact on AC performance but understanding these impacts can help homeowners maintain their systems more efficiently. By considering long-term regional climate and daily weather changes, individuals can optimize their air conditioning use for comfort, longevity of the system, and energy savings.


When it comes to air conditioning systems, understanding capacity and tonnage is crucial. These two concepts play a pivotal role in determining whether an AC unit will effectively cool your space or not. Let's explore these concepts in detail.


What is AC Capacity?

In simplest terms, the capacity of an air conditioner refers to its ability to extract a certain amount of heat from a room in a given period. An AC unit with higher BTU ratings means it has a greater cooling capacity, making it capable of cooling larger spaces more efficiently.

  • 5,000 to 6,000 BTU: Ideal for small rooms up to 300 square feet

  • 7,000 to 8,500 BTU: Suitable for medium rooms up to 350 square feet

  • 10,000 to 12,500 BTU: Perfect for large rooms up to 650 square feet

  • 14,000+ BTU: Recommended for extra-large rooms over 650 square feet

Remember that these are estimated capacities. The actual cooling effect may vary based on other factors such as insulation and number of people present.


Exploring Air Conditioner Services in Chantilly, VA Systems

The term 'tonnage' may seem odd when we talk about air conditioners. In fact, it has nothing do with weight but instead refers to the cooling capacity of an AC unit. One ton equals approximately 12,000 BTUs per hour.

Historically, this term originated from the amount of heat required to melt one ton of ice within 24 hours.

  • A 1-ton AC unit can remove about as much heat as melting one ton of ice.

  • A 2-ton unit corresponds roughly with the heat removal equivalent of two tons of melted ice per day.

By this logic,

Air Conditioner Size (Tons)

Cooling Capacity (BTUs per hour)

1 Ton

12000 Btu/hr

1.5 Ton

18000 Btu/hr

2 Ton

24000 Btu/hr

2.5 Ton

30000 Btu/hr

3 Ton

36000 Btu/hr


Finding Balance Between Capacity and Tonnage

It's not about simply choosing the highest capacity or tonnage for your air conditioner. Finding the perfect balance is key here because if you choose an over-capacity model then energy efficiency would be compromised due to frequent on-off cycles; whereas an under-capacity model will have trouble adequately cooling your space.

Therefore, other factors must be considered while choosing an air conditioner such as room size, climate conditions and insulation levels among others.

A professional HVAC technician should be able to guide you through calculating the ideal capacity and tonnage based upon your specific circumstances. Always remember that correct sizing is critical for achieving optimal performance from your cooling system.


Delving into the Concepts of Capacity and Tonnage in Air Conditioners

It's essential when purchasing an air conditioning (AC) system for your household to comprehend two crucial factors – capacity and tonnage. In this section, we will delve into these concepts, helping you to understand their significance and how they influence the performance and efficiency of your AC system.


Understanding Air Conditioning Service in Chantilly, VA

Capacity in an air conditioning unit refers to the amount of heat it can remove from a room within a specific period.

In simpler terms, if an AC unit has a higher BTU rating, it means that it can cool a larger space more efficiently. However, it's also essential not to oversize your AC because this can lead to short cycling and increased energy bills.

Here are some common capacities for residential air conditioners:

  • 5,000 BTUs: Suitable for rooms up to 150 square feet

  • 8,000 BTUs: Suitable for rooms between 150-350 square feet

  • 10,000 BTUs: Suitable for rooms between 350-450 square feet

  • 12,000 BTUs: Suitable for rooms between 450-550 square feet


Understanding Tonnage in Air Conditioning

Tonnage in an air conditioning unit essentially means how much heat the unit can remove from space within one hour. A ton denotes that an AC has the capacity to cool approximately 12,000 BTUs per hour. Hence a two-ton air conditioner would be able to handle about 24,000 BTUs per hour.

Here's an overview of tonnage suitability:

  • One Ton: Suitable for up to approx. 500 sq ft.

  • 1. 5 Tons: Suitable for between 500-700 sq ft.

  • Two Tons: Suitable for between 700-1000 sq ft.

  • Three Tons: Suitable for between 1500-1800 sq ft.

  • Four Tons: Suitable for between 2100-2300 sq ft.


Choosing the Best Air Conditioning Repair Contractor in Chantilly, VA

Several factors can influence the capacity and tonnage choice for your air conditioning unit.

  • Room size (length, breadth, and height)

  • The number of windows and doors

  • Quality of insulation

  • Climate region

  • Occupancy level

  • Heat-producing appliances in the room

By understanding these concepts, you'll be better equipped to make an informed decision when buying an air conditioning unit. This will ensure that your unit is efficient, cost-effective, and provides optimal cooling for your home. Always remember to consult with a professional HVAC technician who can accurately calculate the appropriate AC size based on these factors.
