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.

Advanced features can enhance the comfort and convenience of an AC unit.
Wi-Fi Connectivity:Allows you to control your AC through a smartphone app.
Sleep Mode:Adjusts temperature during the night for optimal sleep comfort.

Remember that professional installation by a licensed HVAC technician is crucial to ensure optimal operation and longevity of your unit. And finally, regular maintenance can help keep your AC running efficiently for years to come.
An important factor in selecting the right air conditioner for any space is understanding the role of room size. Room size significantly impacts the effectiveness and efficiency of your air conditioning system. Therefore, it's crucial to carefully assess your room dimensions before making a purchase.
The main reason why room size matters can be found in the basic working principle of an air conditioner. Air conditioners function by extracting warm air from a room, cooling it down with the help of a refrigerant, and then releasing it back into the space. Logically, the larger the room, the larger amount of warm air that needs to be cooled down. This implies that a small air conditioner may struggle to cool a large room effectively and will work harder than necessary, leading to more energy consumption and higher bills.

Choosing the Right Air Conditioning Service in Herndon Town, VA

To determine how powerful an AC unit you need, first measure your room size. This can be achieved by multiplying the length by width for square or rectangular rooms.
After obtaining this figure (usually in square feet), you'll need to determine how many British Thermal Units (BTUs) are required to efficiently cool that space.
Here is a simple guideline based on square footage: Up to 150 square feet: 5,000-6,000 BTUs 150-250 square feet: 7,000-8,000 BTUs 250-300 square feet: 8,000-10,000 BTUs 300-450 square feet: 10,000-12,000 BTUs
Please note that these values are estimates and might vary based on other factors such as ceiling height and sun exposure.

Air Conditioner Services in Herndon Town, VA: Influencing Factors in AC Unit Selection

While it's apparent that room size plays a significant role in choosing an air conditioning unit's capacity, other factors should also be considered:
Location: If your home is located in an area with high humidity or extremely hot temperatures, you may need an air conditioner with higher BTU capabilities.
Insulation: Homes with poor insulation may require more cooling power as heat can easily infiltrate these spaces.
Occupancy: The more people using a room regularly will increase heat output and require more cooling power.
Appliances: Rooms with heat-generating appliances like ovens or computers may also need more powerful units.
By taking into consideration all these factors including room size when selecting an air conditioning unit ensures optimal cooling performance and energy efficiency. It might seem like quite a task but investing time at this stage ensures comfort and savings in future.

Exploring AC Service in Herndon Town, VA: Choosing Between Split and Window AC for Optimal Cooling Experience

When it comes to cooling your home or office, choosing the right type of air conditioner is crucial. Two common types are window air conditioners and split air conditioners. Both types can effectively cool a room, but they come with their own pros and cons.

Finding an Air Conditioning Repair Contractor in Herndon Town, VA

The indoor unit is installed inside the room you want to cool, while the outdoor unit contains the compressor and is installed outside.
Pros of Split AC
Efficiency: Compared to window units, split ACs are generally more efficient. They consume less energy for the same amount of cooling.
Noise Level: Since the compressor (the noisiest part of an AC) is located outside in a split AC, they are usually quieter than window units.
Aesthetic Appeal: Due to their modern design, split ACs often blend better with interior designs compared to window units.
Cons of Split AC
Installation Cost: Installation of split ACs can be quite expensive as it requires professional installation.
Maintenance: Maintaining a split system can be more challenging due to its two-part design. Servicing it may require professional assistance.
Air Conditioner Contractors in Herndon Town, VA
Window air conditioners are compact units designed to fit in most standard windows or walls. They have all components (including the compressor) housed in a single box.
Pros of Window AC:
Cost Effective: Window units generally cost less than split systems both in terms of upfront cost and installation.
Easy Installation and Maintenance: As these are single-unit systems, both installation and maintenance can be simpler and cheaper than split systems.
Cons of Window AC:
Noise Level: Window ACs can be quite noisy as all components are located in one unit, inside the room.
Limited Installation Options: Given that these units need to be installed either in a window or an external wall, your placement options are limited.
To summarize, your choice between a split AC and window AC should depend on multiple factors such as budget, maintenance preferences, noise tolerance and aesthetic considerations. It's always beneficial to weigh the pros and cons before making a decision. The ultimate aim is to ensure the cooling system provides an optimal experience for your specific needs and circumstances.
We understand that choosing the right air conditioner can be a daunting task, but with careful analysis and understanding, it can be done effortlessly. This section will guide you on how to narrow down your options and select the best air conditioning unit for your needs.
Consider Your Space
The kind of space where you plan to install an AC unit plays a significant role in your decision. For instance, if you're looking at cooling a single room like a bedroom or home office, then a window AC or portable air conditioning unit would be sufficient. These units are cost-effective and relatively easy to install.
On the other hand, if you're aiming to cool multiple rooms or an entire house, then central AC systems or ductless mini-split systems might be more suitable. These systems are more energy-efficient when cooling large spaces and provide consistent temperature control.
Energy Efficiency
Energy efficiency is another critical factor to consider when selecting an AC unit. Always look for units with high Energy Efficiency Ratio (EER) ratings as they consume less power for the same amount of cooling compared to units with low EER ratings.
Your budget is often one of the most influential factors in your final decision. Prices for air conditioners vary widely based on their type, brand, capacity, features, and installation costs.
Other Features
Modern air conditioners come with various features for added comfort and convenience such as programmable thermostats, variable fan speeds, sleep settings, and Wi-Fi control. These features may not be necessary for everyone, but they can enhance your air conditioning experience and are worth considering.
Installation and Maintenance
Consider the installation process of the AC unit you choose. Whereas window units can be self-installed, split systems or central AC systems require professional installation. Maintenance requirements should also be taken into account as certain types of AC units require more regular upkeep than others.
Choosing the right type of AC for your needs requires careful evaluation of all these factors. It is advisable to consult with a professional HVAC technician while making this decision as they can give expert advice based on your specific circumstances.
When contemplating the replacement of an air conditioning unit, it is important to make a well-informed decision. A variety of factors can influence the choice of a new unit, from the type and size of the home to budget constraints.
Type and Size of Your Home: The characteristics of your home play a crucial role in determining what type of AC unit is best. For instance, if you live in a multi-story house, you might want to consider a split AC system that can cool multiple floors efficiently. On the other hand, if you live in a small apartment, a window AC might be sufficient.
Energy Efficiency: With rising energy costs and increasing awareness about environmental conservation, energy efficiency has become an important factor when choosing an AC unit. Look for units with high Energy Efficiency Ratio (EER) ratings as they tend to consume less electricity while providing optimal cooling.
Budget: While it might be tempting to opt for the cheapest option available, remember that an AC is a long-term investment. Consider not just the initial cost but also the long-term operating costs.
Capacity: The capacity of an AC unit should align with the size and cooling requirements of your space. Undersized units will struggle to cool your space efficiently and may lead to higher electricity bills due to constant operation.
Brand Reputation: As with any major appliance purchase, it's advisable to choose a reputable brand that offers good customer service and warranty coverage.
Installation Requirements: Different types of AC units have different installation requirements which can affect the overall cost and feasibility.
Before making any decisions about replacing your air conditioning unit, it may be beneficial to consult with HVAC professionals who can provide personalized advice based on your specific circumstances.
It can be helpful to draw up a comparison table to weigh the pros and cons of different units with respect to your unique requirements. This can not only aid your decision-making process but also prevent any regrettable purchases down the line.
