AC FAQs and TIPS

Some of the most common reasons a central air system stops working are Freon Leaks - Freon has run too low, the air filters are blocked or dirty, the Evaporator coil is frozen over, or there is an electrical issue.

Several factors can lead to sudden cooling loss in an AC system, such as a clogged air filter,  condenser fan not turning, malfunctioning thermostat, insufficient refrigerant levels, or a defective compressor. For accurate diagnosis and resolution, enlisting the expertise of seasoned HVAC professionals like John’s Heating, Cooling, and Appliance Repair is recommended.

AC units may struggle in Georgia when the outdoor temperature surpasses 95 degrees. High temperatures challenge air conditioners by increasing the workload to cool indoor spaces, pushing systems to their limits. The extreme heat makes it difficult for AC units to dissipate heat effectively, potentially reducing cooling efficiency. This increased demand strains the system, impacting overall performance. Regular maintenance, proper insulation, and energy-efficient practices become crucial in mitigating these challenges and ensuring optimal cooling during Georgia's intense summer temperatures.

Having to add refrigerant, like Freon, to your AC system every year is usually a sign that something is wrong, not something normal. If you need to add refrigerant often, getting a qualified HVAC professional to check and fix any leaks is crucial. They can determine what's causing the problem and ensure your AC system works well, saves money, and is eco-friendly. Regular check-ups by professionals can stop issues from happening and keep your AC working smoothly for a long time.

The SEER (seasonal energy efficiency ratio) measures the efficiency of your heating and cooling equipment. The SEER is the amount of cooling your system will deliver per dollar spent on electricity compared to other systems. For example, a 2-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER, the more efficient the system will be. Any given unit's SEER rating can range from 13 to 21.

The SEER (seasonal energy efficiency ratio) measures the efficiency of your heating and cooling equipment. The SEER is the amount of cooling your system will deliver per dollar spent on electricity compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER, the more efficient the system will be. Any given unit's SEER rating can range from 13 to 21.

Each split system cooling unit has a nominal SEER rating. This rating can be increased by upgrading the same series of indoor units. The SEER rating of a system is based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner) and the indoor equipment (evaporator coil and furnace or air handler) play a vital role in the total rating.

When your air conditioning (A/C) system functions correctly, it cools your home. If the AC unit is appropriately sized for your home, it fulfills the dual role of cooling and dehumidifying the indoor air. The AC unit cools and dehumidifies air by drawing warm, moisture-laden air over cold evaporator coils. As the air cools, water vapor condenses into liquid (The spot in your yard that is always wet), reducing humidity. The cooled, dehumidified air is then circulated back into the living space. This is how we can get the cool, comfortable air we desire.

One of the most frequently asked questions pertains to the multitude of AC brands in the market. Not all brands are created equal, as cost, size, and cooling capabilities differ. It's crucial to contemplate investing in a system that not only delivers optimal cooling but also keeps energy costs in check. In essence, prioritize an air conditioner system that is energy-efficient.

For your specific equipment, there are many variables that affect life expectancy, including, of course, the regularity of routine maintenance. 10-12 Years is Normal

When determining whether to repair or replace your air conditioner, it's crucial to ensure you're making a cost-effective decision. If your system has surpassed a decade in age, replacing it might be a prudent choice. Older units often incur escalating repair expenses, and with the system nearing the end of its lifespan, continual repairs could become a costly cycle. On the other hand, if your air conditioner is still relatively new, opting for a repair may be the most economical and sensible solution. Regularly assessing the age and condition of your system can guide you in making informed decisions for optimal efficiency and financial savings.

While standard filters effectively maintain the cleanliness of your system and ductwork, they don't necessarily enhance indoor air quality. To achieve that, a media air cleaner is recommended. Positioned between the main return duct and the blower cabinet, a media filter significantly improves dust and particle removal, offering up to seven times the efficiency of a standard filter.

For even higher filtration, upgrading to a pleated media filter can effectively capture everything from dust to airborne viruses. It's essential to choose a filter that aligns with your blower's capacity for optimal performance.

Your heating and cooling systems exert considerable effort to fulfill their functions for your home daily. The consistent cycle of starting, stopping, and continuous operation can result in wear and tear on any machine if proper care and maintenance are neglected. Nevertheless, regular maintenance can significantly extend the lifespan of your heating or cooling unit and protect against many common equipment failures.

Scheduled preventive maintenance inspections can reveal leaks, rust, rot, soot, frayed wires, and corroded electrical contacts. I

Investing in a smart thermostat is a wise choice for those seeking to reduce energy consumption and lower utility bills without compromising on comfort.

Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats, you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

Setting your thermostat at a consistent temperature that aligns with your comfort preferences is vital. Maintaining a comfortable indoor environment is recommended by setting your thermostat to 72 degrees Fahrenheit when you're at home and awake. This ensures your comfort and helps in energy conservation and efficient system operation. Consider keeping the thermostat at the same temperature throughout the day and night to simplify your routine and potentially save on energy costs. Regularly monitor and adjust your thermostat settings to optimize performance and efficiency.

A WiFi thermostat offers several advantages compared to traditional thermostats:

Remote Control: One of the significant advantages is the ability to control your thermostat remotely. Using a mobile app or a web portal, you can adjust the temperature settings from anywhere with an internet connection. This is particularly useful if you want to change settings while away from home or forget to adjust the thermostat before returning.

Energy Efficiency: WiFi thermostats often have features like scheduling and learning capabilities. You can set specific temperature schedules, and some models learn your preferences over time, optimizing energy usage and potentially reducing utility bills.

Smart Home Integration: Many WiFi thermostats are compatible with smart home systems, allowing you to integrate them with other smart devices in your home. This integration enables more comprehensive control and automation of

Water leaking from your furnace often indicates a clogged drain line from the evaporator coil, which is not a direct issue with the furnace. The evaporator coil, located on top of the furnace, extracts moisture from the air during the cooling process. This condensation usually exits through a drain line. When this drain line becomes clogged with debris or algae, the water backs up, causing leakage. The water originates from the evaporator coil, not the furnace itself. Regular maintenance, such as clearing the drain line, is crucial to prevent clogs and water damage, ensuring your HVAC system operates efficiently.
