Most Common Air Conditioning Questions

Understanding your air conditioning system helps you make informed decisions about its care. We have answered some of the most common questions our Chesterfield customers ask about AC services. This information can help you better understand installation, maintenance, and repair needs.

When your air conditioner is running but not blowing cold air, it is one of the most common and frustrating HVAC problems. The issue can stem from several potential causes, ranging from simple fixes to more complex mechanical failures. One of the first things a homeowner should check is the thermostat settings. Ensure that the thermostat is set to “cool” and the temperature is set several degrees lower than the current room temperature. Also, check the fan setting; if it is set to “on” instead of “auto,” the fan will run continuously, circulating unheated air between cooling cycles, which can make it seem like the AC is not working.

Another very common culprit is a dirty or clogged air filter. The air filter’s job is to trap dust and debris, but if it becomes completely blocked, it will severely restrict airflow over the evaporator coil. This lack of warm air can cause the coil to get too cold and freeze over, turning into a block of ice. When this happens, air cannot pass through it to be cooled, and you will get very weak or warm airflow from your vents. A frozen coil is a clear sign of an airflow problem or, in some cases, a low refrigerant level.

If the filter and thermostat are not the issue, the problem is likely more technical. The system could be low on refrigerant due to a leak. Refrigerant is the substance that absorbs heat from your home’s air, and without the correct amount, the system cannot cool. Other potential issues include a dirty outdoor condenser unit that cannot properly release heat, a faulty capacitor that prevents the compressor from starting, or a failing compressor itself, which is the heart of the system. These issues all require a professional diagnosis and repair from a certified technician to resolve safely and effectively.

For optimal performance, efficiency, and longevity, your air conditioner should be professionally serviced once a year. The ideal time for this annual maintenance visit, often called a tune up, is in the spring. Scheduling your service before the hot summer weather arrives in Chesterfield ensures that your system is clean, inspected, and ready to handle the heavy workload of the cooling season. This proactive approach allows a certified technician to identify and address any potential issues, like a wearing part or a low refrigerant level, before they can cause a sudden and inconvenient breakdown on a scorching hot day.

Consistent annual maintenance is key to the health of your cooling system. Skipping a year allows dirt and grime to build up on critical components like the evaporator and condenser coils. This buildup acts as an insulator, forcing the system to run longer and work harder to cool your home, which leads to significantly higher energy bills. This added strain also causes excessive wear and tear on parts like the compressor and fan motors, which can shorten the lifespan of your air conditioner and lead to more frequent and costly repairs over time.

Furthermore, most air conditioner manufacturers require proof of regular annual maintenance as a condition of their parts warranty. If a major component fails and you need to file a warranty claim, the manufacturer may require service records. Without them, your claim could be denied, leaving you to pay the full cost of an expensive part. By having Lolich Heating and Cooling perform your yearly tune up, you are not only protecting the physical health of your system but also preserving your valuable warranty coverage, making it a wise and necessary investment.

SEER stands for Seasonal Energy Efficiency Ratio, and it is the primary measurement of an air conditioner’s energy efficiency. A SEER rating indicates how much cooling output a system produces for each unit of electrical energy it consumes over an entire cooling season. In simpler terms, a higher SEER rating means a more energy efficient air conditioner. A more efficient unit will use less electricity to cool your home to the same temperature as a less efficient unit, which translates directly into lower monthly utility bills during the summer.

The U.S. Department of Energy sets minimum SEER rating requirements for all new air conditioners sold in the country, and these minimums can vary by region. When you are shopping for a new air conditioner, the SEER rating will be prominently displayed on the yellow EnergyGuide label. While systems with higher SEER ratings typically have a higher upfront purchase price, the long term savings on your electricity bills can often offset this initial investment over the life of the system, making it a very cost effective choice.

When our comfort advisors help you select a new air conditioner for your Chesterfield home, we will explain the different SEER ratings available and help you understand the potential long term savings. We can calculate an estimated payback period for a higher efficiency unit based on your expected usage and local electricity rates. This allows you to make an informed decision that balances your upfront budget with your long term financial goals. Choosing a unit with a good SEER rating is one of the best ways to manage your summer energy costs.

Deciding whether to repair or replace an aging air conditioner is a significant decision for any homeowner. The choice typically depends on three main factors: the age of the system, the cost of the needed repair, and the system’s overall efficiency. Most central air conditioners have an operational lifespan of about 10 to 15 years. If your unit is in this age range or older, it is often more sensible to put your money toward a new, reliable system rather than continuing to invest in an old one that is likely to have more component failures in the near future.

A good financial guideline to follow is the 50 percent rule. If the estimated cost of a repair is 50 percent or more of the cost of a new, comparable air conditioner, replacement is almost always the more economical choice. For example, if your old unit has a failed compressor, the repair cost can be very substantial. It rarely makes sense to spend thousands of dollars repairing an old, inefficient unit that is out of warranty when that money could be used as a significant down payment on a new, highly efficient system that comes with a 10 year warranty.

Finally, consider the energy efficiency of your current system. AC technology has advanced dramatically over the last decade. A new air conditioner with a modern SEER rating will be significantly more efficient than a unit from 10 or 15 years ago. The monthly savings on your electricity bill can be substantial and will help offset the cost of the new system over time. Our honest technicians will always provide you with a clear, straightforward comparison of the repair and replacement options, giving you the information you need to make the best decision for your home without any sales pressure.

An air conditioner that has ice forming on its coils or refrigerant lines is a clear sign of an underlying problem. While it might seem counterintuitive, an AC unit freezing up is not a sign that it is working too well; it indicates a malfunction that is restricting its normal operation. The most common cause of a frozen air conditioner is restricted airflow. This is usually due to a severely clogged air filter. If the filter is blocked with dirt, it prevents enough warm room air from passing over the indoor evaporator coil. This causes the coil’s temperature to drop below freezing, and the condensation on the coil will turn to ice.

The ice will continue to build up, further blocking airflow until the entire coil is encased in a block of ice. This can also happen if the indoor blower fan is failing or if your air vents are closed or blocked by furniture, as these also restrict airflow. The first step you should take if you notice ice is to turn the system off to allow it to thaw and to check your air filter. If the filter is dirty, replacing it may solve the problem once the ice has melted completely.

Another major cause of a frozen AC unit is a low refrigerant level. Refrigerant is what the system uses to absorb heat, and when the level is low due to a leak, it causes the pressure in the system to drop. This drop in pressure makes the evaporator coil get much colder than it normally would, causing it to fall below freezing and form ice. This is a more serious problem that requires a certified technician to find and repair the leak and then recharge the system with the correct amount of refrigerant. Continuing to run a frozen AC can severely damage the compressor.

A standard air conditioning installation, where we are replacing an existing outdoor condenser and indoor evaporator coil, can typically be completed in one day. For most homes in the Chesterfield area, our professional installation team can finish a straightforward replacement in approximately 4 to 8 hours. We understand that being without air conditioning is an inconvenience, so we work efficiently and diligently to get your new system up and running as quickly as possible. We schedule installations to ensure we have ample time to do the job right without rushing.

The timeline can be longer if the installation is more complex. For example, if the project requires new refrigerant lines to be run or if there are significant modifications needed for the home’s ductwork, the job will take more time. Installing a system in a home that has never had central air before is also a more involved process. Our technicians will provide a clear and realistic timeline for your specific project during the initial consultation. We believe in setting clear expectations so you know exactly what the installation day will entail.

Our installation process is thorough and meticulous. It includes the safe removal and disposal of your old equipment, the careful placement and securing of the new outdoor and indoor units, and precise connection of the refrigerant and electrical lines. After the physical installation, we perform a complete system commissioning. This involves pressure testing, evacuating the lines, and charging the system with refrigerant. We then test the system’s performance to ensure it meets manufacturer specifications. Our goal is a perfect installation, and we dedicate the necessary time to achieve it.

A professional AC maintenance tune up from Lolich Heating and Cooling is a comprehensive service designed to ensure your system is clean, efficient, and reliable. Our certified technicians follow a detailed checklist to inspect and service every critical part of your air conditioner. The service begins with a thorough cleaning of both the outdoor condenser coils and the indoor evaporator coils. Clean coils are essential for efficient heat transfer; dirty coils force your system to work harder and use more energy, so this is a critical first step.

Next, our technicians will perform a series of electrical and mechanical checks. We will inspect and tighten all electrical connections to ensure safe operation. We test the system’s capacitors and relays, which are crucial for the proper startup of the motors, and we will measure the amperage draw of the compressor and fan motors to ensure they are not being overworked. The condensate drain line is also inspected and cleared of any blockages to prevent water leaks and potential property damage. We ensure all moving parts are properly lubricated to reduce friction and wear.

Finally, we check the system’s refrigerant level. An incorrect refrigerant charge, whether too low or too high, can drastically reduce efficiency and cause damage to the compressor. Our technician will use gauges to ensure the charge is at the manufacturer’s specified level. We also check the calibration of your thermostat and replace your air filter if needed. At the end of the visit, we provide you with a detailed report of your system’s condition. This complete service prepares your AC for a reliable and efficient summer performance.

Choosing a licensed and insured HVAC company like Lolich Heating and Cooling for your air conditioning needs is crucial for protecting your safety, your home, and your financial investment. A state license is proof that the company and its technicians have met rigorous standards for training, knowledge, and competency in the HVAC trade. Licensed technicians understand the complex building codes, electrical requirements, and safety protocols that govern AC installation and repair. This ensures the work is done correctly and safely, preventing the risks of electrical fires, refrigerant leaks, and improper system performance that can come from shod-tasting work.

Insurance is equally important for your protection as a homeowner. A reputable company will carry both general liability insurance and worker’s compensation insurance. General liability insurance protects your property; if an accident occurs during the service and your home is damaged, the company’s insurance will cover the cost of repairs. Worker’s compensation insurance protects you from liability if a technician is injured while working on your property. If you hire an uninsured contractor, you could be held personally responsible for medical bills and damages in the event of an accident.

Hiring a licensed and insured professional also protects your equipment’s warranty. Most manufacturers will void their warranty if the system is installed or serviced by an unlicensed individual. Furthermore, a professional company stands behind their work. We back our new installations with a 10 year warranty, a promise you will not get from an unlicensed handyman. The peace of mind, safety, and quality assurance that come from hiring a true professional are invaluable.
