Is Your AC Showing These Signs? Common Air Conditioning Issues & Unique's Solutions
Air conditioning systems often give signs before a complete breakdown. Recognizing these symptoms early can help prevent more extensive damage and costly repairs. Our expert technicians are equipped to diagnose and resolve a wide range of AC problems, ensuring your Chesterfield home stays cool and comfortable.
AC Not Cooling / Blowing Warm Air
- Symptoms: Your unit is running, but the air coming from the vents isn't cool, or it feels lukewarm. You may notice your AC running constantly without achieving the desired temperature.
- Possible Causes: This could indicate a refrigerant leak, a failing compressor, a severely clogged air filter restricting airflow, or dirty evaporator coils.
- Unique's Solution: Our diagnostic process includes precise leak detection using advanced tools, checking refrigerant levels, and thoroughly inspecting the compressor and coils. We can repair leaks, recharge refrigerant, or clean/replace components to restore proper cooling.
Strange Noises (Banging, Hissing, Squealing)
- Symptoms: You hear unusual sounds like rattling, grinding, squealing, or hissing coming from your indoor or outdoor unit.
- Possible Causes: Rattling often points to loose parts or debris. Grinding might indicate a problem with the fan motor bearings. Hissing typically signifies a refrigerant leak. Squealing could be a worn belt or fan motor issue.
- Unique's Solution: We meticulously inspect all internal components, including fan motors, belts, and refrigerant lines. Our technicians are skilled in identifying the source of the noise and performing the necessary repairs, from tightening loose parts to replacing worn motors or fixing leaks.
AC Not Turning On / Frequent Cycling
- Symptoms: Your air conditioner fails to start, or it turns on for a short period, then quickly cycles off repeatedly (short cycling).
- Possible Causes: Thermostat malfunctions, electrical issues (like a tripped breaker or faulty wiring), a clogged condensate drain line causing a safety shut-off, or low refrigerant leading to an overload.
- Unique's Solution: We perform comprehensive electrical checks, assess thermostat calibration, clear any obstructions in the condensate drain line, and address refrigerant issues to ensure your system starts and runs consistently without unnecessary interruptions.
Leaking Water / Frozen Coils
- Symptoms: You notice puddles of water around your indoor AC unit, or you see ice buildup on the refrigerant lines or evaporator coil.
- Possible Causes: A clogged condensate drain line is a common culprit for water leaks. Frozen coils often result from low refrigerant levels, restricted airflow due to dirty filters, or a malfunctioning blower fan.
- Unique's Solution: Our service includes clearing clogged drain lines, accurately diagnosing and addressing refrigerant leaks, recharging the system if needed, and optimizing airflow by cleaning coils or inspecting the blower fan to prevent ice formation.
Uneven Cooling & Hot Spots
- Symptoms: Some rooms in your Chesterfield home are significantly warmer than others, despite the AC running.
- Possible Causes: This issue can stem from leaky or poorly insulated ductwork, improper system sizing for your home’s specific layout, or airflow imbalances.
- Unique's Solution: We conduct thorough ductwork inspections, seal leaks, and assess your system's overall airflow. Our technicians can help balance airflow to different zones, ensuring consistent and comfortable temperatures throughout your entire home.

Is It Time for a New AC? The Repair vs. Replace Dilemma
Deciding whether to repair your existing air conditioner or invest in a new one is a common question for Chesterfield homeowners. Our experts provide honest, unbiased advice to help you make the most cost-effective and comfortable decision for your home.
Consider these factors:
- Age of Unit: If your AC unit is 10-15 years old or older, it may be nearing the end of its typical lifespan (15-20 years for ACs, heat pumps potentially longer). Older units are often less energy-efficient and more prone to breakdowns.
- Frequency of Breakdowns: If your system requires frequent repairs, the cumulative cost can quickly outweigh the benefit of keeping it.
- Cost of Repair: If the cost of the repair is more than 50% of the cost of a new, comparable unit, replacement is often the more economical choice in the long run.
- Energy Efficiency: Newer AC models are significantly more energy-efficient than older ones, potentially leading to substantial savings on your monthly utility bills.
Understanding the "$5,000 Rule": A helpful guideline often used is the "$5,000 rule." Multiply the age of your air conditioning unit by the estimated cost of the repair. If the resulting number exceeds $5,000, it's generally advisable to consider replacing the unit rather than repairing it. While this is a rule of thumb, our technicians will provide a detailed assessment specific to your situation, helping you weigh the pros and cons to make the best decision for your budget and comfort.

Using a high-efficiency MERV-rated filter can also improve indoor air quality.
- Keep Outdoor Unit Clear: Ensure the area around your outdoor condenser unit is free from debris, leaves, grass clippings, and shrubs to allow for proper airflow.
- Don't Block Vents: Make sure furniture or drapes aren't obstructing your indoor vents, which can restrict airflow and reduce efficiency.

Your Chesterfield AC Repair Questions Answered
What is the average life expectancy of an air conditioner?
Most central air conditioning units have a life expectancy of 15 to 20 years. However, this can vary based on usage, maintenance quality, and the initial quality of the system. Heat pump systems might last slightly longer, while furnaces paired with AC units may have slightly different lifespans for each component. Regular professional maintenance can significantly contribute to extending your unit's life.
What is the $5,000 AC rule?
The "$5,000 rule" is a guideline used to help homeowners decide whether to repair or replace their AC system. It suggests that if the age of your unit multiplied by the cost of the repair exceeds $5,000, it's generally more cost-effective in the long run to consider a replacement rather than a repair. For example, if your 10-year-old unit needs a $600 repair (10 x $600 = $6,000), you might consider replacement. This rule helps factor in the diminishing returns of repairing older, less efficient systems.
How often should I change my air filter?
For most standard 1-inch pleated air filters, it's recommended to check them monthly and change them every 30 to 90 days. Factors like pets, allergies, the number of occupants, and overall indoor air quality can necessitate more frequent changes, sometimes as often as every 30 to 60 days. Using high-efficiency filters (with a higher MERV rating) can also impact change frequency but offers superior air quality benefits.
Should I have my air conditioner serviced every year?
Yes, annual professional maintenance for your air conditioning system is highly recommended. Regular servicing, ideally in the spring before peak cooling season, helps ensure your unit operates at peak efficiency, prevents costly breakdowns, extends its lifespan, and can even fulfill warranty requirements. It’s a proactive step that saves money and enhances comfort.
Why is my AC fan so loud?
A loud AC fan can indicate several issues. Common causes include dirty or unbalanced fan blades, loose components within the unit, worn-out motor bearings, or a problem with the fan motor itself. Hissing noises might indicate a refrigerant leak. Our technicians can diagnose the specific cause and perform the necessary repairs to quiet your system.
What kind of warranty do you offer on AC repairs?
Unique Heating & Cooling stands behind the quality of our work. We offer a comprehensive warranty on both the parts we install and the labor performed during your AC repair. Specific warranty details will be provided at the time of service, ensuring you have complete peace of mind with our repairs.
