What Are the Signs that Your AC Needs to Be Repaired?
While the lack of cool air is a sure sign something is wrong with your air conditioner, not all symptoms of disrepair are as easy to detect.
Our Rapid City air conditioning repair technicians recommend scheduling service when:
- Your monthly utility bills have skyrocketed: Anytime there’s a spike in your energy bills, it could mean that your system is working harder to keep your home the cool temperature you desire. This could be due to a damaged part, clogged or leaking ductwork, or even dirty air filters.
- Your unit makes loud, unusual noises: While subtle noise from an air conditioner is normal, you should call a technician when you hear any grinding, groaning, rumbling, banging, or screeching noises.
- You have an increased humidity in your home: Even without the addition of a humidifier, your air conditioner is responsible for helping control humidity levels in your home. If you notice that it is hotter and rather sticky indoors, chances are you need your AC repaired. It’s important to get this issue addressed as soon as possible because moist environments can lead to mold growth.
- Your indoor air quality has decreased: Have you recently started coughing or sneezing more? Whether you have allergies or not, this could be due to poor indoor air quality and a faulty air conditioning unit.
- Your air conditioner takes a while to fully cool your property: If you notice that it takes a lot longer to cool your property, this could be due to damaged ductwork or leaking refrigerant.
- Your unit continues to cycle: Any time the temperature in your home drops below a certain setting, your air conditioner is designed to cycle on. However, if it cycles on and off more frequently, this is a sign that something is wrong.
- Your unit only emits warm air: If you’re only getting warm air from your AC unit and you’re sure the thermostat wasn’t switched to the heat setting, this is a tell tale sign that something is wrong.
- You smell foul odors coming from your AC: If you smell burning or a musty smell coming from your air conditioner, it could mean that there are burnt wires or that you have mold growing within your ductwork.
How to Prevent Costly AC Repairs
Regular AC maintenance is the key to avoiding expensive repairs and ensuring your system runs efficiently for years to come. Here are some preventive steps you can take:
- Change or Clean Your Air Filters Monthly: Clogged filters reduce airflow, causing your AC to work harder and increasing energy costs.
- Schedule Professional Maintenance Annually: A licensed HVAC technician can inspect and clean components, ensuring optimal performance.
- Keep Your Outdoor Unit Clear: Remove debris, leaves, and dirt around your condenser to maintain proper airflow.
- Check Refrigerant Levels: Low refrigerant can indicate a leak, which can damage your compressor if left unaddressed.
- Seal Ductwork Leaks: Leaky ducts can cause energy loss, making your AC less efficient and increasing utility bills.
- Test Your Thermostat: Ensure your thermostat is properly calibrated and placed away from heat sources to avoid inaccurate readings.
Taking these steps can extend the life of your AC and prevent costly breakdowns.
Understanding the Repair Timeline for Your AC Unit
The time it takes to fix a broken AC unit can vary depending on the specific problem and the availability of parts. In general, simple issues like a clogged filter or a tripped circuit breaker can be resolved quickly, often within a few hours. However, more complex problems, such as a malfunctioning compressor or a refrigerant leak, may take longer to fix. In such cases, it could take a few days or even up to a week to complete the repair.

Commonly Asked Questions
How often should I replace my AC filter?
It’s recommended to replace or clean your AC filter every 1-3 months, depending on usage and environmental factors. Homes with pets or high dust levels may require more frequent changes. A clean filter helps maintain airflow efficiency and improves indoor air quality.
What is the average lifespan of an air conditioning unit?
Most air conditioning units last between 10-15 years with proper maintenance. Regular servicing, timely repairs, and filter replacements can extend the lifespan of your unit. If your system is over a decade old and frequently needs repairs, it may be time to consider a replacement.
Can I repair my AC unit myself?
While some minor maintenance tasks like changing the air filter or cleaning debris from the condenser can be done by homeowners, most AC repairs require a professional. Handling electrical components or refrigerant without proper training can be hazardous and may void your warranty.
Why is my AC leaking water?
Water leaks from an AC unit are often caused by a clogged condensate drain, frozen evaporator coils, or a malfunctioning pump. Regular maintenance can help prevent these issues and keep your system running smoothly.
What’s the best thermostat setting for energy efficiency in Rapid City?
For optimal efficiency, set your thermostat to 78°F in the summer when you're home and increase it slightly when you're away. A programmable or smart thermostat can help manage temperatures automatically and reduce energy costs.
What size AC unit do I need for my home?
The right AC size depends on your home’s square footage, insulation, and layout. A professional HVAC technician can perform a load calculation to determine the ideal unit size for maximum efficiency and comfort.
