7 AC Repair Signs Every Homeowner Should Know
As the sun returns and temperatures begin to rise in West Sacramento, CA, it is evident that summer is just around the corner. You’ll want to make sure your air conditioner is set to keep you cool. But how can you know if it needs some attention? If you notice any of the following warning signals, you most certainly require an air conditioner repair.
AC System is Blowing Warm Air
Nobody buys an air conditioner just to appear cool. An air conditioner has a specific purpose: to keep your family comfortable during the hot, sticky summer months.

Limited Airflow from Vents
Poor airflow is a typical indicator that your air conditioner isn’t working properly or that there is a clog stopping air from passing through your home’s ducting. A clogged air filter, a broken motor, or anything more catastrophic could be the fault. If limited airflow is a frequent problem in your house, we may consider investing in an energy-recovery ventilator. It can help your air conditioner by exchanging stale air for fresh air each time it cycles. Your air conditioner may also benefit from zoning. They can ensure that you have adequate ventilation and cooling power where you need it most.
Loud Noise Coming from the AC Unit
Most air conditioners produce low-level noise when they start up and shut down. However, loud, sudden, or strange noises may indicate serious difficulties with your cooling system.
Rattling or buzzing noises can suggest a loose element, whereas whistling or grinding noises can indicate a more serious issue. This type of problem will not normally go away on its own, therefore a professional tune-up is required. Our team will identify the root of the problem and propose a solution to keep your family cool and comfortable all season.
Unusual Odors When AC is Turned On
Unusual odors can be created by a variety of factors, including mold, electrical faults, or clogged air filters. Mildew odors frequently imply mold growth, which can pose health issues for you and your family. A burning odor can indicate an electrical problem, whereas a filthy or clogged air filter can provide a musty or stale odor.
Water Leakage
If you discover any water or refrigerant leaks around your AC unit, it’s a strong indication that you need professional air conditioning repair service as soon as possible. Water leaks might be caused by a clogged condensate drain line or a faulty evaporator coil, but refrigerant leaks are typically caused by a damaged or worn-out component. Leaks can cause major harm to both your air conditioner and your house. Unresolved leaks can cause mold growth, structural damage, poor energy efficiency, reduced cooling capacity, and potential health risks. If you find any leaks, switch off your AC and contact a professional right away.

Insufficient Humidity Removal by the AC
During the months of spring and summer, expect sticky conditions outside. However, this does not imply that you should be exposed to high humidity levels indoors. Your air conditioner should regulate humidity levels automatically. If your cooling system is unable to keep moisture levels within a reasonable range, you require an air conditioner repair. We’ll swiftly assess the problem and advise you on whether your air conditioner requires a simple re-calibration or whether you should choose a whole-house dehumidifier instead.
Rising or High Electric Bill
Another sign that your air conditioning system needs to be replaced or repaired is a rapidly rising energy bill without any additional usage. This problem could be caused by a damaged thermostat switch, leaks in your HVAC system’s ducts, or an older air conditioning unit. Regardless matter the source, your unit will require repairs.
AC Unit Has Reached the End of Its Lifespan
If your air conditioning unit is at least ten years old, you should be grateful for its longevity and start looking for a replacement. Air conditioners typically don’t last more than a decade. These indicators are valuable reminders of how to immediately identify a problem and, in many situations, can help you avoid having to replace your HVAC unit entirely.
Maintaining a suitable temperature in your home throughout the summer requires a number of well operating mechanics. If you notice any of these seven indicators, call a professional HVAC expert. Attempting to do the repairs yourself can result in unnecessary charges if something goes wrong.
