Cerritos Central AC Repair

Today’s central air conditioners are robust systems designed to run reliably for many years. However, all machines need a little TLC now and again. Here are the most common signs that your AC needs service as soon as possible.

  • Your Air Conditioner Makes Unusual Noises One of the surest signs that something isn’t right with your air conditioner is if it makes sounds you’ve not heard before, such as rattling, squealing, or grinding; call a professional technician to investigate.
  • Your Air Conditioner Short Cycles When an air conditioner starts, runs for a few seconds and shuts down, it’s known as short cycling. Many factors lead to short cycling, including dirty air filters, low refrigerant, or damaged evaporator coils. An AC that short cycles won’t provide you with the comfort you need, and it puts excess wear and tear on the system.
  • Fluid Leaks Another problem requiring a call to a service pro is a fluid leak near the condenser. This fluid is usually refrigerant, which is crucial to your air conditioner’s performance. Low refrigerant levels mean the system can’t keep you cool and can cause the system to fail completely.
  • Your Air Conditioner Responds Slowly Does your air conditioner take forever to adjust to the thermostat changes? Typically, an AC system should power up in about 30 seconds after adjusting the thermostat, so if your system responds too slowly or not at all, it could be a wiring issue or a problem with the thermostat itself.
  • Uneven Cooling Finally, if you notice some rooms in your house are cooler than others, it usually means your air conditioner is struggling to provide even cooling. Sometimes, a blocked or closed register is the problem; however, in other cases, you need a system tune-up.

If you experience these or any other annoying issues with your air conditioner, call the experts at Lambert Heating and Air Conditioning as soon as possible.

When to Replace Your Air Conditioner

Modern air conditioners are robust and reliable systems; however, nothing lasts forever, and eventually, you’ll have to spring for a new unit. But how do you know when it’s time to stop sinking money into repairs and install a new system? Here are some tips to help you decide.

  • How Old Is Your Air Conditioner? The average lifespan of an air conditioner is about 15 years, with routine maintenance and upkeep. However, once your system reaches double digits, it’s best to replace it soon because repair costs will skyrocket the older it gets.
  • Skyrocketing Energy Costs Do you face sticker shock every month when you get your electric bill? Although energy costs continue rising, you should know what to expect every month. So, if your bills are higher than average, your HVAC system may be the culprit because air conditioners lose efficiency as they age.
  • Your Home Isn’t Comfortable Another obvious sign that your air conditioner may be ready for the scrap pile is if you can’t get comfortable no matter how you adjust the thermostat. Perhaps you’ve added on to your home, or your family has grown, and your air conditioner can’t keep up with the increased demand, or it could be the system is past its prime and ready to retire.
  • More Expensive Repairs Old air conditioners that are out of warranty typically require expensive repairs. Often it’s more cost-effective to put the money you’d spend fixing your old system towards a new one.
