If you've lived in Las Vegas for long, you know you can't live without a working air conditioner in your home. If your unit is starting to act up, you want to have it dealt with as soon as possible. You don't want to wait until it's seriously struggling or downright broken before you call a repairman. That said, you can only get ahead of a total breakdown if you recognize the signs of trouble. This list will help.

#1 The System Is Blowing Warm Air

Your air conditioner has one job—to keep your family comfortable during the hot and muggy summer months. During the sweltering time of year, you need an air conditioner that functions properly. If your unit isn't blowing out cold air, contact a trusted HVAC technician for assistance.

#2 Little or No Air Is Blowing Out of the Vents

Weak airflow is another issue you need to keep an eye out for. You may feel cool air when you turn your air conditioner on, but it's coming out very weakly, making it impossible to circulate through the room and effectively cool your home. This could be happening for several reasons, from a failing compressor to a problem with the ducts. You won't know for sure until you contact an HVAC technician to come check it out. This professional has the experience and knowledge to figure it out.

#3 You Hear Loud Noises

Just like any other machine, an odd noise is never a good sign. If you hear grinding, clanking, squealing, or scraping noise while the AC is on, a problem with a belt moving out of place may be to blame. Contact an HVAC expert as soon as possible to avoid costly damage to other parts or a total breakdown of your machine.

#4 You Smell Something Strange

Just like noises, an odd smell isn't good either. An air conditioner is not supposed to have any particular small when it's running. If you smell anything coming from your HVAC unit, there is a problem. In fact, a strong smell may indicate a burned-out wire inside the unit. On the other hand, a musty smell may indicate there is mold somewhere inside of the unit or the ductwork. Don't let either of these go. It is absolutely important that a professional HVAC technician come to your home and diagnose this problem ASAP. This can cause you and your family to get sick or put you at risk for a house fire.

If you recognize any of the signs above, you need to get quality AC repair in Las Vegas now. Don't wait any longer!
