Top Reasons Your AC System Is Not Blowing Cold Air

You are already quite aware that your Las Vegas, or Henderson Nevada home air conditioning system represents one of the largest home appliance investments that you will ever make.

In this post, we are going to discuss some reasons why your air conditioning system is not blowing cold air, and offer you some ideas on keeping your  system healthy and protecting your investment!

From simple dirty filters that need to be replaced, to the more technical as well as electrical issues, there are several things that may cause your air conditioning system not to be blowing the cold air you are accustomed to. Let’s begin by exploring some of those issues and hopefully this will educate our valued homeowners, and shed some light on the importance of keeping your air conditioner in top form with the added value of an HVAC maintenance plan from the team of dedicated HVAC professionals here at Legacy Air.

Faulty Capacitors That Can Cause Your System to Appear to Be Done For

There are many calls made to air conditioner repair companies each summer in which the person calling has already determined their air conditioner has died, and they need some information on its replacement. That is not always the case.

The compressor in your air conditioning system is basically a heart. That heart needs to be supplied with a jolt of power in its starting procedure, and a subsequent jolt to keep running. This jolt of power comes from the capacitor located somewhere close to the compressor, and connected to it electrically.

The capacitor stores energy, much like a rechargeable battery, and when it is time for the compressor to start and run, the capacitor handles this request. There are two main enemies of your air conditioner’s capacitor. Heat, and power surges. Two things that are in ample supply in the summer. Heat of course from those long hot days, and power surges from things like lightning strikes in those frightening summer thunderstorms.

When either of these claims another capacitor, it also accompanies another air conditioner repair. The worried homeowner breathes a sigh of relief when having to pay for the compressors’ capacitor instead of a new system!

By far, the simplest way to keep this scenario at bay during those hot summer Las Vegas, and Henderson days is by keeping an eye on your systems overall health. This is easily and affordably accomplished when you implement an HVAC maintenance program from the team at Legacy Air.

A Dirty Air Filter Can Block Your Cold Air Flow!

Another issue facing your air conditioner during its peak season of operation is brought on by dirty air filters. The air filter in your system is already designed to restrict the air flow simply by its presence. Add to that, a totally blocked filter media from dust, dirt, and other foreign debris and this will leave your nice cool air flow blocked from cooling you and your rooms, and it will create further problems.

Blocked or dirty air filters will cause your unit to cool unevenly, allowing some rooms to be too cold while others seem to be not receiving any cold air at all. Blocked filters can trap pockets of cold air in and around your air conditioner coils causing icing issues that will eventually lead to water damage from the ice.

With all the talk in this past year about the quality of the indoor air that we breathe, wouldn’t it seem to be in your best interest to not only change your air filter monthly, but consider upgrading to a better filter choice! Air filter replacements are a part of any HVAC maintenance program, but it is also something that you as a homeowner can make sure happens every month, again protecting your investment.

Air filter upgrades and replacements are another essential aspect of your HVAC maintenance agreement from the team of dedicated professionals here at Legacy Air, in Las Vegas and Henderson, Nevada.

Thermostat and Cooling Switch Issues

The thermostat of your system is essentially the user interface between you and your air conditioner.

If your thermostat happens to be one of the older ‘analog’ types, it can be prone to either being out of calibration or basic malfunctions as it is just like any other device in your home and could be subject to failure at any given moment. Having a professional technician to come and properly diagnose any thermostat malfunctions tends to be one of the rather simpler solutions when air conditioners begin blowing less cold air. Sometimes, it can be as simple as the cooling switch being inadvertently switched ‘off.’

Your thermostat is also much like the air filter in that now may be a good time to consider an upgrade! The newer and more efficient digital thermostats can implement the latest thermostat technology to make your older air conditioning system perform like new!

Keep Those Condensing Coils Clean!

An ‘Achilles Heel’ for your air conditioner is the large condensing coils found on the outdoor portion of your air conditioner. The condenser coils is where the heat from your home is eliminated through a fan forcing the heat off of the coils as the refrigerant attracts the heat, transfers it through copper tubing to the condenser, and as it weaves its way through that coil, the fan rushes across the surface to dissipate the heat.

It is paramount that the condensing coil be keep flushed out with water and those tiny aluminum cooling fins around it, be kept as straight as passible. A dirty coil, and bent fins can reduce your systems cooling capacity causing it to, as you guessed it, blow less cold air! Both the condition of the condenser coil, and the condensing fan motor should be serviced at least semi-annually for maximum cooling capacity from your system on those days that it is needed the most.

These things that are listed here in this post are some of the more frequent situations where your air conditioner will tell you that there is a problem by blowing less cold air. This is where a residential HVAC maintenance plan from the team of professionals here at Legacy Air can literally pay for itself.

When you implement a maintenance agreement, our professional service technicians will check for all of these issues, and more. This can alert you to the need of replacing small inexpensive parts before they catastrophically fail leading to your displeasure as well as an expensive air conditioner repair invoice.
