Is My Phoenix Home AC Unit Expansion Valve On the Fritz?

Phoenix Home AC Unit Expansion ValveWith summer quickly approaching, are you nervous about the state of your Phoenix central AC system? You want to be sure to have it in excellent working order before the hot months set in, or you could be facing even bigger issues. This is especially important for those of us living in Phoenix and its surrounding areas—we use our air conditioners for most months of the year. If your air conditioner isn’t blowing cold air, there may be something wrong with your Phoenix home AC unit expansion valve.

AC Won’t Blow Cold Air

 If your home feels warmer than it should, but your air conditioner is running, it’s likely that it isn’t blowing cold air. There are a number of factors that could be causing this. For example, your unit could be running low on coolant, or there’s perhaps something wrong with either the condenser or compressor in your expansion valve. Whatever the problem may be, your certified technician will be able to get your unit cooling your home again in no time.

AC is Worn Out

 If your air conditioning is worn out, the first thing you should do is take a deep breath. These situations are stressful, but no matter what’s wrong with your unit, an HVAC specialist will know how to fix the problem at hand and restore your Arizona home to the level of comfort you deserve. There are many possible situations that could explain why your Phoenix home AC unit expansion valve isn’t working properly, and we’ll do everything we can to fix it.

Before contacting an HVAC specialist, make sure you haven’t just blown a fuse. Your central air system should be dedicated its own circuit, and your issue may just be that you need to reset the breaker. Also try turning the power off and on! If none of these reset your air conditioning unit to start working again, it’s likely time to contact a Phoenix home air conditioning repair company.

AC Air Pressure Changes

Air pressure from your air conditioner is dependent on a properly function expansion valve. The expansion valve takes pressure from the liquid coolant in the AC unit to change its state from liquid to vapor via the unit’s evaporator. The expansion valve helps the air conditioner cool an environment not by removing heat, but instead by removing pressure.

There are complicated systems of pressure in place within an air conditioning unit that allow it to function. Thus, if the air pressure is low in one component of your unit, it will affect the other unit parts—and the unit will not effectively be able to cool your home. If your AC airflow or air pressure is low, it’s likely time for you to hire a contractor to fix internal problems in your AC unit.

Fix My Phoenix Central AC System

 There are a few things you can do to try and repair a home AC unit yourself, but if there’s something wrong with your expansion valve, it’s time to hire a contractor. You’ll be able to tell that your expansion valve isn’t working properly if your unit isn’t blowing cold air or if the airflow from your unit is low.
