Problems Caused By A Faulty AC Expansion Valve And How An Air Conditioning Service Can Help | Katy, TX
When your air conditioner’s expansion valve malfunctions, you can experience many problems that greatly reduce comfort and efficiency in your Katy, TX home. From causing erratic temperature swings to reducing efficiency, these issues will only worsen with time if the faulty expansion valve isn’t properly addressed. When your expansion valve isn’t working properly, it’s important to contact an air conditioning service professional as soon as possible to diagnose the issue and take steps to correct it. This article will provide an overview of common issues caused by a malfunctioning expansion valve to help you better understand the importance of prompt repairs.
Leaking Refrigerant
One of the most common problems caused by a malfunctioning expansion valve is leaks in the refrigerant line. A faulty expansion valve can leak refrigerant due to excessive pressure in the system or loose connections between parts inside the unit itself. This will lead to an immediate decrease in cooling power and other problems such as increased humidity and poor air quality. Leaking refrigerant can also cause serious health issues and damage property if not addressed quickly enough. Therefore, when you notice a leak or problems related to the refrigerant, you should immediately contact an air conditioning service professional in Katy, TX to fix it before any permanent damage is done.
Noisy Operation
If your AC unit starts making strange noises when it runs, this could also be due to a faulty expansion valve. Too much pressure in the system due to a defective part or improper installation can increase noise levels from your AC unit when running. The sound may be a low humming or buzzing noise, and it can also be accompanied by rattling or banging noises. An AC professional can inspect the system and determine if the issue is due to a faulty expansion valve or something else, such as worn-out parts. If the issue is related to a malfunctioning expansion valve, they can repair or replace it and restore your AC’s normal operation.
Poor Cooling Capacity
A malfunctioning or blocked expansion valve will reduce your air conditioner’s cooling capacity, resulting in rooms that are too warm for comfort. The reduced refrigerant flow prevents the AC from achieving its desired temperature setting, leading to poor cooling performance. In addition, reduced cooling capacity can cause an increase in electricity bills due to the AC running for extended periods. A professional air conditioning service technician can inspect the system and determine if a blocked expansion valve limits the cooling capacity.
Inadequate Air Flow
When an AC expansion valve fails, it will typically cause inadequate airflow due to decreased pressure across the system. Some signs of inadequate airflow include weak air coming from the vents, decreased cooling efficiency, and inconsistent temperatures across different rooms. Further, poor or insufficient air flow can sometimes damage engine engines due to heat overloads. Thus, an AC expansion valve must be working correctly to get proper performance from one’s AC system. You should contact a professional air conditioning service technician if you suspect inadequate airflow due to a malfunctioning expansion valve. Otherwise, without correct air conditioning service and attention to detail, what started as just uncomfortable temperatures can quickly turn into a much more costly problem.
Compressor Shutoff
A malfunctioning expansion valve can sometimes cause the compressor to shut off unexpectedly. This can be caused by too little or too much refrigerant flow due to an incorrect expansion valve setting or a faulty part. The compressor is the heart of any air conditioning system; without it, an AC unit can’t cool. When the compressor shuts off, it can cause an increase in humidity and temperatures in your home. You should have a professional air conditioning service inspect the system if you suspect the compressor is not functioning correctly.
Frost on Evaporator Coils
When an air conditioning expansion valve fails, it can cause frost on the evaporator coils. This is due to a clogged, out-of-position, or failed expansion valve and poor airflow. If the clog or obstruction of the expansion valve does not allow any hot refrigerant to enter the evaporator coils, then the atmosphere around them will begin to freeze. If left unchecked, this can cause ice build-up, affecting system performance and ultimately leading to costly repairs for homeowners. Therefore, calling a professional air conditioning service technician to inspect your expansion valve is the best way to avoid this issue. Sometimes, the issue can be resolved with simple cleaning or adjustment; other times, the faulty expansion valve may need to be replaced.
High-Temperature Error Codes
Since an expansion valve is responsible for keeping the pressure and temperature of the refrigerant in balance, a malfunctioning valve can cause an AC unit to display high-temperature error codes. These codes indicate that the system is operating at too high of a temperature, resulting in an inefficient cooling process. The only way to correct this issue is to have the expansion valve inspected and either repaired or replaced. A professional air conditioning service technician in Katy, TX can diagnose the issue and help you get your AC unit back up and running efficiently.
Don’t Wait Until It’s Too Late
Faulty expansion valves can often go undetected until major problems occur, but regular maintenance checks are essential for ensuring everything works like it should be working efficiently all year round! If you suspect issues with your AC expansion valve, don’t wait until it’s too late – contact an experienced professional air conditioning service technician to get the job done right and restore your system to its peak performance.
