Subtle Signs That Your AC Might Need Repairs

August 20, 2022

You don’t want to wait until your AC breaks down to realize that it needs repairs. Fortunately, a central AC can give off certain warning signs that it’s malfunctioning, some of which are obvious: extremely short cycles, for instance, or extremely long ones. Here are some of the less obvious signs. Low Air Pressure Maybe the air isn’t coming out so forcefully from your supply vents; you can usually tell just by putting your hand in front of them. This can be caused by a number of things, such as a clogged filter or a dirt-covered evaporator coil, but whatever the issue is, your system may have trouble reaching the set thermostat tempature like it’s supposed to, Which can result in poor energy efficiency. Continuous Noises It’s normal to hear some clicking noises at start-up, but an AC shouldn’t emit any noise during operation. For example, squealing sounds may indicate a bad fan belt while banging and rattling may point to a loose component. A gurgling sound is a sign of a leak in your refrigerant line, which will require immediate attention because refrigerant is a toxic chemical. Many unusual sounds will come from the compressor, the outdoor unit, so...

Five Common Reasons Why My AC Isn’t Working Properly

August 10, 2020

With high temperatures regularly exceeding 100 degrees Fahrenheit throughout the Guadalupe Valley and South Central Texas this summer, you turn to your AC unit for relief. If the air conditioner isn’t working properly, your home could be sweltering hot and unbearably humid. Read on to learn about five common reasons why your cooling system isn’t working properly. 1. Dirty HVAC Filter Dirty air filters are a leading cause of AC and indoor comfort problems. The air filter is located in a small compartment within the indoor unit of your air conditioner. Slide it out and check it. If it’s dirty, replace it. At GVEC Home, we highly recommend checking the air filter monthly regardless of its rating. Admittedly, depending on filter type and the operating environment, some filters can continue working effectively between three and six months. 2. Clogged Condensate Line The humidity condensed from the outside air processed by your AC collects in the AC drain pan and leaves through the condensate line. The pipe can get clogged with algae and other assorted muck. Once every three months, we recommend that the air conditioner be turned off and a solution of vinegar and water poured down the drain to...

Why Is My AC Freezing Up?

June 10, 2020

It can be pretty stressful to come home on a hot day and find your air conditioning unit frozen over. There are a few common reasons why this occurs. Here are some some of the issues you can watch for that may lead to freezing over. AC Airflow Problem The condenser coil in your AC unit needs proper airflow or else it can freeze over. The most common reason airflow becomes restricted or blocked is because the air filter is dirty. Manufacturers recommend changing the air filter anywhere between every one to every six months depending on the filter type, size and materials used. However, at GVEC Home we recommend checking your air filter monthly and replacing or cleaning at least every 3 months. Air Conditioner Refrigerant Leak A leak in your refrigerant lines can lead to reduced pressure. This results in the refrigerant not being able to absorb heat, which leads to the condenser coil freezing over. You will need to contact a professional HVAC technician like those at GVEC Home to solve this problem. If you have an AC system made before 2010 and it’s leaking, you will likely need to replace the entire system because it probably...

How to Fix an AC That Won’t Turn Off

April 20, 2019

Usually, having an AC that runs is a good thing. However, when it never turns off, you can end up with a freezing cold home and excessive utility bills. If your AC unit will not stop running, then follow these tips to address the issue. Look at Your Thermostat The very first thing you should do is take a look at the thermostat. The problem might be as simple as a button that was accidentally pressed. To see if this is the issue, put your thermostat at a temperature above the current room temperature. Wait a moment to see if the system switches off. Check Your Fan Limit Switch This is another thing to consider before you assume your AC unit is broken. Most AC units will have a fan limit switch by the blower that is meant to let you run the fan without having to mess with the thermostat. Switch the fan limit to “auto” so it is not manually overriding the thermostat and continuing to blow all the time. Clean Your Condenser Sometimes, the problem is that your condenser is too dirty to disperse heat. Therefore, the AC runs without accomplishing anything. Cleaning the coils can be...
