There’s nothing quite like the cool relief our air conditioners bring us on hot summer days. After running errands, playing with the kids outside or taking the dog for a walk, we expect to open the door and enter a nice, cool atmosphere. This is why it can come as quite a shock when you step through your door only to find that your house is warm. After some investigating, you may realize that warm air, and not a cool blast, is blowing out of the vents throughout your home.

Unfortunately, there is no easy answer as to why your unit might start blowing warm air. While some of these issues warrant professional help, there are certain steps some homeowners may feel comfortable doing on their own, especially those who are familiar with how HVAC systems work. Before we dive into the more serious issues, let’s touch on those smaller problems … Read Full Post »

Why Does My Air Conditioner Smell Musty?

When we turn on our air conditioners, we expect our homes to become cool and comfortable. In some unfortunate situations, however, homeowners turn on the AC, only to detect an unpleasant odor. If your air conditioner smells musty, you’re probably trying to get to the bottom of the problem and figure out what you can do to fix it.

The most common culprit of an air conditioner that smells less than fresh is the presence of mold somewhere in the system. The other possibility is that your AC unit’s coils have started to corrode. Either way, your air conditioner has likely experienced a buildup of moisture, and the warning sign that that this may be the case is a bad smell.

Not all musty smells coming from your vents start in your air conditioner, however. Identifying the cause of this problem is the first step to resolving it. There are a couple … Read Full Post »

No Cold Air From AC: What Can You Do?

April 30, 2020. Posted by Tom Riggs in Air Conditioning & Heating • San Antonio

When you enter your home after spending time outside on a hot day, there’s nothing quite like the gust of cool air coming from your air conditioning vents. That’s why if you find yourself in a situation where you have no cold air coming from your AC, panic can quickly start to set in. Most likely, you switch into high gear, trying to determine what went wrong and what you can do to get your air conditioner working normally again.

There are several things that could be preventing your AC from blowing cold air, including a problem with your thermostat, dirty filters, a clogged condensate line, a blocked compressor or dirty coils. Your air conditioner is a machine with many parts that need to work together. If any one of these parts isn’t working correctly, you wind up with a system that doesn’t cool anything down or maybe doesn’t blow air … Read Full Post »

Water Leaking From AC Unit: Should I Be Worried?

March 20, 2020. Posted by Tom Riggs in Air Conditioning & Heating • Austin

Finding a pool of water near your air conditioner can be alarming. You may ask yourself: Why is this happening? Is this liquid water, or could it be refrigerant? While being in this situation can be alarming, you should know that it’s not uncommon to find moisture near your AC unit, and this may not actually be a bad thing. To determine whether your water leak is serious, it’s helpful to understand how air conditioning systems work.

Air conditioners use refrigerants to cool down the air that flows through your home. These systems operate thanks to a handy piece of physics: When a liquid turns into a gas, it absorbs heat. So, with a substance that changes from a liquid to a gas at a relatively low temperature, as is the case with refrigerants, you can harness that heat-absorption power to cool down a home on a hot summer day.

Why Does My Air Conditioner Keep Running When Turned Off?

You are pleasantly surprised that after a heatwave, the weather outside is nearly perfect. So, you turn off your air conditioner and head outside to take advantage of a beautiful afternoon. However, after coming back in a few hours later, you realize that your air conditioner is still running, even though you turned it off. While this is arguably a better situation than having an air conditioner that won’t turn on, it’s still wasting energy and money. So, what can you do to turn off your air conditioner? Or is this a problem that requires the help of a professional?

Electrical issues are the most common cause of an AC unit that won’t stop running and these types of problems typically need to be addressed by a licensed heating and cooling specialist. However, before contacting a professional, you can check your fan to make sure this isn’t the problem.

My Furnace Won’t Ignite: What Should I Do?

October 11, 2019. Posted by Tom Riggs in Air Conditioning & Heating • Corpus Christi

You are ready to curl up to enjoy a movie on the couch when you realize that it is still freezing in your home despite turning on your furnace. After some quick investigating, you come to the conclusion that your furnace won’t ignite. Sadly, there is not an easy answer to why this might be happening.

Any of the following problems could be responsible for your furnace not working properly:

Clogged filters
Loose wiring
Low gas supply
Malfunctioning thermostat
Your pilot light is out
The furnace is old or broken

Some of these problems will be easier fixes, while others will require professional help. When your pilot light goes out, your furnace won’t ignite and heat your home. Sometimes, this is the only problem that you need to fix, and things will go back to normal. Other times, the pilot light is still on, but other parts of the furnace could be malfunctioning. Or, it could be that … Read Full Post »

Why Is My Electric Bill So High?

October 9, 2019. Posted by Tom Riggs in Air Conditioning & Heating • San Antonio

No homeowner wants to be hit with a surprisingly large utility bill. With so many other things on your plate, it can be hard to determine exactly why your energy costs might have skyrocketed suddenly, or why your monthly costs have gotten so expensive over time. If you find yourself in the position of asking yourself: Why is my electric bill so high?, you should know that while there are actually a number of factors that could be responsible, the most likely is a problem with your heating and cooling system.

Air Conditioning Or Heating Issues

You may not realize that keeping your home at a comfortable temperature typically accounts for nearly half of your energy use for any given month. Reviewing your billing history is always a good place to start your research if you feel something is amiss. Check your current statement against the same month one year ago. In … Read Full Post »

My Furnace Won’t Stay On: What’s Going On?

September 23, 2019. Posted by Stephen Richardson in Air Conditioning & Heating

You’re freezing, so you get up to turn on the heater to warm things up. You hear your furnace click on and go sit back down, assuming you’ll feel toasty soon. A couple of minutes later, you hear the heat shut off. You repeat this process a few times when you come to terms with the fact that your furnace won’t stay on. So, what’s wrong? And, more importantly, what should you do to get your heat working again?

Your Thermocouple Is Bad

If you have a furnace with a pilot light, then you will have a thermocouple. The job of the thermocouple is to determine whether or not the pilot light is lit. This is a safety device that closes your gas valve when the pilot light goes out so gas doesn’t enter your home. You can check to see if this is your problem by seeing whether or not your … Read Full Post »

What Is EM Heat On A Thermostat?

September 20, 2019. Posted by Tom Riggs in Air Conditioning & Heating • San Antonio

If you take a look at the thermostat that controls your home’s heating and cooling systems, you might notice a switch or button labeled “EM heat.” If you see this, your home probably has a heat pump. The first part of the phrase “EM heat” stands for emergency. The emergency heat setting on your thermostat controls your heating system’s auxiliary heat source, which can be tapped into when outside temperatures drop below a certain threshold—usually anything colder than 35 to 40 degrees Fahrenheit. Now that you understand the answer to the original question—What is EM heat on a thermostat?—let’s learn more about this setting and why it comes on.

When functioning properly, the heating system’s heat pump pushes warm air from inside your home to the outside during hot weather and moves heat to the inside during cold weather. When outdoor temperatures drop into the thirties, however, it can become too … Read Full Post »

Why Is My Furnace Short Cycling?

August 19, 2019. Posted by Tom Riggs in Air Conditioning & Heating • San Antonio

If you turn on your furnace and discover it’s not heating your home properly, you probably realize how much you take your heater for granted. In some cases, it may seem as though your furnace shuts off just about as quickly as it turns back on. If this has ever happened to you, you probably have asked yourself: Why is my furnace short cycling?

Homeowners in this situation can usually blame one (or more of the following) culprits for this issue: a clogged air filter, a dirty flame sensor, an oversized unit or a malfunctioning thermostat.

Clogged Air Filter

When your system’s filters are caked with dust particles, pet hair, pet dander and other debris that make it into your indoor environment, this buildup restricts airflow. The warm air becomes blocked in your furnace, raising its internal temperature. This warm air sends a signal to your system to shut off.

A furnace that turns … Read Full Post »
