When Should I Replace My 20-Year-Old Air Conditioner?

It is normal for air conditioners to lose efficiency over time. However, it can be hard for the average person to know whether an AC unit needs a simple repair or requires complete replacement altogether. Since the typical air conditioner lifespan is 10-15 years, units that are over 20 years old often exhibit telltale signs of the need for replacement. A look at some of the top signs that it is time to replace your air conditioner can help you make an informed decision for your unit. Your Air Conditioner Frequently Breaks Down One of the first indications that you need to replace your older unit is that your air conditioner frequently breaks down. Air conditioners that receive consistent HVAC maintenance and yearly tune-ups should not experience constant breakdowns during the summer. Some of the most common air conditioner problems occur due to inconsistent maintenance, and a trained technician can also preemptively identify problems before they cause major damage. If you skipped the recommended annual tune-ups, however, your air conditioner lifespan might end up shorter than expected. Your unit can also break down more often due to extreme temperatures or frequent use. For example, individuals who live in notoriously hot...

Steps for Troubleshooting AC Problems

Central AC systems are fairly complicated and have numerous components that could experience an issue and prevent the system from cooling effectively. Various issues could cause the system to run longer than needed, shut off too soon, or even prevent your AC from running at all. Most AC issues will require hiring a technician to diagnose the specific source of the problem and perform an AC repair service, but there are also issues that you may be able to easily overcome on your own. With that in mind, here are some steps for troubleshooting your AC system. These steps may help you to diagnose the problem or at least rule out certain issues. Make Sure the System Didn’t Trip the Circuit Breaker If you ever find that your AC won’t turn on when the thermostat calls for cooling, you should first check your main electrical panel to make sure the circuit breaker that controls your HVAC system isn’t tripped. If the circuit breaker is tripped, switch your HVAC system off at the thermostat before resetting the circuit breaker. If not, the system could immediately overload the circuit and cause the breaker to trip again. If the breaker does trip again...

Can You Service Your AC Yourself?

In the heat of summer, a well-functioning AC system is critical for maintaining a comfortable indoor environment. When it comes to servicing your air conditioner, is it possible to do it yourself? Unfortunately, the answer is both yes and no. While there are several tasks that you can perform yourself, some aspects of AC maintenance are best left to professionals. Here is an overview of which tasks you can tackle independently and when it’s best to call in the experts. Cleaning and Replacing Filters One of the most critical aspects of air conditioner maintenance is regularly cleaning or replacing the filters. Dirty filters restrict airflow and can significantly decrease the efficiency of your unit. Of course, you can and should perform this task regularly (every 30-90 days, generally speaking), but an HVAC technician will also do this during a routine maintenance visit. Cleaning the Condenser Coils Over time, plenty of dust and debris can accumulate on the outdoor condenser coils of your AC unit. All this dirt and debris can reduce the efficiency of your system. Cleaning the coils is a task you can handle yourself, but it requires caution. An HVAC professional can also perform this task to save...

Is It Possible to Actually Cool a Home With a Swamp Cooler?

Whether you already have a swamp cooler in your San Antonio, TX home or you’re thinking about putting one in, it’s important to understand how they work. While air conditioners, heat pumps, and ductless mini-splits dramatically lower indoor temperatures, swamp coolers only provide a limited amount of cooling. Read on to find out more about the drawbacks and limitations of these units. Humidity Is a Major Factor in a Swamp Cooler’s Cooling Abilities Also known as an evaporative cooler, a swamp cooler uses heat energy from the indoor air to evaporate water. Functioning much like the cooling system that your body uses when temperatures rise, swamp coolers offer a low-cost alternative to conventional air conditioning in moderate climates. When you sweat, heat energy from your skin causes your sweat to evaporate, thereby leaving you feeling a bit cooler. In a like manner, an evaporative cooler uses indoor heat to evaporate indoor moisture. Many swamp coolers work well in temperatures as high as 95 degrees Fahrenheit, but they aren’t much use when the weather becomes significantly hotter. This is especially true during times of high humidity. If there’s already excess moisture in the air when you turn your swamp cooler on,...

Why an Air Filtration System Is Well-Worth the Investment

Like many homeowners, you may think that regularly changing your HVAC air filter is enough to keep your indoor air quality (IAQ) consistently high. Unfortunately, this component is largely intended to protect the health of your heating and cooling equipment. If you want clean indoor air, better rest, fewer allergy symptoms, and superior sleep, you should install an air filtration system in your San Antonio, TX home. Read on to find out why whole-house air filtration is definitely worth the investment. Whole-House Air Filtration Picks up Particulates That HVAC Air Filters Do Not Standard HVAC air filters pick up dirt, dust, dander, and other large-sized particulates. These units are designed and installed by HVAC manufacturers to prevent this debris from coating the sensitive, interior components of their equipment. Although standard HVAC air filters provide limited health benefits, there are many allergens and other contaminants that can flow right through them, including: Volatile organic compounds (VOCs) Mold Bacteria Viruses While you can certainly upgrade the filters in your HVAC system, even filters that have significantly higher maximum efficiency reporting value (MERV) ratings can leave plenty of contaminants behind. Worse still, HVAC air filters with higher MERV ratings can compromise airflow and...

What Can Cause a Furnace Pressure Switch to Fail?

The pressure switch in a gas furnace is an important safety mechanism that ensures the furnace is drafting correctly. If the furnace doesn’t draft properly, it leads to dangerous combustion fumes being trapped inside the combustion chamber and heat exchanger instead of being vented outside. This can cause carbon monoxide to leak into your home. The fumes can also cause a delay before the furnace ignites, producing a small explosion or starving the flames of oxygen so that they escape or “roll out” of the combustion chamber. The pressure switch on your furnace can fail due to various issues. The pressure switch itself can sometimes wear out and fail to activate, but more commonly, it will stop working due to some other problem with the furnace. If the pressure switch ever fails, it will prevent the furnace from being able to start. Let’s now take a closer look at how the pressure switch works and what can cause it to fail. How a Furnace Pressure Switch Works A pressure switch is like any other switch; it makes a connection to allow electricity to flow across it. The pressure switch is activated or closed by the furnace’s inducer fan, which then...

Is Refrigerant Used in Heat Pumps?

Heat pumps are becoming more common in our area for a few reasons. First, they’re efficient, and second, they can be used as both air conditioners and heaters. If you get one installed at your place in San Antonio, you’ll be able to use it every month of the year, if necessary. Heat pumps can do such a great job at keeping homes comfortable because they rely on a substance called refrigerant. What Exactly Is Refrigerant? Refrigerant is a substance that can be found in various forms. In appliances, such as refrigerators, air conditioners, and heat pumps, it can be either in a gas or a liquid form. As it transitions between those two states of matter, it can absorb or give off heat. Over a hundred years ago, scientists and engineers first figured out how to use refrigerant to cool areas. It took awhile for this idea to become a practical one, and obviously, the industry has come a long way since the early days. Now, we can use refrigerant safely and effectively. The Heating Process There are two basic types of heat pumps, and they are air-source pumps and ground-source pumps. Air-source heat pumps get their heat from...
