What Happens If My AC/Heating System Is Too Big for My House?

June 23, 2021

The weather in La Vernia, TX, and surrounding areas often goes from one extreme to another. You’ll need an efficient and effective air conditioning and heating system to maintain consistent indoor temperatures. If your HVAC system is too big or has too much capacity, this could lead to several issues that affect your comfort and wallet. Poor Humidity Control An air conditioning system that’s too big for your home may perform short cycling. This happens when the air conditioner runs at full power for a minute or two. It reaches the temperature setting on the thermostat quickly, then turns off. However, it won’t remove enough humidity from your house during this short cycle time. As a result, your residence won’t feel as comfortable as it would with a right-sized system. High humidity levels can also worsen allergy and asthma symptoms. High Utility Bills Cooling and heating your home make up roughly 50% of your monthly energy costs. If your system is the wrong size for your home, it could operate less efficiently and cost you even more. When the unit has too much capacity for your home, it may use more power than a correctly sized system. This can result...

3 Reasons Why Regular Maintenance Is Good for Your AC/Heating System

June 9, 2021

Lack of maintenance can cause major issues for AC/Heating systems. You may have to deal with a variety of problems if you neglect your regular tune-up. Always reaching out to a local HVAC company to service your system twice a year is an excellent way for you to stay proactive and avoid many of these issues. Here are a few of the most likely things that can happen if you fail to keep your system well maintained. 1. Costly Breakdowns Over time, a heating and cooling system may eventually break down due to a lack of maintenance. These repairs can often be expensive and create a lot of stress. The easiest way to reduce the need for repair work is to schedule routine maintenance services. An HVAC technician will inspect your entire system and make any adjustments to ensure everything is working at an optimal level. 2. Reduced Lifespan Another disadvantage of poor maintenance is that it can reduce the useful life of your system. The average lifespan of most HVAC systems is around 15 years, but this expectation can be cut much shorter if you fail to keep the equipment professionally maintained. The investment in maintenance services is well...

What Is A VRF AC/Heating System?

May 26, 2021

The hot summers in South Central Texas, mean that you need an effective cooling system for optimal indoor comfort. When it’s time to replace an aging air conditioning and heating system, you’ll likely encounter many options in the course of researching various products. One of these you may encounter is the variable refrigerant flow (VRF) AC/heating system. GVEC does sell these systems—mostly to commercial customers—but there is a residential version known as the mini-split. In this entry, we’ll be explaining a little about VRF systems for commercial use. What VRF Means HVAC systems based on VRF technology use a chemical refrigerant to transfer heat from one location to another. These ductless systems are extremely complicated, but amount to a highly enhanced version of the mini-split systems mentioned above. VRF systems include heat pumps and smaller mini-split units. How VRF AC and Heating Systems Work VRF systems use variable motor speeds and varying amounts of refrigerant flow to transfer heat. They do this with an inverter compressor. An inverter compressor doesn’t have to be 100% on or off. It can function at 30%, 60%, or any other power level. This allows it to heat or cool a building with more efficiency...

What Is an Electronic Air Filter? Do I Need One?

May 19, 2021

Spring is in the air, and, unfortunately, that means pollen and allergens are as well. Keeping these particulates out of your home is a challenge in the subtropical climate of South Central Texas. Electronic air filters offer one possible solution for helping filter allergens from the air. Although we don’t sell these filters, we think it important for readers to understand their options regarding home air filtration. We do, however, offer a number of UV-light based home air filtration systems, which we’ll mention briefly near the conclusion of this blog. What Is an Electronic Air Filter? The most common type of electronic air filter is known as an electrostatic air filter. These complex systems work by creating an electrostatic charge that ionizes the air passing through the system. The ionization process causes the particles in the airflow to become positively charged. While passing through the system, the negatively charged filtration plates trap the positively charged particles. How Effective Are Electronic Air Filters? Electronic air filters can be efficient at trapping larger particles and finer particles that pass through the system. Mid-sized particles may still pass through, however, as these particulates don’t always receive a charge. Also, the filters will not...

What is Indoor Air Quality, and Should I Worry About It?

April 19, 2021

Many people in this day and age spend quite a bit of their time indoors. In a typical home, air can be two to five times more polluted than the outdoor air. Breathing polluted air all day can have serious impacts on your health, comfort, and quality of life. Here’s what you need to know about indoor air quality and why you might be concerned about your home’s air quality. What Air Quality Means Air quality refers to the cleanliness of the indoor air and how it impacts your health. When a building or home is tightly sealed, pollutants stick around. Circulating the same air all day means you keep breathing those pollutants. The elderly, babies, and people with chronic breathing disorders are especially susceptible to the effects of poor indoor air quality. Pollutants That May Be in Your Home’s Air Every home has indoor air pollutants. Some of the most common pollutants that could be in your home include formaldehyde, benzene, and other volatile organic compounds. They may come from pressed wood products, dry-cleaned clothing, sealants, adhesives, paints, and pesticides. Your home may also have carbon monoxide and nitrogen dioxide. These come from the combustion process. Tobacco smoke, radon,...

What’s the Proper Indoor Humidity Level for My Home?

April 5, 2021

You have probably heard about how low humidity can impact your health, but too much humidity may also affect it. It is important to monitor humidity levels to avoid health issues. Controlling humidity levels also helps your HVAC unit run more efficiently. Why Humidity Level Matters Low and high humidity both impact health and homes, but in different ways. High humidity in your home plus high temperatures could interfere with the body’s natural way to cool itself. The body sweats to lower its temperature, and if the body can’t cool off, it may cause a heat stroke. Low humidity commonly causes dry throats, chapped lips, dry and itchy skin, cracked wood, and static electricity. High humidity increases the chance of mold, which often worsens allergy symptoms, and too much moisture may damage wood and other fixtures. Measuring Humidity Level in Your Home There are methods you can use to find the humidity level in your home. Place a few ice cubes in water in a clear glass in any room but the kitchen, and check them in four minutes. Condensation on the glass commonly indicates high humidity levels, and no condensation indicates low humidity. If the home has balanced humidity,...

Should I Add a Ventilator to My AC/Heating System?

February 20, 2021

If you’ve noticed that the air in your South Central Texas home is often stale, sutffy or smelly, you might be wondering if a ventilator would help. Home ventilation is essential for indoor air quality, comfort and health. Consider these pros and cons of using a ventilation unit in your home. Indoor Air Quality Adding active or mechanical ventilation to your home could improve your indoor air quality. This is important if your household includes anyone with allergies, asthma or another respiratory disorder. Ventilators exhaust the stale, particle-filled air from your home and bring in fresh air from the outdoors. The fresh air is filtered before it reaches your living spaces. Is Natural Ventilation Enough? Small cracks and holes in homes can provide some level of natural ventilation. However, these are the same opening you want to seal to help your energy efficiency. Natural ventilation in a home is also often unpredictable and beyond a homeowners’ control, especially during extreme outdoor temperatures and weather. Utility Bills If you install balanced, exhaust or supply ventilators, your heating and cooling costs could increase. Installing an energy or heat-recovery ventilator will lower your heating expenses, but these systems cost more to install. In...

Why Do I Have Mold in My Air Ducts?

February 10, 2021

Having mold in your air ducts isn’t a rare occurrence. There are multiple ways this can happen to you. Signs of Mold One sign of mold in your air ducts is a musty smell in your house after your HVAC system comes on. You may see visible mold in your air conditioner’s drip pan. Another sign is if your family develops symptoms like nausea, itchy eyes and headaches. Oversized AC Unit Having an AC/heating system that is too big for your home can also result in mold in your air ducts. An oversized AC unit may cool your home too quickly, which means it doesn’t have time to dehumidify your home. This can lead to moisture building up in the air ducts, which creates an ideal place for mold to grow. GVEC of Gonzales, TX, installs HVAC systems. We always make sure we install the right size unit for your home. Temperature Set Too Low If you set your temperature too low when cooling your home, mold can grow around the vents. The vents are where warm and cool air meet, which can cause condensation on surfaces. If the surfaces don’t get the chance to dry out, mold will grow....
