Tuesday, July 29th, 2014

Choosing to replace your older heat pump is a big decision. Your heat pump may still be running fairly well, so replacement may seem like an unnecessary expense. But an older system may run into a lot of repair problems overtime, and a sudden breakdown may be far more costly to replace, leaving you without any AC when you need it most.

However, we’ve put together this list of some ways to tell it’s time to bite the bullet and call a professional for heat pump maintenance. There may even be some benefits in it for you!

  • You have owned your system for several years. Check with your manufacturer to find the expected lifespan for your unit. While no two systems are exactly alike, a system that is ten years old has a high risk of breaking down.
  • You have to make frequent repair calls. While some repairs are expected with all AC systems, regular repair needs for your heat pump indicates your system may be too worn out to function properly.
  • You’ve noticed decreased performance or efficiency over the years. In this case, the benefits of new heat pump installation may be too good to pass up.

Benefits of Professional Air Sealing in San Antonio, TX

Tuesday, July 22nd, 2014

You may not have thought of your home as “leaky” before (it’s not a houseboat, after all), but air leaks in any building can lead to a massive amount of energy loss—in fact, enough small leaks in a house that you might think are innocuous can account for as much air loss as if you left the front door wide open! This means high bills and low comfort. If you have a leaky house, you will benefit from professional air sealing in San Antonio, TX that will locate where you are losing heat and then close up all the gaps, cracks, and holes with quality insulation.

You can reach professionals in air sealing in San Antonio, TX with just a phone call:

Cowboys Air Conditioning & Heating has 25 years of experience with home comfort, and we can assist you with insulation repairs and replacements that will create a tight heat seal for your home.

How you will benefit from professional air sealing

The U.S. Department of Energy’s ENERGY STAR program, founded to help homeowners and businesses save money through more efficient energy use, identifies the following benefits of air sealing:

  • Better comfort: During both hot and cold weather, air leaks in a home create uncomfortable temperature shifts. Cold drafts will pour through the insulation gaps, and heat will steal indoors to make a home stuffy.
  • Reduced utility bills: The Department of Energy estimates that poor insulation in a home can waste 20% or more of the energy used to heat or cool the space. And that means 20% more work for a home’s heater and air conditioner, leading to an increase in costs. Think about shaving off a fifth off your utility bills (or more) each year! That’s was professional air sealing can do for you.
  • Improved indoor air quality: Low indoor air quality is a major health concern in the country today. Proper air sealing prevents the intrusion of dust, dirt, pollen, and increases in humidity that will negatively affect the health of people in your household.
  • Longer life for your home: Warm air that enters a home through the floor, walls, and attic can lead to condensation and water moisture—and that creates a fertile area for the growth of destructive mold, wood rot, and mildew. This will cause both short-term and long-term problems for your home. The material of your house will remain stronger for a longer period of time with air sealing keeping out the moist air.

The first step for improved air sealing in San Antonio, TX is to call the indoor air quality experts at Cowboys Air Conditioning & Heating. They will find where your home is “leaking” and then install the right insulation in the proper spots so that you will have a comfortable and energy-efficient environment.

How Do UV Germicidal Lights Work?

Friday, July 11th, 2014

Sunlight has long been known to kill problematic organisms such as mold and mildew. But there are several different types of light that emit from the sun, and each type of ray has its own effect on organisms. UV light, also known as ultraviolet light, is actually a type of electromagnetic radiation that can help eliminate germs entirely without the side effects of harsh chemical disinfectants. So how can UV germicidal lights help your air conditioner in San Antonio? It’s in the nature of how the lights work.

What Is UV Germicidal Light?

As mentioned above, UV light is electromagnetic radiation from the sun; the most harmful UV rays are screened out by the Earth’s atmosphere. UV light is divided into 3 classifications: UV-A, UV-B and UV-C. Each can damage organisms, but it is the UV-C light that is classified as “germicidal”.

How Do UV Germicidal Lights Work?

UV-C light can destroy a great number of microorganisms, including viruses, bacteria, mold spores and allergens. It irrevocably damages the organism’s DNA. The damage caused by the UV-C light destroys the organism’s ability to both replicate and create life-sustaining proteins. The end result is that the organism can no longer reproduce or survive.

Benefits of UV Germicidal Lights 

  • Kills germs
  • Helps eliminate odors
  • Stops mold and bacteria growth
  • Destroys volatile organic compounds
  • Generates negative hydroxyl ions


UV germicidal lights can be placed different areas of your air conditioning system:

  • Over evaporator coils
  • Inside air ducts

When placed over the evaporator coils in your system, UV germicidal lights eliminate growths like mold, mildew, algae and gel formations. In your ductwork, microbes like bacteria, viruses and allergens are destroyed before they can enter through the vents.

Ready to Shine Some Light on Germs?

UV germicidal lights kill over 99% of micro-organisms. If you have concerns about germs, mold growth, bacteria and allergens, it may be time to consider what a UV germicidal light can do for your home.

Call Cowboys Air Conditioning & Heating today and schedule and appointment to discuss having UV germicidal lights in your San Antonio home.
