Do I need a Dehumidifier?

Humid summers are typical in the midwest. “It’s not the heat but the humidity!” is something you’ll hear often enough. When humidity levels reach 90% or even 100%, it can turn a pleasant picnic into a sweaty mess. We know what high humidity can do outdoors, but how does high humidity affect your home on the inside? Do I need a dehumidifier?



Mold and Mildew

High humidity makes for an ideal atmosphere for mold and mildew formation. Mold can not only cause mild to serious health issues like asthma and allergic reactions but left unchecked, mold can cause structural weakening of walls and ceilings. 

Paint and Wallpaper

 If you see peeling wallpaper and chipping paint, humidity may be the culprit. Exterior walls are especially susceptible to changing humidity levels. 

Furniture and Floors

 Wood floors and furniture can be affected by changing humidity levels. Stained furniture and buckled flooring can point to prolonged high moisture content. Expensive damage to tight-fitting wood frames around windows and doors can also occur in humid conditions. 

Walls & Brickwork

 Humidity can wreak havoc anywhere in your home that contains a moisture or vapor barrier. Drastic changes in moisture levels can cause cracking along drywall and brickwork inside the home, sometimes causing costly repairs. 

What Can I Do?

Preventing high humidity levels inside your home can be as simple as utilizing fans in moisture-prone areas like bathrooms, laundry rooms, and the kitchen. Maintaining a relatively consistent air temperature inside your home can also contribute to lower humidity levels. Also checking your crawl space and/or attic for any moisture buildup or leaks is important for humidity control.

Lastly, tools like in-home air quality monitors and smart thermostats are great ways to understand the indoor humidity levels in your home throughout the year. The Mayo Clinic recommends humidity levels between 30% and 50%. Whole-home dehumidifiers and humidifiers can keep your home at optimum humidity levels all year long.

How to Improve Your Home’s Air Quality to Keep Your HVAC System Clean

Many homeowners aren’t aware of how indoor air quality affects an HVAC system, but there’s a direct relationship between the cleanliness of indoor air to how long and efficiently a cooling and heating system will run. Dust and biological contaminants pose the highest risks for your HVAC system and your family’s health.

Airborne Particulates

All forced-air HVAC systems require air filters that keep the components inside the air handler clean. As with all electronic and mechanical devices, efficiency can be affected by dust accumulation, which can even shorten life spans. Dust covering any component in the air handler has a negative impact.

When dust covers the heat exchange components of an HVAC system, including the air conditioner’s evaporator coil and the furnace’s heat exchanger, efficiency is lost, setting the stage for premature part failure. Repairs caused by too much dust can be expensive.


These are among the smallest particles that have an impact on how indoor air quality affects the HVAC system. They include bacteria, viruses and mold spores that can cover the evaporator coil, reducing efficiency in the same way dust does.

Mold is especially troublesome inside an HVAC system, since the spores can blow throughout your entire home, finding a place to grow wherever sufficient moisture and organic materials are present. Mold causes eventual deterioration of the materials on which it grows.


  • High quality air filter – Selecting a higher efficiency air filter and changing ti when dirty will reduce the amount of dust entering the HVAC system’s air handler and ductwork.
  • UV lights – When mounted in the air handler and ductwork, these lights lower the population of bioaersols by preventing their reproduction, keeping the HVAC components and your home’s air cleaner year-round.
  • Dehumidifier – A central dehumidification system eliminates excessive summer humidity and reduces the potential health hazards mold poses while improving comfort and lowering energy bills.

HOW TO – Keep Your Home with Pets Clean For Better Air Quality

We love our pets. They are members of our family and we love to include them in our everyday activities. It is important to keep your home clean as part of improving your indoor air quality and helping to prevent breathing problems. We’ve provided several easy steps for you, to maintain clean indoor air quality in a home that has pets.

Groom Regularly

Whether it be a dog or cat, grooming regularly is important. While long-haired breeds shed noticeably more amounts of hair, most pets shed at least some of their hair every day. Brushing your pet frequently helps you controls how much of that shed hair ends up on your furniture and carpet.

Regular baths for your pet are also important. Both dogs and cats that are let outside tend to bring dust into the home and contaminate the air, affecting air quality. More frequent baths can help remove the dirt and allergens that cling to pet hair and fur.

Change Your Air Filters

Even if you groom and bathe your pets rather frequently, you will still need to change your air filters every month. While grooming your pet, at least some dirt and dander tends to get released into the air. Furnace filters catch the allergens that are floating in the air.

Your best bet is to use a high-quality air filter that collects even microscopic particles, like pet dander and keep your air clean. If you are unsure about what type of air filter is best for your furnace, feel free to contact one of our knowledgeable service technicians, and we would be happy to help.

Install an Air Purifier

Regardless of how often you bathe or brush your cat or dog, you may notice a distinct pet odor in your home. If you have a cat, the litter box needs to be cleaned every day and you should try to wash your pet’s bedding around once a week. Another great method for cleaning and refreshing the air in your home is to use an air purifier. Whole-house systems are available, and they work with your furnace to clean the air as it circulates and warms. There are even some systems that come with a germicidal fog sanitizing option that disinfects the air.

You may also want to consider installing an energy recovery ventilator. These units work great during the colder winter months when you might not open your windows and allow fresh air into the home. An ERV brings in fresh outdoor air and warms it before circulating the air into your HVAC system. The fresh air smells great and makes your whole house feel clean and deodorized.

Invest in Duct Cleaning

Another crucial step to having cleaner air is to have your HVAC ducts cleaned out around per year. It is common for pets to lay on the heat ducts and enjoy the warm air, which results in hair and dirt getting into the ducts. Even a vacuuming of the area will not sufficiently remove it all. In some situations, hair will actually shoot out of the vents when the furnace kicks on. This is a clear sign that you need to call a professional to sanitize and clean your ducts.

Cleaning your ducts not only keeps the air clean. It also increases the efficiency of the unit. Removing all the pet hair and dirt from the ducts will allow air to move freely. As a result, your furnace won’t have to work as hard, saving you money on your energy bills.

Is a Heat Pump Right For My Home?

warm home

We’re seeing an ever increasing number of inquiries from homeowners about heat pumps. What are heat pumps, and how do they work? Are they right for me? While heat pumps are more commonly utilized in the warmer areas of the country, they are becoming more widespread in all states.

What is a Heat Pump?

Heat pumps are an energy-effective option in contrast to furnaces and air conditioners. They give both heating and cooling utilizing heat transfer and electricity, the characteristic inclination for heat to move from spaces with higher temperatures to those with cooler ones.

In the colder time of year, a coil of tubing loaded up with refrigerant urges thermal energy from the outdoor air. After warming and vaporizing into a gas, it is brought inside to the pump’s inside unit and warms encompassing air that is then fanned all through the home.

Home Heat Pump

In the summer, heat pumps can cool your home by reversing this same cycle. Coils pull thermal energy from within the home to cool the inside and push warm thermal energy outdoors. This cycle utilizes thermal dynamics and eletricity to warm and cool the home, rather than coal, oil or flammable gas.

Heat Pump Benefits

By having one framework that gives heating and cooling you can save money on upfront equipment costs by not having to buy a furnace.

Consolidating the mechanical proficiency with off-peak seasonal electricity rates in the cold weather months implies lower energy costs for heating.

Since heat pumps use power productively instead of consuming non-renewable energy sources, they are for the most part cleaner and environmentally friendly.

Heat Pumps with Secondary Heating Sources

While heat pump innovation is turning out to be increasingly more proficient at heating and cooling, there are still conditions where a furnace or optional heat source will be important. In zones of the U.S. that regularly get beneath 15°F for extended times, it may be valuable to utilize the heat pump with a helper heating arrangement, for example, a traditional gas furnace. Get some information about the most recent high-effectiveness heat pumps and double fuel frameworks accessible for your area of the nation.

With appropriate upkeep and support, a heat pump climate control system that does both heating and cooling can provide a low-cost, high-efficiency and environmentally friendly answer for your heating needs throughout the year.

How Viruses Spread and Why Air Purifiers Can Help

What Air Filtration Systems Can Do To Reduce Virus Particles

Most viruses spread via person-to-person contact, and most often through the air (coughs, sneezes, etc.), according to the CDC. Water vapor attached to the virus particles are carried in small droplets that move in a fine mist. The main symptom of most respiratory viruses is coughing, which just further adds to the chances that the air could be contaminated with virus particles.

One of the main reliable ways to remove these virus particles from the air is to circulate all of the air in a room or enclosed space, and to do this multiple times per hour. This increases the likelihood that a filter can catch the virus particles and remove them from the total volume of the air.

Air Filtration Is Just One Part of Prevention

Air purifiers aren’t the only preventive measure you can take to lower the chances of catching a virus. Keeping distance from someone thought to have a virus is necessary to lower the chances of breathing in virus particles. Also, keeping your hands clean and surfaces clean is an important part of keeping yourself safe from catching a virus. Taking one, or more of these preventive measures can drastically decrease your chances of catching an airborne virus.

Official Preventative Guidelines Given By The CDC

According to the CDC, here are the top seven ways to protect yourself from viruses every day:

  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol.
  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.

The Benefits of Managing Your Home’s Air Quality

how is the air quality in your home

Would you say that you take your home’s air quality seriously enough?  With so much on your plate it’s easy to neglect or flat out forget to take care of your home’s air quality.  Traces of particle allergens, chemical pollutants, mold, harmful bacteria, carbon monoxide and carbon dioxide can be lingering in your home.  It’s actually not very difficult to take the proper steps to ensure that the air quality in your home is both clean and safe for you and your family.  We’ll show you the downside of not monitoring your home’s air quality and the benefits of being proactive with your air quality.  We’ll also show you what you can do in order to make sure the air in your home is as comfortable, healthy, and safe as it it can be.

Poor Air Quality Increases Your Chance of Allergies

A major source of what causes allergies stems from dust and pollen in the air.  Studies show that the effects of dust and pollen are even more prominent in children.  It’s especially important that children four and under breathe clean air.  They have the highest chance of developing asthma because of harmful air pollutants.

Poor Air Quality Can Increase the Chance of Spreading Poisonous Mold in Your Home

If mold is found in the air, it can cause serious illness and even fatalities in some cases.  If ignored, the problem only gets worse and continue to spread.  Being proactive in monitoring and managing your home’s air quality helps to reduce the chances of mold repopulating.

Poor Air Quality Can Cause Expensive Problems

Issues due to poor air quality can become costly over time.  Excess pollen and dust means your HVAC system filters tend to need to be replaced more often.  In some instances, clogged filters made worse by poor air quality can force your HVAC system to overwork because of the dust, which can mean that its lifespan is reduced drastically.

A Solution…?

You may be wondering what you can do to monitor and prevent any of these problem from occurring due to lackluster air quality.  The first step is to get an air quality test.  We recommend an AirAdvice Indoor Air Quality Home Test.  These tests check for and detail any problems your home might have with humidity, heating/cooling, carbon dioxide levels, carbon monoxide, etc.  They only take around 30 minutes and are well worth the price, which is typically very reasonable (~$199).  The report you receive from the test will detail the health, comfort, and safety levels in your home, and provide solutions to improve your environment.  You can always contact us to get tested – Our number is (812) 858-4000 or schedule an appointment here.


How UV-C Lamps Purify Air and Save Money

This month, we’re running a special on UV-C Lamps—both Bryant UV-C Lamps and other brands! We’ve found that many of our customers aren’t aware of the major benefits of using these lamps in your house, so we thought we’d write a quick blog post to explain the most major benefits!

Sterilized Coil Surfaces

We know, we know. This sounds super technical!

While it’s hard to think about the tangible benefits of having sterilized coil surfaces in your A/C unit, you should trust that this makes a HUGE difference in your day-to-day health.


Because the coils in your unit are notorious for accumulating mold, dust, and other bio-contaminants. If you’re not regularly cleaning your coils, you’re likely allowing the germs and allergens from that accumulation to be blown throughout your home. Keeping a UV-C lamp in your system is the easiest and lowest-maintenance way to keep those coils clean!

Maximize Efficiency

While your lungs and your allergies will be thankful that the UV-C lamp is keeping those coils clean, your wallet will thank you for the increased efficiency you’ll also see!

It’s simple. A clean coil is a highly functioning coil! And a unit that is clean and functioning at its best will always save you money.

It’s Simple

Adding one of these lamps to your unit is simple—our experts do it all the time! And, even better, they’re affordable! This month, we’re offering $25 off when you buy one from us.

How We Use Cold Plasma to Blast Germs in Your Home

You may know that air conditioners work to purify the air in your home—it’s one of the most important features of a comfortable, air conditioned home! What you may not know is that, however frequently you change your air filters and scrub the counters and floors, germs and allergens run rampant in your home.

That’s why we recommend to our customers that they consider installing a Global Plasma Solutions Air Purification System in their home. If it sounds fancy, that’s because it is! It’s highly advanced technology that comes at a surprisingly affordable price point. Read on to learn exactly how these units use cold plasma to zap germs, allergens, odors, and bacteria in your home.

It’s all about ions.

Ions are found naturally in Earth’s atmosphere. The GPS patented technology produces the same levels of ions that are usually found around waterfalls, the beach, or high in the mountains and releases them in order to recreate those levels of odor and bacteria control in your home! So, basically, life’s a beach!

The result of this ion release is better control of allergens, incredible odor elimination, and the destruction of pathogens. When we say pathogens, we mean virus, bacteria, and mold! When the ions combine on the surface of a pathogen, they rob the pathogen of the hydrogen necessary for them to survive. The result is an inactive pathogen—meaning a pathogen that cannot latch on to you, your kids, or your visitors!

Yes, it’s affordable.

While there is a cost up-front, the GPS technology is much more affordable than its competitors, mainly because it does not require that you regularly replace parts or pay for frequent maintenance. Not to mention the medical bills and allergy prescriptions that you’ll be saving money on!

It was important to our team at BNG Heating & Cooling that we find a product that would have incredible benefits to our customers while maintaining a low price point. With the GPS Air Purification System, we’ve done just that! Go ahead and give us a call so that we can bring a crew in to find out if your home is a good fit for one of these systems.

How To: Keep Pollen Out of Your House

Raise your hand if spring allergies are your biggest enemy right now! 🙋🏽

You’re in good company! With last year’s allergy seasons being one of our worst, we’re all a little more weary of the threat of all this pollen infiltrating our homes. As you know, we at BNG Heating & Cooling are passionate about keeping your home comfortable! Here’s what we recommend to our customers who struggle with both indoor and outdoor allergies:

Give your house a deep clean.

There’s nothing better than starting with a clean slate. If you already have dust, pet hair, and dirt filling your house, you’re only spreading it around when your ventilation system circulates air. Do your best to deep clean or hire a professional to rid your home of these big offenders, and you’re already well on your way to a sniffle-free home.

Make sure you’ve changed your air filters.

What good will a clean home do if your filters are full of dust and dirt?! If you’ve given your house a deep clean but forgot to change your air filters, you can bet that there will be a layer of dust on all your shiny surfaces within a week. It’s even more important to change your filters before pollen fills the air because, if you don’t, you’re putting yourself at risk of breathing in pollen-filled air all day and throughout the night.

Schedule your HVAC maintenance appointment.

When you’re on one of our maintenance plans, an experienced technician is able to regularly check your system to make sure that it is a) running properly and that it is b) conditioning your air properly. We’re also able to assess whether you should invest in a more heavy-duty air purifier. It’s true that we often go noseblind to the smells in our house, and the same goes for how we become accustomed to the thick and muggy air in our house. It’s a really smart move to have a professional come in and asses your situation on a regular basis.

If you’re ready to make your home comfort, energy efficiency, and air purification a priority, then it’s time to give us a call. We’re ready to send one of our technicians to your house today!
