Good News for Old-house Owners

Surely you have seen many remodeled Charleston homes. They all look really gorgeous while holding that historic aesthetic that we love. One issue often remains, though… and that is that many forego to inspect their old air system. Many of these homes have a new coat of paint, but what lies in the old ductwork can be surprising.

It’s a smart idea to have the home air system inspected. Older homes and even many new ones have ductwork that might have been damaged or exposed to water and humidity. Black mold can be found in any environment that provides food for the mold to thrive, including inside walls and inside vents and other duct work. When you notice black mold in air vents cleaning the vents out is the first step, but you’ll also need to eliminate the source of the mold to eliminate it completely.

Mold can be killed with a mixture of bleach and water, but chances are good that you won’t be able to reach the mold deep inside the duct work of the home.

How do we address black mold:

A test can be ran to identify if mold is the actual issue. If mold is discovered, we then identify the cause of the mold in your home. Wet walls and baseboards can contribute to mold. We check the insulation surrounding the ductwork. If the mold in the air vents has extended into the surrounding insulation, it will need to be replaced.

When we see that the duct needs replacing, we will suggest the best steps to clean, replace and prevent mold from reoccurring. Blanton & Sons is certified by NADCA. Since improper removal of mold can be a waste of time, and money, you can rest assured that we have the proper experience and specialized knowledge in removing mold.

Keeping Crawl Space Moisture Out of Your Home

50% of household air can flow up from your crawl space.

This is why it’s important to keep this unseen space as clean and dry as possible. Crawl space conditions can cause moisture to enter homes and have a negative impact on indoor air quality.

The process to address this is with encapsulation and creating a barrier between the earth and your home. Water vapor travels from the ground and even through cement. A heavy-duty polyethylene barrier and dehumidifier will greatly improve indoor air quality. With less humidity seeping into your home, you will also see energy improvements.

The sealing involves covering the dirt, foundation walls and sometimes the ceiling. This is most effective when the edges of the barrier are closed off with sealing tape. The last step is adding a dehumidifier. Combined, the encapsulation and humidity control will keep the moisture away and all the problems that come from it.

Common signs that lead to sealing a crawl space:

  • Mold

  • Mildew/musty smell in basement

  • Soft or separating floors

  • High cooling costs

  • Wet insulation

  • Sweating windows

  • Insect problems

Benefits of Creating a Vapor Barrier

  • Improved air quality in your crawl space and home

  • Creates inhospitable area for pests and wood-destroying insects

  • More comfortable living conditions

  • Avoid fungi/mold issues and structural damage

  • Greater energy efficiency in your home

Why a Mini Split Air System?

Mini splits can be more affordable than traditional heating systems since they require no ductwork.

Ductless mini split systems provide the ultimate comfort and efficiency. These systems are quiet while heating or cooling rooms evenly. Mini splits can be much more affordable than traditional heating systems since they require no ductwork. Due to the design and reversible motor, the system can cool or heat your home!

Get an Air Scrubber Plus on us!

Air quality is important and no one wants to breathe dirty air. Clean air can differ among many people. Some people are sensitive to mold, bacteria and other allergens while others are not as sensitive. A regular air filter can only do so much and won’t stop most of the airborne bacteria that we breathe. That’s where UV lights come in.

Air Scrubber Plus - UV Bulb for HVAC

These lights can be installed in your air system to fight against the allergens that slip by air filters. The light kills the harmful bacteria instantly. These lights can also keep indoor AC coils from growing mildew as these coils stay wet for many months of the year.

Blanton and Sons is offering a free Air Scrubber UV Bulb with and new duct install. Ask us how to receive yours as this offer only lasts through to the end of February.

UV Light Bulbs act as an air filter to kill airborne allergens such as mold and bacteria..

This Christmas, we are giving away free Nest Thermostats to every new HVAC install.

The Nest Learning Thermostat is the very first thermostat to get ENERGY STAR certified. In under two years, it can pay for itself. But with a special end-of-the-year offer, Blanton and Sons will give you a Nest at no cost when you have a new HVAC unit installed.

Over a short time, the thermostat learns what temperature you like and builds a schedule around yours. Independent studies show that it has saved people an average of 12% on heating bills and 15% on cooling bills.


Follow the Leaf.

Change the temperature to save energy and you’ll be rewarded with a Leaf. The Leaf learns how to help you save, so it appears at different temperatures for different families.

Simple installation.

Pop off your old thermostat and install your new Nest.

Good night, Nest.

You turn down the heat on your way to bed. Nest gets to know what you like and starts building a schedule: cozy in the morning and cool at night. 

A warm welcome.

After you turned up the heat a few days in a row, Nest learned you like eating breakfast at 70º. So now it warms up the house as you get out of bed.

It knows when you’re away.

You’re off to work. The Nest Thermostat can use sensors and your phone’s location to check if you’ve left, then sets itself to an Eco Temperature to save energy.

Using Google Home with your Nest Thermostat

The holidays are here! And you may not know it yet, but there's a good chance that Santa has some new tech coming your way. So we sought out to give you a few tips on how to make your home a little smarter. 

Nest has been the leader in Smart Thermostat industry for a while. You are able to set the temperature through your phone even when you're not around. But when you are home, wouldn't it be cool just to ask Google to turn up the heat? 


Well, you can with just a few steps. With Google Home, you can ask the Google Assistant questions about the Nest Thermostat's status and tell your Nest change the temperature or set it for a certain amount of time. The Google Home can also play certain notifications from your Nest. 

1. Setup your Google Home and Nest Thermostat
2. Learn how to link the two by following the steps here

When all is done, try asking Google some of these phrases:

  • Hey Google, what’s the temperature inside?

  • Hey Google, make it warmer.

  • Ok Google, set the temperature to 68 degrees.

  • Ok Google, raise the temperature 72 degrees.

The Overwhelming Decisions of Duct vs Ductless

Starting a commercial renovation project comes with a number of decisions that need to be made. While you may feel comfortable making some of these decisions, such as choosing the best layout and looking at interior design. You may, as a business owner, feel less than qualified to choose on the right HVAC system for your new space. A ducted or ductless air conditioning system? You’re not an HVAC expert, so how should you know the best route to take. 

minisplit vs central air

You may already be aware that a ducted system distributes air through a series of air ducts that are generally constructed from sheet metal and are installed behind the walls, ceilings and floor of your space.

Unlike a ducted air system, a ductless or minisplit system doesn’t use ducts to distribute the air. These units are designed differently: where central air uses one unit to produce cool air, the ductless system consists of small air handlers installed throughout the home.

When to use a central air system:

You already have ducts. You live in a humid environment. You need better air flow. Aesthetics is a major concern. You’d like to minimize maintenance costs.

DUCT compared to DUCTLESS

When to go with a ductless minisplit system:

There is no space for ducts. You’re adding to your home. Dust is a problem. Your space has different zones with different temperature requirements.

It's  so easy to create custom comfort zones in your space by individually controlling ductless air handlers. This can also come in handy to settle those office air conditioning battles over temperature issues!

Every HVAC system is elaborate and must be designed to meet the needs of your space. It pays for itself to bring in a qualified team of experts to design the best fit for you. Don't allow your building contractor to install your HVAC system as they may not be qualified and have the best understanding. 

Your Pet's Don't Need the AC or Heat

You know by now that a programmable thermostat is a great way to help lower your heating and cooling bills. You’re given the freedome to adjust your home’s temperature from anywhere. You can have the home cool and ready when you come home from work or not leave the heat blazing all day while you're gone. 

With this option in mind, pet-owners still worry about turning the temperature down and leaving their pets without heat. Fear not! It is practical for cats to find a sunlit spot to lay down so they can adjust their body temperature. In the other world, dogs are actually able to handle colder climates in general. A healthy household pet will be fine if you lower your thermostat while you’re not at home.

Of course talk with your vet. They are always the best person to discuss with to find out tappropriate temperature to set your thermostat for your particular pet during the winter. 

 Other tips to keep them warm and healthy during the seasons:

* Make sure your pets stay hydrated with fresh water
* Put out some extra food during the cooler seasons.
* Be sure bedding is dry and add extra layers if needed.

We know air conditioning and we love our pets.

Behind the New Logo and Identity of Blanton and Sons

Blanton and Sons

Established in 1998 by Jimmy Blanton as Blanton’s Heating and Air, we found that it was time for a rebrand as we continue into a new chapter. We proudly introduce our new look and name, Blanton and Sons. It has been 20 years since the beginning and we have found ourselves as leaders in Charleston’s air conditioning and mechanical industry. We have grown so much as a team and as a family. We couldn’t ask for a better staff and crew of technicians that go above and beyond to serve our customers in the Lowcountry. 

For many years, the polar bear has been our mascot and while despite an intense affection for the bear and all it’s cuteness, it was time to display our professionalism and experience. We have retired the bear, as we see it highly used among competitors. These days, the line between heating and cooling have become known as one type of service. Therefore, we decided also to retire the red color and go with a monotone blue color palate. Bright blues can be seen with darker navy blues to give an all around mood of “Keeping Cool”.

Take a look at where our branding has changed over the years:

Blantons Since 1998

The identity can work on different visual wavelengths but it all feels consistent and coherent. The older brands were generic and felt distant which seemed contrary to the cool vibes that we aim to convey. It has come time to separate from the competition and doing so in a unique voice with good design.
