When to Choose a Ceiling Cassette Air System

ceiling cassette

If bulky, wall-mounted mini split units aren’t your thing, a ceiling cassette can provide your room with that seamless look. 

Ceiling cassettes sit above the ceiling where the mechanics are hidden. They fit between regular ceiling joists and their air flow covers large spaces.

When Choose a Ceiling Cassette Air System

If you have a large room with hot spots, a ceiling cassette can fix that. They have four outlets that blow air and offer the option of closing one or two vents if you have a direction you'd don’t want to air blow. This becomes useful in hallways where you might only want to direct airflow in two directions.

Features of a Ceiling Cassette

If you're installing a ceiling cassette unit in a large living room, but you’d also like to condition a separate and adjacent room, you might not require a separate unit. Many ceiling cassette models will support the use of a branch duct to move some of the air to the other room.

Many units are capable of being connected to a fresh air intake, meaning that instead of recycling the air in your home, you can draw and cycle fresh air throughout your home.

To adjust the air, you can use a wireless remote control or a wired-in wall mounted control.

Flooding and Your AC Unit

While an air conditioning unit is designed to withstand weather conditions, sometimes you’ll need to call your technician to inspect for damage. If your AC unit is in standing water, due to flooding, it can cause severe damage to the electrical and moving parts. Generally, the water must reach roughly a foot in depth to affect your air conditioning system, but if you’ve experienced flooding of any kind, call Blanton & Son’s for an immediate inspection.

To avoid further damage or danger to you and others, we advise you to take these steps:

  • Turn off all the electrical switches to your system. If you are not comfortable doing this, you can call us to help.

  • Allow your unit to dry out. Get rid of any standing water if possible and use caution clearing debris from around the unit.

  • Leave your air off until a professional inspection has been performed.


Don’t cover your HVAC unit with a tarp. This can cause it to rust due to not allowing the unit to air out..

For a full inspection and safety check, call Blanton & Son’s after making sure to have read all of these guidelines.

Three Money-Saving Myths

Heating and cooling your home contributes to almost 50% of yearly energy bills. Sounds like a good place to cut energy use, right?

The answer: Avoid doing things with your thermostat that waste energy.

A “faster” approach to heat or cool your home

You get home from work and and it’s 80° and you prefer it at 75°F. The next thing you do is set the thermostat to 72°, so that it will cool off your home faster.

Not a good idea.

This doesn’t make your air conditioner work faster… it only works at one speed. Lowering the temperature setting past what you need just makes the air conditioner run for much longer to reach the lower temperature.


Leaving your thermostat at the same setting

Do you set your thermostat at a specific temperature and never touch it? You could be wasting up to $200 each year. (Source: ENERGY STAR}

Instead, you should adjust the temperature whenever you leave your home for more than 8 hours. After all, there’s no need to heat or cool your home at the same temperature as when you’re there.

  1. Set your thermostat roughly 5° higher in the summer and 10° lower in the winter.

  2. When you get home, set the thermostat back to your comfortable setting.

Doing so can save you up to 15% on your yearly energy costs. And if this habit isn’t for speed, you can ask us about programmable thermostats.

Tampering with your thermostat too much

Those who micromanage their thermostats use more energy than those that leave them alone. Constantly changing the set temperature on your thermostat causes your AC to stop and start, which causes it to run inefficiently.
Imagine you have your thermostat set at 75°F in the summer. Your AC cools your home until it reaches that point then shuts off. Then you realize that you still seem hot, so you lower the thermostat a couple more degrees. The air must now immediately turn back on.

Your system should be running for longer, steadier times to save money. Picture your car’s MPG… Does mileage improve on streets with lots of stoplights or on the interstate?

In summary

  • Don’t crank your thermostat up or down to cool your home faster.

  • Adjust your thermostat temperature 5°F when you’re away from home for 8+ hours.

  • Don’t repeatedly change the thermostat setting when you’re home.

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

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.
