What Are the Benefits of a Zoned Air System?

...
 

What would you do if you love a warm room, your daughter enjoys a cool one, and your son wants some cold? Well, some of you have to compromise unless you have a zoned air system installed in your home. 

What is a zoned air system?
A zoned air system is a heating and cooling technique that regulates and redirects temperature customized air to certain areas or rooms in your home. As a result, each room (zones) has customized temperature for comfort and efficiency. 

Do you need zoned air system?
Every household requires a zoned heating and cooling system. In our homes, we have rooms that are either too cold or very hot. Every family member also has unique temperature preferences.  

Here are some benefits of zoned air systems in your home: 

Energy Efficiency 
A zoning system reduces electricity consumption significantly to cool or warm a house. Unlike previous heating and cooling systems, zoned ones provide temperature customized air to a specific room when required and not the entire house. Reports indicate that when used with thermostats, they can reduce the electricity bills by approximately 30%. 

Enhanced Comfort 
By customizing room temperatures, your home provides state of the art comfort. Your guests and family members will not be worrying about changes in temperature since regulation is just a click of a button away. Furthermore, during winter and summer, rooms with extreme temperature fluctuations will be a thing of the past. 

Upgrading an Existing system 
If you have an already existing heating and cooling system, upgrading it is possible. However, it’s not a DIY thing.  You need the services of experienced professionals to ascertain the condition of your system and items you may need for upgrading. In most cases, you will require the following: 

  • Zone control panel 
  • Zone dampers 
  • Thermostat 
  • Bypass damper

Why Humidity Control Is Important

...
 

Most people worry more about the temperature of the air in their home than the humidity. In fact, humidity is a hugely important part of the climate in your home, and it can affect more than you know. Here's why controlling the humidity in your home is so important.

Occupant Health

If the humidity in a home is too low, it can actually cause the occupants to have dry throats, eyes, and skin. It can even lead to nosebleeds for some people. This is often a problem during the winter where the high heat in homes can reduce humidity.

Some homes are too humid, which can also present plenty of problems. If your home is too humid, it creates a better environment for dust mites, mold and mildew. Allergens also thrive in high humidity conditions.

The bottom line is humidity plays a big role when it comes to indoor air quality, and that air quality directly can directly affect the health of you and your family.

Effects on Your Home

For homes that aren't humid enough, there can be some problems that go beyond the air simply being dry. Without enough moisture in the air, wood floors and furniture can dry out and eventually crack. It can also cause problems in your bathroom and around windows. The caulking in various spots around your home can actually become too dry if the humidity is too low, which can cause it to weaken and lose its effectiveness.

If your home is too humid, there's a good chance you'll see some mold growth around the house. Your windows may have a build up of condensation, which can drip down onto the window and eventually rot the wood. For homes with wallpaper, it may peel off when the air is too humid.

Ideally, you should try to keep your home in the range of 40-60% humidity year-round. Contact an HVAC professional at Carolina Comfort for more details on controlling the humidity in your home.

Why is the AFUE Rating Relevant?

...
 

Annual Fuel Utilization Efficiency is used to measure the gas furnace efficiency in converting fuel to energy. Hence, a high AFUE rating means a higher energy efficiency and the reverse is true. The importance of this evaluation is:

To know the efficacy of a boiler system
Most heating systems have this AFUE rating which helps customers see the efficiency capability of the system that they are purchasing. Research shows that a boiler should have a minimum score of 78%. This means that if the system has an AFUE of 90% then it'll use 90% of the fuel to create energy, and the 10% will be lost to the byproducts of combustion.

Helps in knowing the best system that meets your needs
The AFUE ratings should be compared against the heating needs in a household and the energy use. It is therefore essential to know the heating needs in the outside environment precisely. Thus it's best to seek advice from a professional who will help you choose the best-fitted heating system.

Assists in budgeting
The rating is necessary because it assists in knowing how much to spend on fuel. This is because if one has a heating system with a low rating, then it means that it will burn a lot of fuel to heat the house efficiently thus spending a lot on fuel. Hence a system with a higher AFUE rating will maximize the fuel it has therefore cheaper. It also great assists to shop for furnaces and comparing cost.

The AFUE rating is necessary because more efficiency translates to more heat per unit.It gives guidelines on the effectiveness of the heating systems, and with advice from an electric technician, the customer can know the appliance that best suits their needs. The rating also sheds light on how much fuel is needed by a heating system.

What MERV Rating Should I Use?

...
 

Although your heating and cooling system does its job well, it needs a little bit of help when it comes to keeping the air clean. However, there are lots of choices when it comes to air filters, so which one should you choose?

What Are MERV Ratings?

As air is pulled through the vents and distributed to various rooms in your home, it passes through an air filter. This air filter helps to remove some larger contaminants from the air, such as dust, mold spores, pollen, carpet fibers and more. The MERV rating of your air filter determines how well it filters out particles. The higher the MERV, the smaller the particles your filter can remove from the air.

MERV ratings can be as low as 1 and as high as 16:

  • An air filter with a MERV of 4 will remove particles larger than 10.0 pm, including pollen, dust mites, sanding dust, spray paint dust, and carpet and textile fibers.
  • A MERV of 8, the minimum recommendation for commercial buildings, particles of 3.0 to 10.0 pm are filtered, including cement dust, dusting aids, hairspray and mold spores.

Choosing an Air Filter

Now that you've got a basic understanding of MERV ratings, you can choose an air filter for your central heating and cooling system. Of course, the rating you opt for depends on how much you value indoor air quality.

At the very least, you should have an air filter with a MERV of 4 or higher. This provides minimal filtration for residential buildings. If you want to filter out more contaminants—especially if you're worried about mold spores—you should get a filter with a MERV of at least 8.

Conversely, you probably don't need to go any higher than a 12. A high-quality air filter with a MERV of 12 will filter out milled flower, lead dust, humidifier dust, and even legionella bacteria. If you're looking for great air quality in a residential home, these filters are a great choice.

Replacing Air Filters

Even though Columbia, SC, has pretty good air quality, your filter still needs to be replaced every now and then. The general rule is to replace it at least every three months, although that depends on a number of factors. If you'd rather not undertake this job yourself, you can always contact a professional for AC/heating maintenance.

Why Is My Furnace Turning on and Off?

...
 

Figure out why your heating and air conditioning equipment is struggling.

HVAC service technician inspecting a residential furnace

Keep your heating and air conditioning equipment in good working condition by paying attention to signs of trouble. If your HVAC equipment is quickly turning off and on, then you likely need the help of a professional. Aside from one easy fix, this problem usually boils down to a serious component failure, requiring a technician who can do the job right.

Here are the most common reasons for quick HVAC cycling:

  • Dirty filters: A clogged filter will restrict airflow. This prevents warmed air from moving through the system. It backs up in the furnace instead and quickly leads to false readings. Because the heater is hot enough, it shuts down, leaving the house cold and once the air in the unit cools, it kicks on again. Thankfully, this is easily remedied. Talk to your HVAC specialist about the best filters and filter changing schedule for your system.
  • Clogged outlets: There are pipes leading from your system to the outdoors. They can vent through the attic and roof or an outer wall of your home. If clogged, warm air will pool and lead again to false readings.
  • Failing electrical components: Sometimes it isn’t the furnace at all, but the thermostat that’s to blame. However, there are sensors inside your heating unit that can fail and cause bad readings as well.

How Often Should I Change the Air Filters in My Home?

...
 

Maintenance agreements keep you up to date on best practices for home HVAC unit care.

A Clean Filter Beside a Dirty Air Filter

You can count on maintenance agreements to help you with all of the HVAC filter changes you’ll need throughout the year. Discuss the best schedule for swapping them out with the technician who visits your home. You can even ask for a demonstration, so you’re never worried about making a mistake and causing a problem for your HVAC system.

Your filter changing schedule depends on a number of factors:

  • What is the MERV rating of your filter? MERV stands for Minimum Efficiency Reporting Value. It’s a numeric rating system aimed to help people choose filters based on how many contaminants they want removed from their indoor air. The higher the MERV rating, the more contaminants are removed and the faster a filter will be clogged and need to be changed.
  • How clean are your ducts (and your house)? The more dirt and debris that winds up in your ductwork, the more particles will be caught in your filter. It makes sense to change a dirty filter as soon as is reasonable. Dirty units will block the flow of air and lead to energy waste.
  • What size filter does your system take? There are plenty of sizes which work well with flat, affordable air filters. Others require ultra-thick filters or permanent, washable units that need to be changed just a few times a year.

Maintenance agreements often provide just two HVAC visits a year. Make the most of them by asking your technician how to better maintain your units in the meantime. Click this link or call our friendly team of experts at Carolina Comfort, Inc. at

How Can I Prevent Hot/Cold Spots in My Home?

...
 

Zoning increases energy efficiency and creates even temperatures throughout your home.

HVAC service technician working on a zoned system in a home

Improve energy efficiency and make your home more comfortable by investing in a zoned HVAC system. Traditional systems apply the same standards to every room in your house. In contrast, a zoning system splits your property into groups of rooms with similar heating and cooling needs and deals with each of them individually.

Consider the benefits you get from zoned HVAC systems:

  • Eradicate hot and cold spots in your home. Nothing is as frustrating as walking from one chilly room into the next where the heat is overwhelming. Zoned systems don’t use one sensor to evaluate the comfort of your home. Zone temperatures are tracked separately, so heat is delivered only to those areas in need.
  • Save on your utility bills. Zoned systems only deliver warm or cool air to spaces that need it. By doing so, your home ends up using less energy and you will enjoy lower bills.
  • Increase your property’s value. Zoned HVAC systems are more effective and cheaper to run than traditional heating and cooling designs. They’re also seen as advanced technology. Combined, those benefits lead to higher property value, so if you’re considering selling your house anytime soon, a zoned HVAC setup will help you get more for it.
  • Our friendly team of professionals is here to answer your questions and provide the energy efficiency solutions you need for your home or business.
