Comments Off on What’s a SEER?
SEER stands for Seasonal Energy Efficiency Ratio.
Every system (composed of an outdoor compressor bearing unit that matches with an indoor unit) is evaluated and then given an Energy Efficiency Rating. This is a lot like the miles per gallon rating that your car gets, but instead of gasoline it is a number that is used to calculate your energy savings. The more cooling/heating a system puts out for each unit of energy it consumes, the higher rating it will receive. The higher the efficiency rating of your system, the less energy it will consume…that means lower utility bills and less of an impact on the environment.
So shouldn’t I just go with a higher SEER value?

At first glance you would think that the higher the SEER value the better, however that’s not always the case. You will definitely be saving more energy when operating a higher SEER system, but you might not be saving money overall. Typically, the higher the SEER value the higher the cost of the system (all other things being the same). There are really two determining factors for you when choosing the SEER value for your system: the length of time you plan on being in your home and your preference to be environmentally friendly. If you have the conviction to be as green as possible no matter what the cost is then you want to go with as high of a SEER value as possible. We wish everyone could choose this option. However, the reality is most people want to be environmentally friendly but must also live within a budget. The good news is that as technology advances our heating and cooling will require less and less energy.

So how do I determine which SEER value is for me?

The determining factor in finding the right SEER value for your HVAC system is how long you plan on living in your current house. Follow along with this example to understand this better:

The minimum SEER value allowed is 13. That will serve as our base. Here are the annual operational costs of an average family for various SEER levels. These values will change depending on a number of factors including your utility company and how high or low you keep your indoor temperature among other things.

13 SEER = $805.00
14 SEER = $747.50
16 SEER = $632.50
23 SEER = $448.50

Now at first glance it looks like a no-brainer. The 23 SEER system costs nearly half as much to operate as the 13 SEER system. However, the 23 SEER also costs significantly more (sometimes twice as much) as the 13 SEER system. So let's just say for the sake of the example that a 13 SEER system costs $4000 and a 23 SEER system costs $8000. You would need to be living in your home for over 11 years before you began to save money on that system. So if you are planning on living in your current home long-term then this would be a great investment for you, especially on year 11 when you start saving almost $400 a year! However, if you are living in a starter home and plan on moving in a few years, while a higher SEER system will add value to your home for resale, you might want to consider a lesser SEER value for upfront savings.

Finding a home that requires the same amount of cooling and heating throughout is a challenge. In fact, it’s probably impossible. Basements, attics, first floors, second floors, fronts, backs – all have unique needs based on the home’s size, windows, facings, insulation, doors and even the home’s position towards the sun. In the past, it has been difficult to mitigate these differences. Homeowners were simply forced accept the fact that some areas of the house would be comfortable, while others would not.

Total Home Comfort Can Be a Reality

When the only option for modern cooling and heating was a ducted central HVAC system, the reality of the uncomfortable home was normal. In recent years, however, there have been significant advances in cooling and heating, including zoning.

A zoned home is divided into segments based on each area’s need for conditioning. Rather than relying on a single unit to cool or heat the entire property, multi-zoned homes utilize a network of small, energy efficient units and thermostats to send the right amount of conditioned air to each zone. This allows homeowners to have room-by-room control.

Homes that can benefit from zoned systems include:

  • Homes with two or more stories
  • Homes with finished, livable basements
  • Rooms that get blocked off in the winter or summer because of comfort issues
  • Rooms with large windows or high ceilings
  • Large families that often find themselves battling over the thermostat
  • Older, historic homes in which traditional ductwork is implausible

Zoning Provides Room-by-Room Comfort Customization

The number of zones a home can benefit from will depend on its size and layout. In some cases, a single zone can cool or heat an entire floor. In others, a multi-room system would be used to divide the home up into several temperature control zones. The greatest benefit of zoning is the level of customization that can be achieved. You can cool and heat only the zones in use, which not onlyimproves personal comfort, but reduces overall energy consumption and costs.

While ducted HVAC systems can be “zoned”, they never quite achieve the same level of customization and precise control that is possible with a ductless system. When every segment of the house is manageable by its own unit, it means that every room of the home and every family member in the home can achieve total comfort, no matter what time of day or time of year

nov3   Are you looking for an efficient, low-cost solution to satisfy room temperature troubles? No matter what size space you’re trying to cool or heat, discoverenergy efficient savings and eco-friendly solutions, while keeping the temperature just right inside your home. Imagine the possibilities with a ductless temperature controlled system.

Where’s All the Money Going?

Central air and other similar ducted systems are catch-all heating solutions that lack the precision and control of their ductless counterparts. When a forced air system works to cool or heat your home, you have little control over where that air goes. This means that vacant rooms are getting the same amount of energy and service as your favorite spots in the house.

It’s wasteful, inefficient and expensive to cool or heat the basement storeroom the same way you cool or heat the kitchen or bedroom. But a ducted system doesn’t allow for that kind of precise control. So the cold or warm air flows throughout your home and you see the results of this inefficiency on your utility bill every month.

How can you target the specific rooms you use the most and divert some of the energy and costs from the ones you don’t?

Where Traditional HVAC Falls Short

There are several ways that traditional systems fall short:

  • Thermostat placement is rarely conducive to providing accurate comfort control in other areas. For example, thermostats can often be found in a home’s master bedroom. When the temperature in that room is adjusted, the children’s room across the hall may not be receiving the comfort that it needs.
  • Ductwork tends to run through uninsulated spaces, which leads to thermal heat loss. If there is a leak in the ductwork, or if flex-ducting is pinched due to improper installation, duct-loss will lead to wasted energy as the system has to compensate for the wasted energy.
  • Lastly, conventional systems use a standard single speed compressor that can only run at full speed. This means that the system works at full capacity until the desired temperature is achieved, then shuts off. As the temperature changes, this cycle repeats and can create uncomfortable drafts and expensive energy spikes.

The Targeted Solution

Would you like to get back in control in less than two days? An easy-to-install ductless system has proven technology that is far more energy efficient than traditional HVAC and up to 40 percent more efficient than window units.

Here’s a how a ducted system works inefficiently; it notices that the temperature is, for example, two degrees higher than what it ought to be. It turns on, works frantically to pump cool air throughout the home and when it senses the temperature has lowered, it shuts off. Gradually, the space warms again.

On the other hand, the Mitsubishi Electric ductless system uses an INVERTER-driven compressor to provide exact control 100 percent of the time. They constantly adjust to even the slightest temperature changes in the room so that it doesn’t fluctuate – and they don’t waste money or energy on the zones where you spend little time.

The ductless unit is installed to deliver room-by-room comfort in the spaces you choose. The majority of your cooling and heating energy (and money) goes where you need it, and not where you don’t. In this way, you get personalized comfort in the rooms you use most. This is known as “zone control”.

Even More Ways to Save

Most ductless systems have earned the ENERGY STAR, which means savings as they operate, as well as applicable ENERGY STAR rebates. Some units are eligible for state or federal tax credits, or local utility discounts. The biggest long-term savings comes from using a system that works efficiently. According to the ENERGY STAR website(link is external), “Replacing your system with an ENERGY STAR certified model could cut your heating and cooling costs by 30 percent.”

Big or small, no matter where you live, outdated technology costs more to operate. Ducted systems work round-the-clock sending cold or warm air to vacant rooms and they also use unnecessary energy as the temperature naturally fluctuates. INVERTER-driven compressors in ductless systems ensure the optimal efficiency of the energy they expend; you save even more by concentrating your temperature control efforts in only the rooms that matter.

nov2   Most people have heard of ductless cooling and heating systems, and they have probably seen the small, indoor devices installed high on walls in homes, restaurants or office buildings. But what do you really know about these systems?

1. They Offer Highly Flexible Solutions

Whereas traditional heat pumps and central air conditioning systems force cooled and heated air through ducts, ductless systems deliver air directly into different zones. They are comprised of a small outdoor unit and one or more indoor units that require nothing more than mounting capabilities and access to electricity. Sometimes referred to as split systems, multi-split systems, or split-ductless systems, ductless cooling and heating offers home and business owners a cost-effective way to replace inefficient window units, space heaters and electric baseboard heaters. They can be installed in home additions, new construction, condominiums and apartments, or to improve temperature control in specific rooms. Ductless systems can even be fit for buildings that currently use ducted forced-air systems.

2. They Save You Money

One of the biggest reasons why homeowners switch to ductless cooling and heating is overall cost savings. In recent years, utility costs across the country have skyrocketed. When a home’s temperature depends upon an inefficient system, monthly bills can quickly climb out of control. Ductless systems operate on less power – they are smaller than traditional forced-air systems, and because the temperature-controlled air is delivered directly into a room, there is no loss in efficiency. Multi-split systems also allow homeowners to create “zones” in their home, which means they no longer have to cool or heat rooms that aren’t occupied. In addition to saving money on utilities, homeowners may also be eligible for tax credits or utility rebates for the year they install a ductless system. There are many programs at the federal, state and local level that allow homeowners and businesses to take advantage of these additional savings.

3. They Improve Indoor Air Quality – Happy Breathing!

Often times, the quality of indoor air can actually be lower than the quality of outdoor air. With traditional HVAC systems, air ducts must be professionally cleaned on a regular basis, and even after cleaning, dust and allergens are left behind. Ductless systems, on the other hand, offer multi-stage filtration that can drastically reduce dust, bacteria, pollen, allergens and other particulates in the air.

4. They Are Quick and Easy to Install

Installing a traditional, ducted system can take several weeks and disrupts daily activities in the home. Ductless systems are far less invasive to install, and depending upon the number of indoor and outdoor units required, can be up and running in as little as one day. Multi-split systems run on small pipes that require a mere three-inch hole. That means homeowners don’t have to worry about rebuilding walls or ceilings around ductwork and there is no loss of precious square footage.

5. Ductless Cooling Lowers Your Carbon Footprint

The small size of a ductless cooling system and its zoning capabilities allows for greater energy efficiency. Ductless cooling and heating systems follow ENERGY STAR guidelines, which means they are far more energy efficient than the minimum standards set forth by the U.S. federal government. Improved efficiency saves money, of course, but it also helps reduce your total carbon output. Additionally, ductless systems take advantage of advances in chemistry to reduce effects on the environment. Ductless systems use a refrigerant called R410A, which is known for its zero ozone depletion potential. This means the system will have less impact on the environment throughout its lifecycle. Ductless cooling and heating systems are energy efficient, environmentally friendly and completely customizable. They offer homeowners the ability to cool and heat specific zones of their home to the exact temperature they desire, providing consistent and exceptional year-round comfort.
