Why You Should Consider a Ductless Split System for Your Home

While many people are familiar with central air and heating, a ductless split system may be a new concept to many. Ductless systems work in a way similar to window units, where they directly cool an isolated area; yet, these systems have one unit that is installed within the home itself (generally close to the ceiling) while the other half of the system is installed outdoors, much like a central HVAC system. These units are a great solution for many homes, particularly those without ductwork. They also have many benefits over a traditional window unit.

If you’re used to more traditional HVAC systems, you may be missing out on the great benefits of owning a ductless system. Take a look at this rundown of all the perks that a ductless split system could offer to you and your family.

Money Savings

Ductless Split Systems can help you save money. This is because many of the more traditional systems use more energy to operate. A ductless system is smaller than a typical forced air system and is specifically targeted to individual rooms, so no energy is wasted cooling or heating unoccupied rooms.

Additionally, homeowners may qualify for certain tax credits or rebates for the year they install a ductless system—talk about a double dose of money savings!

Easy Installation

Ductless systems are actually pretty simple to install. Unlike traditional systems that rely on ductwork and can take time for proper installation, a ductless system in much faster. to install. Depending on the requirements of your home, you very well could have your ductless system installed and running within one day! These systems are also not at all invasive, meaning no major disruptions to your home during install—they only require a insignificant hole to access the small pipes they run on.

Better Indoor Air Quality

Indoor air can be quite polluted due to the buildup of airborne pollutants in an enclosed space.  In traditional HVAC systems, air ducts tend to collect dust and other debris that can significantly impact the quality of your home’s indoor air. Ductless systems, on the other hand, offer exceptional filtration at multiple levels, which help combat dust, pollen, allergens and other airborne pollutants in the home.

Energy Efficiency

Both the size and the zoning flexibility of a ductless system encourage energy efficiency. All ductless cooling and heating systems follow ENERGY STAR guidelines, meaning that they are more energy efficient than the minimum standards outlined by the federal government. Many traditional HVAC systems are set at these minimum standards, or just above, and waste a lot of energy on operation. This  adds up on energy bills. Ductless systems however, are rated much higher than the minimum, not only offering improved efficiency, but also a better and more environmentally friendly solution to heating and cooling your home.

Is It Safe to Use a Window Air Conditioner During the Rain?

A window unit air conditioner is commonly used within homes to cool a small space. This type of system has a minimal cost, is easy to install, and requires minimal maintenance. However, this type of system can cause issues during times of heavy rains or other severe weather.

What Can Happen to a Window Unit During Heavy Rains?

If the window air conditioning unit is improperly installed, then rainwater can easily enter the home, resulting in damage to your flooring, walls and décor. if you use a wall air conditioner unit, it is important to understand how to prevent and/or remedy this issue so that you do not have damage in the home. Follow the simple tips below to care for your unit during rainy seasons.

1. Inspecting the System

First, inspect the window unit from every angle to ensure that the system has been installed properly. There should be no gaps between the window and the window frame where the unit comes in contact with the window. The side panels must also be installed seamlessly so that there are no gaps.

2. Make Adjustments

If you find that you have gaps in your system between the window and the unit, you will need to close these gaps. Check for both proper alignment and balance on the window frame as well as the alignment to the sash. Make sure that you tighten the sash and secure the top flange with no less than two screws to guarantee your unit will not move.

3. Check the Side Panels

The side panels of the air conditioning system can extend to fill in the window space and keep rain from entering the home. You must check this area to ensure that no rain will be entering the space, which can occur during a light drizzle or downpour. If you see any gaps or holes where water could enter the home, be sure to seal them with a silicone caulk so that the water cannot enter into your living space.

4. Additional Tips

  • It is common for damage to occur to the side panels of the system. When this happens, additional parts may need to be ordered from the manufacturer. If you have trouble tracking a water leak to your unit, you can seek out the water stains and damp areas near the frame. This can help you understand that you may have an issue with the actual window itself, instead of your A/C system.
  • When you close any gaps or plug holes that exist near your unit, you will be able to prevent any water from coming in, and it will also help maintain better energy efficiency in your home, translating to money savings on energy costs.
  • Be aware of safety hazards in the home. Be sure that when you install the air conditioner in the home, as you can have issues with the unit coming out of the window frame. If the unit is tiling forward you can also have issue with condensation moving improperly from the back or the bottom of the system.

With the above tips, you will be able to have your window unit system installed properly for the summer season and be able to enjoy the cooling comfort the unit can bring without any issue.

10 Geothermal Heating and Cooling Myths

Geothermal heating and cooling consists of buried pipes beneath the property and an indoor handling unit. The pipes heat and cool the indoor air as needed, through utilizing belowground temperatures, which stay relatively consistent.

10 Myths about Geothermal Heating and Cooling

These systems have been used for over 60 years, both in the United States and abroad. Many real estate owners are unfamiliar with just how the systems work, however, and there are therefore many myths surrounding their usage.

1. Since geothermal HVAC systems use electricity, they aren’t a renewable technology.

Geothermal HVAC systems use just one unit of electricity in order to move as much as five units of heating or cooling. This one unit delivers the energy from the earth to the building.

2. Wind and photovoltaic power are better renewable technologies than geothermal HVAC systems.

While photovoltaic power and wind power play an important role in adding to the electrical grid, geothermal HVAC systems actually remove four times the kilowatt-hours of consumption. Geothermal HVAC systems are quite often the best way to reduce conditioning’s environmental impact.

3. To Use Geothermal HVAC, You Need a Lot of Yard Space or Real Estate

Some earth loops can be buried vertically, which means that you won’t need much aboveground surface. The vertical position is dependent upon the physical characteristics of your land. Additionally, you can tap into an existing aquifer if one is available, which means you’d only need to use a few square feet of real estate.

4. Geothermal HVAC heat pumps emit too much noise.

In reality, these systems are very quiet, and since there is no outside equipment, your neighbors shouldn’t hear anything.

5. Geothermal systems don’t last long.

The indoor equipment usually lasts for decades and is less expensive to replace than traditional HVAC systems. While earth loops are more expensive to install, they usually last for generations.

6. Geothermal HVAC systems can only heat, not cool.

These systems cool just as well, and they don’t require an additional backup heat source. Some customers do prefer to have a small backup to use on the coldest days so their loop can be smaller.

7. Geothermal HVAC systems can’t heat everything at once, like indoor water, a house and a pool.

HVAC systems can actually be designed to heat multiple things at once.

8. Geothermal HVAC systems end up putting refrigerant lines in the ground.

The majority of systems only use water in their loops and lines, which makes them an even more environmentally friendly option.

9. Geothermal HVAC systems use a lot of water.

In the past, there have been “pump and dump” systems that wasted water after it passed over the heat exchanger; however, those systems are now very rare. In fact, geothermal systems actually don’t consume any water. Instead, the water is taken and returned to the aquifer.

10. Geothermal HVAC technology is too expensive.

There are federal and local incentives for purchasing geothermal HVAC technology, which makes the price competitive with most conventional equipment.

If you’re looking to lessen your carbon footprint without losing the often-needed ability to heat and cool your home, geothermal HVAC systems may be the answer. Speak with your HVAC company for more information.

Sizing Your New Residential Air Conditioner

The first step in buying a new air conditioner is figuring out the right size of air conditioner for your home. Air conditioners are sized in terms of tons of cooling capacity—one ton of cooling is equal to about 12,000 British thermal units every hour. An air conditioner with the right tonnage size will cool your home at maximum efficiency, but undersized or oversized units waste energy and may not cool your home effectively.

Why Size Matters

An undersized air conditioner won’t have the capacity to cool your home in a reasonable amount of time. Depending on your home’s volume and insulation, it may never manage to cool your home to your desired temperature. It will, however, run constantly and use up a huge amount of energy. You may save money on your initial purchase of a small air conditioner, but the high energy bills—and lack of comfort—simply aren’t worth it.

Some people buy oversized air conditioners deliberately, thinking that more powerful units will cool their homes better. In fact, oversized units will cool more quickly but the speed of cooling actually makes them less efficient. An oversized unit will cool the air in your home so fast that it will turn off before your building structure cools. As a result, the air will start to warm again right away, and your system will begin to cycle on and off repeatedly. This kind if cycling is both irritating and highly energy inefficient.

Chill Factors

Quite a few variables must be factored in to determine the right size air conditioner for your home. The size of your house is very important—not just the square footage but also the total volume of air that your house contains. In addition, you need to consider the area of the exterior walls that receive sun exposure.

Windows play a major role in determining your home’s cooling needs. You will need to consider the total number of exterior windows, the age and condition of your windows, and the number of windows that face the sun.

Insulation and ventilation are also important for air conditioner sizing. Different homes of identical volume may need different size air conditioners depending on the age of the home, the quality of the insulation, and the existing ventilation and ductwork.

Finally, don’t forget to consider local climate conditions as well as your own landscaping (i.e.; shade). With all of these factors, it’s almost always advisable to consult a trusted HVAC professional who can help you to calculate your air conditioning needs correctly.

An HVAC professional can also help you to make the other decisions that go along with buying a new air conditioner. Once you’ve identified the right size, it’s time to consider energy efficiency and performance quality at the right price for your budget.

Pitfalls to Avoid When Buying a New AC or Furnace

Over time, all homeowners face significant expenses for the upkeep of their property. Sooner or later, the need to purchase a new air conditioner or furnace is a pretty likely scenario. If you’re unprepared to make an educated purchasing decision, you can potentially buy an AC or furnace that performs poorly and forces you to spend money on higher utility bills or unanticipated repair costs. Here are some of the prime mistakes when you start shopping for your new unit.

Not Matching the Unit to Your Household

Every residential building layout calls for a specific amount of heating and cooling output. For this reason, air conditioner and furnace manufacturers create product lines geared to suit a wide range of needs. Before you make a purchase, you must know the AC and/or furnace size that will cool or heat your home properly. If the unit you buy is too large or too small, you can run into serious issues that include constantly unpleasant indoor temperatures, a jump in the amount of money you pay for monthly utilities and unexpected AC or furnace breakdowns.

Being Too Frugal at Purchase Time

No one wants to spend money needlessly, especially when it comes to something as costly as a new air conditioner or furnace. However, if you put the purchase price of a furnace or AC before all other considerations, you may be doing yourself a major disservice. That’s because the cheapest available units may have significant reliability and efficiency issues that put you on the hook for frequent repairs and much higher utility bills.

Putting Efficiency Low on Your Priorities List

The most efficient air conditioners and furnaces available today use far less power than the least efficient. As a rule, less efficient units have a notably smaller purchase price than higher-efficiency units. This fact might encourage you to place efficiency low on your list of buying priorities. However, if you spend the extra cash on a more efficient AC or furnace today, the savings in utility costs you receive over time may actually exceed any amount of money you save by opting for a less efficient unit at purchase time.

Not Giving Due Consideration to Your Contractor

Contractors have a crucial impact on the process of purchasing and installing a new air conditioner or furnace. While a reputable, cost-conscious provider can help make this process go smoothly, a provider who’s disreputable or doesn’t pay close attention to the bottom line can complicate matters to no end. Important contractor-related steps include verifying the professional reputation of all potential candidates, comparing the prices offered by at least two reputable providers and finalizing all agreed-upon work with a written contract.
