Comments Off on AC Tips from W.Williams an Armstrong Air Professional
August 3
Armstrong Air dealers have years of expertise in heating and cooling. Their knowledge can help you save money in many ways, from proper insulation to optimizing the performance of heating and cooling equipment.


  • Proper home insulation is the most important part in conserving energy and keeping your utility bills lower. For average homes, use the below as a guide. Houses located in cold temperatures may need additional insulation to promote desired energy conservation.
    • Ceilings: R-30 (10″) Thermal resistance
    • Exterior walls, floors (over unheated areas): R-11 (3-1/2″) Thermal resistance
  • When using your heating or cooling system, keep all windows and doors closed.
  • Windows allow heat to enter the home in summer and escape the home in winter, but heat transfer can be cut significantly—up to 40% to 50%—by switching to double-glazed windows. These windows have a sealed air space between the two panes of glass.
  • Get metal-frame or wood-frame storm windows for your home. That extra layer of glass and air cuts heat transfer tremendously, even if your single-glazed windows are high quality.
  • All entrance doors and windows should have weather-stripping and caulking. Also, if your home has small areas where outside air can filter in, plug them with plastic, caulking or weather-stripping.
  • Fireplaces should have tight-fitting dampers that can be shut when not in use.

Energy Efficiency

  • Humidifiers can help conserve heating costs in wintertime because moist air feels warmer and you can set your thermostat at a lower temperature setting.
  • Take advantage of a programmable thermostat which allows you to adjust indoor temperatures to your schedule. While away from the house, the system (heating or cooling) can be set to run less frequently, saving energy and money.
  • When going away on a trip, always adjust the temperature so the heating/cooling system will run less often. You may not want to turn the system completely off because heat often leads to odors or unwanted humidity that can be hard on furniture or other household items. Likewise, allowing your house to get too cold could lead to burst water pipes from freezing conditions.

Heating System

  • Have your thermostat mounted on an internal wall, away from windows and doors.
  • If you’re expecting a large group of people, lower the thermostat just a couple of degrees. You’ll save on heating bills and have a more comfortable environment.
  • Set the thermostat as low as comfort permits. Each degree over 68° can add 3% to the amount of energy needed for heating.
  • Have your ductwork cleaned regularly by a professional.

Cooling System

  • Make sure your attic is well ventilated. Heat rises, and having larger vents can help relieve heat buildup.
  • If renovating a roof or building a new home, consider lighter-colored shingles to reflect the sun’s light and heat.
  • Don’t place heat-producing home devices such as televisions, computers or lamps near or under your thermostat.
  • Set your temperature as high as comfort will permit.
  • Consider installing awnings, shades or shutters over windows that are exposed to direct sunlight.
  • Keep kitchen and bath exhaust fan use to a minimum during summer months.
  • Draw blinds or drapes during peak daytime temperatures.
  • In moderate weather, consider opening windows instead of turning on the A/C.

Comments Off on Why Ductless with W.Williams & Mitsubishi
may1   Are you looking for an efficient, low-cost solution to satisfy room temperature troubles? No matter what size space you’re trying to heat or cool, discover energy efficient savings, eco-friendly solutions, while keeping the temperature just right inside your home. Imagine the possibilities with a ductless temperature controlled system. 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 is going. 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.

Comments Off on What is a Mini Split Air Conditioner?
April3     The central heating and cooling systems that are traditionally used in homes are called split systems because they typically have indoor and outdoor components. A mini split air conditioner also has indoor and outdoor components, but it takes up a lot less space than traditional heating and cooling systems. Another key difference is that it doesn't rely on ducts to deliver heated and cooled air.

How Do Mini Split Air Conditioners Work?

Mini split air conditioners work similarly to other types of air conditioners in that they compress and expand refrigerant to pull away heat and moisture from the air. There are some pretty significant differences between mini split air conditioners and other types of air conditioners, and they include:
  • Heat Pumps - How are ductless air conditioners, or mini split air conditioners, capable of heating and cooling without needing large indoor and outdoor units? The secret lies in energy-efficient heat pumps. They take advantage of heat's tendency to move from warm areas to cool areas. In doing so, they are capable of heating and cooling while using a lot less energy.
  • Connections - As with a traditional heating and cooling system, mini split systems have indoor and outdoor components. In this case, however, the indoor and outdoor units are connected by suction lines, which draw away condensate, refrigerant lines, which facilitate the transfer of warm air, and power lines, which keep everything humming along.
  • Indoor Units - With a mini split air conditioner, outdoor units are mounted on outside walls. There are also compact indoor units, which may be mounted on floors, ceilings or high up on walls. These units have blowers that deliver heated and cooled air to a specific area. You can't understand how mini split air conditioners work without understanding that no ducts are involved at all.

Comments Off on How Does Ductless Air Conditioning Work?
April2         Ductless split systems provide targeted heating and cooling comfort when conventional central HVAC equipment is too costly or impractical to install. Widely adopted in Europe and Southeast Asia, ductless technology continues to gain popularity in the U.S. as consumers and businesses look for cost-effective alternatives to window units, PTACs (packaged terminal air conditioners) and inefficient ducted systems.

Basic Components of a Ductless System

So, how does ductless air conditioning work? In many respects, a ductless mini split operates in a similar manner to its ducted counterpart. In the refrigeration cycle, low-pressure gas is transformed into high-pressure gas by the action of a compressor. The heat is dissipated into the outdoors by the action of a forced air fan. The refrigerant then becomes a high-pressure liquid, and it is again changed into a low-pressure liquid by a metering device at the evaporator coil. Heat energy from the indoor air is absorbed by the refrigerant, and the resulting cooler air is pushed into the living area by the internal blower. The resulting low-pressure gas is moved through the suction line back to compressor, and the cycle is repeated again. There are two main elements in a ductless split system installation:

Outdoor Unit

The outdoor condensing unit houses three primary components including:
  • The Compressor: The compressor is the heart of any air conditioning system. It is also the most expensive individual part. The device condenses low-pressure gas into high-pressure gas, so the thermal heat transfer process is completed more efficiently.
  • Condensing Coil: A lattice-like structure comprised of numerous aluminum fins, the condensing coil cycles hot refrigerant and accommodates its conversion from a high-pressure gas to a high-pressure liquid.
  • The Fan: The fan draws air through the condensing coil and helps dissipate the stored heat energy into the outdoor environment.

Indoor Unit

How do ductless air conditioners work? It is important to recognize the distinct advantages of spilt system indoor fan coil units. Conventional central air conditioners employ a single air handler, blower and evaporator coil, which is usually installed in a garage or equipment closet. A complex air distribution network provides an avenue for the delivery of conditioned air into each room of the building from a single point of origin. Unfortunately, ductwork is often inefficient, restrictive, dirty, leaky and noisy. Ductless indoor units include a fan and evaporator coil in the same enclosure. Each unit provides point of use air conditioning wherever it is installed. Stylish cabinets are available in wall mount, duct mount and ceiling cassette varieties. Whether used in single or multiple zone configurations, the indoor units can be strategically positioned to heat and cool one room or an entire building. The versatility and convenience of ductless technology completely eliminates the need for inefficient ductwork. When comparing ductless ac vs. central ac vs. window unit, ductless split systems are quieter, more efficient and offer greater levels of comfort.

Mini-Split versus Multi-Split

In multi-room applications, does ductless AC work? In fact, ductless air conditioners are an excellent choice for both single and multi-zone areas. Systems can be installed in a variety of different configurations based on the following two platforms: Mini-Split: A mini split includes a single indoor fan coil and outdoor condenser. This combination is especially effective for cooling an individual room that has limited load requirements. If there is sufficient space to set multiple condensing units outdoors, several systems can be used in tandem to provide cooling for an entire building. This type of installation provides a separate temperature control for each unit. If there is a malfunction in one system, the rest will continue to provide conditioned air to the unaffected areas. Multi-Split: A multi-split system employs one condensing unit that is connected to several indoor air handlers. In this configuration, an indoor unit is selected and equipped with a thermostat. When there is a call for cooling, all of the units are activated simultaneously. This configuration is cost effective but should only be used in buildings where each room has a similar cooling load. For true zoning in a multi-split application, a single condensing unit must be equipped with separate compressor circuits that are piped to each individual air handler. Every zone is controlled by a different thermostat, so the occupants can tailor the temperature to their individual preference. A Mitsubishi air conditioner designed for multi-split operation can include up to eight different zones.

Ductless Heat Pump How it Works

In the cooling mode, a ductless heat pump operates in essentially the same way as an air conditioner. The inclusion of a reversing valve allows the refrigerant to flow in either direction, which provides both heating and cooling from a single ductless system. When considering the installation of a ductless heat pump, it is important to understand the relationship between heating efficiency and the outdoor ambient temperature. In general, a heat pump operates most effectively in mild climates that rarely reach the freezing point. An electric heat strip can be installed to provide supplemental heat when necessary.

Where Ductless is needed

Ductless air conditioners and heat pumps offer exceptional flexibility and can be modified to fit numerous applications. In addition to existing buildings, mini splits are appearing more frequently in new construction where the low profile of ductless equipment is very compatible with modern architectural design.

An Air Conditioner Small Enough For:

  • Server Rooms
  • Condos
  • Basements
  • Garages
  • Attics
  • Buildings Requiring Supplemental Cooling

An Air Conditioner Quiet Enough For:

  • Hospitals
  • Churches
  • Bedrooms
  • Recording Studios
  • Meeting Rooms

An Air Conditioner Powerful Enough For:

  • Office Buildings
  • Multi-Tenant Buildings
  • High Rise Buildings
  • Hotels
  • Data Centers

High Efficiency Perfect for Everyone

Ductless split systems offer exceptional versatility, low noise and enhanced levels of comfort. Through the use of exclusive inverter technology, ductless air conditioners have the highest SEER ratings in the industry. Many consumers ask, “How much does ductless AC cost?” By eliminating the need for an air distribution network, a ductless air conditioner saves substantially on labor and installation costs. Mitsubishi contractors invite you to explore the many benefits that an efficient ductless split system can provide.
