Air Conditioning

While air conditioners require the use of some different components in your heating and cooling system, the three most important factors you should evaluate are essentially the same: quality, efficiency, and comfort features.

Quality –

When you purchase a new car, the quality of it helps determine how well it will perform and for how long. An air conditioner is really no different. Purchasing a brand name that has a reputation for quality and reliability can save you headaches and extra expense down the road. New Welsch air conditioners and split systems, for example, undergo 34 quality tests and checks during production, with more than 20 of these being performed on every unit – not just on random samples. Plus, we back every air conditioner in writing, with a 5-year limited warranty on the compressor (some deluxe models have 10) and from one to ten years(depending upon the model) limited warranty on the parts.

Efficiency –

Cooling efficiency for air conditioners is indicated by a SEER (Seasonal Energy Efficiency Ratio) rating, which tells you how efficiently the unit uses electricity. In general, the higher the SEER, the less electricity the unit will use to cool your home. The government mandated minimum efficiency for air conditioners is 13.0 SEER. However we have air conditioners today which have SEER ratings that range from 13.0 to over 18. Usually, the higher the efficiency, the more expensive the unit. Your Welsch professional can use cooling data from our area to help you determine about how long it will take you to recover the additional cost in energy savings. Of course, after the payback, you continue to save on your energy bills for the life of the system. One other point to keep in mind is that your air conditioner is a “split system,” which means that there is an outdoor unit (condenser) and an indoor unit (coil). If you are replacing an existing system, both units should be replaced to make sure your new condensing unit gives you optimal performance, efficiency and comfort.

Comfort Features –

Some air conditioners offer additional features that provide greater comfort (as well as additional energy savings). Two-speed units can run on low speed (using 50% of the energy) up to 80% of the time, so they operate more quietly and run for longer periods of time than single-speed models. Longer operating periods translate into fewer on/off cycles, fewer drafts and much smaller temperature swings — only two or three degrees instead of the four-degree swings common with single-speed units. Plus, better air circulation helps prevent air “stratification” – warm air rising to the ceiling and cold air settling on the floor. In short, you get consistent, even cooling throughout your home. If you purchase a multi-speed or variable speed furnace or fan coil with your unit, you will enhance both the comfort and the efficiency of your air conditioning system even further.

Air Filtration

If you thought air pollution was just an outdoor concern, think again. The particles you see in a beam of afternoon sunlight streaming through the window only represent about 1% of the millions of airborne contaminants in your indoor air. Most standard fiber glass-mesh furnace filters only trap about 15% of these particles, leaving the other 85% to pollute your air, your furnishings, even your lungs.

Clearing The Air –

A mechanical air cleaner has a heavy-duty media filter that can trap up to 28 times as many particles as a standard fiber glass filter, including animal dander and plant spores… These units can remove up to 99% of the air borne dust and dirt particles. Air cleaners can improve your health, keep your entire home cleaner, protect your valuable investments and save you the time and aggravation of constant dusting.

Heating Systems

Considering a new furnace? Here are some things to consider when shopping for a new furnace or heating system.

1. Quality –

When you buy a new car, the quality of it helps determine how well it will perform and for how long. A furnace is really no different. Purchasing a brand name that has a reputation for quality and reliability can save you headaches and extra expense down the road.

New furnaces by Welsch, for example, undergo a rigorous series of quality tests and checks during production, with many of the tests being performed on every unit – not just on random samples. Plus, we back every furnace in writing, with a written warranty on the heat exchanger (the heart of the furnace) and  the entire unit.

2. Efficiency –

A furnace’s efficiency rating, or AFUE (Annual Fuel Utilization Efficiency), tells you how efficiently the furnace uses fuel. In general, the higher the efficiency, the less fuel the furnace will use to heat your home. The government established minimum AFUE rating for furnaces is 80%. In contrast, many furnaces manufactured before 1992 had AFUE ratings as low as 60%.

High-efficiency furnaces, also called condensing or sealed combustion furnaces, offer AFUE ratings from 90% to  98%. See the Home Page of our website for information regarding the fact that these High-Efficiency furnaces will become standard by May 2013.

Although the higher efficiency may result in a more expensive furnace, Welsch professionals can use heating data from our area to help determine about how long it will take you to recover the additional cost in energy savings. Of course, after the payback, you continue to save on your energy bills for the life of the system.

3. Comfort Features –

Many furnaces offer additional features that provide greater comfort (as well as additional energy savings). Two-speed and variable speed furnaces can run on lower speeds up to 90% of the time, so they operate more quietly and run for longer periods of time than single-speed furnaces. Longer operating periods translate into fewer on/off cycles, fewer drafts and much smaller temperature swings — only one or two degrees instead of the four-degree swings common with single-speed furnaces. Plus, better air circulation helps prevent air “stratification” – warm air rising to the ceiling and cold air settling on the floor. In short, you get consistent, even heat throughout your home.

The variable speed furnaces provide the ultimate combination of comfort, efficiency and quiet performance. In addition to their other benefits, they offer “smart” motors that can monitor your home’s comfort needs and automatically adjust the volume and speed of air to provide the most efficient heating or cooling. They offer added electrical efficiency as well: the “smart” fan motors on some models sold by Welsch use less electricity than a 100-watt light bulb. They operate so efficiently that they can actually increase the efficiency rating of your central air conditioning system and offer you added energy savings when you use continuous fan operation in any season.

Humidifiers

Controlling humidity can not only affect how comfortable you feel, it can actually save you money on your monthly energy bills.

Our bodies “feel” heat as a combination of temperature and humidity. In other words, the more humid the air, the warmer it feels. So if you add humidity to dry, heated air in the winter with a Welsch humidifier, you can set your thermostat lower and still be comfortable – while you save money on your utility bills.

A humidifier can also help prevent dry, cracked skin, make it easier to breathe, protect your woodwork and reduce static electricity. It can even make you less susceptible to sore throats and winter colds.

Humidifiers operate on the basis of a simple concept. Air heated by your furnace or heat pump passes through a ceramic-coated pad in your humidifier, called an evaporator pad. The air absorbs moisture from the water-soaked pad and becomes water vapor that humidifies the heated air that is circulated throughout your home. Most humidifiers feature an adjustable humidistat so you can control the exact amount of moisture in the air. The proper amount of moisture depends on the outdoor temperature and other factors; your owner’s manual has recommendations for the best settings for your conditions.

Thermostats

Thermostats help your heating and cooling equipment maintain the optimal temperature setting with the utmost energy efficiency. Today’s electronic models are a vast departure from earlier mechanical styles. Microprocessors allow you to program your home temperatures to suit your lifestyle, so you can keep things comfortable while you’re home and automatically set back your temperatures to save energy when you’re away or sleeping.

Electronic thermostats work in much the same way as older, manual thermostats did. The microprocessor inside compares the thermometer reading of a room’s temperature to the desired temperature you select. Then, it gives start and stop commands to the heating or cooling system to bring the temperature to a level that makes you comfortable.

Programmable thermostats basically work the same way, but they are far more convenient. Once you program the thermostat to customize the system’s operation to fit your lifestyle and schedule, all you have to do is relax and let it do all the work. You simply program into its memory the temperatures you need, at what time of the day, to stay comfortable and save energy all season. You only need to program it once – until the season or your lifestyle changes.

The most important way that a programmable thermostat saves energy is in its setback feature. When you don’t need a normal level of heating or cooling, you can program the thermostat to set the temperature back until the next pre-programmed time when you want normal temperatures. Programming temperatures around 63 F on cold winter nights, when you’re snuggled under blankets, can help you save as much as 15% on your heating costs. You can save even more by programming your system to “setback” the temperature when your family is away at work, at school, or on vacation.
