Room Air conditioning

1. Set yours conditioners thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. And don’t set your thermostat at a slighter setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense

2 Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home better and will remove more moisture from the air because of slower air movement through the cooling equipment. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing electricity use.

Air conditioning tips

1. try to yours thermostat between 72°F and 78°F. Each degree setting below 78°F will increase your energy consumption by approximately 8%. As you can see, that can add up to a lot of money over a year.

2. Inspect and clean both the indoor and outdoor AC/Heating coils. The indoor coil in your air conditioner acts as a magnet for dust because it is constantly wet during the cooling season. Dirt build-up on the indoor coil is the single most common cause of poor efficiency. The outdoor coil must also be checked periodically for dirt build-up and cleaned if necessary.

3. Check the refrigerant charge. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly. You may need a service contractor to check the fluid and adjust it appropriately.

4 Use bath and kitchen fans sparsely when you are running the air conditioning system.

Reduce the cooling load by using cost-effective conservation measures. For example, effectively shade east and west windows. When possible, delay heat-generating activities, such as baking, until the evening on hot days.

What's the Right Air Conditioning Type for you?

This is what people most commonly think of when they speak of wanting air conditioning. Split central air allows you to place the noisy portion or your cooling unit outside where it will be less noticeable. Split central air requires that your house have ducting to the various rooms in your home (usually the same ducting you use for your central heat). Central air allows you to cool all parts of a house evenly and quietly.

For those on a budget or if you just have a room that refuses to cool as well as the rest of the house a portable unit is an economical option. It will be noisier, allow some warm outside air into the house, and have a more limited cooling area but it will make a significant difference on the temperature of your room.
Also known as "swamp coolers" evaporation coolers pull air through damp pads cooling it as the air evaporates the water that becomes attached to it.

What’s involved with Servicing a Central Heating System?

A large percentage of suburban American homes have central HVAC (heating and air conditioning systems) that use duct work to vent warm or cool air throughout the home as needed. Most of these central systems burn either oil or gas, but the basic service procedures are similar and should get an annual checkup.

Failing to perform a yearly cleaning and inspection can reduce the life of your heating system and reduce its efficiency or worse; a blocked HVAC system could cause carbon monoxide to be pumped into your home, creating unsafe living conditions, or your system could fail altogether.

Most central HVAC systems have fairly standard components and if you are handy with basic tools and home maintenance tasks you can do at least part of the work yourself.
