Instead of adding more insulation, you should consider adding a radiant barrier system. This will have a greater effect on your cooling bills because it reflects heat away from the attic before it can reach the insulation and ceiling below. Without a radiant barrier, your roof radiates solar-generated heat to the insulation and, if they are mounted in the attic, your air conditioning ducts below it.

Either loose fill (typically fiberglass or cellulose) or batt insulation (usually fiberglass) will work well. Batts are easier to install yourself, while many contractors find loose fill easier and less expensive to install.

If you wish, you can insulate the walls of a box cooker with various substances. Fiberglass or Styrofoam is usually not recommended since they give off ill-smelling gases as they heat up. Natural substances such as cotton, wool, feathers, or even crumpled newspapers work well. Many people, however, leave the walls empty of any stuffing, preferring instead to place a piece of foiled cardboard as a baffle inside the wall airspace. This makes a lighter cooker and seems to be adequate.

Most homeowners find it easiest to use batt insulation. Always use unfaced batts, as the paper of foil vapor retarder can trap water vapor in the original insulation, causing moisture problems. If possible, install the new insulation perpendicular to the attic floor joists to reduce heat loss through the joists. Loose fiberglass or cellulose can also be used, by pouring it and leveling it with a board or other implement.

Yes. Awnings conserve energy by shading windows and reducing indoor temperatures. Studies by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRE) have shown that awnings on windows and patio doors can reduce inside temperatures by as much as 8-15 degrees, depending on the exposure of the window, and the style and method of attaching the awning.

McCullough Heating & Air Conditioning has been serving customers in Central Texas since 1977. We are a family-owned and operated company that takes pride in the high quality products and services we offer our customers, many of which have been using us for their home comfort needs for many years.

RenewAire systems work very well with air-conditioning - much better than sensible-only heat exchangers. As in the winter, if you keep your house closed up tight, (as you should when air-conditioning), indoor air quality will suffer. The only real difference is that air-conditioning systems do have some moisture-removal capability, unlike heating systems. Exactly how much water the air-conditioner will remove depends on how it is set up.

Requests can be made by telephone, e-mail, or fax (578-5597). Provide the following information: Name, phone number, building and room/s, date and times the a/c needs to be on. A three day notification is required to ensure requests are properly scheduled.

Send a letter to Facility Services-Energy Services requesting the change. Please include the building and room numbers requiring the change, the requested hours, the reason why the change is requested, and the name of a contact person to discuss the change.

The original Air Probe Sanitizer is made of extruded aluminum and all stainless steel connectors. It can be manufactured to fit any size air conditioner. There is no HVAC system which cannot use the original Air Probe Sanitizer. (top)

If you have a question regarding your home or commercial building we will be more than happy to have our technical representative recommend the proper materials and procedures for your situation. Use our Feedback form and tell us a little about, where your building is located, the type of construction and the materials on the interior and exterior walls.

NO At the conception of Hendel's Air Conditioning Joe and Linda Hendel's vowed to offer their customers the best value. Maintenance agreements are usually one sided in favor of the companies that offer them. Caution: telephone solicitors may offer a (foot in the door) low price maintenance service. When the technician arrives they all try to sell the easy to change part a contactor and clean the coil for approximately $260.00.

Forced air and heat will be supplied to the units from individual high-efficiency electric heat pumps.

It will depend on the situation. By and large, for lofts we recommend cellulose fibre, made from recycled fireproofed newsprint. Warmcel, made from recycled newspaper, is available from us by mail order. Another environmentally-friendly option is Sheep's Wool. For more information about the various types of insulation material and uses, see our Insulation Tipsheet.

Cellulose insulation has been shown to reduce air-leakage through wall and ceilings of buildings. Colorado University found cellulose at least 36 percent better than fiber glass in tightening buildings, which resulted in a 26%+ overall improvement in energy efficiency. Considerable research at the US DOE Oak Ridge National Laboratory shows cellulose insulation is not as subject to convective heat loss.

If you want radiant heat and air conditioning, we recommend installing a distribution system for air conditioning within the ceiling and radiant heat tubing within the floor. Combining a forced hot air heating system and an air conditioning system utilizing floor registers is a less comfortable, dustier, and more expensive alternative than using two separate systems.

The air conditioning term "ton" equates to 12,000 BTUH (British Thermal Units per Hour). A 3 ton air conditioner is capable of removing a combined sensible and latent (humidity) load of 36,000 BTUH per hour (3 x 12,000).

Air conditioning is the control of temperature, humidity, air movement, and the quality of air in a room. Basically, we need air conditioned space is to maintain the indoor conditions in comfortable manner and control or improve the conditions of an industrial process so that its quality of the products is enhanced.
