A cooling degree day is used during warm weather to estimate the required energy for cooling indoor air to a comfortable temperature. One cooling degree day occurs for each degree a day’s average air temperature is above 65°F. Large cooling degree day values imply warm weather and, thus, a large energy demand for cooling. This Climate Prediction Center page has more about degree days, as does this National Climatic Data Center page.

Many heating and cooling professionals are not aware of the benefits of Powerzoning because they're not trained to understand how your home's indoor environment works. Most HVAC professionals are trained to install a properly sized (BTU) system and run ducts appropriately, and they do a very good job of this, but their understanding of how the system can get the best results for a homeowner can be limited.

The most common complaint we hear, is that one area of a house is hotter or cooler than another area. This is usually caused by poorly sized ductwork. This can only solved by costly heat load calculations and redoing your entire duct system. A more simple solution is to take advantage of two-stage heating and cooling. When you have single stage heating and cooling you are getting 100% of the heating or cooling every time the thermostat calls for it.

One of the things that makes a heat pump so versatile is its ability to be both a heating and cooling system in one. You can change from one mode to another with a simple flick of a switch on your indoor thermostat. In the cooling mode, a geothermal heat pump takes heat from indoors and transfers it to the cooler earth through a closed loop underground system or groundwater wells.

In winter, the system extracts heat from the ground, which is converted to warm air (or water) for space heating, water heating or radiant floor heating. In summer, the compressor puts heat from the building into the loop fluid, and this heat is 'rejected' into the ground outside to provide cooling for the structure.

The Airomax system will deliberately cause "air turbulence" to occur in your shop. The turbulence is required to keep smoke, dust, and over-spray particles suspended until they are captured in the filters. The turbulence prevents stratification of heated or cooled air and equalizes the air temperature at the floor and ceiling. Usually, the heating and cooling system will cycle less frequently when an Airomax system is in operation. This reduces the cost of heating and cooling air.

Geothermal is a version of electric heating and cooling pulling heat from the mass of earth surrounding your house in the winter and moving heat from your house back to the earth in summer. Tapping hot water and using geothermal systems for air conditioning can make economic sense. We will be happy to explore use of geothermal energy with you in our Improvement Analysis.

Sizing your system is very important. In today’s economy of high fuel costs, it is especially important to make sure you are getting the most efficient system for your square footage – not over, not under. We can help you pick the right size heating or cooling system for your situation. Our knowledgeable staff will assist you in comparing gas furnaces and air conditioning systems. They know the furnace ratings and everything you need to know to make a well-informed decisions.

Because RenewAire recovers most of the heat energy in the exhaust air (in the winter), this is the least expensive kind of ventilation system to operate. RenewAire is also much less expensive to operate than a dehumidifier sized to accomplish a similar amount of wintertime moisture removal. In fact, most people report little or no impact on their heating or cooling bill, but this can vary depending on many factors.

Look for contractors that are N.A.T.E. certified, and factory trained and certified. They should do a ???Manual J??? heat load analysis to properly size any new equipment. Make sure they are licensed, bonded and insured, and ask for proof of this. Be sure they permit all applicable work. Check their record with the state Attorney General???s office, Better Business Bureau and referral services like ???Angie???s List???.

With the system set to heat, when the set point temperature is raised or lowered past the room temperature, the thermostat will make a soft click sound within about 5 seconds. Usually the sound indicates correct thermostat operation. If the heat does not come on after raising the temperature and hearing the click, check the fuses or breakers, make sure the furnace is switched on, and verify the blower compartment door is closed properly.

The affect on your climate control bill is minimal, based on the fact that the E·Z Breathe® draws air from the very lowest part of the home. This air is always the coldest air in the home to begin with, and due to its damp nature it is also the hardest to heat. Once in operation the E·Z Breathe® moves the colder air out, and since dry air is easier to heat than damp air, your heating system does not work as hard to maintain the desired temperature.

Yes. A GSHP can be a combination heating/cooling and hot water heating system. You can change from one mode to another with a simple flick on your indoor thermostat. Using a desuperheater, some GSHPs can save you up to 50% on your water-heating bill by preheating tank water.

I am working in energy sector. I would like to have an 'Questionnaire' on 'Energy Auditing' and 'Remote Metering'. Please help me. include the manufacturing process as well as facility concerns. Are there courses or certifications dealing with this issue? Can you recommend some books, pamphlets, etc.? Any ideas on societies or publications? Thoughts on checklists, software, etc., etc.

NCI-certified contractor will first ask you questions about the system, what you like and don't like about it, problem areas, air quality concerns, health issues, etc. He should then perform some preliminary testing to determine the condition of your system, the biggest problem areas, and so forth. This is generally performed using several instruments including a manometer which measures your systems pressure, much like a doctor checks blood pressure.

Adjustments in temperature may take up to several hours to be felt. In many instances, the systems are working for an entire building, not just a single office or classroom. Changing the thermostat does not cause an instantaneous change in temperature. If you do call in with a complaint of being too hot or too cold, please be patient while the adjustment takes effect. For temperature problems affecting critical research and/or animal welfare, please call 8-7208.

The fan in the heating/cooling system should be set in the 'always on' position, instead of the auto mode. The EnviroSept can't clean the air and reduce dust if the fan is not running. Circulating the air constantly provides the added benefit of elininating hot and cold spots inside the home.

Keep your thermostat at a constant temperature, the recommended temperature is 78?, even when no one is home. Check the outside condensing unit regularly for any grass clippings or leaves stuck to the coil. If it is dirty:

No. Just like automobiles, there are many different selections within each size and brand. These selections range from standard efficient units to super high efficient units. Warranties range from one year parts and labor up to ten years parts and labor. Units can heat with gas, electric, heat pumps, or hot water.

Our log homes are warm in the winter and cool in the summer. The main reason for this is the size of the logs. Unlike conventional construction where “R-value” is incorporated in the structure using insulation, in a log home the insulation comes from the thermal mass of the log. For instance, a smaller log has considerably less thermal mass than a 12”-16” log.

Twenty percent of the average energy demand in a residential home is for water heating, and most units include a component to heat water for potable or sanitary use. Heat pumps can also be used to dehumidify indoor swimming pool areas, by controlling condensation with a minimum of ventilation and using the recovered heat in the main heating process.

Each heat pump unit can perform only one function at a time, but a larger building (with more than one unit) can provide heating to one spot and cooling to another. This is a common application in schools and other institutional facilities, which have a diverse load.

First check to ensure there is electricity to the unit. If not cooling, there is a thermostat on the back grill. Turn slightly to the right and listen for the compressor to start. If the cooler has a hot side, check the back to be sure the on/off switch is on.
