What portion of your annual electric bill is for air conditioning? In the Phoenix area, cooling accounts for 41% of energy needs. (Source: Calculated energy costs based on energy analysis criteria published by the American Society of Heating, Refrigerating and Air-Conditioning, Engineers, Inc.

AC efficiency. When the electric company, APS and HVAC contractors discuss "efficiency," what are they talking about?? Air conditioning in the Phoenix area is a large portion of a home owner's electric bill. S.E.E.R. stands for Seasonal Energy Efficiency Ratio. The higher the rating, the more energy efficient the air conditioning unit (or heat pump unit) and the lower your electric bill will be. Starting January 1, 2015, the minimum efficiency for Arizona is 14 S.E.E.R.

Privacy fencing--a good thing or not a good thing? While servicing one air conditioning unit last week, I found that the A/C privacy wall for the outdoor air condenser did not allow proper air requirements for the unit. A minimum of 12 inches from the sides of the outdoor AC unit is the manufacturers' specification. The air conditioning condenser needs to have adequate space from any object in order to achieve proper air flow and thus propert functioning of the outdoor unit. When the privacy walls are too close, the air is "short cycling" and causing the unit to work too hard. If a unit does not get enough fresh air, it will shorten its working life.

Last week, the question was raised "Why are some rooms at the thermostat temp setting and other rooms are just not as warm or cold." The Goodyear home under discussion has a forced air HVAC system. Assuming that the HVAC system was sized correctly for the size and type of the house, ductwork layout is most likely the reason sections of the house have more or less air flow, thus cold/hot spots in certain areas of the house.

The layout and design of the ductwork is very important. The total load (amount of cooling or heating needed for the entire house) needs to be distributed correctly to the specific rooms of the house so that these cold/hot spots do not occur.

Each room needs to be calculated for its specific cooling/heating needs and the ductwork needs to be sized and installed accordingly.

At Pebble Creek Air, we have been working on setting up our different accounts and we have been successful! We sell and install Carrier equipment as well as American Standard equipment. Some would ask, "Why do you have the two different product lines?"

When you think about air conditioning and heating your home, there is more involved than just picking a size that is BIG enough to work. Oversized new equipment can actually cost you money, not save you money! Having the two different product lines gives more flexibility to meet the exact air conditioning and heating needs specific to your home. A comfortable climate is easier to obtain with the flexibility that Pebble Creek Air Conditioning & Heating LLC offers.
