Here's an interesting system from HydroPoint Data Systems.
 
Using data from NOAA satellites and other sources, the WeatherTrak ET Plus irrigation controller adjusts irrigation output as the weather changes, ensuring watering only takes place when needed and eliminating overwatering. The controller also can be set for specific plant types, soil, slope, and sprinkler type to help quickly optimize watering schedules.

Watering would be pretty consistent here in the Phoenix area with this system!  But it would still be nice to know that when it does rain, like last night, that my plants wouldn't be watering twice if I had this system installed.

This is a great post, especially during these hot summer months in Phoenix.  When remodeling, one of the most important things to improve is the HVAC.  Why upgrade?  To save money on utility cost in the long run, of course, and well, it just makes sense to make this important change so that you can truly appreciate your new remodel. 

Carrier has recently come out with a unit featuring Greenspeed intelligence shown here.  The company’s latest Infinity heat pump offers an industry leading HSPF heating efficiency rating of up to 13 along with cooling efficiency up to 20 SEER. According to the firm, the unit’s variable-speed scroll compressor provides consistent indoor temperatures while conserving energy. The line includes capacities from 2 to 5 tons.

If you really want to enjoy all the new renovations in your remodeled home you'll really want to consider upgrading that old unit.  You won't regret it!
