Unit Size
What's the problem?
One of the most frequently asked questions is, "What is the right sized comfort system for my house?" Your house may be too cold or hot at times, it may have uneven temperatures from room to room. The comfort system may be too noisey; the humidity level in your home may be too high. An incorrectly sized system will cause these and many other undesirable indoor problems. Although some of these issues can be attributed to improperly sized ductwork, often a correctly sized comfort system will solve these problems. The system that your builder installed when the home was new or the one that was put on before you moved into your home may have always been the wrong size and nobody even knew it.
How Can We Solve It?
This issue is easily addressed by having a HEAT LOAD CALCULATION done on your home. Your home is measured for floor space, window size and type, insulation values, roof color, and other factors. These measurements are entered into an engineering program which computes how much cooling & heating are required for your home at a specified outside air temperature and desired indoor temperature. The program will address all of these factors along with any internal heat load such as a big screen TV or a gourmet kitchen. The J.R Perkins Company is currently using and is certified in 2 different programs for heat loads.
1. The total load in the state of Arizona is calculated on "sensible load only" and is measured in BTU's (British thermal units). Once the BTU's are calculated, a comfort system that can provide that amount of cooling at an outside temperature of 108 degrees is selected.
2. A "gross load" calculation is used when sizing your new comfort system. Often times this load is done free of charge when a customer is seriously considering purchasing a new machine. A room-by-room can take several hours to do properly and can cost hundreds of dollars. This detailed heat load calculation also allows for a very precise ductwork design as well. A quick look at the existing ductwork compared to the heat load will very quickly establish what ductwork needs to be repaired for a better opertating comfort system.
BUT WAIT... There's Still A Problem
Even though we have now calculated the correct system for your home, you now have an oversized system for every temperature other than 108 degrees. That is right, your system is now too big for almost 80% of the time, and in time this oversized system will cost you more to operate and repair as a result.
Don't Worry, there is a solution!
There are indoor comfort systems that can adjust to your constantly changing home conditions.

Want a Heat Load Calculation done to your home?
You can email the square footage of home, wall dimensions, window size, style, location, roof color, attic insulation value, wall insulation value, and wall orientation (direction). Give us that information on our contact us page, along with your personal contact information and we can have one done for you normally within 2 working days.
Cost for a Heat Load Calculation is ONLY $25.00
Always Remember
Turn off your system at the breaker or unplug it so there is no risk of inadvertently shorting out the low voltage control circuit. Also, make sure you put all the wires and jumper wires back to the same terminals on the new thermostat. I find it is always best to snip the wires off close to the old thermostat so I can always us it as a guide.
