AboutCraig HVAC Expert Expertise I have been in the HVAC field for the past 12+ years. I can help with most HVAC questions. I work on commerical buildings for the most part, and have yet to find anything I could not troubleshoot and repair, when repairable. I work on small 1 ton units to a 2500 ton chiller. Troubleshoot air flow, elect, and control problems. I attend regular classes to keep up with the latest and greatest.
Experience I have work in the HVAC trade for the past sixteen years. I work on commerical sites, hospitals, gov't buildings. I can troubleshoot just about anything in the HVAC business.

Question i've just had a contractor install a split system: gas furnace and refrig pad
mount unit. we had some disagreement when he put it in...i felt it did not
require more than 3 tons, and he insisted on 4 1/2. there is a second 2t heat
pump to handle a smaller portion of the house. the house is a rebuilt, one-
story, 2400 sf, el paso, tx w/ insulation upgrade, 16 seer equipment, and new
roof w/ continuous ridge vent. the 4 1/2 t unit comes on every 15 minutes
and runs for 7-10 minutes then shuts off. when it runs, there is a steady
stream of water "running" out of the condensate drain line...more than i have
ever seen in a similar installation. my experience in the past has been that
when units are grossly overdesigned, they cycle. which not only effects the
electric bill, but wears the equipment out. not to mention the problem if the
drain lines get plugged. help.
Answer I have never seen or heard of a 4 1/2 ton unit. They come in 1/2 until 4 ton, then skip to 5. I need to confirm the size of the unit before we continue. I just need the model number off of the condensing unit (outside) and I will know what tonnage you have.
