About 10 years ago I was talked into adding baffles to control the air flow to parts of the house because the a/c unit was too small for the space. It was reasonably effective until 4 years ago when the a/c unit was replaced. For 4 years the air in the house has been stuffy and never felt like air conditioned air. The more the unit ran, the damper the house became, so I was also running a dehumidifier and floor fans constantly. I complained for 4 years to the installing company and was repeatedly told this was as good as it would get unless I replaced the unit again, knocking out part of a wall to accommodate a larger air handler. After checking reviews on Angie's List I called Bruce Kelly in February; I explained the issues and asked if he would be willing to look at the problem. On the first visit an employee named Tommy determined that the a/c unit was not designed to be compatible with the zoning and agreed that it was actually adding humidity to the air instead of removing it. He said that the unit was running so inefficiently that it was diminishing the air quality. At his suggestion I lowered the temperature on all three thermostats, forcing air throughout the house most of the time; this was the opposite of what I had been advised by the installing company. Within 24 hours the house was drier and more comfortable and I was able to discontinue sinus medication. Mr. Kelly and crew returned a couple of weeks later for additional testing of the unit and to formalize a plan for what needed to be done. I accepted the estimate and the work was completed on March 17. As of now the unit is apparently running more efficiently; the more the unit runs, the drier the air is; and I continue to not take sinus pills. I am using the dehumidifier only on cooler, cloudy days when the a/c unit is running less, again the exact opposite of the way it has been for years. I am not totally convinced that we are done yet; things may need to be adjusted a bit as we get into the Florida summer, especially increasing the air flow into a guest room. However we have now had several days of intense sun and temperatures in the upper 80's and the house remains more comfortable that it has been for years. Throughout this process Mr. Kelly and the crew were responsive, helpful, efficient and knowledgeable. They took the time to listen to my concerns and to formulate a plan that has significantly improved the air quality in the house.
