Living in Jacksonville, Florida, the cooling system runs for most of the year. Temperatures in the triple digits and an excess of humidity make the cooling system a necessity. The equipment carries a heavy workload and accounts for the majority of the electric bill. I take genuinely wonderful care of my central air conditioner. I make sure to replace the filter every six weeks and schedule professional maintenance from a licensed professional every Spring. The professional problemshoots and cleans all of the components. They replace any broken parts, tighten wires, test the refrigerant and calibrate the thermostat. This maintenance fulfills the manufacturer’s warranty and ensures the efficiency and maximum lifespan of the unit, and last summer, I was surprised when the cooling system struggled to keep the home cool. There was a significant amount of dust circulating and an unpleasant musty odor, however certain rooms felt hot and sticky. I noticed that the cooling system was running just about 24/7 and my energy bills were sky-high. When I busy cooling system repair, the professional tested the component and then worked on the air duct. She found small holes and leaks at the seams of the duct system and estimated that approximately thirty percent of the conditioner air was escaping. Fortunately, the Heating in addition to Air Conditioning business includes duct sealing capabilities. They completed the repair rapidly and effectively! Once the air duct was operating at max capacity, the cooling system was restored to peak performance. From now on, I will make sure to have the duct system worked on every couple of years. I hope to minimize stress on the cooling system to extend its maintenance life and protect its value.
