When I moved into our condo the first thing I wanted to buy was a cooling system. I knew the beach house came with outdated window a/cs in every room of the house. I was a little disgusted the previous homeowner was okay with it. Why would he want ugly window units thrown throughout the house? When I got a Heating plus A/C contractor into our beach house I realized why. My condo doesn’t have any existing Heating plus A/C ducts. Adding HVAC duct is quite invasive plus difficult on a beach house too. My older condo would literally fall to pieces if I tried to have a Heating plus A/C contractor tunnel in. My Heating plus A/C professional said I could do window A/C love the previous homeowner, ductless mini splits or high velocity AC. I had never heard of high velocity cooling before. Apparently this is a plan with HVAC duct that is half the size. It is also flexible plus can bend into the slats of a condo without causing destruction. The plan works way more efficiently too. It can suddenly whip the chilly air room to room plus lower the temperature in hours rather than love an hour. The cost on the plan is the only pitfall. You pay a pretty penny to get the plan plus do the concern cooling replacement. I was willing to pay more to have good cooling plus not have it be an eyupore though. Now that I own a cooling plan that is so powerful, I will never go back to other models. I am glad that I couldn’t get basic central AC.
