Cleaning the vents

This time but, I was meant with a strong, steady flow of cool air, blasting out of my cooling system vents

Lately, everytime I went to use my a/c equipment I had actually little air coming out of the vents, but i even stood in front with my hand held out in front of the vents plus sure enough there was almost no air coming out. I decided to call my uncle, then my uncle is the owner of a heating plus a/c business plus I’m sure she could send someone out to service it, then sure enough when the HVAC specialist arrived she took a close look at my heating plus cooling method plus told me that my air ducts were badly in need of a cleaning, they were heavily plugged plus that is why almost no air is coming out… She also recommended me to have my air duct resealed plus cleaned. I agreed plus she got straight to work… The HVAC serviceman was nice, but the price was costly. I hadn’t bothered to check prices before hand plus just had him make the necessary adjustments plus now that it was fixed I had to pay for it. She gave me the total plus I reluctantly paid the price before heading back inside my house, now approaching the temperature control, I turned on my cooling system as I usually do plus held my hand out in front of the vents. This time but, I was meant with a strong, steady flow of cool air, blasting out of my cooling system vents. Turning the a/c down slightly I went plus sat down in my chair to relax. It may have been extravagant, but having the cooling system fixed was worth it.
