I’ve had a very poor history with air conditioning. It seems like every summer I’ve got challenges with my HVAC system. I often return to my house after a day of work and I’m afraid to open the doorway. I am afraid that I may feel terrible heat from in my home. I have come to the house from work on several occasions to no air conditioning at my house. Just recently, I came home and there seemed to be no air conditioning on in my house. In fact the the air was running except it was just warm air. I certainly don’t want warm air in my home in the summer season. So I was required to call my local HVAC provider. I had no idea what was wrong with my HVAC system. It feels like every time the air conditioning does not work it’s a new problem. So I don’t even bother with the idea anymore. I wouldn’t even know how to fix it. So I leave it up to my local HVAC company to send an HVAC professional to look at my system. This most recent time it was found that the refrigerant that makes air cool was leaking out of the tank. The tank must have been completely old so all the refrigerant leaked out due to a crack that was found in it. All the HVAC professional was required to do was replace the refrigerant take inside the HVAC system. After this you refill the refrigerant reservoir. After about half-an-hour I felt the air conditioning come back on in my house. I wonder when these air conditioning difficulties will finally stop for me.
