Until recently, I didn’t even understand how air conditioners worked. Then summer came along, and as the temperatures outside got higher and higher, so did my electric bill. I couldn’t for the life of me figure out why my power bill was so high, so I started doing some research online to try and figure out what the problem was. I had a hunch that it had something to do with the refrigerant in my air conditioning unit, and it turned out that I was right! I learned that my air conditioner uses refrigerant to transfer heat and eventually remove it from my house. Well, since my A/C was suffering from low refrigerant, my unit was unable to remove the heat from my house efficiently. It was so hot in my house that I couldn’t sleep, even with my ceiling fan going on full blast. I started putting my head in the refrigerator just to get a little bit of relief! That sounds crazy, but it was that stuffy and hot in my house. It turns out that the reason my A/C had low refrigerant was because it had most likely developed a leak somewhere. And even though I had been able to diagnose the problem with my air conditioning myself, I still had to call my local HVAC company to have a professional come out to service my unit. They had to figure out exactly what had caused the leak, where the leak was occurring, and what they needed to do to repair my A/C unit.
