Refrigerant leak requires repair

When I bought a dwelling in Chicago, the heater was nearly brand up-to-date however the air conditioner was outdated! According to the dwelling inspection, the AC device could be expected to last several more years, however since the dwelling required quite a few expensive updates, I was hoping to avoid replacing the cooling system, however i made sure to be conservative with the control device setting, change the air filter properly and schedule professional maintenance in the Spring; The first Summer in our up-to-date home, the air conditioner seemed to operate just fine, however even if the device made quite a bit of noise and seemed to run non stop, the dwelling was nice and cool.

In the middle of June, there was suddenly nothing however sizzling air flowing from the vents.

I checked the batteries in the control device and tried the reset button on the cooling device however nothing fixed the problem. I had no choice however to call a licensed contractor for AC repair. The heat and humidity in Chicago can be extreme. The dwelling quickly became boiling, sticky and horribly uncomfortable. I was entirely thankful when the professional showed up to check out the system, however he took care of the operation and figured out that there was a entirely small refrigerant leak. There was no way to know if it was a up-to-date or an old leak. He proposed recharging the refrigerant and hoping for the best. The maintenance could last for a month or several years. The cost of the maintenance was two hundred dollars, which was far less than replacing the whole cooling system. The maintenance solved the problem for one year. The following June, there was once again nothing however sizzling air flowing from the vents. I was unwilling to invest another two hundred dollars into an old and failing unit. I called the same Heating and Air Conditioning contractor back. This time, I decided to invest into a up-to-date cooling system.
