this park has pathways with rubber..and these rubber is the source of electricity of the lamp posts. when people are walking on the streets, the rubber are pressed by the force of the feet and produces electricity to light up the posts. so people must keep on walking to see the beauty of the lights. this park is somewhere in europe or americawhat's the name of this park?
The contractor is full of baloney, don't use him again. As to the HVAC using up refrigerant, don't you believe it. It's a hermetically sealed system with no openings - if it were using up refrigerant, then where would the used up refrigerant go? Wait a moment - be sure the valve caps are on your access ports, and are snugged down. They're important. A properly sealed HVAC system can go years without losing any refrigerant. Under ideal conditions, it should never lose any at all. But ideal conditions are pretty uncommon, and of course vibration, wear and accidental damage all take their toll. A better answer from the contractor would have been for him to whip out the leak detector and nail down where your refrigerant is escaping from, and then present you with the two options: 1) Refill it and commit to refilling it for the time being. In the interest of full disclosure if I were your tech, I would tell you that R-22 refrigerant (which is most likely what your system is using) is being phased out and the prices associated with it are through the roof and gaining altitude even as we speak. If you hope to just top up the system in another couple of years, the price tag is likely to knock your socks off. 2) Repair the system so there are no further leaks, and whatever money you spend on topping up this time will be a much more lasting investment. Yes, repairing the leaks will cost a tidy sum but compare that to the ongoing cost of topping up when the refrigerant's price continues to rise - and when you finally do change the system over to a new refrigerant, you'll still have a leaky system if you don't get it repaired. Pay now and have done, or pay and pay and pay.
Ive worked at stanley steamer for a few years now but dont have formal water damage training. So what I would do if I was you was to call a water extraction company or somehow get a professional opinion on how to fix the damage. Get it it writing and show your landlord. Might work
The contractor was absolutely lying! Probably too lazy to search for the leak. All air conditioning and refrigeration systems are sealed and should never use refrigerant unless there is a leak. I have worked on systems that were thirty years old that still had the original charge.
