There is likely to be a "trip" or "service call" charge as well as the cost of the coolant (plus labor) added to the total bill. Rates vary from one region to another, and from one company to another, so it's almost impossible to cite a price that you would pay. Call a local AC repair facility and inquire to the trip and labor charges and ask for an estimate.
No, you cannot recharge a window AC unit with refrigerant yourself. It requires a professional HVAC technician to safely and properly recharge the refrigerant in an AC unit.
The recommended recharge window for a window AC unit to ensure optimal performance is typically every 2-3 years.
To recharge your window air conditioner using a recharge kit, follow the instructions provided in the kit. Typically, you will need to locate the low-pressure service port on the unit, connect the recharge hose, and add refrigerant as directed. Be sure to follow safety precautions and guidelines to avoid any accidents or damage to the unit.
To recharge a window AC unit, you will need to contact a professional HVAC technician. They will be able to safely and properly add refrigerant to the unit to ensure it is working efficiently. It is important to have a professional handle this task to avoid any potential hazards or damage to the unit.
depends on freon type,quanity,hourly rate of hvac co.
depends on the size of the unit you want to use and the size of the window plus how many rooms you are trying to keep cool and if the unit is energy efficient and depends on how much you are willing to spend on the unit
Probably close to or more than a new unit would cost.
Recharging a window AC unit with refrigerant involves locating the service valve, connecting a refrigerant canister, and slowly adding refrigerant until the correct pressure is reached. It is important to follow the manufacturer's instructions and safety guidelines to prevent damage to the unit.
Unit cost is how much is costs to make. Unit price is how much you sell it for. The difference is profit.
If there is not a pressure tap on the suction line(the larger pipe comming off of the compressor) you need to install a piercing valve with a 1/4" flare for the refrigerant hose and charge. Depending on the age of the window unit it might be worth buying a new one.
You do not recharge coolant, you replace it. If you are referring to refrigerant in the A/C unit, then first you need to have the leak repaired. It would not need recharging unless it is leaking. It is illegal to add refrigerant to a system that is leaking without repairing the leak. This is a job for a professional with the proper tools and knowledge. This is not a DIY repair. The cost depends on where the leak is.
No. First off, the trustworthiness of any such kit sold at Walmart is questionable. Secondly, the kits are intended for automotive AC systems, and will come with R134a refrigerant... window units use a different type of refrigerant (often R22, from my understanding). Different refrigerants cannot be blended, and doing so will ultimately damage the AC unit.
