Heating and Air Conditioning questions, answered by experts

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

No, a licensed local AC repair technician must replace AC coils due to the need to handle hazardous refrigerants. Attempting DIY poses risks to your personal safety, as most refrigerants are flammable and toxic. You also risk voiding your warranty with the HVAC company and causing damage to the unit.

Freon circulates through your AC unit in a closed loop, so ideally, all of it should remain inside your system and never need to be replaced. However, if your AC starts leaking Freon (which is common), you’ll need to top it up. Known as an AC recharge, the cost of adding refrigerant to your air conditioner depends on the size and type of the AC unit, as well as the type of refrigerant.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

An HVAC unit, like a furnace, air conditioner, or heat pump, produces warm or hot air. The air ducts serve as the passages to help heat or cool air from the HVAC unit flow through the home. Air ducts are just one part of the overall HVAC system.
