Heating and Air Conditioning questions, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

If you run an AC with a dirty filter, it could allow dust and dirt to build up in your ductwork, which could make you sick. At the same time, your air conditioner won’t work as efficiently as it would with a clean filter, likely resulting in less airflow, more wear and tear on your HVAC system, and higher energy bills.

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.
