Signs of a refrigerant leak include higher utility bills, increased humidity in the house, weakened AC performance, and a hissing sound from the system.</div>

Heating and Air Conditioning questions, answered by experts

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

Good news: Your AC system doesn’t need Freon (a popular refrigerant) added regularly, if ever. Freon only needs to be added when there’s a refrigerant leak; however, it’s not uncommon for a gradual leak to occur every 5 to 15 years. Signs of a refrigerant leak include higher utility bills, increased humidity in the house, weakened AC performance, and a hissing sound from the system.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

HVAC technicians charge around $175 per hour, but anywhere between $100 and $250 per hour isn’t uncommon. The total cost of your HVAC service depends on the type of work, the type of system, and more. Here are some important cost factors to consider to get accurate pricing:

Time of year
Urgency of your repair or service
Type of system
Type of repair you need
Whether or not you have a service contract
Size of your HVAC system
Brand of HVAC equipment

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.
