Is your dog getting too close to your AC unit?
The damage adds up fast and the risk to your dog is real. Answer a few quick questions to get a personalized recommendation for your property.
Your AC unit and your dog are a bad combination.
Dog urine is highly acidic. Regular exposure corrodes the copper coils inside your condenser, causing refrigerant leaks and system failure. Coil replacement alone can cost up to $2,500, and most HVAC warranties do not cover pet damage.
But the risk is not just to your equipment. Condenser fins are sharp. Exposed wiring is dangerous. A dog that gets too close, chews a wire, or cuts themselves on bent metal fins can end up in a veterinary emergency.
Outdoor Shields® Plus by Invisible Fence® Brand creates an adjustable circular boundary around your AC unit that your dog learns to stay away from completely. It is weatherproof, discreet, and pairs with your existing Invisible Fence® Brand system if you have one.

Three Reasons to Keep Your Dog Away From the AC Unit
Urine Destroys the Coils
Dog urine is acidic enough to corrode the copper coils inside your condenser over time. Once the coils fail, refrigerant leaks and the system stops cooling. Coil replacement can cost up to $2,500, and most HVAC warranties exclude pet damage entirely.
Physical Damage Compounds the Cost
Dogs that chew electrical wiring, scratch condenser fins, or knock into the unit cause damage that goes beyond corrosion. Bent fins reduce airflow and efficiency. Damaged wiring is a fire and system risk. Each incident adds to a repair bill that grows quietly over time.
The Unit Is a Hazard to Your Dog Too
Condenser fins are thin, sharp metal. Bent or broken fins can cut a dog that gets too close. Exposed or chewed wiring is an electrocution risk. Keeping your dog away from the unit protects both your investment and your pet.
We had already spent over $1,200 on coil cleaning before our HVAC tech told us dog urine was the cause and warned us we were looking at up to $2,500 to replace them. We installed Outdoor Shields® Plus the following week. Our dog has not gone near the unit since and our last inspection came back clean.
