Owning a cat or dog has many wonderful benefits, but a pet can also affect your heating and cooling system. Their curiosity and fondness for treating household objects as toys can damage your equipment or put your pal’s safety at risk. However, with a few precautions, you can avoid any unnecessary HVAC repairs and continue to enjoy your pet’s loving companionship. 

How to Minimize Pet-Related HVAC Repairs

1. Change the Air Filter More Often

Your HVAC's filter plays an important role in promoting indoor air quality and preventing harmful particle buildup. However, in a household with one or more pets, the air filter will accumulate debris much quicker. Try to change it every four weeks to maintain proper airflow. Regular pet grooming and vacuuming could help you to extend this time. However, during the summer, when pets shed more frequently, perform weekly inspections to determine if it should be replaced sooner.

2. Train Dogs to Urinate in a Specific Area

You can also use a potty cue like a brick or provide a fenced-in area. 

3. Install an HVAC Fence

If your pets are given free rein of the yard, then building a fence around your outdoor HVAC components is the best way to protect them. The fence should be installed at least three feet away from the system to ensure air flow into the home is not affected. Also, provide a gap between the panels so air can easily flow through it and prevent overheating.
