Today, our team was contacted to enhance the air quality and climate control at an animal vet hospital in West Friendship. Understanding the critical role a conducive environment plays in the operation of a vet hospital, we came prepared. We successfully installed a new Energy Recovery Ventilator (ERV) and a package rooftop unit. Both these installations will promote better indoor air quality and temperature regulation, ensuring a comfortable and healthy atmosphere for both the animals and staff. We are thankful for the opportunity to improve daily comfort for the hospital's inhabitants, and we look forward to offering our services again when needed.
