Preventative Maintenance

United Services, Inc. provides preventive maintenance for many of our customer’s residential, commercial, and industrial locations. We understand the importance and money lost from unforeseen heating, cooling, refrigeration and ventilation systems being down. That is why our maintenance program strives to eliminate the nuisance of things breaking that could have been caught during routine maintenance. Our customers will see the difference in their heating and cooling system performance almost immediately, as well as long term out of pocket cost due to untimely break downs. A maintenance program can keep your system running efficiently, which is very important as your HVAC system accounts for up to 48% of your energy usage. Keeping it as efficient as possible will put money back in your pocket.
