Common Questions
What should I do if I notice ice building up on my outdoor HVAC unit in Williston?
Ice buildup on your outdoor unit is a common issue in our climate and often indicates problems like low refrigerant or airflow restrictions. Turn off the system to prevent damage and contact Mountain Air Systems for a repair. Our technicians will diagnose the cause—such as a refrigerant leak or dirty filters—and fix it to restore efficiency and prevent further issues.
How can I tell if my HVAC system in Williston has a refrigerant leak?
Signs of a refrigerant leak include reduced cooling, hissing noises, ice on coils, or higher energy bills. Since leaks are common here and can harm your system, it's best to have a professional check it. Mountain Air Systems offers repair services to locate and seal leaks, recharge refrigerant, and ensure your HVAC runs safely and effectively.
When is it time to replace my HVAC system instead of repairing it in Williston?
Consider replacement if your system is over 10-15 years old, requires frequent repairs, or has major issues like persistent refrigerant leaks. In Williston's climate, an inefficient system can lead to high costs and discomfort. Mountain Air Systems provides installation and replacement services, helping you choose an energy-efficient unit suited to local conditions for long-term reliability.
