Common Questions
My Baltimore air conditioner isn't cooling during a heat wave. What's the most common issue?
In the humid Baltimore summers, a sudden lack of cooling is often due to a failed blower motor or a refrigerant leak. Our technicians are experienced with these common local issues. We'll diagnose the problem quickly, explain your options clearly, and can often perform same-day repairs to restore your comfort, using parts from our own shop when possible.
Why does Ozone custom-make all its ductwork instead of using pre-fabricated parts?
Every Baltimore home, from historic row houses to newer builds, has a unique layout. Poorly fitted ductwork can lead to hot/cold spots, higher energy bills, and system strain. By custom-fabricating ducts in our own shop, we ensure a precise fit for your specific installation. This attention to detail promotes better airflow, efficiency, and system longevity.
What's included in a routine HVAC maintenance visit?
Our maintenance service is designed to keep your system running reliably and catch small issues before they become major repairs. We thoroughly clean components, check refrigerant levels, inspect electrical connections, test safety controls, and lubricate moving parts. For Baltimore homeowners, this proactive care is crucial for preparing your system for our demanding summers and winters.
