Common Questions
How can a new HVAC installation help with Baltimore's high humidity?
Modern, properly sized HVAC systems are much better at managing humidity than older units. For Baltimore homes, we calculate the exact cooling capacity needed to efficiently remove moisture from the air during installation. This not only makes your home feel cooler at a higher thermostat setting but also reduces strain on the system, lowers energy bills, and prevents mold and mildew growth common in our humid climate.
My air handler fan stopped working. Is this a common repair in Baltimore?
Yes, air handler fan failures are a frequent issue we see, often due to our system's year-round workload and typical wear on motors and capacitors. DFA Mechanical's repair service quickly diagnoses the problem—whether it's a faulty capacitor, a worn-out motor, or an electrical issue. We use quality parts and get your system running again to restore airflow and prevent further damage from overheating.
What does HVAC maintenance include to prevent sudden breakdowns?
Our comprehensive maintenance service is key to preventing the failures Baltimore homeowners often face. We thoroughly clean and inspect critical components like the air handler fan motor and blower, check electrical connections, clean coils to maintain efficiency, and ensure proper drainage to combat humidity. This proactive check-up catches small issues before they lead to a complete system failure during a heatwave or cold snap.
