Common questions
Why is my AC running but not cooling?
An AC running without cooling can result from several issues, including refrigerant leaks, a faulty compressor, or a malfunctioning fan. In Maryland's humid climate, dirty air filters or clogged evaporator coils can also significantly impede airflow and cooling performance.
What does a typical AC repair cost?
The cost of a typical AC repair in Maryland varies depending on the specific component needing service and the complexity of the repair. Minor repairs, such as replacing a capacitor or recharging refrigerant, are generally less expensive than major component failures like a compressor or condenser coil. A thorough assessment of your system in the Baltimore area will provide precise cost factors.
What is the 3 minute rule for AC?
The '3-minute rule' for AC operation advises against short-cycling the unit, meaning turning it on and off rapidly. Allowing the system to run for at least three minutes per cycle is crucial for protecting the compressor from undue stress and potential damage. This practice is important for maintaining system longevity in Maryland's variable weather.
Are there specific licensing requirements for HVAC technicians in Maryland?
Yes, Maryland requires HVAC contractors to be licensed, ensuring that technicians possess the necessary knowledge and adhere to state safety and building codes. This licensing process ensures that services performed on your furnace in the Baltimore area are conducted by qualified professionals meeting industry standards.
