A: Popping noises can indicate that the ducts are too small for the airflow, which may require adjustments by a qualified technician.
Q: What is a zoning system?
A: Zoning systems separate the ductwork into different segments, allowing for individual temperature control in each segment, making the air conditioning more efficient.
Q: How can I increase the efficiency and lifespan of my HVAC system?
A: Regular maintenance, such as cleaning or replacing air filters frequently, can help improve efficiency and extend the lifespan of your HVAC system.
Q: How much will HVAC service or replacement cost?
A: Costs can vary widely depending on the type of service, the cost of replacement parts or a new system, and the rates charged by the HVAC technician.
