HVAC Service FAQs

A: The size of the HVAC system needed for your home depends on various factors such as the square footage, insulation, number of windows, and local climate. Our expert estimators at CSM will perform a load calculation to determine the appropriate size heating and cooling system for your home and make sure it is neither too large nor too small, both of which can lead to inefficiency and increased costs.

A: The cost of a new HVAC system can vary widely based on the type and size of the unit, installation complexity, and additional work needed, such as duct modifications or electrical upgrades. At CSM, we can walk you through the various financing options, manufacturer rebates, and federal or state tax credits that are available to help offset costs.

A: Energy efficiency for HVAC systems is measured by SEER (Seasonal Energy Efficiency Ratio) for air conditioners and AFUE (Annual Fuel Utilization Efficiency) for furnaces. Higher SEER and AFUE ratings indicate better efficiency. Modern systems range from 14 SEER to 25 SEER and 80% AFUE to 98% AFUE. Choosing a high-efficiency system can significantly reduce energy bills, often saving up to 20-30% compared to older units.

A: Regular maintenance is crucial for the longevity and efficiency of your HVAC system. Basic maintenance includes changing air filters every 1-3 months, ensuring the outdoor unit is free of debris, and scheduling professional inspections twice a year—typically in the spring and fall. A professional maintenance checkup from CSM will include checking refrigerant levels, cleaning coils, inspecting electrical components, and verifying overall system performance.

A: The installation process generally takes 1 to 3 days, depending on the complexity of the job and the need for additional work such as duct modifications. The process includes removing the old system, preparing the installation site, setting up the new system, connecting it to the existing ductwork and electrical system, and testing the new unit to ensure it operates correctly. CSM’s expert professional installers are trained and certified to handle these tasks efficiently and with minimal disruption to your daily routine.
