HVAC FAQs

A: You should service your HVAC system at least once a year. Ideally, schedule maintenance for the heating system in the fall and the cooling system in the spring. Regular servicing keeps your heating and cooling equipment working efficiently, prolongs the system’s lifespan, and helps prevent unexpected breakdowns.

A: Signs that your HVAC system needs repair include unusual noises like banging, clanking, or squealing, strange odors from vents or the unit, weak or inconsistent airflow, uneven heating or cooling across different areas, sudden increases in energy bills, and frequent cycling on and off. If you notice any of these signs, contact your local experts at CSM to diagnose and fix the issue.

A: You can improve your HVAC system’s energy efficiency by regularly replacing or cleaning air filters every 1-3 months, sealing duct leaks to prevent air loss, installing a programmable thermostat to optimize temperature settings, ensuring your home is properly insulated, scheduling regular maintenance to keep the system running smoothly, and keeping vents and registers clean and unobstructed.

A: Strange noises can indicate various issues. Banging or clanking may suggest loose or broken parts, squealing could be due to issues with the blower motor or belt, and hissing might indicate refrigerant leaks. Rattling is often caused by debris in the system. Each noise type typically points to a specific problem, so it’s important to have an expert like CSM inspect and address the noise promptly to prevent further damage.

Consulting with a professional such as CSM can help you choose the right HVAC system for your home and budget. We begin by assessing your home’s size and layout to determine the appropriate system capacity. We can help you understand and interpret energy efficiency ratings (SEER for cooling, AFUE for heating) to save on long-term costs, and decide on the type of system (central air, ductless, heat pump) based on your specific needs and climate. CSM only uses reputable brands like Trane and Mitsubishi, which offer ironclad warranties and reliable longevity.
