Frequently Asked Questions

Q1: How often should I have my HVAC system serviced?

It is recommended to have your heating system serviced in the fall and your cooling system serviced in the spring. Biannual maintenance is crucial for efficiency, safety (especially for furnaces), and preventing mid-season breakdowns.

Q2: What are the signs I need to replace my HVAC system rather than repair it.

Consider replacement if your system is over 10-15 years old, requires frequent repairs, causes rising energy bills, struggles to maintain temperature, or uses R-22 refrigerant (which is phased out and very expensive).

Q3: What is the benefit of a "smart" thermostat?

Smart thermostats (like Nest or Ecobee) learn your schedule, allow remote control via smartphone, provide energy usage reports, and can auto-adjust for savings. Many local HVAC companies can properly install and integrate them with your system for optimal performance.
