Frequently Asked Questions
How often should I service my HVAC system?
Most HVAC professionals recommend servicing your system twice a year - once before the cooling season (spring) and once before the heating season (fall). This helps ensure optimal performance and can prevent costly breakdowns.
What's the average lifespan of an HVAC system?
Most HVAC systems last between 15-20 years with proper maintenance. However, factors like usage patterns, maintenance frequency, and system quality can affect longevity. If your system is approaching 15 years old and requiring frequent repairs, replacement may be more cost-effective.
How can I improve my HVAC system's efficiency in Baltimore County?
Regular maintenance, upgrading to a programmable thermostat, sealing air leaks, improving insulation, and replacing air filters regularly can all improve efficiency. Many contractors in Baltimore County offer energy audits to identify specific improvements for your property.
