Questions
How often should I change HVAC filters?
Filter replacement frequency depends on factors like system type, building occupancy, and environmental conditions. High-traffic areas typically require quarterly changes, while low-use facilities may extend intervals.
How long should refrigerant last?
Refrigerant should last equipment lifetime under normal operation. Leaks, improper installation, or theft may require recharging. Professional inspection confirms system integrity.
When was R-22 phased out?
Production of R-22 refrigerant ended January 1, 2020. Legacy helps clients transition to EPA-approved alternatives through system retrofits or replacements.
What temperature settings save energy?
Georgia Power recommends 68°F heating and 78°F cooling for optimal efficiency. Each degree adjustment reduces energy usage by 3-4% annually.
How long do HVAC systems last?
Properly maintained systems last 15-20 years. Regular maintenance extends lifespan while ensuring optimal performance and energy efficiency.
What are benefits of maintenance agreements?
Planned maintenance improves system efficiency (10-40% energy savings), prevents costly breakdowns, extends equipment life, and ensures priority emergency service with discounted labor rates.
