Questions
How do I determine the right HVAC system size?
Calculate your space's square footage and consult professionals for load calculations, especially for ceilings over 8 feet or unique cooling needs.
What efficiency ratings should I look for?
Check AFUE ratings (90+ for furnaces), SEER (13+ for ACs), and Energy Star certifications to ensure energy-efficient, environmentally friendly appliances.
Should I replace indoor and outdoor units together?
Replacing both units simultaneously ensures maximum efficiency and compatibility, though existing indoor units may still function with new outdoor units.
How often should HVAC maintenance occur?
Schedule professional tune-ups annually to clean components, check refrigerant levels, and calibrate systems for optimal performance and longevity.
Can older HVAC systems use Freon replacements?
Units made before 2010 can use Freon replacements, while newer systems require modern refrigerants due to environmental regulations and phase-out programs.
What are signs of poor indoor air quality?
Increased respiratory issues, persistent odors, or visible mold growth indicate potential air quality problems requiring purification or ventilation solutions.
