Questions
How often should HVAC filters be changed?
Disposable filters require monthly replacement, pleated filters every 90 days, and media filters annually. Schedule bi-annual maintenance for optimal system performance.
Do bigger AC units perform better?
Proper sizing is critical. Oversized units cause short cycling and humidity issues. Our technicians perform load calculations to recommend the right system capacity for your space.
How long do HVAC systems last?
Typical lifespan is 12-15 years. Regular maintenance extends system life while maintaining energy efficiency and preventing costly breakdowns.
Can I replace just the outdoor AC unit?
Modern systems require matched components using R-410A refrigerant. Replacing both indoor and outdoor units ensures efficiency and warranty validity.
How often should HVAC systems be serviced?
We recommend twice-yearly maintenance: spring AC check-ups and fall furnace inspections to ensure seasonal readiness and prevent system failures.
How can I improve indoor air quality?
Our Clean Air Package includes duct sealing, filtration system upgrades, and air purification solutions to reduce allergens and improve overall indoor air quality.
