Standard filters should be replaced every 1-3 months. Homes with pets, allergies, or heavy dust may need monthly changes. High-efficiency filters can last up to 6 months.
A new central AC unit typically costs $3,500-$7,500 installed. Factors include system size (tonnage), SEER rating, ductwork condition, and your climate zone.
Minimum SEER2 is now 14-15 depending on your region. For the best efficiency and long-term savings, look for 16+ SEER2. Higher ratings save more on cooling costs.
Most HVAC systems last 15-20 years with proper maintenance. Annual tune-ups, regular filter changes, and prompt repairs can extend system life significantly.
Common causes include low refrigerant, a dirty air filter, a frozen evaporator coil, a faulty compressor, or thermostat issues. Start by checking the filter and thermostat settings.
Professional duct cleaning typically costs $300-$700 for an average home. Be wary of companies advertising very low prices, as they may upsell or do incomplete work.
Consider replacing if the system is over 15 years old, needs repairs costing more than 50% of replacement value, uses R-22 refrigerant, or has declining efficiency.
A mini-split is a ductless heating and cooling system. It has an outdoor compressor and one or more indoor units. Great for room additions, converted garages, or homes without ductwork.
HVAC systems should be professionally serviced twice a year — once in spring for cooling and once in fall for heating. Regular maintenance prevents breakdowns and extends system life.
AC sizing depends on square footage, insulation, climate, and other factors. A rough guide is 1 ton per 500-600 sq ft, but a professional load calculation gives the most accurate sizing.
