Frequently Asked Questions

Most standard 1-inch filters should be changed every 1-3 months. High-efficiency filters can last 6-12 months. If you have pets, allergies, or live in a dusty area, change them more frequently. A clogged filter reduces efficiency and can damage your system.

A well-maintained central air conditioner typically lasts 15-20 years. Furnaces can last 20-25 years. Heat pumps usually last 15-20 years. Regular maintenance significantly extends equipment life. If your system is over 10 years old and requiring frequent repairs, it may be time to consider replacement.

Costs vary based on system size, equipment brand, and installation complexity. A new central AC system typically ranges from $3,000-$7,000. A furnace replacement ranges from $2,500-$5,000. A complete HVAC system (both AC and furnace) can range from $5,000-$12,000. We provide free estimates and offer financing options.

Common causes include: dirty air filter, low refrigerant, frozen evaporator coil, dirty condenser coil, or a failing compressor. Many of these are preventable with regular maintenance. Call us for a diagnostic visit — we’ll identify the problem and provide an honest quote.

SEER (Seasonal Energy Efficiency Ratio) measures AC efficiency. Higher SEER = more efficient = lower energy bills. The minimum SEER in Georgia is 15 SEER2. We recommend 16-20 SEER for the best balance of upfront cost and long-term savings in Georgia’s climate.

Consider replacement if: your system is 10+ years old, repair costs exceed 50% of replacement cost, your system uses R-22 refrigerant (no longer manufactured), or your energy bills are significantly higher than normal. We’ll give you an honest assessment to help you decide.

In Georgia’s moderate climate, heat pumps are very efficient for most of the heating season. They’re typically more cost-effective than gas furnaces when temperatures are above 35°F. Many homeowners choose a dual-fuel system (heat pump + gas furnace backup) for maximum efficiency year-round. We can help you analyze your options.

AFUE (Annual Fuel Utilization Efficiency) measures furnace efficiency. A 90% AFUE furnace converts 90 cents of every $1 of gas to heat. We recommend at least 96% AFUE for new furnace installations in Georgia. Modern high-efficiency furnaces can reach 98% AFUE.
