A: HVAC professionals recommend a tune-up twice a year — once in spring before cooling season and once in fall before heating season. In Louisville's climate, regular maintenance extends system life, improves efficiency, and prevents mid-season breakdowns. Most service agreements include filter replacement, coil cleaning, refrigerant checks, and thermostat calibration. Q: What air filter should I use, and how often should I change it? A: Most residential HVAC systems work best with a MERV 8–11 rated filter, which balances air quality with adequate airflow. Filters should typically be replaced every 1–3 months depending on pets, allergies, and how often the system runs. In {city}, high-use summer and winter months may require more frequent changes to keep the system running efficiently. Q: When is it better to repair vs. replace my AC unit? A: A useful rule of thumb is the '5,000 rule' — multiply the repair cost by the unit's age. If the result exceeds $5,000, replacement is usually the smarter investment. Units older than 10–15 years, those requiring refrigerant recharges, or systems with recurring compressor issues are strong candidates for replacement. An HVAC technician can provide an honest assessment.
