Look for licensed, insured companies whose techs are certified for refrigerant handling, and who size replacement equipment with a load calculation (Manual J) instead of matching the old unit's sticker. Ask how diagnostic fees credit toward repairs and what their maintenance plans actually include.
Weigh age against repair cost: systems near 12–15 years with a major component failure (compressor, heat exchanger) usually justify replacement; younger systems usually justify repair. Get the repair quote itemized so you can make that call with real numbers, and be wary of same-visit replacement pressure.
A real tune-up (coil cleaning, refrigerant and combustion checks, electrical inspection) once or twice a year extends equipment life and keeps warranties valid. Plans pay off if they include those visits plus priority scheduling — read what's actually delivered, not the discount marketing.
Common causes: duct leaks or poor duct sizing, insulation gaps, or a system fighting a layout it wasn't designed for. Good companies diagnose with measurements (airflow, temperature splits) rather than defaulting to a bigger unit — bigger is often worse.
