The most common causes are a clogged air filter, an outdoor circuit breaker trip, low refrigerant from a leak, or a failed capacitor. We test the system and get cold air blowing the same day.
Should I repair my older AC unit or upgrade to a new heat pump?
If your unit is under 10 years old and the repair is simple, repairing is usually best. If it is over 12 to 15 years old and needs major parts, upgrading to a high-efficiency inverter heat pump can save up to 35% on monthly electric bills.
