Keen Heating & Air Conditioning - Christiana's Emergency HVAC Services

Short cycling is a common issue here, often caused by an oversized unit, a dirty air filter, or a faulty flame sensor. It wastes energy and wears out your system. Our technicians will perform a thorough diagnostic to pinpoint the exact cause, whether it's a simple cleaning, a sensor replacement, or advising on a correctly sized system for your home's specific needs.

Frozen pipes are typically due to low refrigerant, blocked airflow, or extremely cold temperatures straining an older system. If your system ices up, turn it off and call us immediately to prevent further damage. We provide emergency thawing services, locate and repair refrigerant leaks, and clean condenser coils to restore proper airflow and prevent future freezing.

We recommend our bi-annual maintenance plan, tailored for our local climate. In the fall, we focus on your heating system, checking components that lead to short cycling. In the spring, we service your AC to ensure proper refrigerant levels and airflow to prevent freezing coils. This proactive care improves efficiency, prevents breakdowns, and extends the life of your HVAC system.
