David Martin Heating & Cooling - Frankfort's Reliable HVAC Repair

Short cycling is a common issue here, often caused by an oversized unit, a dirty air filter restricting airflow, or a faulty thermostat. This constant stopping and starting wastes energy and wears out components. Our technicians will diagnose the root cause—whether it's a simple filter change or a more complex refrigerant or electrical issue—to restore normal, efficient operation for your home.

We recommend checking your filter monthly and changing it at least every 1-3 months, depending on factors like pets, allergies, and local construction dust. A clogged filter is a leading cause of poor airflow, which strains your system, reduces efficiency, and can even lead to frozen coils or overheating. Regular filter changes are the easiest way to maintain system health and improve your indoor air quality.

While maintenance is key for prevention, signs you need a repair include strange noises (grinding, squealing), uneven heating or cooling between rooms, a sudden spike in your energy bill, or the system failing to start. If your unit is short-cycling or you notice weak airflow from vents, it's time to call us. We'll pinpoint the issue before a small problem becomes a major, costly breakdown.
