Herrick Manufacturing - Lawrenceville's Top-Rated HVAC Repair

Short cycling, where your system turns on and off too frequently, is common here and often caused by an oversized unit, a dirty air filter, or refrigerant issues. It wastes energy and strains components. Our technicians perform a thorough diagnostic to pinpoint the exact cause—whether it's a simple filter change, re-calibrating the thermostat, or addressing a refrigerant leak—and provide a lasting repair to restore efficiency and comfort to your home.

Absolutely. A malfunctioning or miscalibrated thermostat is a frequent culprit for cooling problems in our area. It may misread your home's temperature, causing the system to run non-stop or not engage at all. We test your thermostat's accuracy, check its wiring, and can provide expert recalibration or recommend a reliable upgrade to a programmable or smart model, ensuring it accurately manages your system for optimal comfort and efficiency.

The single most important task is changing your air filter regularly, typically every 1-3 months. A clogged filter is a leading cause of short cycling, reduced airflow, and system strain in our climate. It forces your HVAC to work harder, increasing energy costs and the risk of breakdowns. We always check this during a service visit and can help you set a reminder. Consistent filter changes are a simple, cost-effective way to maintain system health.
