Frequently Asked Questions
My AC in Napa keeps turning on and off rapidly (short cycling). What causes this, and how can Denny's help?
Short cycling is a common issue in our Napa climate, often caused by an oversized unit, a dirty air filter, or refrigerant problems. It stresses the system and increases energy bills. Our technicians perform a comprehensive diagnostic to pinpoint the exact cause. With our full sheet metal shop capabilities, we can also assess and correct any ductwork issues contributing to the problem, ensuring your system runs efficiently for the local conditions.
What is your approach to HVAC system repair?
Our first step is always a thorough diagnostic. With over 40 years of combined experience, we believe in fixing the root cause, not just the symptom. We'll clearly explain what we find and provide your repair options. Our goal is to restore your system's reliability and efficiency, and we only recommend a replacement if it's truly the most practical and cost-effective solution for you.
Why is it important that you have both HVAC and sheet metal licenses?
Holding both the C-20 (HVAC) and C-43 (Sheet Metal) licenses means we can handle your entire system from the thermostat to the ductwork under one roof. Many performance issues stem from poorly designed or leaky ducts. Our in-house sheet metal shop allows us to fabricate custom fittings and repair ductwork on-site, ensuring your heating and cooling is delivered efficiently throughout your Napa home.
