Vinegar, Not Bleach: Maintaining Your AC System
Proper HVAC maintenance goes beyond simple repairs. One common question homeowners ask is, “Is it bleach or vinegar to clean the primary drain line?” Using bleach can actually dry out the inside of your pipes, causing damage over time. Vinegar is the better choice, creating a protective film inside the line while keeping it clean. Our technicians guide you on proper maintenance techniques so your system stays efficient and safe.
Helping Homeowners Stay Informed and Comfortable
Our goal isn’t just to repair HVAC systems—it’s to educate homeowners. From understanding thermostat settings to managing indoor humidity, we walk you through the “why” behind our work. We teach you how to spot warning signs, maintain airflow, and prevent drain clogs. Whether it’s choosing between AC repair or replacement or learning how to balance humidity in older homes, we empower you to take charge of your comfort.
Common Questions From Local Homeowners
How Often Should My HVAC Be Serviced?
We recommend a complete system inspection and tune-up twice a year—ideally before the cooling or heating season begins.
What’s the Right Time to Replace My System?
If your AC or furnace is more than 10–15 years old, struggles to maintain temperature, or needs frequent repairs, replacement could save money long-term.
How Can I Reduce My Energy Bills?
Regular maintenance, sealing duct leaks, upgrading insulation, and installing a smart thermostat can dramatically cut energy costs.
Is Vinegar Really Better Than Bleach for My AC Drain Line?
Yes—vinegar keeps lines clean while protecting pipe integrity, unlike bleach, which can dry and crack PVC.
