Question Answers

Why is my outdoor AC unit in Rochester freezing up, and how can you fix it?

Ice buildup on your outdoor unit is a common issue in our climate, often caused by low refrigerant, a dirty air filter, or a failing blower motor. It's a serious problem that reduces efficiency and can damage the compressor. At Tremblay & Son, we perform a thorough diagnostic to pinpoint the exact cause—whether it's a simple maintenance need or a more complex repair—and get your system running safely and efficiently again to handle our New Hampshire summers.

My furnace is over 15 years old. Should I consider a replacement, or can repair keep it going?

For aging HVAC equipment common in Rochester homes, repair is often a short-term solution. While we can absolutely fix many issues, older systems become less efficient, more prone to breakdowns, and costlier to operate. We provide honest assessments, comparing the cost of continued repairs against the long-term savings and reliability of a new, high-efficiency installation. Our goal is to help you make the most cost-effective and comfortable decision for your home.

What does your HVAC maintenance service include to prevent common local problems?

Our preventative maintenance service is designed specifically for systems working hard in our local environment. We perform a comprehensive check, including cleaning coils to prevent ice buildup, inspecting electrical components, checking refrigerant levels, and ensuring all moving parts are lubricated. This proactive care helps catch small issues before they become major repairs, extends the life of your equipment—especially important for aging units—and keeps your system running at peak efficiency year-round.
