Question Answers
What's the most common cause of furnace ignition failure in New London winters, and how do you fix it?
During our cold New London winters, a frequent culprit for furnace ignition failure is a dirty flame sensor. Over time, dust and carbon buildup can prevent the sensor from detecting a flame, causing the system to shut down as a safety measure. As part of our repair service, we carefully clean or replace the sensor, test the ignition system, and ensure your furnace operates reliably and safely through the season.
Do you offer maintenance plans to help prevent HVAC breakdowns?
Yes, we provide thorough HVAC system maintenance designed to catch small issues before they become major problems. Our maintenance service includes inspecting electrical connections, checking refrigerant levels, cleaning critical components like condenser coils, and testing system performance. Regular maintenance by our experienced mechanics is a proactive way to improve efficiency, extend your system's lifespan, and maintain your comfort year-round.
I need a new water heater installed. What does your process involve?
Our water heater installation service begins with assessing your home's needs and your current setup to recommend the right unit. We handle the entire process, from safely removing the old heater and disposing of it, to installing the new one with proper connections, valves, and pressure relief. We then test the system thoroughly for leaks and operation, ensuring you have a reliable supply of hot water and explaining any new features or maintenance tips.
