Prepare Your New London Home's HVAC System for Connecticut's Winter Season

By David Rodriguez

Winter in New London is shaped by the city's coastal geography. Cold winds sweeping across Long Island Sound can make temperatures feel ten to fifteen degrees colder than the thermometer reads, and nor'easters that track up the coast regularly bring heavy snow, freezing rain, and power disruptions. For homeowners in neighborhoods like Ocean Beach, Shaw's Cove, and Hodges Square, a reliable heating system is not a luxury; it is a necessity for making it through the winter safely and comfortably.

Preparing your HVAC system for winter should begin in the fall with a professional inspection and tune-up. Our technicians check every critical component of your heating system, including the heat exchanger, burner assembly, ignition system, blower motor, and all safety controls. We test for carbon monoxide leaks, which are a serious and potentially fatal hazard in homes with gas or oil furnaces. We also verify that your system is achieving its rated efficiency, because even a small drop in performance can add hundreds of dollars to your heating bills over the course of a New London winter.

Beyond the furnace itself, we recommend that New London homeowners take steps to weatherize their ductwork. Ducts that run through unheated spaces like attics and crawl spaces lose significant heat to the surrounding air, meaning your system has to produce far more heat than your home actually needs. Sealing leaky duct joints and adding insulation to exposed runs can improve your system's delivered efficiency by fifteen to twenty-five percent, which translates directly to lower energy bills.

VENTNEX's New London team offers comprehensive winter preparation packages that include furnace inspection, cleaning, tune-up, and duct assessment. We also provide emergency heating repair services throughout the winter months, because we know that breakdowns always seem to happen during the coldest nights. Let us help you prepare now so you can enjoy a warm, worry-free winter in your New London home.
