Replacing a furnace costs $2,800-$6,500 for most homes. The price depends on efficiency rating, size, and whether you need ductwork modifications. A 96% AFUE condensing furnace saves $250-$400 annually compared to an 80% model, paying for the upgrade in 5-8 years. Federal regulations in 2028 will require 95% minimum efficiency, making high-efficiency models the smart choice today. When to Replace ...
Why Is My Electric Furnace Blowing Cold Air? A Quick Overview If your electric furnace is blowing cold air, comfort drops quickly and the unit may run longer without actually heating, driving up energy bills and wear on components. In our field experience, quick, orderly checks usually pinpoint the cause while keeping you safe. Persistent cold air operation can strain heating elements, high limit ...
If Your Furnace Is Loud, Don't Ignore It: A Quick Safety-First Overview After decades working on home heating equipment, we treat new or loud furnace noises as diagnostic signals, not background chatter. A sudden bang, rattle, whistle, or squeal can point to airflow restrictions, worn or loose parts, ignition problems, or combustion issues. Left unchecked, these problems reduce comfort, raise ener ...
Why Furnace Safety Matters: What Every Homeowner Should Know Choosing a gas furnace is not just about heat output or efficiency. It is about keeping your home safe, comfortable, and cost efficient. In our view, a furnace is a controlled fire in a box, and the system must manage fuel, flame, heat, and exhaust safely in a confined space. Modern furnaces include multiple, built in safeguards that det ...
Why Heat Exchange Is the Core of Modern Gas Furnace Performance After decades installing and troubleshooting systems, we treat a modern gas furnace as a controlled heat exchange machine. Fuel burns inside a sealed combustion chamber, hot flue gases move through a metal heat exchanger, and your indoor air passes over the outside of those metal walls to pick up heat. The two air streams never mix, s ...
Sustainable HVAC: Modern Gas Furnaces and Tax Savings, what this guide covers Modern sustainable HVAC planning centers on pairing high efficiency gas furnaces (condensing, 95 to 98 percent AFUE) with efficient cooling, then coordinating design and installation to capture available tax credits and rebates. This guide frames sustainable HVAC around that combination, so you can understand how equipme ...
Tips for Buying a New Furnace for Your Historic Home Upgrading the furnace in a historic home is not just a swap. It is a balance of modern comfort and efficiency with preservation of original fabric, from plaster walls and trim to grilles and chimneys. Over decades working in prewar and mid century houses, we have learned that the right approach feels like tailoring a suit to a vintage pattern, p ...
Why Gas Furnace Pressure Matters for Safety, Heat and Efficiency Getting gas pressure right while a furnace is running is critical for safety, comfort, and efficiency. Live readings confirm the flame is stable, combustion is clean, and components are not stressed. We focus on what the burners see under actual load, not just at rest, because pressure can drop once the inducer and gas valve open. Te ...
When Should You Start Thinking About Purchasing a New Furnace? Think about a new furnace before it fails, the way you replace tires before a blowout. Most units deliver 15 to 20 years of service. As yours nears that window, watch for rising energy bills, uneven rooms, repeated repairs, or safety issues. We recommend planning 6 to 12 months before heating season and roughly 1 to 2 years before expe ...
