How to Conduct a Home Energy Audit: What to Expect A home energy audit is a structured, whole-house assessment that reveals where your home is wasting energy and how to address it most cost effectively. We think of it as a checkup that ties comfort, air quality, and utility costs together. A professional audit typically takes 2 to 4 hours and blends utility bill analysis, a room by room visual ins ...

Is It Safe to Run an AC Unit All Day? A Quick, Practical Overview When temperatures spike, many homeowners ask if running the AC all day is safe and smart.

Why Proper Insulation Matters for Year Round Home Comfort Proper insulation is a foundational element of a comfortable, efficient home. It slows the movement of heat through the building, so rooms stay near the thermostat setting in January and July. Think of it as a lid that keeps heat where it belongs. By resisting heat flow in walls, attics, floors, and ducts, insulation reduces hot and cold sp ...

Black Friday 2026 HVAC Deals: Why This Holiday Is the Moment to Upgrade HVAC can account for about 40% of a home’s energy use, so upgrades made now can deliver comfort gains and lower operating costs for years. Around Thanksgiving week, retailers, manufacturers and contractors push discounts on heat pumps, furnaces, central AC, ductless systems, smart thermostats and filters, often bundled ...

Goodman 4 Ton 13.5 SEER2 + 120,000 BTU Furnace (R 32): Overview This matched system pairs a 4 ton, 13.5 SEER2 condenser with a 120,000 BTU two-stage, variable-speed ECM gas furnace using R-32. In our field experience, it fits larger homes or colder regions that need strong heating capacity with steady, quiet airflow. Expect cooling costs about 20 to 35 percent lower than an older 10 SEER setup, pl ...

Gas Furnace or Heat Pump: what's the practical difference for your home? Choosing between the two affects comfort, monthly energy bills, indoor air quality, and equipment lifespan. A gas furnace burns natural gas or propane to produce high temperature heat inside the home. A heat pump uses electricity to move heat from outdoors to indoors, rather than creating it, and it also serves as your centra ...

How Furnace Filters Protect Your Heater This Spring Spring is the moment to catch issues that heavy winter runtime created. Your filter is the heater's first line of defense, sitting upstream to catch particles before they reach sensitive parts. After months of cold-weather cycles, many filters are at the end of their useful life, so a quick check now can prevent trouble from snowballing into a re ...

Understanding BTU: The Single Number That Shapes Your Comfort BTU, or British Thermal Unit, is the amount of energy needed to raise one pound of water by one degree Fahrenheit. It is the core unit we use to size furnaces, air conditioners, and heat pumps. Think of BTU like the sizing on a pair of shoes: get it right and everything fits, go too small or too large and every step is uncomfortable. Th ...

Why Air Conditioner Energy Use Matters for National Electricity Systems Air conditioning is a rapidly expanding driver of electricity consumption globally and already a large electrical load in the U.S. Over three decades in HVAC, we have watched cooling shift from a luxury to a system-level force. ACs keep homes livable in hot months, but the comfort we enjoy also shapes utility demand patterns, ...

Why Geothermal Heat Pumps Deliver Smarter Heating and Cooling Geothermal, or ground-source, heat pumps use the earth's relatively steady subsurface temperature to move heat into or out of a building. Think of a refrigerator, but serving the whole home and capable of heating and cooling. Because they transfer heat rather than create it by combustion, they avoid the losses that come with burning fue ...
