Humidity decides how a home feels and how long it lasts. Air that is too dry cracks woodwork, irritates skin, and aggravates allergies; air that is too wet feeds mold, dust mites, and rot. The comfortable range between the two is narrow, and staying inside it takes a hygrometer, a plan for each season, and […]
Air trapped inside a radiator keeps hot water from circulating through the fins, and the result is a unit that stays cool at the top while the base warms up. The trapped air also lowers the total heat output of the system, which pushes the boiler to run longer for less warmth. Bleeding the radiators
Bathrooms generate more moisture per square foot than any other room in a house. A single hot shower releases roughly half a gallon of water vapor into the air, and when that vapor has nowhere to go it condenses on mirrors, soaks into grout, and feeds mold behind baseboards. The exhaust fan is the first
Bathroom exhaust fans are required by the National Electrical Code (NEC) and local building codes for any bathroom that lacks an openable window, and some jurisdictions require them even when windows are present. The fan has one job: pull humid air out before it condenses on walls, ceilings, and grout lines. An undersized fan fails
Your home’s air ducts work hard to heat and cool the house through the year, but they collect more than air. Dirt, dust, pollen, bacteria, pet hair, mold spores, and even spider webs or pests build up inside the ductwork, and cleaning rids the system of that solid matter and returns it to like-new condition.
When an air conditioner starts making odd sounds or cycles on and off at strange times, the temptation is to ignore it. Repairs are expensive, replacements are more expensive, and a unit that still blows cold air most of the time does not feel urgent. Small issues become major ones, though, and the longer a
When the compressor on an air conditioner stops working, the system can no longer cool the air, and every warm day after that makes the repair more urgent. On average, an AC compressor replacement costs about $800 to $2,300, with most homeowners paying around $1,200 for parts and labor. The price swings with the size
Indoor air quality is a building performance issue as much as a health issue. People in developed countries spend roughly 90 percent of their time indoors, and the air in those spaces is often more polluted than the air outside. The sources are familiar: cooking, cleaning products, building materials, furnishings, and the occupants themselves. The
Gas fireplaces deliver warmth without splitting wood, hauling logs, or cleaning ashes, which keeps them among the most popular heating upgrades in modern homes. Some units ignite with the flip of a wall switch or a tap on a remote; others are lit by turning a wall key or hex key while holding a flame
Central air conditioners move heat with two fans: the indoor blower inside the air handler and the outdoor condenser fan. The indoor fan draws warm room air across the evaporator coils, and the outdoor fan pushes heat away from the condenser as the refrigerant releases it. When either fan stops spinning, cooling output drops, the
