Which way does an HVAC filter go in?
The airflow arrow on an HVAC filter points toward the blower, away from the return duct. At a wall or ceiling return grille, the arrow points into the wall.
-
Why is my smoke detector blinking red?
On most alarms, a red light blinking every 30 to 60 seconds is normal. It means the unit has power and is working. A red blink with a chirp is what to check.
-
Why does my GFCI outlet keep tripping?
A GFCI trips when current leaks to ground, about 5 milliamps. Repeated trips usually mean moisture in the outlet, a faulty appliance, or a worn-out GFCI.
-
Why is my smoke detector chirping?
A chirping smoke detector almost always means a low battery. If a fresh battery doesn't stop the chirp, the sensor is at end of life and the unit needs replacing.
-
How often should I clean my gutters?
Most gutters need cleaning twice a year: late fall after leaves drop, and early spring. Homes with overhanging trees need three or four cleanings a year.
-
How do I winterize my outdoor faucet?
Winterize the outdoor hose bib before the first hard freeze: disconnect the hose, close the interior shutoff, then open the bib outside to drain the line.
-
What MERV rating should I use for my HVAC filter?
For most homes, MERV 8 to 11 is the right range. MERV 13 is the upper end residential blowers handle. Higher ratings stress the system and starve airflow.
-
When should I replace my smoke detectors?
Replace smoke detectors every 10 years. Check the manufacture date on the back. Replace batteries yearly unless yours has a 10-year sealed cell.
-
How often should I flush my water heater?
Most tank water heaters need a flush once a year to clear sediment. Hard-water areas need it every six months. Tankless heaters need an annual descale.
-
How often should I clean my dryer vent?
Clean your dryer vent at least once a year. Daily use shortens that to every 6 months. Failure to clean is the leading cause of dryer fires in the U.S.
-
How do I test a GFCI outlet?
Press the TEST button on the outlet: power to that receptacle and any outlets it protects should cut off immediately. Press RESET to restore. Test every GFCI once a month.
-
Where is my main water shutoff valve?
The main water shutoff is usually inside the basement or garage where the supply line enters the house. In warm climates, check an exterior wall or meter box.
-
How often should I change my HVAC filter?
Most homes need a new HVAC filter every 90 days. Pets, allergies, or year-round use shorten that to 30 to 60 days. Thicker media filters last longer.
-
How often should I test my sump pump?
Test your sump pump every 90 days, and again before any heavy rain. Pour five gallons into the basin and watch the pump kick on within seconds.
