Forgetting the Furnace Filter
One of the fastest ways to create problems with a forced-air heating and cooling system is to forget to replace the filter. Locate the furnace filter and buy replacements if the previous owners didn’t leave you a stash. Replace the filter (and get in the habit of doing it every month). Here’s how!
Failing to Clean Air Conditioner Condensers and Evaporators
A little sweat equity now will help both your wallet and your comfort level later when summer’s heat sets in. Most of the job can be done without the help of a professional, and by servicing and testing out your cooling system now, you will have plenty of time to make an appointment with an air conditioning contractor if there’s any unforeseen issues. After cutting off the electricity to the unit, vacuum the outdoor condenser’s exterior fins with a soft-bristled brush, and clear away bushes, weeds and overgrown grass within two feet of the unit. Indoors, replace the furnace filter on the evaporator unit, vacuum the blower compartment, and clean the condensation drain.
Not Mapping Out Your Home’s Main Water Shutoff Valve
Know where you main water shutoff valve is in case you need to shut off the water to your entire house.
Almost all homes have one main shutoff valve directly before the water meter and another directly after. Where the meter is located depends on the climate in your area. In cold climates, the meter and main shutoff valves are located inside, usually in a basement or other warm area to prevent freezing. In milder climates, the meter and its two shutoff valves may be attached to an exterior wall or nestled in an underground box with a removable lid.
Between the water main in the street and the meter, there’s also usually a buried curb stop valve (accessible only by city workers wielding special long-handled wrenches) and a corporation stop, where your house water line hooks up to the water main. Your city absolutely doesn’t want you messing around with these valves. Turn your water off or on using the main valve on the house side of the meter. This valve will normally be a gate-type valve, with a round knurled handle, requiring several full clockwise rotations to turn off. In newer homes, it could be a ball valve.
