How to DIY it: Turn it off by opening the disconnect box (typically located on the outside wall near the unit) and pulling out the disconnect block inside (above). Now take a good look at the unit. If the vents are caked with fuzz from dandelions or cottonwood trees, vacuum the vents. Then rinse the unit with a hose using moderate pressure (the flimsy fins might bend under strong pressure). As you spray, peer down into the unit. You should see water streaming through. If not, the fins are still clogged, so keep rinsing.
It is instinctual for homeowners to contact an HVAC tech when they notice irregularities in their cooling or heating system. These irregularities could be a direct result of a dirty or clogged air filter. We encourage homeowners to check their filters and replace if necessary. It’s also beneficial for homeowners with pets, carpet, or for homes near fields or construction zones to have multiple filters for convenient replacement.
If you can see light creeping beneath exterior doors, air is also escaping.

Weatherstripping already installed but you’re still suffering from a high gas bill? It might be time to replace the strips installed by the previous owners. Check out this handy tutorial on installing weatherstripping.
Ms. Artale in Westchester has a plan to fix the problem. Neither she nor her husband, Andy, 41, a program analyst, may ever learn how to repair a fence. But that won’t be the case with their 9-year-old son, Matteo. “When my son gets a little older, I’m going to apprentice him out to someone — for real,” she said. “It’s ridiculous that my husband and I don’t know how to do anything.”
The term handyman increasingly describes a paid worker, but it also includes non-paid homeowners or do-it-yourselfers. Tasks range from minor to major, from unskilled to highly skilled, and include painting, drywall repair, remodeling, minor plumbing work, minor electrical work, household carpentry, sheetrock, crown moulding, and furniture assembly (see more complete list below.) The term handyman is occasionally applied as an adjective to describe politicians or business leaders who make substantial organizational changes, such as overhauling a business structure or administrative division.[6][7]
So a door knob slammed through the wall after one too many times slamming the door. No need to call your handy contractor.

Check out this handy tutorial for more on repairing holes.
How to DIY it: This job can be messy, so protect nearby surfaces by covering them with plastic or cardboard. Spray the springs with garage door lubricant (about 
$7 at home centers). Don’t use oil, grease, or other lubricants. They may be cheaper, or you may have them on hand already, but they won’t work as well and tend to pick up dust and grit—just what you don’t want on moving parts.
