  • A stumper for the HVAC technicians?

    Maintenance & Repairs - 5 hours ago

    Additional Details

    So I'm in an HVAC class. My lab was a unit change out. Everything was going smooth and easy, until I tried to raise the head pressure to 278 psig. The first time I got my head pressure up around 278 psig. While measuring my subcool(which was fluttering around 20 degrees) the high pressure switch cut out. After that It cut out at around 160psig. I bypassed the hi/lo pressure switches, because they kept tripping, and raised head pressure to 200 psig. Above that and the compressor cuts out while the condenser fan keeps blowing. I weighed in the charge of 5.8 lbs of R-22, like the label on the unit called for, if anything it is overcharged. I pulled a triple evac. It is not on me yet to troubleshoot this unit, but I hate failure. This one has two of my instructors suspecting different causes; bad compressor or undercharge. Any ideas? To raise the head pressure, we wrap the coils with plastic and limit airflow. I say it is overcharged because 5.8 lbs is a complete charge with 25' of lineset. This unit has approximately 19' of lineset. The evap coil was not replaced with the condenser. The TXV works fine, it maintains 10 degrees superheat. I think I got everything. The filter drier is just a standard issue. About the size of an orange. The sight glass has a few stray bubbles, which I have received mixed information on. A short time instructor said a proper charge should show no bubbles, another instructor said a proper charge would show some bubbles. The subcool number does show an undercharge...either a coolant loss or I had the scale set to kilos? I think it was a potential relay. All those little black boxes look the same, and I could not see the wiring diagram without removing it from the unit. discharge temp. was around 85-110, the higher number with higher pressure. hermetic, scroll, 208 volt, high temp, used residential unit. We have dozens of A/C's, I swapped out a 13 SEER unit for an antique 12 SEER Rheem. I don't remember the amp draw, but it did increase as pressure rose. This problem developed near the end of the day. So we didn't have time to start troubleshooting. School is closed till Monday, but I have been pondering this since last night. From the questions you have led me with, I tend to suspect the compressor. The compressor was extremely hot to the touch. I think it was a potential relay. I could not read the schematic on it. I admit I am a rookie with no practical field experience. evap pressure stays steady at 70 psig. The pressure rises to around 80 psig when head pressure is forced up to 200 psig.

  • Drywalling question(gaps and jagged sheetrock).?

    Do It Yourself (DIY) - 11 hours ago

    Additional Details

    I'm not sure if I make sense to you, this is hard to explain. Basically there is a hole or groove about a inch deep in the sheetrock where he failed to snap the board clean. The grove is located in the middle on the ending. Now when I tape over this I can sorta see that I'm taping over a hole in a wall. I feel like this is not the proper way to do it and it can easy be "punched" through later on. What can I do to fix this gap so I can tape over something solider and the paste?

  • problems hooking up overhead fan?

    Do It Yourself (DIY) - 18 hours ago

    Additional Details

    okay, I am having problems with this stupid fan, I am sure I have the wires connected right, the green is connected to the bare, the white to the white, black to black and red to blue. But when I turn on the switch, the fan doesnt turn on. Its not the breaker, it has power.. what should I do? yes i tried the chains, but it still doesnt work. I just tried rewiring it, (ceiling first) white to white, black to blue, red to black, and bare to green, and the second switch worked with the fan, but the light still doesnt work. i have 2 switches and no idea what you mean by hots the fan has a blue, green, white, and black wire. the ceiling has white, black, bare and red. I have no idea what to hook up and what not, and I moved this from one room to another, so I dont have a manual. okay randy so to attach the fan to one switch attach them both to the black one? well i tried attaching both the blue and black from the fan to both the black and the red from the ceiling. if they are attached to the black, nothing works. If they are attached to the red, the light works, but the fan still doesnt okay i have the light turning on, but the fan isnt working, i think you are right and that there is a problem with the switch wiring. Is it difficult to fix this?

Ten yard problems and how to fix them

Make the most of your garden all year round with these tips.

By Jennifer Gruden, 50Plus.com
Ten yard problems and how to fix them

As summer gives way to fall many of us will still be spending time out in the garden, entertaining, relaxing, and enjoying the time in the sun before the winter. But real yards aren't without their issues too. Here are ten common yard problems and how to address them.

The grass is not greener

If your grass is suffering due to lack of care, it may be time to evaluate your fertilizing, watering, and mowing schedule. But another alternative is to replace it all together. Alternative ground covers can provide greenery without all the drudgery. Clover can be a remarkably easy alternative. And in shady areas moss may well be the logical choice. Other ground covers include thyme and periwinkle. Ask for advice at your local nursery.

Don't miss out on fall foliage

Although many of our Canadian trees, including the iconic maple, don't lack for fall impact, some planning can add even more colour to your garden over the fall. Try sumach (the non-poison kind of course), red chokeberry, and tor spirea. Another approach is to replace container plants with displays of dried flowers, gourds, and other fall ornaments.

Winter blahs

When planning a garden don't forget to incorporate some evergreen and other plants of winter interest. Also plan for height: if all your foliage is low lying enough to be covered by snow, it doesn't matter which colour it is. Ornamental grasses, plants which leave interesting fruit such as bayberry plants, and plants with coloured barks such as red osier dogwood are great additions to the more traditional conifer plants to keep gardens vibrant.

Grey and faded decks and fencing

As long as the wood is still sound, you can clean and revive your deck and fencing. First, inspect the area to see whether there is a stain or sealer on the wood. Although deck cleaners are made to clean stained or sealed surfaces (and will in fact remove the sealer), a stained section will make the wood look blotchy if the rest has worn away. If you can see stain left in low-traffic areas, use a stripper in the area to get rid of it, following the manufacturer's instructions.

The next day (or later) you can use the deck cleaner -- plan to spray and then do a lot of scrubbing, again, according to the manufacturer's instructions. Take care not to use a pressure washer at too high a setting or you could damage the soft wood's surface. Finish with a sealer and you'll have what looks like a new deck or fence.

Clear clutter

It may all be useful objects stacked by the garage to you, but to others those bits and pieces can look like junk. If they're not worth actual storage space, it may be time to get rid of them. Go through the pile and be ruthless about whether or not you actually have specific plans -- and a specific timeline -- to use each item. If not, donate the item or have it hauled to the dump.

Lack of privacy

The long term solution may be to plant fast-growing shrubbery, but there's also a this-year fix: try using matching stepladders as a makeshift arbor to shield your yard from the neighbour's, and train vines up as well as placing plants on the steps. Tall container plants can also help to create a green fence of sorts.

Swimming pool ate garden

If your backyard seems to be all pool, take heart. There is a solution: free-standing containers. Choose clay, metal, or wood planters and place them around the pool to create a sense of greenery and style. Just be sure you place watering into your routine -- or make it the condition for friends and relatives who want to come for a swim. To avoid winter blahs, look for a hard pool cover that keeps the snow up.

Keep weeds at bay

If weeds seem to be taking over try the following weed-busting tips. Where possible, dig weeds out by hand -- but be sure to reseed the lawn, if they are in the grass. In flowerbeds, once weeded spread mulch between the flowers to keep them from re-growing. Cut your lawn a little more often to help grass outgrow the weeds. And between patio stones or in the sidewalk, pour boiling water over the weeds and then fill the cracks with sand.

You can't find the house

If shrubbery has taken over your lot, it's time to get out the hedge clippers. Trim hedges to the bottom of the windowsills; take out any hedges that are truly oversized. If you want to cover an unsightly wall, window boxes or ivy may be a better choice than hedges that seem to have eaten your home.

Small space

If your yard is suffering from its size, here's a tip for you: think vertical! You can create a sense of lush greenery and still enjoy an area to entertain if you use wall space, trellises, and even arbors to allow climbing plants to thrive. If you have a lot of sunshine try clematis or climbing roses; if it's shady consider Boston ivy or, if you don't mind the wait for it to grow, hydrangea.
