  • A stumper for the HVAC technicians?

    Maintenance & Repairs - 7 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) - 12 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?

Starting Seeds Indoors

Annuals and vegetables from seed

By Mark Cullen

Success in gardening is always the result of combining sound gardening practices, grade

A materials and good timing. This is especially true of starting from seed.

Good timing is essential when starting from seed. You have to sow, transplant and set out each variety of plant according to its needs.

It's important to read seed package instructions carefully, and if they are not specific enough for you to understand, ask for professional advice at your garden center.

Some seeds should be started February or before March 15th. These include such favorites as Aster, Carnation, Dianthus, Dusty Miller, Nicotiana, Pansy, Phlox, Portulaca, Salvia, Snapdragon, Celery, Eggplant, Peppers, Watermelon and Tomato.

You have until March 20th to seed Castor Bean, Celosia, Dahlia, Marigold, Cauliflower, Cabbage, Cucumber and Onion.

Anytime between February and the end of March is the right time to start Alyssum, Kohlrabi and Lettuce.

Cosmos, Nasturtium and Zinnia can be started in the first ten days of April.

For the best success rate in starting your garden from seed, always use fresh, high quality seeds, clean and sterilized seeding trays, a light-textured growing medium and the best advice you can get.

There are some seeds which need to be soaked overnight, or even frozen for a few days in order to germinate. Carnation seeds, for instance, require a light freezing for 5 days before planting in order to germinate successfully.

Some seeds (Nasturtium and Pansy) need darkness to germinate, but most varieties need good light to germinate. And all varieties need good light to grow once they HAVE germinated.

There are several seed catalogues available at this time of year. Most catalogues not only provide seed descriptions but growing tips as well, and many offer garden supplies through the mail. There are many free catalogue available up on application from seed companies.

Starting your plants from seed offers some distinct advantages. You can select NEW varieties that may not be available yet in bedding plants. And if you care for your seedlings well enough to bring them to maturity in your garden, you can save yourself some money.

Starting plants from seed may seem like a complicated process at the outset, but once you gain some experience at it, it will become second nature to you.

Experience and good timing are the keys to success!
