  • A stumper for the HVAC technicians?

    Maintenance & Repairs - 8 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) - 14 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?

Green Living Tops Newest Trends

By Cheryll Gillespie
This year will prove to be an exciting one in the world of home construction, with new materials, new technologies and changes in how we build homes. There is also a shift in how architects are drafting floor plans to reflect the ways in which we are now choosing to live. So what does the future hold?

Green, green and greener. For me, this is perhaps the most exciting trend in the building industry. Green-built homes not only look elegant, but they are comfortable and more economical than past years.


Our homes are also getting healthier. Now, we know more about building products that can literally make you sick. Synthetic materials and chemical additives found in composite wood products such as MDF, flooring materials, glues, plastics and paint, to mention only a few, give off harmful vapours. I am hoping this will be a banner year for organic and natural-based, healthy construction and finishing materials in home construction. The air inside our homes should be the cleanest and safest we breathe. Unfortunately, often it isn't. This year, I'm reminded of the growing number of exotic finishing materials available, such as foreign marbles, onyx, rare stones and exotic granites, special-effect paints, textured glasses, and handcrafted vessels instead of sinks.
 
There is no shortage of creative ideas when it comes to finishing materials. This year you will undoubtedly be asking the host or hostess at many display homes, "What did the builder use in this room?" or "What type of stone is that on that counter top?" or "Where did you find that fabulous light fixture?"
 
Prefabricated construction has matured and is becoming stylish, even with higher-end homes. Expect more builders to support factory-made homes and construction components.
 
If your new home purchase this year is a loft, or a condo converted from an old factory or abandoned warehouse then you are one of the many new home purchasers buying vintage. This trend in taking old dwellings and rebuilding them is not only an eco-friendly concept, but preserves some of our architectural heritage.
 
Architects are designing to suit our changing needs, and this is more prevalent and insightful than ever. Blueprints will reflect the need for flexible spaces. Look for rooms that can be divided — or not — with pocket doors or attractive sliding panels to create versatile open or closed spaces.
 
Speaking of adaptable floor plans, a growing number of two- and three-storey homes will include elevators, allowing us to age at home. We also look forward to wider hallways to accommodate wheelchairs and walkers — smart planning for the inevitable.
 
We will pay more attention to the exterior of our new homes. A strong focus is placed on curb appeal and individuality. Colour plays a major role and will be rich, dark and textured.
 
Past years often saw outdoor spaces and landscaping plans left untouched by the builder. This year, builders and architects take command of interior and exterior rooms, patios and gardens. Outdoor rooms will be incorporated into the home's design. This may include audio and visual equipment, gas fireplaces, full kitchens and bars.
 
The bathroom stands a strong second this year as the most stylish new homes will feature showers with more jets and heads than a carwash, mood light and adjacent dressing spaces.
 
This also will be the year of the "detail," with emphasis on the selection of exotic finishing materials and details that complete a home.
 
One of the most common homeowner complaints has been lack of storage. Look for show homes and blueprints to display fabulous walk-ins from the ensuite dressing rooms and closets.
 
Fully designed garages will have built-in storage and work spaces while craft and storage areas show up in traditionally under-utilized spaces: stairwells, attics and in bonus rooms.
 
Many homes will also include a wine cellar.
