  • 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) - 13 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) - 20 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?

Wood Stoves

Burn Seasoned Wood

Always burn seasoned wood- that means it has been split, stacked and covered for at least 8 months. Using greenwood means a cooler fire in your woodstove and flue, thereby giving you a greater chance of creosote buildup. So beware!!

Stove Ashes

Coal ashes are toxic to plants, but wood ashes are great for your plants and garden. They help neutralize soil acidity. You can use any type of ash to provide traction on icy walks and driveways!

Treated Wood

A word of caution to all wood burners: Think before you throw any treated wood into your wood stove or furnace! This wood produces very toxic gases and ashes when burned. Play it safe and dispose of treated wood in an approved landfill.

Chainsaw Safety

Just a few rules to remember when using the chainsaw this fall.
  • Never cut when standing behind the saw.
  • Keep your left elbow straight, not bent, to help control kickback.
  • And wear a hard hat, goggles or visor and earplugs.

Firewood

If you are thinking about burning firewood this winter how do you determine whether the effort will be worthwhile? A shipment of 150 gallons of oil give about the same BTU’s as a cord of wood. Therefore, using hardwood you shouldn’t pay more per cord than 150x’s the price of oil per gallon. ( E.g. Oil at $1.00 / gallon, a cord of wood should cost no more than $150 ).

One Cord Of Wood Equals:

A pile of wood equals 4x4x8 ft. If you take all the air out of a cord of wood you end up with 500 board feet. This could be turned into any of the following:
  • 71/2 million toothpicks
  • 250 copies of the Sunday New York Times
  • 460,000 personal checks
  • 30 rocking chairs, or
  • 12 large dining room tables



Water Heater-

Heater Tlc

To help prevent sediment buildup in your water heater, drain enough water from the water heater until it runs clear. Try to remember to repeat this procedure about every 2 months for better heater efficiency during the heating season.

Wrapping

A simple way to save about $20/year is to wrap your water heater with an insulating blanket. If you aren’t sure that your heater needs the blanket, just feel the tank carefully. If you notice any warmth, wrapping will help keep that heat in, instead of going into the air, therefore saving you money!




Furnace

Savings On Furnace Service

You can possibly save some money by having your furnace cleaned and serviced during the off-demand summer months. Check into having your oil tank filled now also, when the prices are generally a bit lower.

Furnace Cleaning And Tune-Up

Late summer and early fall is a good time to schedule a technician out to the house for the annual furnace cleaning and tune-up. This alone can increase your heater’s efficiency up to 20 %! A savings for the upcoming winter heating bills!

Winter Oil Deliveries

The wind is howling and snow in piles and the oil man is due with a delivery of heating fuel. Where is that oil pipe? Buried under a snow pile?
Plan ahead and avoid this problem. Just place a brightly, colored flag near your filler pipe so the deliveryman can find the pipe with no problems.


Heating Leaks

Want to save some money?

Check out your home’s electrical outlets and switch boxes for air and heat leaks. You can effectively plug those leaks with inexpensive foam gaskets and plastic outlet covers, found at your local hardware store.

Buttoning Up For Winter Weather

Time to buttonup the ole’ homestead for the cool winter weather. Don’t forget to cover your through-wall air conditioner on the inside and outside. Caulk around the clothes dryer exhaust ports. Also, make sure bath and kitchen exhaust fans are operating properly.

Heating and Cooling System

  • Save on energy costs by setting temperatures at 78 F for summer; 68 F for winter. Constant resetting wastes energy.
  • Close supply registers in rooms not in use; also close doors to these rooms.
  • Since hot air rises and cold air falls, in the summertime close some first floor supply registers, and open some upstairs; do the reverse in the winter.
  • Be sure supply registers and air returns are not blocked by draperies, furniture or other objects.
  • Check your heating/ air-conditioning filter at least twice each season. If it's dirty, clean or replace. If you have lots of traffic from active children and pets, check air conditioning filter monthly in summer.


Insulate Around Windows

One other heating or should I say heat saving tip is, in older homes I have found it very easy and economical to take the trim off around the windows and stuff insulation or purchase that expanding foam spray and seal around the windows . I have noticed a big difference in the comfort level and when it is -30c outside you sure notice the difference with the amount the furnace operates . The cost of doing this little job for me was only about $10 dollars for the whole house and I bet it saved me $50 in my heating cost over one winter.

Automatic Door Sweep

Many rooms have carpeting now-a-days resulting in doors to have some necessary clearance to open and close properly. This opening under the doors can cost some loss in house heat in the winter months. Try installing a door sweep, it works by lifting up whenever the door is closed, thereby keeping much warm air in and cool air out!

Caulking

Cracks and joints in your home’s exterior always open up in the winter and therefore cause heat loss. When the temperature cools to around 40 degree F. this fall, the joints begin spreading out. Now is the time before its to cold to work outside and the caulking will still set to fill in those cracks and spaces.

Insulation

Believe it or not, today’s average well-insulated home loses 1/5 of its total heating bill to the earth and air surrounding the basement. The average homeowner can save $140 each year by insulating their basement. A low-cost job that most people can do themselves.

Hypothermia

Hypothermia is a life-threatening condition in which the body temperature drops below the normal 98.6 degrees F. from exposure to the cold. Indoor air temperature doesn’t have to fall below freezing to cause hypothermia. Therefore, make sure at risk family members, (e.g. Elderly, and babies), wear several layers of loose clothing and have plenty of bed covers at night.


Ceiling Fans

Winter-Reverse Direction

Save some money on your fuel bill by using your ceiling fan now that you’ve turned on the furnace for the winter heating season. Run the fans in reverse and set the speed control on LOW. The fan will help drive the rising warm air that collects near the ceiling, back down towards the floor-where people need it most to stay warm!


Smoke Detectors

Yearly Check

Now that heating season is upon us, it’s a good idea to replace all smoke detector batteries. If its easier to remember pick a special day each year to replace your batteries, (e.g. Birthdays, special holiday, etc.).


Winterize Summer Home

Closing Up Summer Residence

Now with the cool weather approaching its time to winterize the summer residence. To protect plumbing against freeze-ups, turn off the water at the main valve, then open all faucets and drain the system at the lowest point. Then flush all toilets, and put ethylene glycol antifreeze, (or winter windshield washer solution), into the remaining water-filled plumbing traps,( like the bathtub).

Winterizing

Be sure to check the following before chilly weather sets in:
  • Forced Air Systems - clean or replace filters. Hot water or steam- check valves, pumps.
  • Plumbing -Drain water from exterior faucets and pipes. Store hose.
  • Windows and Doors - Check paint on sashes and frames; repair or replace caulking, weather-stripping and glazing around the glass.
  • Fireplace - Make sure damper works and chimney draws; clean flue and spark arrestor.
  • Gutters and Downspouts - Clean before first snow. Clogging causes ice dams, leaks and roof damage. If snow-melting cables are being used, check for damage.
  • Sashes and Doors - If insulated glass fogs, replace it.




Energy Savings

Save On Your Heating Bill

Lower your thermostat by one degree F. and you will reduce your heating bill by 2%. Try maintaining 68 degrees as an average daily temperature, with lower temperatures at nighttime. Also, lower the thermostat if you will not be home during the daytime hours.

Hints To Save Your Money This Winter:

  • Try to minimize the number of times that you open your doors to the outside weather.
  • When not using the chimney, remember to shut the flue.
  • Insulate walls and attic areas properly. Batts of insulation added to your attic is an easy do-it yourself project.

Draperies

Open your drapes in the cool weather to let the sunshine in during daylight hours. This will help to warm up the house. Then draw the draperies at night to help retain the heat.
Also, keep draperies away from radiators, so the warm air has a chance to circulate throughout the house.

Summer Tips

Try to limit the amount of heat entering your house during the summer. Try not to use lights and appliances during the hottest part of the day-they generate more heat! Covering your windows with drapes or awnings will help keep the house cool. Every little bit will help and minimize the use of your air conditioner! That means you save money!!!

Save While On Vacation

If you are soon off on vacation, take a few minutes to unplug small and large appliances not needed. Also, turn water heater and air conditioner to their lowest settings. Backing up your computer is probably a good idea, in case a power outage occurs while you are gone.

Beat High Fuel Bills

Installing programmable thermostats to automatically coordinate your home’s temperatures with your day-to-day patterns can help in the lowering of your yearly fuel bill.

Winter Tips

  • Try to minimize the number of times that you open your doors to the outside weather.
  • When not using the chimney, remember to shut the flue.
  • Insulate walls and attic areas properly. Batts of insulation added to your attic is an easy do-it yourself project.
  • Lowering your thermostat by 1 degree F. will reduce your heating bill by 2%. Maintaining 68 degrees is an average daily temperature, with lower temperatures at nighttime. Also, lower the thermostat if you will not be home during the daytime hours.
  • Use ceiling fans set at slow speed to push the warm air away from the ceiling and move it around your rooms. Everyone will feel the warmth and be more comfortable!
  • Try to use the sun when out! Open windows on southern and eastern exposures throughout the daytime hours. Remember to close shades before sun sets to keep the heat in the house.

Try Your Own Energy Audit

  • Measure your insulation, if you have less than a foot, you want to add more to have at least 12 inches of fiberglass blanket insulation. Every inch saves on your heating bill!
  • On a windy day, light a candle and carefully hold it near phone outlets, doors, windows, plumbing fixtures, attic doors, cable outlets. You are testing for drafts! Seal up any large openings with cauling or weather-stripping!
  • A properly maintained heating and cooling system uses 10% less energy than a neglected one--spend the extra time and save some money also!
