With most pull chain fan switches, you'll need to replace theswitch, though on some models you may be able to reattach thechain. To replace the switch, you will need to know whether itoperates the fan or light. If the switch goes to the fan, you willneed to know how many speeds the fan has. Here's...
Your location matters. If in Florida heat pump in more northern climes furnace & ac.
That will depend on the cost (and availability) of gas in yourarea, when compared to electric costs. It will also depend on theclimate. At very cold temperatures (below 40 F) the heat transferelement of an air/Freon heat pump does not deliver heat, and theless efficient electric heat kicks in. In a...
A commonly used formula is 600-650 square feet per ton. So it wouldbe recommended to use a 2-ton heat pump for a 1300 square foothome. However, other variables are often considered, too, such asthe age of the house.
Yes, gets a nice blaze, as long as it is properly seasoned.
The rule of thumb is 400 sq ft per ton, but that is not always accurate. HVACCALC will show you why.
Hang a blanket over the door and get a small electric heater with a fan. New they should be about $20. Used can be $5. Do anything you can to seal the room from heat loss. Unless the window is insulated, covering it with blankets will help also.

Put in new filter Clean vents Clean air ducts
ANSWER: . Contact the manufacturer and inquire if they repair or replace the units with freon leaks. Also ask them if they can refer a repair shop near the town you live in. Quite simply, putting more freon in it will leak out and it will keep freezing up. Fix the leak.. >>>>. More times than not...
Usually the filter is right on the inside of where the return airduct meets with the furnace. You usually have to take off the sideor front panels of the furnace to gain access to where the filteris. Usually these involve sliding them up and out but it can vary.Check an online owners manual for the...
To open the handle must pull it towards you. The handle has pivotpoints allowing the door to open in steps.
The AC condensing unit needs two 24 volt low voltage control wires,the high voltage will be 220 - 230 volts and requires 3 wires , 2hot legs and a ground. You can buy pre made whips as they arecalled cheaper than making one.
No. BTUs are heat (British Thermal Units) and cfm is a measure of air flow volume (cubic feet per minute)
R12 is almost impossible to buy, unless you go to a large-scaleauto parts supplier like Napa. They won't sell it to you unless youare a certified A/C technician. You can buy R134a easily at otherauto-parts stores, but be careful! If your car's A/C system isdepleted of all refrigerant, you have a...

Contact the manufacturer of the unit. Give them the model andserial number. See if they can send you one via email or mail.
All refrigerants remove and reject heat in the same way theyjust do so at different temperature and pressure relationships, forexample, water at sea level "boils" or changes state at or above212F, we can control the boiling point by adding or reducing thepressure exerted upon it. Water in a 30"...
Look at the control board for any flashing light for a diagnosticcode, without the make and model # I can tell you there are severalareas that can be causing this, low or high water level, hightemps, the flue being blocked or the pressure switch not closingetc.
I have not ever heard of central air being run on anything otherthan electricity. Therefore, having your gas turned off should notaffect it. Central air is run totally by electric. You only need electricityto operate your furnace blower in cooling mode so no gas isrequired.and if your gas is...
There are corner fireplaces and there are corners near fireplacesthat are called nooks.
This means the highest point which the piping attains. typicallyreferring to where trapped air will go and be vented or bled out.
An air trap is where the air is bled out of a system normally,there is also trapped air in some poorly designed systems orsystems with water having recently been added.
A corner electric fireplace is a fireplace that goes in a corner. Electric Fireplaces come in multiple shapes and sizes. You have standard floor models, corner models, wall mounted, TV and Media Mantles, and the kind that go directly into the wall. Corner Electric Fireplaces are made to have...
Transformers will make a buzzing sound when old or getting tired ornear failure, see if it is hot to touch? Measure its amp draw, itshould not be much, a 48 VA transformer will pull 2 amps max only1.8 continuously.
A fireplace that is back drafting is reacting to a negativepressure being created inside the home by a clothes dryer or leakyfurnace supply duct, bath vent or laundry went, water heater orfurnace, all of these devices expel indoor air which under certaincircumstances will create a negative pressure...
Yes if you have electric heat and it is a heat pump. A heat pump isessentially a AC unit that reverses itself to rejecting heatindoors or outdoors.
It varies for each home. A manual J, D, & S should be performedto determine the amount/size of ductwork that is needed.
Most output ranging from 560 to 600 btuh per foot, this is with 170F water temps. I have no way to know your specifics from where Iam.
If installed properly by a competent contractor they are likely no better or worse than any other brand unless you buy a low end builders grade model. Like anything else you get what you pay for.
I'm an old (75) country boy who lived by a fireplace all my life, until I was in my 20's as the only source of heat besides the wood stove in eth kitchen, and I've never heard the corner by the fireplace to have a special name except "the corner by the fireplace." As in, "Stand it in the corner by...
they produce a large current of air that can affect the the way theair feels
Heat rises so a bottom supply will work best.
The pressure may be too high or the orifices obstructed by ash.
It has to do with reflection and how glass magnifies heat. When the sun streams toward the window, the room or person near the window gets hot. Yet, if you touch the glass, the glass itself may feel cool or cold because the colder outside temperature affects the surface of the glass. Next answer:...
Kerosine and heating oil are the same thing
Heaters prior to 1978 had "standing pilots" meaning they were oncontinuously, just like our water heaters still use today, sincethen laws enacted made a standing pilot for California illegal andthe country followed Ca law.
If you have a heat pump it will be on the thermostat, if thethermostat for some reason has been changed to manually wire upemergency heat , remove the thermostat after you kill the power andconnect the red wire too the green and white wire then turn thepower on, you will have heat.

No radiators work best by allowing air flow to rise through them, asmall fan will be better.
Yes both indoor and outdoor fans will operate, the only time 1 willstop in heat mode is in defrost the outdoor one stops briefly todefrost better,
With refrigerant gauges we read the pressures and measure thetemperatures, without that we look at the amp draw and what the airtemps are going in and out,
Heat load calculations need to be conducted for home to determinethe proper size furnace. There is no simple answer to thisquestion. There are a number of factors that can effect what sizeyour furnace should be. Example: square footage, duct work size,insulation factors, windows etc. I recommend...
No, it is preferable to use outdoor air which is then expelledrather than blowing indoor air out so new cold air replaces it.

a woodstove. they are really effective. i have one and it is so warm. you even save money using it instead of your furnace.
Answer . Chances are the compressor is not running. It could be a number of causes:. Compressor is not getting power due to a bad connection . Some AC units have a fan only setting. The switch may have failed and it is stuck in fan mode . The compressor is toasted. . There is a coolant leak and...
The air filter will either be located at your "return" or "intake" grill (both are the same, different terminology only) or at the air handler. If you are talking about a refrigerant filter, you need a "bi-flow" refrigerant filter. Most people mount it nearest to the indoor coil and installed on the...
It depends on the efficiency you are looking for and the metal workthat needs to be done. Contact heating and cooling companies to getestimates.
From the supply lines to install off your main gas line. If this is not done by a qualified person, you must have it inspected by your local codes.
Probably to reduce noise and friction during expansion and contraction.
