Sounds like a classic compromised leg of your main service. This problem could be anywhere from the connections at the utility transformer on the pole, to the connection taps on the side of the house, to the meter pan, to the main breaker. IMO this is NOT something for a DIY to troubleshoot since you would need to be testing live unfused wires in places ...

After reviewing the spec sheet for the unit i have found that the LX series has a variable speed blower that will allow the unit to operate under low ambient conditions. Is specifies the system can operate down to 20 degrees. Anything below this and the system will not operate. If you do not have the LX unit and do have the standard, the. The unit is not ...

In theory this is what HVAC professionals are supposed to do. In practice, most of them rely on antiquated rules of thumb to size equipment and use existing ductwork, even if it has major problems. A certified energy rater is who you're looking for and who will be able to definitively tell you what you need to know, but you can learn a lot yourself to be a ...

Entirely apart from the high cost of electric resistance heat, (that is, regardless of heat source) a 1969 house is almost certainly going to benefit from insulation upgrades and the boring best bang-for the buck stuff nobody ever thinks is "fancy enough" to go for first - caulking, weatherstripping, and generally reducing air leakage. With the advent of ...

It's all about the temperature/pressure relationship, and how pressure affects the boiling point of the refrigerant. As the pressure of a refrigerant goes up, so too does the temperature and boiling point. When the pressure drops, the temperature and boiling point drop as well. Air conditioning (and some heating) systems take advantage of this, to cool ...

Can you do this? ABSOLUTELY NOT!! Aside from (likely multiple) code violations you will never filter the lint out and will create a dangerous situation inside the furnace plenum, aside from clogging the furnace filter probably weekly.

You'll want to check with your local government. The sale of a house often requires some things to be brought up to current code. What things are required, depends on the local government. For example. In my area, sump pumps are required. If you're selling a house without a sump, you'll have to install one before you can close. A nearby area requires ...

The dryer vent and the combustion vent are one and the same. If you try to use the dryer vent for heating you will have two issues, first excess moisture and second carbon monoxide. Gas dryers get their efficiency by directly venting the combustion into the damp clothes which then by the way of evaporation drastically reduces the temp of the heat. It ...

The bigger issue is that if there are bedbugs in your apartment, the whole building is probably infested. Your best bet is probably to isolate yourself from the bedbugs and set a CO2 bedbug trap. Look into finding a new apartment.

Electric resistance heat is expensive, no way around it. Here are a couple of high-level things you can do to reduce your bill: Common sense: Stop using your fireplace (it's sucking more heat out of the house than it's adding. Free. Conservation: Turn down the heat and wear more clothes. Free. Efficiency: Improve your house's level of air sealing and ...

Do you have a budget in mind for adding the ac? You can use a water-cooled unit, but plan to spend $1500 and up. These units can be hooked up to a water supply (sink, garden hose, etc.) and drained back to a sink, outside, or wherever is available. The heat from the air is transferred to the water - much like a geothermal ac or heat pump works. We use these ...

This is definitely an issue with one of the legs of your main service. This pops up most commonly when the temperatures outside start to change and cause the wires to contract or expand. The power coming in to your house is normally fed by two separate wires, if one of these has become loose, you will see issues on about half the circuits in the house.

Depends on location but 50-55 degrees Fahrenheit is fairly standard.

I had the same problem, tried everything, replaced the switch and the thermopile, no avail. Then finally I removed the pilot light assembly, the top just pops off and using a straw blew a bunch of dust out of it. The result was a better flame on the thermopile which allowed the valve to open, try that.

I would guess that modifying the duct work in a 1920s masonry construction home will be prohibitively destructive and involving removing or damaging irreplaceable trim that contributes to the building's character. Mini split heat pumps: An alternative, which will not be inexpensive but may be significantly less destructive, would be investigating ...

i would suggest having an HVAC contractor visit to examine all of your ductwork. My guess would be there are wholes, gaps, or rips in the ducts whereupon the system in operation is pulling the dust in from wall cavities, basement or attic (depending on where the ductwork runs). Once the contractor (or yourself) seals up and/or replaces any ductwork then ...

If the steel door is of a standard size, see what it would cost to buy another door of the same size. Then ask the landlord if you can replace it with your own door, and cut a hole in that. In the optimal case this would just require lifting the old door off the hinges and the new door in its place. At most you have to unscrew the hinges and move the lock ...

It should be fine. Air conditioners remove heat and dump it outside; sounds like the heat got dumped into the cover. Remove the cover, let the unit cool down, and don't do it again. If it stops working, call a service tech.

It does sound like the biggest opponent the AC is facing is the large picture window. I'm guessing it's just not a well insulated and/or not high-e glass and just letting too much heat in. For starters, close the internal blinds. If that isn't enough, consider some exterior blinds. These aren't terribly expensive and shouldn't be something that the landlord ...

If the camp has internet access, you may want to look into a WIFI-controlled thermostat. Most allow you to remotely monitor and control the temperature through a mobile phone app or with a laptop web interface. This will allow you to have the most versatile control over your temperature settings. The only other piece of equipment you'll need to make this ...

The problem with adding humidity to a leaky home is amount of water vapor air can hold varies significantly with temperature. While 30% relative humidity at 72°F seems dry and harmless in and of itself if you cool this same air to 38°F (let alone -10°F it sometimes get) all of the sudden you have reached 100% RH. The difficulty is making sure ...

The capacitor needs replacement. While it is possible there is a circuitry problem causing the capacitor to overheat (and thus fail like this), it is also possible it was simply time for this electrolytic capacitor to fail while nothing else is wrong. See this photo for a similar failure mode.

What you’re describing sounds like a combination of negative pressure in the compartment that the drain pan connected to and an incorrectly sized p-trap on the condensate drain. The depth of the t-prap has to be greater than the negative pressure in inches of water column of the compartment where the drain is connected to. A t-prap with insufficient depth, ...

If the vent pipes are made of iron based metal or any covered over grate is made of similar material you could go hunting with a magnet.

Looks like you have a gas furnace. If so the furnace will fire and preheat the chamber before the fan engages. This help dissipate any cold air in the ductwork before it blows into the conditioned space. On page 22, Note #12 of your schematics there is a 25 second delay for heating. For cooling there is only two seconds delay. For heating, this would be CPU ...

It is not expected to work, but it might. Many modern compressors have interlocks that prevent them coming on in too-low temperatures. If there's no interlock or heating element, you could also damage or destroy your compressor if you turn it on at too-low temperatures. This is because it is possible to pull liquid rather than gaseous refrigerant into the ...

Reducing drafts are the first place to start. It's your best return on your investment. (as others have said already) The test to do is a "Blower door test". I did one myself with a fairly powerful fan, some plywood and a window. I think I can get my hands on a thermal imaging camera from a friend, but so far I've been able to detect leaks fairly easily ...

One option would be "low-volume, high-velocity" ducted system (manufacturers include SpacePak and Unico) that uses a series of small 2" diameter ducts to distribute air. Depending on the size of your joists, 2" holes may be acceptable. As @Ecnerwal mentioned, mini-splits can be a good option too.

You can either cap the wire with a twist-on wire connector (or similar device), or clip the uninsulated portion of the wire off. Once the uninsulated portion of the wire is covered, you can just tuck it away. To be extra safe, you can disconnect the other end of the wire from the furnace.

If your basement is already mostly comfortable without the problematic supplemental furnace and its ducts, why not spend the money on properly insulating the basement instead? That way it will likely be all the way comfortable when heated from the heat of the main furnace, and then you can fully abandon and/or remove the redundant furnace and have lower ...
