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 ...
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 ...
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 could put in a non-forced air heating system - ie, hydronic or radiant, using water in pipes to deliver heat. You could use mini-splits for A/C only or for heat and A/C. You only need space for ducts if you need ducts, and there are plenty of houses without ducts... Edit: you may be able to work with a wide, shallow duct so you can have a broad, not too ...
Mini-splits have many advantages, so tossing them out wholesale is a somewhat puzzling response to a house with limited options for running ducts. If you don't like beige plastic boxes (who does, really?) there are several versions that are made to be visually unobtrusive, with the inside unit concealed in a picture frame, or a small inside unit that can be ...
AKA: Dirty Sock Syndrome (paraphrased), caused by the growth of mold and bacteria on the coil. Heat pumps (central HVAC) are particularly susceptible because, unlike conventional heat exchangers, their heating cycles are not hot enough to kill the microbes that thrive on their wet coils during the cooling season. Instead, the temperature is just warm enough ...
Same thing my the system in my house. Uses a MERV 16 5". Smell was the filter itself. Dont know what it picked up, but it was generating its own odor. Whew ! I think it started after I baked a beef roast. which smoked a bit when in the oven. Maybe something in rhe meat ?
