What heating problems come with pre-war Dayton houses?
About 38.2% of Dayton's housing predates 1940. Many of those houses started on a gravity furnace with radiators and were converted to forced air later, and the conversion usually meant squeezing trunk lines into a basement joist bay that was never sized for the job. That is why one room never keeps up in so many of these houses, and why adding return capacity fixes more of them than new equipment does. Ask for the airflow to be measured before anyone quotes you a furnace.
Should the furnace and the air conditioner be replaced together?
Not automatically, but there is a real reason it comes up. The indoor coil sits in the furnace cabinet and the two are matched as a system, so replacing one and keeping the other can leave you with a pairing that does not hit the efficiency either part was rated for. If both are near end of life, doing them together costs less than two separate jobs because it is one visit and one set of connections. If the air conditioner is eight years old and healthy, keep it and say so to anyone who tells you otherwise.
What actually happens during a furnace tune-up?
It should be a list of measurements, not a look. Combustion analysis at the flue, gas pressure at the manifold, temperature rise across the heat exchanger, amp draw on the blower and the inducer, flame sensor cleaned and its microamp signal read, safeties tested rather than assumed, and a look at the heat exchanger itself. Ask for the numbers afterwards. A visit that produces no readings gives you nothing to compare against next year, and year-on-year comparison is most of what a tune-up is actually for.
Why is the house so dry in winter, and does a humidifier help?
Cold outdoor air holds very little moisture, so every air change your house makes in January swaps damp indoor air for dry. The furnace does not cause it, it just moves it around. What you notice is static, dry skin, and gaps opening in hardwood floors and trim that close again in summer. A whole-house humidifier plumbed into the ductwork handles it more evenly than portable units, and it wants a humidistat rather than a fixed setting, because running too wet in a cold snap puts condensation on the inside of your windows.
The vents smell like burning dust when the heat first comes on.
That one is usually nothing. Dust settles on the heat exchanger over a summer of not running, and the first few cycles in autumn burn it off. It should fade within an hour or two of running and not come back. What is not normal is a smell that persists past that, a sharp electrical or plastic smell at any point, or anything like rotten eggs. The last one is the additive put into natural gas so you can smell a leak, and it means leave the house and call the gas utility before you call anyone else.
