A few questions before you call anyone
How many quotes should I get before replacing a furnace or AC in Dayton?
Two or three. Full system replacement is among the largest single home expenses most people face, and pricing for identical equipment varies widely. Ask each contractor to explain the sizing calculation, not just quote a unit.
Do HVAC contractors need a licence in Ohio?
Ohio licenses HVAC contractors through the Ohio Construction Industry Licensing Board for most new-construction and commercial work, while much routine residential service falls outside it. Ask each contractor directly about licensing and insurance.
When should I schedule HVAC work?
Spring and autumn. Booking a furnace tune-up before the first cold snap or an AC check before the first humid stretch keeps you out of the emergency queue — and several contractors above, including Butler and EnviroControl, list 24-hour availability when it genuinely can't wait.
