Two out of three bedroom wall units don't seem to be working anymore as well as one in a first floor office. It's January in New England so they should be heating! Any suggestions? Or should we call in a professional? Thanks!|||sounds like a job for a pro here if they are electric, check the circuit breaker that supplies the power to the units. if the breaker is open (needs reset), you have a problem an electrician needs to check out. if gas, you may have bad igniters or gas valve problems. call a heating repair company. hope this helps
