Heating and cooling systems rarely fail politely, and in Evanston, IL, a breakdown usually arrives on the hottest afternoon or the coldest night of the year. What surprises most homeowners is how many different failures produce the same symptom. A system that runs but never reaches temperature might be fighting a weak run capacitor, a pitted contactor, a low refrigerant charge, a dirty flame sensor, or simply a filter so clogged the blower is starving for air. A system that will not start at all could be a tripped float switch on a backed-up condensate drain, a failed transformer, a bad thermostat, or a control board that has stopped sequencing the equipment.
The repairs homeowners call us about most are AC Repair and Furnace Repair. If something has stopped working, start there.
