Tune-ups that keep breakdowns out of Darke County
We tune up furnaces and air conditioners every season in Darke County, Ohio. You get a written report and photos for your warranty records. Most calls get handled the same day, and someone answers the emergency line at any hour.
Seasonal furnace and AC maintenance for Darke County homes — done right, documented for your warranty, and automatic if you're on the X-Plan.
Not a once-over. A real inspection.
What should a tune-up leave me with?
Numbers. Temperature rise across the furnace, static pressure in the ductwork, superheat and subcooling on the air conditioner, amp draws, and a combustion reading at the flue. Ask for them, and keep them. One year of readings tells you the system is fine today. Three years of readings tells you the compressor is drawing more than it used to and the refrigerant charge is drifting, which is the difference between replacing a part in April and replacing a system in July.
What actually fails most, and would maintenance have caught it?
Capacitors first, by a wide margin, then contactors, flame sensors and condensate blockages. All four are cheap parts and all four are checkable, which is the honest case for maintenance: a weak capacitor reads weak before it fails and gets replaced during a scheduled visit rather than on an emergency one at a different rate. What maintenance does not predict is a compressor or a heat exchanger failing outright, and no honest inspection will promise you it does.
What should I keep, and for how long?
Keep the install paperwork for as long as you own the equipment: model and serial numbers, the install date, and the warranty registration. Keep service invoices for the life of the system, because that is the record a warranty claim asks for. Photograph the data plate on both the indoor and outdoor units once and keep it on your phone. When something fails on a Sunday, being able to read the model number out over the phone is the difference between a part on the truck and a part on order.
Should I cover the outdoor unit for winter?
Generally no. A heat pump must not be covered at all, because it runs all winter. An air conditioner does not need one either: the unit is built to sit outside, and a full wrap traps moisture against the metal and gives mice somewhere dry to nest in the wiring. If you want to keep leaves out of the top, a piece of plywood weighted on the fan grille does that without sealing the cabinet. Take it off before the first cooling call in spring.
