Descaling promptly is a service. Ignoring the code for a year is a heat pump, which is the most expensive part in the machine. **Heat.** A refrigerator condenser here works against a warm kitchen for more months of the year than the same unit anywhere north, and near the water salt shortens the coil and the fan motor as well. Cleaning is seasonal rather than annual, and it prevents more expensive repairs than anything else on this list. ### The filters nobody knows about - The washer’s pump filter, behind the flap at the bottom front - The dryer’s secondary filter, and the condenser unit on models that have one - The hood’s charcoal filter, if it recirculates — which in a condo it probably does ### No obligation attached A maintenance visit ends with a short written note on anything that looks like it has a season left in it. That is information, not a quote. Knowing a gasket is on its way out is worth more than being sold one on the spot.

Acting on it costs a service; ignoring it for a year costs the assembly. Condensers and coils Refrigeration in this climate runs against a warm kitchen most of the year. A packed condenser is behind more temperature complaints than any single component. Every filter in the house Dishwasher filter, washer pump filter, dryer filters, hood grease filters, refrigerator water filter. Five appliances, ten minutes each, and most people know about two of them. What we found, written down A short note on anything that is on its way out, with no obligation attached.
