The indoor blower and the outdoor unit run on separate circuits. When the fan runs and the air is warm, the outdoor side often isn't running. Possible causes include a failed capacitor, a tripped disconnect, a bad contactor, or a compressor that has shut down on overload.

Turn the thermostat to OFF and the fan to ON so the coil can thaw without loading the compressor. Replace a dirty filter while you wait. Do not chip at the ice — the coil punctures easily.

Twelve to fifteen years is a common range here. The cooling season is long, so equipment logs more runtime hours than the same model would in a milder climate. Annual maintenance can help systems reach the upper end of that range.

It depends on age, the repair quote, refrigerant type, and your current cooling bill. The cost calculator compares five-year cost both ways using your own figures, which is more useful than a general rule.

Homes only — houses, townhomes, and condominiums. Residential equipment is the entire focus of this site.

Square footage alone isn't enough. A load calculation accounts for insulation, window exposure, ceiling height, and duct capacity. Oversized systems can short-cycle and leave a home humid, which is why sizing should come before a replacement quote.

One-inch filters commonly need replacement every 30 to 60 days during cooling season; four- or five-inch media filters typically last six to twelve months. Homes with pets or allergy concerns often need them changed more frequently.

New residential equipment has moved toward lower-GWP refrigerants such as R-454B and R-32. Existing R-410A systems can still be serviced and do not need to be replaced simply because of the change. The refrigerant guide on this site explains the differences and what to ask before buying.
