Air Conditioning and Cooling Services in Meridian, Idaho

The most common causes are a failed run capacitor, meaning the compressor is not actually running even though the fan spins, a condenser coil too dirty to reject heat, a low refrigerant charge, or a frozen evaporator coil caused by restricted airflow. Start with the filter, since it is free to check and causes a real share of these calls. If you can see ice on the refrigerant lines, switch cooling off and run the fan only to thaw it before anything else.

Annually, ideally in spring before the cooling season. In this valley the condenser coil cleaning is the item that matters most, because agricultural dust and cottonwood seed clog coils far faster here than in most places, and a blocked coil makes the compressor work against high pressure all summer. Testing capacitors against their rated values is the other high value check, since a capacitor that has drifted out of tolerance is a cheap spring repair and an expensive July emergency.

Heat rises, and duct systems in two storey homes frequently do not deliver proportionally more air upstairs to compensate. It is one of the most common complaints in valley subdivisions. The important point is that the fix is usually not a bigger air conditioner. It is more often duct modification, airflow balancing, adding return air upstairs, or zoning. That is why we measure static pressure rather than simply quoting a larger unit, because a bigger system on inadequate ductwork spends money without solving the problem.

You can, but it is not a repair. A sealed refrigeration system does not consume refrigerant during normal operation, so if the charge is low there is a leak. Adding refrigerant without locating the leak means paying for the same thing again, usually within a season, and running on a low charge damages the compressor. We locate and repair leaks instead. If someone offers to just top it up without looking for the leak, that tells you something about the work.

Whatever a load calculation produces, based on square footage, insulation, window area and orientation, air leakage, ceiling heights and the local design temperature. Not the size of the unit coming out, and not a rule of thumb per square foot. Oversizing is the most common error: an oversized system cools quickly, satisfies the thermostat and shuts off before it has run long enough to even out temperatures between rooms, producing cold blasts, uneven comfort and extra wear.

Meaningful smoke filtration needs MERV 13 or better, because smoke particulate is very fine. The critical caveat is that a MERV 13 filter in a standard one inch slot will usually restrict a residential system badly, which can freeze the evaporator coil and strain the blower. The right solution is a deep media cabinet with enough surface area to run MERV 13 at a low pressure drop. We can measure your system’s static pressure and tell you exactly what it will support.

Twelve to fifteen years is typical, sometimes longer with consistent maintenance. In this valley the biggest factor within your control is keeping the condenser coil clean, because a compressor that spends every summer working against a dust-blocked coil is under continuous strain. Systems that get annual coil cleaning and routine capacitor checks tend toward the upper end of that range.
