This month’s troubleshooting situation involves an air-to-air package unit heat pump that is approximately six years old, and the customer’s complaint is that, rather than providing cooling, it’s just blowing warm air.
In this month’s troubleshooting situation, our customer’s description of the problem is “not cooling” and “blowing warm air,” and the equipment that is supposed to keep this residence comfortable is a split system that has been in service for 16 years.
Looking ahead to the upcoming cooling season, the equipment in this troubleshooting situation is a split system that’s approximately eight years old, consisting of a gas furnace that provides heat in the winter and a condensing unit and A coil to provide summer cooling.
In this month’s troubleshooting problem, we have a customer who can only tell us that the equipment that serves their small office “isn’t working.” When you arrive, you confirm that the building temperature is far from the thermostat set point even though the indoor fan motor is operating normally and the return air filter is clean.
Our troubleshooting problem involves a split system heat pump in which the outdoor unit is operating in an 85°F ambient, and when you arrive in response to the customer’s no cooling complaint, you find the indoor fan operating normally, and you also note that 240 volts is read at L1 and L2 of the outdoor unit.
In this month’s troubleshooting situation, our customer has called to say that the roof-mounted gas pack on their 1,500-square-foot home isn’t keeping them cool. Their specific description of the problem is that they “can’t feel any air” coming from the supply registers.
In this month’s troubleshooting situation, the customer hasn’t called because their HVAC system has stopped cooling. You’re there because they’ve requested a preventive maintenance check of the five-year-old equipment to determine if there are any potential problems that would affect the system performance in the future.
An HVACR service manager or service company owner in pursuit of excellence should be actively involved in the maintenance and almost-constant evolution of their website. Approaching it via a blend of the available options makes it manageable.
In this month’s troubleshooting problem we have a homeowner who has attempted to repair his own equipment, and he has replaced two components. The original symptom of the split system sitting dead still exists.
In this month’s troubleshooting situation, we’re taking you to a school, but not to the equipment room of the main building. Instead, it’s a modular classroom (similar to a double-wide manufactured home) that is brand new, and employs a heating/cooling unit that mounts on one end of the building.
