Lennox Split System Heat Pumps in Plymouth – Power to the System.
To begin troubleshooting, power to the system needs to be turned off. Failure to take this simple step could result in serious injury. This is done by flipping the correct switch on the building’s breaker box. The box can generally be found outside toward the back of the building.
The next step in HVAC troubleshooting is to closely inspect the unit and its parts. Although different steps will need to be taken for different problems, examining the system may give a good indication of where any issues may lie or where they may be forming. Maintenance may be done on parts that are wearing down before any additional problems occur.
Split System Heat Pumps in Plymouth – HVAC Troubleshooting.
Depending on the issues at hand, the next HVAC troubleshooting steps may require one of several things. If the system is making a knocking or rattling sound, check the radiator and hoses. These should slope back toward the boiler. If they slope in a different direction, this will need to be fixed to improve function and eliminate bothersome noises.
If the system seems to have a low water level, close the water supply valve connected to the system. Water levels should be monitored for the next several days and if levels drop dramatically, it may indicate that the pipes have a leak. In most cases, a professional will need to be called to fix the leak.
