Our technician responded to a call for two HVAC systems that weren't working properly in McKinney, TX. The downstairs heating system had stopped working because of faulty limit switches. These safety switches help protect your furnace from overheating. When they malfunction, your heating system shuts down to prevent damage.
The second issue involved a mini split system in the detached garage upstairs. This unit wasn't running because the power had been turned off. After restoring power to the system, it started up and began operating normally again.
Lovejoy HVAC was able to diagnose both problems quickly and get the heating system back online. Regular maintenance can help prevent limit switch failures and catch other potential issues before they leave you without a working system.
