Emergency HVAC FAQs
What can I do to prevent HVAC emergencies?
Annual maintenance is the best way to prevent sudden HVAC failures. Scheduling regular tune-ups, changing air filters, and keeping your system clean can extend its lifespan and reduce the likelihood of breakdowns. For the best results, invest in our Comfort Club maintenance program. We’ll help keep your system running smoothly year-round.
What does “Emer” or “Em Heating” mean on the thermostat?
The term “Emer” or “Em Heating” on a thermostat usually stands for “Emergency Heat.” It indicates that the heating system is using its backup or auxiliary heating source instead of the primary heating source.
Using emergency heat continuously can lead to higher energy consumption and increased heating costs, so it is advisable to use it sparingly or only during extreme weather conditions. As soon as you can, call our professional team for an emergency repair.
What should I do if my AC is leaking water?
A leaking AC unit could be caused by a clogged condensate drain, frozen coils, or a refrigerant leak. Ignoring this issue could lead to water damage and system failure. A qualified technician can diagnose the cause and make the necessary repairs.
Is it safe to run my furnace if I smell a burning odor?
If you smell a burning odor when your furnace is running, it could indicate dust burning off the coils, an overheating motor, or even an electrical issue. If the smell persists or is accompanied by smoke, turn off the system and contact our team immediately for a furnace repair service.
