FAQs
Is a broken furnace an emergency?
Trouble with your furnace can constitute an emergency if it’s cold enough outside — a cold home becomes a risk to people and property past a certain point. Trouble with your furnace that leads to gas leaks, water leaks, electrical issues, ventilation problems, and other dangers are emergencies no matter the season.
Why is my boiler leaking?
Boiler leaks can occur due to corrosion, damaged seals and valves, and similar issues. You might also see water leaking from a pressure relief valve, which indicates other problems to be resolved but isn’t a leak in the same sense.
Why won't my ductless mini-split turn on?
Ensure the breaker hasn’t tripped, either at your electrical panel or internally. You’ll also want to make sure the thermostat is set to what you meant to set it to and that your filter isn’t so clogged that air can’t flow. Beyond that, you’re probably looking at a more complicated problem that warrants professional attention.
