Emergency Furnace Repairs

We understand going throughout the night without heat may not be an option. That's why for those exceptionally cold and bitter nights (-15 and below) we give you the best chance for same night service by providing adequate staff for handling your emergency furnace repair. If we don't have anyone available that night, our diagnostic is free the next day.


How often should I have a furnace inspection?

Annual inspections are recommended for most types of furnaces. This is best done before temperatures start to drop, so you can be sure that you’ll be able to enjoy your furnace when you need it. During an inspection, we’ll check for issues that could cause future breakdowns, and recommend replacements for parts that have experienced significant wear.

How can I tell if I need a fix vs. a replacement?

If you don’t have any experience with furnaces, it can be difficult to tell if you need basic repairs or a full installation. Our team members have a lot of experience with all types of furnaces, including those that are decades old. We’ll do what we can to put even the oldest furnaces back in working order, and we can help you make the right decisions about replacement furnaces.

Is it always serious if I smell gas?

If you smell gas, particularly if you believe the source is your furnace, everyone should immediately leave the home and contact emergency services. Gas scents should always be considered dangerous.  Once gas service to the home has been cut off, our repair experts should be able to inspect the furnace or other home appliances to determine if it is the source of the leak.
