Common questions

How often should I have my furnace serviced?

Once a year, ideally in the fall before the heating season. A tune-up catches small problems early and keeps the system running efficiently.

My furnace stopped working. What should I check first?

Check that the thermostat is set to heat, the furnace switch is on, the breaker hasn't tripped and the filter isn't clogged. If it still won't run, give us a call.

Do you give quotes before starting work?

Yes. We'll explain your options and the price before any work begins.
