Common furnace questions

How quickly can you respond to a no-heat call?

For no-heat emergencies we prioritize same-day service and offer 24/7 emergency response across Macomb County. Call (586) 366-HEAT and we’ll get a technician to you fast.

Should I repair or replace my furnace?

As a rule of thumb, if your furnace is over 15 years old, needs a costly repair, or your energy bills keep climbing, replacement often saves money long-term. We give you honest options either way — never pressure.

How much does a new furnace cost?

It depends on the size and efficiency of the system your home needs. We provide free, up-front in-home estimates and flexible financing so you can choose what fits your budget.

How often should I service my furnace?

Once a year, ideally in the fall before heating season. Annual tune-ups improve efficiency, catch small problems early, and keep your manufacturer warranty valid.
