BAY ST. LOUIS HEATING REPAIR
QUESTIONS ANSWERED.

It's cold and my heat is out. How fast can you get here?

Same day. Heat emergencies during a cold snap get priority dispatch across all 12 cities we serve. Call (228) 265-8609 and we route the nearest available tech.

Do you charge extra for after-hours heating repair?

Yes. Service calls run $125 after 5 PM, on weekends, and on holidays. Standard rates apply the rest of the time, and we'll quote the rate before we dispatch.

Do you service heat pumps and gas furnaces both?

Yes, and electric strip heat, hybrid dual-fuel systems, and mini splits in heat mode. All the equipment types you'll see on the Coast.

My CO detector went off. What now?

Get everyone outside first, then call us at (228) 265-8609. We'll dispatch immediately, and we'll bring calibrated CO testing equipment. Cracked heat exchangers are the usual cause and we'll red-tag the unit if unsafe. Do not run the furnace until we've inspected.

How do I know if I need repair or replacement?

Age of unit, cost of the repair, and how many issues you've had this season. Rule of thumb: if repair exceeds 40% of new unit cost on a 12+ year old system, replacement usually wins the math. We'll quote both.
