01
Heating Repair

Furnace Installation and Replacement
Whether your furnace has reached the end of its service life or you're upgrading for better efficiency, MTN Air handles furnace installation for all major brands and system configurations. Synchrony financing is available for qualified replacements.

What Your Heating System Is Trying to Tell You
Most heating problems fall into one of three categories: something a repair visit can resolve, a system that's past the point where continued repair makes financial sense, or an upgrade worth evaluating before the next heating season. Match what you're seeing below.
- System turns on but produces little or no heat: Usually a filter, component, or fuel supply issue best addressed with a heating repair visit.
- System won't start at all: A thermostat failure, tripped safety switch, or ignition problem — each one diagnosable and fixable with a diagnostic repair call.
- Furnace making banging, rattling, or squealing noises: Mechanical wear, a loose component, or a heat exchanger issue producing an audible warning before a breakdown.
- Furnace is 15 or more years old and increasingly unreliable: At this stage, furnace replacement often delivers better long-term value than continued repair investment.
- Energy bills climbing without a clear cause: A sign of efficiency decline that often points to a repair need or a system approaching the end of its useful life.
- Considering a switch from gas heat to a heat pump: Worth a real conversation before your next system replacement decision.
Our Availability Is Built for Georgia's Unpredictable Weather
North metro Atlanta winters are real. Temperatures across the region regularly fall into the 20s and 30s, and cold snaps can arrive faster than any forecast suggests. A heating system failure on one of those overnight lows is a genuine problem, and it often happens on the weekends, holidays, and late nights when most companies aren't available.
MTN Air is available every day of the year. After-hours service requests can be booked through our AI assistant, which schedules next-day appointments any time. You reach MTN Air directly, not a dispatch service passing your information along.
The Same Local Team, Every Time You Call
MTN Air is a locally owned HVAC company. When you call for furnace service in Alpharetta or a heat service call in Duluth, you reach the same company that's operated in north metro Atlanta since 2004 — with the same service team, not a rotating cast of contractors dispatched by a call center.
That continuity matters when something goes wrong. A technician familiar with the area, the equipment, and your system's history gets to the right answer faster than one seeing it for the first time. MTN Air's team has spent more than two decades building that familiarity across north metro Atlanta.
