Reliable, efficient heat for years to come. We size your new Rheem furnace correctly, handle the gas connections ourselves and back every installation with our 100% satisfaction guarantee.
Replacing a furnace is a big decision, and it's one you shouldn't have to rush in the middle of a cold snap. Cool Mountain Air helps you plan the replacement, choose the right system and get it installed properly. Every installation starts with a load calculation so your new furnace is sized for your home, not just copied from the old one.
As a Rheem Authorized Dealer, we install Rheem furnaces for homes and businesses across Northwest Georgia. Because we also do gas line work, we can handle the whole job in-house, from the gas connection and venting to the thermostat and final startup, without bringing in another contractor.
Every installation is backed by our 100% satisfaction guarantee on installations. We're family-owned, Georgia licensed and have been keeping Northwest Georgia homes warm since 1991.
An aging furnace usually tells you it's ready to retire. Here's what to look for.
Many furnaces last 15 to 20 years or more. Past that range, efficiency drops and breakdowns become more likely.
If you're paying for repairs every winter, that money is often better put toward a reliable new system.
Older furnaces lose efficiency over time and cost more to run every month.
Cold rooms, long run times and a system that can't keep up are signs your furnace is wearing out.
A furnace that's too large heats the house in quick bursts, short cycles and wears out early. One that's too small runs constantly and never quite keeps you warm. A proper load calculation looks at your home's size, insulation, windows and layout to get the size right.
Installation quality matters just as much. Correct gas pressure, proper venting, good airflow through the ductwork and a careful startup are what make a new furnace safe, efficient and reliable for years.
If you also have central air, we'll talk through whether it makes sense to replace the furnace and air conditioner together, or whether a heat pump paired with a gas furnace is a good fit for your home.
Every furnace installation from Cool Mountain Air includes:
AFUE stands for Annual Fuel Utilization Efficiency. It measures how much of the fuel a furnace burns actually becomes heat for your home. The higher the AFUE, the less fuel is wasted. We'll explain the efficiency options available and help you choose what fits your budget.
It depends on your home's square footage, insulation, windows, layout and ductwork. We perform a load calculation instead of guessing or simply matching the old furnace, which may have been sized wrong to begin with.
Most residential furnace replacements are completed in a day. Jobs that need gas line changes, new venting or ductwork modifications can take longer, and we'll give you a clear timeline up front.
Yes. We do gas line installation and repair, so we can handle the gas connection for your new furnace ourselves. See our Gas Line Services page for more.
Not always, but it's worth considering if both systems are aging. Replacing them together ensures the indoor and outdoor equipment are properly matched. We'll lay out the options and costs so you can decide.
