Expert Furnace Replacement in Alpharetta, GA

When your furnace starts costing more to repair than it's worth, replacement is the practical next step. A&K Service Inc. handles furnace replacement in Alpharetta from the first assessment through final system startup. We inspect your existing unit, check ductwork condition, and size the new furnace correctly for your home's square footage. Proper sizing matters here. An oversized unit short-cycles and wastes energy. A unit that's too small runs constantly without reaching your set temperature. Alpharetta winters are mild but can drop into the low 30s, and many homes in the area carry furnaces that are 15 to 20 years old and well past peak efficiency. A worn furnace also raises safety concerns, including heat exchanger issues that can allow carbon monoxide to enter living spaces. We remove the old unit, install the replacement to code, and walk you through the new system before we leave. Call A&K Service Inc. to schedule your furnace replacement assessment in Alpharetta.

A&K installed a new furnace for me and a new air conditioner a year later and tune-ups every year. These guys are good. Always on time, always very thorough. Ernest Craig will always be my HVAC guy.
