Expert Furnace Installation in Alpharetta, GA

A&K Service Inc. has served Alpharetta and the surrounding North Fulton County area since 1992. Our furnace installation service covers everything from load calculation and ductwork inspection to equipment selection, connection, and post-install testing. Alpharetta sits in a humid subtropical climate with mild but sometimes unpredictable winters. That means your furnace needs to be sized accurately, not oversized or undersized. A system that is too large cycles on and off too often and wastes energy. A system that is too small struggles during the occasional hard freeze that hits North Georgia. We assess your home's square footage, insulation, and existing ductwork before recommending any equipment. We also check airflow paths and humidity factors that affect how heat moves through your home. Once the right system is selected, our technicians handle the full installation and run all safety and performance checks before we leave. Call A&K Service Inc. to schedule your furnace installation in Alpharetta.

Furnace Installation FAQ

Common questions about furnace installation in Alpharetta, GA.

A furnace that is more than 15 years old, runs unevenly, or drives up your gas bill each winter is a strong candidate for replacement in Alpharetta. A technician can inspect the heat exchanger and key components to help you decide.

Furnace size depends on your home's square footage, insulation quality, ceiling height, and ductwork condition. A load calculation gives you the accurate number so you avoid buying a system that is too large or too small for your Alpharetta home.

A&K Service Inc. handles the complete furnace installation in Alpharetta, including removal of the old unit, connection of the new system, and all safety and performance checks. You do not need a separate contractor.

Existing ductwork is inspected before installation to check for leaks, blockages, or sizing issues that would reduce heating performance. Repairs or modifications are addressed as part of the installation process.

A gas furnace delivers strong, consistent heat and handles the occasional hard freeze that North Georgia winters bring. It is a reliable option for Alpharetta homes that already have a natural gas connection.

Annual maintenance is the standard recommendation to keep a furnace running at rated efficiency and catch small issues before they become larger problems. Alpharetta's humid climate also makes filter checks important for consistent airflow.

Great company to work with. We had a good experience working with them. Professional, honest and upfront on expenses and work required to be done. Got two HVAC units on two separate properties. Ernest serviced and repaired both. I even signed up for annual service contract.

alexandra moreno Google review · August 2026

I was being told half truths / half lies by one of the big HVAC companies and unsure of my options. A&K was referred to me and I was so impressed by their honesty. They explained all the options, the pros / cons, and price of each. Once I made my choice, they got me on the schedule quickly. I was so impressed with them, I will also be using them for ongoing maintenance. Strongly recommend!!

Christine Law Google review · August 2026

The crew arrived promptly (early in fact) and got right to work. They were very polite and professional. The work was completed in a timely manner, the work area was clean (except for a few loose screws) and the trash was removed. Highly recommended this company.

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.
