How long does AC installation take?

Most AC installations in Sandy Springs homes are completed in one day. The crew removes the old equipment, installs the new system, and tests everything before they leave. More complex installations that involve ductwork modifications may take an additional day.

How do I know what size AC I need?

The right AC size depends on your Sandy Springs home's square footage, layout, insulation, window exposure, and other factors. A technician performs a sizing assessment to recommend the right capacity. Getting the size right is critical for both comfort and efficiency.

Will a new AC system lower my energy bills

Modern AC systems are significantly more efficient than older models. If your Sandy Springs home's current system is aging, a new high-efficiency unit should reduce cooling costs noticeably. The exact savings depend on the age and condition of your current system.

Can I keep my existing ductwork with a new AC?

In most cases, yes. If your Sandy Springs home's ductwork is in good condition, a new AC system connects to the existing ducts. The technician inspects the ductwork during installation and will let you know if any repairs or modifications are needed for the new system to perform properly.

What happens to my old AC unit?

The installation crew removes your old AC equipment as part of the job. The old unit is hauled away and the refrigerant is recovered properly. You don't need to arrange separate disposal for your old system.

AC Installation and Replacement in Sandy Springs, GA

One Hour Heating & Air Conditioning® of North Atlanta

AC installation in Sandy Springs gives your home a modern cooling system designed to handle Georgia's demanding summers. Whether your current system has reached the end of its life or you're looking for better cooling performance and efficiency, a properly installed AC makes a real difference in comfort.

Why Sandy Springs Homes Need AC Replacement

Many homes in Sandy Springs were built in the 1960s and 1970s as ranch-style family homes, while others are 1980s subdivisions or newer townhomes and condos. The original air conditioning equipment in those homes has long since been replaced — some more than once. Whether your Sandy Springs home is one of the classic ranch homes or a modern condo around the Perimeter, an air conditioner that's aging loses cooling capacity, runs less efficiently, and breaks down more often. If your Sandy Springs home's AC struggles to keep up on the hottest days, costs more to run each year, or needs frequent repairs, it's probably time for a new system.

Choosing the Right AC System for Your Home

The right AC system for your Sandy Springs home depends on the size of the house, the layout, the condition of your ductwork, and how much cooling the home actually needs. A system that's too small won't keep up on hot days, and one that's too big cycles on and off too quickly, leaving the house humid and uncomfortable. A technician evaluates your home's specific needs — room count, sun exposure, insulation levels, and existing ductwork — and recommends a system that's the right fit. Modern AC systems are significantly more efficient than older models, which means better cooling performance and lower energy bills for your Sandy Springs home.

What AC Installation Includes

Professional AC installation in Sandy Springs covers the complete job — removing the old equipment, installing the new outdoor and indoor units, connecting refrigerant lines, verifying electrical connections, and testing the entire system to make sure it's cooling properly. The installation crew also checks your ductwork for obvious problems that could affect the new system's performance. For Sandy Springs homes with older ductwork, addressing duct issues during installation ensures you get the full benefit of the new equipment. After installation, the technician walks you through the system and makes sure everything is running right before they leave.

About Sandy Springs

Sandy Springs' housing reflects the evolution of North Atlanta construction — from ranch homes and colonials built in the 1960s and 1970s to subdivisions from the 1980s and 1990s, to the newer townhomes and condos being built today. Neighborhoods like Riverside, Mount Vernon, River North, and Chastain Park area each have their own character, but they all require reliable cooling during Georgia's hot summers. Finding the right AC system depends on understanding the specific needs of older ranch homes versus newer construction.

Quick service and got our lack of heat solved.

We had our heating system stop working during the extreme snow storm, and this company responded quickly. Joe Bonness, who is an expert technician arrived on time, diagnosed the issue fast, and fixed it efficiently. He explained everything clearly and made sure the heat was working perfectly before leaving, even though it was late around midnight. We are very grateful for the quick and professional service during such freezing weather. Highly recommend their service!

Huge thanks to my neighbor Chris for coming over late at night to fix my AC unit when it stopped working. I caught him and his family on the way out and told him my problem. He ended up leaving his plans early and took the time to figure it out and got it running again quickly. It meant a lot that he was willing to help out so late. He even gave me a few tips to look out for in case anything else happened. Super knowledgeable and a great neighbor to have! Give that guy a raise!!

Tim was great. I can’t say enough good things. He came out to do a routine maintenance and unfortunately, I had to replace my furnace due to wear and tear. This happened on Friday, and he was at my house bright and early Monday to install the new furnace. He was pleasant the entire time, and very informative throughout. Thank you so much.

I will start by saying that KC was very professional explaining all aspects of the whole job that his team was going to do as far as to what we needed concerning a furnace rather we should repair or replace the existing furnace which by the way was 26 years old. Zo the service installer was quite thorough with the entire job, also Areej another technician did a spectacular job with cleaning all of the air ducts with detailing each step of the way up to and including the dryer vent as well a fantastic job was done. Although the job was extended one extra day was not a problem the problem came about when they informed us that they were going to return the next morning by 10am and by 11am we hadn't heard from them when a simple courtesy call with an eta would have gone a long way instead of me having to place a call to them. Overall the job was complete with a new furnace that was installed and the job was well done.p I would highly recommend One Hour Heating & Air Conditioning of Naperville.

Daphne came out for our semi-annual AC checkup and did a fantastic job. She clearly explained the condition of our unit and answered all of my questions in a friendly, easy-to-understand way. After receiving great service both times the company has visited, I signed up for their membership program. The price is very reasonable and the service has been outstanding. Highly recommend!

Repair tech was fantastic and did a great job. Also, they looked into the warranty information of my unit to give me a partial refund. But, extra fee for weekend work was not mentioned when I called to have a tech come out.

I called because my unit went out early Sunday morning, they came out that day, did the repairs and a full service to get my unit up and running the way it should be, my a/c never blew this cool since I first got the unit! Stephen, was a awesome technician and went over everything thing with me, I learned things about my unit I never knew, thank you so much, I would recommend River City One Hour Air Conditioning and Heating for anyone needing a/c and heating services.

Joseph was personable, professional and efficient. You have a good guy on your team. I have not had many good experiences with One Hour with not getting a call back and waiting long periods of time to get answers for service, etc. that’s why I’m no longer a member but having to get my filter for my furnace only through one hour I had no choice. Joseph was refreshing change.

Anthony was great and was a pleasure to be around. He has a great disposition and even helped me fix a door I was working on! He identified an issue with our unit that was costing us a ton of money each month and fixed it. Apparently, our heat pump had never been programmed to work which was installed by another company.
