Do smart thermostats really save money?

Yes — smart thermostats reduce energy use by automatically adjusting when you're away, asleep, or the house is empty. Over Alpharetta's long cooling season, those automatic adjustments add up. Most homeowners notice a difference on their energy bills within the first few months of use.

What thermostat works with my HVAC system?

That depends on what type of system you have. Single-stage systems are compatible with almost any smart thermostat. Heat pumps and dual-fuel setups need models with specific control capabilities. Your technician can check your system and wiring and recommend the best match.

Can I install a smart thermostat myself?

On a basic single-stage system with modern wiring, many homeowners can handle the swap. But if you have a heat pump, dual-fuel system, or older wiring, professional installation avoids the risk of damaging your equipment or setting it up incorrectly. The technician also configures advanced features you might not set up on your own.

Does my older home have the right wiring?

Some older Alpharetta homes have thermostat wiring that doesn't include the power connection newer smart thermostats need. A technician can inspect your existing wiring and let you know if an upgrade or adapter is required. There are usually straightforward solutions that don't require running all-new wiring.

What is a dual-fuel thermostat?

A dual-fuel thermostat controls both a heat pump and a gas furnace in the same system. It automatically switches between the two based on outdoor temperature — running the more efficient heat pump during mild Alpharetta weather and switching to the gas furnace during the coldest nights. Proper configuration is key to getting the most out of this setup.

Thermostat Installation and Upgrade in Alpharetta, GA

One Hour Heating & Air Conditioning® of North Atlanta

Thermostat installation in Alpharetta upgrades your home's climate control with technology that learns your schedule, adjusts automatically, and lets you manage everything from your phone. For a city full of tech professionals, a smarter thermostat just makes sense.

Why Upgrade to a Smart Thermostat

A smart thermostat in your Alpharetta home does more than let you change the temperature from your phone — though that's a popular feature for commuters heading home on the GA 400. These thermostats learn your routine and adjust automatically, so you're not heating or cooling an empty house. They track your energy usage and show you where you can save. Geofencing uses your phone's location to detect when you leave or approach home and adjusts the temperature accordingly. During Alpharetta's long cooling season, even a small automatic adjustment when no one is home adds up to real savings on your electric bill over the summer months.

Making Sure Your Thermostat Works with Your System

Not all thermostats work with all HVAC systems, so compatibility matters. If you have a simple single-stage AC and furnace, most smart thermostats will work fine. Heat pump systems, dual-fuel setups, and multi-stage equipment need thermostats with the right control capabilities to manage the extra features. Older Alpharetta homes from the 1970s and 1980s sometimes have outdated wiring at the thermostat that lacks the power connection newer models require. A technician can check your wiring and system type, recommend compatible options, and handle the installation so everything communicates correctly from the start.

Professional Installation vs. DIY

Basic thermostat swaps on simple systems can be a DIY project, but for heat pumps, dual-fuel systems, zoned setups, and homes with older wiring, professional installation is the safer choice. Incorrect wiring can damage your HVAC equipment or cause the system to run improperly — heating when it should be cooling, or running the backup heat when the heat pump should be handling the load. A professional installation ensures the thermostat is wired correctly, configured for your specific equipment, and programmed to take full advantage of features like staging, scheduling, and automatic changeover between heating and cooling.

Tim was courteous and professional.

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.
