What Is SEER2, And What Does It Mean For Homeowners?

SEER2 is a testing standard used to measure cooling efficiency under updated conditions. For homeowners, higher efficiency generally means smoother operation and more consistent comfort over time.

Can A New Heat Pump Help With Humidity?

Yes, a properly sized heat pump can help manage indoor humidity more effectively than an aging or oversized system. Consistent operation helps maintain balanced temperatures and a more comfortable indoor environment.

Signs You May Need Heat Pump Replacement

Signs you may need heat pump replacement include frequent repairs, constant runtime with poor comfort, rising energy bills, loud or short cycling, uneven room temperatures, and heavy reliance on backup heat.

If your heat pump shows one or more of the signs below, replacement may be the more reliable option compared to continuing repairs.

Repairs Keep Stacking Up

When a heat pump needs repairs again and again, it often means the system is wearing out overall. Ongoing breakdowns can turn into a cycle of service calls without long-term improvement. Replacement helps put an end to repeated disruptions and uncertainty.

System Runs Constantly But Still Feels Uncomfortable

A heat pump that runs nonstop but still leaves the home feeling warm, cold, or sticky is no longer performing efficiently. Over time, worn components can prevent the system from keeping conditions balanced. Replacing the unit can restore steady comfort instead of constant strain.

Energy Bills Keep Climbing

Sudden or steady increases in energy bills are a common sign of declining system performance. As parts wear down, the heat pump has to work harder to do the same job. Replacement can help reduce excessive runtime and bring energy use back under control.

Loud Cycling Or Short Cycling

Unusual noises or rapid on-and-off cycling often point to internal wear or system imbalance. These issues can cause added stress on the equipment and lead to further damage. A new system operates more smoothly and avoids unnecessary cycling.

Uneven Temperatures Throughout The Home

Hot and cold spots from room to room often signal that the system can no longer distribute heating and cooling evenly. Older heat pumps may struggle to keep up with changing demands. Replacement allows for more consistent comfort across living spaces.

Backup Heat Runs Too Often

If backup heat seems to run frequently, even during mild conditions, the heat pump may no longer be carrying its share of the load. This can lead to higher operating costs and reduced comfort. Replacing the system helps restore balanced operation without overreliance on backup heating.

Heat Pump Systems We Replace

We replace electric and ground-source (geothermal) heat pump systems for residential homes in the Alpharetta area. Each system type serves homes differently depending on layout, comfort needs, and existing infrastructure.

Below is a quick overview of the heat pump systems we commonly replace and service.

Electric Heat Pump Systems

Electric heat pumps are one of the most common residential heating and cooling systems. Over time, these systems can lose performance, struggle with comfort consistency, or require frequent repairs. Replacing an aging electric heat pump helps restore dependable heating and cooling throughout the home.

Ground-Source (Geothermal) Heat Pump Systems

Ground-source heat pumps use stable underground temperatures to support heating and cooling. Like any mechanical system, geothermal equipment can wear down over time. Replacement helps maintain dependable operation and supports long-term comfort when existing geothermal systems reach the end of their service life.

Why Correct Heat Pump Sizing Matters For Humidity

Correct heat pump sizing matters because it directly affects how well your home controls humidity and maintains steady comfort. In Alpharetta's climate, a system that is too large or too small can lead to sticky indoor air, uneven temperatures, and longer run times that never quite feel comfortable.

When a system isn't sized properly, comfort issues tend to show up quickly and continue no matter how often the system runs. Below are some of the most common problems caused by incorrect sizing.

Oversized systems cool too quickly and shut off before removing enough moisture from the air
Excess humidity can make rooms feel clammy even when temperatures seem correct
Undersized systems may run constantly without reaching comfortable conditions
Improper sizing can lead to inconsistent temperatures from room to room
Ongoing comfort problems often remain even after repairs

Heat Pump Replacement Cost In Alpharetta

The cost of heat pump replacement in Alpharetta depends on several factors, including system type, system size, installation complexity, existing home setup, and any updates needed to support the new equipment.

Every home and system is different, which is why replacement costs can vary. Below are the most common factors that influence the overall scope of a heat pump replacement.

System type: Central heat pump systems and ductless heat pump systems require different installation approaches, which can affect the overall project scope.

System size: Larger homes or homes with higher heating and cooling demands may require larger systems to maintain consistent comfort.

Existing system condition: The age and condition of the current heat pump and related components can influence how much work is needed during replacement.

Home layout and accessibility: Tight spaces, attic installations, or difficult outdoor unit locations can affect installation time and setup.

Electrical and infrastructure needs: Some homes may need updates to electrical connections or mounting areas to properly support a new heat pump system.

Ductwork condition: For central systems, existing ductwork may need adjustment or repair to ensure proper airflow and performance.

What To Expect On Replacement Day

Our heat pump replacement process starts with an in-home evaluation and planning. Next, we review system options, remove the existing equipment, install the new system, and complete testing before walking you through.

Below is a simple breakdown of what typically happens on replacement day.

In-Home Evaluation And Planning

We begin by reviewing your existing system, home layout, and comfort concerns to determine what type of replacement makes sense. This helps ensure the new heat pump is sized and planned around how your home actually uses heating and cooling.

System Options And Recommendations

Based on the evaluation, we review replacement options that align with your home and preferences. Our goal is to explain choices clearly so you understand what's being installed and why it fits your needs.

Removal Of The Existing System

Next, the old heat pump components are carefully disconnected and removed from the home. This step also allows the team to prepare the area for the new equipment.

Installation Of The New Heat Pump System

The new indoor and outdoor components are installed and connected according to the planned setup. This includes securing equipment, connecting electrical and airflow components, and making sure everything is positioned properly.

Testing, Setup, And Walkthrough

Once installation is complete, the system is turned on and checked to confirm it's operating as expected. Before leaving, we walk you through basic operation, filter care, and what to expect next.

“Most recent service. 2/10/26 Roy and the other technicians did an excellent job installing my new heating/ac system. Roy was patient answering my questions about what was going to happen. He is polite/ friendly and very knowledgeable. Roy worked well with the crew, they all had a specific job, and they communicated well to get things done. I am very pleased with the service, and my new heating system.”

“Pablo did an exceptional job with our new furnace installation. He was polite, informative, and thorough throughout the process. Everything was cleaned after the installation was finished as well. Northern One has a great feature where you get a text message when your tech is heading to your location, along with their picture and name so you know who is coming. They were also prompt in showing up and diagnosing the initial furnace issue and also with the installation of the new unit.”

“We have been customers of One Hour Air for years. The company has been through some changes. Despite those changes in ownership we have found that their technicians are consistently friendly, patient, knowledgeable, and do follow up. During our most recent visit we had to replace the unit. Sheldon was so helpful and patient as he explained the pros and cons of our options and they were here doing the work just a couple of days later. The team was efficient and cleaned up well after each day of work. On the last day, Andrew and Carlos completed checking the ductwork, replacing the vents, and installing the insulation we'd also requested. What impressed most is, although it was late in the day, they took the time to walk us through the system, answer our questions, and make some little adjustments here and there that we requested for presentation's sake. We appreciate Sheldon who took the time to follow up the next week to check the work, answer some more of our questions, and update us on the status of our air filters. As a whole, technicians communicate very well from their anticipated arrival time, to the actual work, then the debrief of what was done. We have found that they work to standard despite the time. For customers who are more computer savvy, they are increasing their use of electronic contracts to include a virtual notary, same-day approval for loans (with decent rates), and the permitting of the work. My only recommendation to the company is to keep in mind that not everyone is technologically savvy and it may be helpful to have administrative staff available to provide guidance. Also, keep in mind that in these times of e-mail and telephone scams it would be very helpful to know to expect e-mails and what to expect of the links. Overall, we have been customers of One-Hour Air for years and expect to continue with them. We really appreciate the team and feel so much better about the air quality in our home. :)”

“Called a few months ago and they sent a guy named travis.. I DO NOT RECOMMEND Travis.. all he will do is Bang and hit your furnace then proceed to tell you oh well you're going to need a whole new furnace. While he's being rude as can be for no reason. Will compare his living to your living.. but he put a part on it made it work for the time being didn't put none of the panels back on or anything.. few months go by and the furnace is now blowing cold air. So we gave them another chance. They just sent a guy named Cory over and it took him 5 minutes to figure out was wrong . Ordered the part the next day and a guy named marquis came and put it on cleaned up everything . I just wanted to thank them for helping me out when Travis tried to make a dollar out of me. If they try to send you a guy named Travis just send him back where he came from.. I recommend Cory . Thank you sir”

“Joshua is a great man! He came to my house when he said he would and diagnosed and repaired my system. He didn't try and just sell me on getting a new system. He educated me on what my system is and advised me on what I'd be looking for in the future if I decided on a new system. I really appreciate that he took his time and made sure that my heat was working with the on coming cold front we got rolling in. I feel blessed to have met him, he is a great man! One Hour Heating and A/C have a huge asset in him and they will be the only company I contact for any HVAC concerns in the future. Do not hesitate to call on this company for any of your HVAC needs. Thanks again Joshua!”
