Do Heat Pumps Work Well In Georgia Humidity?

Yes, modern variable-speed heat pumps work well in Georgia humidity. That's because they run at lower capacities for a longer time. Some units have dehumidification modes that focus on moisture removal when humidity is high. The most important factor is to install the correct size.

What Refrigerant Do New Heat Pumps Use In 2026?

New heat pump installations use A2L refrigerants including R-454B and R-32. These mildly flammable refrigerants have lower global warming potential and comply with current EPA regulations.

Can I Replace A Gas Furnace With A Heat Pump?

Absolutely. Electric HVAC conversions replace gas furnaces with efficient heat pumps. This reduces energy costs and eliminates fossil fuel consumption. Keep in mind that these conversions may require electrical panel upgrades.

What Is A Manual J Load Calculation?

Manual J load calculation is a process that determines your home's heating and cooling requirements for proper heat pump sizing. Technicians have to go room-by-room to consider insulation, windows, house orientation, occupancy, and local climate data.

Will I Need An Electrical Panel Upgrade?

You will need an electrical panel upgrade if your current panel cannot support the added heat pump. However, we will provide a quote upfront and may offer you financing options.

How Long Does Heat Pump Installation Take?

Most residential heat pump installations are complete within 2-3 days. It depends on the complexity, required electrical upgrades, and ductwork modifications required. We will give you a timeline upfront.

Are Ductless Mini-Splits Good For Alpharetta Homes?

Yes, ductless mini-splits are good for Alpharetta homes. They're more commonly installed in homes without existing ductwork or room additions.

What Efficiency Ratings Should I Look For?

Look for SEER2 ratings of 16 or higher and HSPF2 ratings of 9 or higher for good efficiency performance. Premium systems achieve SEER2 18-20 and HSPF2 10+. Rebate and tax credit programs require minimum efficiency thresholds exceeding federal standards. Higher ratings deliver better savings but cost more upfront.

Do Cold-Climate Heat Pumps Work In Georgia?

Yes, cold-climate heat pumps work in Georgia. However, standard heat pumps also work well even for Alpharetta winters.

Can Heat Pumps Provide Hot Water Too?

Yes, heat pumps can provide hot water if you set up special heat pump water heaters.

How Do Hybrid Dual-Fuel Systems Work?

Hybrid dual-fuel systems combine heat pumps with gas furnaces. Then, they use automatic transfer switches to select a heat source based on outdoor temperature and energy costs.

Residential Heat Pump Installation Services

Our heat pump installation services include J load calculations for determining how much heating and cooling your house needs, plus ductless and hybrid heat pump systems.

Central Heat Pump Installation And Replacement

Central heat pump installation involves setting up the outdoor condensing unit, indoor air handler, and refrigerant lineset. We evaluate existing electrical systems, and integrate your thermostat to deliver heating and cooling through the whole house. In replacements, we upgrade aging furnaces to central heat pump systems.

Our technicians work with several inverter heat pump brands including Trane XV20i, Carrier Infinity with Greenspeed, Lennox, and Rheem. You can trust that we will install a heat pump system that can work effectively during Georgia's occasional freezes.

Ductless And Mini-Split Heat Pump Installation

Ductless heat pump installation is often for homes without existing ductwork or extra space. The ductless systems involve outdoor condensing units connected to indoor wall-mounted or ceiling-recessed air handlers.

These systems are perfect for Alpharetta townhomes near Avalon District and Halcyon where the lack of extra space makes it difficult to have ducted systems.

We install single-zone ductless systems within 24 hours.

Hybrid Dual-Fuel Heat Pump Setups

Hybrid dual-fuel systems combine heat pumps with gas furnaces. They come with transfer switches that automatically select a heat source based on outdoor temperature and energy cost. This way, your home uses energy efficiently while having a backup gas furnace in case of extreme cold.

Dual-fuel installations are perfect in large estates in Crabapple and Country Club of the South. The systems deliver heat assurance during extreme Georgia cold.

Our technicians will combine refrigeration and combustion systems. They'll pull in ventilation, gas connections, and electrical integrations.

Electric HVAC Conversions

Electric HVAC conversions replace gas furnaces with electric heating pump systems. To do that, we assess your electrical load, ductwork suitability, thermostat compatibility, and condensate drainage requirements. Some Alpharetta homes may need to upgrade their electrical panels to support heat pumps.

This service is perfect for homeowners who want to reduce gas service charges and their carbon footprint.

Reach out to us to handle your electrical panel upgrades and HVAC conversions.

Manual J Load Calculations For Proper Sizing

Before we install a heat pump, we have to calculate your home's electrical load. We use manual J load calculations to properly size the heat pump for your home. We go room-by-room to determine your home's insulation, windows, orientation, and occupancy to help us determine electrical load.

Oversized systems short cycle, causing poor humidity control and premature wear. Undersized systems struggle during temperature extremes to deliver the needed comfort.

We also need to document your home's electrical load according to Georgia's energy codes.

2026 Rebates On Heat Pump Installations For Alpharetta Homeowners

Alpharetta homeowners can save $3,000 to $10,000 or more on heat pump installations through combined federal, state, and utility incentives.

The federal Energy Efficient Home Improvement Credit provides up to $2,000 in tax credits for heat pumps that meet SEER2 and HSPF2 standards. Also, Georgia's Home Energy Rebate (HEAR) program offers rebates up to $8,000. The actual amount depends on the installation, household income, and efficiency levels.

Georgia Power's HEIP provides rebates up to $1,000 for heat pump installations that meet SEER2 and HSPF2. It's known to process faster than the other rebate programs.

Call (404) 689-4168 to ask about tax rebates on heat pump installations.

Modern Heat Pumps Vs. Traditional HVAC

Modern heat pumps are different from traditional HVAC systems because they constantly adjust their output to match your home's needs. They also use refrigerants that control humidity much better during Georgia's humid summers.

Variable-Speed Inverter Technology

Modern heat pumps come with speed compressors that adjust output between 25 and 100%. In contrast, traditional HVAC systems turn on and off.

The speed compressors improve the efficiency of modern heat pumps and allows them to run more quietly. They also make the heat pumps run a lot slower which removes more moisture during Georgia's humid summers.

SEER2 And HSPF2 Efficiency Standards

Many modern heat pumps meet SEER2 and HSPF2 efficiency standards. That means that they may cost more upfront, but they use less energy thereby reducing energy costs overall.

A2L Refrigerants (R-454B And R-32)

Unlike older HVAC systems, modern heat pumps use A2L refrigerants like R-454B and R-32, which replaced R-410A. Even though the new refrigerants are flammable and should be handled by technicians, they have less global warming potential.

Call (404) 689-4168 to book a consultation.

What Heat Pump Installation Costs In Alpharetta

Heat pump installation in Alpharetta typically costs $8,000 to $18,000 before rebates and tax credits. The final price depends on your home's size and electrical upgrades.

Higher-efficiency models (SEER2 18-20) cost more upfront than basic units (SEER2 14.3) but save money monthly on energy bills. Electrical panel upgrades also add $1,500 to 4,000, but may qualify for separate rebates.

Ducted systems cost differently than ductless options, and hybrid setups combining heat pumps with gas furnaces are the most expensive.

In total, federal tax credits and state rebates can reduce your net cost by $3,000 to 10,000. And, we offer financing options to our clients.

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!”
