Can a heat pump replace my furnace and AC?

Yes. A heat pump provides both heating and cooling, replacing the need for a separate furnace and air conditioner. Many East Cobb homeowners choose heat pumps for the simplicity and efficiency of an all-in-one system.

Do heat pumps work when it gets really cold?

Modern heat pumps perform well in cold weather. In East Cobb, where very cold days are relatively rare, a heat pump handles the heating load efficiently most of the winter. Backup heat kicks in on the coldest nights.

Why is my heat pump blowing lukewarm air?

Heat pumps produce air that's warm but not as hot as a gas furnace — that's normal. If the air feels truly cold, there may be a refrigerant issue, a stuck reversing valve, or a defrost problem. A technician can diagnose it.

How long do heat pumps last?

With regular maintenance, a heat pump serves an East Cobb home well for many years. Because they run year-round, annual maintenance is especially important to keep them performing efficiently.

Is a heat pump more efficient than a furnace?

In East Cobb's climate, yes — for most of the heating season. Heat pumps move heat rather than generating it by burning fuel, which makes them very efficient in moderate temperatures. Gas furnace backup helps on the coldest days.

Heat Pump Service in East Cobb, GA

Always On Time

One Hour Heating & Air Conditioning® of North Atlanta

Heat pump service in East Cobb covers installation, repair, and maintenance for the heating and cooling systems that are perfectly suited to Georgia's climate. A heat pump provides both cooling in summer and heating in winter from a single piece of equipment — making it one of the most efficient options for East Cobb homes.

Why Heat Pumps Are a Smart Choice for East Cobb

Georgia's climate is ideal for heat pumps because they operate most efficiently in moderate temperatures — and East Cobb gets moderate temperatures for most of the year. In summer, the heat pump moves heat from inside your home to the outside, working exactly like an air conditioner. In winter, it reverses and pulls heat from the outdoor air into your home. Because East Cobb's winters are mild compared to northern states, the heat pump handles the heating load efficiently for the vast majority of the season. On the rare very cold night, a backup heat source supplements the system.

Heat Pump Repair for East Cobb Homes

Heat pumps have components that standard AC-only systems don't, including a reversing valve and a defrost cycle. Problems can show up as no cooling in summer, no heating in winter, ice on the outdoor unit, or a system that runs nonstop without reaching temperature. A technician trained in heat pump service understands how these systems operate in both heating and cooling modes and can diagnose issues quickly. Common repairs include refrigerant recharge, reversing valve replacement, defrost board repair, and fan motor replacement.

Heat Pump Installation and Replacement

If your East Cobb home's heat pump is aging or underperforming, a modern replacement delivers dramatically better efficiency and comfort. Today's heat pumps perform better in colder temperatures than older models and use less energy in both heating and cooling modes. Installation includes proper sizing for your home, connecting indoor and outdoor units, and testing the system in both modes. For East Cobb homeowners currently using separate AC and furnace systems, switching to a heat pump simplifies the equipment and can reduce year-round energy costs.

About East Cobb

East Cobb's moderate four-season climate makes heat pumps a natural fit. The community sees long, hot summers where efficient cooling is essential and mild winters where a heat pump handles heating with ease. Many East Cobb homes — from the neighborhoods along Paper Mill Road to the subdivisions near Sprayberry and Wheeler high schools — were built with heat pumps or have been converted to them during equipment upgrades. The technology matches the climate well.

Mathew the Operations Manager and Matt the Technician were a dynamic team. They provided a phenomenal level of service. They were professional and performed the maintenance and repairs fast.

We were very impressed with the professionalism of this new company. They not only were able to identify the problem with our air conditioner right away, but solved it in the most efficient and seamless way. We had been dealing with the draining problem of our unit for a long time and been frustrated with expensive work that did not solve the problem. Dealing with the One Hour company was a breath of fresh air and we do not hesitate to highly recommend it.

I got seasonal maintenance on my air-conditioning system. Scott did a great job of checking all of the filters and cleaning the outside condenser with a hose. He was very polite, very neat and very efficient and informative!

Update: After posting my original review, the owner Alex reached out personally and issued a refund that accounted for the high pricing and inconvenience of the experience, without being pressed for that amount. He also shared that he is actively working with the national franchise pricing model to bring rates in line with the local Seattle market. I appreciate the owner's customer service and professionalism. Original experience: The technician was professional and correctly diagnosed a failed contactor in my outdoor unit that was triggering a Nest thermostat error. The repair took two days due to a parts miscommunication, and the job was billed as a single flat-rate line item of $493 with no parts/labor breakdown, significantly above what an independent HVAC company would typically charge for the same repair. Bottom line: the initial experience had real rough edges, but Alex handled the follow-up with honesty and professionalism. Given the experience as a whole, I'd work with One Hour again.

This is the best company out there!! I called a few other companies who came to my home - over quoted me and I felt defeated! I reached out to One Hour Heating and Air— they came within 1 hour! And the problem was fixed in less than 45 min! No large bill! No taking advantage of me! And the best is— my heat blows stronger than ever! I bought my home in 2023 and had no idea it was not working properly until I started receiving $300+ monthly gas bills!! That stops today!! Thank you for saving me money on my Monthly bill moving forward. I needed this blessing ❤️ Service Man was professional as well. Highly recommend.

We had central AC added to our home 5 years ago. We decided to get an AC and furnace tune up before the summer. Matt, the technician from One Hour Heating and Air, was on time and polite. He pointed out that our furnace filter had not been changed since 2022. Big oversight by me. Matt explained how the air flows through the furnace and the direction the filter needs to be placed. I marked with a sharpie on the furnace an arrow so I would remember next time. Good piece of mind. Positive experience.
