How long does AC installation take?

Typical Peachtree Corners installations require 4-8 hours depending on system complexity and home size. Dual-zone systems or significant ductwork modifications take longer. Professional crews work efficiently while maintaining quality. Same-day installation often possible for straightforward replacements.

What's the cost difference between repair and replacement?

Repair costs range $150-$600 for most issues. Replacement costs $3,500-$7,000+ depending on system type and home size. Technicians help evaluate repair versus replacement economics. New systems save money long-term through improved efficiency and eliminate frequent repair cycles.

Can new AC work with old ductwork?

Often yes, but ductwork must be sealed, insulated, and properly sized for new equipment. Leaky ducts waste cooling and reduce efficiency. Professional installation includes ductwork inspection and necessary repairs. Older Peachtree Corners homes sometimes need duct improvements for optimal performance.

Do new AC systems include warranties?

Yes. Most manufacturers provide 5-10 year coverage on parts and 10 year coverage on compressors. Installation warranties typically cover labor for 1-5 years. Professional installation preserves warranty validity. Ask about extended warranty options.

What type of AC system works best in Peachtree Corners?

Standard split systems suit most homes. Ductless mini-splits work well for room additions or older homes without ducts. Heat pump systems provide heating and cooling efficiency. Local climate, home layout, and existing ductwork determine best choice. Professional consultation identifies optimal equipment for your situation.

Always On Time

One Hour Heating & Air Conditioning® of North Atlanta

Aging air conditioning systems fail when Peachtree Corners heat peaks, leaving residents without cooling. Modern AC units offer improved efficiency and quieter operation. Professional installation ensures proper sizing, airflow balance, and system reliability for 1970s subdivisions, newer infill developments, and everything between.

When to Replace Your AC System

Systems over 12-15 years old frequently require replacement rather than continued repair. Frequent breakdowns, rising energy costs, inconsistent room temperatures, and refrigerant recharges signal end-of-life issues. Peachtree Corners' humid climate accelerates wear. Rust on outdoor units, indoor coil freeze-ups, and compressor failures indicate replacement time. New systems provide quiet operation, better humidity control, and compatibility with smart thermostats. Professional assessment determines whether repair or replacement makes financial sense.

Proper Sizing and Selection

Incorrect AC sizing creates problems: oversized units cycle rapidly, wasting energy and leaving humidity uncontrolled; undersized units run constantly without reaching target temperatures. Peachtree Corners homes vary from compact 1970s ranch houses to larger modern estates, each requiring different cooling capacity. Professional technicians evaluate room size, insulation, window count, and local climate. They recommend equipment matched to specific home layouts. Proper sizing delivers comfort, efficiency, and reliability across Peachtree Corners' diverse residential stock.

What to Expect During AC Installation

Installation begins with outdoor unit placement in accessible, well-ventilated locations. Indoor components mount securely with proper condensate drainage. Ductwork connections ensure balanced airflow throughout the home. Refrigerant lines connect with precise measurements and pressure testing. Thermostat installation includes programming for comfort and efficiency. Electrical work follows safety codes. System startup includes performance verification and user training. Installation takes 4-8 hours for typical Peachtree Corners homes. Technicians test all functions before departure and explain maintenance needs.

Zo was fantastic! He came to my home to diagnose an issue with my AC and immediately impressed me with his knowledge, professionalism and decades of experience. He arrived prepared with the right tools, took the time to explain what was happening and helped me understand the different options available. Most importantly, he genuinely cared about finding the right solution for both my needs and my budget rather than simply pushing the most expensive option. I really appreciated his honesty, expertise and willingness to help and I would highly recommend Zo from One Hour Heating & Cooling to anyone in need of HVAC service!

Gage did an amazing job with repairing my HVAC unit. He had the part I needed a day before he came out to my home. He explained everything he was doing and answered all of my questions. I needed a blower motor. He completed the job in about 45 minutes. Gage arrived when he said he would. I will most definitely be calling One hour heating and AC again. Reasonable pricing and awesome customer service. Thanks again Guys

Chris Walker and his assistant installed a new mini-split at our home. They arrived promptly considering their long drive from Myrtle Beach. They performed thoroughly and professionally and were careful to keep us informed and involved in the process. The new unit seems to work perfectly. They also took time to show us how to clean filters and noticed that the ceiling fan needed to be redirected and also did that for us. In short, a very impressive perfomance.

Great service by One Hour Heating and Air Conditioning. Very detailed oriented. The technician Brayden did an excellent job. Cleaned and serviced the unit outside, even removed some weeds around the unit. Replaced a part under warranty. Would highly recommend, will request Brayden again for any future scheduled maintenance jobs.

My experience with One Hour Heating and Air Conditioning was great. Our A/C went out when the temperature was forecast to be 100 degrees. Cameron was very polite and knowledgeable and walked me through everything he was doing to diagnose the issue. I was prepared to hear that we needed a whole new system and after about an hour, he determined it was the blower fan in the furnace, The cost to replace the motor was 1/4 the cost of a new A/C unit. Further, he called the distributor and luckily they had a new one in stock. He drove to the warehouse to pick it up and installed it in about an hour. I would highly recommend!

The technician, Garrett, showed up to my house on schedule. He was very polite, listened to find out what our issues were with the unit, and then explained the work that he was doing. Afterward, he followed up with us to make sure that we understood everything that was done and to show us that everything is working properly. Before he left, he also made sure that our next service appointment was scheduled in the system. Great job all the way around!

Joshua was pleasant, respectful, knowledgeable, and conveyed all the details to me with pictures. Love his professionalism. Thank you for such a great customer service experience. As far as the price…I’m not sure it was a bit pricey to me but I never had the type of service performed on my unit before. I’ll have to ask around on that part but the customer service and work was great…thanks again.
