Fort Smith's heat puts heavy demand on AC units. Systems approaching this age have typically lost significant efficiency and become unreliable right when you need them most.

If you've had your technician out two or more times in the past year, those repair costs are adding up. A new system with a fresh warranty often makes more sense financially.
If your OG&E or AEP bills spike every summer despite normal usage, your aging AC is likely the culprit. New systems with higher SEER2 ratings use significantly less electricity.
Rooms that are always too hot or too cold often indicate an improperly sized system. A new correctly sized installation eliminates hot spots.
If your AC still runs on R-22 Freon, every service call for refrigerant gets more expensive since it's been phased out. Modern systems use R-454B refrigerant that is readily available and affordable.

⭐⭐⭐⭐⭐ The Best in Fort Smith! “We needed a full system replacement at our home in Chaffee Crossing, and Riverside Heating Air Plumbing was incredible.

The cost of AC installation in Fort Smith AR varies based on system size and SEER2 efficiency. Riverside provides transparent, upfront quotes that include all necessary City of Fort Smith building permits, ensuring your new unit meets local mechanical codes while maximizing your home’s energy savings.
In most Fort Smith homes, the furnace and AC share the same blower motor and ductwork. Matching a new high-efficiency Air Conditioning unit with an old, inefficient furnace can actually “choke” your airflow and void your new manufacturer warranty. Replacing both at once ensures the entire system is balanced, saves you on labor costs, and significantly lowers your monthly OG&E or AEP electric bills.
Most residential installations in the Fort Smith area are completed in a single day. Our crew typically arrives between 8:00 AM and 9:00 AM and has your home cooling again by late afternoon. If your project requires extensive ductwork repair or a complex attic installation, it may take a second day, but we always prioritize getting your “cool air” running as quickly as possible.
We install top-tier brands like American Standard, Ameristar, and Heil because they are engineered to handle the intense humidity of the Arkansas River Valley. Choosing these brands ensures that your Fort Smith HVAC system has local parts availability for faster service in the future.
Yes! We understand that a new HVAC system is a major investment. Riverside offers several flexible financing programs for Fort Smith residents, including low monthly payment plans and competitive interest rates. This allows you to upgrade to a high-efficiency system that pays for itself through lower utility bills without a massive upfront hit to your savings.
We generally suggest the “5,000 Rule” for Fort Smith homeowners: multiply the age of the unit by the cost of the repair. If the total exceeds $5,000, a replacement is usually the smarter investment. Additionally, if your system still uses the phased-out R-22 refrigerant, any repair involving a leak will be extremely expensive. A new installation provides a 10-year warranty and total peace of mind.
While our home base is located right here in Fort Smith, our fleet is fully equipped to provide #1 HVAC service to the entire River Valley region.
