Signs You Need a New AC Installation in Fort Smith

If your current system shows these signs, it may be time for a new AC installation from our Fort Smith experts.

System Over 15 Years Old

AC units over 15 years old lose efficiency significantly. A new installation can cut your cooling costs by 30-50% while providing better comfort throughout your Fort Smith home.

Frequent Costly Repairs

If you are spending more than $500 per year on AC repairs, investing in a new installation is often more cost-effective and provides reliable cooling for years to come.

Rising Energy Bills

Steadily increasing utility bills despite normal usage indicate your AC system is losing efficiency. New high-SEER units can dramatically reduce your monthly cooling costs.

Uneven Cooling Throughout Home

Hot spots and cold zones throughout your home suggest your current AC system can no longer adequately cool your space. A properly sized new installation solves this problem.

Using R-22 Refrigerant

R-22 (Freon) has been phased out and is extremely expensive. If your system uses R-22, upgrading to a new unit with R-410A refrigerant saves money long-term.
