What we know about homes in Williston
Half of Williston's homes are 40 years old or older
The typical home in the city was built in 1983, and about 1 in 10 is a manufactured home. Most are on a replacement AC by now, so the age of your system matters more than the age of the house, and a system from before 2010 may still run on R-22 refrigerant, which hasn't been made since 2020.

How much does AC repair cost in Williston?
It depends on the part and the system. The tech finds the problem first, then gives you a written price before any work starts, so you decide with the number in front of you.
When should I book a winter tune-up?
Before the season turns, so problems are found while the system is easy to fix. You pick the 2-hour window online and get a written report of what the tech found.
