Jeremy and his Helper did an amazing job installing my a/c unit inside and out. And Lisa stayed on top of the company as far as making sure they had all of the parts that was needed. Thank you Guys for all of your hard professional work.

This is a very good professional business for HVac. Prices were very reasonable. I requested a quote and they were the first to respond. Mrs. Lisa sent a tech out that very same day, and it was Seth. He was able to pin point the problem and let me know what was going on. They ordered my parts. I was even able to track my technician from start to finish. Thank you Mrs. Lisa and Seth. I would definitely recommend them.

We are very pleased with William Precision Air Services. They came out Saturday and diagnosed our issues. We had other techs come out from other A/C companies that would not take the time and find the real issue over a 5 year period... Yes, I said 5 years same on going issues. Very costly... Our unit was just put in 6 years ago and had a coil issues and had rusted our unit due to a leak that was never found by other techs because they didn't do their job correctly. If they would of done their job correctly, we wouldn't had to spend $1600 to replace the unit. William Precision tech found the issue within no time. He explained what happened and how it could be fixed. He took his job very seriously and did it right. If you want the job done right, call William Precision they will get the job done. Thank you William Precision!! The Moore's
