"Called on a Sunday morning when my AC went out. Mitch arrived within an hour, as promised, and had the air running promptly!"

"Fixed within a half an hour"

"These guys are super clean, kind, and professional! Air quality is much better now."

"Technician was A1 in tuning up and checking my system and answered all my questions. He checked my air conditioning, changed the filter in furnace and cleaned AC !! Get the pre summer special at $69. Well worth it."

"My first time getting vents cleaned in a nearly 50-year-old house. Working with Irish Mist (love the name!) was easy, pleasant, affordable, and quick. Arrived on time, got to work, cleaned the ducts - which had more than just dust in them, as some things rattled through the hose on the way out. Very satisfied customer. One thing I forgot to ask is before & after photos... might have been good to get, I wish they had done that."

"Our a/c went out in the dead heat and Zach came out and fixed it the same day! He was very knowledgeable and professional."
