First off, I got an appointment right away when I called! Zack P & William B came out to my house today to check on my unit, both of them were extremely knowledgeable & polite. I am no HVAC guru so they were sure to explain everything to me, and even showed me exactly which parts they were referring to. I did not feel pressured to purchase anything extra & the price was affordable! I am so thankful i decided to “Call Pernell” If you are in the market for an HVAC company or need them in a crunch- i highly recommend calling them!
