Think twice. I used a mailer $39 coupon for an HVAC inspection and ended up being offered a $8-10K system replacement. They did correctly diagnose a line leak but offered no other solution than an entire replacement. Do not trust such advice, get a second opinion, or get taken to the cleaners. I used my previous HVAC company for the fix, not for a replacement that was not needed.

Talk about good service is one thing but add to it an education about a ""new to me system"" was an unexpected and appreciated side benefit. The tech was all about checking the system as requested but went further to communicate things an owner would not necessarily have known. That's HELPFUL service and with a smile no less!

I had scheduled Casteel to come do some simple electrical work to replace a cut wire. They gave me a 12 hour window to come so it which is flat out ridiculous. They told me they would show up between 8a-8p. I called at 8a to find out per them to get a more direct time frame. Almost 4 hours later they call me back to tell me that they don't know when they will get there. The dispatcher then tells me they tried to call at 11a to reschedule me which was a flat out lie. So if you want unreliable service and people to just lie to your face then this is the people to hire. Would rather risk electrocution then give these guys a cent.

Technician was great! I was able to receive an appointment the same day I called. Although I agreed on the estimate, I later found out that $250 for one ballast in one light was very pricey. I emailed and asked for a breakdown of the services. I was informed they couldn't do that. Odd! I was told that 60% was installation and 40% was labor? What about the parts? This experience would cause me not too user them again. Plus, the cost


Hi! As stated above, I agreed to the estimate. But...the invoice only said ballast $219, service $39...nothing else. After speaking to other electricians bc I had the work done (Casteel said it could have been an electrical emergency due to
smelling gas), I learned the quote was extremely pricey. This is when I asked for the breakdown which I did not receive. I also asked a question bc there is a delay. This question was not answered. I have the email if needed. Allison Wirth 30043

Very courteous plumber, I liked how they sent a text with a photo of him when he was on his way for an estimate. However, their quote came in WAY too high, 2.5x more than the quote I got from the company I ended up using, and Casteel wanted to use a flexible pipe ""for quicker installations, saving money based on time."" The company I ended up going with used black steel pipe (which should last longer), and still ended up being $800 (2.5x) cheaper. Also, they didn't charge me to try to earn my business the way Casteel charged me $39 just to give me an estimate. Save your money and look elsewhere.

I am extremely impressed with the Casteel team and I am equally impressed with Lennox. I've already seen a major decrease in my utility bills.

I recently purchased a ranch on a basement and from day one I knew the split HVAC system needed to be replaced. I work for a company that does large scale commercial HVAC and one thing I know is you can't cheat on the install. A good install and good equipment means longevity!!! With that being said most of the salesman from other companies wanted to use pre-existing stuff to cut cost. Also they advertised one brand but try to push a lesser brand at the same price. I'm sure you've all seen their flyers!

Seth was the salesman did a great job of going over every detail and answered all my questions.
Scott and Jose where the install team leaders, I felt extremely comfortable leaving my house and letting them do their job! Jeremiah return later to connect both of my units to the internet and setup my icomfort account. What more can I say!!!!!!!

I have been using Casteel, since we moved to Georgia in Sept. 2009. Everything they have done for us is quality work. I recently had, Elijah one of the great electricians with Casteel, replace my old landscape lights and he did a great job and I would invite him to my home anytime.
Thank you!

Casteel bought Knight Heating and Air, which I had used for years. I purchased a service agreement from Casteel for my home and rental property when my Knight agreement was up for renewal.

My rental property had a heating issue. Casteel charged $71 to assess the problem and quoted $1050 to repair. I had another authorized dealer to come out for a quote. The other company charged $35 to assess and a much less price to repair (around $600). Not sure what good the service agreement does when you have an issue. Once this service agreement expires I will not stay with Casteel. They are friendly but I felt I was being ripped off by them. I'm very sorry Knight sold to Casteel.

Prompt, but expensive!!!
I had a toilet back up on a Saturday morning and called Casteel. Very polite and efficient and was told that the basic charge for clearing the blockage with a ""snake"" was $39 plus additional charges for the equipment. Plumber arrived on Sunday morning, did a professional job and charged me $198 for the job ( it took about 15 minutes).

Not sure that I will go that route again any time soon.
