Recommended Customer Reviews

I strongly suggest you avoid doing business with these folks. Paid over $6,000 for new A/C system. First we had a water leak from them not doing the plumbing correctly. Water came through our bedroom ceiling. Then we had no AC for several days - they discovered the person who installed the system also made a leak in the Freon line. Took a couple of days to come out and fix. Now we have moisture and sweating on unit and the city inspector failed the job. One nightmare after another - they must have grown too much and have reduced the skill level of installers.

After deciding that it was time to replace two 17 year old HVAC we called Casteel for a quote. We called them first because we have been very satisfied with their service over the years. The design consultant, Joe, spent time answering my questions and letting me tell them what I wanted in a new system. He did thorough testing of both systems . Since we plan to stay in this home we wanted an energy efficient, quiet system, that heated and cooled well. Our original systems were builder grade and very noisy. Joe recommended some additional duct work to improve air flow. I will say that I was shocked at the $$ for one 3 ton system and one 4 ton system (both 2 stage systems ). (Casteel installs lennox systems which have good rating ). I did get another quote for a similar system (Trane) and it was almost the exact same price! We decided to use Casteel because of our long term relationship with them and because of the warranties offered. Install crew was efficient and all of the work area was clean and neat. Bottom line.... I love my new HVACs . If I knew what a difference they would make I would have done this sooner! City official that came for inspection reported that Casteel always does a good job.

I heard about Casteel Heating on the Fish radio station. So, I decided to call to schedule an appointment for the AC tune-up special they were offering. From the first phone call to the completion of service, I received Excellent service. The rep I spoke with was so polite and efficient. They told me when the service tech would be there and he called before he got to my home to let me know how far away he was. He came in the time frame indicated and when he entered my home, he immediately put plastic protectors over his shoes. I was impressed. He serviced my AC unit and gave me a recommendation of additional work. All in all, it was a fantastic experience. You will receive excellent customer service, personable and knowledgeable service at a great price.

My husband and I have been customers of Casteel since the late 90s. At that time we lived in the same sub-division as Bob Casteel. Our hearts were very faithful customers. Over those years we purchased two air conditioning units, a tankless water heater and a furnace from them. We also paid for yearly maintenance. They used to call like clock work, but now we are paying for maintenance but have to beg for the company to come out. A week ago our air conditioner went out (we purchased it from Casteel in 2007). We used to be called 'premium' customers, but it took a full 24 hours for them to come out. The service people who show are always very polite. He told us we needed a new unit. Casteel company then said they could send someone out in another 24 hours to give us a quote on a new unit. Our new company replaced the unit within 24 hours. Just a note: Bob Casteel no longer owns 'Casteel' if you want to have a company take really good care of you, don't listen to the commercial, Casteel is now a TERRIBLE company.

I was having a closing on a house that when I donated a refrigerator that it was leaking from the ice maker line. Casteel came out and within 15 minutes placed a washer on the line which corrected the issue. He then went on to charge me $200; when I said that I believed that to be a high price he stated he could charge me more. I later protested the charge and they refunded me $50. I believe that repair should have been covered in the trip charge.

We used them for our HVAC and were very happy. However, we had them out for an estimate on some plumbing work and they quoted us over 9k. We had one of their leading, reputable competitors come out for a second opinion and the quote was $4,500. That is an outrageous difference!

I received a letter yesterday from Casteel advertising an AC pre-season tuneup for $49. I contacted them the next day to schedule appointment and was informed that because of the popularity of deal, they were now scheduling for end of July to first of August. It is May now. I told them to forget scheduling as that would be end of season, not pre-season. Stop sending letters for pre-season tune ups and not be able to do until end of season.

Very Disappointed and not impressed with Casteel Heating and air, after being a customer of Knight Heating and Air for over 20 years for my home,. I have used Knight for my business, my home and Knight serviced many of employees as well as my family.When Casteel bought Knight I recently had my first experience with a Casteel service tech. I thought he took a hucksters, approach trying to sell unnecessary service and unnecessary repairs. When I called to complain, I was told he was a supervisor, when I asked to please have his supervisor call me I would like to discuss..it has been over 3 weeks and NO PHONE CALL. After 2 decades of incredible service and no complaints where Knight was my go to for preventive service , repairs and purchase place for new equipment I am sad to say I can't support Casteel. I am involved in Snellville and alway felt comfortable reccomending Knight I can not support Casteel!!! VERY DISAPPOINTED [email protected]

At first I felt very pleased with Bill the sales man about all that was going to be done. However I felt rushed into purchashing from Casteel withan 18 month no interest guarantee. It turns out I now have a new credit card and cannot pay it with my existing credit card which was my full intention. Also we were told we would get a rebate from the gas company for installing the new furnace and air conditioner. however we were not given instructions on how the get the rebate. I did not have good feelings from the answering service when I really felt like someone should have answered the phone in person and really did take amazing care of me. I have not had that feel at all. Now I'm wishing I had gone with another company.

Watch out for these people. All that glitters is not gold. The quotes given to me were outrageous but I luckily got two other quotes and saved $2100. Do not take their word at face value!!! Beware
