Casteel did a great job replacing our two air conditioning systems. Adam helped us pick the systems with the capabilities we wanted. He made it very clear what we were buying and what we were not buying. All Casteel employees on site for the installation were courteous and helpful. The quality of the work is outstanding! Hats off to Junior, Nick, Mohammad, and the others on the crew that day!!

I'm so grateful for the team at Casteel. I've never had a bad experience with their office folks or technicians. Cody came by yesterday and inspected my HVAC systems in my new home. There were several conditions that I would not expect a home inspector to find. Cody carefully went over each system, identified issues and sympathetically revealed the costs involved. Thank you Cody

Recently had casteel come out to fix an AC issue not cooling. They are Way Overpriced and I feel like not very honest. The first thing the tech told me was that first off you need a thermostat and its not covered under warranty. Reason stated it was not sending low voltage to outside unit. The price quoted for just the thermostat was 512, for a $150 part. Which means to install the faceplate, 2-3 wires to connect, it was going to cost $372 labor. Took him about 10 minutes to install so you can do the math on the labor rate. He tried to convince me the cost was high for a 3 yr warranty that they provide. BUT the part comes with a 5 year manufacturer warranty as long as professionally installed. Quality of work was good but way overpriced. Btw in the write up on my receipt, only the faulty transformer was listed as the issue, nothing about the thermostat. Hmmmm. I believe the transformer would be the part that would direct current to the outside unit. So not sure the thermostat was an issue at all

Update: invoice 1003677 Feb 20. Read back over description, does say faulty thermostat but was tested with faulty transformer. Thermostat was not retested after transformer was replaced

I had an excellent experience with John from Casteel who serviced my home on January 24, 2026. From the moment he arrived, his energy was professional, calm, and reassuring. He is a great listener and took the time to fully understand my concerns before explaining everything clearly and thoroughly.

John was extremely knowledgeable and transparent, walking me through what was happening, what needed immediate attention, and what could be addressed later—without any pressure. The pricing he offered felt absolutely fair for the scope and quality of work provided.

He completely fixed what had been a major issue: a large hole in the vent connected to the hot water heating system, which was also heavily rusted. His work was thorough and done with real care. I also appreciated his communication style—he speaks clearly, maintains eye contact, and makes sure you truly understand what’s being done and why.

Overall, John delivered outstanding service, and I would confidently recommend him to anyone looking for a skilled, honest, and professional technician.

We are beyond happy with the service we received from Casteel today. Our old water heater was on its last leg and needed to be replaced ASAP. Another company came out, charged an estimate fee, and scheduled an appointment, which they later cancelled and delayed. We called Casteel and they sent someone out the same day.

Jamie, the technician, was super friendly and knowledgeable. He replaced the water heater the same day for a cheaper price than we were quoted by the other company. He explained everything clearly and did excellent work. We couldn't have imagined a better technician and we highly recommend him. It's great to have peace of mind knowing our water heater isn't going to burst and flood our house tonight.

Great overall experience and would recommend Casteel and Jamie to anyone.
