“Problems with heating zone controller. Tim diagnosed the issue, updated the firnware for the circuit board, and tested the system. Excellent work! We also had him replace a thermostat.”

“AAA Northgate Heating & Air Conditioning gave us prompt careful, professional service that got our old much-loved Singer furnace running after finding an electrical problem with our old flue damper. The furnace runs great. The technicians were very courteous, helpful and gave us valuable advice. We appreciate it and signed up for a service contract.”

“We called Casteel to help us figure out what was wrong with our basement heating unit. We knew upfront that the cost was $90 for someone to come out. We were then told it would be another $285 for the technician to do a leak test even though we told him where the leak was. We agreed to both of these costs. He said Casteel "was not in the business of repairing coils" but they would give us a quote if we wanted one. He then told us the cost to repair the coils would be approximately $6500 (even though the coil was still covered by Trane's warranty) or we could replace the unit for approximately $15,000. Mind you, we have lived in this new construction, custom built home for 5 years. When I asked about this unit being so new, he told me "It's mechanical and mechanical things break." We were put off by the astronomical quote, the attitude and the feeling that we were getting scammed to some degree. We took the quotes and told him we were going to check with other companies. We got a referral to a smaller company, Henson Mechanical out of Monroe, Ga. They are a smaller, family owned business. We explained what we learned from Casteel, but we did not tell them what they wanted to charge us. Henson did not charge us to come out to our home, they did not run another test, and they were very responsive to our questions. The owner of Henson came out himself (arrived around 8:15 in the morning) and said he didn't need to run a test; he said he could see where it was leaking without a test. He gave us a quote of $2700 to replace the coils. Since the unit was still under warranty, Mr. Henson went out to Duluth, picked up the warrantied part, and had his guys replace the coil all by 3:00 that afternoon. The two men from Henson that fixed our heater were professional, polite, and knew what they were doing. To say our experiences with the two companies are night and day would be an understatement. We literally spent less than half of the repair price given to us by Casteel for the same work. We even signed up for Henson's annual maintenance plan for $225 per year, and we still were less than half of Casteel's original quote. Please do not use Casteel. They are overpriced and put their financial gain before their customers. We will continue to use smaller, family owned businesses like Henson Mechanical whenever possible. We could not recommend Henson Mechanical more, and we are thankful for the referral to them. You get people who care with better customer service and cost. Thankful we were smart enough to get a second opinion!”

“The maintenance program is very good and Raphael was very good at helping me understand the conditions and needs of my system. He is both knowledgeable and professional. Florida has a unique environment on AC units and he was very helpful. UV light for mold mitigation. Thank all again.”

“Service is always outstanding with Mitchell's One Hour Heating and Air Conditioning. They are quick to get a technician out and make sure your needs are taken care of. Justus Papp was the latest technician to come out, and he was amazing. He took the time to clearly explain what was happening, what needed to be done, and made sure we were comfortable with the plan. He returned two days later to complete the job, and we couldn’t be happier with the results. I truly appreciate the hard work and genuine care that everyone at this company puts in. They also have the best associates answering the phones. Always puts a smile on my face Highly recommend!”

“Michael was great. He came out at the last minute to tune up our furnace and a/c unit. Our furnace is 15 years old and has a humidifier that's never worked well, if at all. He got it going w a simple adjustment. There's also a seperate filter for the humidifier part of the furnace. I didn’t know that. Apparently neither did the half dozen guys we've had over the years who came out and did a reported inspection and cleaning. Ive lived in my house for over 10 years so you can imagine how disgusting that filthy old filter was! We've even supposedly had the humidifier "worked on" a couple times. Michael spotted it right away. He was thorough and took his time, which we appreciated.”
