“We had a great experience with this HVAC company. They were responsive, friendly, and able to schedule a technician for the same day we called, which we really appreciated. Our heater needed a pressure switch replaced, and they diagnosed the issue quickly and had it repaired within two days. The whole process was smooth, efficient, and stress-free. The technician was professional and knowledgeable, and everything is working perfectly now. We would definitely recommend them!”

“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!”
