If only I could give zero stars. For as long as this business has be in operations, I expected…read morethese guys to be pros. They lack professionalism and basic customer service expectations. I had a new AC and Gas furnace replaced last year, spending around $10,000. The new unit leaked a lot of water inside the house, on top the unit itself. I called and they came to "fix" the isssue free of charge. By fix I mean piling on more sealant than needed. It looked ridiculous. I noticed it leaking again, but when I called the second time I was told I would be charged. I was confused and a little upset at this point. I explained that I felt this shouldn't be an issue with such a new unit, and I feel a service charge of $89 plus repair cost was not right. The owner took the phone off the receptionist and said we will not be sending anyone to your home because we are afraid you won't pay and we will have to call the police. I was so offended. I couldn't believe what I was hearing. I fixed the leak myself. The guys who orginally put the sealant on, put it on outside of the pipe, when it should have been but on the inside as well. Easy fix! I guess they got what they wanted out me already. My money. However, they will not get any more business or referrals from me. My last word of advice: CALL SOMEONE ELSE!

April 1, 2026, I requested service for our upstairs Heat/A/C unit which would not turn on. This…read moreunit was purchased from Robertson's Electric 8 months ago. I called and An appointment was scheduled, promptly, for the next day. Our service technician was Leo, who was very courteous and knowledgeable. He performed a diagnostic check on the unit and after a short period of time, had it performing perfectly again. He took photos to show the problem to be a loose connection, most likely from the manufacturer. The upstairs is now cool again. I really appreciated Leo's kindness and explanation of the problem! I am grateful for his expertise and will recommend Robertson's and Leo to anyone needing expert service for their heating and A/C needs!

Ends up they come out again for no charge. A different tech came and told me that wire did need to be connected and when he did all was well. He told me the connection was very loose so he had to recrimp wire to make tight then left saying sorry this happened. As I said b4 when I connected wire it was very tight fitting. I believe 1st tech left wire barely connected so eventually it would come loose as it did Problem is if I did not catch this problem I could of been charged for a communication circuit board which would have been very expensive. The first tech knew that the wire had to be very tight to work properly and did not do so. So an unsuspecting customer could potentially have had to pay an expensive repair charge. Beware

Just had one of the heating and air guys out to our house to take a look at our unit. Not only was…read morehe able to arrive early, but was very pleasant and worked quickly to establish what was wrong with our indoor unit. He was able to get our heat going in the meantime, while waiting on a quote for a replacement panel by tomorrow. He was knowledgable about what size system we should have for our house and able to offer more quotes if we wished to replace the unit entirely because of the many problems we had before and the fact that it was small for the size of our home. Would highly recommend this company!

We've been a customer of AHA for about 8 years now and recently we decided to go with them to…read morereplace our entire HVAC. We had several quotes and ultimately decided to go with AHA because they contract with Trane. My experience with their service has never been an issue. All of their technicians are fine. We had one instance where our motor went out during last years ice storm and had to go with another company who could use their own personal 4 wheel drives to get it us to replace the motor. My experience with getting the quote from Dan was great. He is very knowledgeable and approaches quotes in a very helpful and common sense manner. I valued his input and how thorough he was. My experience with the technicians who installed our HVAC was great. They were wonderful to have in our home and we enjoyed interacting with them. My one and only issue with AHA is with their accounting person, Sharon Jenkins. About a week after the HVAC was installed I received an email from Sharon asking for more money for the install. I explained to her that the quote was $x and the final bill came out to be LESS THAN THE QUOTE. I even supplied the final invoice that I paid in full showing the difference thinking "oh she just needs to update her side to reflect the final amount". This is not uncommon and actually speaks volumes of Dan to over quote by just a little and have the customer a bit happier. After explaining the nuances of her job to her she was outright rude and refused to understand HER job. She incorrectly tried to say that the quote is the contract amount but didn't acknowledge the final invoice. Unwilling to go back and forth I contacted their customer service and was immediately told I was correct and my account was zeroed out. My advice to AHA is to part ways with Sharon. After reading a lot of reviews and speaking with people in my neighborhood it is a common theme that their only issue with AHA is having to interact with her. One person in fact said they went with another company solely because they refuse to ever speak to Sharon again. I would also suggest that AHA do a full investigation into her previous interactions with other customers. Were there customers in the past that didn't know any different and she was able to get that extra $$? Is this a systemic problem? Are their books in order? Where is this extra money going? As a customer it is not my responsibility to explain basic accounting to the accountant. I see her behavior as a giant red flag for any business. This review would be 5 stars if AHA had a different accountant who was actually kind and knew how to do her job.
