I contacted Carlton's Heating and Air after my AC unit went out on a 90 degree day, it was not a good situation to be in. All other companies told me a week out but I called them told them I work from home so my son and I are here most of the day and it would be hard to make it until next week. Crusie Parker understood my situation and moved some stuff around and came to fix it after 5pm that day! Couldn't be happier AC unit works now and now they do preventative Maintanence on my system so I'm sure I won't be in the same situation again!

No call, no show. I was attempting to be a return customer because our furnace is in need of repair. I called on Wednesday, January 12 and they offered me an appointment for 8am-12pm the next day, which I gladly accepted. The next morning I waited at home until 12pm. No one called or showed up, so I called their business and was told that my appointment was actually for 1pm-5pm. I knew this was not true, but figured it was a misguided attempt to cover for their team, so I accepted this, rearranged my other commitments for the day and waited an additional 5 hours.
To my disappointment, still no one showed up. I called them again at this time, and the person who answered took my information and said I would receive a call back. I did not. I would have understood if the business was booked and unavailable, especially in this cold weather, or if an unforeseen event had arisen with a team member and we had to reschedule. What I do not find acceptable is that (1) I wasted my entire day at home waiting, when I could have contacted another company (2) they had the audacity to lie about my appointment time and (3) they did not give me an explanation or even respond to me afterwards.

Our Gas pack was almost serviced Oct 18 and heat exchanger was defective. Today is Dec 1 and the wires are laying on the ground and screws all around. The exhaust deflector is also on the ground. Parts to repair the under warranty parts are either being delivered by the end of last week or still on permanent back order. I have yet to received any calls from them about any progress or any suggestion as to how to get heat restored.

Had the best experience yesterday with John. He was very friendly and knowledgeable on what the issue was. He wasn't in a rush to leave without resolving the issue. He was very professional and explained to our family what the issue was and we slept very good because he fixed the issue. Even speaking with the female over the phone scheduling our tech to come out was very friendly. This company clearly knows what their doing and you won't go wrong choosing Carlton heating & Air conditioning.

Carlton Heating and Air Conditioning responded quickly to my call and sent a technician out ASAP. John arrived promptly and was ready to work on our AC unit. I was surprised to hear he was the owner and responded to service calls. He was very knowledgeable, down to earth and made it clear that he was not trying to force us into replacing our unit as many other companies do. He got our old unit up and running in no time! We signed up for the Peak Performance Maintenance Agreement. They have a customer in us for life!

The crew was extremely polite and professional. They worked very hard, answered all my questions and were never rushed. I had a new AC unit installed, a new furnace and new duct work, all for thousands less than other companies would have charged. After the job was complete the owner, John showed up at my door to ensure everything was done professionally and to see if I had any questions or concerns. Was a great touch. This team made the process easy, fast and efficient.
