I have a service contract with Dalton Heating and Air, and for the last several years, I have had one issue or the other after they come out and do maintenance. Once, an aged wire disintegrated, it was not caught during a maintenance visit - I had to pay them to fix. Last year, within about 1 month of their maintenance service visit, the capacitor went out - - -( it was not caught during the service.) I had to pay them 195 dollars to come out and replace it. ( I checked the capacitors are $14.00 online.) I had a maintenance visit on 10/29/2025 - TODAY I woke up to no heat - so I reached out to another company because at this point I DO NOT TRUST Dalton Heating and Air - Come to find out that the Schrader valve has leaked out 8 pounds of refrigerant . . . $$$$$$$ to replace it! When I reached out to James W, (I have had several conversations with him, and he has ALWAYS been short and rude), he advised that it could have been caused by a technician putting gauges on and off the unit. Then he repeatedly asked me WHO I had working on my unit. . . . . For the service I have received from Dalton Heating and Air vs the constant paying more for this and this and this. (Because it has not been caught during maintenance THAT I PAY FOR) In my opinion They ARE NOT worth cost. read more

Let me say I am not easily impressed and I write this review after 2 installments and 3 months of dealing with this company. The FIRST HVAC contractor to do what they say and follow up on any issues in a timely manner (because nothing is perfect). Don't know about the rest, but I'm pleased read more

I am the Operations Manager for a company that covers 6 North Georgia Counties. Dalton Heating and Air handles many of our service needs as well as new installs. They treat us as if we are very important and get to our jobs a fast as possible. They have been able to solve issues that other companies could not diagnose. They are very reliable about resolving warranty issues and do not charge me for any part or issue covered by warranty. I highly recommend Dalton Heating and Air for any A/C related needs. read more

Shout out to my friends at Dalton Heating and Air. Our heater finally quit last night and while we had it set for 68 the temp was really 60 degrees when I left for work. I called them when I left and they're came out within 30 minutes to fix it! Normally it'd be fine but we have babies we have to keep warm. Thank you DH&A for the responsiveness! read more

I got a new Trane unit 2 years ago and they installed it same day which was good. But on the second year somehow my unit seems to consume freon being a brand new unit. So my wife called a few weeks ago to have a service man come out and check for leaks and the man told her there was not any leaks but had to put 2 lbs of freon in the the system hmmm! So it cooled again like it should but then all the sudden where did the $330.00 worth of freon go again after being told there aren't any leaks he could find. Not only that the first time we called they told us we would still have to pay and would cost such and such amount of money so we called a family known company local and he told us there was a leak and we would and should have dalton heating and air come out and should be covered under warranty needless to say we did and was charged 330.00 for a hot house again and pretty much the thousands of dollars we paid to them just went out the window because now the unit is no good for nothing well maybe a yard ortiment but that's not what I bought I am sure of at least not what I was told because the TRANE HAS FAILED THE ADVERTIZING YOU CANT STOP ONE IT KEEPS ON EATING FREON SOMEHOW AND NEEDS MORE AFTER A PROFESSIONAL COMPANY SAID THEY COULD NOT FIND ANYLEAKS IT IS JUST LIKE A TIRE ON A CAR IF IT GOES FLAT IT DONT ROLL ANY MORE SO THERE IS A LEAK ACCORDING TO THE COMMON SENSE THE GOOD LORD PROVIDED EACH AND EVERY MAN AND WOMEN WITH AN AC UNIT BEING BRAND NEW AND COSTING THOUSANDS OF DOLLARS TO INSTALL DONT CONTINUUSLY NEED FREON TO OPERATE ATLEAST FROM MY EXSPERIANCE IN THE INDUSTRIAL MECHANICAL FIELD AND FROM COMMEN SENSE PLEASE CORRECT ME IF WRONG BUT DOUBTFULL. I AM HEARTBROKEN THAT A KNOWN COMPANY COULD DO THIS TO A FAMILY BECAUSE 330.00 dollars is just not change to me I could of used it for other needs my family needs. Just had to vent a little read more
