We’ve been O’Callaghan customers for about 30 years. Same experience every time. Prompt. Reliable. High quality service. And that starts at the top from Dennis and Becky. None better. First and only number to call.
Always get great service with Carl. Getting ready to move and will call and get new contract. This will be the 4th house I’ve had O’Callaghan service!
Very professional and quick response . Their technician fixed our issue with our AC quickly.
Have used O’Callaghan for 20+ years and they have never disappointed me
The technician, Wally, was great. He was professional and efficient. He explained the situation and resolved it. I’m happy to be a Callahan customer!!!
Bobby came out to check out entire system and he did a super good job. Great folks to work with so far! Ask for Kelly she keeps it all in order
Arrived 10 min early. Very polite & professional. Explained work & discussed preventative maintainence. Great people!
Outstanding service. I received an honest quote from Jordan who was communicative and worked with me in order to get the best service for my home. The installation of our new unit was scheduled 4 days from the quote and 2 technicians showed up early. They were very polite and worked the entire duration they were at my home. They explained everything and were very knowledgeable. They provide a 1 year free service with their installation. I am very happy to have chosen their service.
I had 2 other companies come in to look at some of my units that weren't working. They both tried to sell me new units, but O'Callaghan fixed them both for under $300. Of course I signed up for their maintenance plan...I know I can trust them:)
They are my go-to for HVAC services not only for me but also who I exclusively recommend for my real estate clients. Hands down recommend!
Carl was absolutely fantastic. He was extremely knowledgeable and patient with me. He went above and beyond with his help and guidance.
Antonio was very professional, took the time to explain each step and process before actually doing the job. Very knowledgeable. Thank you!!!
Carl had serviced another unit in building for me When I moved and needed service for the unit I purchased there was only (1) guy to have service it Much thanks again to Carl
Professional company- Very happy with technician’s service, plus on time with service call reminder letting me know a technician was on the way.
Awesome local company. They have installed for me and maintained my units for years. Honest and professional!
O’Callaghan has been our HVAC service provider for more than a decade. They’ve consistantly demonstrated friendly, reliable expertise, keeping us warm in the winter and cool in the summer.
Great company. I trust them with the key to my home. Carl is top quality tech. I recommend them to anyone. Great prices
Everything was done In a professional manner. Technician was very courteous
Carl is great, extremely professional and friendly. Can always count on him to take care of our HVAC needs.
O'Callaghan came out to fix a leak I had in my AC system. They were able to make it out same-day. My service technician Carl was great. Immediately diagnosed the problem, explained the fix, and repaired all in a very short period of time. Pricing was reasonable and work top notch, as is typically the case with O'Callaghan. Highly recommend them for anyone needing HVAC service in Atlanta.
