"Mr Chortani is a real professional. He is reliable, honest and knows what he is doing. I spent two days with him while he replaced my boiler. He thinks first then does what must be done without making any mistakes. He does not waste time or material. He did exactly what he told me he would do. All contractors should be like Mr Chortani. If you need "The Best" go with Chortani Services HVAC. Thank you Mr Chortani!"

"Joe was courteous and accurate during all steps of the process from estimating the project including the 2 lbs of additional coolant needed to raise pressure in my HVAC and all other work including fixing hard to reach attic ducts, achieving the estimated cost exactly. He was also a pleasure to speak with and I felt safety was done right at all steps for himself and myself the home owner."

"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"Highly recommend Allined Mechanical! Billy and his team were able to come over and assess our existing central air system pretty much right away. He was super informative, not pushy (which I have dealt with in the past). Replaced our compressor and got our system up and running in no time. Great customer service, we will be using him for all of our hvac needs from now on!!"

"Anthony was so helpful, knowledgeable, and kind. He hung my light fixture perfectly as well as replaced some switches that weren’t in the original job. I will have him back for any electrical work I need and highly recommend him."

"Chris was great. He gave an estimated arrival time and kept me posted about when he would arrive. Once he arrived, he was very professional and respectful of my home; he didn't even mind my nosy cat. He gave me an assessment of possible repairs needed on my portable AC, gave me an estimate for possible costs and provided an invoice on the spot. He made the whole process very easy, and I appreciate the time he took to explain everything. I would definitely hire DG HVAC & Home Services again for my appliance repair."

"We were fortunate enough that we had Mike, who assisted in completing the installation of an ACiQ HVAC system that had been attempted but failed by another business. He was able in getting this highly automated, fully computerized, next-generation modell ACiQ HVAC system up and running. Iâ d like to emphasize that multiple companies refused the installation claiming that this system was too complex and they have no experience. Mike took the time to look into it, understand it and make it work. Excellent job, I would highly recommend him."

"This was a multi project visit: upgrading and running a stove line, upgrading my service to 200amp and replacing the outdoor sub panel for the pool filter. Cole was great! Responsive, visited and provided a detailed estimate of each job and showed up quickly to resolve. Would highly recommend"
