"McCarthy installed a replacement A/C and air handler. Joseph did a great job walking us through everything, and the install crew followed through with all of our plans. Everything went smooth, and we highly recommend McCarthy!"

"JDL HVAC Services was the contractor provided by our home warranty company to repair our heating system. The were initially prompt and came out to the house and attempted to diagnose the problem. The technician though the problem was the circuit board and JDL delivered a replacement from Carrier the same day. Unfortunately, the part did not fix the problem and the technician thought the replacement part was defective. Unfortunately, it was Friday and Carrier wasn't open on the weekend. I specifically asked the technician what would happen on Monday and was told that JDL would get a new part Monday morning and then come to the house immediately to install it. This was very important since we had no heat on Friday and over the weekend and the temperature dropped below 20 degrees at night. Monday was a disaster. Unknown by us, JDL called at 7:30 a.m. and when we didn't answer, they removed us from their schedule. At 8:30, we realized they'd called, and contacted Joe and he added us back to the schedule, but in the afternoon. When a new (more experienced) technician showed up, he did NOT bring any replacement parts. When I called Joe to inquiry why the technician had no parts with him as promised Friday, he said he wouldn't buy another part because he couldn't get a refund on the first replacement circuit board. He also wasn't convinced the heater circuit board was the problem and wanted to do more diagnostics. I also asked Joe why they didn't come out in the morning as originally promised, and he had the audacity to blame us for not answering his phone call which we had no idea to expect. He also blamed his technician for providing us incorrect information. He did put another employee on standby to get parts from Carrier once the new diagnosis was complete. The new technician found another part that had failed and it was delivered with the original replacement circuit board. Both replacement parts were installed. While the technicians were friendly and informative, Joe was rude and lacked friendly or acceptable customer service skills/friendly. He also does not keep his technicians informed (the new technicians couldn't answer any of my questions) and it did not appear the technicians speak to each other when they transfer a repair. Overall this was not a positive experience due to the poor customer service from Joe. He did call an apologize (left a voicemail) after the repair was complete."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Rob Rhea was very professional and showed exceptional workmanship when replacing and installing my Aprilaire Dehumidifier. He came to my house on 3 different appts. and was prompt, on time and called to let me know he was on his way. Also very knowledgeable. I would recommend him to any of my community neighbors. Thank you Joe Schiavo"

I'm soo happy I chose Blue Dot !! Also the price was unmatch... Thanks !! PS... The Wife is back to calling me HONEY again :)"

"It has been said, that with every great success, begins with a single small step. Recently, I was faced with my home's central air system failure. Upon review, by my previous contractor, the system could not be repaired and would need to be replaced. Faced with major cost replacement, I used Home Advisor, to select a professional that could provide an estimate for providing needed replacement. I selected Hunt Plumbing and Heating, based on reviews and performance in our community. I could not be more pleased, Mr. Hunt provided a team with the knowledge (Matt and John) that displayed they had the ability to perform and the goal to complete this project to our mutual satisfaction. While it has only been two days, I am satisfied with the outcome and the quiet running of my Rheem Air unit.. Since Hunt is a 5 star rated company I am sure my rating will not mean that much. But I do send to you and your team my thank you for your service to my needs and I will recommend you in the future. By the way, Mr. Hunt the extra water bottles that you left for your team are now mine. Have a good day."

"While the technician who ultimately serviced my system was efficient and informative, the overall experience was unacceptable. It took nearly 18 hours and three separate appointments to replace a single fuse under a warranty installed on November 4, 2025. The dispatch, scheduling, and supervisory staff were dismissive and unresponsive, demonstrating a complete lack of customer care. This was, without question, the worst customer service experience I have encountered. Additionally, the failure itself appears to stem from incomplete installation guidance, as I was not properly advised on potential system vulnerabilities (such as power surges). While I appreciate the technician?s work, the breakdown in communication and service at the management level makes it difficult to recommend this company."

"They technician was punctual professional and clean. they gave me good advice about problems that they foresaw with the HVAC system, but I want ready to do that yet."

"Travis Grove contacted me less than a minute after I submitted a request. He came day-of on a Friday afternoon to inspect, and quickly found the capacitor had failed. He had a replacement on hand, though the issue was the fan as well. Travis made sure to keep me informed of parts availability (fan vendor closed on weekends), and text me updates. If his arrival time changed, he made sure to let me know. The new fan is more powerful, to provide better cooling. He noticed my refrigerant pressure was low as well, and made sure to fill it up. Travis was friendly and easy to talk to. His price was very reasonable, including all parts and multiple hours of labor over two days. My system is working well and cooling better than before. All set for the summer heat!"
