    "We decided to replace our 16 year old AC and furnace as we wanted to prevent possible problems with our HVAC system. The heating consultant that they sent, Alex H, was very friendly and knowledgeable. He provided us with estimates for a number of options - similar to those from other HVAC companies that quoted for this work. A day later I received a call from Blue Dot offering a discount on that quote and we accepted that quote. Alex made the one and a half hour drive to visit with us again, to walk us through the contract details, and to explain install process. This was a really nice touch as usually contracts are signed electronically these days. The Blue Dot install team came on time on the scheduled day and did a neat and professional job with the install - performing all the necessary checks and tests, and left the work area clean and tidy - and with the HVAC systems working well. The whole purchase and install process couldn't have gone smoother. We are very happy with BlueDot and will certainly use them again preferentially for our HVAC needs."

    "I had to call them on Sunday afternoon. They were very prompt in responding. The owner came out with short notice and fixed the problem very quickly. He was very responsive to my repair request. He was very knowledgeable. He looked at the unit and after the first trial, my unit was fixed. I could not believe it. Their pricing is very good and actually better than most other companies. I asked about a few services and he gave me his honest feedback. He said some services I do not need and gave me some money saving tips. You cannot find other companies like this. For sure a very good company you can trust. I highly recommend them. UPDATE: 02/21/19 Furnace / Forced Air Heating System - Repair or Service **** I have been using JDL HVAC for over a year. They are very prompt. And they are great for emergency service requests as well. They are very responsive, honest and reasonably priced. I highly recommend them"

    "At least 5 other companies said that they could not handle the job because our air handler was in the attic and the opening for our stairs was too small to take out the old handler and put in the new one. Air Master Heating's expert, Ken, laughed out loud about that. He said that it would be no problem. He did calculations and we solved the problem with a high efficiency unit. Ken was the estimator and led the installation team. Everyone on the team was hardworking and respectful. They installed the system, cleaned up well and were a pleasure to have in our home. The system is working great and has been very energy efficient. I would recommend this company without hesitation!"

    "It's a few days after the first measurable snow fall we've had in the northeast in several years and my heat pump outside unit stopped working. I switched the system to emergency heat and started making calls for help. I got in contact with Will from Air Distributor HVAC and he was able to expedite my service request and got to my house within 1 hour. He gave my system a comprehensive look, diagnosed the problem with a high degree of confidence and provided a fair quote for fixing it. He applied the fix and then much to my surprise (and appreciation) he waited an extra hour to ensure there were no other contributing factors that could present a problem in this freezing weather. I appreciate his expertise and professionalism, but also his willingness to go the extra mile to ensure my family is comfortable. All my future HVAC needs will referred to Air Distributor HVAC. Will, thank you very much for a great experience!"

    "Moises, the company owner, is incredible. I called 5 HVAC companies to get quotes for full system replacement, and MSR was not only the most responsive, but he came out the very next day. He gave me an incredibly competitive and fair quote for my project, and we immediately gave him our business. Unfortunately, our AC died before he could do the work, but he came out to our house at 6pm on a Friday to drop off a portable AC unit so we wouldn't sweat all night long. We thought we'd be stuck without central air for a few days, but Moises came and worked 9 hours on a Saturday to replace both our furnace and our AC unit. Afterwards, he even gave us a great price on a yearly HVAC maintenance plan. MSR is run by an honest, hard-working tradesman who understands what customers want and need. I won't hesitate to recommend him to friends or to anyone who needs HVAC work done."

Anyway I scheduled a 10 am appointment for Friday November 28, 2008 and they were very prompt. The techinitian expalined the issue and my heat was up and running within the hour.
