"The replacement of my a/c ( with indoor coil) and furnace was handled in an extremely professional way. Holtzople Heating and AC helped me to find the best replacement units for my 20 year old Trane system. I am impressed with the knowledge of the sales person sent to provide quotes. I am also impressed by the skill and meticulous care that the installers took while replacing my entire heating and cooling system. Within a day, they took out my old system, installed the new system up to factory specs, tested and made sure all phases of heating and cooling were functioning as they should, and cleaned up, taking away all of the old unit, leaving nothing behind. The last thing the head installer told me was that a quality control team would be in touch and be coming in within the next two weeks to make sure everything was continuing to operate as it should. This attention to detail, and customer satisfaction is what has impressed me the most about Holtzople Hearing and A/C."

"The whole house could hear the vibration when our two year old Tran xv20i heat pump was at 67% work load. It seems the issue started from day one it was installed. Tried to reach out the installer but they went under. In June, I called McCrea. Mark Dzbynski came over, carefully checked everything and then concluded that refrigerant was not charged to the correct capacity. He explained that our system line is longer than usually and additional refrigerant is needed to compensate the length. He carefully calculated and addded the correct amount based on the temperate & length. From June and Oct, the vigration never came back. No one can tell when the system is on because it works so quietly. I really appraicate the work done by Mark and his work ethinics. Very pleased!"

"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."

"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 put in a new system. They had to take everything existing out. They showed up when they were supposed to and finished in a week. They were clean and efficient. It was not an easy task. They cleaned up after themselves. Very professional. The owner explained everything to us."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"My experience with him was top notch. He was accommodating to my schedule. I work nights and he was willing to come to my home in the early evening instead of normal business hours. He assured me the fix of the leak would hold until the end of summer but there was a chance that I may need a new unit next summer since the unit is over 10 years old and the leak was pretty severe. I had no other trouble with the unit the rest of the summer. His price was reasonable and he was friendly and efficienct. If I need a new unit next summer I will definitely use Tetteris Heating and Air for the replacement."

"Replaced air conditioning unit. Super nice brought us portable a/c units until installation was completed. Very professional and easy to deal with."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."
