I entered into a service contract and scheduled mote maintenance work for next week. Highly recommend the Company in general and Nick specifically!"

"Holtzople installed a new HVAC for us in Nov 2025. The furnace worked like a champ all winter. As the weather warmed up today, we turned on the AC. Not working. Called Holtzople for service and the intake was a smooth process. Got a call from Tim, who was in the area on another call. He came by a little later and did the systematic troubleshooting. Isolated the issue to a defective sensor. After 2 hours of persistent effort, we are up and running. Great company. Highly recommend them. Been a customer since 2002 and only good experences."

"The technician was knowledgeable, efficient and friendly. "

"I appreciate the experience, expertise, knowledge and integrity of this business. The home I live in is very old and I am a renter with very little knowledge of HVAC services. Sean, the serviceman, explained clearly what the issue was with the furnace and even provided advice regarding CO detectors, that I should have more than one. I am very grateful for the service he provided and I definitely recommend his company."

"Great service very prompt and easy to work with."

"They did a great job. "

"Was able to get a technician on site next day. Showed up about 30 minutes into the time window. Diagnosed the problem in roughly 10-15 minutes, had it fixed within the hour. Very professional, great job."

"I reached out to Angi’s to find a HVAC company to help with my AC that was blowing hot air in the summer. I got super lucky when I found MSR Heating and Cooling. They arrived on time and assessed my situation. I appreciated the time they took to explain the issue in ways I understood as well as recommend the best option for me. The estimate quote was fair and there were no surprise expenses to repair my unit. I can’t thank the owner, Moises enough for a job well done. His professionalism, knowledge and skills are reflected in the quality of work performed. I would highly recommend this company for your next repair. "

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself!
