Customer Reviews

Todd Katz

We had a wonderful experience with Qualtech, which advised us and installed two Carrier low-NOx furnaces in out attic. Daniel talked us through our options and ultimately helped us select the appropriate equipment for our needs. Elijah and Erie did a really great job during the install and went above and beyond. Erika coordinated the entire job and was incredibly helpful and knowledgable on the phone and via email. Qualtech was recommended to us by experts in the HVAC industry as a very honest company with great training and service. My experience with them confirms they deserve this outstanding reputation. Thank you Qualtech team.

I had a wonderful experience with Qualtech Heating and Cooling installing a new mini-split system in my bedroom. From the initial consultation to final installation, the entire process was seamless. Erika, the office manager, coordinated everything with great care and professionalism. Daniel and Myriam, the owners, brought deep knowledge and efficiency to the project, and the installation team of Wilson and Josue delivered excellent workmanship. I’m very pleased with the results and highly recommend Qualtech for their outstanding service and integrity.

A truly fantastic experience getting our Carrier new heat pump installed by Qualtech. What sets them apart is their dedication to customer service. Daniel was awesome in explaining all my options during first visit, Erika was very professional and handled all my questions after that. The installation crew was not only skilled but also extremely polite and professional. They showed up exactly when they said they would, and their focus on a quality installation was evident throughout the day. They worked quickly, and the work area was spotless when they left. The new unit is running quietly, and the difference in heating/cooling efficiency is already noticeable. If you are considering a heat pump, I would strongly recommend Qualtech—they are honest, knowledgeable, and make sure the job is done right. Thank you to the whole team!

Linda McCann

We are very happy to alert the public to what a great company Qualtech Heating and Cooling is! Finally decided to get a modern mini-split system and was expertly guided by the owner, Daniel. He had such patience coming out several times to reassure us of the correct placement of each unit. Their project coordinator, Erika Thompson, kept our permit and paperwork in order, while continually communicating with us. She was a super star, always available to answer any questions and helping with rebates! Myriam Rios made sure our contract was correct and on time. The real stars of the show were Elijah and Wilson, the installers. They went the extra mile, making sure the connections were protected and safely installed in difficult areas. The unit outside blended perfectly with a great paint job (thank you Eika for making sure they had the correct paint). Qualtech has put together an incredible team and makes loyal fans of their clients! Thank you Daniel, Myriam, Erika, Elijah, and Wilson. Great job, The McCanns.

I recently had my 32 year old heat/air unit die on me at the peak of summer. After getting quotes from 3 installers for a Carrier unit (all 3 found on Carrier’s site), I selected to go with Qualtech. Not only were they the cheapest, the other installers actually tried to sell me units from other companies that I did not want. I was a little wary that the quote I received from them was almost 60-70% of the others, but their reviews were good, so I went with them, and I could not be happier. There were no hidden surprises at any step and the process was seamless. Daniel heard my requirements and preferences with patience, and walked me through how the whole process with work. He spent time looking over my existing install, and told me what would need to change. The install team led by Eddie were prompt, courteous, and clearly knowledgeable about their work. He took the time to explain the system and answer all of my questions, making the whole process stress-free. A special shout-out to Erika, my project coordinator, who truly went above and beyond. Not only did she ensure everything ran smoothly, but she also helped me access rebates and savings opportunities that I wasn’t even aware existed. Her expertise and willingness to assist made a real difference and saved me extra money, right down to adding removing my fireplace to get access to significant rebates and even coordinating with the government agency to get that rebate approved. She also ran my entire permitting process with zero faults. I’m also grateful for her friendly support that made scheduling and follow-up a breeze. Overall, this was a fantastic experience—great product, great price, great service, and genuinely helpful people. I highly recommend them to anyone in need of a new heat pump AC + Furnace units!
