- SSSaket SinghaniaNov 9, 20255.0I 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!

Daniel and Erika were amazing — always available to explain things and answer all my questions. Wilson and Josue did a fantastic job with the installation. The whole team was professional, and really cared about getting the job done right. I’d recommend them in a heartbeat!
- APAnil PatwardhanOct 16, 20255.0Prompt service and great communication. They new exactly the right solution for a heatpump to function in my small space. They gave a competitive price and were efficient and thorough in the installation. On top of that Erika seamlessly make the entire process (even post installation) go smoothly
- MGMendi GunadiOct 15, 20255.0A 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!
- GDGinny DaviesOct 8, 20255.0I 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.
Frequently Asked Questions About Qualtech Heating & Cooling
Are all air filters the same?
No, there are a variety of sizes and types available and it is important to select the right size for your system. You should also look at the filter's rating. A high rating removes more particles from the air, but some can restrict airflow.
Once you have the right filter, make sure to change it regularly.
Do I need to schedule regular maintenance?
Yes, regular maintenance is essential to keeping your HVAC equipment running all year long. Routine maintenance helps prevent breakdown, ensures reliable performance, optimizes energy efficiency and maximizes your equipment's lifespan.
How can I eliminate odors in my home?
Odors in your home can have a variety of sources, including air ducts. Dirt, dust, mold and other debris in your ducts can create a stale, musty odor in the air.
Air Scrubbers can help improve your indoor pet, cooking odors and more!
How can I know if my indoor air is dangerous?
If you've noticed that your allergy or respiratory symptoms go away when you're out of the house, then return when you're back home, this can be an indicator of an indoor air quality issue.
Indoor air quality can be contaminated by:
- Dust
- Humidity levels that are too high or low
- Miscellaneous pollutants
- Mold or mildew
- New carpeting, paint or furniture
- Pet dander
- Smoking
- The presence of chemicals
How often should I change my air filter?
It varies, depending on the manufacturer's specifications. Usually, it is recommended that the filter is changed monthly, especially during heavy use seasons.

What is a zoning system?
A zoning system has one HVAC system designed to provide heating and cooling to different zones of the house. Dampers are installed in the duct system to redirect air to the specific areas it is needed. Separate thermostats are used to control the temperature in each zone as well.
What causes ductwork to pop?
Popping noises can be caused by movement in the ducts when airflow causes a sudden temperature change. This can be a sign that your duct system is undersized for your home.
An undersized duct system may also cause issues with leaky ducts and reduced airflow. This can cause mold growth and decreased indoor air quality.
Why is my air conditioner freezing?
This can be attributed to insufficient air flow, dirty evaporator coils, low refrigerant level, motor malfunction, or blocked vents and registers, among other causes.
