Late March 2025, Qualtech replaced my old AC and Gas Furnace with a Carrier Heat Pump. Qualtech has always been great and provided excellent customer service. The new unit was installed quickly within a day by the technicians. Estimator Daniel was great and climbed up to the attic to check the ducts if they were still good and no leak.

Finally needed home A/C in the Oakland Hills. My house is a unique A-frame that required unique solutions. Daniel, the business owner, came out twice and did two sets of estimates, and Erica was very responsive and patient in reviewing the various equipment solutions and answering my questions. Techs Elijah and Sergio worked hard and did a great job on the installation. Qualtech was one of three estimates I got -- glad I chose them!

We had a very positive experience from beginning to end with the replacement of our HVAC system. The response was prompt and Omar gave helpful and clear advice and information with which to make our decision. Elijah and Sergio arrived the next day (during a heat wave, of course!) and completed the entire install with a minimum of disruption. They were both professional, pleasant and clearly very capable.
