A-1 Heating and Cooling - San Jose

I contacted A-1 Heating and Cooling to assist with installing a smart thermostat for my dual-mini-split system that currently has a wired thermostat. Their scheduling was easy and quick and their availability was great, and their flat price for my project was competitive and fair. Their follow up with confirmations felt reassuring and began immediately. Their technician could not finish the work on the first visit, but he was more than competent, he worked the problem well, had excellent customer service skills, and I felt my issue was his priority the entire time he was in the house. I went away from the licensed HVAC company who installed my system to go with A-1 Heating and Cooling, and I am so glad I did because I much prefer dealing with how friendly and professional they have been thus far.

The best plumber ever. Brandon was great. He was able to perform a leak detection and find the leak in the slab. He was careful on the cuts of drywall. Performed a perfect repair. Cleaned up work are after completed. Great service at a great price. Highly recommend Brandon

I work for a boutique real estate company and A-1 Heating & Cooling we’re fast, thorough, and transparent throughout the estimate process. Sally provided multiple quotes for different furnace models that were extremely helpful for our clients. We stressed their efficiency and are hoping the new owners use A-1’s services. We will definitely be using them again!
