I highly recommend! They are honest, reliable and the employees are all very friendly and professional. I had a new unit installed and I am very pleased with it. They did an awesome job with the installation and very quickly, too. Their customer service is excellent from the office personnel answering the phones to the repair guys that come to service your A/C unit.

I wish I could give them a 10 star rating! They are the best! They installed our system and have maintained it from that point. On a Saturday afternoon around 2 our system stopped working. I called them and got their answering service. My reaction was I would not hear from them until Monday. Was I wrong within 10 minutes I received a call from them, I explained the issue and he had a service man at our home within an hour.

Not sure if anyone is looking to  get air conditioning installed, but if anyone is in the market, I highly recommend reaching out to Jon McLaughlin of Left Cost Heating & Air. He gave us the best quote for A/C and I was honestly shocked at how reasonable he was compared to all the others I reached out to and how quickly  the turnaround was to get things done. He’s super personable and communicative, the work was clean and well done. 
If you are looking for someone, reach out and have him give you a quote. Seriously so thrilled  with how things were done. 
His cell is 510-227-7451 and email is jonleftcoasthvac@gmail.com
