Oleg did great work. First, he did a diagnostic at no charge. He then followed up with a few different options for a replacement air-conditioning unit. His estimates were much less expensive than those I received from other vendors. He was back within two days to install the new system. Very friendly and knowledgeable. I highly recommend. 5 stars.

Oleg was the best. They were very professional and fixed my prob in Less then 20 minutes . Oleg tuned up my aging air conditioner and topped off the coolant. It’s now running better then ever and the house getting cooler faster. I would recommend them again and again.

Excellent immediate service! Oleg is a professional who diagnosed a problem that another technician completely missed and detected a dangerous malfunction in our AC system. Thorough, professional and excellent quality service.

Oleg was professional, quick and honest. Installed our ecobee thermostat with great service. Highly recommend!

Amazing service, he was on time and on the job always with a smile, he answered all my questions and great price as well, super recommended

I had an excellent experience with GoTech, specifically with Oleh, who helped move our furnace to the attic. The service was top-notch in terms of quality, reliability, and speed. Oleh was highly professional and efficient throughout the entire process. The job was completed quickly without compromising on the quality of the work. Great job!
