All Phase Heating & Air Conditioning installed a new air conditioner in our home. Their prices were better than the competitors. They were able to schedule the install within 2 weeks. They were prompt, professional, nice and really good at what they do. I highly recommend them for any heating and air needs.

Great company! Had All Phase replace my AC system and the experience was fabulous from start to finish. The office staff were so helpful and professional and the installers were clean, courteous, on time and did a grade A job! Can't recommend them enough!

Brad, Craig, and Brian were all extremely professional and knowledgeable. I’m glad I took the time to get multiple quotes so I could find these guys. All Phase rocks!

Had a Fujitsu ductless system installed this week. Everything was flawless from when they said they would arrive to the installation and clean up. Salesman and installers were all knowledgeable, helpful and easygoing. I would recommend this company to anyone without reservation.

I hired All Phase nearly two years ago for 2x per year maintenance of HVAC systems. Their service people are sharp, prompt and friendly. They offer tips so I can help with maintenance between their trips. To date they have not generated ANY recommendations for additional services -- i.e. additional billing - which is so common (think about your recent oil change and what other services were suddenly 'needed!' lol) Highly recommended.

Wonderful customer service, professional responsive repair/replacement quotes and highly trained staff that explain what is happening with your system and what they can do to get you working home heating and refrigerated air conditioning. If you purchase a replacement system, I recommend that you include a winter/summer on-site maintenance contract to prioritize the All Phase Repair Team response, providing factory OEM replacement parts carried on their trucks and reduced parts replacement costs. Don't delay..they are honest and a local Grass Valley Business that really cares!!
