Forget the equipment for now, the service is exceptional. When installation is complete, one would never know workmen were here. Everything is cleaned up and all done courteously. The equipment recommended is of the highest quality too.

Best to all. Roy

In January 2015, my home heater stopped working and your company promptly sent a very kind and knowledgeable advisor named Denny. He inspected the heater and explained to me in detail and without pressure that being a 17 year old system, he would make the needed temporary fixes, but the heater would eventually need to be replaced. I then decided it was time for a new heating and air conditioning system to be installed. Due to the chilly weather and I am 86 1/2 years old, the next day very courteous installers named Chris, Juan and Ruben, cautiously and neatly installed new systems in one day! Everything works beautifully, and I am so pleased. I thank your company for the immediate response. I am sincerely grateful!

The Fairfield City Inspector asked who did the work; I responded "Greiner." He said a very good co.! I added I was referred to "Greiner" by Mr. Steve Pearson of Pearson's Appliances of Cordelia, CA. With references like that my comfort level was elevated! Thank you

Very professional. The guys were on time, took precautions to protect our floors & walls, worked hard all day, were courteous and polite, and basically left us with denuine good feeling about the home installation. Didn't see one young person on their stupid cell phone all day. Very satisfied!

* Nathan is very knowledgeable...
* Everyone was very professional and was prompt with any questions, etc...
* No matter how many questions we asked Nathan + Rick were very patient
* From the office staff to all others - very willing to help and prepared us for this process.
* With the rain delaying installation of solar - the Greiner team was willing to do what they had to - to allow the committment to be met.
Thank you all for making this large project simple for us. We are so excited to no longer have to pay outrageous PG&E bills!

Greiner's service, technical expertise, qualified / certified technicians, workmanship & staying on schedule represent truly 5-star performance. After installation, ongoing service is also a plus. We had a 52 panel solar array, 2 dual fuel furnaces & electric water heater installed. Ruben & Rick are great project managers.
