Definitely

From start to finish the service was exceptional. Alex came out and evaluated the problem with my heating/air conditioning system promptly. The guys (Nick & Ruben) that did the install were very nice and professional. Two weeks later, I became ill with the flu and was so happy to have my heater working while I was sick. The basics of life are still important.

 Danny was extremely helpful (without being pushy) in explaining and offering us options for our old HVAC system. He sold us a new system without "selling" or being a "salesman". Dennis and the entire install crew Robert, Christian, Christine, and others were very helpful and professional. Yes, it was like a family experience. Thank you all!

P.S. Office staff with phone contacts and updates was very much appreciated as well.

 The Greiner employees are the most thoughtful and professional people I've ever dealt with. From their "little booties" to walk mats on the carpet, they left no sign of being here except for an excellent A/C system that works great. Thank you Greiner.

All the employees I dealt with were great. They even came back the 2nd day due to additional work needed to replace the old 1977 freon lines with no complaints or extra charges. And the equipment works great!! I'm very satisfied.

A no pressure approach to educate us about options to get our HVAC and water heater fixed and replaced. Then they did what they promised at the price they promised.

 Quality product, exceptional employees. Karoline was outstanding - all were personable, respectful, knowledgable. We appreciated the "booties" over the shoes, floor covering and the vacuum clean-up. 

P.S. Thanks for the Starbucks
