Greiner Heating & Air Conditioning

I’m new to Greiner. I checked several companies when I needed a new furnace and AC. From the first phone call to the end of the installation, the staff at Greiner were professional and helpful. Every person I worked with was knowledgeable, met their commitments, and got back to me promptly as needed. The installation went smoothly. I’m looking forward to having Greiner take care of my maintenance needs going forward. What a pleasure to do business with such a helpful and professional staff! BTW I got three bids. Only Greiner mentioned that my ductwork needed improvement and they took care of that, too. My tenant says the airflow is much better now.

Greiner heating and air has maintained our two HVAC systems for over 10 years via an ongoing service contract. Their performance and quality of technicians have been excellant. With their Five-​Star track record, we had them covert all our HVAC and water heating equipment to SOLAR. Initially we were focused on just installing solar panels to reduce our electrical bill. Along with this, our furnaces and air conditioner units were over 20 years old and in need of replacement. Greiner’s experts had us take a look at a «whole house green» design solution for our energy needs. Additionally, Greiner staff provides a wealth of information on all federal, state and PG&E programs that are available to home owners that fund projects and/​or consist of rebate options. We received a substantial tax reduction and rebate from PG&E. As a result of their recommendations, we had them install 52 solar panels on 2 ground mount array structures that are designed to withstand a 110 MPH wind, 2 — duel fuel (gas & electric), high efficient HVAC units, and an electrical energy efficient water heater that’s designed for solar operation. Our electrical bills have immediately zero’d out with $ credits back from PG&E. This was a large project and Greiner executed it with excellence. I worked in an engineering department of a large global corporation and found the Greiner tech staff and project manager performed with the same level of knowledge and skill I had experience with during my project work in large plants, refineries, and heavy commercial facilities.
I know of at least 4 neighbors who had solar systems installed by Greiner after our system was installed. Greiner uses high quality, commercial grade equipment for all their work. Their designs, materials and workmanship leads to systems that can really last 20+ years. Their design and construction approach is «not to cut corners with materials and installation techniques.» For example, their design practice is to install an inverter for EACH solar panel, as opposed to many companies who cut costs by using an inverter for 4 – 6 panels. This cheap approach cuts costs but, after years of experience, professionals have found that single inverter clusters will typically fail. Installing an inverter for each solar panel also enables efficient monitoring, and diagnostics. Greiner made me aware of the reasons for this design practice and a multitude of other DO’s and Don’ts that led to an installation that’s trouble free. I can monitor the performance of my system on my laptop, tablet or cell phone via email/​Internet. Greiner truly delivers Five-​Star performance in all aspects of a project, such as: Educating the home owner, equipment selection, installation, quality technicians, project management, communication on project status, and meeting their forecast completion date! Greiner starts a job and completes it as forecast. They are «tenacious» about staying on a job until it’s finished. NO CASES of me asking, «where is the contractor at» When our project was started it was sunny. Then a two week period of torrential rains followed. Rain did NOT stop Greiner from working. The project manager arrived with a 6 man crew. They worked under large rainproof canopies for 2 weeks and continued until project completion. They completed the project on time with excellence.

As a previous Service Technician of Greiner, I received specialized training in how to create more efficient HVAC systems by improving airflow and addressing the one issue many companies either don’t want to deal with or don’t understand: DUCTING!
I learned a great deal during my time at Greiner, enjoyed working with their great customers, who understand quality, thorough service.
When people ask for a recommendation of who to call, I continue to refer them to Greiner.

I paid over $ 7000.00 for a new heat and air system including new vent covers. I needed to remove the vent cover screw heads were totally striped out call and was they told me they use old screws… I paid for new vent and they don’t come with new screw? whats up with that???

I just want to say how happy I am with Greiner today! I have also used them in the past and always have had great experiences. Today they installed a new water heater for us did the estimate in the morning and install in the early afternoon. Kudos to Shaun Satterwhite for making this happen. Would not hesitate to recommend to friends and neighbors. C. Cisneros — Suisun City

I keep hearing Greiner ads on the local radio station and the company had recently helped out the local SPCA so I thought I would give them work. My Mistake! I sent them to a rental and the guy calls me and tells me that I need a new circuit board and the unit is filthy. Total $ 1,200.00 but if I buy their maintenance plan, I will get a lower price. I told him that I needed a second opinion, which irritated him. I got 2 more opinions and both companies said my circuit board is fine! Total cost for repair was $ 350.00. The unit was clogged and dirty.

Nice try greiner. But you are a bunch of charlatans. The service man did charge me for a full hour. He did spend a good portion of his time on the job trying to convince me to buy into their service plan. I still had to call out another company to get it fixed right and I dont work for you compeditors. I do work in the remodeling industry and your company does have a horrible reputation. Blakes is just a better company i have used them for a couple other services as well they are always courteous and very professional. If you want to see the difference just see how many complaints that Greiner has with the BBB. Its not just me.
Maybe you should call the IRS i hear they have a couple of openings for people to cover up their miss doings.

We had a solar panel system installed by Greiner. I researched this a fair amount and talked to 3 companies including Greiner, as well as customers from all 3 companies. Greiner had replaced our HVAC system earlier and we had a good experience from that; their prices were competitive (one Elk Grove outfit quoted a price double the other two); and Greiner used modern panels with micro-​inverters, avoiding the large inverter box on the side of your house. They also managed to run the wires through the attic, so no ugly conduit on the side of the house.
Only glitch was the system failed the first building inspection because of what I consider to be very minor issues (missing label, etc) but Greiner is coming out again to fix the issues. They have always been very responsive to correcting the inevitable glitches. I’d use them again, no question.

We just had Greiner’s come out at the end of October and install a whole new heating and air system plus a new water heater. I couldn’t be happier with the service I received… the value I received… and the quality of the products I received!
The work was done in a day and a half which is very quick! And when the Inspector from Vacaville came out to inspect the work, he was very happy with what he saw! He signed off on my Permit and we were done! And the best part of all is that I received a $ 2000 Rebate in check which I will be getting in a couple of weeks! So now I have money for Christmas presents! Lol!
I would recommend Greiner’s to everyone!

Our air conditioner quit working during a heat wave, and when the technician came out, he didn’t do anything except for look at some wires and the breaker, which was a little loose. The ac turned on again, and we were charged the $ 80 service fee for 2 minutes of «work». A couple of weeks later our ac went out again, and when I tried to flip the breaker, the breaker popped and sparked and shut the whole house’s power off. After replacing that breaker, we found that the wiring was not connected at all, and the electricity was having to jump across a gaping hole! We are extremely lucky that our house didn’t catch on fire! In my opinion, the service technician should have taken a closer look at the electrical issue instead of trying to sell us a brand new unit! I will not be calling grenier for anything again.

I have used this company for several years — I subscribe to their continuing service plan for $ 11.95 a month, and they come twice a year to service both of my air conditioners and both of my heaters for no additional cost. They wear booties whenever they come into the house and are competent, respectful and professional. I would recommend them to anyone who needs service. I do have to admit that this year, when they moved items in my 3^rd bedroom to access the upstairs heater in the attic, they pretty much messed up everything in the room and didn’t even try to replace anything where they found it — but they technically aren’t supposed to have to move anything, so I can’t complain too much. (My house is 22 years old and they have replaced both of my heaters and air conditioners with a very reasonable price and great service — didn’t try to sell me the most expensive alternative, and did a great job each time.) I don’t remember the individual’s name who was here last time, but whoever it was did a good job and I would recommend him as well as the company. (Not sure if it”s just an unusual coincidence, but I am not the same Randi H. that posted a negative review about them!)

No free estimates. We did not thrust their assessment after reading some other reviews anyways. It was too late when we already made the deal for a new system. (Carlos here, too.)
Then… Two different holes on the roof (found at two different times). Ceiling had to be painted after the rain. The new system broke TWICE because they did not do the basic installation right, we were left in cold. The front door was left open when they left after the first installation although we asked many many times for them to call us after the work is done. People had to come to our house home 8 more times for the repairs after the installation.

Great service! They were competetively priced and found someone who would finance me. I will gladly be back for services in the future. Betty was so nice too :)

my return air duct collapsed and called them up to get a estimate to it replaced and they came out and gave a estimate and told me that it was gonna cost 760 dollars to replace the duct and told me that its not guaranteed to work and so i decided to call a few other places and to give me a estimate and found out that had came out and was unplugging stuff on my heater to get me to buy a whole new system. heater and a/​c. worst service ever!!! by the way the repairman was carlos so watch out for him and watch him at all times id give 0 stars if i could

Greiner Heating & Air was referred to me by an employee from Lowe’s in Vacaville. The following day after calling Greiner, Dan came to my home to do their free (at the time) estimate for repairs. Dependable charged me $ 65. Dan explained that the older R-​22 outside AC unit I had was no longer availble for use in CA. He showed & explained the best possible route for the AC repairs for my home. He wasn’t pushy and didn’t try to sell me a complete overhaul of my heating and AC, just only what was needed. Long story short, Greiner sent over 2 very courteous and professional technicians (appreciate the great service Heladio & Hector!) a few days later and installed a new R-​140 unit and evaporator coil in my home. The new system cools down the house in ½ the time it took the R-​22 unit, uses less power and runs quieter. Great job Greiner!
