Kody was fantastic! He spent several hours with us, patiently going over our options and helping us figure out what made the most sense for our home. As it turned out, the best option was a completely new system, which was definitely a bigger decision than we originally anticipated. What I appreciated most was that Kody never made us feel rushed or pressured. He was kind, patient, knowledgeable, and took the time to answer all of our questions and walk us through the details. And then they really impressed us with how quickly everything came together. They were back the very next day and the day after as it was a two day job, with a full team of installers and replaced the entire system, including new ducting, insulation, and everything that went along with it. The crew worked hard, was professional, and got the whole job done efficiently. Replacing an HVAC system is definitely not how anyone wants to spend their money, but having a team that makes the process this easy makes a HUGE difference. We couldn't have asked for a better experience with Kody and the installation team. Highly recommend! read more

I just had the second floor HVAC system replaced by Greiner Heating and Air today and all I can say is Wow!!!! Another great job by Greiner. The installment team came (three members) and were professional, courteous, and knowledgeable! When it was completed they were careful to vacuum the carpets and were very detail oriented. This is the second HVAC system they have replaced, last year they replaced the ducts, insulation, and the entire system and for the first floor. Fair price with multiple discounts, knowledgeable estimator, polite and caring office staff, and skilled installation teams. From beginning to end the process was easy, fast, and affordable. Thanks Greiner for another positive experience! read more

After so many years that we have owned our home, I finally decided to have our dual Air Conditioning system maintenance service. Today Angel R. Was our Service Technician. My appointment was from 12:00 to 3:00pm and Angel actually came early. He was extremely thorough by checking out our heating system and AC system. He found a few issues and recommended changing out some failing parts which I agreed to. The Freon in both AC units was very low and he charged it back up to normal. Wow! What a difference! It's 3:45pm and he just left. 5 Star Service from start to finish by the Greiner Team and most importantly, Angel's services today. I'm so glad I chose Greiner! read more

Buyer Beware: We purchased our solar system. Recently, we changed our Internet provider and called to get help in changing the system because when you change Internet provider, your in phase is not reporting the data when I called to get Assistance. They told me we were gonna have to pay 3 to $400 to get that change. I let the assistant know that answer the phone that we never paid for that help before which previously we changed an Internet provider a few years ago and she checked on it and said well now we have to pay. I am not happy at all with this and the only thing she could tell us is they could send us directions and how to do it. My Advice to you is get someone else and not do the solar through them. and just so customers could be aware we have been using Greiner for many years. I've lived in my current location since March 1993 my first husband and I purchased our heating and air system in 2010 and since then we now have a new system that we got a few years back and we've gotten an upgrade in the ducks in the attic. We purchased a electric water heater and we've gotten some other stuff through Greiner. We pretty much used them for everything in addition, we pay a monthly fee to maintain our systems so I guess I was extremely surprised that we couldn't get any help without paying the three to $400 fee to help with updating our Internet read more

Is there a word that expresses something that is "better than excellent?" There were so many challenges with my heating and air units that contractors who came to bid took one look and either refused the job or bid such exorbitant prices that I wondered if I would ever get them replaced. While the other guys told me why so many things wouldn't work, Alix the Greiner sales guy, whipped out his measuring tape and started to think of possibilities. Then he brought over Greiner's most senior team members to come up with a game plan. They took out a huge obstacle blocking access to the units that took half a day and all were not only polite, but cheerful. You could feel the great managers of the company through their workers. I was and am blown away by the company's performance and reasonable pricing. Think of a word that is better than "excellent" and you are describing Greiner. Hire them. read more

I had an excellent experience with Greiner. First, Ray came out to diagnose my old AC unit as it was making a strange whirring noise. He suggested that I probably get the unit replaced but told me that a design specialist would come out the next day to explain my options to me. Second, Alex came the next day. He went into my attic checked out my system and thoroughly explained to me my options and what I needed to repair things, but also what I could potentially do to improve the system effeciencies and personal comfort with a newer system. Alex was not pushy to improve to the most expensive unit and provided really good thoughtful advice on the best option for me and my family. Third, Eduardo and Marcus came out for the install. Both arrived promptly and worked effecienctly with respect for my home. They did a great job with the installation, answered all my questions, and made sure I understood how to use my system before they left. They were also very clean and cleaned up after their departure. Ernesto, Armando, and Marco also joined Eduardo and Marcus during the install and everyone was extremely professional. Fourth, about a week after the install, there was a small issue with one of the units and Greiner sent out a technician within an hour. Ernesto came out, diagnosed the issue, and resolved it very promptly. I highly reccomend giving Greiner a bid for any future HVAC projects you may have. Their quality and attention to detail was very much appreciated. read more

Had my ac replaced last year. All good. Good prices, great people, excellent service, while they were in my home and afterwards. Everyone is helpful and friendly. I recommend them to all I talk to. read more

Our A/C stopped working. The condenser made noise but the cooling fan did not turn. We called Greiner. * Response time. FIVE STARS. A technicians came the next day. * Price. FOUR STARS. We paid $652.24 for replacing a capacitor and troubleshooting. They proposed additional work for $2,106.85. We passed. * "Discovery" of dangerous situation. ONE STAR. The tech told us that our heat exchanger was cracked. This would let carbon monoxide leak out when we turn on the heater. He suggested we should replace the heat exchanger or the furnace or the entire furnace A/C combination. We did not act on the recommendation because this was July and we have several months to research the solution and the vendors. * Quality. FIVE STARS. Another tech called the next day and asked if he could come over to doublecheck the cracked heat exchanger. He said the first tech did not leave photos of the crack in the heat exchanger. He took the furnace apart and found no crack. * Bottom line. FOUR STARS. We like that they fixed out A/C. We are OK with the $600+ price to replace a $30 capacitor. We like that the second tech doublechecked the claim of cracked heat exchanger. We like that they provided photos. We might call this outfit if we have problem the next time, but we don't know which tech will come. read more

Prompt, courteous, thorough, totally professional. Cleaned the furnace and heating system. Did not try to sell me more services or equipment (as so many of the HVAC folks do). Technician David went from the attic to the basement, taking photos every step of the way. I highly recommend. read more

Greiner has come out and serviced our ancient 50 year old HVAC system twice in the last year and gotten it running again. They're fast, efficient, and willing to do what they need to do in the short term, while also discussing long-term options. We know we'll need to replace our unit sooner rather than later. Thanks to Greiner, we have a bit more time to save up for a new system. read more

Thank you Greiner, as always a pleasant and informative experience. David was professional, explained things to me well. I have trusted you company and staff for honesty and to not push me into things unless a major is identified. Thank you again. read more

Greiner completely revamped our existing HVAC system. They installed new units and added zoning to our two story home. Our old gas furnace was replaced by an electric unit and they freed up a closet for us, which is awesome. Since they also do electrical work, it was a one-stop shop for the entire project. The electricians also put recessed lights in our family room and ceiling lights in all the bedrooms. We couldn't be happier with everything. The new system works great and is much more efficient. Every staff member was respectful and top-notch at what they did. I'd highly recommend Greiner for any project involving HVAC and/or electric. read more

Called today for a system issue. Have a tech coming tomorrow between 8-10. Luckily it is not a heat wave like last week. Very responsive and understanding on the phone call. Will update once tech arrives tomorrow and figures out why our system blew a fuse. read more

I recently had my entire air conditioning system replaced by Grenier after having an unfortunate experience with another company. They turned a nightmare into a dream come true and installed a system that is virtually silent. The staff were exceptional! Competent, courteous, and timely. I owe a special gratitude to Christian Arana, my Service Technician and the team of my Installers; Cody, Marco, and Marcus. I can't say enough about the company and their quality of work. read more

So, our AC unit kinda went kaput, as far as we were aware, and its over twenty three years old, this was July fourth. We panicked as it was super hot, my parents are elderly and we have pets. Greiner was my first call, then five others. We finally got one from another company, for a July five appointment, he said unit was toast, offered replacement and price for new system. July sixth, Greiner comes for the scheduled appointment, and estimate on new system. Tech, was professional, understanding, sympathetic and upfront. He looked at our system, ran a circuit check, said he could fix it, temporarily, as he was concerned for my parents. System is running, house is cool, and now we can relax, until we get new system, which will be asap. THANK YOU CRISTIAN, Thank you Greiner, you will always be my first call. read more

Returning customer. This time for a new water heater. Original call was to come out and take a look at the current water heater and give me the bad news. Was very up-front about my choices and explained what they could do. So, I got a new water heater. Installation was very fast which surprised me. All done within a few days. Thank you Edgar and the team. read more

Greiner's scheduled maintenance checks, one for heating, one for cooling, are a great value. We recently received our cooling season service. Ray and Angel were thorough and considerate, fine-tuning our system, cleaning the coils and monitoring the performance of the equipment. Turns out our compressor is drawing a little more electricity than normal. No hard-sell, Ray and Angel were forthright about this, explained options and followed up with a quote with several options via email the next day. Overall, we are very pleased with the service and care we received and now know our system will operate dependably and efficiently. Plus, it was great to talk a little baseball, too. read more

Greiner Heating, Air and Electric - Ray & Angel - great service - Heating & Air Conditioning/HVAC Near Me - Dixon, California

Thanks, Greiner Heating and Air for the professional and smooth installation of our new Lennox Heat Pump HVAC system. After 40 years of commercial construction, I have worked with many contractors and Greiner ranks amongst the best, in my opinion. The estimator found rebates that other competing contractors missed, saving thousands of dollars. The 4 person crew was efficient, professional, and clean. The communication and timeliness were outstanding. I strongly recommend Greiner Heating and Air. read more

Had another excellent check-up on our AC unit by Daniel James with Greiner Heating and Air! Daniel was friendly, knowledgeable and professional. He has been to our home before and treats us like family. We appreciate Greiner Heating and Air so much. They come twice a year to check on our heater for the fall & winter and then our AC unit for spring & summer. We got our new water heater through Greiner as well. They gave us a great deal and we have had no problems with any of the work they have done. ThAN YOU Greiner! read more

Greiner replaced our old system with a new heat pump furnace and AC system. They also installed a tankless water heater. While the work done was good, they seem very high priced and are constantly pushing add-ons and extras. I should have gotten more estimates. I also recommend always taking a day or two and researching the add-ons they will try to sell you later on. I am not sure but their technicians may be selling you equipment on a commission, which seems like a conflict of interest between serving the customer and adding to their paycheck. So overall I would compliment the quality of the work but question the super high pricing and pressure to buy add-ons. Shop around. read more

Sam and Enrique recently installed a new HVAC system, reworked our ducts and blew in insulation and they did an excellent job. They were very professional, explained to me what they were doing and left the property clean when they left. They were very considerate and I appreciate everything they did. We have had a maintenance plan with Greiner for years and will continue to do so. read more

I've had a service plan with Greiner for about 5-years now and have been very happy with the service. During that time, they gave me a heads up on the performance of my HVAC in addition to keeping it going until we could find a good deal on financing. Like so many HVAC companies, I've never felt like they were pushing me for an up-sell. read more

Called on Wednesday evening and they showed up the next day and earlier than expected. Chris was knowledgeable and friendly. He fixed the problem with our AC unit and explained the process and what to probably expect I. The future with our unit. The customer service ladies who made the appt. Kept me up to date with the process and very friendly. read more

With the weather warming up we decided to test out the air conditioner and good thing we did. It was not cooling and so had to call someone. We called another place but they couldn't fit us in until next Tuesday. After checking on the warranty we decided to call the manufacturer who ended up giving us Greiners name and connecting us to the company. They gave us a Saturday time but ended up calling us later in the day saying they were in the neighborhood. We were home so perfect timing. They did an inspection and found refrigerant was low. After checking a few other possibilities it was settled on the refrigerant. Jacob was very friendly, explained everything and made sure to wear a mask and booties in the house. Very happy with the response and with the service. He said if any issues to contact them again and they would be out. Thank you for the great service. read more

Very poor customer service. Unresponsive and unhelpful. After spending $25,000 with them, no thanks or appreciation for my business. No follow-up after installation. Not recommended. read more

I asked for a quote which was performed by their estimator who was VERY personable and professional. I wanted to look at a mini split system rather than replace my original compressor and ducting system for which I had already received a quote from another HVAC contractor. The quote was figured by entering numbers into his laptop in a program. The number it came out with was 150% of the quote to replace the existing system. Also, the program provided NO breakdown of the estimate showing equipment and installation numbers separately. As an engineer, I am use to getting quotes in a format showing all separate associated costs. I asked if they could do the installation of owner purchased equipment and he said " We don't do it that way" I know they have a good reputation but the quote received was WAY TO HIGH! read more

Our AC failed during the big heat wave in September in Dixon. Since Greiner installed our AC system, I called them to come out and diagnose the problem. The tech arrived the next day and said the problem was a burst capacitor. I asked how much to replace that part and they quoted $300+. I thought, "this must be a really expensive capacitor!" They put in about an hour of work. Later, I found the capacitor only costs about $17. So we paid about $325 for one hour's work! In addition to that, we still had to pay the initial "visit fee" of about $90. One would think they'd drop that, since the real job was so expensive. I'm through using Greiner -- they are way too expensive. read more

My parents had Greiner out to look at their thermostat. the unit on the wall wasn't showing the numbers clearly and wouldn't change temp. the technician that came out told them they needed a new thermostat and it would cost $1600 dollars. taking complete advantage of elder folks. thankfully my parents said no. we were able to replace the thermostat for $140. i don't recommend this company and be very cautious and get a second opinion if you have them out. read more

I hired Grenier to replace my aging and poorly installed central heat and A/C ducts. They did a great job, designing and installing a much better ducting system. I only had one issue with their work, and they promptly came back and fixed it - so great resolution of problems! I just hired them again for the annual maintenance of my furnace and A/C - plus my water heater. read more

We just wrapped up a very large job with Greiner and I must say you get what you pay for... In a good way.. They were definitely not the cheapest bid we got, in fact, they were one of the higher bids, but the attention to detail, the customer service, and just plainly their behavior during their project made it worth every penny. We replaced our entire HVAC system, including all of the duct work in our attic. It was a very big job, but at every corner, they took the time to constantly describe every detail and explain things to my elderly mom (since it was her home). Even when some small mistakes were made, we noticed some small leakages, they immediately came out several times to make sure it was taken care of right away. All in all, their staff are absolutely top notch and we've worked with many other contractors in the area. Thanks Greiner for an incredible job well done. read more

Probably saved our lives. An exhaust vent became detached from the vent in the roof - pouring CO2 and water into the attic- the technician found the problem, and fixed it... no idea how long it was like that - but we're thankful it was found. read more

We had a new air conditioning unit and furnace installed last week. We are very happy with the service we were provided. Noah, Sarn, Eduardo and Diego showed up on time and were very professional.
