A-1 GUARANTEED’S CUSTOMER TESTIMONIALS
Here is what our customers have to say about us…
Here is what our customers have to say about us…The installers were polite – the way it “use to be”, even though they were younger. I thought the younger generation lacked the respect we were taught and they showed us otherwise – thanks.
– S. Jarden, Concord
This company from top to bottom is first class all the way – I must have had 8-10 other quotes and the people that came out were very disappointing. From your sales estimator to the gentleman who installed my furnace I couldn’t be happier. Your company is absolutely outstanding in every phase – there isn’t another company that even comes close – Thank you very much. I wish every company was like yours – you set the standard what a company should be like – absolutely top notch.
– K. Freigen, Concord
I think your company and installers are “Tops”. Wish all jobs I need could be as good. I have already recommended you to all my friends who will need your type of services in the future.
– E. Sillin, Napa
Very knowledgeable people. I was really impressed when the owner himself came out the day we signed the contract. He changed a few items i.e. a bigger unit at no additional cost to us. The house was very clean when they left. My only regret was not going through them directly; however I have no qualms with Home Depot. Thanks everyone for making our home a place we look forward to coming home to on a hot day.
– A. Alvey, Concord
Your company is the best – this is my 3rd A-1 Guaranteed furnace – that says it all.
– S. McDonald, Vallejo
As a real estate broker, I am called on to hire many different service contractors for my clients. There is an enormous difference in the knowledge, courteousness and professionalism of A-1 Guaranteed as compared to most other companies I’ve dealt with – you guys get the “Gold Star”!
– S. Clare, Martinez
We can’t “thank you” enough for your kindness & professionalism of everyone. You were able to handle my personal needs & did so with grace. You were able to complete the project faster than anyone thought that it could be done! I can’t thank you enough!
– S. Miller, Vallejo
They are friendly people, get the job done on time, you could not ask for better service
– Charles Booker – Fairfield
We really appreciated the prompt service we received. They were prompt for every appointment, from the initial service call to diagnose the problem, to the actual installation. We are so pleased with their service that we have an annual service contract with them.
– I.S.U. Saunder Jacobs – Napa
Bob’s initial visit, followed by Richard’s home assessment, convinced me this was the company I wanted for installing central heating in my home. The arrival of the 3 person team (Dan, Joe & Rick) were the “frosting on the cake!” Everyone is knowledgeable about their product and their duties. They acted in a professional manner at all times. By this I mean they were cheerful, took responsibility for their duties, were informative, enthusiastic, focused on the job yet flexible when necessary and demonstrated confidence in their work. Richard has built an excellent team and he is well organized and demonstrates a good deal of integrity.
– A Satisfied Customer
I felt I was kept informed and updated on all scheduled appointments. A 2 hour window was very easy to deal with compared to 4 hour windows I have received from almost any other company I have dealt with in the past. Thank you
– Patty – Hercules
Joe, Tom & Bo installed our Trane system. They were very pleasant and easy to deal with. All were professional and left our home cleaned up. It was a pleasure to do business with them.
– Teresa Waller – Fairfield
The sales representative (Bob) was very nice, prompt, took care of everything and checked back to see how everything went. Thank you. Joey was very nice and respectful of my house. He took care of everything, explained how to clean filters, etc.
– Dorothy Arzadon – Vallejo
These fine folks know what they talk when it comes to furnace and a/c installations. They are prompt, diligent and highly professional in all manners of their work. Many thanks!
– Doug Nelson
My Trane was installed on Nov. 11 before the rains. They set it up the way I wanted it. When I get up in the a.m. my house is warm. They were friendly, courteous. They cleaned up the mess before they left. In fact, my Trane got installed one week early which made me happy.
– Florence Hayes
I am enjoying my heater very much. The warmth of my home is so comfortable. A-1 Guaranteed did a great job. Thank you.
– Nellie Barr – Vallejo
Efficiency and caliber of personnel doing installation of our air conditioner and heater was impressive. They worked very hard even though they had 102 degree heat to work in that day. This company’s efficiency is amazing and they’ve done an excellent job and we would certainly recommend them to anyone.
– Yvonne Lafferty – Vallejo
The quality of the installation was exceptional and was finished in a timely manner. I expected the install to last the whole day but instead it was done in several hours. The installer completed the job quickly and professionally. He did not try to force any unnecessary parts or labor on me.
– F. Pagala – Vallejo
They arrived promptly at the time they had informed me. Minimal interruption to my household activities, they completed the work without disruption. They maintained clean working area and left my house exactly as it was when they entered. Installers answered all my questions, explained maintenance and operation. It was a pleasure to feel as though a contractor was not out to take advantage of you or rip you off.
– Patrick Cannon – Vallejo
Joe & Dan were very knowledgeable and professional. They worked all the time they were here. The job was completed and the area was cleaner when they finished than when they started. They did everything as promised and I am very satisfied. Everything is working as it should be. You will be very lucky if you hire them to do your installation. A-1 Guaranteed is fair and great at what they do.
– Ted Essy – Vallejo
We are glad we chose A-1 Guaranteed first because it is local and easy to get service or information if needed. Also, we are glad they are members of the Better Business Bureau. We found Richard and his workers very courteous and knowledgeable of the Trane product they installed.
– Angel Tribo – Vallejo
It is so nice to have every room cool. It doesn’t take long to get cool either. We are really enjoying our new central air and can’t wait for winter to enjoy our heat. Richard and his crew were great. They were neat, very polite and trustworthy. We would recommend them highly. As a matter of fact, we already have.
– Jack Murray – Vallejo
Courteous beyond description. If not perfect – never had a group of people tried harder to be. Very accommodating to my specific requests regarding installation and my schedule.
– Doug Taylor – Fairfield
Richard was quick to come and look at the job when I called. He took great pride in the work that needed to be done. He came by to check on how the job was going and all of his workers were very friendly and helpful. Joe was very nice and helpful, he went over everything with me to make sure I know how to work everything. Joe went the extra mile to build a box so my heater would work better. I would use him again if I wanted another job done.
– Richard Davis – Vallejo
Richard and Becky were very professional. He answered all my questions. He was prompt and very friendly. Talking to Becky over the phone made the experience easier. I am so pleased with their service I have recommended them to several individuals. After shopping around, they had the best price for what was needed in my home. The installer was efficient and very knowledgeable. He explained in detail how to operate my new air conditioner. The most of what really impressed me was Richard’s follow-up on his installation. Thanks for the great job and savings.
– Reginald Bethancourt, – American Canyon
It’s really a beautiful machine and it efficiently provides both heat and air conditioning. As a bonus, it can be used simply to circulate air – as they say, “It’s hard to stop a Trane.” Joe and John were professional and easy to work with. I observed much of the work and as a “Do-It-Yourselfer” I appreciated the tips they gave me, so if I rebuild a floor or add tiles, I can do it myself without having to call someone….the guys are great!
– John Kocourek – Vallejo
After discussing our need for a new heating system with Richard, we believed he could do the job to our satisfaction and he did. The Trane system is what we needed and we will tell everyone that Trane and A-1 Guaranteed is the BEST.
– Jimmie Moore – Vallejo
Once the installer put the air conditioner on we could feel the difference right away. The air smelled clean and the house cooled down within 5 minutes from the time he turned it on. The Trane air conditioner unit is very nice. Overall, A-1 Guaranteed did a GREAT JOB!! The installers were here on time. They came in and assessed the house for the job they were going to do. They came in and did the job in a timely manner and didn’t make a mess, they cleaned up after themselves and went over how to use the system.
– Mary Cowper – Vallejo
The process may seem a tad scary at first and you may wonder if it’s really worth it or how does it actually work or when will I see the savings? At this point I have already saved money depending on the way you look at it. My PG&E bill is nonexistent now and I don’t have to keep yelling at everyone to turn off the lights or not heat the hot tub. Read More..
